Patent ID: 6973263

Claim:
A camera apparatus comprising an image projection apparatus including: a laser light source for generating light of diffused laser beams; a lens for converting said light of diffused laser beams to light of parallel laser beams; and a hologram plate irradiated with said light of parallel laser beams and integrated with said lens into one body unit, wherein said image projection apparatus projects onto an object a hologram reproduced image that is obtained by applying said light of parallel laser beams to said hologram plate, said camera apparatus performs an auto focusing operation by using a projected image of said hologram reproduced image projected onto said object, wherein the hologram reproduced image has at least a minimum contrast and exceeds minimum focus requirements; means for adjusting a quantity of laser light of the parallel laser beams by driving the laser light source according to a pulse signal having an arbitrary pulse width, and based on the presence or absence of a built-in flash device; arbitrary lighting means for adjusting the quantity of laser light of the parallel laser beams by controlling the pulse width of the pulse signal according to the quantity of light of the laser light source; and means for stopping the laser light source from generating the laser light when the means for adjusting the quantity of laser light of the parallel laser beams malfunctions.
