Section: claims

1. A laser emitting device applied in a three-dimensional image capturing device, comprising:a plurality of laser devices that radiate pulse modulated laser beams irradiating a measurement subject for a distance measurement, said plurality of laser devices being separated into predetermined groups having plural laser devices; anda laser emitting operating processor that controls said laser devices to radiate laser beams concurrently in each of said predetermined groups, wherein each laser device of said plurality of laser devices in each of said predetermined groups is disposed at predetermined intervals, each illuminating area of a laser beam radiated from said each laser device overlapping each other at a distance of said measurement subject, wherein each of said predetermined groups comprises a pair of laser devices that are disposed opposite each other with a center of a photographing lens in between. 2. The device of claim 1, wherein said each group of laser devices radiates laser beams at a different timing. 3. The device of claim 1, wherein said plurality of laser devices are disposed at regular intervals along a periphery of a photographing lens in a circular arrangement. 4. The device of claim 3, wherein at least one laser device of a predetermined group is disposed between said plural laser devices forming another predetermined group. 5. The device of claim 4, wherein a number of said plurality of laser devices is six. 6. A three-dimensional image capturing device, comprising:a plurality of laser devices that radiate pulse modulated laser beams irradiating a measurement subject for a distance measurement, said plurality of laser devices being separated into predetermined groups having plural laser devices;an imaging device that accumulates a signal charge corresponding to a quantity of light received at said imaging device;a signal charge accumulation control processor that controls an accumulating operation of the signal charge generated in said imaging device due to a reflected light beam of said laser beam, which is reflected by said measurement subject;a signal charge integrating processor that repeatedly drives said signal charge accumulation control processor, so that said signal charge accumulated in said imaging device is integrated; anda laser emitting operating processor that controls said laser devices to radiate laser beams concurrently in each of said predetermined groups, wherein each of said laser devices in each of said predetermined groups is disposed at predetermined intervals, each illuminating area of said laser beam radiated from said each laser device overlapping each other at the distance of said measurement subject, wherein each of said predetermined groups comprises a pair of laser devices that are disposed opposite each other with a center of a photographing lens in between. 7. The device of claim 6, wherein said each group of laser devices radiates laser beams at a different timing. 8. The device of claim 6, wherein said plurality of laser devices is disposed at regular intervals along a periphery of a photographing lens in circular arrangement. 9. The device of claim 8, wherein at least one laser device of a predetermined group is disposed between said plural laser devices forming another predetermined group.
