Image display apparatus having image-related information displaying function

Abstract

In an electronic apparatus having a user identification function or in a user identification method, an electronic apparatus and an electronic instrument having stored therein user personal information communicate in wireless with each other so as to enable the electronic apparatus to automatically identify the electronic apparatus user. If the electronic apparatus identifies a plurality of possible users, the electronic apparatus automatically selects the user by 10 executing specific user identification processing

What is claimed is: 
     
         1 . An image display apparatus, comprising:
 a read unit that reads out an image file in which image data obtained by photographing a subject within a photographic image plane and subject information made to correlate to a position of the subject within the photographic image plane and related to the subject are stored;   an image display unit that displays the image contained in the image file at a display screen;   a position specification unit that specifies a position on the display screen at which the image data are displayed; and   an information display unit that displays subject information made to correlate to a position within the photographic image plane corresponding to the position specified through the position specification unit.   
     
     
         2 . An image display apparatus according to  claim 1 , wherein:
 the position specification unit is a pointing device operated by a user.   
     
     
         3 . An image display apparatus according to  claim 2 , wherein:
 the pointing device is constituted of a touch tablet used for position specification which is installed on the display screen and allows light to be transmitted, detects a position of a subject displayed at the display screen which is specified by the user with a finger or another member, and specifies a position at the display screen in correspondence to the detected position.   
     
     
         4 . An image display apparatus according to  claim 1 , wherein:
 the position specification unit is a sight line detection unit that detects a position of the line of sight of a user relative to the display screen.   
     
     
         5 . An image display apparatus according to  claim 1 , wherein:
 the subject information includes access information with regard to an information source on a network having stored therein detailed information on the subject; and   the information display unit obtains, through a network communication, the detailed information on the subject from the information source on the network indicated by the access information included in the subject information and displays the obtained information.   
     
     
         6 . An image display apparatus according to  claim 1 , wherein:
 the image display unit and the information display unit share a common display screen; and   the information display unit displays reduced image data over an area constituting part of the display screen when displaying the subject information at the display screen.   
     
     
         7 . An image display apparatus according to  claim 1 , wherein:
 the subject information includes audio information.
