Abstract

An image generation apparatus outputs image data to a display apparatus, performs inverse conversion on image data, and transmits the image data to the display apparatus through an external data transmission line. The display apparatus includes a display device that is capable of displaying a High Dynamic Range (HDR) image or a Standard Dynamic Range (SDR) image through the external data transmission line. The inverse conversion is performed with respect to light emission characteristics of the display device. The image data is generated by the light emission characteristic inverse conversion unit. The transmission is performed in a case where light emission characteristics of the display device approximate an Electro-Optical Transfer Function (EOTF) of the HDR, a bit precision of image data is no lower than a bit precision of the external data transmission line, and an image of the HDR is to be displayed on the display device.
