The invention provides an image processing method, which comprises the following steps: under the condition that 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 in a first window; if the exposure signal receiving position of the image sensor is not in the first window, performing delay processing on the exposure signal to enable the exposure signal to be in the second window; determining the position of a brightness abnormal line corresponding to the exposure signal in the image based on the position of the second window and the first line spacing; correcting the average brightness value of the row with the abnormal brightness; wherein the first window is located on an image line corresponding to a line synchronization signal output by the image sensor; the difference between the average brightness value of the brightness abnormal line and the average brightness value of other lines in the image is greater than or equal to a first brightness threshold value; the invention further provides an image processing device, electronic equipment and a storage medium. According to the invention, the average brightness value of the abnormal brightness lines in the image can be corrected.
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...
