Abstract: An imaging section that detects the amount of light separated by a wavelength tunable interference filter to acquire a spectroscopic image (imaging device and light amount acquisition section) detects the amount of light successively separated for three wavelengths to acquire spectroscopic images for producing a combined image. A display controller causes a display section to display a combined image based on the spectroscopic images for producing the combined image. A specified position detection section identifies based on user's operation a specified position where a colorimetry result is to be outputted. The imaging section detects the amount of light successively separated for a plurality of wavelengths by the wavelength tunable interference filter to acquire spectroscopic images for colorimetry corresponding to the plurality of wavelengths. A colorimetry section measures the color in the specified position by using the amount of light obtained from each of the spectroscopic images for colorimetry.

Abstract: An imaging device outputs imaging data captured with a predetermined exposure time, and a brightness determination unit determines whether the brightness of the imaging data is within a predetermined range. Re-imaging is performed with the exposure time changed when the brightness of the imaging data is not within the predetermined range. The re-imaging is performed with the exposure time lengthened when the brightness of the imaging data is less than a determination value, and the re-imaging is performed with the exposure time shortened when the brightness of the imaging data is saturated.
