Abstract: Disclosed are an LED drive circuit, a data processing method and apparatus, and a storage medium. The LED drive circuit comprises a plurality of LED driver chips and a controller, wherein the plurality of LED driver chips respectively comprise a plurality of data input pins and a plurality of data output pins; the controller is connected to the plurality of LED driver chips and configured to send a plurality of paths of display data to the plurality of LED driver chips. The present disclosure solves the technical problem in the related art that the data backup of the whole video card is affected when a certain chip in the video card fails due to the fact that the video card is used as a minimum unit during data backup.

Abstract: Disclosed in the present disclosure are a method and device for processing an image, a nonvolatile storage, and a computer apparatus. The method includes: acquiring an initial color value corresponding to each of pixel points; determining an adjacent pixel point corresponding to each of pixel points in an arrangement sequence; adjusting an initial color value corresponding to the adjacent pixel point, and obtaining a new color value corresponding to each of pixel points; selecting two adjacent color values that are close to the new color value corresponding to each of pixel points from color values corresponding to a target color depth; and sequentially reading the two adjacent color values corresponding to each of pixel points and displaying a target image. The present disclosure solves a technical problem of a poor image display effect caused by color distortion of an image when a color depth of the image is adjusted.
