    摘要: A touch sensing method for detecting positions of touching is disclosed. In the present invention, a reference touch profile is provided. A variable ideal combination profile indicating multiple touches is obtained by synthesizing a plurality of reference touch profiles at different positions. The variable ideal combination profile is matched with a sensing signal. Actual touch positions can be identified from the sensing signal when the matching of the variable ideal combination profile with the sensing signal is optimal.

    摘要: A dynamic filtering device includes a variation detector, a coefficient generator and a filter. The cut-off frequency of the filter is dynamically adjusted according to variations of an input signal. A higher signal-to-noise ratio is obtained when a finger moves in slow motion and its response time is reduced when the finger moves in fast motion, therefore improving the response time and the noise immunity of the filter.

    摘要: A hierarchical motion estimation method implemented in a plurality of levels is disclosed. The hierarchical motion estimation method is used for estimating motion vectors of a frame. The frame being partitioned into blocks at a first level, and each block of the first level is partitioned into a plurality of blocks at a second level. The method includes selecting reference blocks at the first level for a specific block at the second level and determining a search range for the specific block at the second level by referring to motion vectors, which are known, of the reference blocks at the first level. By using such a method, the motion vectors of a frame can be rapidly and accurately estimated.

    摘要: A feedback latch circuit includes a first logic OR gate for performing a logic OR operation upon a clock input signal and a latch output, a first logic AND gate for performing a logic AND operation upon output of the first logic OR gate and a data input signal, a second logic AND gate for performing a logic AND operation upon a complementary clock input signal and the latch output, and a second logic OR gate for performing a logic OR operation upon outputs of the first and second logic AND gates to result in the latch output that is provided to the first logic OR gate and the second logic AND gate. The complementary clock input signal received by the second logic AND gate complements the clock input signal received by the first logic OR gate.
