Abstract:
A three-dimensional image capturing device, comprising:a light source that has a plurality of irradiating units to irradiate a distance measuring light beam to a subject, the intensities of said distance measuring light beams being different from each other; a modulating processor that selects a combination of said irradiating units to be turned on, the modulating processor varying the selected combination of irradiating units to be turned on so that the intensity of said distance measuring light beam is modulated in accordance with the time elapsed from when said light source started irradiating said distance measuring light beam; a light sensing processor that senses said distance measuring light beam reflected by said subject in accordance with a timing of the modulation, to obtain luminous information of said subject; and a distance obtaining processor that obtains distance information of said subject based on said luminous information.
