Bio: Katsuhisa Ogawa started his professional career at National Semiconductor
as analogue LSI designer after being graduated from Hokkaido Institute of
Technology with B.S. in Electronic Engineering. After he joined Canon, he
was engaged in development of Optical Magnetic Memory, LSI for Laser Beam
Printer and Video Camera, was dispatched to Tohoku University as a
researcher to develop A.I via neural network from chip 1995-1997. He
successfully completed CMOS sensor technologies after he returned to Canon
and joined the development team of next generation Internet Protocol(IPv6)
and image processing technology. Now his main focus is in the area of
project planning and development of applied technologies of CMOS sensor to
industrial field.

Abstract: Along with the recent progress of semiconductor technology, Image Sensor
technology has shown a significant improvement so that now we can get high
performance Image Sensors made of silicon chip. In consumer market, the
image sensors become components of digital camera and mobile phone camera
and opend the era of multimedia. In industrial market including medical
field, they indicated further potential by transforming themselves to
surveillance cameras, industrial inspection equipments and diagnostic
imaging equipments.

Initially, CCDs were the main stream of image sensor, but now CMOS sensors
produced by CMOS process are taking the center stage. CMOS sensors are
superior to CCDs in its on chip peripheral circuit and low power
consumption. Well-known S/N problem has been solved with new technologies
such as Noise Reduction Technology and sensitivity improvement.

I will address the technological advancement of CMOS sensors citing
Canon’s example and propose future outlook of CMOS applied technologies.
