Claim Text:
1. A three-chip camera apparatus comprising: a color separation prism that includes an incident surface perpendicular to an optical axis, a first emission surface parallel to the incident surface, a second emission surface positioned between the incident surface and the first emission surface along a direction of the optical axis and inclined at a first inclination angle with respect to the optical axis, and a third emission surface positioned on a side opposite to the second emission surface with the optical axis interposed between the second and third emission surfaces and inclined at a second inclination angle greater than the first inclination angle with respect to the optical axis; a first imaging device that has a first surface extending in parallel to the first emission surface, a center of a first imaging region of the first imaging device being offset from a center of the first surface so that the center of the first imaging region is positioned between the center of the first surface and a first part of an outer shape of the first surface, the first part being closer to the third emission surface than to the second emission surface; a second imaging device that has a second surface extending in parallel to the second emission surface, a center of a second imaging region of the second imaging device being offset from a center of the second surface so that the center of the second imaging region is positioned between the center of the second surface and a second part of an outer shape of the second surface, the second part being closer to the first emission surface than to the incident surface; and a third imaging device that has a third surface extending in parallel to the third emission surface, a center of a third imaging region of the third imaging device being offset from a center of the third surface so that the center of the third imaging region is positioned between the center of the third surface and a third part of an outer shape of the third surface, the third part being closer to the incident surface than to the first emission surface.
