  • Patent number: 10491871
    Abstract: A projector includes an input unit configured to receive an image signal, a display configured to display an image based on the image signal received by the input unit, an image displacement unit configured to change a position of the image to be displayed by the display, and a control unit configured to control a driving signal to drive the image displacement unit. An output timing of the driving signal is changed based on a frequency of the image signal.

  • Patent number: 10122979
    Abstract: A projector includes: an I/F unit to which an image signal is input; a display unit that displays an image based on the image signal input to the I/F unit; a shift device that changes a position of an image to be displayed by the display unit; a signal processing unit that outputs a driving signal to the shift device and drives the shift device; and a shift control unit that controls the driving signal output by the signal processing unit. The shift control unit changes an output timing of the driving signal to correspond to a change in a frequency of the image signal.

  • Patent number: 8132925
    Abstract: A projector includes: a light source; a light modulation device which modulates a light emitted from the light source and forms image light; a projection device which magnifies and projects the image light; and an exterior casing, wherein on a light exiting surface for the image light of the exterior casing, a first opening is formed and a projection direction change unit which opens and closes the first opening is provided, and the projection direction change unit has: a cover which has a second opening for passing the image light from the projection device and which is provided rotatably in an off-plane direction with respect to the light exiting surface and thus opens and closes the first opening; a shutter which is movably provided along an inner surface of the cover and thus opens and closes the second opening; and a reflection mirror which is provided on an inner surface of the shutter and reflects the image light from the projection device.
