摘要： PROBLEM TO BE SOLVED: To provide an image coder and an image decoder that can surely enhance a compression ratio without deteriorating image quality only through addition of a simple circuit. SOLUTION: A DCT control section 1 of a coding section 11 converts a received image into a DCT coefficient, and a quantization section 2 quantizs an output of the control section 1. A subtractor section 13 calculates a difference between the transform coefficient after the quantization outputted from the coding section 11 and a transform coefficient after quantization of a preceding block stored in a preceding block transform coefficient storage section 12. An absolute value sum calculation section 14 calculates the total sum of absolute values of the differences calculated by the subtractor section 13. Moreover, an absolute value sum calculation section 15 calculates the total sum of absolute values of the transform coefficients after quantization of a current block. A comparator section 16 compares the absolute sums calculated by the absolute value sum calculation sections 14, 15, and a selection section 17 selects the difference calculated by the subtractor section 13 or the transform coefficient after the quantization of the current block which has a smaller absolute sum according to the comparison result.

摘要： PURPOSE: To obtain a Huffman decoder which is capable of reducing the capacity of a table and decoding a Huffman code at a high speed. CONSTITUTION: The number of bits of the code data within a shift register 3 is set to a counter 4. A code number take-out means 5 takes out the number of codes of a code number table 2 based on the value of the counter 4. By an adder 12 and a pointer register 8, the cumulative value of the number of codes is calculated. The number of codes within the number of codes register 6 and the value of an offset register 7 are added in an adder 9. The value which is twice the added value is stored in an offset register by a shift computing element 11. The added value and code data are compared by a comparator 10. When the code data is below the added value, the value of the offset register 7 is subtracted from the code data by a subtracter 15, and this value and the value of a pointer register 14 are added by an adder 16. Based on this addition result, a symbol is obtained from a symbol table 1 and the symbol is outputted.

摘要： PURPOSE:To transmit signal without an error and the fluctuation of a power source level and a ground level even when an output operates with the same timing by adding the inside logical part of an intergrated circuit IC with an output part and a level detection part and the inside logical part of the other IC with an input part at the time of connecting IC and the other IC to transmit a signal from IC to the other IC. CONSTITUTION:The level detection part 2 monitors a signal outputted from the inside logical part 1 and outputs a detection signal at the time of detecting all of the output level becomes low. Thus, the output part 3 converts the level with a system specified to make all of the outputs from the inside logical part 1 not in a low level to output it. The input part 4 decodes the signal of an inside logic 1 from the detection signal and the level-converted signal to input it to the inside logical part 5 of IC 2.

摘要： PROBLEM TO BE SOLVED: To provide an image processing apparatus and an image processing method capable of generating appropriate color component data, while maintaining the versatility of image data.
SOLUTION: A compression portion 104 compresses inputted image data and generates JPEG image data. A DMA 106 makes a memory 108 store a plurality of compressed band code data acquired by dividing these JPEG image data by RST markers, and forms a positional information table representing the position of each piece of compressed band code data. When a transfer timing of a color component comes, a DMA 112 reads compressed band code data in the memory 108 as required on the basis of the positional information table, and makes a band buffer 116 store band code data acquired by expansion of an expander 114. A print I/F 110 reads band code data in the band buffer 116 and converts the data into color component data.
