ON Semiconductor Demonstrates Low-Light Enabled Fast Auto Focus Technology

Innovative CMOS image sensor pixel technology
accelerates auto focus performance in smartphone applications while
operating in challenging low-light conditions.
ON Semiconductor (Nasdaq: ONNN), driving energy efficient
innovations, has successfully demonstrated its second generation
Phase Detect Auto Focus (PDAF) technology featuring a unique pixel
micro-lens technology that enables fast focus at 25 Lux light
levels. This unique technology has been successfully implemented on
a 13 megapixel (MP) test chip with 1.1 micron (µm) pixels and will
be utilized in a new product introduction for mobile end-market
customers later this year.
Traditional smartphone autofocus (AF) algorithms use a contrast
detection measurement and multiple frames to adjust the lens focus.
This trial-and-error method can take over 1.2 seconds to find focus
in an image. ON Semiconductor’s PDAF technology uses two pixels to
measure phase information from the target image. This phase
information is then used to calculate the direction and the amount
the lens needs to move to focus in less than 0.3 seconds, depending
on focus actuator speed. Furthermore, ON Semiconductor has
implemented a unique pixel micro-lens structure which maintains
sensitivity in the PDAF pixels and ensures enough light is captured
for PDAF to perform in low-light conditions as low as 25 Lux
(similar to a dimly lit room). Competing technologies on the market
employ methods that compromise pixel sensitivity and low light auto
focus performance.
“ON Semiconductor’s PDAF technology is the result of innovations
in both pixel and optical stack design,” said Shung Chieh, vice
president, Mobile and Consumer Division for ON Semiconductor. “The
outcome is a reduction of auto focus time by nearly a factor of
four and delivers a great experience to the mobile device user. The
leading low-light capability of our technology enables smartphone
manufacturers to deliver a fast AF experience across all light
levels to their customers.”
ON Semiconductor will be demonstrating its latest image sensor
technology and products at Mobile World Congress (MWC) 2015 in
Barcelona, Spain, from March 2-5. To schedule a private tour of the
company’s live image sensor demonstrations please contact your ON
Semiconductor sales representative.
