摘要： Disclosed is a projection image display apparatus to display an image by projecting a light from a light source to a screen including a scan mirror to scan the light from the light source by vibrating in a sine vibration manner at least in an one-dimensional direction and a correction lens which is disposed between the scan mirror and the screen and which corrects a deflection angle of the light scanned by the scan mirror at least in the one-dimensional direction, and the correction lens carries out a correction so that the larger a scan angle of the scan mirror is, the larger the deflection angle is to be by the correction.

摘要： A projector producing an imaginary input plane with high operability is provided. A projector according to an embodiment projects a VUI screen picture onto a desk, and projects a main projection screen picture to a wall. The projector includes a light receiving element. The light receiving element is arranged in a position where light emitted toward the desk (VUI screen picture) and reflected (or scattered) by an object near the desk enters. The projector calculates a position of the object based on light sensing timing by the light receiving element and light scan positions at various points in time. The projector changes a projected screen picture when it determines that object is simultaneously in contact with a plurality of portions of the VUI screen picture and at least one of contact positions moves.

摘要： A projector includes: a determination section to specify 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 to determine an amplification quantity of the intensity of a reflected light reflected at the specified reflection position to be received by the light receiving sensor; an amplification section to amplify the intensity of the reflected light received by the light receiving sensor by the determined amplification quantity; an identification section to identify an external obstacle when the intensity of the amplified reflected light exceeds a predetermined threshold value; and a calculation section to calculate 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.
