    摘要: An image evaluation apparatus includes a pixel extraction unit, an intra-pair difference calculation unit, an inter-pair difference calculation unit and an evaluation unit. The pixel extraction unit extracts, from an input image, a pixel region including a pair of block-boundary pixels in a boundary position of coding blocks and a pair of non-block-boundary pixels in a position other than the boundary position. The intra-pair difference calculation unit calculates a difference between the extracted pair of block-boundary pixels as a first difference, and a difference between the extracted pair of non-block-boundary pixels as a second difference. The inter-pair difference calculation unit calculates a difference between the first difference and the second difference as an amount of block distortion of the extracted pixel region. The evaluation unit evaluates an amount of block distortion of the input image based on the calculated amount of block distortion of the extracted pixel region.

    摘要: Input gray-scale bit map information is inputted to an image forming position extracting unit for extracting image forming position information. An input computer-formed image is inputted to an image forming position extracting unit for generating an image forming position. At an image forming position overlapping unit, two image forming positions are overlapped with each other, and the composed image forming position is sent to a pixel value calculating unit and an image forming position determining unit. The image value calculating unit measures a width of the composed image forming position and converts the measured value into a pixel value. The image forming position determining unit calculates a barycenter of the composed image forming position. The pixel value and the barycenter are sent as image information. Encoding without distortion can be executed by enhancing the precision of the barycenter.

    摘要: A plurality of reference pixel extracting means check their corresponding reference pixel ranges and pixel values in predetermined auxiliary regions. Reference pixel range selecting means selects a reference pixel range based on the checked pixel values. When the number of types of pixel values for an input image is found to be locally low in the selected reference pixel range, the number of reference pixels is increased. On the other hand, when the number of types of the pixel values for the input image is found to be locally large, the number of reference pixels is decreased. As a result, states can be generated by a Markov model image encoding system capable of improving encoding efficiency without increasing the number of the states sharply. Owing to the above construction, even when the number of tones for the input image is high upon Markov model image encoding, the number of reference pixels can be increased without abruptly increasing the number of states later on to improve compression efficiency.

    摘要: An image coding apparatus includes a color component. converter 2 for converting an input image signal 1 into predetermined color spaces which have been subdivided into independent color components, a segmenting circuit 4 for subdividing the converted image signals into predetermined image regions for the respective color components, a color information selecting circuit 9 for judging a condition of the color component of the input image based upon the components of the input image for each image region, and also a coding device 5 for performing a coding process with respect to the respective color components. In the color information selecting circuit 9, a judgement is made whether or not there is color information by comparing the pixel component of the pixel within the input image block with a predetermined threshold value. When it is judged that the input image block corresponds to the monochromatic information, the color difference component is not transferred or not stored. Only when it is judged that the input image block corresponds to the color information, the color difference component is transferred, or stored.
