Input source search support method, and image display apparatus and projector using the search support method

A source search method for image display apparatus for displaying an image produced by image signals on a display section, comprising:

• receiving requirement of search processing for determining whether the image signals have been inputted to each of input terminals;
• generating image signals for producing a source search screen indicating search status for each of input source names corresponding to the input terminals;
• displaying an image of the source search screen produced by the image signals at least on the display section in response to search processing requirement;
• and
• closing the source search screen and selecting one of the input terminals from which image signals have been detected first when processing for selecting any of image signal input sources is not executed after checking a presence or absence of image signals for all the input terminals.

An image display apparatus for displaying an image produced by image signals on a display section, comprising:

• an input selector for selecting a predetermined input terminal from a plurality of input terminals;
• an operating section which receives requirement of search processing for determining whether the image signals have been inputted to each of the input terminals;
• an image signal correcting section which generates image signals for producing a source search screen indicating search status for each of 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 in response to search processing required through the operating section, wherein:
• the control section commands the image signal correcting section to close the source search screen and commands the input selector to select an initial input terminal from a plurality of input terminals when it is determined that no image signal is inputted in any of the input terminals and processing for selecting any of image signal input sources is not executed through the operating section after checking a presence or absence of image signals for all the input terminals.
