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