Comparable to the human eye, Canon releases the world’s first 1-megapixel SPAD sensor
This article comes from Pacific Computer Network
Recently, Canon released the world’s first 1-megapixel SPAD image sensor. This sensor can complete shooting in a low-light environment at an unprecedented speed and can achieve 24,000 frames per second image capture. It can also detect individual photons, record them at extremely high speeds, and convert them into electrical signals. Through the precise control of the light entering time, the SPAD sensor can achieve high sensitivity and high precision imaging, which is very suitable for capturing ultra-high-speed moving objects or for increasing the dynamic range of photos.
The image sensor built by traditional CMOS technology, each group of pixels must accumulate at least 1,000 groups of photons, in order to form a clear image on the 1 million pixel photosensitive element. In order to enhance the performance of the CMOS sensor under dark light, it is necessary to increase the sensor area and improve the shutter design to allow the sensor to obtain enough photons. However, SPAD technology can effectively improve the collection efficiency of photons, and can also achieve fast and accurate shooting effects in low-light environments, while recording correct image information, and even capturing complete 3D spatial data like the human eye.
In the future, image sensors built through SPAD technology will be more used in scientific research, robotics, autonomous driving, and security monitoring.
