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 indicating a correlation of HDR luminance and code values. The method includes: acquiring the video data; performing, regarding each of multiple pixels making up the video in the acquired video data, first determining of determining whether luminance of that pixel exceeds a first predetermined luminance; performing, regarding each of the multiple pixels, dual tone mapping where luminance of that pixel is reduced by a different format in a case of the luminance of the pixel being found to exceed the first predetermined luminance from the first determining, and a case of the luminance of the pixel being found to be equal to or lower than the first predetermined luminance; and displaying the video on the display device using the results of the dual tone mapping.
