Abstract
The present invention provides an image processing device, an image processing method, and a recording medium that supply the intermediate code image data generated for each band to the hardware rendering mechanism at high speed and enhance the efficiency of a memory in use. In the image processing device, a host processing unit receives and interprets incoming PDL data, creates intermediate code image data for each band, and supplies it to an intermediate code image data holding block management unit. The intermediate code image data holding block management unit reserves intermediate code image data holding areas on the memory, and stores intermediate code image data holding blocks and management information in the areas with continuous addresses. The management information is rewritten into descriptors, which are supplied to a DMA controller, and the intermediate code image data is sequentially transferred to a rendering unit by the chained DMA transfer system. And, raster-expanded bit map data in the rendering unit is supplied to band buffers, which is delivered to the output device under the control of a band buffer read/write controller.
