AGM Global Vision
All Cobra devices are based on FLIR Tau 2 cameras that allow for improvements in overall image
quality in a wide range of dynamic thermal environments. The Cobra has employed special user-
adjustable imaging tools that include:
•
Active Contrast Enhancement (ACE) – a digital “Contrast” correction that allows for smart
scene optimization based on dynamic adjustments, where a variety of contrast levels occur
depending on relative scene temperature.
• Second Generation Digital Detail Enhancement (DDE) – a “Sharpness” correction that
digitally enhances the picture, significantly sharpens edges, and further reduces image noise.
•
Smart Scene Optimization (SSO) – a fine-tuning computational correction that significantly
improves overall visual acuity for targets that have thermal signatures similar to the surrounding
background.
• Information-Based Histogram Equalization (IBHEQ) – a “Sky/Sea” enhancement –
information-based environment dependent algorithm that automatically adjusts camera gain and
excludes pixels determined to not contain critical information. Specifically helpful in scenes with
great expanses of visible sky or water.
•
User-Controlled Manual Non-Uniformity Correction/ Flat-Field Correction (UCMNUC/ FFC).
There is a mechanical shutter between the camera sensor and the lens. This shutter is used to
perform a non-uniformity correction (NUC), also known as flat-field correction (FFC). During FFC,
the shutter presents a uniform temperature source to each detector element in the array. While
imaging the flat-field source, the camera updates the offset correction coefficients, resulting in
a more uniform image after the process is complete. All Cobra models allow for user to manually
trigger or interrupt scheduled UCMNUC/ FFC function.
•
Silent Shutterless NUC™ (SSN) – In addition to User-Controlled Manual NUC/ FFC, all Cobra
models employ a digital, supplemental, non-mechanical flat-field correction that extends periods
between mechanical shutter events and further reduces image noise. SSN is an always ON
enhancement.
Information on the current operating state (battery status, active function in the display etc.) is
continuously displayed, making field operation of the Cobra simple and convenient.
Manufactured for exceptional durability, the Cobra has a lightweight and robust aluminum body.
A side Picatinny/ Weaver rail allows for the installation of an optional Digital Video Recorder,
extended battery pack, or other equipment.
A standard NTSC/PAL video input/ output connector enables an external video display (monitor/
TV) or video recorder to be connected to the Cobra. An external 6VDC/600mA power source can
also be connected to the Cobra.
The Cobra is powered by two CR123A (2×3V) batteries.
Figure 1-2 shows the Cobra. The ITEM NO. column of Table 2-1 indicates the number used to
identify items in Figure 1-2.
NOTE:
Here and below, the example used is the Cobra with a 50mm lens.
