Display system, display method, and display apparatus

A display apparatus comprising:

• an electro-optical transfer function (EOTF) converter that receives a video signal 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 converting the video signal into a pseudo High Dynamic Range 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 pseudo High Dynamic Range signal having the second luminance range based on the second luminance value,
• wherein the maximum value of the second luminance range is a maximum possible display peak luminance (DPL) that the display is capable of displaying, and is greater than the maximum luminance value of the SDR signal,
• wherein the luminance converter performs conversion of the first luminance value into the second luminance value, based on characteristic information on a characteristic of the display apparatus,
• 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,
• the characteristic information indicates one of the display peak luminance (DPL) displayable by the display, a display mode of the display, and an input-output characteristic supported by the display, and
• wherein the content luminance information is acquired as metadata of the video signal.
