Summary:PROBLEM TO BE SOLVED: To obtain an image pickup device with which images within a desired wavelength range can be picked up. SOLUTION: This device is provided with plural electrochromic(EC) elements 3-1 to 3-3 for which the ranges of the wavelengths of light to be transmitted in a light transmitting state are mutually different. At least two of these plural EC elements are simultaneously controlled into the light transmitting state by a controller 4. The light after the all of at least two EC elements controlled into the light transmitting state are transmitted through, is received by a detecting element 1. Thus, the image having transmission characteristics combining the transmission characteristics owing to two EC elements can be picked up.
