Abstract
A method of and apparatus for displaying an image clip comprising a plurality of image frames on an electronic monitor includes separating each image frame from the next image frame by an overscan period. In this way image frames captured at a first frame rate can be displayed at the first frame rate on a monitor arranged normally to display images at a second frame rate, different to the first frame rate. In practice, the overscan period is created by adjusting driving circuitry for the monitor to increase the number of lines of data output to the monitor during a frame or field period whilst maintaining the line rate constant.
