Abstract:
To enable to easily check a predetermined signal level region of an HDR video signal on an SDR screen displayed on an SDR-compliant display device.Processing at least including gradation compression processing for SDR is performed on the HDR video signal to obtain a standard dynamic range video signal. A predetermined signal level region is detected from the HDR video signal. An SDR video signal for display is obtained by combining a display signal for displaying the predetermined signal level region with an SDR video signal on the basis of a signal indicating the predetermined signal level region.
