Abstract:
A color solid-state imaging apparatus, comprising a plurality of pixels conducting photoelectric conversion arranged in a matrix and color filters disposed so as to correspond to the plurality of pixels,wherein the color filters include first filters of a first kind, second filters of a second kind, and third filters of a third kind, each kind of filter having spectral characteristics different from the others, the plurality of pixels are arranged at a pitch L in a vertical direction to form columns, and each of the columns is arranged at a pitch of L/2 in a horizontal direction orthogonal to the vertical direction, the pixels disposed in even-number columns are shifted in the vertical direction by L/2 from the corresponding pixels disposed in odd-number columns, the first filters are disposed so as to correspond to all the pixels arranged in the odd-number columns, the second filters are disposed so as to correspond to half of the pixels arranged in the even-number columns at a predetermined period, the third filters are disposed so as to correspond to the remaining pixels in the even-number columns, horizontally adjacent pixels from each even-number column define horizontal rows and horizontally adjacent pixels from each odd-number column define subsequent horizontal rows, a video signal on each pixel is read for scanning the plurality of pixels in the horizontal direction in a zigzag manner from one horizontal row and a subsequent horizontal row, and each pixel is arranged in a shape of a regular square when viewing the arrangement of filters in a diagonal line.
