Image encoding apparatus, image decoding apparatus, image encoding method, image decoding method, and program

摘要

An image encoding apparatus (100) comprises: an image conversion unit (101) that converts an input image signal (20) having a first resolution to a second image signal having a second resolution lower than the first resolution; a region acquisition unit (112) that acquires a region of interest (40) in an image represented by the input image signal (20); a region information output unit (113) that outputs first region information indicating the region of interest (40); a first encoding unit (12) that acquires, from the input image signal (20), a partial region signal corresponding to the region of interest (40) and that encodes the partial region signal into a first encoded signal; a second encoding unit (11) that encodes the second image signal into a second encoded signal; and an output unit (119) that outputs the second encoded signal and the first encoded signal.
