Interactive image display.

摘要

A method of interactively controlling the display of an image on a monitor screen (10), the image being stored in the form of digital data defining the colour content of pixels of the image. The method comprises: i) displaying a representation of the image on the monitor screen (10); ii) selecting a first point (12 min ) on the image and a first point (12 sec ) on the monitor screen at which the first image point is to be located; iii) selecting with a cursor a second point (14) on the image; iv) moving the cursor relative to the monitor screen; v) and during the cursor movement repeatedly adjusting the representation of the image displayed in accordance with one or more predetermined algorithms so that the second image point remains coincident with the cursor position while the first image point is fixed at the first screen point. o
