1. A method of detecting a shot transition of a moving picture video, comprising the steps of:
- obtaining color histogram differences between three frames placed at different points of time on time series; and
detecting the shot transition by using arrangement characteristics of the color histogram differences concurrently.

Abstract
Disclosed herein is a method of detecting a shot transition of a moving picture video, comprising the steps of: extracting a color histogram of three adjacent frames in order on time series; obtaining a difference of the color histogram between the three adjacent frames and then detecting a shot transition candidate interval by concurrently using arrangement characteristics of the difference of the color histogram; and examining a distribution of a macro block type within the shot transition candidate interval and verifying whether a shot transition is present or not within the shot transition candidate interval.

17. A method of detecting a shot transition of a moving picture video, comprising the steps of:
-
extracting a color histogram of three adjacent I frames in order on time series;
obtaining a difference of a pair of the color histogram combined from the three adjacent I frames;
detecting a shot transition candidate interval by concurrently using arrangement characteristics of the difference of the color histogram; and
examining a distribution of a macro block type within the shot transition candidate interval, verifying whether a shot transition is present or not within the shot transition candidate interval, and if it is verified that the transition is present, identifying the shot transition candidate interval as a separate shot.
