Abstract
An imaging system and method for alleviating perceptional problems of a viewer during the transmission and display of high resolution still images on a video system is disclosed. Through modifications to an encoder and decoder within the imaging system, the viewer may select a still image or portion thereof from a video image sequence for viewing. The imaging system and method ameliorate perceptional delays in displaying the lengthy high resolution still image by immediately displaying a lower-resolution, shorter-length video image frame corresponding to the still image. The lower resolution video image being displayed is then updated and refined with the image data from the high resolution still image as it is received.
