A display method of displaying, on a display device , video of video data where luminance of video is defined by a first EOTF (Electro-Optical Transfer Function) indicating a correlation of HDR (High Dynamic Range) luminance and code values, wherein the video data includes peak luminance information indicating peak luminance of the video, the method comprising: acquiring the video data; performing first conversion where the luminance of the video is converted; and displaying the video on the display device using the result of the first conversion; characterized in that when performing first conversion, the luminance of the video is converted to a luminance corresponding to a dynamic range of a third EOTF, wherein the third EOTF is an EOTF where the dynamic range of luminance of a second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, the second EOTF is a 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 the maximum luminance, and the dynamic range of luminance of the second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF, by multiplying a value, obtained by dividing the displayable luminance by the peak luminance, by a variable representing luminance in the second EOTF. acquiring the video data; performing first conversion where the luminance of the video is converted; and displaying the video on the display device using the result of the first conversion; characterized in that when performing first conversion, the luminance of the video is converted to a luminance corresponding to a dynamic range of a third EOTF, wherein the third EOTF is an EOTF where the dynamic range of luminance of a second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, the second EOTF is a 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 the maximum luminance, and the dynamic range of luminance of the second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF, by multiplying a value, obtained by dividing the displayable luminance by the peak luminance, by a variable representing luminance in the second EOTF. the third EOTF is an EOTF where the dynamic range of luminance of a second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, the second EOTF is a 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 the maximum luminance, and the dynamic range of luminance of the second EOTF is reduced with the maximum luminance of the second EOTF matching the displayable luminance of the display device, while maintaining the relative relationship of luminance of the second EOTF, by multiplying a value, obtained by dividing the displayable luminance by the peak luminance, by a variable representing luminance in the second EOTF. <EOS>
