    摘要： The present invention aims to execute effective compression even in the case where inputted image information has the bit number smaller than that of a pixel value, such as a tag, and besides in the case where the entropy increases if a prediction error obtained by subtraction of a value of a neighboring pixel from that of an object pixel is used for calculation of the entropy.According to the present invention, in an image encoding apparatus, the inputted image information is made to be packed image data of a fixed length and provided to a couple of predicting elements and a couple of prediction error calculating elements. The packed image data and prediction errors outputted from the couple of prediction error calculating elements are provided to a prediction error selecting element and one of the data and prediction errors having a smallest entropy is selected. A selecting element outputs an identification number of one of the predicting elements which succeeds in prediction, and if the predicting elements fail in prediction, the selecting element outputs the data or prediction error selected by the prediction error selecting element. The output from the selecting element is encoded by an encoding element to Huffman code, for example

    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： An image processing system includes an identification unit, a region division unit and a pixel value change unit. The identification unit identifies a second pixel among an image including a first pixel and the second pixel. A pixel value of the first pixel is not to be changed. A pixel value of the second pixel is to be changed. The region division unit divides the image into regions. The pixel value change unit changes the value of the second pixel to a predetermined value through a filtering process when the second pixel identified by the identification unit is included within the regions obtained by the region division unit.
