Abstract

The invention discloses an OSD control module, which comprises a central processing unit, an OSD menu data memory cell and an OSD control program memory cell. The data of a palette is stored in the OSD menu data memory cell. The central processing unit executes the program which is stored in the OSD control program memory cell to process the data in the OSD menu data memory cell to generate menu graphic data on a screen. The data of the palette includes component values of each color in red, green and blue which are three primary colors. The OSD control program memory cell stores instructionswith component values of each color in red, green, and blue in a transposing palette. When executing the instruction, the central processing unit can transpose component values of each color in red, green and blue which are three primary colors in the palette so that a new palette is generated thereby. The OSD control module provided by the invention allows an OSD menu displayed on the screen to present diversified colors. The invention further provides a method for setting colors of the OSD menu.

Description

【Technical field】 [0001] The invention relates to an On Screen Display (OSD) control module, in particular to a method for setting the color of an OSD menu. 【Background technique】 [0002] Early electronic display devices (such as TVs, monitors, etc.) generally use the buttons set on the electronic display device itself to adjust its various display parameters (such as brightness, chromaticity, contrast, etc.), and the screen does not The changes of various parameters are not shown, and the result of adjustment is judged entirely according to the feeling of human eyes. [0003] With the advancement of technology, manufacturers have developed display devices with OSD functions, that is, a menu interface that displays various adjustable parameters and their values ​​on the screen of the display device, and users can enter the menu through the buttons set on the display device. Interface, adjust various parameters displayed on the menu interface through this button, and the us...
