Patent ID: 7896506

Claim:
An image processing apparatus comprising: a first image pick-up unit; a projecting unit that projects imaging light; an optical unit that transmits part of light entering from a first image pick-up direction and guides the part of the light to the first image pick-up unit while reflecting part of the imaging light projected from the projecting unit and outputting the reflected light in the first image pick-up direction, and reflects part of light entering from a second image pick-up direction and guides the part of the light to the first image pick-up unit while transmitting part of the imaging light projected from the projecting unit and outputting the part of the imaging light in the second image pick-up direction; and an attenuating unit that is movably placed between a first position in which imaging light transmitted through the optical unit can be received and a second position in which imaging light reflected by the optical unit can be received, and attenuates the received imaging light.
