BACKGROUND

1. Technical Field

The present disclosure relates to a display system, a display method, and a display apparatus that convert and display luminance of a video.

2. Description of the Related Art

Conventionally, an image signal processing apparatus for improving a displayable luminance level is disclosed (for example, refer to Unexamined Japanese Patent Publication No. 2008-167418).

SUMMARY

The above-described conventional technology needs further improvement.

In one general aspect, the techniques disclosed here feature a display system including: a conversion apparatus; and a display apparatus, wherein the conversion apparatus includes: one or more memories, and circuitry which, in operation, performs: acquiring a first luminance signal indicating a first code value obtained by quantization of a luminance value of a video, the luminance of the video being included in a first luminance range; converting the first code value into a second luminance value compatible with a second luminance range, a maximum value of the second luminance range being determined based on a luminance range of the display apparatus, the maximum value of the second luminance range being smaller than a maximum value of the first luminance range, and the maximum value of the second luminance range being larger than 100 nit; determining a third luminance value associated with the second luminance value in advance, the third luminance value being compatible with a third luminance range with a maximum value of 100 nit; converting the second luminance value compatible with the second luminance range into the third luminance value compatible with the third luminance range; determining a second code value by quantization of the determined third luminance value; converting the third luminance value compatible with the third luminance range into a third luminance signal indicating the second code value; and outputting the third luminance signal to the display apparatus, and wherein the display apparatus includes one or more memories, and circuitry which, in operation, performs: acquiring the third luminance signal and setting information indicating a display setting recommended to the display apparatus in display of the video; performing setting of the display setting of the display apparatus by using the acquired setting information; converting the second code value indicated by the acquired third luminance signal into the second luminance value compatible with the second luminance range by using the display setting of the display apparatus; and displaying the video on the display apparatus based on the second luminance value obtained by the third luminance conversion.

It should be noted that these general or specific aspects may be implemented as a device, an integrated circuit, a computer program, a computer-readable recording medium such as a CD-ROM, or any selective combination of a device, an integrated circuit, a computer program, or a computer-readable recording medium.

The above-described aspect can achieve further improvement.

Additional benefits and advantages of the disclosed embodiments will become apparent from the specification and drawings. The benefits and/or advantages may be individually obtained by the various embodiments and features of the specification and drawings, which need not all be provided in order to obtain one or more of such benefits and/or advantages.
