Patent ID: 7463286

Claim:
An image data processing apparatus for performing a predetermined signal processing on input image data and generating output data for supplying to an external apparatus, the image data processing apparatus comprising: a first processing circuit for performing a first signal processing with respect to image data so as to produce a first set of image data; and a second processing circuit for performing with respect to the image data a second signal processing, which is independent from the first signal processing, so as to produce a second set of image data, wherein the first processing circuit comprises a first filter for attenuating a first bandwidth of the image data so as to generate a first luminance data, a gamma corrector for performing a gamma correction processing on the first luminance data, and a first contour emphasizer for performing a first contour emphasis processing with respect to the gamma-corrected data; the second processing circuit comprises a second filter for attenuating a second bandwidth of the image data so as to generate a second luminance data, and a second contour emphasizer for performing a second contour emphasis processing with respect to the second luminance data; and the first and second processing circuits execute the first and second signal processing in a parallel manner, and output the first and second sets of image data as output data.
