Display image color self-adaptation method and device for head up displayer

Abstract

The invention provides a display image color self-adaptation method and device for a head up displayer. The display image color self-adaptation method comprises the steps that firstly, according to a collected image of a color sampling area, color data of specific sampling points of the color sampling area is obtained, the arithmetic mean value or the geometric mean value of the color data of all the specific sampling points is calculated, and the obtained arithmetic mean value or the obtained geometric mean value serves as the color data of the color sampling area; secondly, complementary color data is calculated according to the color data; thirdly, the color of an output image is set as the color corresponding to the complementary color data or a color closest to the complementary color data is selected from preset colors to serve as the color of the output image. By means of the display image color self-adaptation method and device for the head up displayer, the recognition degree of HUD product project information is improved, the HUD auxiliary driving safety capability is improved, and the potential danger of traffic accidents is reduced.

Description

technical field [0001] The invention relates to a display image color adaptive method and device for a head-up display. Background technique [0002] Head Up Display (HUD), also known as head-up display, can virtual image and project vehicle status, navigation, vehicle fault diagnosis and other related information to the front of the car, keeping the driver's eyes on the road ahead. Thereby avoiding the potential danger caused by the driver looking down or sideways to observe the information on the instrument or the navigator, so it is more and more favored by the market and consumers. [0003] At present, the HUD products on the market set specific colors for the graphic element content of the projected image when designing the user interface (hereinafter referred to as UI). Although some brands of HUD products provide the function of UI replacement, the graphics in the same set of UI The color of the elements cannot be changed dynamically, which will cause the image proje...

AI Technical Summary

Problems solved by technology

[0003] At present, the HUD products on the market set specific colors for the graphic element content of the projected image when designing the user interface (hereinafter referred to as UI). Although some brands of HUD products provide the function of UI replacement, the graphics in the same set of UI The color of the element cannot be changed dynamically, which will cause the image projected by the HUD to be inconvenient to be recognized by the driver in some cases, which will lead to potential danger

[0004] For example, if the graphic elements of the UI design are blue and the color of the vehicle ahead is also blue, the graphic elements projected by the HUD will be difficult to recognize clearly; if the graphic colors of the UI design are other colors, the same unrecognized problems

If the image and graphic element information projected by the HUD cannot be clearly and effectively recognized, the function of the HUD to assist driving safety cannot be fully realized. occupants take their eyes off the road and cause potential hazards
