A method for controlling a display device displaying a horizontally oriented image or a vertically oriented image includes: determining whether the display device is in a state of displaying the horizontally oriented image or in a state of displaying the vertically oriented image; transmitting first resolution information representing a first resolution to a terminal device when it is determined that the display device is in the state of displaying the horizontally oriented image, and transmitting second resolution information representing a second resolution higher than the first resolution to the terminal device when it is determined that the display device is in the state of displaying the vertically oriented image; receiving image information with a resolution based on the first resolution information or the second resolution information from the terminal device; and displaying the image based on the image information.

A projector includes a video processing section configured to generate a third image by combining, on the basis of transmittance, a first image based on first image information and a second image generated by converting luminance information of second image information including the luminance information into the transmittance and an image forming section configured to display the third image.

A system displays an image using a plurality of projection type display devices, and is capable of reliably notifying a user who uses the system that an error has occurred in a certain projection type display device. A slave includes a display unit that projects and displays an image and a signal receiving unit that receives data transmitted from a commander. The slave includes a detection unit that detects an error in the commander on the basis of the receiving conditions of the data in the signal receiving unit. The slave includes a display control unit that, when an error is detected by the detection unit, makes the display unit display an image showing that the error has been detected.

Projection type display device, display system, and display method

A projection system performs projection on a projection surface using a plurality of projectors including a first projector and a second projector. The projection system projects, using the first projector, a first guide in a position a predetermined amount of a margin spaced apart from a border of a projection region where an image is projected and projects, using the second projector, a second guide distinguishable from the first guide.

Projection system and projector

In the case where a projector is used in combination with another projector, individual use of only one projector is enabled. A slave projector operates together with a master projector. In this case, the operation methods to start up the projector are a first method in which only a first key is pressed, a second method in which the first key and a second key are pressed simultaneously, and a third method in which the first key and a third key are pressed simultaneously. When the slave projector detects a user's operation with a remote controller, if the operation is done by the first method or the second method, the slave projector ignores this operation. Meanwhile, if the operation is done by the second method, the slave projector starts up the own device irrespective of the command from the master.

A projector that performs projection in cooperation with another projector, the projector including a determining unit configured to determine an operation state of the other projector and a control unit configured to control the projector to shift to, when the determining unit determines that the operation state of the other projector is not a normal operation state, a limited operation mode for limiting execution of at least a part of functions.

A display system displays images projected by a plurality of projection type display devices so as to overlap each other. When a user uses this system, events occurring in these devices can be reliably delivered to the user. A commander and a slave project and display images so as to overlap each other. When a notification-required event occurs in the commander or the slave, the commander specifies this notification-required event. Then, the commander displays a first OSD image between the first OSD image and a second OSD image, which form an image corresponding to the specified notification-required event, in a predetermined region of a first screen of screens on which images are displayed. Also, the commander outputs to the slave a control signal to display the second OSD image in the predetermined region. The slave displays the second OSD image in the predetermined region when the control signal is received.

A projector includes: an image modulation section that modulates light emitted from a light source in accordance with a video signal to form an optical image; a projection section that enlarges and projects the optical image; a drawing area setting section that sets a drawing area within an image modulation area where the light is modulated to form the optical image, the drawing area being an area where a template image is drawn; and a template image generating section that generates the template image to be drawn in the drawing area.
