Abstract: A method and an image processing device for mura detection on a display are proposed. The method includes the following steps. A compressed DeMura table corresponding to the display panel is obtained. Decompression is performed on the compressed DeMura table to generate a decompressed DeMura table. Upsampling is performed on the decompressed DeMura table to generate a reconstructed DeMura table. Mura compensation is performed on the display panel based on the reconstructed DeMura table.

Abstract: A display driving apparatus including a pixel reorder circuit, an image processing circuit and a driver circuit is provided. The pixel reorder circuit is configured to reorder pixels of frame data. The frame data includes previous frame data. The image processing circuit is coupled to the pixel reorder circuit. The image processing circuit is configured to perform an image processing operation on the frame data that the pixels have been reordered. The driver circuit is coupled to the pixel reorder circuit. The driver circuit is configured to drive a display according to the previous frame data that pixels have been reordered and the current frame data. Each of the pixels of the frame data includes a first sub-pixel set and a second sub-pixel set. In addition, a display driving method is also provided.
