Abstract: PROBLEM TO BE SOLVED: To provide a technique for processing a picture by adaptively selecting a linear interpolation and a nonlinear interpolation. SOLUTION: The picture contents of a part of the image are sorted and in response to it, selection is carried out between a linear interpolation and a nonlinear interpolation for interpolating a data point to the part of the picture. In a part where the contact of the picture does not have an identified edge and in a part including an edge identified by being connected with an identified edge direction or a path of equal luminance, linear interpolation is used.

Abstract: PROBLEM TO BE SOLVED: To provide a method and system for image processing in an image compression expansion system employing hierarchical coding. SOLUTION: This invention produces a plurality of predictors with respect to an object pixel by using a plurality of predictors and generates a plurality of predictors with respect to at least one pixel denoting a causal context. This invention de at least one measure of a correlation between a plurality of predictors with respect to at least one pixel and data denoting the causal context, and also gives a predictor to an object pixel calculated as a weighted sum according to the measure of at least one correlation and a weighting policy.

Abstract: A compound camera system for generating an enhanced virtual image having a large depth-of-field. The compound camera system comprises a plurality of component cameras for generating image data of an object and a data processor for generating the enhanced virtual image from the image data. The data processor generates the enhanced virtual image by generating a first component virtual image at a first depth plane, generating a second component virtual image at a second depth plane, and inserting first selected pixels from the first component virtual image into enhanced the virtual image and inserting second selected pixels from the second component virtual image into the enhanced virtual image.
