Image processing system and image processing method

Abstract

Provided are an image processing system and an image processing method. According to the image processing system of the present invention, the visual effect of an image viewed by a user with abnormal color vision can be effectively improved by means of calculating a color difference energy function value of each pixel of an input image under a plurality of groups of color ratios in a lookup table corresponding to a color vision abnormity type of the current user; taking a corresponding color ratio, when the color difference energy function value of each pixel is the maximum value, as a selected color ratio of each pixel; using the selected color ratio of each pixel and a color vision abnormity degree value of the current user to process an input RGB grayscale of each pixel so as to obtain an output brightness value of each pixel; converting the output brightness value of each pixel, and an input tone value and an input saturation value in input HSI data to obtain an output RGB grayscale of each pixel; and generating an output image.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an image processing system and an image processing method. Background technique [0002] With the development of display technology, flat panel display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Display (OLED) have high image quality, power saving, thin body and application Due to the advantages of a wide range, it is widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and has become the mainstream of display devices. [0003] Most of the existing liquid crystal display devices generally include: a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small ...

Problems solved by technology

Color blindness correction lenses are based on complementary color antagonism, and a special coating is applied on the lens to produce a cutoff wavelength. The disadvantage of this method is that additional glasses are required, and the overall brightness of the image seen by the wearer will become darker.

Compensation on the display side also uses the complementary color antagonism theory to strengthen the colors that cannot be recognized by users with abnormal color vision and weaken their complementary colors, which can alleviate the visual impairment of color weak people to a certain extent, but this method has almost no effect on color blindness.
