「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:

  1. 極めて短い時間内に起こる高速な現象など
  2. 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
  3. 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.
