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.

Efficient rasterization system and method

A segmented imaging sensor having plural output pipelines in correspondence to the number of segments. Discontinuities between segments of the electronic imaging sensor are reduced by providing duplicated pixel values for pixels in an overlap region between segments, and by providing the duplicated pixels to processors that process the output from pipelines whose segments border on the overlap region.

Reducing discontinuities in segmented imaging sensors

Color-correcting data from a segmented imaging sensor having plural sensor segments. The data is stored in plural segment memories each of which corresponds to one of the sensor segments, and each segment memory stores overlap data and non-overlap data from the corresponding sensor segment. The overlap data in each segment memory includes boundary data from a boundary region of the sensor segment for which color correction is performed based at least in part on data from a segment memory for an adjacent sensor segment. The overlap data further includes other data from the segment memory used to color-correct the boundary data. According to the invention, overlap data from at least a first half of the segment memories is loaded into a memory buffer. Alternatively, boundary data from all of the segment memories and non-boundary overlap data from a first half of the segment memories are loaded into the memory buffer, or boundary data from all of the segment memories is loaded into the memory buffer. Boundary and/or overlap data from the memory buffer is combined with data from some or all of the segment memories. Color correction is performed of boundary data based on the combined data, and color correction is performed of non-boundary data for each of the segment memories.

Reducing discontinuities in segmented SSAs

A decrypting compiler that accepts encrypted source code from a software manufacturer, decrypts the encrypted source code into plain text that is not accessible outside the compiler, and compiles the decrypted source code into linkable binary objects. Because the decrypting compiler decrypts the encrypted source code such that the plain text is not accessible outside the compiler, trade secret and proprietary information from the source code is not easily learned by third-party software developers.
