Claim One:
1. A method of determining a representative image (RI) for at least one shot (SH) in a video (VD), a shot being a continuous sequence of images representing a scene viewed from a particular location, the method comprising: a shot sampling step (SHS) of selecting images from a shot so as to obtain a continuous sequence of selected images (SI) that are distributed throughout the shot on a time grid that exhibits slight irregularities, not precisely equidistantly spaced; a stable shot portion identification step (SPI) of identifying at least one continuous subsequence (SB) of selected images within the obtained continuous sequence of selected images that meet a predefined similarity test; and a representative image designation step (RID) of selecting an image from a continuous portion (SP) of the shot that coincides in time with a longest continuous subsequence of selected images of the identified at least one continuous subsequence of selected images that meet the predefined similarity test, wherein the image that is selected constitutes a representative image (RI) for the shot.
