Dialog gets imaging chips from Sarnoff

Dialog Semiconductor has acquired the CMOS imaging business and associated CMOS Active Pixel Sensor patent portfolio from the New Jersey-based Sarnoff Corporation.

Dialog Semiconductor has acquired the CMOS imaging business and associated CMOS Active Pixel Sensor (APS) patent portfolio from the New Jersey-based Sarnoff Corporation, the research and development institute formerly known as RCA Laboratories.

As part of the agreement, a core team from Sarnoff is designated to transfer and implement the technology at Dialog.

The financial terms of the deal were not disclosed.

Sarnoff has an extensive patent portfolio in CMOS imaging. Its CMOS active pixel sensor (APS) design, first used in radiography applications in 1998, is suited to applications in digital cameras, mobile phones and automotive applications.

Sensors using CMOS imaging technology are expected to replace the CCD sensors used in the majority of the current generation of digital still and motion cameras.

According to market research from iSuppli Corp’s market intelligence service, unit volumes of CMOS sensors are projected to grow from 18 million devices worth $367 million in 2001, to 72 million units worth more than $1 billion by 2005. On this basis, CMOS image sensors will represent about 47% of all image sensor devices shipped by 2005, up from 23% in 2001.
