1.19.1.4.5.3 Gray scale version
1.19.1.4.6 CCD Signal Processing
The CCD signal is processed with an analog front-end and digitized by an 12 bit analog-to-digital converter
(ADC). The analog front-end contains a programmable gain amplifier which is variable from 0db (gain=0) to 30dB
(gain=255).
The 8 most significant bits of the ADC are captured to the frame buffer. This will give the following transfer function
(based on the 8 bit digital code): Digital_code [lsb] = ccd_signal[V] ∗ 256[lsb/V] ∗ exp(gain[bB]/20) lsb : least
significant bit (smallest digital code change)
