Patent ID: 7492403

Claim:
A solid-state image sensing device comprising: color photodiodes and luminance photodiodes disposed in a two-dimensional matrix, each photodiode sensing light, converting sensed light into an electric signal; a vertical charge coupled device (CCD) which receives the electric signals from each of a plurality of rows corresponding to photodiodes having a particular color or luminance, and generates a first added video signal result by adding in the vertical CCD a first electric signal from a first photodiode having the particular color or luminance with a second electric signal from a second photodiode having the same color or luminance as the first photodiode, wherein the second photodiode is located a proportional number of rows distant from the first photodiode, wherein the proportional number is an integer multiple of the number of the plurality of rows and equal to a reciprocal of a vertical sub-sampling ratio, wherein the integer of the integer multiple is greater than one, and wherein the vertical CCD vertically transmits the first added video signal result; and a horizontal CCD which receives a plurality of first added video signal results from the vertical CCD, and generates a second added video signal result by adding sequentially in the horizontal CCD the same number of the first added video signal results for the same color or luminance as the number of the plurality of rows, wherein the horizontal CCD horizontally transmits and outputs the second added video signal results, and wherein the number of the plurality of rows is the same for the color photodiodes and for the luminance photodiodes, respectively.
