ABSTRACT:
A calorimetric apparatus includes an image pickup unit, an optical unit, a plurality of optical bandpass filters, a switching unit, an arithmetic processing unit, and an optimum filter selection unit. The image pickup unit picks up the image of light from a target object. The optical unit allows the light from the target object to form an image on the image pickup unit. The plurality of optical bandpass filters are arranged between the target object and the image pickup unit and have pass bands different from each other. The switching unit switches the plurality of optical bandpass filters. The arithmetic processing unit performs arithmetic processing for colorimetry on the basis of the spectrum data of the target object whose image is picked up. The optimum filter selection unit selects, from the plurality of optical bandpass filters, a filter suitable for colorimetry by the arithmetic processing unit.
