METHOD FOR DISPLAYING ON-SCREEN DISPLAY

摘要

A method for displaying an on-screen display (OSD) is disclosed. An OSD with a first and second icons superimposed thereon is firstly rendered with a first color palette. The first and second icons are overlapped. The first icon is rendered with a second color palette and superposed over the originally displayed first icon. The second color palette is substantially similar to the first color palette but replaces an indexed color of the first color palette corresponding to the background color of the originally displayed first icon with a transparent color and another indexed color of the first color palette corresponding to the foreground color of the originally displayed first icon with a non-color color. The second icon is rendered with the first color palette and superposed over the originally displayed second icon.
