Signal processing device, signal processing method, camera system, video system, and server
To enable HDR video signals of a plurality of signal interfaces to be satisfactorily handled. A processing unit processes a linear high dynamic range video signal and obtains a high dynamic range video signal that has undergone a grayscale compression process. The processing unit is able to perform grayscale compression processes of a plurality of signal interfaces. For example, when a grayscale compression process of another signal interface other than a reference signal interface is performed, the processing unit further performs a process of adding characteristics of system gamma of the reference signal interface and a process of cancelling out characteristics of system gamma of the other signal interface.
