摘要： A projector includes a determination section, an amplification section, an identification section and a calculation section. The determination section specifies a reflection position of a reflected light received by a light receiving sensor based on a horizontal synchronizing signal and a pixel clock signal of an image signal, and determines an amplification quantity of the intensity of a reflected light reflected at the specified reflection position to be received by the light receiving sensor. The amplification section amplifies the intensity of the reflected light received by the light receiving sensor by the determined amplification quantity. The identification section identifies an external obstacle when the intensity of the amplified reflected light exceeds a predetermined threshold value. The calculation section calculates the position information of the external obstacle based on the timing of identifying the external obstacle, the horizontal synchronizing signal, and the pixel clock signal of the image signal.

摘要： A laser projector can generate a pulse signal capable of being generated according to the resolution of the clock signal, the pulse signal having a basic period and a basic pulse width each infinitely approximated to the characteristics of the resonance frequency. Moreover, because the laser projector can generate a pulse signal capable of correcting the errors led to be included in the approximated pulse signal, the laser projector can drive the scanning section with a horizontal vibration width corresponding to the resonance frequency, and can suitably display a projected image on a projection plane.

摘要： In an optical pickup apparatus, a collimator lens is rockably supported by edges of two protruding portions formed on opposing sides of a groove of an optical base. The collimator lens is urged against the edges of the two protruding portions by a leaf spring. The position in vertical direction of one end of the leaf spring is adjusted by a position adjustor. In this manner, a tilt angle of the collimator lens is adjusted. Therefore, astigmatism of the light spot can precisely be compensated for irrespective of variations among apparatuses to achieve an excellent light spot.
