Input source search support method, and image display apparatus and projector using the search support method
First Claim
1. A projector comprising:
- a light source;
a plurality of input terminals;
at least one light modulating element adapted to modulate light from the light source based on an image signal;
an optics adapted to project light modulated by the at least one light modulating element;
an input selector adapted to select a predetermined input terminal from the plurality of input terminals;
a judging section adapted to determine for each of the plurality of input terminals whether the image signal is inputted to the input terminal, including the input terminal selected by the input selector; and
a control section adapted to command the input selector to select an initial input terminal defining an input terminal that is first judged by the judging section from the plurality of input terminals when the judging section has determined that no image signal is inputted to any of the plurality of input terminals after elapse of a predetermined time, whereinthe control section controls the at least one light modulating element to modulate light from the light source to project an image indicating a name of the input terminal which is being judged whether the image signal is inputted and, after judging that no input signal is input to any of the plurality of input terminals, projecting a message that none of the plurality of input terminals has an input signal input thereto.

Abstract
An image display apparatus for displaying an image produced by image signals on a display section includes: a plurality of input terminals for receiving each of the image signals supplied from a plurality of input sources; an input selector for selecting a predetermined input terminal from the plural input terminals; a judging section for determining whether the image signals have been inputted to the input terminal selected by the input selector; an operating section which receives requirement of search processing for determining whether the image signals have been inputted to each of the plural input terminals; an image signal correcting section which generates image signals for producing a source search screen indicating search status for each of the input source names corresponding to the input terminals; and a control section for displaying an image of the source search screen produced by the image signals at least on the display section.

6. A source search method for a projector which includes a light source, a plurality of input terminals, at least one light modulating element adapted to modulate light from the light source based on an image signal, an optics adapted to project light modulated by the at least one light modulating element, the method comprising:
-
selecting a predetermined input terminal from the plurality of input terminals; determining for each of the plurality of input terminals whether the image signals is inputted thereto, including the selected input terminal; and selecting an initial input terminal defining an input terminal that is first judged by the judging section from the plurality of input terminals when it has been determined that no image signal is inputted to any of the plurality of input terminals after elapse of a predetermined time, wherein, the at least one light modulating element modulates light from the light source to project an image indicating a name of the input terminal which is being determined whether an image signal is inputted and, after judging that no input signal is input to any of the plurality of input terminals, projecting a message that none of the plurality of input terminals has an input signal input thereto. - View Dependent Claims (7, 8, 9)
