Embodiment 1

[0020] The software implementation of the red-green color blindness display conversion device may include two parts of work: one is to use a display device driver that supports the red-green color blindness mode of use, and the other is to provide the user with the ability to switch between the normal color screen mode and the red-green color blindness mode of use. Operation interface.

[0021] Such as image 3 As shown, add components to the mobile phone setting panel of the Windows Mobile platform, and use the software switch to set whether to switch the red-green color blind mode.

[0022] The display device driver that supports the red-green color blindness usage mode adds the conversion function ConventRGBtoGray on the basis of the existing mobile phone display device driver. The conversion function will calculate the effective brightness value of each pixel in the image, and convert the brightness value by matching pixels for black and white images.

[0023] To calcula...

Embodiment 2

[0048] Such as Figure 4 As shown, a red-green color blindness mode switch 101 is set on the keypad of the color screen mobile phone to provide the user with an operation interface that can switch between the normal color screen mode and the red-green color blindness use mode.

[0049]After the switch 101 is pressed, the ConvertToGrayscale function is a conversion function. This function converts each pixel in the screen display area through a conversion formula, and the return value is output to the hardware drive device, thereby realizing the conversion from color pixels to black and white pixels.

Embodiment 3

[0051] Such as Figure 5 As shown, the ConvertToGrayscale function is a function in the new display driver that adds the red-green color blindness function. Through the software switch on the mobile phone setting panel of the Windows Mobile platform, switch whether to call the ConvertToGrayscale function is set, so that the user can easily Switch between red-green colorblind mode and normal mode.

[0052] After the software switch is clicked, the ConvertToGrayscale function is a conversion function. This function converts each pixel in the screen display area through a conversion formula, and the return value is output to the hardware drive device, thereby realizing the conversion from color pixels to black and white pixels.

Abstract

The invention provides an anerythrochloropsia display conversion method based on a color display mobile phone, and a device thereof. The device comprises an anerythrochloropsia display conversion switch used for triggering a display conversion program; a pixel conversion unit used for calculating the effective brightness value of each color pixel of color pictures in a color display area and converting the effective brightness value of each color pixel through pixel matching to generate black and white pixel value; a display drive unit which is used for converting the color picture in the color display area into a black and white picture. The method eliminates the inconvenience of anerythrochloropsia users when using the color display mobile phone and expands the social benefit and the economic benefit of the application of the color display mobile phone.

Description

technical field [0001] The present invention relates to the mobile phone terminal display technology in the field of wireless communication, in particular to a red-green color-blind display conversion method and device based on a color-screen mobile phone. Background technique [0002] According to statistics, color-blind patients account for about 8% of the world's population, and most of the mobile phones in the market are color-screen mobile phones. Color-blind users will have a lot of inconvenience when using color-screen mobile phones. [0003] Chinese patent application 200580001810.8 discloses a method and device for compensating the color in the display device of the user terminal through the network. This patent application changes the color of the user terminal such as mobile phones to provide users with insufficient color vision with the same vision as those with normal vision. Effect. The technical solutions disclosed in this invention application can be incorpo...
