Detailed Description

(first embodiment)

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a block diagram showing a configuration of a data communication device according to a first embodiment.

(Structure of data communication device)

As shown in fig. 1, the data communication device 10 according to the first embodiment is characterized by including an operation unit 105, an image reading unit 110, a storage unit 120, an email transmission unit 130, an image data detection unit 140, an image data amount determination unit 150, a communication control unit 160, a data amount control unit 170, and a control unit 180 that controls the operation of each unit, and the data communication device 10 is capable of transmitting an email to which an image is attached.

The operation unit 105 includes a display panel 106. The display panel 106 displays a display screen for touch operation. The operation unit 105 is configured to be capable of performing setting and instruction operations of each unit on the display screen.

The image reading unit 110 is, for example, a scanner and reads an image.

The storage unit 120 stores data of the image read by the image reading unit 110 as read image information 121.

The email transmission unit 130 attaches the read image to an email and transmits the email.

The image data detection unit 140 detects the data amount of the read image.

In the data communication apparatus 10, the data amount of an image that can be transmitted in addition to an email is set in advance. The maximum value of the data amount can be set or changed.

The image data amount determination section 150 determines whether or not the data amount of the image attached to the e-mail exceeds a preset data amount.

The communication control unit 160 can transmit the email if the data amount of the image attached to the email does not exceed the preset data amount.

When the data amount of an image attached to an electronic mail exceeds a preset data amount, the data amount control unit 170 performs data amount reduction processing 171 for reducing the data amount of the image.

The data amount reduction processing 171 is processing for reducing the data amount of an image by compressing the data of the image, for example. Thus, the image attached to the e-mail can be set to a data amount not exceeding a preset data amount.

(Transmission of E-mail for data communication apparatus)

Next, a process of attaching the read image to an email and transmitting the image in the data communication apparatus 10 will be described with reference to a flowchart.

Fig. 2 is a flowchart showing a processing procedure of attaching an image to an email and transmitting the image in the data communication apparatus according to the first embodiment.

In the data communication device 10, when the read image is transmitted by attaching it to an email, as shown in fig. 2, the image of the mth document to be read is "m", the nth email to be transmitted is "n", m is 1, and n is 1 (step S101), and the image reading unit 110 starts reading the document and reads all the documents at high resolution (step S103).

Here, after the reading of all the documents is temporarily performed at the high resolution of the color in step S103, the images are converted for each image under the reading conditions set by the user in step S113, but for example, data may be acquired for all the documents under the reading conditions set by the user in step S103. In this case, the step of step S113 is not required.

The image data of all the documents read by the image reading unit 110 is temporarily stored in the storage unit 120 (step S105). At this time, the number of documents is also stored.

Then, it is determined whether or not the m-th document is equal to or less than the total number of documents (step S107). When the images of all the documents are read and all the images are attached to n electronic mails, it is determined in step S107 that the mth document is not equal to or less than the total number of documents, and the n electronic mails to which the images are attached are transmitted to a destination set as a transmission destination (step S111), and the transmission process of the electronic mails is terminated.

On the other hand, when it is determined in step S107 that the mth document is not more than the total number of documents, the image of the mth document is selected (step S112). Then, the data amount control unit 170 converts the image for the image data of high color resolution based on the reading setting set by the user (step S113). Then, the image data amount determination unit 150 determines whether or not the data amount of the mth image after conversion exceeds a preset data amount (step S115).

In step S115, when it is determined that the data amount of the mth image after conversion exceeds the preset data amount, the data amount control unit 170 changes the setting value of the data amount reduction processing, converts the image, and reduces the data amount (step S117). When the data amount of the image is equal to or larger than the upper limit of the data amount set in advance, the data amount reduction processing in step S117 is repeated until the set value is changed to be equal to or smaller than the upper limit. In the data size reduction processing, it is desirable that the compression rate is prioritized as the priority of the reduction processing, and then the resolution and the color mode are ordered.

On the other hand, when it is determined in step S115 that the data amount of the converted image does not exceed the preset data amount, even if an image is added to the nth email, it is determined whether or not the total file size including the added images is equal to or less than the preset value (step S121).

In step S121, when it is determined that the total file size including the images to be attached is equal to or less than the preset value even if the image is added to the nth email, the image is attached to the nth email (step S125).

Then, the process proceeds to step S107, where m is m +1 (step S127).

On the other hand, in step S121, even if an image is added to the nth email, if it is determined that the total file size including the added image is not equal to or less than the preset value, the nth email is set to n +1 (step S123), the process proceeds to step S125, and the process proceeds to step S127 and step S107.

In this manner, the process of selecting the next image and attaching to the next email is repeated.

In the first embodiment, the image reading process by the image reading unit 110 is continuously performed, and thereafter, an additional image is selected to determine the data amount of the image.

(for attachment of image to email)

Next, a case where a plurality of images are attached to an email and transmitted in the data communication apparatus 10 according to the first embodiment will be described with reference to the drawings.

Fig. 3 is an explanatory diagram showing a configuration in which an image is attached to an email by the data communication apparatus according to the first embodiment.

In the flowchart of fig. 2, since the file size of an image under the reading condition set by the user is not determined when reading data of a high-resolution color document in step S103, a case where all images are converted under the reading condition set by the user in step S113 or a case where an image is read under the reading condition set by the user in step S103 will be described.

In the first embodiment, as shown in fig. 3, four images A, B, C, D are read for each page by the image reading unit 110.

The images A, B, C, D are each subjected to data amount detection by the image data detection unit 140. The data amount of the image A, B, C, D is stored in the storage unit 120 as the read image information 121.

As shown in fig. 3, for the amount of data of the image detected by the image data detection unit 140, the image a is 0.35MB, the image B is 0.35MB, the image C is 1.3MB, and the image D is 0.35 MB.

Here, in the first embodiment, the data amount of an image that can be attached to an email in the data communication apparatus 10 is set to 1 MB. If the data amount of the image attached to the e-mail does not exceed 1MB, a plurality of images can be attached to one e-mail.

When there is an image with a data amount that is set in advance in more than one image, the communication control unit 160 is configured to notify the user that there is an image with a data amount that is set in advance. Further, the file size of the image may be automatically reduced under a preset condition.

Further, the data communication apparatus 10 may reduce the file size of the image under a predetermined condition without notifying the user that there is an image exceeding a predetermined data amount.

Here, since the image C is 1.3MB and exceeds the data amount of an image that can be attached to an email, the data amount is reduced by the data amount reduction processing 171.

In the first embodiment, the data amount control unit 170 reduces the data amount by increasing the compression rate of the data of the image C as the data amount reduction process 171. Thus, as shown in fig. 3, the data amount of image C is changed from 1.3MB to 0.4MB, and can be smaller than the data amount (1MB) of an image that can be attached to an email.

In the case where four images, i.e., image A, B, C, D arranged in the order of A, B, C, D, are attached to an email, as shown in fig. 3, for example, image a (0.35MB) and image B (0.35MB) that are not subjected to reduction processing may be attached to first email 01M, and image C1(0.4MB) that is subjected to reduction processing of image C and image D (0.35MB) that is not subjected to reduction processing may be attached to one email in second email 02M.

Further, image C1(0.4MB) subjected to the reduction processing and image D (0.35MB) not subjected to the reduction processing may be attached to each email.

In the first embodiment, the image C1 subjected to the reduction processing and the image D in the subsequent order are attached to one email, but for example, in the case where the data amount of the image attachable to the email is set to 1.5MB and is smaller than the data amount of the image attachable even when the image is merged with the image of the email to which the previous image is attached, the image C1 may be attached to the email to which the previous image is attached.

In addition, for a combination of a plurality of images attached to one email, a combination of images with the smallest number of transmitted emails may be used regardless of the order of images.

In this way, in the case where there is an image exceeding the data amount of the image that can be attached to the email out of the four images of the image A, B, C, D, the data amount can be reduced by performing the data amount reduction processing, and the image can be transmitted by two or three emails. Also, by compressing the data of the four images of the image A, B, C, D, it is possible to collectively add images to a smaller number of electronic mails.

In addition, when the data reduction processing is performed on the attached image, the subject of the reduction processing on the data of the image may be marked for the email.

In addition, when a plurality of images are attached to one email and transmitted, a main subject of attaching a plurality of images may be marked in the body of the email.

Further, a character string for specifying the order of the plurality of images may be included in the file name of the image attached to the electronic mail.

When there are a plurality of image-attached emails, the communication control unit 160 may sequentially transmit image-attached emails having a small character string that specifies the order of images to be attached.

In addition, when there are a plurality of electronic mails to which images are attached, information attached to the images of all the electronic mails and information attached to the images of the respective electronic mails may be marked in the mail body of all the electronic mails.

(reading mode of image)

Next, a data amount reduction process in the data communication device 10 according to the first embodiment based on the image reading mode will be specifically described with reference to the drawings.

Fig. 4 is an explanatory diagram showing an example of a setting screen displayed on the operation unit of the data communication apparatus according to the first embodiment.

As shown in fig. 4, a setting screen 101 for setting various image reading operations is displayed on a display panel 106 (see fig. 1) of an operation unit 105 of the data communication device 10 according to the first embodiment.

The setting screen 101 is provided with a setting area 1010, and the setting area 1010 displays a color mode key 1011 for setting a reading mode of an image, a resolution setting key 1012 for setting a resolution of an image, a format setting key 1013 for setting a format of an image, a reading document setting key 1014 for setting a size of a document or the like, a density setting key 1015 for setting a density of an image, and other function setting keys 1016.

When setting the data size reduction processing, the setting operation is started by selecting the color mode key 1011, the resolution setting key 1012, the format setting key 1013, the read document setting key 1014, the density setting key 1015, and the other function setting key 1016 and performing a touch operation according to the content of the data size reduction processing.

In the first embodiment, as the data amount reduction processing, the data amount reduction processing is performed by changing the image reading mode.

Fig. 5 is an explanatory diagram showing an example of an image reading mode setting screen displayed on the operation unit of the data communication apparatus according to the first embodiment.

When the image reading mode is changed, the color mode setting screen 1011a is displayed superimposed on the setting screen 101 as shown in fig. 5 by touching the color mode key 1011 of the setting screen 101 shown in fig. 4.

On the color mode setting screen 1011a, a color automatic selection key 1011a1, a full-color key 1011a2, a gradation key 1011a3, a black-and-white key 1011a4, and the like are displayed.

When the reading mode is set, the desired reading mode is set by selecting the color automatic selection key 1011a1, the full-color key 1011a2, the gradation key 1011a3, and the black and white key 1011a4 and performing a touch operation according to the conditions of the color to be read.

Then, the data amount of the image is adjusted according to the selected reading mode.

That is, the data amount of the image becomes large in the full-color mode, and becomes small in the monochrome binary mode. Therefore, by selecting any one of the full-color mode, the grayscale mode, and the monochrome binary mode according to the state of the read image, the data of the image can be appropriately reduced.

Thus, according to the first embodiment, the data communication device 10 for performing email communication includes, in a case where the data amount of an image to be added exceeds a preset upper limit size, means for reducing the data amount of the image to thereby enable the image to be added to the email and enable the email to be easily transmitted, the means including: an operation unit 105; an e-mail transmitting section 130; an image data detection unit 140; an image data amount determination unit 150 that determines whether or not the data amount of an image attached to an email exceeds a preset data amount; a communication control unit 160 capable of transmitting an email when the amount of data of an image attached to the email does not exceed a preset amount of data; and a data amount control unit 170 that performs a data amount reduction process 171 for reducing the data amount of the image when the data amount of the image attached to the e-mail exceeds a preset data amount.

In the first embodiment, the color mode setting screen 1011a is provided as the data amount reduction processing for reducing the image attached to the e-mail, and the data amount of the image is changed by changing the image reading mode, so that the data amount of the image can be reduced in advance by changing the image reading mode in accordance with the image when the image is read.

(second embodiment)

Next, a second embodiment will be described with reference to the drawings.

For convenience of explanation, the same reference numerals are given to the same components having the same functions as those of the first embodiment, and the explanation thereof is omitted.

Fig. 6 is an explanatory diagram showing an example of a resolution setting screen displayed on the operation unit of the data communication apparatus according to the second embodiment.

A feature of the second embodiment is that the data communication apparatus 10 performs data size reduction processing by changing the resolution of an image as data size reduction processing.

When the resolution of the image is changed, the resolution setting screen 1012a is displayed on the setting screen 101 as shown in fig. 6 by touching the resolution setting key 1012 of the setting screen 101 shown in fig. 4.

On the resolution setting screen 1012a, a 100 × 100dpi setting key 1012a1, a 150 × 150dpi setting key 1012a2, a 200 × 200dpi setting key 1012a3, a 300 × 300dpi setting key 1012a4, a 400 × 400dpi setting key 1012a5, a 600 × 600dpi setting key 1012a6, and the like are displayed.

When setting the resolution of an image, a desired resolution is set by selecting and touching 100 × 100dpi setting keys 1012a1, 150 × 150dpi setting keys 1012a2, 200 × 200dpi setting keys 1012a3, 300 × 300dpi setting keys 1012a4, 400 × 400dpi setting keys 1012a5, and 600 × 600dpi setting keys 1012a6 according to the degree of data size of a reduced image.

Then, the data amount of the image is adjusted according to the selected resolution.

That is, the amount of image data decreases when the resolution decreases to 200 × 200dpi and 100 × 100dpi, and increases when the resolution increases to 400 × 400dpi and 600 × 600 dpi. Therefore, the resolution can be selected according to the size of the image, and the data of the image can be reduced appropriately.

As described above, according to the second embodiment, the data communication apparatus 10 for performing email communication includes the resolution setting screen 1012a as the data amount reduction process for reducing the image attached to the email, and changes the resolution of the image to change the data amount of the image, so that the data amount of the image can be reduced according to the size of the image.
