Auxiliary color blindness color vision device

Abstract

The invention discloses an auxiliary color blindness color vision device which comprises a video capturing device, a video receiving circuit, a high-speed digital signal processor, a test image storage and loading interface circuit, a memory circuit, a video sending circuit and a display lens. The high-speed digital signal processor completes video source data selection, RGB three-color channel gain adjustment and brightness and contrast adjustment. According to the auxiliary color blindness color vision device, the gain of the color channels corresponding to the collected video signals is adjusted on the achromate barrier color segment, so that the achromate can distinguish the color visual information included in the color segment correctly; through digital video processing, a feasible solution is provided for assisting the achromate in distinguishing the color information correctly.

Description

technical field [0001] The invention relates to the technical field of digital video signal processing, in particular to a color-blind color vision auxiliary device for video signal processing of color-blind patients. Background technique [0002] There are two types of human visual receptors, one called rod cells and the other called cone cells. Rod cells are mainly distributed on the outer side of the retina, responsible for receiving light information in dark light conditions, and have no effect on color vision; cone cells are mainly distributed in the central groove of the retina, responsible for receiving light information in bright environments, and are also responsible for perception An integral and important part of color. There are three types of cones: long-wave, medium-wave, and short-wave, also known as red, green, and blue (type R, G, and B). Each type of cone perceives light within a certain wavelength range and transmits it to the brain to form rich and colo...

AI Technical Summary

Problems solved by technology

The method of optical correction is that color-blind patients wear glasses coated with a special film to reduce the light entering the eyes of the hypersensitive color segment to achieve the purpose of correction, but for the less sensitive color segment, optical correction is powerless

Moreover, there are different types of color blindness, and commercially produced color blind glasses cannot achieve the ideal correction effect.
