Abstract: A vehicle modular side view mirror assembly is disclosed. The mirror base has a first section capable of attachment to a vehicle and a second section capable of attachment to a mirror head, wherein the second section is movable relative to the first section. The mirror assembly can include a mirror head having a reflective surface and a motor for moving the mirror head relative to a mirror base, the mirror head detachably connectable to the mirror base. Lidar sensors can be mounted in addition to, or in place of, the side view mirrors. Interchangeable modular heads can allow a user to customize the vehicle to have mirror heads, sensors, both, or neither. Mirror bases can move, allowing the mirrors and/or sensors to be positioned at different angles. In some configurations, the position of the sensors can be dynamically adjusted according to the speed and/or direction of the vehicle.

Abstract: 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.

Abstract: 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.

Abstract: An image processing apparatus includes a first register, a second register and an adder. The second register reads a number of pixels from a sub-window image in turn. 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.
