    摘要: A digital image stabilization method that integrates a digital stabilization device and a digital video encoder is disclosed. The digital stabilization device comprises a determining module for determining background regions, a comparison module for calculating motion vectors, and an adjustment module for adjusting jerky image motion in frames. When there are frame jiggles, the motion vector between an I frame and a P frame is used for motion estimation to get a first motion vector and also define a background region of the P frame. Next, a second motion vector of a B frame is calculated according to the background region to adjust jerky motion of the P frame and the B frame for stabilization. The next P frame then uses the background region of the preceding P frame as its background region.

    摘要: A method and an apparatus thereof for enhancing a digital image. The method includes the steps of: capturing a pixel data block; determining a searching region and a reference window with the pixel data block serving as a center; dividing the searching region into compared windows each having a size equal to a size of the reference window; sequentially comparing the compared windows to the reference window to determine corresponding weighting values according to compared results; multiplying calculated blocks in the compared windows by the corresponding weighting values of the blocks to obtain weighted blocks; accumulating the weighted blocks to obtain a summed pixel data block; accumulating the weighting values to obtain a summed weighting value; and normalizing the summed pixel data block according to the summed weighting value to obtain an image-enhanced pixel data block.

The adder adds the pixels in the second register and stored values in the first register to output a number of adding calculation values. The adding calculation values are returned to the first register and are saved as stored values. In addition, the present invention relates to an image processing method and a human face detection system using the above image processing apparatus.

    摘要: Methods are proposed for object positioning for an X-Y projected capacitive touch panel. In an embodiment, capacitance sensing under inphase excitation of traces is applied to set a base value when the capacitive touch panel is not touched and to obtain capacitances at intersections when the capacitive touch panel is touched, and the base value is compared with the measured capacitances to identify touch points. In other embodiments, X-Y projected sensing and all-point sensing are combined to reduce the amount of calculation and achieve the same positioning effect as an all-point capacitive touch panel.
