    SINGAPORE, 3 April 2023 — Canon Inc. announced today that the company is developing the MS-500, the world’s first1 ultra-high-sensitivity interchangeable-lens camera (ILC) equipped with a 1.0 inch Single Photon Avalanche Diode (SPAD) sensor2 featuring the world’s highest pixel count of 3.2 megapixels3. The camera leverages the special characteristics of SPAD sensors to achieve superb low-light performance while also utilizing broadcast lenses that feature high performance at telephoto-range focal lengths. Thanks to such advantages, the MS-500 is expected to be ideal for such applications as high-precision monitoring.

    There is a growing need for high-precision monitoring systems for use in such environments as national borders, seaports, airports, train stations, power plants and other key infrastructure facilities, in order to quickly identify targets even under adverse conditions including darkness in which human eyes cannot see, and from long distances.

    The currently in-development MS-500 is equipped with a 1.0 inch SPAD sensor that reduces noise, thus making possible clear, full-colour HD imaging even in extreme low-light environments. When paired with Canon’s extensive range of broadcast lenses, which excel at super-telephoto image capture, the camera is capable of accurately capturing subjects with precision in extreme low-light environments, even from great distances. For example, the camera may be used for nighttime monitoring of seaports, thanks to its ability to spot vessels that are several km away, thus enabling identification and high-precision monitoring of vessels in or around the seaport.

    With CMOS sensors, which are commonly used in conventional modern digital cameras, each pixel measures the amount of light that reaches the pixel within a given time. However, the readout of the accumulated electronic charge contains electronic noise, which diminishes image quality, due to the process by which accumulated light is measured. This leads to degradation of the resulting image, particularly when used in low-light environments. SPAD sensors, meanwhile, employ a technology known as “photon counting”, in which light particles (photons) that enter each individual pixel are counted. When even a single photon enters a pixel, it is instantly amplified approximately 1 million times and output as an electrical signal. Every single one of these photons can be digitally counted, thus making possible zero-noise during signal readout—a key advantage of SPAD sensors4. Because of this technological advantage, the MS-500 is able to operate even under nighttime environments with no ambient starlight5, and is also capable of accurately detecting subjects with minimal illumination and capture clear colour images.

    The MS-500 employs the bayonet lens mount (based on BTA S-1005B standards) which is widely used in the broadcast lens industry. This enables the camera to be used with Canon’s extensive range of broadcast lenses which feature superb optical performance. As a result, the camera is able to recognize and capture subjects that are several km away.

    Going forward, Canon will continue to pursue R&D and create products that could surpass the ability of the human eye and that contributes to the safety and security of society based on its long history of comprehensive imaging — optical, sensor, image processing and image analysis — technologies.

    Canon plans to begin selling the MS-500 in 2023.
