PROBLEM TO BE SOLVED: To switch and operate color image-pickup and monochromatic image- pickup. SOLUTION: A color separation filter 2 is arranged on the light reception surface of an image-pickup element 1, and respective color reception pixels are made to correspond to specified color components. In this case, for the respective segments of the color separation filter 2, a combination (for instance, Ye, G and Cy are selected) for including the color component transmitted in common in all the segments is selected. Then, a single color filter 11 matched with the color component transmitted through the respective segments of the color separation filter 2 is detachably arranged on an optical path. The color image-pickup is performed when the single color filter 11 is not mounted, and the monochromatic image pickup is performed at its mounting.
