Projector and method for controlling projector

A projector includes a control unit that, when an operation unit receives an operation of selecting an uppermost menu item belonging to an uppermost layer, displays a middle menu item belonging to a middle layer, and, when the operation unit receives an operation of selecting the middle menu item, displays a lowermost menu item belonging to a lowermost layer. While the lowermost menu item is displayed, when the operation unit receives a short-press operation, the control unit displays the middle menu item, and, while the lowermost menu item is displayed, when the operation unit receives a long-press operation, the control unit displays the uppermost menu item.

Image display apparatus, control method of image display apparatus, and program

A projector includes: an image interface unit; a projection unit which projects a projection image based on image information, onto a screen; a setting unit which sets an aspect ratio of the projection image; a projection control unit which causes the projection unit to project the projection image according to the aspect ratio set by the setting unit; and an EDID processing unit which causes first information about an aspect ratio of the image information to be transmitted to a PC. If the setting unit changes the aspect ratio of the projection image from a first aspect ratio to a second aspect ratio, the EDID processing unit causes the first information based on the second aspect ratio to be transmitted to the PC.

A projector includes a projection section that projects first light representing an image on a projection surface, a detection section that detects whether or not an enclosure member that encloses part of an area through which the first light projected via the projection section passes has been attached to the projector, and an adjustment section that adjusts the intensity of the first light based on the result of the detection performed by the detection section.

A projection system includes a projector and a light emitting device that emits detection light in a direction in response to a screen. The projector detects an operation to the screen based on detection light of the light emitting device by a position detection section and switches the light emitting device between an emission mode and a non-emission mode thereof in response to state of the projector.

A position detection device includes a detection section adapted to detect an operation to a screen, a detection control section adapted to identify the pointing element with which the operation is performed, and associate the operation with the pointing element, and a processing section adapted to process the operation associated with the pointing element out of the operations. In the case in which a first operation and a second operation, which is performed within a predetermined period of time before the first operation, with a single pointing element are detected, and a coordinate of the first operation and a coordinate of the second operation are located within a predetermined range, the detection control section treats the coordinate of the first operation as the same coordinate as the coordinate of the second operation. Further, the detection control section changes the predetermined range in accordance with the detection position in the screen.

A position detection device includes a detection section adapted to detect an operation to a screen, a detection control section adapted to discriminate the pointing element with which the operation is performed, and then associate the operation with the pointing element, and a processing section adapted to process the operation associated with the pointing element out of the operations. In the case in which a first operation and a second operation, which is performed within a predetermined period of time before the first operation, with a single pointing element are detected, and a coordinate of the first operation and a coordinate of the second operation are located within a predetermined range, the detection control section determines the coordinate of the first operation as the same coordinate as the coordinate of the second operation. Further, the detection control section changes the predetermined range in accordance with the pointing element.

When image data which does not satisfy set conditions is input from a device which outputs image data, a display apparatus prevents a distortion of display. The display device includes a display unit that displays an image based on image data input from the PC, a connection control unit that executes connection control of setting transmission conditions including transmission line capacity of the image data to be output from the PC by transmitting and receiving control information to and from the PC, an input data determination unit that determines whether or not the image data to be input from the PC satisfies the transmission conditions, after the connection control, and a display control unit that sets a display state with the display unit as a predetermined display state, when it is determined that the image data to be input from the PC does not satisfy the transmission conditions.
