摘要： PROBLEM TO BE SOLVED: To carry out an overlap removal process without increasing an intermediate code generation time in an image processing apparatus which processes images with the use of a band buffer technique.
SOLUTION: An intermediate code-generating part 10 converts for every band, data of each of objects included in a PDL showing a source image to an intermediate code and lets the code held by an intermediate code-holding part 20. When an integrated data amount of the intermediate codes held by the intermediate code-holding part 20 exceeds a predetermined amount, a rendering part 40 generates processed raster data having overlapping parts of objects removed and stores the data to a band buffer 50. Then, for bands of parts developed to the processed raster data, the intermediate codes held by the intermediate code-holding part 20 of objects excluding the objects developed to the processed raster data are read out, and the processed raster data stored into the band buffer 50 are read out, thereby generating band raster data.

摘要： PROBLEM TO BE SOLVED: To solve the problem that, when an image is decided to be a character image, if the image is quantized by using a character image quantization step with a small quantization step size, a code quantity after encoding exceeds a maximum code quantity and a code cut-off process is necessary to ensure the maximum code quantity and, as a result, the quality of the image is deteriorated. SOLUTION: An orthogonal transformation is applied to an input image by an orthogonal transformation unit 11, and the input image is quantized by a quantization unit 12 by using a quantization step size in a quantization table. The quantization factors are rearranged into the single dimensional arrangement by a one-dimensional arrangement unit 14 and then coded into variable long codes. At that time, variable long code table 17 corresponding to respective symbols are selected by a Huffman table selection unit 16 and, by using the variable long code tables 17, the quantization factors arranged into the one-dimensional arrangement are coded into variable length codes according to the respective symbols.

摘要： PROBLEM TO BE SOLVED: To provide image coding decoding method adopting the variable length coding system where coding is cancelled without causing image quality deterioration. SOLUTION: In the process of Huffman coding, an in-block Huffman code quantity (block code quantity) is counted and when the block code quantity exceeds a preset code quantity, a cancellation instruction is asserted to forcibly cancel Huffman coding processing and an end of block code EOBt is set to an end of block code data. In the process of Huffman decoding, cancellation f coding is detected by finding out the EOBt in a data stream. Since a high frequency component is lost in a pixel block where coding s cancelled, prescribed compensation processing is applied to recover an unsharpened edge.

摘要： PROBLEM TO BE SOLVED: To realize efficient data transfer wherein a processing time of a transaction of one-time data transfer is reduced.
SOLUTION: When each device transferring data between the device and another device via a bus functions as a target device 200, a pre-execution status showing whether the data transfer requested by a transfer request received from a master device 100 can be certainly executed or not is outputted. When functioning as the master device 100, the transfer request is outputted. Thereafter, only when receiving the pre-execution status showing that the data transfer cannot be certainly executed is received from the target device 200, the transfer request is stored in its own memory, and the transfer request is newly outputted to the target device 200.
