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 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 3
Dependent Claim 25 words
The image display apparatus according to claim 1, wherein said moving means includes transfer means for transferring the recording medium in X and Y directions.
Claim 4
Dependent Claim 38 words
The image display apparatus according to claim 2, further comprising optical means for projecting an image on the image recording medium onto said reading means and drive means for driving said optical means along the image recording medium.
Claim 5
Dependent Claim 29 words
The image display apparatus according to claim 1, wherein the image recording medium is a microfiche, and index data is recorded on at least one frame of the microfiche.
Claim 6
Dependent Claim 183 words
A retrieval apparatus which uses a film having a plurality of frames on which image information is recorded and frames on which index information for retrieving the image information of each of the plurality of frames is recorded, comprising: reading means for reading information recorded on the frame located in a read-out position; moving means for moving the film to locate a selected frame to the read-out position; memory means having a first memory for storing index information read by said reading means and a second memory for storing at least one image information read by said reading means; display means for displaying information 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 image information to be retrieved, with the address being obtained form the index information displayed by said display means; and control means for controlling said moving means to locate the image information to be retrieved corresponding to the designation by second designating means to the readout position.
Claim 7
Dependent Claim 183 words
A retrieval apparatus which uses a film having a plurality of frames on which image information is recorded and frames on which index information for retrieving the image information of each of the plurality of frames is recorded, comprising: reading means for reading information recorded on the frame located in a read-out position; moving means for moving the film to locate a selected frame to the read-out position; memory means having a first memory for storing index information read by said reading means and a second memory for storing at least one image information read by said reading means; display means for displaying information 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 image information to be retrieved, with the address being obtained form the index information displayed by said display means; and control means for controlling said moving means to locate the image information to be retrieved corresponding to the designation by second designating means to the readout position.
Claim 8
Dependent Claim 135 words
A display apparatus for displaying information of a film having a plurality of frames on which image information is recorded and frames on which index information for retrieving image information of each frame is recorded, comprising: reading means for reading information recorded on the frame located in a read-out position; moving means for moving the film to locate a frame on the film to the read-out position; controlling means for controlling said moving means to start movement of the film when the film is located at a predetermined position and locate the frame containing index information to the read-out position; memory means having a first memory for storing index information read by said reading means and a second memory for storing the read image information; and display means for displaying information stored in each memory.
Claim 9
Dependent Claim 135 words
A display apparatus for displaying information of a film having a plurality of frames on which image information is recorded and frames on which index information for retrieving image information of each frame is recorded, comprising: reading means for reading information recorded on the frame located in a read-out position; moving means for moving the film to locate a frame on the film to the read-out position; controlling means for controlling said moving means to start movement of the film when the film is located at a predetermined position and locate the frame containing index information to the read-out position; memory means having a first memory for storing index information read by said reading means and a second memory for storing the read image information; and display means for displaying information stored in each memory.
Claim 10
Dependent Claim 11 words
