Charge integration
Charges to voltage
Amplification of voltage
Analog output
Processing PLD
Programming logic Device
Embedded with processing algorithm
Micro processor has a bi-directional path
Inputs
Raw pixel data
Timing and Control Signals
Static Grey Scale Thresholding
Upper and Lower bound are established
Data of interest and non-interesting data
“Data of interest” are transmitted out of camera
Non-Interesting data are not transmitted.
Boundary values are in Grey Scale (0-255)
