Abstract

A display system includes an image forming apparatus for storing screen data and a portable information terminal for displaying a screen based on the screen data stored by the image forming apparatus. The display system accepts flick operation for requesting movement of a screen at the portable communication terminal and transmits flick information concerning the flick operation to the image forming apparatus. The display system successively transmits screen data of screens from the start of movement to completion of movement from the image forming apparatus to the portable communication terminal, based on the flick information. The display system displays a screen based on the transmitted screen data on the portable communication terminal.

7. The display system according to claim 5, wherein said screen data creation unit creates screen data in which a resolution of a screen gradually increases with screen movement.

8. The display system according to claim 5, wherein said screen data creation unit creates screen data in which a screen having a relatively high resolution appears at regular intervals among screens having a relatively low resolution.

9. The display system according to claim 5, wherein said screen data creation unit creates screen data in which the resolution of each successive screen to be transmitted varies in accordance with a sinusoidal wave pattern.

10. The display system according to claim 5, wherein said screen data creation unit creates screen data in which a resolution in a region of a touch position on said second display device in said flick operation is higher than a resolution around a periphery of the touch position on said second display device in said flick operation.

11. The display system according to claim 5, wherein said screen data creation unit creates screen data in which a resolution at an end portion of a screen is lower than a resolution at a central position of the screen.

12. The display system according to claim 5, wherein if screens from start of movement to before completion of movement include an image, said screen data creation unit creates screen data in which the image is grayed out.

13. The display system according to claim 5, wherein if screens from start of movement to before completion of movement include an image, said screen data creation unit creates screen data in which a resolution of the image is lower than a resolution of a region excluding the image.

14. The display system according to claim 5, wherein if screens from start of movement to before completion of movement include major information, said screen data creation unit creates screen data in which a resolution of the major information is higher than a resolution of a region excluding the major information,

wherein the screen data stored by the first display device registers some information as the major information.

15. A display system including a first display device for storing screen data and a second display device for displaying a screen based on the screen data stored by said first display device, comprising:
