  • Patent number: 9389493
    Abstract: A projector, that projects an image, includes a light source, a liquid crystal panel that modulates light output from the light source and forms an image in response to input image data, a projection optical device that projects the image formed by the liquid crystal panel, a control device that controls the liquid crystal panel, and an acceleration sensor that detects a position of the projector. The control device includes a determination unit that determines whether or not the position detected by the acceleration sensor is a predetermined position, and a correction unit that corrects an orientation of the image data so that a longer side of the image data may coincide with a longer side of an image formation area of the liquid crystal panel if the determination unit determines that the detected position is the predetermined position.

  • Patent number: 9338415
    Abstract: A projector (1) which projects a guide image (Pg). A first region above the center of the guide image (Pg) shows a perspective view (D) representing the projector (1) and a supporting device (2) supporting the projector (1). A second region on the upper right of the guide image (Pg), shows six illustrations (G1-G6) affixed with numbers 1 to 6. The six illustrations (G1-G6) respectively correspond to six adjustment items related to a supporting state of the projector (1). The six illustrations (G1-G6) indicate how a projected image changes when the adjustment items are adjusted. The perspective view (D) is an explanatory diagram for clearly showing the positions of adjustment operation units that adjust the six adjustment items of the supporting device (2). In the perspective view (D), the numbers 1 to 6 are affixed near the respective adjustment operation units in balloons.

  • Publication number: 20150163468
    Abstract: In at least one embodiment, a projector includes a light source device, an optical modulation device, a projection optical device, and an operation button. The optical modulation device modulates a luminous flux emitted from the light source device in accordance with an image data to form an image. The projection optical device includes a reflecting mirror that projects the image from the optical modulation device toward a projection surface. An image opening allows the image projected from the projection optical device to pass through. The image opening is defined in a tilted surface of the projector exterior housing. The tilted surface is obliquely inclined relative to the projection surface. An operation button is disposed on another surface of the projector exterior housing. The other surface overlaps the reflecting mirror in plan view.
