Abstract: A projector is provided which divides and projects a single image onto two different projection surfaces and appropriately 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. The light-receiving element 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. The projector changes a projected image based on the calculated position. The projector displays a designated region of the VUI screen image (for example, a region including the position of the object or an icon display region or a region surrounding an icon) to be brightened.

Abstract: 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.

Abstract: 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.
