Abstract

When a desired field frame is specified on an area of a display in which pages connected in series are displayed in their compressed form, the data in the specified field frame is displayed in a document image display section. When the specified field frame is moved with the use of a previous-page button, a next-page button, a forward-slide button, or a backward-slide button, the data in the moved field frame is displayed in the document image display section. The information concerning the movement of the field frame is transferred to other terminals so that on the white boards of the other terminals, the same processing is performed.

Claims

1. An image processing apparatus comprising:

a display apparatus having an image display area wherein a first image is displayed and a symbol display area wherein a symbol is displayed, the symbol representing part of a whole image and the part corresponding to the first image displayed in said image display area,

a display control apparatus for compressing the whole image to a compressed image that is a smaller version of the whole image and for displaying the part of the compressed image corresponding to the first image as the symbol within said symbol display area,

an instruction apparatus for instructing a change as to which part of the first image is represented by the symbol as a move of the symbol; and

a move control apparatus for controlling the move of the symbol according to the instruction by said instruction apparatus, and for controlling the first image displayed in said image display area in accordance with the move.

2. An apparatus according to claim 1, wherein the symbol is a frame.

3. An apparatus according to claim 2, wherein a width of the frame is wider than a width of said symbol display area.

4. An image processing system having a first image processing apparatus and a second image processing apparatus connected on a network, said first image processing apparatus and said second image processing apparatus each respectively comprising:

a display apparatus having an image display area wherein a first image is displayed and a symbol display area wherein a symbol is displayed, the symbol representing part of a whole image and the part corresponding to the first image displayed in said image display area, p1 a display control apparatus for compressing the whole image to a compressed image that is a smaller version of the whole image and for displaying the part of the compressed image corresponding to the first image as the symbol within said symbol display area,

an instruction apparatus for instructing a change as to which part of the first image is represented by the symbol as a move of the symbol; and

a move control apparatus for controlling the move of the symbol according to the instruction by said instruction apparatus, and for controlling the first image displayed in said image display area in accordance with the move.

5. A system according to claim 4, wherein the symbol is a frame.

6. A system according to claim 5, wherein a width of the frame is wider than a width of said symbol display area.

7. A system according to claim 4, wherein the first image displayed in said image display area of said first image processing apparatus is controlled in accordance with the move instructed by said instruction means of said second image processing apparatus.

8. A method of controlling an image processing apparatus that includes a display apparatus having an image display area wherein a first image is displayed and a symbol display area wherein a symbol is displayed, the symbol representing part of a whole image and the part corresponding to the first image displayed in the image display area, said method comprising the steps of:

a display control step of compressing the whole image to a compressed image that is a smaller version of the whole image and of displaying the part of the compressed image corresponding to the first image as the symbol within the symbol display area,

an instruction step of instructing a change as to which part of the first image is represented by the symbol as a move of the symbol; and

a move control step of controlling the move of the symbol according to the instruction in said instruction step, and for controlling the first image displayed in the image display area in accordance with the move.

9. A method according to claim 8, wherein the symbol is a frame.

10. A method according to claim 9, wherein a width of the frame is wider than a width of the symbol display area.

11. A method of controlling an image processing system having a first image processing apparatus and a second image processing apparatus connected on a network, the first image processing apparatus and the second image processing apparatus each respectively including a display apparatus having an image display area wherein a first image is displayed and a symbol display area wherein a symbol is displayed, the symbol representing part of a whole image and the part corresponding to the first image displayed in the image display area, said method comprising the steps of, in each of the first and second image processing apparatuses:

a display control step of compressing the whole image to a compressed image that is a smaller version of the whole image and of displaying the part of the compressed image corresponding to the first image as the symbol within the symbol display area,

an instruction step of instructing a change as to which part of the first image is represented by the symbol as a move of the symbol; and

a move control step of controlling the move of the symbol according to the instruction in said instruction step, and for controlling the first image displayed in the image display area in accordance with the move.

12. A method according to claim 11, wherein the symbol is a frame.

13. A method according to claim 12, wherein a width of the frame is wider than a width of the symbol display area.

14. A method according to claim 11, wherein the first image displayed in the image display area of the first image processing apparatus is controlled in accordance with the move instructed in said instruction step of the second image processing apparatus.

15. A computer readable storage medium that stores codes for executing a method of controlling an image processing apparatus that includes a display apparatus having an image display area wherein a first image is displayed and a symbol display area wherein a symbol is displayed, the symbol representing part of a whole image and the part corresponding to the first image displayed in the image display area, said method comprising the steps of:

a display control step of compressing the whole image to a compressed image that is a smaller version of the whole image and of displaying the part of the compressed image corresponding to the first image as the symbol within the symbol display area,

an instruction step of instructing a change as to which part of the first image is represented by the symbol as a move of the symbol; and

a move control step of controlling the move of the symbol according to the instruction in said instruction step, and for controlling the first image displayed in the image display area in accordance with the move.

16. A medium according to claim 15, wherein the symbol is a frame.

17. A medium according to claim 16, wherein a width of the frame is wider than a width of the symbol display area.

18. A computer readable storage medium that stores codes for executing a method of controlling an image processing system having a first image processing apparatus and a second image processing apparatus connected on a network, the first image processing apparatus and the second image processing apparatus each respectively including a display apparatus having an image display area wherein a first image is displayed and a symbol display area wherein a symbol is displayed, the symbol representing part of a whole image and the part corresponding to the first image displayed in the image display area, said method comprising the steps of, in each of the first and second image processing apparatuses:

a display control step of compressing the whole image to a compressed image that is a smaller version of the whole image and of displaying the part of the compressed image corresponding to the first image as the symbol within the symbol display area,
