IPC: H04N7/26
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To detect a statistic fade in a digital video image like a video frame by comparing a fade index with a fade threshold in order to determine whether or not the fade is to be shown. SOLUTION: The difference between a delay frame and an input video is received by a subtracter 115 and applied to a square function 120. The square of the difference is applied to an accumulator 125, the difference dispatched to one field and squared is accumulated, and En is applied as the sum of squared differences. The output of the subtracter 115 is applied to the accumulator 130, a differential value is accumulated and Dn is applied as the sum of pixel differences. Besides, a dividing function 150 applies a fade index Jn=(En/ N) corresponding to the current field to a field delay function 170 and an adding and dividing function 160. After the fade index is averaged corresponding to both the fields of the frame, it is compared with the experiential threshold value by a detector 165 and when the average is lower than the threshold value, the fade is shown.
