Patent ID: 11818339

Abstract:
In a case where it is identified based on fisheye information that an input image is a fisheye image, a block position computing section computes the position of a processing target block relative to a fisheye center, and outputs, to a table selecting section, positional information representing the computed position. In a case where it is identified based on fisheye information that an input image is a fisheye image, the table selecting section selects, on the basis of positional information, an intra-prediction mode table according to the position of a processing target block from a plurality of intra-prediction mode tables, and outputs the selected intra-prediction mode table to a prediction image generating section. By using the intra-prediction mode table supplied from the table selecting section and the reference image data read out from a frame memory via a selecting section, the prediction image generating section performs direction prediction and generates prediction image data for prediction modes represented in the intra-prediction mode table. An encoding or decoding process on an image on which distortions are generated can be performed efficiently.
