Patent ID: 7688376

Claim:
An image-capturing apparatus comprising: an image-capturing optical unit which reflects or transmits a light beam from an object; an image-capturing controller for controlling the image-capturing optical unit to allow the image-capturing optical unit to operate in a periodical manner; an image-capturing driver for driving the image-capturing optical unit based on the control operation by the image-capturing controller; at least one image-capturing unit which receives the light beam from the object entering via the image-capturing optical unit operating periodically so as to capture an image of the object; and a display device for displaying the image of the object captured by said at least one image-capturing unit, wherein the display device comprises: at least one light-emitting unit for emitting a light beam corresponding to the image of the object captured by said at least one image-capturing unit; a display optical unit for reflecting or transmitting the light beam emitted from said at least one light-emitting unit; a display controller for controlling the display optical unit to allow the display optical unit to operate in a periodical manner; and a display driver for driving the display optical unit based on the control operation by the display controller, wherein the image-capturing optical unit comprises a first lenticular-lens assembly in which a plurality of semi-cylindrical lenses are arrayed, wherein the image-capturing controller controls the first lenticular-lens assembly in a periodical manner such that the semi-cylindrical lenses in the first lenticular-lens assembly are shifted periodically, wherein the display optical unit comprises a second lenticular-lens assembly having the same structure as the first lenticular-lens assembly, and wherein the display controller controls the second lenticular-lens assembly in a periodical manner such that the semi-cylindrical lenses in the second lenticular-lens assembly are shifted periodically in phase with the corresponding semi-cylindrical lenses in the first lenticular-lens assembly.
