  • Patent number: 11800070
    Abstract: 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.

  • Patent number: 11770509
    Abstract: 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.

  • Patent number: 11457186
    Abstract: 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.

  • Publication number: 20220301120
    Abstract: 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.

  • Patent number: 11443712
    Abstract: 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.
