Embodiments of the present invention provide a strong light suppression method and device based on intelligent analysis, which are suitable for video processing systems. The method includes: collecting the image output by the source video; detecting and predicting the strong light area of the source video image; suppressing the strong light area of the video; optimizing the video image; and outputting the optimized video image. The invention intelligently analyzes the source video, optimizes the strong light area in the video such as the strong light suppression operation, proposes a processing method for the video strong light area, realizes the strong light suppression of the video strong light area, and improves the video quality. quality, which solves the problem that the gain multiple and exposure time cannot be adjusted for different areas of the video in the prior art.
Description
technical field [0001] The invention relates to the field of video processing, in particular to a strong light suppression method and device. Background technique [0002] A sensor is a detection device that usually collects the measured information in a certain area in a dense array, and can transform the collected information into electrical signals or other required forms of information output according to certain rules to meet the needs of information. Transmission, processing, storage, display, recording and control requirements. Existing sensors cannot adjust parameters such as gain multiples and exposure time for different acquisition areas, that is, signal acquisition such as strong light suppression cannot be performed on specific areas. Moreover, in the prior art, the sensor, the image information processing device and the intelligent analysis module are independent of each other, and it is impossible to carry out cooperative processing on a certain problem (such ...
