Problems solved by technology

The adjustment of exposure parameters is an important factor to ensure the image quality. At present, the commonly used AE adjustment method is to adjust the exposure time (Exposure Time, ET) and exposure gain (Exposure Gain, G), step by step to approach the image to the ideal exposure. , causing the current AE algorithm to generally have the problem of slow speed and low efficiency

Abstract

The invention discloses an exposure parameter determining method and apparatus, and a readable medium, and belongs to the technical field of image processing. In the method and apparatus provided by the invention, an exposure evaluation value of a current frame of image and a current exposure parameter are determined; and the exposure parameter for shooting the next frame of image is determined according to the current exposure parameter and a target exposure value of the next frame of image. As the exposure parameter for shooting the next frame of image is determined by using the exposure evaluation value of the current frame of image, the exposure parameter for shooting the current frame of image, namely, the current exposure parameter, and the target exposure value of the next frame ofimage, on one hand, the quick determination of the exposure parameter is achieved, and on the other hand, the image quality of the next frame of image shot by using the determined exposure parameter is also guaranteed.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and readable medium for determining exposure parameters. Background technique [0002] With the improvement of human living standards and industrial modernization, imaging devices (such as cameras) are increasingly used in various industries in daily life, such as consumer photography, industrial machine vision, quality inspection and automatic driving, etc. Wait. Some algorithms are built into the camera to enable the system to automatically perform feature extraction and recognition on images, such as face recognition, industrial defect detection and security monitoring, etc. At this point, image quality is the most important foundation. If the quality of the original image output by the camera is not good (such as blurry or insufficient detail), it will be difficult for the back-end system to recognize it. [0003] To solve this problem, th...
