Abstract
PURPOSE:To improve S/N deciding the image pickup time ratio of a three primary colors and correcting the break of a color balance in that case by amplifying an output to respective colors. CONSTITUTION:An illuminating light is projected on a rotary filter 8 through a lens 10 from a light source lamp 9 and this illuminating light is made incident on the end face of a light guide 7 via the filter for R, G, B of the rotary filter 8. A video signal from a solid-state image pickup element 4 is controlled in gain for every color in variable gain amplifiers 30-32 through a preamplifier 6, an amplifier 17 and a multiplexer part 18 and inputted to frame memories 20-22. Times for picking up the images of the respective primary colors are respectively defined to be tR, tG, tB and AR, AG, AB is defined to be Ai=integral Slambda.Qlambdaid (in this case, Slambda is spectral sensitivity of image pickup element 4, Qlambdai is i chrominance light made incident on image pickup element 4), and then, the rotary filter 8 is controlled so as to satisfy the condition of 0.2tGAG<=tRAR<tGAG, 0.1tGAG<=tBAB<tGAG.
