An
image signal processing apparatus includes an image
pickup unit operable to take image information; an
image signal-
processing unit operable to process the image information; a display unit operable to display the image information on a display; a recording unit operable to
record the image information onto a recording medium; a reproducing unit operable to reproduce the recorded image information; a
communication unit operable to communicate with an
external image display to display the image information on the
external image display; an obtaining unit operable to obtain an adjustive
image pattern used to adjust
image quality so as to correspond to image-displaying performance of the
external image display; an adjustive
image display unit which permits the adjustment of the
image quality by correcting parameters used by the
image signal-
processing unit to perform image
signal processing based on the adjustive
image pattern, the adjustive
image display unit acting to display the adjustive
image pattern representing an uncorrected state and a corrected state on the external
image display; and a correcting unit operable to correct the
image quality to match displaying characteristics of the external image display by correcting the parameters used by the image
signal-processing unit to perform the image
signal processing so as to correspond to the corrected adjustive image pattern displayed by the adjustive image display unit.
