Title: SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND CAMERA SYSTEM
Abstract:
With this signal processing device, a prescribed signal level region of an HDR video signal can be easily verified on an SDR screen displayed on an SDR-compatible display device. Processing including at least SDR tone compression processing is performed on the HDR video signal to obtain a standard dynamic range video signal. The prescribed signal level region is detected from the HDR video signal. A display SDR video signal is obtained in that, on the basis of a signal indicating a prescribed signal level region, a display signal for displaying the prescribed signal level region is combined with the SDR image signal.
