Abstract:
1. An apparatus for detecting a scene change comprising; a first accumulated histogram extracting part for receiving a first frame and extracting an accumulated histogram to the first frame; a first pixel list extracting part for extracting a pixel list corresponding to at least one specific accumulated distribution value from the first accumulated histogram extracting part; a second accumulated histogram extracting part for receiving a second frame adjacent to the first frame and extracting an accumulated histogram of the second frame; a second pixel list extracting part for extracting a pixel list corresponding to at least one specific accumulated distribution value from the second accumulated histogram extracting part; a histogram comparing part for measuring a frame difference by comparing outputs of the first and second pixel list extracting parts; and a scene change determining part for comparing the frame difference measured by the histogram comparing part with a preset threshold value, thereby determining whether the scene change occurs.
