Display device system and method for adaptively enhancing image quality

A method for adaptively enhancing an image quality, comprising:

• acquiring an original image, and performing iterative detail enhancement processing on the original image by utilizing at least one filter function comprising iteratively-updated filter parameters, which specifically comprises:
• for an input image on which the detail enhancement processing is to be performed, extracting feature information of an ith iteration from the input image by utilizing at least one filter function comprising filter parameters subjected to an ith iterative update, and obtaining a detail-enhanced image of the ith iteration by performing the detail enhancement processing of the ith iteration on the input image based on the feature information of the ith iteration, wherein the input image comprises an image associated with the original image, and i is an integer greater than or equal to 1;
• in a case that a difference between a quality evaluation score of the input image and a quality evaluation score of the detail-enhanced image of the ith iteration satisfies an iteration condition, obtaining filter parameters of an (i+1)th iteration by updating the filter parameters of the ith iteration, and continuing to perform the detail enhancement processing on the input image by utilizing at least one filter function comprising the filter parameters of the (i+1)th iteration, until a difference between the quality evaluation score of the input image and a quality evaluation score of a detail-enhanced image of the (i+1)th iteration satisfies the iteration condition;
• and
• displaying a detail-enhanced image of a last iteration.
