Abstract
A system to render a color image using a binarized image representing the color image and a hierarchical tree structure representing the color image, the hierarchical tree structure including nodes representing respective blocks of image data within the color image, the nodes containing color information for respective blocks. The system includes a defining step to define, in a memory, a color image rendering area corresponding to a block of image data in the color image, an obtaining step to obtain foreground color information from a node corresponding to the block of image data, a detecting step to detect black pixel locations in the binarized image within an area of the binarized image corresponding to the block of image data, and an assigning step to assign the foreground color to pixels at locations in the color image rendering area corresponding to the detected black pixel locations.
