Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

Abstract: A method for blurred image judgment is provided. Firstly, a focus value FV1 of an original image is calculated. By using a blur function, the original image is obfuscated to generate a blurred image, and then the focus value FV2 of the blurred image is calculated. A blur ratio FV1/FV2 is compared with a blur threshold value Tp, thereby discriminating whether the original image is blurred according to the comparing result. The method for blurred image judgment is applicable to a digital image capture device. If the original image is deemed blurred, a blur image signal is issued to notify the user whether the retaking operation is done.

Abstract: A zoom tracking method for digital camera is disclosed. The method comprises storing a position table comprising data of several zoom position curves respect to positions of a focus lens and move the focus lens position by looking up said position table while moving a zoom lens position. The curves are divided into a first linear region, a second linear region and a nonlinear region to reduce the table size while still achieving good image quality.

Abstract: A wireless cursor control device for use with a computer system includes a main body, a wireless signal receiver, a storing portion and a resilient pad member. The main body generates a wireless signal to control a cursor of the computer system. The wireless signal receiver is swappable to be electrically connected to the computer system for receiving the wireless signal. The storing portion is disposed in the main body for accommodating the wireless signal receiver. The resilient pad member is engaged with the bilateral sides of the storing portion, and deformed to generate a restoring force when the wireless signal receiver is inserted into the storing portion. The resilient pad member is sustained against the wireless signal receiver according to the restoring force.

Abstract: A digital video image stabilization method features scene change detection, adaptive stabilization in two dimensions, prevention of accumulated-compensation saturation, multi-resolution motion estimation, and compatibility with MPEG video encoding standards. The method uses block-based motion estimation on a selected set of macroblocks, which generates and validates a set of motion vectors, to determine how a digital camcorder or other video recording device is moving; accumulates motion data to estimate and preserve overall motion due to panning while eliminating small variations due to shaking; and resets its accumulated motion data when it detects a scene change. The method uses this information to select a sub-image from a larger image for the selected video frame. When one or more edges of the sub-image approach the edges of the larger image, the method reduces its correction factor to transition smoothly to a faster pan and prevent saturation.
