Claim Text:
1. An electronic apparatus comprising: a spectral filter which selectively outputs light with a predetermined wavelength from input light, and is capable of changing the wavelength of the output light; a filter driving unit which causes the spectral filter to sequentially output light with a predetermined red wavelength which is included in a red wavelength range, light with a predetermined green wavelength which is included in a green wavelength range, and light with a predetermined blue wavelength which is included in a blue wavelength range by controlling the spectral filter; an imaging element which receives the light output from the spectral filter, and obtains a red image corresponding to the light with the red wavelength, a green image corresponding to the light with the green wavelength, and a blue image corresponding to the light with the blue wavelength; and a composition unit which generates a composite image in which the red image, the green image, and the blue image are composited, wherein the filter driving unit causes the spectral filter to change the red wavelength in the red wavelength range every time when the red image is obtained by the imaging element, causes the spectral filter to change the green wavelength in the green wavelength range every time when the green image is obtained by the imaging element, and causes the spectral filter to change the blue wavelength in the blue wavelength range every time when the blue image is obtained by the imaging element.
