<P>PROBLEM TO BE SOLVED: To reduce the influence of peripheral light, to perform miniaturization and resolution increase compatibly, and to suppress blur of an object image. <P>SOLUTION: The imaging apparatus includes: a light irradiation part 2 for irradiating an object space with light; an imaging device 1 having many light-receiving parts for performing photoelectric conversion; and a difference generation means 3 for generating a difference between a first image and a second image picked up in the imaging device 1. The imaging device 1 includes a first light-receiving part group (light-receiving part 10A) having spectral sensitivity characteristics X1 matched with the spectral characteristics of the light emitted by the light irradiation part 2 and a second light-receiving part group (light-receiving part 10B) having spectral sensitivity characteristics X2 close to the spectral sensitivity characteristics X1. Since a general imaging device can be used for the imaging device 1, the influence of the peripheral light is reduced, and the downsizing and the resolution increase are performed compatibly. Also, since the first image and the second image are simultaneously picked up, the blur of the object image is suppressed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
