"The sensor can recognize light at one-tenth the brightness conventional sensors need, lending itself to a range of industrial applications such as driving and surveillance.
The number of pixels in a sensor is key to image clarity, and Canon's SPAD sensor boasts 3.2 million, making it the world's densest, more than three times the number of the company's conventional sensor. It can recognize the time of light returning in units of less than a nanosecond, allowing for more accurate object recognition.
Canon's factory in Kawasaki will begin mass-producing the new sensor in the second half of 2022. The company plans to install the sensors in its own security cameras that it is to introduce by the end of next year. It will also market the sensors to other companies.
In 2023, Canon will invest more than 21 billion yen ($185 million) to build a new image sensor plant in the Kanagawa Prefecture city of Hiratsuka, where it plans to gradually increase production of the sensor. The sensor can be made with the production technology used for CMOS sensors and at around the same cost."
