Abstract
A luminance space conversion section of an information processing apparatus converts an image signal represented in a luminance space corresponding to an SDR into a signal represented in a luminance space corresponding to an HDR, and outputs the converted signal to a synthesis processing section that performs alpha blend processing on an HDR image. In an adjustment mode, a parameter adjustment section allows a display apparatus to display an adjustment image represented in the SDR and adjusts a parameter used for a conversion of the luminance space so that a change in a display image is made small before and after converting the luminance space. The parameter is stored in a conversion parameter storage section after the adjustment and is used when a luminance signal conversion section performs conversion processing.
