ICM105B VGA CMOS sensor
Data Sheet V1.6, August 2002
2. Functional Description
ICM-105B is a single-chip digital color imaging device. It includes a 640x480 sensor array, 640 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
8-bit raw data, together with horizontal and vertical sync signals.

2.1 Image Array
The image array consists of 640x480 pixels. Each pixel has a light sensitive photo diode and a set of
control and transfer transistors. At the beginning of the cycle, a row of pixels are pre-charged to its
maximum value. Then they are exposed to light for several lines worth of time and sampled by the ADC.
Correlated double sampling (CDS) is performed by 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 255.
2.2 Color Filter
Each pixel is covered by a color filter. They form the Bayer Pattern as shown in Figure 2. (Row 0,
Column 0) is covered by a Red filter, (Row 0, Column 1) and (Row 1, Column 0) by Green filters, and
(Row 1, Column 1) by a Blue filter. Since each pixel only gets part of the frequency band, the data need
further processing (i.e., color interpolation and color correction) in order to approximate the full visible
spectrum.
