ICM107B Mega pixel CMOS sensor
Data sheet Version 0.5, January 2002
2. Functional Description
ICM-107B is a single-chip digital color imaging device. It includes a 1152x864 sensor array, 1152
column-level ADC, and correlated double sampling circuitry. All the programmable parameters are set by
writing into the SIF interface which can address the register file consisting of 8-bit registers. The output
format is 10-bit raw data, together with horizontal and vertical sync signals.

2.1 Image Array
The image array consists of 1152x864 pixels. Each pixel has a light sensitive photo diode and a set of
control transistors. At the beginning of the cycle, a row of pixels is pre-charged to its maximum value.
Then the row is exposed to light for several lines worth of time and sampled by the ADC. A “Correlated
Double Sampling (CDS)” process is performed with subtracting the reset value (sampled right before
sampling the signal) from the signal value. The purpose of CDS is to eliminate the point-wise fixed pattern
noise (FPN). The output of CDS is approximately proportional to the amount of received light, ranging
from 0 to 1023.
