The invention belongs to the technical field of image processing, and provides an image processing device and an image processing method. According to the image processing device, large-pixel photosensitive signals of an output image of an input module sequentially pass through a first analog storage module for being stored and a first amplifying module for being amplified and processed, and then first optimized photosensitive signals are outputted; small-pixel photosensitive signals of an output image of the input module sequentially pass through a second analog storage module for being stored and a second amplifying module for being amplified and processed, and then second optimized photosensitive signals are outputted; and a synthesizing module synthesizes the first optimized photosensitive signals and the second optimized photosensitive signals, and wide-dynamic image signals are outputted through an output module. Double channels are adopted to carry out WDR (Wide Dynamic Range) synthesis on large-pixel and small-pixel photosensitive signals, and a bottleneck of a photographing speed for reduced frame processing does not exist; and when the same image is processed, no time delay exists, and the problems that time delay exists in the existing image synthesis technology, the frame rate is reduced, and the image is blurred as smear exists when a moving target is photographed can be solved.
Description
Technical field [0001] The invention belongs to the technical field of image processing, and particularly relates to an image processing device and method. Background technique [0002] In recent years, the existing single-chip wide dynamic range (hereinafter referred to as WDR, Wide Dynamic Range) technology usually uses DSP (Digital Signal Processing, digital signal processing) to synthesize multiple frames of images with different exposure times, which is used for continuous synthesis. Frame images usually have a large delay, so when shooting moving targets, there will be a problem of smear caused by image blur. Secondly, the synthesized WDR image will reduce the final output frame rate to half or less of the original frame rate. When shooting fast-moving targets, the frame rate will be a bottleneck. [0003] Therefore, the existing image synthesis technology has the problems of time delay, reduced frame rate, and blurring of images caused by smear when shooting moving targets....
