Abstract
Abstract A CCD (charge-coupled device) color camera is disclosed, wherein an installed CCD imager is capable of reading out signals of two adjacent rows of sensing elements simultaneously, besides employing an interlacing scanning technique. A color coding filter facing a sensing area of the CCD imager is arranged basically to have successive sets of color elements each set consisting of a blue color element and three red color elements in the vertical direction. In the signal processing system, two adjacent lines of video signals derived from the CCD imager are employed in order to separate red and blue color signals.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
A solid state color camera employing at least one solid state image sensing device which simultaneously reads out signals of adjacent two rows of sensing elements as a video signal of a single horizontal scan line in sequence with an interlacing technique, comprising: (A) color coding filter means having a plurality of color elements corresponding to respective sensing elements of said solid state image sensing device, said filter means being arranged to have successive sets of color elements each consisting of a first color element and three second color elements in the vertical direction, and (B) color signal processing means for separating first and second color signals corresponding to said first and second color elements by arranging two adjacent lines of video signals derived from said solid state imaging device.
Claim 2
Dependent Claim
130 words
A solid state color camera employing at least one solid state image sensing device which simultaneously reads out signals of adjacent two rows of sensing elements as a video signal of a single horizontal scan line in sequence with an interlacing technique, comprising: (A) color coding filter means having a plurality of color elements corresponding to respective sensing elements of said solid state image sensing device, said filter means being arranged to have successive sets of color elements each consisting of a first color element and three second color elements in the vertical direction, and (B) color signal processing means for separating first and second color signals corresponding to said first and second color elements by arranging two adjacent lines of video signals derived from said solid state imaging device.
Claim 3
Dependent Claim
40 words
A solid state color camera as set forth in claim 1, wherein said first color elements of one column of said color coding filter means are positioned in an interleaving relation with the first color elements of the alternate columns.
Claim 4
Dependent Claim
33 words
A solid state color camera as set forth in claim 2, wherein columns of third color elements only are arranged in an alternate relation with columns of said first and second color elements.
Claim 5
Dependent Claim
17 words
A solid state color camera as set forth in claim 3, wherein said third color is green.
Claim 6
Dependent Claim
42 words
A solid state color camera as set forth in claim 1, wherein a second solid state imaging device is employed, and second color coding filter means for third color elements only is disposed in front of said second solid state imaging device.
Claim 7
Dependent Claim
17 words
A solid state color camera as set forth in claim 5, wherein said third color is green.
Claim 8
Dependent Claim
56 words
A solid state color camera as set forth in claim 1, wherein columns having successive sets of color elements each consisting of a first color element and three third color elements in the vertical direction are arranged in an alternate relation with the columns having said successive sets of a first and three second color elements.
Claim 9
Dependent Claim
17 words
A solid state color camera as set forth in claim 7, wherein said third color is green.
Claim 10
Dependent Claim
23 words
A solid state color camera as set forth in claim 1, wherein said first color is blue and said second color is red.
