Abstract
An image-capturing device configured for an optical pointing apparatus includes a plurality of image-sensing units arranged adjacently. The plurality of image-sensing units are configured to sense images of a surface and generate sensing signals that are used for evaluating the velocity of the optical pointing apparatus. The image-capturing device is configured to use different image-sensing units arranged differently to sense the surface according to the velocity of the optical pointing apparatus. When the optical pointing apparatus moves at a first velocity, the image-capturing device uses the image-sensing units configured to occupy a smaller area to sense the surface. When the optical pointing apparatus moves at a second velocity, the image-capturing device uses the image-sensing units configured to occupy a larger area to sense the surface. The first velocity is lower than the second velocity.
