Image drawing device and image drawing method

Abstract

The present invention provides a figure dividing unit sequentially generates, on the basis of sequentially input figure data, plural processing unit data respectively representing portions corresponding to plural partial areas constituting an image drawing area of a figure represented by the figure data. Drawing processing units each correspond to at least one of the plural partial areas, and perform, using the processing unit data, drawing processing on the corresponding partial areas independently of one another. A processing assignment unit sequentially determines which one of the drawing processing units should process the processing unit data, on the basis of drawing position information contained in the processing unit data that are sequentially generated by the figure dividing unit.

Description

technical field [0001] The present invention relates to an image drawing device and an image drawing method, and more particularly, to a technique for increasing image drawing speed. Background technique [0002] An image drawing device of 3-D graphics (graphics) etc. draws a drawing subject image (image) by treating the drawing subject image (image) as a collection of a plurality of figures (for example, triangles) and performing drawing processing for each figure . In order to improve rendering performance, these image rendering devices generally employ a pipeline processing architecture in which a plurality of processes (stages) that can be performed independently of each other are performed simultaneously. Image drawing speed can also be increased by having multiple image drawing devices work in parallel. [0003] For example, a technique for increasing the processing speed of an image processing system (image processing apparatus) is disclosed in Japanese Unexamined P...
