摘要： A method to detect the movement of an image sensor. Movement is detected according to a first, second, third, and fourth frame, all captured by the image sensor. A first captured image region is captured from the first frame. Then, a first corresponding region matching the first captured image region is captured from the second frame, wherein the first corresponding region shifts in a predetermined direction relative to the first captured image region. Next, a second captured image region is captured from the third frame, wherein the second captured image region shifts in a direction opposite to the predetermined direction relative to the first captured image region. Then, a second corresponding region matching the second captured image region is captured from the fourth frame. Finally, the movement of the image sensor is determined according to the second captured image region and the second corresponding region.

摘要： A method of estimating image displacement by block matching for a pointing device used in a computer system. The method provided in the present invention comprises capturing digital images sequentially using a photo capture device, obtaining a template frame and a current frame, estimating a predicted velocity vector, and computing the displacement of the image. The efficiency and reliability of block match searching are improved by reducing the search range according to the calculated displacement. The template block can be defined anywhere on the template frame according to the predicted velocity to extend the lifetime of the template frame, and the displacement vector between the template block and the center of the template frame is proportional to the predicted velocity.

摘要： A method and device of feature enhancement for digital image processing. A predefined feature in one dimension of the image is searched to obtain several peaks, and each peak is either a local maximum or local minimum. Each peak is enhanced by adding an offset to increase the local maximum or decrease the local minimum. The offset of each peak is computed by calculating the difference between each peak and the preceding peak, then multiplying by a preset ratio.

摘要： An optical mouse and image capture chip thereof. The image capture chip comprises an image sensor, a calculating logic circuit, and a refreshing logic circuit. The image sensor has a plurality of sensor units, capturing an image according to an exposure parameter to provide a plurality of exposure values. The calculating logic circuit provides an average exposure value by calculating the exposure values. If the exposure sample is within a first exposure range, the refreshing logic circuit maintains the exposure parameter and accordingly drives the image sensor to capture a next image. If the average exposure value is within a second exposure range, the refreshing logic circuit adjusts the exposure parameter with a first exposure extreme and accordingly drives the image sensor to capture a next image. If the average exposure value is within a third exposure range, the refreshing logic circuit adjusts the exposure parameter with a second exposure extreme and accordingly drives the image sensor to capture a next image.
