Claim 0:
1. A display apparatus comprising:
an electro-optical transfer function (EOTF) converter that receives a video signal, being received by using an input interface, having a first luminance range and performs EOTF conversion on the video signal to obtain a first luminance value;
a luminance converter, which is provided for producing a second video signal having a second luminance range, a maximum value of the second luminance range being smaller than a maximum value of the first luminance range, the luminance converter that converts the first luminance value into a second luminance value within the second luminance range, the maximum value of the second luminance range being larger than a maximum value of a luminance of a Standard Dynamic Range (SDR) signal, and the maximum luminance value of the SDR signal being 100 nit; and
a display that displays the second video signal having the second luminance range based on the second luminance value,
wherein the maximum value of the second luminance range is a predetermined luminance within a displayable range of the display,
wherein the luminance converter performs conversion of the first luminance value into the second luminance value based on content luminance information of the video signal, and
wherein the content luminance information includes an average value of luminance values of the video signal (CAL: Content Average Luminance) and a maximum value among luminance values of the video signal (CPL: Content Peak Luminance).
