Abstract:
1. An image pickup apparatus comprising: first and second image pickup portions for receiving at least a first wavelength component of object light and a second wavelength component of the object light different from the first wavelength component, respectively; and first and second optical systems for guiding the first and second wavelength components of the object light to be received by said first and second image pickup portions to said first and second image pickup portions, respectively, via different optical paths, said first and second optical systems being formed to have respective shapes so that the focal length of said first optical system with regard to the first wavelength component is equal to the focal length of said second optical system with regard to the second wavelength component, wherein, when a virtual object distance D (m) is defined as a function of an image pickup angle θ (°) of said first or second optical systems to be D=1.4/tan (θ/2), an interval between optical axes of said first and second optical systems is set such that a change in an interval between an object image of the first wavelength component received by said first image pickup portion and an object image of the second wavelength component received by said second image pickup portion between when an object exists at the virtual object distance and when the object exists at infinity is smaller than a pixel pitch of said image pickup portions multiplied by two.
