View Patent ↗A display device displays a guidance display for guiding a control operation on a display screen when receiving the control operation. The display device includes an operation source determination part that determines a source of the control operation based on the control operation received and a guidance display generator that, according to the determined source, displays the guidance display corresponding to the source on the display screen.
1. A display system that displays a guidance display for guiding a control operation on a display screen when receiving the control operation, the display system comprising:
a display device comprising:
an operation source determination part that determines whether a source of the control operation is a first source or a second source, based on the control operation received; and
a guidance display generator that:
displays, on the display screen, a first guidance display corresponding to the first source, in response to a determination that the source of the control operation is the first source,
displays, on the display screen, a second guidance display different from the first guidance display and corresponding to the second source, in response to a determination that the source of the control operation is the second source; and
a projector including the display device, the projector comprising:
a key panel provided on a main body of the projector,
wherein the first source is a remote controller,
the second source is the key panel,
the first guidance display, displayed on the display screen, includes a layout image showing a layout of keys of the remote controller, and
the second guidance display, displayed on the display screen, includes a layout image showing a layout of keys of the key panel.
2. The display system according to claim 1 , wherein the control operation includes a main body operation performed by a key installed on a main body of the display device.
3. The display system according to claim 1 , wherein the control operation includes a controller operation performed by a controller disposed away from the display device.
4. The display system according to claim 3 , wherein the controller operation is performed from a first controller or a second controller having a key layout different from a key layout of the first controller.
5. The display system according to claim 1 , wherein the guidance display includes a layout image showing a layout of an operation key used for the control operation.
6. The display system according to claim 3 , wherein
the guidance display includes a layout image showing a layout of an operation key used for operation, and
the layout image in the guidance display corresponding to the controller operation includes only a region where a navigation key in the controller is disposed.
7. The display system according to claim 1 , further comprising a notification part that notifies that the source of the control operation cannot be recognized by display when the source of the control operation cannot be recognized.
8. A display method in which a display system including a display device and a projector including the display device displays a guidance display for guiding a control operation on a display screen, the display method comprising:
an operation source determination step of determining whether a source of the control operation is a first source or a second source, based on the control operation received by the display device;
a guidance display generation step of:
displaying, on the display screen, a first guidance display corresponding to the first source, in response to a determination that the source of the control operation is the first source, and
displaying, on the display screen, a second guidance display different from the first guidance display and corresponding to the second source, in response to a determination that the source of the control operation is the second source; and
wherein a key panel is provided on a main body of the projector,
the first source is a remote controller,
the second source is the key panel,
the first guidance display, displayed on the display screen, includes a layout image showing a layout of keys of the remote controller, and
the second guidance display, displayed on the display screen, includes a layout image showing a layout of keys of the key panel.
9. A non-transitory computer-readable recording storage medium configured to store a program, which when executed by a central processing unit (CPU) of a display device included in a projector causes, in order to display a guidance display for guiding a control operation on a display screen by the display device, the CPU in the display device to execute steps comprising:
an operation source determination step of determining whether a source of the control operation is a first source or a second source, based on the control operation received by the display device; and
a guidance display generation step of:
displaying, on the display screen, a first guidance display corresponding to the first source, in response to a determination that the source of the control operation is the first source, and
displaying, on the display screen, a second guidance display different from the first guidance display and corresponding to the second source, in response to a determination that the source of the control operation is the second source,
wherein a key panel is provided on a main body of the projector,
the first source is a remote controller,
the second source is the key panel,
the first guidance display, displayed on the display screen, includes a layout image showing a layout of keys of the remote controller, and
the second guidance display, displayed on the display screen, includes a layout image showing a layout of keys of the key panel.
