Centrian™ Camera Tower
by Nigel Ward

Defining the Standard for High Performance Digital Imaging

For over 40 years Digimarc® has provided secure identification solutions. We were the first to introduce photo driver licenses as well as the first to roll out a digital driver license system. Based upon Digimarc’s many years of experience providing thousands of secure ID capture solutions, and having taken over one billion ID photos in the process, we have developed a one-of-a-kind ID capture system. Now for the first time, Digimarc is proud to offer the Centrian™ Camera Tower outside of government programs. The Digimarc Centrian Camera Tower is a state-of-the-art digital imaging system that incorporates high performance and industrial quality components with Digimarc’s proprietary imaging and control technologies. This professional grade system ensures the highest-quality images possible for even the most novice user.

Key Features

  • “Find-A-Face™” Technology — automatically locates the face and then crops, resizes and color corrects the image to simplify user operation.

  • Image file output quality is suitable for biometric applications including facial recognition and facial image database matching.

  • High resolution digital image capture with optical and digital zoom.

  • Ultra-high service life flash with over 250,000 flashes per strobe bulb.

  • Adjustable height suitable for any table or counter installation.

Find-A-Face™ Technology
Digimarc’s proprietary Find-A-FaceTM solution makes taking portraits easy. Camera operators no longer need to reposition the camera and adjust capture settings for different individuals. Instead, the applicant sits in front of the backdrop and the operator simply clicks the capture button.
The camera does the rest automatically.

Capabilities
The application automatically analyzes the applicant’s image and crops it from the background before resizing it to ensure that the subject’s face. Fills the entire portrait area of the ID document. This formatted image is then color and gamma corrected to provide accurate representation of the full range of human skin tone and complexion.

Benefits

  • Fast and easy processing of applicants
  • Reduced operator training
  • Error reduction
  • Consistent, high quality portraits
  • Standardized process, especially useful for multiple operators

Options

  • Centrian Camera Tower API for integration into custom solutions (see below)
  • Functional plug-ins for popular identification badging applications
  • Optional custom badging applications and solutions from Digimarc

Functionality
Applicant is seated. Through live video feed and the “look-right-here” facial alignment, the image is recorded. Next the software locates the applicants face and calculates the appropriate cropping frame. After cropping is completed, Find-A-Face will automatically perform gamma color correction with a “before and after” real time preview screen

The Digimarc Centrian Camera Tower is bundled with an API and a programmer’s reference guide for custom development.

Full SLR camera controls are available through the API
• Capture resolutions up to 4 mega pixels
• Up to 6X optical zoom
• Auto exposure mode
• Auto focus
• Shutter and aperture controls
• Live video feed directly through lens

Auto levels and image adjustments include:
• Brightness
• Contrast
• Gamma corrections

The Centrian Camera Tower, the Easiest Photo ID Capture System to Use on the Market Today.

High-Resolution Digital Portrait Capture
The high-performance digital camera which can capture images up to a resolution of 4 mega pixels. With the millions of photos Digimarc takes each year, we have found this resolution to be ideal for photo ID card applications as well as for biometric applications incorporating facial recognition and facial image matching technologies.

Industrial Quality Flash Unit
Digimarc’s flash unit survives well over 250,000 exposures. The specialized strobe cover diffuses light to ensure proper illumination and eliminates subject squinting and bright spots. Additional ancillary lighting is not necessary.

Optional Shadow Reduction System
Purchase an optional SRS attachment (not shown) to reduce glare introduced by glasses and contact lenses to an imperceptible level. Designed to eliminate shadows to reduce artifacts in laser engraving applications, the Shadow Reduction System ensures clear definitions for black and white and low resolution imaging applications.


The Centrian Camera Tower’s design:

  • Integrates the strobe, camera lens and “look here” features to ensures a perfect photo capture each time; free from over exposures, “red-eye” and other inconsistant results found with lower end systems

  • Eliminates tangled wires and unstable camera and tripod stands

  • Ensures the lens’ protection from scratches, dust and mishandling

  • Allows individuals of varying heights to be captured without requiring the operator to aim or adjust the camera

  • Provides a predrilled base plate for secure mounting

  • Adjusts from minimum height of 28.5” to a maximum of 38” to accommodate either counter or tabletop heights

  • Ensures protection from scratches and dust while protecting the camera unit from impact and mishandling
