Abstract
A camera provided with a housing having a plurality of entrance windows through each of which extraneous light rays are taken in, an image pickup device mounted in this housing, an optical element that is disposed in the housing and is operative to form images obtained from extraneous light rays taken in through the plurality of entrance windows on the imaging plane of the image pickup device, a light Shielding member that is provided in such a way as to be upright on the imaging plane of the image pickup device and to divide the imaging plane of the image pickup device into imaging fields on which images are respectively formed from the extraneous light rays taken in through the plurality of entrance windows, an aperture limitation remember that is placed in a stage preceding the light shielding member and has an aperture to limit the size of an incidence optical path of each of extraneous light rays from which images are formed on the imaging plane of the image pickup device, a diaphragm member that is disposed in the stage preceding the light shielding member in such a manner as to be able to move in a direction perpendicular to an optical axis and is operative to regulate the quantities of incident light of the imaging fields by overlapping with the aperture in the direction of the optical axis, and a drive unit for moving this diaphragm member in a direction perpendicular to the optical axis.
