AMBARELLA HYBRID CAMERA PLATFORM INCORPORATES APTINA TEN MEGA-PIXEL SENSOR FOR HIGH RESOLUTION PHOTOS AND VIDEO

Photographers can snap high-resolution still images, high-definition video,
or both on the fly.

SANTA CLARA, CA – January 8, 2009 — Ambarella, Inc., the leader in
low-power, high- definition video compression and image processing
semiconductors, has incorporated the 10 Mega-pixel (MP) sensor from Aptina
Imaging, a global provider of CMOS imaging solutions, into its newly
announced A5 hybrid camera platform.

The Ambarella A5, announced earlier this week, combines a high-performance
image pipeline with an H.264 compression engine. The Aptina 10 MP sensor is
a CMOS device capable of acquiring as many as 2 million pixels at a
sustained input rate of 60 frames per second (fps). By integrating the
Aptina 10 MP sensor into the Ambarella platform, photographers and
videographers can purchase a hybrid camera that fits into a shirt pocket
yet still shoots high-quality digital still images and full high-definition
video separately or in combination.

Aptina’s rapidly advancing CMOS technology enables high-performance cameras
as seen in the MT9J001 10MP image sensor. The sensor incorporates a unique
1.67-micron pixel format and the HiSPi serial data interface to achieve
full HD (1080p60) video performance, beyond the capabilities of CCD
technology.

In utilizing the Aptina part as the sensor input component to the Ambarella
platform, the companies addressed the challenge of delivering high-quality
pictures captured in low light conditions. High sensitivity and advanced
motion compensated temporal filtering are combined to allow sharp,
noise-free video and still images even in a low light environment. A
high-speed serial interface co-developed by Ambarella and Aptina (HiSPi)
enables high frame rate data transfer between the semiconductor chips.

“Working with Aptina to enable compact high-definition hybrid cameras
changes the way consumers can capture, share and store memories,” stated
Dr. Didier LeGall, executive vice-president of Ambarella. “Both Ambarella
and Aptina have proven records of developing cost-effective and
cutting-edge technology that enables highly unique and desirable consumer
products.”

“The 10MP MT9J001 image sensor’s unique HiSPi interface and high speed
frame rate are an excellent match with Ambarella’s new high-performance A5
hybrid camera platform,” noted Sandor Barna, vice-president and general
manager for camera sensors at Aptina. “The solution created by these
combined technologies addresses the desire consumers have for capturing
high-speed video without sacrificing the image quality of a conventional
digital still camera.”

Pricing and Availability
The Ambarella A5 with Aptina 10 MP reference kit is available now for
evaluation or development. Pricing information can be obtained directly
from Ambarella at www.ambarella.com or by calling 1-408-734-8888. The
MT9J001 is currently sampling with mass production in limited quantities
starting in Q1, 2009.
