摘要： To provide a technology for performing brightness range expansion processing suitable for a scene change when a scene change occurs. If an expansion coefficient output mode determination module 250 detects a scene change, it changes an expansion coefficient output mode from a normal mode to a scene change mode. An expansion coefficient derivation module 200 outputs an ideal expansion coefficient Gid(n) if the scene change is detected, and outputs a corrected expansion coefficient G(n) if the scene change is not detected.

摘要： Technology for carrying out a luminance range expansion process is provided. In the technology, the luminance range expansion process is carried out in a manner appropriate to the luminance histogram of image data. Using the white peak value WP which represents the maximum value of luminance and the APL which represents the mean value thereof in the luminance histogram of image data, an expansion coefficient for use in the luminance range expansion process is derived by referring to an expansion coefficient lookup table 210. On the basis of the expansion coefficient, the luminance range expansion process is performed on the image data.
