A projector includes a projection section that projects a first image on a projection surface, a control section that causes the projection section to project a pattern image for installation including a first pattern that is located at an end of the first image, which overlaps with a second image, and a second pattern that is so disposed that a first straight line section is located in a position separate from the end by a distance, and a correction section that corrects the first image based on a captured image containing an image of a first area of the second image, and the first area is an area that overlaps with an area having a width corresponding to the distance measured from the end of the first image in a state in which the first image and the second image overlap with each other.

Projector, image projection system, and method for controlling projector

A control method for a projector includes coupling a projector to another projector, transmitting first instruction information representing a start of setting of stack projection using the projector and the other projector to the other projector by the projector, setting a first projection range indicating a range in which the projector projects an image for the stack projection, and transmitting second instruction information representing adjustment to make a second projection range indicating a range in which the other projector projects an image coincide with the first projection range to the other projector by the projector.

Control method for projector, projector, and image projection system

A method for controlling a projector, the method comprising: determining, when the projector having an RF tag is started up, whether a setting that permits a process of reading out setting information stored in the RF tag and configuring a setting on the projector based on the setting information is configured or not; determining whether a password requested to be inputted to an information processing device is at an initial value or not, when the setting information is written into the RF tag from the information processing device; and notifying a user of a warning message when it is determined that the setting that permits the process is configured and it is determined that the password is at the initial value.

Method for controlling projector, projector, and display system

The projector executes a detection step of detecting a rotational angle of the projector with respect to a horizontal direction, a determination step of determining a correction parameter of correcting a shape of an image to be projected based on the rotational angle detected, a correction step of correcting the shape of the image based on the correction amount determined in the determination step, and a projection step of projecting the image corrected in the correction step. In the determination step, a range of the installation angle at which the projector is installed is divided into a plurality of areas, which of the areas the rotational angle detected in the detection step belongs to is determined, and the correction parameter is determined based on a difference between the reference angle set in the area to which the rotational angle is determined to belong and the rotational angle detected.

Method of controlling projector and projector

A projector selects an image of a home screen as an image to be displayed by a display section even when input of an image signal to the interface section is detected when the home screen has been displayed on the grounds that an operation has been received by a remote controller or an operation panel, and changes the image to be displayed by the display section from the image of the home screen to the image based on the image signal the input of which has been detected when the input of the image signal to the interface section is detected when the home screen has been displayed on the grounds that no input of the image signal to the interface section has been detected.

Display device and method of controlling a display mode of the display device to selectively display a selection screen and an image screen

A projector includes a selection section configured to select an interface to which an image signal to be displayed by the projector out of the plurality of interfaces is input, a determination section configured to determine whether or not the interface selected is a compliant interface capable of establishing daisy chain connection, and a function control section configured to make the transition of the projector to a state of preventing a daisy chain function from being executed when the interface selected is not the compliant interface, and when the daisy chain function which can be executed in a state in which the projector is coupled to another projector with the daisy chain connection is set available.

Method of controlling display device, and display device

A method of controlling a display device according to the present disclosure includes the steps of executing input determination on whether or not the image information is input to the input interface, making the display section display an input state image including one of an input image representing that the image information is input and a non-input image representing that the image information is not input in accordance with a result of the input determination, making the display section display a display image based on the image information when receiving an operation of designating the input image, and making the display section display a procedure image representing a procedure of inputting the image information to the input interface when receiving an operation of designating the non-input image.

Method of controlling display device and display device

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 projection section that displays an image based on image information, a communication section that communicates with another projector, an input operation section that accepts operation for executing a light source color adjustment process, a light source color adjustment section that executes the light source color adjustment process based on the operation accepted by the input operation section, and a control section that causes the communication section to transmit, based on the operation accepted by the input operation section, control information that causes the other projector to perform the light source color adjustment process to the other projector.

Image display apparatus, image display system, and method for controlling image display apparatus

A projector includes a light source section that outputs first light, a power supply section that generates electric power in both a case where the power supply section is connected to a commercial AC power supply having first power supply voltage and a case where the power supply section is connected to a commercial AC power supply having second power supply voltage lower than the first power supply voltage, a light source drive section that controls the amount of first light, and a control section that allows execution of a function of controlling the amount of first light in the case where the power supply section is connected to the commercial AC power supply having first power supply voltage and restricts the execution of the function in the case where the power supply section is connected to the commercial AC power supply having second power supply voltage.
