Image processing apparatus and system, electronic device and image processing method

Abstract

The invention relates to an image processing apparatus and system, an electronic device and an image processing method. The image processing apparatus comprises an obtaining module used for separatelyobtaining an exposure time of each row of pixels; a judging module used for judging whether the obtained exposure time is an integer multiple of twice of power supply frequency; an adjustment moduleused for adjusting the exposure time to the integer multiple of twice of the power supply frequency when the exposure time is a non-integer multiple of twice of the power supply frequency; and an execution module used for performing exposure according to the adjusted exposure time. By adoption of the image processing apparatus and the image processing method provided by the invention, the exposuretime is adjusted to the integer multiple of twice of the power supply frequency to effectively avoid flickering in an image processing process, thereby greatly improving the image processing performance.

Description

technical field [0001] The present invention relates to the technical field of electronic communication, in particular to an image processing device, system, electronic equipment and image processing method. Background technique [0002] Image sensors are devices that convert light signals into electrical signals, and are widely used in digital TV and visual communication markets. In the late 1960s, Bell Labs in the United States discovered the phenomenon of charge transfer through semiconductor potential wells, and proposed a new concept of solid-state imaging and a one-dimensional CCD (Charge-Coupled Device) model device. [0003] By the early 1990s, CCD technology had become popular and widely used. However, with the expansion of CCD application range, its shortcomings are gradually exposed. First of all, CCD technology chip technology is complex and cannot be compatible with standard technology. Secondly, the voltage and power consumption required by the CCD technolog...

[0014] However, the CMOS image sensor using the rolling shutter can only guarantee that the starting point of the exposure time of any pixel in each row is consistent with the exposure time, but it cannot guarantee that the starting point of the exposure time of any row is consistent. Although the exposure time is consistent, the integral energy of the exposure It is easy to produce differences, that is, the exposure of each line is different, and there is a situation of light and dark, this phenomenon is flicker (fliker)
