Title: 40-5 | Cross Dual-Pixel Twisted-Photodiode Image Sensor for All-Directional Auto Focus

Description: Authors:
Daiki Shirahige, Canon Inc., Koichi Fukuda, Canon Inc., Hajime Ikeda, Canon Inc., Yusuke Onuki, Canon Inc., Ginjiro Toyoguchi, Canon Inc., Hiroshi Sekine, Canon Inc., Shuhei Hayashi, Canon Inc., Kohei Okamoto, Canon Inc., Shunichi Wakashima, Canon Inc., Ryo Yoshida, Canon Inc., Junji Iwata, Canon Inc., Yasushi Matsuno, Canon Inc., Katsuhito Sakurai, Canon Inc., Hiroshi Yuzurihara, Canon Inc., Takeshi Ichikawa, Canon Inc.

We present a newly developed CMOS image sensor with high AF performance based on a twisted PD structure, in which the photodiode is twisted by 90 degrees. The proposed structure realizes PDAF at all pixels and in all directions, and the minimum AF illuminance level of 0.007 lux is achieved.
