摘要： A manipulation input device includes a projection component, a photodetector and an inclination determination component. The projection component projects an image on a projection surface by scanning light from a light source. The photodetector detects as scattered light the light reflected by a manipulation object. The inclination determination component acquires, for a plurality of scan lines of the light, position information of the manipulation object that is specified based on scanning angle information when the photodetector has detected the scattered light, and width information of the manipulation object that corresponds to a continuous detection duration during which the photodetector continuously detects the scattered light. The inclination determination component determines inclination of the manipulation object based on at least one of a temporal change in a plurality of sets of the width information and a temporal change in a plurality of sets of the position information.

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 (22) onto a desk (20), and projects a main projection screen picture (32) to a wall (30). The projector (100) includes a light receiving element (170). The light receiving element (170) is arranged in a position where light emitted toward the desk (20) (VUI screen picture (22)) and reflected (or scattered) by an object (10) near the desk (20) enters. The projector (100) calculates a position of the object (10) based on light sensing timing by the light receiving element (170) and light scan positions at various points in time. The projector (100) changes a projected screen picture when it determines that object (10) is simultaneously in contact with a plurality of portions of the VUI screen picture (22) and at least one of contact positions moves.

摘要： When a position detector (209) detects that the position of a spot on a projection plane (230) 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 (204) 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 laser driver circuit (30r,30b,30g) comprising a current supply circuit (40-0) for supplying a laser diode (11r,11b,11g) with a current is provided. The current supply circuit comprises a voltage-to-current converter circuit (41-0), a current output line (42-0) for outputting the current generated by the voltage-to-current converter circuit, a current supply line connected to the laser diode, a ground line connected to the ground, and a current path switch for selectively connecting either the current supply line or the ground line to the current output line. The laser driver circuit further comprises a current output prevention circuit (60) for preventing the voltage-to-current converter circuit from generating the current by disconnecting the voltage input line using a voltage input switch so that the voltage is not input to the voltage-to-current converter circuit, when the current output line and the ground line are connected by the current path switch.

摘要： An optical pickup device includes a beam shaping mirror. The mirror has a first optical surface on which a wavelength selection film is formed and a second optical surface on which a diffraction grating is formed. The wavelength selection film transmits a first laser beam and reflects a second laser beam. Light intensity distribution of the first laser beam is converted from an elliptic shape to a circular shape by reflecting the first laser beam transmitted by the wavelength selection film and input to the beam shaping mirror by the diffraction grating, then transmitting it by the wavelength selection film and outputting it from the beam shaping mirror. The diffraction grating diffracts the first laser beam in order that directions of the first and second laser beams which are output from the beam shaping mirror become the same.
