Abstract
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.
Claims9
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.
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.
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.
