Patent ID: 8681242

Claim:
An image signal processing system, comprising: a video input means, a video signal processing means which performs signal processing on a signal output from the video input means and generates a video signal; an input-output characteristic control means which controls characteristic of the video signal that the video signal processing means generates; and a subject recognition means which performs image processing on the video signal that the video signal processing means generates, and recognizes and detects subject information, wherein the input-output characteristic control means uses the subject information recognized by the subject recognition means in controlling the input-output characteristic; a first area input-output characteristic control means which controls a change in an input-output characteristic for each arbitrary area of a plurality of arbitrary areas, interlocked with a value of an input luminance signal; a first area luminance signal correction means which varies an input-output characteristic of a luminance signal in accordance with an output of the first area input-output characteristic control means; a second area input-output characteristic control means which controls a change in an input-output characteristic for each arbitrary area, interlocked with an output of the first area luminance signal correction means; and a second area luminance signal correction means which varies an input characteristic of the luminance signal in accordance with an output of the second area input-output characteristic control means.
