Abstract

The invention discloses an image contrast adjustment method, a display device and a storage medium, and the method comprises the steps: obtaining a contrast added value of an image, and determining anoriginal contrast adjustment curve according to the contrast added value; obtaining a correction angle, and determining a correction curve according to the correction angle; correcting the original contrast adjustment curve according to the correction curve to obtain a target contrast adjustment curve; adjusting the image contrast according to the target contrast adjustment curve, wherein the slope of the correction curve is smaller than that of the original contrast adjustment curve. An original contrast adjustment curve and a correction curve are determined according to a contrast added value; the original contrast adjustment curve is corrected by using a correction curve of which the slope is smaller than that of the original contrast adjustment curve, the image contrast is adjusted byusing the corrected original contrast adjustment curve, the brightness of the high-gray-scale part of the image is lowered, and the phenomenon of high-gray-scale whitening of the image is eliminatedwhile improving the image contrast.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image contrast adjustment method, a display device and a storage medium. Background technique [0002] Image digital processing technology is a technology that digitizes the image and performs various processing. At present, various technologies for image quality processing, such as saturation adjustment, noise reduction processing, contrast adjustment, edge enhancement, etc., can play a great role in improving and enhancing the image quality. [0003] The essence of contrast adjustment is to expand (or compress) the original value range of image pixels to another value range, so as to enhance (or reduce) the pixel difference, and finally achieve the goal that the human eye can clearly distinguish the image difference. The existing contrast adjustment method is to increase the brightness slope of the picture, and this method will cause high grayscale inversion phenom...
