Abstract: Method for detecting disappearance of a pattern is used to detect whether a fixed-still pattern in dynamic displayed images disappears. Method includes analyzing a pattern characteristic parameter which represents the fixed-still pattern from each of images continuously displayed in a time sequence, It is checked whether the pattern characteristic parameter fast decreases from at least greater than a high level to at least less than a low level, as a first state transition. Sum of absolute difference (SAD) values for all of the pixels between a previous image and a current image is calculated. It is checked whether the sum of the SAD values fast increases from at least less than a low level to at least greater than a high level, as a second state transition. When the first state transition and the second state transition occur simultaneously, it is determined that the fixed-still pattern disappears in the display.

Abstract: An frame rate up-conversion (FRC) apparatus and method are provided. The motion vector generating circuit compares a previous original frame with a current original frame to obtain the first motion vectors of the blocks of the current original frame, and compares the current original frame and a posterior original frame to obtain the second motion vectors of the blocks of the current original frame. The motion vector correction circuit checks whether the blocks of the second original frame are located in an occlusion area, and corrects the motion vectors of the blocks in the occlusion area based on the first motion vectors and the second motion vectors of the first original frame, the second original frame and the third original frame. The interpolation frame generating circuit creates at least one interpolation frame between the first original frame and the second original frame based on the corrected motion vectors.
