PROBLEM TO BE SOLVED: To provide a technology for performing brightness range expansion processing suitable for a scene change when a scene change occurs. SOLUTION: When an expansion coefficient output mode determination part 250 detects a scene change, it changes an expansion coefficient output mode 250 from a normal mode to a scene change mode. An expansion coefficient derivation part 200 outputs an ideal expansion coefficient Gid(n) when the mode is changed to the scene change mode. The expansion coefficient derivation part 200 outputs a corrected expansion coefficient G(n) when the normal mode is maintained. COPYRIGHT: (C)2010,JPO&INPIT
