The CMOS (Complementary Metal-Oxide-Semiconductor), known as CMOS in chinese science, is an important chip in computer systems and stores the most basic data for system booting. The CMOS manufacturing technology is not different from that of a common computer chip, and mainly utilizes a semiconductor made of two elements, namely silicon and germanium, so that N (negatively charged) and P (positively charged) semiconductors coexist on the CMOS, and the current generated by the two complementary effects can be recorded and interpreted as an image by a processing chip. CMOS has later been processed to also serve as an image sensor in digital photography. For portable applications independent of the power grid, CMOS technology, which is known for its low power consumption characteristics, has a clear advantage: CMOS image sensors are designed for 5V and 3.3V supply voltages. The CCD chip requires a power supply voltage of about 12V, and therefore a voltage converter has to be employed, resulting in an increase in power consumption. Integrating control and system functions into a CMOS sensor would provide another benefit in terms of overall power consumption: he removes all external connection lines to other semiconductor elements. Drivers with their high power consumption have been abandoned today because the energy consumed to communicate inside the chip is much lower than with external implementations through a PCB or substrate.

Aiming at the technical problem that a security mechanism in a bus is lagged behind in the prior art, the bus adopts warning modes of alarming and early warning at different degrees by carrying out customized image detection on the flame size in the bus; the method comprises the steps of extracting a preliminary target contour of an image, obtaining a distribution area where a target of the image is located and a non-classified area without the target, implementing a differential image segmentation mode, and adjusting the size of a threshold value for stripping a background of each obtained sub-image based on the width of each dynamic range of each obtained sub-image, so that directional segmentation of a foreground image is realized; on the basis of analyzing the content of the output image of the CMOS sensing equipment, identifying whether the CMOS sensing equipment leaves a preset position or not, and accordingly ensuring the validity of the output image of the CMOS sensing equipment; on the basis of carrying out frequency band analysis on the image content, corresponding edge enhancement processing is carried out on the detail component based on the signal-to-noise ratio of the whole image, and waste of operation resources is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
