Abstract:
A conversion method for converting luminance of a video, including a luminance value in a first luminance range, to be displayed on a display apparatus includes: acquiring a first luminance signal indicating a code value obtained by quantization of the luminance value of the video; and converting the code value indicated by the acquired first luminance signal into a second luminance value determined based on a luminance range of the display apparatus, the second luminance value being compatible with a second luminance range with a maximum value smaller than a maximum value of the first luminance range and larger than 100 nit. This provides the conversion method capable of achieving further improvement.

Claim (Index 6):
A display method comprising:\n performing electro-optical transfer function (EOTF) conversion for high dynamic range (HDR) on a video signal having a luminance range of HDR to generate a first video linear signal; converting a first graphics signal having a luminance range with a maximum luminance 100 nit into a second graphics signal having a luminance range with a maximum luminance value that is decided in accordance with a maximum luminance that is displayable by the display; performing the EOTF conversion for HDR on the second graphics signal to generate a graphics linear signal; converting the first video linear signal into a second video linear signal with a luminance range having a maximum value, the maximum value being larger than 100 nit and being the maximum luminance that is displayable by the display; combining the second video linear signal with the graphics linear signal to generate a composite signal; and displaying the composite signal.
