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.

Embodiment Construction

[0046] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0047] Please refer to 1, the present invention provides an image processing system, including a pre-processing module 10, a ratio calculation module 20 electrically connected to the pre-processing module 10, and a look-up table electrically connected to the ratio calculation module 20 The module 30 and the post-processing module 40 are both electrically connected to the ratio calculation module 20 and the pre-processing module 10 .

[0048] The pre-processing module 10 is used to receive an input image, convert the input RGB grayscale of each pixel of the input image into input HSI data, and transmit the input RGB grayscale and input HSI data of each pixel to the post-processing module 40 and convert multiple The input HSI data of pixels is t...

Abstract

The invention provides an image processing system and an image processing method. The image processing system of the invention is characterized by calculating the 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 the color vision abnormity type of a current user; taking the corresponding color ratiowhen the color difference energy function value of each pixel is the maximum value as the selected color ratio of each pixel; processing the input RGB gray scale of each pixel by using the selected color ratio of each pixel and the color vision abnormity degree value of the current user to obtain the output brightness value of each pixel; and converting the output brightness value of each pixel,the input hue value and the input saturation value in the input HSI data to obtain the output RGB gray scale of each pixel, and generating an output image, so that the visual effect of the image watched by a user with abnormal color sense can be effectively improved.

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 ...
