Solid-state color television camera
First Claim
1. A solid-state color television camera comprising:
- an image pickup device;
a color filter array placed in front of said solid-state image pickup device;
a color separation circuit for extracting three primary colors, red, green and blue, from a multiplex signal derived from said image pickup device;
said filter array including a plurality of color filter rows arranged extending in the horizontal scanning direction, each of said color filter rows having color filter blocks with different color transmission characteristics alternately arranged, in which a first color filter row selected from said plurality of color filter rows is made up of first and second color filter blocks with first and second color transmission characteristics, said first color filter row is disposed adjacent to a second color filter row made up of and alternately arranged third and fourth filter blocks respectively having a third color transmission characteristic and a given transmission characteristic, and said first and second color filter blocks of said first color filter row are disposed and shifted a given length in the horizontal scanning direction, with respect to said third and fourth color filter blocks of said second color filter row; and
said solid-state image pickup device having a plurality of photosensors disposed corresponding to said color filter blocks of said color filter array.

Abstract
An incident light image is projected onto a CCD device through a color filter array. The color filter array is provided with a color filter row (n'"'"') with the same construction as that of a color filter row (n) corresponding to an nth horizontal scanning for interlacing purposes, which is disposed between the color filter row (n) and a (n+1)th color filter row corresponding to a (n+1)th horizontal scanning. The color filter blocks forming the color filter rows (n) and (n+1) are disposed and shifted by the half of a length (L) of each block extending in the horizontal scanning direction. All of the color filter rows forming the color filter array each have an arrangement of color filter blocks with two different color transmission characteristics alternately arranged.
