Patent ID: 7701452

Claim:
An image display apparatus for displaying an image produced by image signals on a display section, comprising: 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 in response to search processing required through the operation section; the control section commanding the input selector to sequentially select the input terminals when the search processing is required through the operation section, and commanding the judging section to check the presence or absence of the image signals inputted for each of the selected input terminals; the control section commanding the image signal correcting section to add an indication for each of the plurality of input sources that no image signal is inputted to any of the sequentially checked input terminals when no image signal is inputted thereto; the control section commanding the image signal correcting section to close the source search screen when it is determined that the image signals have been inputted to any of the input terminals, and commanding the display section to display an image produced by the image signals from the input terminal from which the image signals have been detected; the image display apparatus further including a storage section for storing an initial input terminal selected by the input selector before the search processing is required; and the control section commanding the image signal correcting section to close the source search screen and commanding the input selector to select the initial input terminal stored in the storage section when it is determined that no image signal has been inputted to any of the input terminals and processing for selecting any of the input sources is not executed through the operation section within a predetermined time.
