digital zoom of a panable viewport. Subsampling
provides reduced resolution while maintaining
constant field of view.
The analog video output of the pixel array is
processed by an on-chip analog signal pipeline.
Correlated Double Sampling (CDS) eliminates the
pixel reset temporal and pattern noise. The Frame
Rate Clamp (FRC) enables real time optical black
level calibration and offset correction. The
programmable analog gain consists of
exposure/global gain to map the signal swing to
the ADC input range, and white balance gain to
perform color balance in the analog domain. The
ASP signal chain consists of (1) Column op-amp
(1.5x fixed gain); (2) Column DOVA(1.5x fixed
gain); (3) White Balance PGA (0.70 Æ 2.74x); (4)
Global PGA (0.48 Æ 7.50x); and (5) Global DOVA
(2.0x fixed gain). These Digitally Programmable
Amplifiers (DPGAs) allow real time color gain
correction for Auto White Balance (AWB) as well
as exposure gain adjustment. Offset calibration
can be done on a per column basis and globally.
This per-column offset correction can be applied
by using stored values in the on chip registers. A
10-bit Redundant Signed Digit (RSD) ADC
converts the analog data to a 10-bit digital word
stream. The fully differential analog signal
processing pipeline serves to improve noise
immunity, signal to noise ratio, and system
dynamic range. The sensor uses an industry
standard two-line I2C-compatible serial interface. It
operates with a single 3.3V power supply with no
additional biases and requires only a single Master
Clock for operation up to 20 MHz. It is housed in a
48 pin ceramic LCC package.
The KAC-1310 is designed taking into
consideration interfacing requirements to standard
video encoders. In addition to the 10 bit Bayer
(RGB or CMY) encoded data stream, the sensor
outputs the valid frame, line, and pixel sync
signals needed for encoding. The sensor
interfaces with a variety of commercially available
video image processors to allow encoding into
various standard video formats. In addition, the 3
sync signals can be integrated into the video data
stream eliminating the need of the 3 sync outputs
The KAC-1310 is an elegant and extremely
flexible single chip solution that simplifies a system
designer’s tasks of image sensing, processing,
digital conversion, and digital signal processing to
a high performance, low cost, low power IC. It
supports a wide range of low-power, portable,
consumer digital imaging applications.
