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.
