AR0833: 1/3.2-Inch 8 Mp CMOS Digital Image Sensor
Functional Overview
grate incident light. The exposure is controlled by varying the time interval between
reset and readout. Once a row has been read, the data from the columns is sequenced
through an analog signal chain (providing gain), and then through an ADC. The output
from the ADC is a 10-bit value for each pixel in the array. The ADC output passes through
a digital processing signal chain (which provides further data path corrections and
applies digital gain).
The pixel array contains optically active and light-shielded (“dark”) pixels. The dark
pixels are used to provide data for on-chip offset-correction algorithms (“black level”
control).
The sensor contains a set of control and status registers that can be used to control many
aspects of the sensor behavior including the frame size, exposure, and gain setting.
These registers can be accessed through a two-wire serial interface.
The output from the sensor is a Bayer pattern; alternate rows are a sequence of either
green and red pixels or blue and green pixels. The offset and gain stages of the analog
signal chain provide per-color control of the pixel data.
A flash output signal is provided to allow an external xenon or LED light source to
synchronize with the sensor exposure time. Additional I/O signals support the provision
of an external mechanical shutter.
Pixel Array
The sensor core uses a Bayer color pattern, as shown in Figure 2. The even-numbered
rows contain green and red pixels; odd-numbered rows contain blue and green pixels.
Even-numbered columns contain red and green pixels; odd-numbered columns contain
blue and green pixels.
