Assignee: SONY GROUP CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A video signal processing system, comprising:
a video signal generation apparatus that generates an HDR video and an SDR video;
an HDR monitor that performs signal processing to display the HDR video generated by the video signal generation apparatus on a first monitor; and
an SDR monitor that performs signal processing to display the SDR video generated by the video signal generation apparatus on a second monitor,
the video signal generation apparatus including
HDR video generation circuitry including
first circuitry configured to perform an OOTF conversion, by using a predetermined function, on an input video signal having a range from a predeteimined reference point to a change point determined, the OOTF conversion being analogous to OOTF conversion for the SDR video, and

SDR video generation circuitry including
second circuitry configured to perform an OETF conversion on the input video signal to generate the SDR video,

the SDR monitor including
SDR video signal processing circuitry configured to perform gamma processing using an EOTF on the SDR video generated by the video signal generation apparatus.
