    摘要： A system and method are disclosed for selectively focusing on certain areas of interest within an imaged scene to gain more image detail within those areas. In general, the present system identifies areas of interest from received image data, which may for example be detected areas of movement within the scene. The system then focuses on those areas by providing more detail in the area of interest. This may be accomplished by a number of methods, including zooming in on the image, increasing pixel density of the image and increasing the amount of light incident on the object in the image.

    摘要： A depth-mapping method comprises exposing first and second detectors oriented along different optical axes to light dispersed from a scene, and furnishing an output responsive to a depth coordinate of a locus of the scene. The output increases with an increasing first amount of light received by the first detector during a first period, and decreases with an increasing second amount of light received by the second detector during a second period different than the first.
