Detailed Description

The present invention will be described in further detail with reference to the attached drawings, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

fig. 1 is a schematic diagram of a light supplement lamp control process provided in an embodiment of the present invention, where the process includes the following steps:

s101: according to a light supplement pixel range corresponding to a first light supplement lamp in an image in a predetermined monitoring scene, determining a first pixel row corresponding to a first object and a second pixel row corresponding to a second object in the light supplement pixel range, wherein the distance between the first object and the first light supplement lamp is a first distance, the distance between the second object and the first light supplement lamp is a second distance, and the first distance is larger than the second distance.

S102: and controlling the first light supplement lamp to be turned on at the exposure starting time of the first pixel row, and controlling the first light supplement lamp to be turned off after the exposure starting time of the second pixel row and before the exposure finishing time of the first pixel row.

The light supplement lamp control method provided by the embodiment of the invention is applied to electronic equipment, and the electronic equipment can be equipment such as a PC (personal computer), a tablet personal computer and the like.

In a monitoring scene, after the configuration of the light supplement lamp is completed, the light supplement pixel range corresponding to the light supplement lamp in the image is determined, the electronic device can determine the light supplement pixel range corresponding to the light supplement lamp in the image in advance, and then a first pixel row corresponding to a far object and a second pixel row corresponding to a near object in the determined light supplement pixel range. It should be noted that, in a monitoring scene, when an irradiation range of one fill-in lamp can cover the whole image, only one fill-in lamp may be configured; when the irradiation range of one fill-in light lamp can not cover the whole image, can dispose a plurality of fill-in lights. In the embodiment of the present invention, a light supplement lamp to be currently controlled is referred to as a first light supplement lamp, and after a light supplement pixel range corresponding to the first light supplement lamp in an image is determined, a first pixel row corresponding to a first object closer to the first light supplement lamp and a second pixel row corresponding to a second object farther from the first light supplement lamp in the light supplement pixel range are determined.

Taking the example of configuring a first fill-in light in the monitoring area, the smaller the number of pixel lines in the general image is, the farther the first fill-in light is from the object, the larger the number of pixel lines is, and the closer the first fill-in light is to the object. Assuming that the image includes N pixel rows, a first pixel row corresponding to a farthest object in the determined fill-in pixel range is a first row, and a second pixel row corresponding to a nearest object is an nth row. And controlling the first light supplement lamp to be turned on at the exposure starting time of the first row, and controlling the first light supplement lamp to be turned off after the exposure starting time of the Nth row and before the exposure finishing time of the first row.

Fig. 2 is a schematic diagram illustrating control over a fill-in light when a first fill-in light is configured according to an embodiment of the present invention, as shown in fig. 2, an image includes N pixel rows, and from row 1 to row N, the closer an object to be photographed, which has the larger number of rows, is to a camera, the farthest object in the fill-in light pixel range corresponds to the first row, and the closest object corresponds to the nth row. And in a frame interval time length, controlling the first light supplement lamp to be turned on at the exposure starting time of the first row, and controlling the first light supplement lamp to be turned off after the exposure starting time of the Nth row and before the exposure finishing time of the first row. As shown in fig. 2, the exposure start times of two adjacent pixel rows of the image sensor differ by one readout time, in the embodiment of the present invention, the first fill-in light is controlled to be turned on at the exposure start time of the first pixel row corresponding to the distant object, and the first fill-in light is controlled to be turned off after the exposure start time of the second pixel row corresponding to the close object and before the exposure end time of the first pixel row. The effective light supplementing time of the near object is shorter, and the effective light supplementing time of the far object is longer. Therefore, the problem that the light supplement lamp has large difference in light supplement effect on the far object and the near object and cannot meet the light supplement requirements of the far object and the near object at the same time is solved.

Example 2:

in order to ensure that there is no mutual influence between two adjacent frames of images, so as to further ensure the image quality, on the basis of the above embodiment, in an embodiment of the present invention, the controlling the first fill light to turn off after the exposure start time of the second pixel row and before the exposure end time of the first pixel row includes:

and after the exposure starting time of the second pixel row and before the exposure ending time of the first pixel row, and before the exposure starting time of the first pixel row of the next frame image, controlling the first fill light to be turned off.

In the embodiment of the invention, in order to ensure that no mutual influence exists between two adjacent frames of images, a time limiting condition is added when the first fill-in lamp is controlled to be turned off, wherein the time limiting condition is that the first fill-in lamp is controlled to be turned off before the exposure starting time of the first pixel row of the next frame of image. When a plurality of light supplement lamps are arranged in a monitoring scene, each light supplement lamp determines that a corresponding light supplement pixel range exists, and for each light supplement lamp, the light supplement lamp can be controlled to be turned off after the exposure starting time of the second pixel row and before the exposure ending time of the first pixel row and before the exposure starting time of the first pixel row in the light supplement pixel range of the light supplement lamp in the next frame image. Or the supplementary lighting lamp can be controlled to be turned off after the exposure starting time of the second pixel row and before the exposure ending time of the first pixel row and before the exposure starting time of the first pixel row of the whole image in the next frame image.

In the embodiment of the invention, the first fill-in light is controlled to be turned on at the exposure start time of the first pixel row, and is controlled to be turned off after the exposure start time of the second pixel row and before the exposure end time of the first pixel row and before the exposure start time of the first pixel row of the next frame image. The light supplement between two adjacent frames of images is prevented from influencing each other, and the image quality is further improved.

Example 3:

on the basis of the foregoing embodiments, in an embodiment of the present invention, before controlling the first fill light to be turned off after the exposure start time of the second pixel row and before the exposure end time of the first pixel row, the method further includes:

when the monitoring scene further comprises at least one second light supplement lamp, judging whether light supplement pixel ranges of the first light supplement lamp and the at least one second light supplement lamp are not overlapped, if so, performing the subsequent step of controlling the first light supplement lamp to be closed after the exposure starting time of the second pixel row and before the exposure finishing time of the first pixel row;

or when the monitoring scene further comprises at least one second light supplement lamp, judging whether the light supplement pixel range of the first light supplement lamp is the light supplement pixel range corresponding to the nearest object in the image, if so, performing the subsequent step of controlling the first light supplement lamp to be turned off after the exposure starting time of the second pixel row and before the exposure ending time of the first pixel row.

In the embodiment of the present invention, when at least two light supplement lamps are configured in a monitored scene, that is, when the monitored scene includes a first light supplement lamp and at least one second light supplement lamp, light supplement pixel ranges of the first light supplement lamp and the at least one second light supplement lamp may or may not overlap. In the embodiment of the present invention, in order to ensure that the light supplement lamps do not affect each other, and thus further ensure image quality, after the exposure start time of the second pixel row and before the exposure end time of the first pixel row, before controlling the first light supplement lamp to turn off, it is first determined whether light supplement pixel ranges of the first light supplement lamp and the at least one second light supplement lamp do not coincide with each other, if not, that is, the light supplement ranges of the first light supplement lamp and the at least one second light supplement lamp are separated from each other, and as long as after the exposure start time of the second pixel row and before the exposure end time of the first pixel row, controlling the first light supplement lamp to turn off does not affect other second light supplement lamps.

Or, the electronic device determines whether the light supplement pixel range of the first light supplement lamp is the light supplement pixel range corresponding to the nearest object in the image, and if so, it indicates that the last line of the light supplement pixel range of the light supplement lamp does not coincide with the light supplement pixel ranges of other second light supplement lamps, so that after the exposure start time of the second pixel line and before the exposure end time of the first pixel line, controlling the first light supplement lamp to be turned off does not affect the other second light supplement lamps.

In the following, three fill-in lamps are configured, and the fill-in pixel ranges of the three fill-in lamps are not overlapped.

As shown in fig. 3, the light filling pixel range of the light filling lamp 1 corresponds to the 1 st line to the Q th line of the image, the light filling pixel range of the light filling lamp 2 corresponds to the Q +1 th line to the P th line of the image, and the light filling pixel range of the light filling lamp 3 corresponds to the P +1 th line to the N th line of the image. The object corresponding to the light supplement lamp 1 is farthest, and the object corresponding to the light supplement lamp 3 is nearest.

Fig. 4 is a schematic diagram illustrating control of the fill-in light according to an embodiment of the present invention, and as shown in fig. 4, the fill-in light 1 is controlled to be turned on within an exposure time period of a 1 st row, and the fill-in light 1 is controlled to be turned off within an exposure time period of a Q th row. And controlling the light supplement lamp 2 to be turned on within the exposure time length of the Q +1 th line, and controlling the light supplement lamp 2 to be turned off within the exposure time length of the P-th line. And controlling the light supplement lamp 3 to be turned on within the exposure time length of the P +1 th line, and controlling the light supplement lamp 3 to be turned off within the exposure time length of the Nth line. Preferably, the fill light 1 is controlled to be turned on at the starting time within the exposure time of the 1 st row. And controlling the light supplement lamp 2 to be started at the initial moment within the exposure time length of the Q +1 th line. And controlling the light supplement lamp 3 to be started at the initial moment within the exposure time length of the P +1 th line. Thereby further improving image quality.

As shown in fig. 3, for the fill-in light 1, the effective fill-in light time of the image sensor in the 1 st row is the longest, and the effective fill-in light time of the Q-th row is the shortest. For the fill-in light 2, the effective fill-in light time of the image sensor on the Q +1 th line is the longest, and the effective fill-in light time of the P-th line is the shortest. For the fill-in light 3, the effective fill-in light time of the image sensor on the P +1 th line is the longest, and the effective fill-in light time of the nth line is the shortest. That is to say, the effective light supplementing time of the near object is shorter, and the effective light supplementing time of the far object is longer. Therefore, the problem that the light supplement lamp has large difference in light supplement effect on the far object and the near object, and cannot meet the light supplement requirements of the far object and the near object at the same time, and the image quality acquired under the light supplement condition is poor is solved.

Example 4:

on the basis of the foregoing embodiments, in an embodiment of the present invention, if light supplement pixel ranges of the first light supplement lamp and at least one second light supplement lamp overlap, and the light supplement pixel range of the first light supplement lamp is not a light supplement pixel range corresponding to a nearest object in the image, after an exposure start time of the second pixel row and before an exposure end time of the first pixel row, controlling the first light supplement lamp to turn off includes:

and after the exposure starting time of the second pixel row, before the exposure ending time of the first pixel row and before the exposure starting time of a third pixel row adjacent to the second pixel row, controlling the first supplementary lighting lamp to be turned off.

In the embodiment of the present invention, when the light supplement pixel ranges of the first light supplement lamp and the at least one second light supplement lamp are overlapped, and the light supplement pixel range of the first light supplement lamp is not the light supplement pixel range corresponding to the nearest object in the image, in order to ensure that there is no mutual influence between the first light supplement lamp and the at least one second light supplement lamp, it is to be avoided that two light supplement lamps having the overlapped light supplement pixel ranges simultaneously supplement light for a certain row of pixels. The method comprises the following steps of controlling a first supplementary lighting lamp to be turned off after the exposure starting time of a second pixel row, before the exposure ending time of a first pixel row and before the exposure starting time of a third pixel row adjacent to the second pixel row. Therefore, only one light supplement lamp can supplement light for the same pixel row, no mutual influence among the light supplement lamps is guaranteed, and image quality is further guaranteed.

It should be noted that the fill light in the embodiment of the present invention includes a stroboscopic fill light, and the stroboscopic fill light includes a white-light stroboscopic fill light and an infrared stroboscopic fill light. The method for controlling the light supplement lamp provided by the embodiment of the invention does not need to change an optical structure, and has small hardware change, so the scheme cost is low. The method is suitable for a single light supplement lamp scheme and a multi-light supplement lamp scheme. The method can be combined with other existing supplementary lighting control schemes. Meanwhile, the effective light supplementing time at different distances can be adjusted steplessly.

The communication interface 302 is used for communication between the above-described electronic apparatus and other apparatuses.

The Memory may include a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as at least one disk Memory. Alternatively, the memory may be at least one memory device located remotely from the processor.

The Processor may be a general-purpose Processor, including a central processing unit, a Network Processor (NP), and the like; but may also be a Digital Signal Processor (DSP), an application specific integrated circuit, a field programmable gate array or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or the like.

When the processor executes a program stored in the memory in the embodiment of the present invention, determining a first pixel row corresponding to a first object and a second pixel row corresponding to a second object in a light supplement pixel range according to the light supplement pixel range corresponding to a first light supplement lamp in a predetermined monitoring scene in an image, where a distance between the first object and the first light supplement lamp is a first distance, a distance between the second object and the first light supplement lamp is a second distance, and the first distance is greater than the second distance; and controlling the first light supplement lamp to be turned on at the exposure starting time of the first pixel row, and controlling the first light supplement lamp to be turned off after the exposure starting time of the second pixel row and before the exposure finishing time of the first pixel row. In the embodiment of the invention, in order to reduce the difference of the light supplement effect between the near object and the far object, the effective light supplement time of the light supplement lamp corresponding to the near object is configured to be shorter, and the effective light supplement time of the light supplement lamp corresponding to the far object is configured to be longer. Specifically, the purpose is achieved by setting the on and off time of the light supplement lamp. The effective light supplement time refers to the coincidence time of the exposure time length of each pixel row and the starting time length of the light supplement lamp. Because the exposure starting time of two adjacent pixel rows of the image sensor differs by one reading time, the light supplement lamp is controlled to be turned on at the exposure starting time of the first pixel row corresponding to a distant object in the embodiment of the invention, and the light supplement lamp is controlled to be turned off after the exposure starting time of the second pixel row corresponding to a close object and before the exposure ending time of the first pixel row. The effective light supplementing time of the near object is shorter, and the effective light supplementing time of the far object is longer. Therefore, the problem that the light supplement lamp has large difference in light supplement effect on the far object and the near object and cannot meet the light supplement requirements of the far object and the near object at the same time is solved.

Example 7:

on the basis of the foregoing embodiments, an embodiment of the present invention further provides a computer storage readable storage medium, in which a computer program executable by an electronic device is stored, and when the program is run on the electronic device, the electronic device is caused to execute the following steps:

determining a first pixel row corresponding to a first object and a second pixel row corresponding to a second object in a light supplement pixel range according to the light supplement pixel range corresponding to a first light supplement lamp in a predetermined monitoring scene, wherein the distance between the first object and the first light supplement lamp is a first distance, the distance between the second object and the first light supplement lamp is a second distance, and the first distance is greater than the second distance;

and controlling the first light supplement lamp to be turned on at the exposure starting time of the first pixel row, and controlling the first light supplement lamp to be turned off after the exposure starting time of the second pixel row and before the exposure finishing time of the first pixel row.

Based on the same inventive concept, embodiments of the present invention further provide a computer-readable storage medium, and since a principle of solving a problem when a processor executes a computer program stored in the computer-readable storage medium is similar to that of a fill-in light control method, implementation of the computer program stored in the computer-readable storage medium by the processor may refer to implementation of the method, and repeated details are not repeated.

The computer readable storage medium may be any available medium or data storage device that can be accessed by a processor in an electronic device, including but not limited to magnetic memory such as floppy disks, hard disks, magnetic tape, magneto-optical disks (MOs), etc., optical memory such as CDs, DVDs, BDs, HVDs, etc., and semiconductor memory such as ROMs, EPROMs, EEPROMs, non-volatile memory (NAND FLASH), Solid State Disks (SSDs), etc.

In the computer-readable storage medium provided in the embodiment of the present invention, a computer program is stored, and when the computer program is executed by a processor, the method includes determining, according to a light supplement pixel range corresponding to a first light supplement lamp in a predetermined monitored scene in an image, a first pixel row corresponding to a first object and a second pixel row corresponding to a second object in the light supplement pixel range, where a distance between the first object and the first light supplement lamp is a first distance, a distance between the second object and the first light supplement lamp is a second distance, and the first distance is greater than the second distance; and controlling the first light supplement lamp to be turned on at the exposure starting time of the first pixel row, and controlling the first light supplement lamp to be turned off after the exposure starting time of the second pixel row and before the exposure finishing time of the first pixel row. In the embodiment of the invention, in order to reduce the difference of the light supplement effect between the near object and the far object, the effective light supplement time of the light supplement lamp corresponding to the near object is configured to be shorter, and the effective light supplement time of the light supplement lamp corresponding to the far object is configured to be longer. Specifically, the purpose is achieved by setting the on and off time of the light supplement lamp. The effective light supplement time refers to the coincidence time of the exposure time length of each pixel row and the starting time length of the light supplement lamp. Because the exposure starting time of two adjacent pixel rows of the image sensor differs by one reading time, the light supplement lamp is controlled to be turned on at the exposure starting time of the first pixel row corresponding to a distant object in the embodiment of the invention, and the light supplement lamp is controlled to be turned off after the exposure starting time of the second pixel row corresponding to a close object and before the exposure ending time of the first pixel row. The effective light supplementing time of the near object is shorter, and the effective light supplementing time of the far object is longer. Therefore, the problem that the light supplement lamp has large difference in light supplement effect on the far object and the near object and cannot meet the light supplement requirements of the far object and the near object at the same time is solved.
