Abstract

An image search apparatus includes a memory for storing plural sets of images, each set of the plural sets of images comprising one page image or plural page images, a display unit for displaying an image, and a control unit for controlling the display of the plural sets of images stored in the memory in reduced size on the display unit at a time, the control unit being capable of displaying desired pages of the said plural sets of images in reduced size.

Claims

1. An image retrieval apparatus for retrieving a desired image from a storage medium which stores a plurality of document files each comprising plural pages of images, comprising:

display means for simultaneously displaying respectively index images of the plurality of document files, the index image of each document file being a part or a reduced image of the image of each page of each document file;

input means for inputting one of a paging-back instructions for changing the displayed index image of one of the plurality of document files to the index images of the previous pages of the same document file and a paging-forward instruction for changing the displayed index image of the one of the plurality of document files to the index images of the next pages of the same document file; and

control means for selectively changing the displayed index image of the one of the plurality of document files to the index image of the previous or next page of the same document file according to the paging-back instruction or the paging-forward instruction inputted by said input means, while maintaining the displayed index images of the other document files.

2. An apparatus according to claim 1, wherein said input means is provided for each of the plurality of document files.

3. An apparatus according to claim 1, wherein said input means includes a pointing device for designating a desired position of said display means.

4. An image retrieval apparatus for retrieving a desired image from a storage medium which stores a plurality of document files each comprising plural pages of images, comprising:

display means for simultaneously displaying respectively index images of the plurality of document files, the index image of each document file being a part or a reduced image of the image of each page of each said document file;

designation means for designating one of the index images simultaneously displayed by said display means to select the document file corresponding to the designated index image;

input means for inputting a desired page of the document file selected by said designation means; and

control means for changing the simultaneously displayed index images of the document files to the index images of a predetermined number of pages from the desired page, inputted by said input means, of the same document file selected.

5. An apparatus according to claim 4, wherein said designation means includes a pointing device for designating a desired position of said display means.

6. An apparatus according to claim 4, further comprising second designating means for designating one of the index images of the same document file simultaneously displayed by said display means to select an original image of the designated index image, and

wherein said control means changes the index images simultaneously displayed by said display means to the original image selected by said second designation means to display said original image.

7. An apparatus according to claim 4, wherein said display means further displays the total number of pages of the document file by said designation means.

8. An apparatus according to claim 4, wherein said display means further displays the page number of the index image displayed by said display means.

9. An image retrieval apparatus for retrieving a desired image from a storage medium which stores a plurality of document files each comprising a plurality of pages of images, comprising:

display means for simultaneously displaying respectively index images of the plurality of document files, the index image of each document file being part or a reduced image of the image of each page of each said document file;

designation means for designating one of the index images simultaneously displayed by said display means to select the document file corresponding to the designated index image;

input means for inputting a desired page of the document file selected by said designation means; and

control means for changing the displayed index image of the document file selected by said designation means to the index image of the desired page inputted by said input means, of the same document file, to display the index image of the desired page of the same document file, while maintaining the displayed index images of the other document files.

10. An apparatus according to claim 9, wherein said control means changes the displayed index image of the selected document file to the index image of the desired page with the index images of the document files which have not been selected by said designation means being displayed unchanged.

11. An apparatus according to claim 9, wherein said designation means includes a pointing device for designating a desired position of said display means.

12. An apparatus according to claim 9, further comprising second designation means for designating the index image of the index images simultaneously displayed by said display means to select an original image of the designated index image, and

wherein said control means changes the index images simultaneously displayed by said display means to the original image selected by said second designation means to display the original image.

13. An apparatus according to claim 9, wherein said display means further displays the total number of pages of the document file selected by said designating means.

14. An apparatus according to claim 9, wherein said display means further displays the page number of the index image displayed by said display means.

15. An image retrieval method for retrieving a desired image from a storage medium which stores a plurality of document files each comprising a plurality of pages of images, comprising the steps of:

(a) simultaneously displaying respectively index images of a plurality of document files on a display, the index image of each document file being a part or a reduced image of the image of each page of each said document file;

(b) inputting one of a paging-back instruction for changing the displayed index image of one of the plurality of document files to the index images of the next pages of the same document file; and

(c) selectively changing the displayed index image of the one of the plurality of document files to the index image of the previous or next page of the same document file according to the input paging-back instruction or paging-forward instruction, while maintaining the displayed index images of the other document files.

16. An image retrieval method for retrieving a desired image from a storage medium which stores a plurality of document files each comprising a plurality of pages of images, comprising the steps of:

(a) simultaneously displaying respectively index images of the plurality of document files on a display, the index image of each document file being a part or a reduced image of the image of each page of each said document file;

(b) designating one of the index images simultaneously displayed by the display to select the document file corresponding to the designated index image;

(c) inputting a desired page of the selected document file; and

(d) changing the simultaneously displayed index images of the document files to the index images of a predetermined number of pages from the input desired page of the same document file selected.

17. A method according to claim 16, further comprising the steps of:

(a) designating an index image of the index images simultaneously displayed on the display to select an original image of the designated index image; and

(b) changing the simultaneously displayed index images displayed on the selected original image to display the original image.

18. An image retrieval method for retrieving a desired image from a storage medium which stores a plurality of document files each comprising a plurality of pages of images, comprising the steps of:
