2.1. Image Array
The image array consists of 352x288 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 is 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
needs further processing (i.e., color interpolation and color correction) in order to approximate the full
visible spectrum.
