Detailed Description

An imager noise model.

This model adds a noise frame to the input frame and applies the analog to digital conversion (A/D). The output is voltage. The noise sources accommodated are:

• Fixed pattern noise
• Shot noise
• Temporal noise
• Dark current
• Global photo response non-uniformity
• Temperature noise
• Stray light
