Other problems that need to be accounted for

• Frame grabbing problems

• • Mapping of CCD array to actual grabbed image

    • Example: Sony XC-75 has a CCD of 752(H) by 582(V) pixels which have dimensions of 8.4µm(H) by 9.8µm(V) while the frame grab is 640 by 480 with has a square pixel display.

Center pixel determination
• CCDs aren’t mounted centered around the optic center (get real term here).
  • No real incentive for commercial manufacturers
  • Prof. Tomasi has seen some off by 10-15 pixels
