Patent ID: 6882364

Claim:
A solid-state imaging apparatus for picking up light representative of a subject and incident via apertures and executing signal processing with resulting signals to thereby output signals lying in a broad frequency band, said apparatus comprising: an image pick-up section comprising: a photosensitive portion including photosensitive devices for photoelectrically transducing the light incident via said apertures, wherein nearby ones of said photosensitive devices are shifted from each other in a vertical direction and/or a horizontal direction in a bidimensional pattern; electrodes arranged outside of apertures formed in a front of said photosensitive portion for picking up signals output from said photosensitive devices; and vertical transfer registers for sequentially transferring the signals output from said electrodes in a vertical direction of said photosensitive portion; a plurality of color filters respectively arranged on the apertures of said photosensitive devices and each having a particular spectral characteristic; a gamma correction circuit for executing gamma correction with the signals output from said vertical transfer registers; a digitization circuit for digitizing outputs of said gamma correction to thereby output digital data; a recording/reproduction circuit for recording or reproducing the digital data output from said digitizing circuit; and a signal processing circuit for attaching, assuming that regions void of said photosensitive devices in plane data output from said recording/reproducing circuit and ascribable to a shift of said photosensitive devices are virtual photosensitive devices, importance to accurate color reproduction and to a horizontal and/or a vertical resolution and executing item-by-item signal processing on the basis of data output from said photosensitive devices adjoining said virtual photosensitive devices, said signal processing circuit comprising: a calculation circuit for attaching importance to the accurate color reproduction and to the horizontal and/or the vertical resolution and executing the item-by-item signal processing; a pseudo addition circuit for adding, in a pseudo frequency fashion, component signals output from said calculation circuit and attaching importance to the color reproducibility and the resolution, respectively; and an overlap prevention circuit for preventing, when signals output from said calculation circuit and respectively attaching importance to the horizontal resolution and the vertical resolution include identical frequency bands, said identical frequency bands from overlapping each other.
