Abstract: A motion of an image in a block is detected with respect to image data D1, a coding mode to be applied thereto is selected among a plurality of prepared coding modes, and motion compensation is performed for the image data (Step S101). Then, an orthogonal transform coefficient D6 and coding mode information D3 undergo variable-length coding to generate coded data D7 (Step S103). Subsequently, in the variable-length coding of the coding mode information, a probability table for use in arithmetic coding is switched for each of binarization codes included in a binarization pattern of the coding mode information with reference to a coding mode selected in a block adjacent to the block. Thus, the image coding method, image decoding method, image coding apparatus, image decoding apparatus, program, computer data signal, and image transmission system, which are capable of enhancing efficiency of data compression for coding mode information multiplexed on coded data, are realized.

Abstract: This invention is an MPEG decoding apparatus (10) for decoding a compression-coded image data stream, the apparatus including a motion compensation circuit (15) and error map table holding means (19) for holding an error map table with respect to a decoded frame to be referred to in performing motion compensation. When the error map table is referred to and an error block is found to be included in a reference area, or when dynamic image data of a decoding target block is broken, the motion compensation circuit (15) performs error conceal processing to interpolate a pixel in the decoding target block with a pixel in the decoded frame and output the resulting data. The motion compensation circuit (15) generates an error map table showing the error-concealed block as an error block and stores this error map table. This MPEG decoding apparatus (10) restrains propagation of an error due to the error conceal processing and reduces deterioration in image quality.

Abstract: A system and method for decoding an MPEG video bitstream comprising several macroblocks of data is disclosed. The system comprises a macroblock core (MBCORE) which processes video bitstream data and computes discrete cosine transform data corresponding to the processed video bitstream, and a parser which parses the video bitstream macroblocks into multiple data blocks used in subsequent stages of decoding. The system further includes a transformation/motion compensation core (TMCCORE) which is divided into multiple stages. The TMCCORE includes an IDCT first stage, an intermediate memory (transpose RAM), and an IDCT second stage. The IDCT first stage passes data to memory and the IDCT second stage receives data from memory. The IDCT first stage has the ability to operate on a first data block while the second stage simultaneously operates on a second data block. The TMCCORE receives the discrete cosine transform data from the MBCORE and calculates and reconstructs a frame therefrom using motion compensation.

Abstract: An image reading method which can achieve highly accurate image reading with no color balance lost regardless of the type of recording media, that is, whether a film is a negative film or a reversal film, and thus is able to obtain in a stable manner a reproduced image of higher quality having excellent color balance and density balance. A reading light beam is irradiated on a transparent-type original, the transmitted light of the transparent-type original is separated into the three primary colors and is read by means of an photoelectric transducer device. If the transparent-type original is a negative film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made respectively in the three primary colors independently of one another and, if the transparent-type original is a reversal film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made uniformly in all of the three primary colors.

Abstract: A system and method is disclosed for compressing and decompressing composite video signals. In one type of operation a composite video signal (e.g., an NTSC signal) is sampled and the samples compressed into 3 or 5 bit composite values, depending on the system mode (PREVIEW or HIGHRES). For the HIGHRES mode the compressed composite values are written into a RAM for at least the four fields associated with the most recent two frames. As needed, the compressed values are transferred to a decoding engine implemented in software. The decoding engine, without any need for phase locked loop circuitry, decompresses the data, and decodes the decompressed digital composite values into YUV and/or RGB values. When the system is in the 5-bit mode, the decoding engine scans and compares all four fields to detect the existence of motion in the image, which could blur the captured image. In regions with motion only a single field of data is used as the source of the image data for those regions.
