Abstract:
1. An image pickup apparatus comprising: a first image pickup portion that receives a first wavelength component of the object light, said first image pickup portion including a plurality of photoelectric conversion portions; a second image pickup portion that receives a second wavelength component of the object light, different from the first wavelength component, said second image pickup portion including a plurality of photoelectric conversion portions; a first optical system that guides object light to said first image pickup portion; and a second optical system that guides object light to said second image pickup portion, wherein, each of said first and second optical systems performs a filtering function whose transmission factor becomes smaller as a distance from an optical axis thereof becomes greater, and wherein, when a virtual object distance D (m) is defined as a function of an image pickup angle θ(°) of said first and second optical systems to be D=1.4/tan (θ/2), an interval between the optical axes of said first and second optical systems is set change in an interval between an object image received by one of said first and second image pickup portions and an object image received by the other one of said first and second image pickup portions between when an object is at the virtual distance and when the object is at infinity is smaller than a pixel pitch of said image pickup portions multiplied by two.
