Description

[Technical field]

[0001] The utility model relates to the technical field of correction control circuits, in particular to a correction control circuit for nighttime image light radiation at a stable mapping point with outstanding application effect. [Background Technology]

[0002] With respect to current image processing technology, it is often difficult to detect the direction of an image when the image is oriented incorrectly, resulting in a lack of stability in the specific presentation of the image. In particular, a camera or video camera can only capture the color information of image pixels, but not the direction information associated with the image. In this case, if an image is taken in the wrong direction or the image is oriented incorrectly during transmission, the image direction can usually only be directly identified to rotate the image to the correct direction.

[0003] For example, the invention patent with application number CN202210186162.3 and patent name "Image Correction Method and Image Correction Device" specifically discloses an image correction method and an image correction device. The method includes: identifying at least one object in the first image to define the object block image of the object; using a direction calculation model to calculate the object direction of the object in the object block image, the object direction is the deflection angle relative to the reference axis on the two-dimensional coordinate plane, and the deflection angle is any angle between 0 degrees and 360 degrees; and generating image deflection information of the first image based on the deflection angle, and using the image deflection information to correct the first image to the second image. In this way, image direction recognition and image direction correction with excellent accuracy can be provided.

[0004] Although the above-mentioned technical solutions of the existing designs have improved the stability of the image to a certain extent and achieved image correction, the degree of correction is still insufficient, which affects the final presentation of the image and the viewing experience.

[0005] Based on this, further improvements and enhancements are needed in terms of specific circuit connections and component settings. [Contents of the utility model]
