| 20090078773 | Multiple Configuration Image Scanner - An imaging-based bar code reader that includes an imaging and decoding system. Focusing optics and a sensor array define a field of view. An exemplary system has an image sensor includes multiple configuration registers. With multiple configuration registers a video mode can be implemented where the video consists of a continuous sequence of frames with a fixed sequence a number of configurations. The configurations can vary the frame size, exposure time, gain, etc. Compared to a sensor with only one set of configuration registers, successive frames can be captured with different configurations without synchronization issues or frame lag. | 03-26-2009 |
