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.

摘要： An embodiment of the invention provides a camera comprising a photosurface that is electronically turned on and off to respectively initiate and terminate an exposure period of the camera at a frequency sufficiently high so that the camera can be used to determine distances to a scene that it images without use of an external fast shutter. In an embodiment, the photosurface comprises pixels formed on a substrate and the photosurface is turned on and turned off by controlling voltage to the substrate. In an embodiment, the substrate pixels comprise light sensitive pixels, also referred to as “photopixels”, in which light incident on the photosurface generates photocharge, and storage pixels that are insensitive to light that generates photocharge in the photopixels. In an embodiment, the photosurface is controlled so that the storage pixels accumulate and store photocharge substantially upon its generation during an exposure period of the photosurface.
