「SPAD」（Single Photon Avalanche Diode）：
信号増倍画素構造を持つセンサーにおいて、世界初の100万画素の撮像が可能なイメージセンサーを開発したことを発表した。
SPADイメージセンサー：
- 極めて短い時間内に起こる高速な現象など
- 特殊な静止画・動画を撮影する2次元カメラとしての応用
- 被写体までの距離情報を画像として取得する3次元カメラへに活用される。
自動運転でも車間距離測定などでの活用が見込まれます。
高性能な「目」として注目を集めそうだ。

Canon develops world’s first 1-megapixel SPAD image sensor
TOKYO, June 24, 2020—
Canon Inc.
announced today that the company has developed the world’s first1 single photon avalanche diode (SPAD) image sensor with signal-amplifying pixels capable of capturing 1-megapixel images.
SPAD image sensors
are ideal for such applications as 2-dimensional cameras, which capture and develop still image and video in an extremely short span of time.
These sensors also hold potential for use in 3-dimensional cameras due to their ability to obtain information about the distance between them and a subject as image data.
A SPAD sensor
is a uniquely designed image sensor in which each pixel possesses an electronic element.
When a single light particle, called a photon, reaches a pixel it is multiplied—as if creating an “avalanche”—that results in a single large electrical pulse.
The ability to generate multiple electrons from a single photon provides such advantages as greater sensitivity during image capture and high precision distance measurement.
