<p>PROBLEM TO BE SOLVED: To obtain a digital video signal in which undesired change in luminance or chromaticity on a screen attributable to change in a signal level is properly corrected. SOLUTION: The device is provided with a non-linear processing part 47R (47G, 47B) for correcting through non-linear processing a signal level on a digital video signal, in accordance with the display characteristic of a liquid crystal display panel 52R (52G, 52B) on which a picture is displayed based on the digital video signal; provided with a three-dimensional correcting part 48R (48G, 48B) for correcting three-dimensionally the signal level on each pixel segment forming the digital video signal, in accordance with the horizontal and vertical position of the pixel, in the display screen of the picture display part corresponding to the pixel segment, and with the signal level of the pixel segment; and provided with a synthesizing part 49R (49G, 49B) for synthesizing the corrected digital video signal from the non-linear processing part with the three- dimensionally corrected digital video signal consisting of the pixel segments to which three-dimensional correction is imparted from the three-dimensional correcting part.</p> |
