For example, some cameras capture infrared wavelengths of 750 nm and other cameras capture infrared wavelengths of 850 nm. If infrared emitters that capture 750 nm are only utilized, then some cameras that capture infrared wavelengths of 850 nm, but not 750 nm, may avoid capturing the infrared overlay image 110. The wavelengths may or may not overlap. Accordingly, dissimilar wavelengths may be utilized in that the wavelengths may be incongruent. Accordingly, various infrared emitters may be utilized to capture a variety of different wavelengths that may be captured by different camera devices. As an example, an arrangement of 750 nm, 850 nm) and the second light beam is greater than or equal to 780nm and less than or equal to 1000nm (see para.

Then, the control unit turns off the infrared light source based on the detection signal).
It would have been obvious to one of ordinary skill in art before the effective filling date of the claimed invention to modify Ito in view of Wang, Joseph, Chang and Li with the teaching of Inuzuka so that a sensing element electrically connected to the processing element, receiving at least one of the visible image light beam reflected by a projection target and the IR image light beam to obtain a sensing result, and the processing element turns on or off the plurality of first IR light-emitting elements according to the sensing result to enhance the safety of the projection display device by reducing the IR output when a person is too close.
Claim(s) 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ito (United States Patent Application Publication 2008/0180640 A1) in view of Wang (CN 208126092 A), Joseph (United States Patent Application Publication 2012/0138821 A1), Chang (US 2012/0044461 A1), Li (CN 104076914 A), Inuzuka (JP 2002274258 A) and Nagasawa (United States Patent Application Publication 2014/0098349).
With respect to claim 20, Ito in view of Wang, Joseph, Chang, Li and Inuzuka discloses the IR light source module of claim 19, Ito in view of Joseph, Wang, Chang, Li and Inuzuka discloses the visible light source module comprises a red laser, a green laser, and a blue laser (see Chang: para.[0026]: Alternatively, the first light source device 31 comprises a red laser light source, a green laser light source and a blue laser light source, which emit the red light R, the green light G and the blue light B respectively by a time sequence control), but does not disclose wherein the plurality of first emitting elements and the plurality of second light-emitting elements are alternately arranged on the at least one circuit substrate or wherein the lasers are laser diodes.
Nagasawa discloses wherein the plurality of first emitting elements and the plurality of second light-emitting elements are alternately arranged on the at least one circuit substrate (see para.[0072]:For example, when the light source unit is made of four chips consisting of 2 chips for one color and 2 chips for another color, if the different LED light sources are alternately arranged in a rectangular geometry, the optical axes of the light sources of the colors are substantially coincident with the optical axis of the capture lens.) and wherein the lasers are laser diodes ([0030]: In addition, the light sources may also be solid-state light-emitting devices other than LEDs such as laser diodes emitting visible light.).
It would have been obvious to one of ordinary skill in art before the effective filling date of the claimed invention to modify Ito in view of Wang, Joseph, Chang, Li and Inuzuka with the teaching of Nagasawa so that the lasers are laser diodes and so that the plurality of first IR light-emitting elements and the plurality of second IR light-emitting elements are alternately arranged on the at least one circuit substrate to make the light source more compact and reduce input power by utilizing laser diodes instead of lasers and to make the light source more compact by providing two pluralities of light source on the same circuit; furthermore, it would have been obvious to one of ordinary skill in the art at the time the invention was made to modify Ito in view of Wang and Joseph with the teaching of Nagasawa so that the plurality of first IR light-emitting elements and the plurality of second IR light-emitting elements are alternately arranged on the at least one circuit substrate, since it has been held that rearranging parts of an invention involves only routine skill in the art.
