Abstract

The embodiment of the invention provides a backlight control method and device, equipment and a storage medium, and belongs to the technical field of exposure imaging, and the method comprises the steps: determining an image exposure mode and a target light-emitting sequence of a plurality of light-emitting units in response to a shooting instruction; wherein the image exposure mode is a line-by-line exposure mode, and the target light-emitting sequence is different from the arrangement sequence of the plurality of light-emitting units; and performing image exposure according to the image exposure mode, and controlling the plurality of light emitting units to emit light according to the target light emitting sequence so as to realize image shooting. Moire patterns do not appear in the image, and the quality of the image is improved.

Description

technical field [0001] The present application relates to the technical field of exposure imaging, and in particular to a backlight control method, device, equipment and storage medium. Background technique [0002] The camera device may include a rolling shutter and a backlight source. The rolling shutter is a mechanism used by the camera equipment to control the effective exposure time of the photosensitive film. The backlight source can illuminate the imaging target area of ​​the camera equipment. [0003] During image capture, the rolling shutter can scan the sensor line by line for exposure until all pixels are exposed. During the exposure process, the backlight light source can illuminate the imaging target area line by line. If the frame rate of the light emitting from the backlight source is inconsistent with the exposure frame rate of the rolling shutter, optical interference will occur between the backlight source and the rolling shutter, resulting in moiré in th...
