    摘要: A display control apparatus for a display device, capable of updating a display state for a display element subjected to a change in display updating, includes a display data memory for storing display data, and a display controller capable of sequentially reading out the display data stored in the memory and transferring the readout display data to the display device at a predetermined period and capable of performing a partial rewrite operation of the display data stored in the memory. A rewrite detector detects an address for accessing the display data memory to cause the display controller to perform the partial rewrite operation, a specific pattern rewrite detector detects an address of display data subjected to a rewrite operation of the specific pattern and stored in the display data memory, and a rewrite address generator preferentially transfers the address detected by the specific pattern rewrite detector over the address detected by the rewrite detector, reads out the display data from the display data memory at the transferred address, and transfers the readout data to the display device.

    摘要: An image processing method and system is provided wherein a plurality of processors perform a conversion process from a page description language format of data into raster image data, and a printing engine which continuously receives color image data having at least three color components in page unit and prints the at least three color components of color image data on a recording medium in parallel at a constant speed. A page description language format of data is received that includes at least two of the at least three color components as at least an object constituting the page description format data, the page description language format of data is analyzed and, based on the analysis, each color component data of the object in the received data is assigned to each processor such that the plurality of processors perform the conversion processes of the at least two of the at least three color components in parallel thereby producing raster image data of each color component from the plurality of processors to the printing engine in parallel.
