Abstract:
A display device is a display device having a display that displays an image based on a received image signal. This display device includes: a memory that stores maximum luminance information regarding maximum luminance that the display can display; a determiner that determines whether the image signal is an HDR image signal specified by relative luminance; a first converter that, when the determiner determines that the image signal is the HDR image signal specified by the relative luminance, subjects luminance information obtained from the image signal to nonlinear conversion based on a luminance characteristic of the display; and a second converter that converts the luminance information that has been subjected to the nonlinear conversion by the first converter such that the display displays an image at increased luminance within a luminance range determined in accordance with the maximum luminance information.
