Abstract
There are provided an apparatus and method capable of displaying HDR image on SDR display apparatus without large deterioration in image quality. The apparatus has a display control unit for converting an HDR image signal and generating an output signal into a display unit. The display control unit converts an input HDR image signal in case the HDR image signal is input, and generates and outputs a converted HDR signal according to a γ correction curve with an I/O characteristic reverse to a γ curve corresponding to an I/O characteristic of an SDR display unit to the display unit. In case the γ curve corresponding to the I/O characteristic of the SDR display unit is a 2.2-th power curve, the display control unit converts the input HDR image signal, and generates and outputs a converted HDR signal with I/O characteristic according to a (1/2.2)-th power curve to the display unit.
