Three-dimensional image capturing device
First Claim
1. A three-dimensional image capturing device, comprising:
- a center light emitting element that irradiates a distance measuring light beam to a predetermined area of a measurement subject, which reflects said distance light beam to generate a first reflected light beam;
a plurality of peripheral light emitting elements that are disposed around said center light emitting element, and irradiate distance measuring light beams to peripheral areas around said predetermined area, which reflect said distance light beams to generate second reflected light beams;
a distance measurement information sensing processor that receives said first reflected light beam and said second reflected light beams on a light receiving surface of an imaging device, so that distances from said imaging device to said predetermined area and said peripheral areas are sensed in accordance with the amount of light received by said distance measurement information sensing processor; and
a light emission timing adjusting processor that adjusts the irradiation timings of said center light emitting element and said peripheral light emitting elements, in such a manner that, when said measurement subject is a flat plane parallel to said light receiving surface, said first reflected light beam and said second reflected light beams are simultaneously received by said light receiving surface.

Abstract
A three-dimensional image capturing device has a center LED and peripheral LEDs which are arranged around the center LED. The center LED and peripheral LEDs irradiate distance measuring light beams to a measurement subject. The distance measurement light beams are reflected by a surface of the measurement subject, and the reflected light beams are received by an imaging device, so that distances from the imaging device to the measurement subject are sensed in accordance with the received light amount. The irradiation timings of the center LED and the peripheral LEDs are adjusted, in such a manner that, when the measurement subject is a flat plane parallel to the light receiving surface of the imaging device, the reflected light beams from all of the LEDs are simultaneously received by the imaging device.
