Image processing method and image processing device

A control method for a display device includes, in a state in which first firmware is installed, acquiring version information of second firmware installed in another display device from the other display device, inquiring the other display device about propriety of update of the second firmware to the first firmware when a version of the second firmware is older than a version of the first firmware, receiving the second firmware from the other display device when a notification for denying the update of the second firmware is received from the other display device, and updating the first firmware installed in the display device to the second firmware.

Operating display devices in association with each other using older firmware

A display control method includes displaying a first small image generated by shrinking a first image generated by an application program, on an actual display provided in an output device, receiving an operation on the first small image, drawing, on a virtual display, a second image generated by the application program executing processing corresponding to the operation on the first small image, displaying the second image drawn on the virtual display, using a display device, and displaying a second small image generated by shrinking the second image, on the actual display.

Display control method and non-transitory computer-readable storage medium storing program for having a virtual display relating to an actual display

An image processing method includes displaying a first screen on a display surface, the first screen including at least a part of a drawing area in which at least one object image drawn by a user is arranged, excluding an area in which at least a part of an object image included in the first screen is arranged from the drawing area when an operation of erasing the at least a part of the object is received, and displaying a reduced screen on the display surface when an operation is received, the reduced screen being obtained by reducing a whole of the drawing area into a size of the display surface.

A method for controlling a projecting system is provided. The method includes: causing a projector projecting a menu screen onto a screen to store definition information defining the menu screen; causing the information processing device to generate update information used to update the definition information; causing the information processing device to transmit the update information to the projector; causing the projector generating an updated definition information, based on the update information; by updating the definition information and causing the projector to generate the menu screen, based on the updated definition information.

Method for controlling projecting system, projecting system, and projector

A screen generation method includes setting a first degree of priority for a first terminal, setting a second degree of priority for a second terminal, receiving first image data representing a first image from the first terminal via a first communication link, receiving second image data representing a second image from the second terminal via a second communication link, transmitting a degree-of-priority notification notifying the first degree of priority or the second degree of priority to at least one of the first terminal or the second terminal to control traffic of the first image data and. the second image data so as to correlate with a relationship of the first degree of priority and the second degree of priority, generating a display screen including the first image and the second image, based on the first image data and the second image data, and when a disconnection of one of the first communication link or the second communication link occurs, changing the first degree of priority or the second degree of priority after a first time period from the occurrence of the disconnection.
