Embodiment Construction
[0053] In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.
[0054] figure 1 A schematic diagram of an image showing rows with abnormal brightness.
[0055] Such as figure 1 As shown, in some global exposure image sensors, when the image data is being read from the image sensor, the exposure signal is received, the image sensor is controlled to perform a new exposure, and the image sensor receives the exposure sig...

The present application provides an image processing method, including: when an image sensor outputs image data, if an exposure signal is received, determining whether the position where the image sensor receives the exposure signal is within a first window; if the image sensor receives If the position of the exposure signal is not within the first window, delay processing is performed on the exposure signal so that the exposure signal is within the second window; based on the position of the second window and the first line spacing, determine the position of the abnormal brightness line corresponding to the exposure signal in the image Position; Correct the average brightness value of the abnormal brightness row; Wherein, the first window is located on the image row corresponding to the line synchronization signal output by the image sensor; The difference between the average brightness value of the abnormal brightness row and the average brightness value of other rows in the image is greater than or equal to the first brightness threshold; the present application also provides an image processing device, electronic equipment and storage medium. The application can realize the correction of the average luminance value of the lines with abnormal luminance in the image.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to an image processing method, device, electronic equipment and storage medium. Background technique [0002] In the process of reading image data from the image sensor, if the image sensor performs a new exposure, then this exposure will cause abnormalities in the image data being read, which is manifested by abnormal brightness lines in the image; therefore, how to correct Due to the exposure of the image sensor during the process of reading the image, the abnormal line of brightness in the image is a technical problem that needs to be solved. Contents of the invention [0003] The present application provides an image processing method, device, electronic equipment and storage medium to at least solve the above technical problems existing in the prior art. [0004] The first aspect of the present application provides an image processing method, including...
