    摘要: An optical navigation system. The optical navigation system includes an image sensor capable of optical coupling to a surface of an object, a data storage device, and a navigation circuit. The image sensor includes multiple photosensitive elements with the number of photosensitive elements disposed in a first direction greater than the number of photosensitive elements disposed in a second direction. The second direction is perpendicular to the first direction. The image sensor is capable of capturing successive images of areas of the surface, the areas located along an axis parallel to the first direction. The data storage device is capable of storing the captured images. The navigation circuit includes a first digital circuit for determining an estimate for the relative displacement between the image sensor and the object along the axis obtained by comparing the image captured subsequent to the displacement to the image captured previous to the displacement.

    摘要: Power savings occur when the optical path of an optical navigation device is configured to provide that maximum energy from the light source is reflected by the navigation surface to the photosensors of the optical navigation chip. Additional power savings may be achieved when the maximized optical path is combined with the features of a controlled light source that uses specular reflection.

    摘要: An optical navigation system, e.g. optical mouse, determines optical navigation quality by examining some or all of the photosensors of a frame or monitoring intermediate or final results of the motion estimation system. The optical navigation quality is then used to determine the navigation output produced by the optical navigation system.
