1. An imaging device for capturing optical image data, the device comprising:

  • an imager for generating an image signal;

    a memory component that receives the image signal from the imager and stores the image signal as image data; and

    a processor that executes an exposure control routine by implementing a first module that controls the exposure and gain setting in the imager and a second module that implements computations in response to image data transmitted from the memory component and exposure data transmitted from the first module to determine a targeted exposure and gain setting.
