Abstract:
A video signal conversion device is realized in which even in a case where an HDR video signal following a first video format is converted into a HDR video signal following a second video format, supplementary information related to the HDR video signal following the original first video format is not lost. The video signal conversion device (1 or 40) includes: a conversion unit (5) that converts the high dynamic range video signal following the first video format into the high dynamic range video signal following the second video format; and an output unit (12) that outputs the supplementary information which is related to the high dynamic range video signal following the first video format.
