Canon developed the world’s first Spad sensor with one million pixels. This definition will make it possible to take pictures without noise, measure the distance of objects, and will have applications for cameras, robots, and self-driving cars.
Last year, Canon unveiled the first (Single photon dual vacume Or in French, avalanche binaries in Single) from a megapixel, in collaboration with Swiss researchers. In one And the The company provides more information on this unique breach that could have repercussions in several sectors.
This is new It is usually used in cameras And our smartphones, measure how much in a way , Then converting the result into a digital signal, which creates a lot of “noise”. The Spad works by counting every photon, thus obtaining an image with unparalleled clarity.Primarily designed for use as a monochrome photo and video camera. The
Eyes for robots
To achieve the definition of one million pixels without losing sensitivity, Canon has pushed the limits of current Spad sensors. The company has succeeded in creating square pixels and removing pixel spaces to capture all the light. This technology is extremely fast, and makes it possible to reduce the exposure time to just 3.8 nanoseconds, and thus shoot scenes at a rate of 24,000 frames per second. Hence, Canon was able to create a slow motion clip for the It moves through smoke.
Finally, this sensor can also measure , Such as ToF sensors in smartphones and From’ . This additional information makes it possible to view the scene in three dimensions with much higher accuracy than current sensors. This is used in particular for near-instant autofocus, augmented reality and . Canon places particular emphasis on the use of robots that can be seen in 3D. Curiously, Canon chose to publish more details a year after the initial announcement. Maybe we can hope to see this sensor integrate a car or robot soon?
This ultra-fast camera capable of photographing photons is impressive
Thanks to a collaboration with Canon, EPFL researchers have created a camera capable of capturing 3D images with an extensionAnd an unparalleled definition. MegaX is so fast that it can capture the path of individual photons!

Researchers from (EPFL), in cooperation with Canon, has developed a new type of camera. Thanks to single photon diodes (SPAD), Capable of capturing the path of individual photons with a definition of one million pixels.
MegaX can record up to 24,000 photos per second, and at the same time capture very dark and very bright objects. “We can increase the dynamics dramatically, which is not possible with a high-resolution camera,” the professor noted. .
3D images of multiple objects simultaneously
The device can also measure (ToF) for 3D photos, with a special app in augmented reality. In addition, MegaX can detect multiple objects simultaneously. At the same time, the researchers were able to measure the distance of the ball and the transparent plate placed in front, but it was not visible in a two-dimensional image.The path of the photon between the object and the camera. This means that it acts as a sensor for
At present, MegaX is not intended to replace the image modules in our smartphones. Much larger, each pixel measures 9 Compared to 0.9 μm in a conventional camera. “ My research goal is not necessarily to adapt the MegaX model to a conventional camera, but to create a 4D (3D plus time) camera with as many pixels as possible in order to obtain More important, ‘declared Professor Eduardo .
