Patent ID: 7868936

Claim:
A multispectral image capturing apparatus, comprising: a color image capturing unit configured to capture a color image of a subject; a filter arranged opposite to the color image capturing unit, configured to make light of standard RGB from the subject incident on the color image capturing unit at a predetermined timing, so that the color image capturing unit captures an image of main three bands having spectral sensitivity characteristics of the standard RGB, of spectral sensitivity characteristics of six bands, and configured to make light of auxiliary three bands incident on the color image capturing unit at a timing different from the predetermined timing, the auxiliary three bands corresponding to remaining bands other than the main three bands of the spectral sensitivity characteristics of the six bands, and each of the auxiliary three bands having spectral sensitivity characteristics in a bandwidth narrower than a bandwidth for the RGB, so that the color image capturing unit captures an image of the remaining bands other than the main three bands of the spectral sensitivity characteristics of the six bands; a synthesizing unit configured to synthesize the image of the main three bands and the image of the auxiliary three bands as captured at the different timings by the color image capturing unit, to generate an image of the six bands; and an output unit configured to output the image of the main three bands captured by the color image capturing unit.
