US Patent 11403741 Video signal processing apparatus, video signal processing method, and program

There is provided a video signal processing apparatus, including: a first interface configured to obtain a first video signal imaged within a first dynamic range; a second interface configured to obtain information for specifying a partial area of the obtained first video signal; and an arithmetic processing circuit configured to calculate a representative value of brightness of the first video signal of the partial area, to compress a dynamic range of the first video signal depending on the calculated representative value, and to generate a second video signal, a dynamic range of the second video signal being restricted to a second dynamic range narrower than the first dynamic range.
