Long range colour images at night

October 2015 CCTV, Surveillance & Remote Monitoring, Products

Canon is developing a high-sensitivity network camera equipped with a fast high-magnification lens capable of long-range colour image capture even at night, making possible the viewing of subjects that the naked eye would have trouble discerning.

Amid ever-increasing safety and security concerns, a growing need for advances in surveillance systems has fuelled demand for high-performance network cameras capable of clearly recording visual data night and day for such applications as urban surveillance and the monitoring of important infrastructure facilities.

Canon is developing a compact high-sensitivity network camera that will make possible the clear viewing in colour of distant subjects even under conditions that would prove challenging to the naked eye, such as at night with few ambient light sources. The camera’s imaging capabilities will make it ideally suited for such surveillance applications as crime prevention and the monitoring of natural disaster sites, enabling the viewing of scenes during either night or day.

Drawing on a range of optical technologies Canon has cultivated over many years, the network camera being developed will feature a large-aperture ultra-telephoto zoom lens with a focal length of more than 600 mm (35 mm film equivalent) that achieves a bright F-value of 2.4 to allow large amounts of light to enter. The lens will incorporate aspherical and UD (Ultra Low Dispersion) lens elements that suppress the incidence of chromatic aberrations, which become more prevalent as a lens’s aperture size increases, while making possible a compact lens unit.

The combination of the large-aperture lens with a high-sensitivity sensor and high-performance image processor will enable the colour recognition of a subject’s face at a distance of 100 metres even in dark environments with a mere 0.08 lux of illumination, roughly equivalent to the illuminance of moonlight. By comparison, conventional night-time surveillance to date has only been possible within a limited range with the aid of infrared illumination, or by using a night mode that only captures images in black and white.

Through the combination of an electric-drive pan/tilt function that controls the camera’s orientation with the ultra-telephoto zoom lens, the network camera will be able to fulfil a wide range of surveillance requirements. Canon aims to commercialise the new network camera in 2016.
