Abstract
Abstract An image display apparatus includes a moving device for moving desired data on an image recording medium, on which image data and index data are recorded, to a read-out position, and a reader for reading data located at the read-out position and generating an electric signal corresponding to the read-out data. A memory stores data read by the reader and includes a first memory for storing image data and a second memory for storing index data. In addition, a display selectively displays data stored in one of the first and second memories.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
An image display apparatus, comprising: moving means for moving a recording medium to locate a selected area on the recording medium to a read-out position, the recording medium having a plurality of image areas on which image data is recorded and index areas on which index data for retrieving the image data of each image area is recorded; reading means for reading the data of the selected area on the recording medium located at the read-out position and generating an electric signal corresponding to the read data; memory means for storing the data read by said reading means, with said memory means being capable of storing data from the image areas and the index areas; display means for displaying data stored in said memory means; first designating means for designating index data stored in said memory means to be displayed by said display means; second designating means for designating an address of a desired image area, with the address being obtained by the index data displayed by designation of said first designating means; and control means for controlling said moving means to locate the image area corresponding to the address designated to said second designating means to the read-out position.
Claim 2
Dependent Claim
