To appropriately perform AF control or framing during photographing in a dark place.

When a photographing mode is a spectral photographing mode as the result of decision in a step S3, in response to a user operation at an operation input section 22, the wavelength band and the photographing wavelength band of a through video image are selected, respectively (step S4). Continuously, an electronic control filter is set to the wavelength band for the through video image selected in the step S4, and this through video image of the selected band is displayed on a display section 85 (step S5). Furthermore, zoom processing, AF processing and the like are carried out (step S6). In the process of the step S6, since the wavelength band of a spectral filter 59 in the step S5 is set to the wavelength band selected in the step S4, the AF processing or AE processing is also performed on the basis of an image, in the wavelength band, transmitted through the spectral filter 59.
