Abstract: A projector is provided with a CPU, a first memory which is a volatile memory to be reset when the projector makes the transition to a standby state, and a second memory which is a volatile memory capable of keeping data in the standby state of the projector. The CPU stores OSD data in the second memory when the projector makes the transition to the standby state.

Abstract: A display device comprising a first interface receiving a first image, a second interface receiving a second image, and at least one processor executing, generating a first composite image including the first image and a part of the second image, and displaying the first composite image on a display surface, the first composite image including a first area, and a first superimposition area that is a different part from the first area and that includes the part of the second image, the first superimposition area being superimposed on the part of the second image displayed by another display device at the display surface.

Abstract: A display control method includes: acquiring a standard time; synchronizing an internal time referred to in processing by one display device with the standard time; detecting a reference time, which is the internal time when an image represented by an input image signal satisfies a predetermined condition; outputting the reference time to another display device of a plurality of display devices; acquiring a reference time detected in the another display device; and delaying a vertical synchronization signal by a time period from the reference time of the one display device to the reference time of the another display device, when the reference time of the another display device is later than the reference time of the one display device.

The CPU stores OSD data in the second memory when the projector makes the transition to the standby state.

Abstract: An image processing apparatus includes a first image processing circuit and a second image processing circuit connected to the first image processing circuit via a first signal line and a second signal line. The first image processing circuit outputs OSD image data representing an OSD image in the form of n sets of divided OSD image data that are generated by dividing the OSD image data by n to the second image processing circuit via the first signal line and outputs position information of the divided OSD image data to the second image processing circuit via the second signal line. The second image processing circuit outputs, based on first input image data, the n sets of divided OSD image data, and the position information, combined image data representing a combined image formed of the first input image on which the OSD image is superimposed.

Abstract: A projector includes a light source portion and a light modulation device which modulates light from the light source portion. The projector includes an entire control processor which controls an operation of the projector by executing an OS, and a video-output system processor which is operated in parallel to the entire control processor and controls a light source of the light source portion and the light modulation device. The projector includes a nonvolatile storage unit which stores control data processed by the video-output system processor. The entire control processor transmits the control data stored in the nonvolatile storage unit to the video-output system processor before activating the OS.

Abstract: A projector includes: a first processor that controls the projector; a second processor that controls the light source; and a storage unit that stores parameters for the second processor to control the light source. The second processor starts to control the light source based on the parameters stored in the storage unit when activated. When the parameters are changed, the first processor stores the changed parameters in the storage unit.
