摘要： When a position detector detects that the position of a spot on a projection plane designates a non-projection region, the level of a driving signal of a laser is corrected. Specifically, the correlation between the quantity of laser light detected by a light-receiving portion and the level of the driving signal of the laser in accordance with prescribed data is detected. Then, the characteristic value of the laser indicated by the detected correlation is compared with the characteristic value at room temperature stored beforehand to indicate the correlation between the quantity of light emitted by the laser at room temperature and the level of the driving signal. Then, based on the comparison result, the level of the driving signal of the laser in accordance with image data is corrected.

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： A projector divides and projects a single image onto two different projection surfaces and performs virtual user interface through one projection surface. The projector projects a VUI screen image on a desk and projects a main projected screen image on a wall. The projector includes a light receiving element, which is installed at a position that receives light emitted to the desk (the projection surface of the VUI screen image) and reflected (or scattered) by an object in the vicinity of the desk. The projector calculates a position of the object based on a light detection timing of the light-receiving element and a scanning position of light at each time and changes a projected image based on the calculated position. The projector displays a designated region of the VUI screen image to be brightened.
