Fujinon Optical Image Stabilisation provides instant results without losing any frames

Even small vibrations of the mounting point of zoom lenses can lead to very shaky and often unusable video capture. To be on the save side, high-performance image stabilisation is key to compensate for such vibrations. Camera vibrations Vibrations influencing a camera and zoom-lens installation may derive from heavy engines in a building, ship or other vehicles. They can also be induced by bypassing railway trains or strong, low-frequency sound sources in factory environments or even just strong winds. Software based stabilisation might sound like a good hands-on solution. However, Optical Image Stabilization from FUJINON has multiple advantages over electronic/software based approaches: Higher picture quality without frame lossThis is especially true with regards to the observation of moving objects. While software based stabilisation requires several frames to calculate a stabilised image, optical stabilisation provides instant results without losing any frames. Maximum field of view and constant image section Electronic stabilisers require cropping numerous pixels at the edges of the video image while optical stabilisation continuously shows the full frame without losing image sensor resolution or field of view. Compensation of up to 4x stronger vibration The Optical Image Stabilization in FUJINON's zoom devices is capable to deliver steady video captures even at vibrations which are up to four times stronger than software-based stabilisers can compensate for, depending on frequency and amplitude of the vibration. This video demonstrates the significant value-add of Optical Image Stabilization (OIS) in the FUJINON D60x16.7 zoom lens. Designers of demanding surveillance systems, where cameras and lenses might possibly be exposed to vibrations, should get it right from the beginning and compare the capabilities of optical vs. electronic image stabilisation by evaluating Fujinon's D60x16.7 zoom lens with 60x zoom, 2 megapixel resolution for up to 1/1.8” image sensors and C-mount.

Fujinon Zoom Lenses at Security 2018
Fujinon Zoom Lenses at Security 2018

This years´ booth of FUJIFILM at Security Essen focusses on the great variety of high quality zoom lenses. The highlight on the booth is the expanded line-up of the Full HD Fujinon zoom lens series with 32x and 60x optical magnification that will be presented in live demonstrations. The well-known 60x Tele-zoom lens series D60x16.7 features 2 Megapixel/Full HD resolution and covers a focal length range of f = 16.7 ~ 1000 mm on 1/1.8” security cameras. These high-end Tele-zoom lenses offer optical image stabilization, autofocus function, a visible light cut filter (“fog-filter), ND filters, a built-in 2x extender and many features more for highest image quality. Analog control is provided as well as a serial interface to control the lens via PC. As an addition, the new HD60x16.7 lenses are introduced to the market at Security Essen. They offer the same optical and mechanical specification as incorporated in the high-end D60x16.7 series, but with analog control only and reduction of the 2x extender and ND filters for best price-performance ratio – without compromising image quality. The 32x zoom lenses impress with Full HD image quality across the entire zoom range with maximum focal lengths of up to f = 400 mm (FD32x12.5SR4A) and f = 500mm (FH32x15.6SR4A). To respond to increasing market demands for color images even in low light, the lenses are designed for large sensor sizes of 1/1.8” and 2/3”. The built-in visible-light-cut filter enables reliable performance even in fog, rain and snow. Since the lenses have a small size and offer analog control as well as serial control, the lenses are very easy to integrate into housings and into existing surveillance systems.
