Abstract

Provided is a display method of displaying, on a display device, video of video data where luminance of video is defined by a first EOTF corresponding to HDR. The method includes: acquiring the video data; performing first conversion where the luminance of the video is converted to a luminance corresponding to a dynamic range of a third EOTF, where, with regard to a second EOTF that is part of the first EOTF and is the part of a luminance range where the peak luminance indicated by the peak luminance information included in the acquired video data is maximum luminance, the dynamic range of luminance of the second EOTF is reduced with maximum luminance of the second EOTF matching displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF; and displaying the video on the display device using the result of the first conversion.
