<p>PROBLEM TO BE SOLVED: To provide a color image pickup device that can simultaneously obtain a pseudo color image, a visible light color image and a near-infrared image.SOLUTION: A color image pickup device has an image sensor (105) having four kinds of color filters arranged, an optical band separation filter (103) which is arranged in an incident light passage of the image sensor, intercepts a predetermined wavelength band with a photodetecting characteristic of an optical sensor unit and allows passage of a visible light band and a long wavelength side near-infrared-ray band, a color separation processor (702) for separating four kinds of data from pixel outputs of the color filters, and a data calculation processor (703) for generating plural kinds of red, green and blue data from the four kinds of color data and adjusting the size of individual data of each red, blue and green data to recombine the red, blue and green data, thereby obtaining red, green and blue components.</p> |
