Image processing apparatus and method capable of suppressing image quality deterioration, and storage medium

An image processing apparatus capable of suppressing image quality deterioration in an output image region determined based on reference pixel regions including image ends. The image processing apparatus includes a coefficient selection value generator that generates a coefficient selection value according to a filter coefficient changeover control signal supplied from a region information controller. In accordance with the coefficient selection value, filter coefficient sets are respectively output from coefficient tables. One of the filter coefficient sets is selected by a selector in accordance with a coefficient set selection value supplied from a coefficient set selection unit. Using filter coefficients that constitute the selected filter coefficient set, an image processor performs arithmetic processing on image data on a per pixel of interest basis while referring to peripheral pixels.

Method and apparatus for transforming moving picture coding system

A first data sequence generated by a first moving picture coding system having an intra-frame coding mode and an inter-frame coding mode is transformed to a second data sequence generated by a second moving picture coding system having an intra-frame coding mode and an inter-frame coding mode. The method includes prereading a coding mode of a successive frame succeeding a present frame from the first data sequence, judging whether or not a preread coding mode of the successive frame is the intra-frame coding mode and determining whether or not to code the present frame by the second moving picture coding system corresponding to a generated code amount of the second data sequence when the coding mode of the successive frame is the intra-frame coding mode. Data coded by the intra-frame coding mode existing in the first data sequence is transformed to the second data sequence.
