Contents ▪ Who is SVS-Vistek? ▪ Current situation of lens control ▪ Lens control from CCTV market ▪ New lens control options ▪ Applications ▪ Q & A

Who is SVS-Vistek? ▪ Camera Manufacturer ▪ 60 employees ▪ VGA up to 120MP ▪ (Dual) GigE Vision, USB3 Vision, Camera Link, CoaxPress ▪ Customizations, OEM solutions ▪ Sebastian Bachmann ▪ Manager OEM and Application Engineering

Current situation of Lens control ▪ Physical Adjustment needed ▪ Change lens settings ▪ Move camera ▪ Multiple camera systems ▪ => expensive, complexe, inaccurate ▪ Fixed-Iris ▪ Manual-Iris

Fixed Iris ▪ No iris control ▪ Often small M12 lenses ▪ Brightness control over exposure time or gain ▪ Focus controlled by screw-in depth ▪ No possibility to fix the focus

Manual Iris ▪ Aperture control manual ▪ Focus control manual ▪ Often fixed focal length ▪ Physical adjustment needed ▪ Often one time adjustment during installation

Lens control options from CCTV ▪ Auto-Iris ▪ P-Iris

CCTV market - Auto Iris ▪ Motorized control of iris ▪ DC-Iris: Control of iris is in the camera ▪ Video-Iris: Control of iris in the lens ▪ Depending on lightning conditions the iris can be opened and closed ▪ Control cable needed Computar.com

CCTV market - P-Iris ▪ P-Iris – Precision Iris ▪ Exact controlling of the aperture ▪ Set aperture to an exact value ▪ Control cable needed Computar.com

New Lens control options ▪ Liquid lens – up to 2/3“ ▪ Micro-Four-Third lens – up to 4/3“ ▪ Canon lens – larger sensors

What is a Liquid Lens? ▪ Electronically controllable variable focus ▪ Water / oil ▪ Focus is very fast ▪ No zoom ▪ No aperture control Corning Incorporated

Liquid Lens ▪ Fixed Iris ▪ Focus control with Software ▪ Cable for controlling needed ▪ GeniCam Implementation

What is a Micro-Four-Third Lens? ▪ Coming from DSLR cameras ▪ Manufacturers: Panasonic, Olympus, Sigma, etc. ▪ Lenses in different price ranges ▪ Direct communication with camera ▪ Bayonet mount Marie-Lan Nguyen

Micro-Four-Third Lens ▪ Control of – focal length – focus – aperture ▪ Via camera software

Micro-Four-Third Lens ▪ Genicam compliant ▪ GigE Vision compliant ▪ USB3 Vision compliant

Micro-Four-Third Lens ▪ Application know settings of the camera ▪ Full control of all lens settings

Canon Lens ▪ Canon EF-Mount ▪ Known from SLR-market ▪ Adapter solution ▪ Communication to adapter via pins ▪ Communication to camera via cable ▪ Adapter for controlling focus and aperture

Canon EF-Lens ▪ Genicam Compliant ▪ Easy accessible

Applications ▪ Defense ▪ Parcel inspection ▪ Track and Trace / Packaging ▪ Traffic ▪ Automation ▪ High Level Surveillance ▪ Aerial Imaging ▪ Broadcast / Sports
