DRAWING DATA GENERATION DEVICE, DRAWING DATA GENERATION METHOD AND DISPLAY DEVICE

摘要

At the time each of the components is to be drawn according to the drawing orders determined by a drawing-order determination unit 12, a drawing-data generation unit 14 generates, when another component having an overlap in drawing area with the component has been searched by an overlapped-component search unit 13, drawing data for indicating drawing of an area in the drawing area of that component except for its drawing area overlapped with the other component if the drawing order of that component is earlier than the drawing order of the other component, or drawing data for indicating drawing of all drawing area of that component if the drawing order of that component is later than the drawing order of the other component.

1: A drawing data generation device, comprising:
a drawing-order determination processor that determines drawing orders of a plurality of components for forming a screen, according to a drawing rule in which, among the plurality of components, the component used for a background is firstly drawn followed by drawing so that the more the component is to be placed toward a front side of the screen, the later the component is drawn; an overlapped-component search processor that compares drawing areas of the plurality of components for forming the screen to each other, to thereby search a component having an overlap in drawing area with another component; and a drawing-data generation processor that, with respect to the components to be drawn, generates as drawing data of said component drawing data for indicating drawing of all drawing area of the component when another component having an overlap in drawing area with said component has not been searched by the overlapped-component search processor, while generating as the drawing data of said component, when another component having an overlap in drawing area with said component has been searched by the overlapped-component search processor, drawing data for indicating drawing of an area in the drawing area of said component except for its drawing area overlapped with the other component if the drawing order of said component is earlier than the drawing order of the other component, or generating as the drawing data of said component drawing data for indicating drawing of all drawing area of said component if the drawing order of said component is later than the drawing order of the other component, to generate the drawing data in a unit of said component.
