Abstract

PURPOSE:To enable to reject the noise of a fixed pattern without deteriorating the resolution, by separating each video element of two two-dimensional solidstate image sensors into three types of spectral sensitivity requiring visual high resolution and not requiring it visually. CONSTITUTION:Corresponding to photodetectors 42, 48 of color solidstate image sensing devices 41, 47, mosaic shape color filter arrays 43, 49 are located, and green color transmission filters 44 having the 1st photo sensing is located to each of the arrays 43, 49. Further, to the arrays 43, 49, the 2nd and 3rd photo sensing red color transmission filters 45 and blue color transmission filters 46 are located, and scanning is made toward the arrow with the scanning lines of an odd and even number of the respective devices 41, 47. Further, at a video element with respect to the one of vertical registers in the video elements of the devices 41, 47, the video elements sensing the red and blue color light and also green color light are included to make the video elements sensing the blue and red colors are made to the same number, allowing to eliminate the fixed pattern noise due to smear phenomenon.
