  • Graphical user interface based control of imaging parameters including scene illumination parameters
    Patent number: 7679602
    Abstract: Systems and methods that provide graphical user interface based control of imaging parameters, including scene illumination parameters, are described. In one aspect, optical data is generated in response to light received from a field of view. Output light is produced. The output light is projected toward the field of view. At least a portion of the optical data is processed into image data that is presentable on a display. A brightness control interface that receives user input specifying a brightness level is generated on the display. An illumination control signal is produced in response to user input specifying a brightness level to the brightness control interface. The illumination control signal configures the output light to be produced with a brightness level corresponding to the brightness level specified to the brightness control interface.
