[Object] To contribute to the achievement of a workflow in which an HDR video and an SDR video are compatible with each other. [Solving Means] This video signal processing apparatus includes an HDR video generation unit including a first converter unit that performs OOTF conversion on an HDR video by using an exponentiation function for calculating an exponentiation of 1.2, where 100% is 1, to an input signal level of the HDR video having a range from a point of 0%, where an expression range of an input signal level of an SDR video is 100%, to a change point optionally determined within a range of 100% to 500%, and by using a linear function for multiplying an input signal level of the HDR video having a range higher than the change point by a predetermined coefficient to maintain a change rate of a calculation result in a portion of the change point calculated by using the exponentiation function.

A video signal conversion device includes a front end interface, a rear end interface, a video detector and a video processor. The front end interface is coupled to a video source to receive an input signal. The rear end interface is coupled to a video receiver. The video detector determines whether the input signal corresponds to HDR imaging format. The video detector generates a conversion command in response to the input signal corresponding to HDR imaging format. The video processor is coupled to the front end interface, the rear end interface and the video detector. When the video processor receives the conversion command, the video processor converts the input signal into an output signal with SDR imaging format. The video processor sends the output signal to the video receiver via the rear end interface.
