Method and system for adjusting depth of view in optical sensor

摘要

Method and system are disclosed for adjusting the depth of view in an optical sensor of a pointing device (see FIG. 4). The method and system of the invention allow a user to select a depth of views from multiple depths of view. The user may select the depth of view using an appropriate graphical user interface. The depth of view may also be selected by the pointing device with no user input. In either case, the depth of view of the optical sensor may be adjusted to more accurately account for different levels of contrast in the micro-texture of the user's work surface.
