An information processing apparatus includes a determination, first, second and third receiving, and first and second checking units, and a controller. When a determination result matches a first determination result, the first checking unit outputs a matching determination result as the final output. The second checking unit checks the first determination result against a second. The first and second determination results are respectively received by the first and second receiving units. When the first determination result matches the second, the second checking unit outputs the matching determination result as the final output. When the input information is received, the controller operates the determination, first receiving, and first checking units. When it is determined that the determination result does not match the first determination result, the controller operates selectively one of a unit set and the third receiving unit. The unit set is constituted by the second receiving and checking units.

Images are to be efficiently and easily encoded while suppressing block distortion and pseudo-contour generation. A quantization characteristics determining unit receives pixel values from a pixel value input unit, measures the length S of the consecutive occurrence of the same pixel values in connection with a pixel to be encoded and the pixel value differences D, and determines quantization characteristics n with reference to the result of sensory evaluation. A quantization/inverse quantization unit quantizes pixel values to be inputted with the quantization characteristics n, and further inverse quantizes them to reduce the number of gray-scale levels. The output pixel values of the quantization/inverse quantization unit are encoded and outputted by an entropy encoding unit.

In a tandem-type full color printer, to print monochromatic image data the resolution of which is high and the processing load of which is high at high speed and at a low cost, the operation of each component is required as follows. If a monochromatic image is printed, MB images acquired by dividing the monochromatic image by an image processor are sequentially sent to the respective image compressors for YMCK. Four image compressors are operated in parallel and the compressed data of MB images is stored in an image storage. After the data of all MB images required for an output image is stored, an MB image controller operates the respective image decompressors for YMCK in parallel and sends the stored data to the image decompressors. The decompressed MB images are coupled to one image data in an image coupler and are sent to a print unit. The MB image controller enhances process speed for carrying paper in the print unit based upon a situation in which MB images are decoded by amount in which the processing speed of a monochromatic image is enhanced.

Image forming device

An image processing device that executes high speed overwriting of an input image with one or more partial images. A processing prediction unit judges whether overwriting is completed on all the partial images held in a small area buffer. If overwriting is completed, the overwritten partial image is compressed by an encoding unit, and the coded image is stored in a compact page memory. If overwriting is not completed, the uncompressed partial image is stored in the compact page memory. The uncompressed partial image is read from the compact page memory and is fed back to the overwriting unit through an output switch unit. The coded image stored in the compact page memory is sent to a decoding unit through the output switch unit, and is decoded to be outputted as an output image.
