Abstract

It is arranged that the portal screen can be displayed or can be prevented from being displayed depending on needs. A projector includes an input section adapted to input a video signal, a determination section adapted to determine whether or not a portal screen, which includes at least one of information related to projection and a plurality of selection items, needs to be displayed based on presence or absence of a video signal input by the input section at the time of startup, and a projection section adapted to project either of a picture corresponding to the video signal and the portal screen in accordance with a determination result by the determination section.

Claims

1. A projector comprising:

an input section adapted to input a video signal;

a determination section adapted to determine whether or not a portal screen, which includes at least one of information related to projection and a plurality of selection items, needs to be displayed based on presence or absence of a video signal input by the input section at the time of startup; and

a projection section adapted to project either of a picture corresponding to the video signal and the portal screen in accordance with a determination result by the determination section.

2. The projector according to claim 1, wherein

the input section inputs the video signal supplied from an active input source among a plurality of input sources, and

in a case in which the video signal fails to be input from the active input source, the determination section determines that the portal screen is to be displayed.

3. The projector according to claim 2, wherein

in a case in which the input of the video signal from the active input source is broken, the projection section continues to project the picture, which has been projected immediately before the input is broken, and

in a case in which a predetermined time has elapsed from when the input of the video signal from the active input source has been broken, the determination section determines that the portal screen is to be displayed.

4. The projector according to claim 1, further comprising:

a selection section adapted to select either of the selection items having been displayed in the portal screen in accordance with an operation by the user; and

a process execution section adapted to execute a process corresponding to the selection item having been selected by the selection section,

wherein in a case in which the selection by the selection section fails to be fixed and a predetermined condition is fulfilled, the determination section determines that the portal screen is to be displayed.

5. The projector according to claim 4, wherein

the projection section projects the portal screen in which either of the selection items is pointed by a cursor, and

the determination section determines that the portal screen, in which the selection item corresponding to an operation of the user in a case in which the predetermined condition has been fulfilled is pointed by the cursor, is to be displayed.

6. The projector according to claim 1, wherein

the input section inputs either of the video signals supplied from a plurality of input sources, and

in a case in which the video signals are simultaneously supplied from two or more of the input sources, the determination section determines that the portal screen is to be displayed.

7. The projector according to claim 1, wherein

the portal screen includes at least

a region in which projector information is displayed,

a region in which a variety of guides of an operation are displayed, and

a region in which information related to the input source is displayed.

8. The projector according to claim 7, wherein

the projector information is information related to network connection of the projector.

9. The projector according to claim 7, wherein

a link for displaying the manual is disposed in the region in which the variety of guides of the operation are displayed.

10. A display device comprising:

an input section adapted to input a video signal;

a determination section adapted to determine whether or not a portal screen, which includes at least one of information related to display and a plurality of selection items, needs to be displayed based on presence or absence of a video signal input by the input section at the time of startup; and

a display section adapted to display either of a picture corresponding to the video signal and the portal screen in accordance with a determination result by the determination section.

11. A display method of a display device, comprising:

determining, at the time of startup, whether or not a portal screen, which includes at least one of information related to display and a plurality of selection items, needs to be displayed based on presence or absence of a video signal input; and

displaying either of a picture corresponding to the video signal and the portal screen in accordance with the determination result.
