Armasight Prometheus C 336 2-8x25 User Manual page 9

To accommodate individual user needs, the Prometheus C has a variety of digitally controlled options
such as:
• Display Brightness
• Digital Zoom
• Palette Color Selection
• User-Controlled Manual Non-Uniformity Correction/ Flat-Field Correction (UCMNUC/ FFC)
• Imaging Enhancements
• Custom Settings
All Prometheus C devices are based on FLIR Tau 2.7.2 or later cameras that allow for improvements in
overall image quality in a wide range of dynamic thermal environments. The Prometheus C 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.
• Automatic Gain Control (AGC) – a "Gain" correction that used to automatically adjust the gain
to an appropriate range, the weaker the image signal, the stronger the gain.
• 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 Prometheus C 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
Prometheus C 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 Prometheus C simple and convenient.
Manufactured for exceptional durability, the Prometheus C has a lightweight and robust aluminum body.
The Prometheus C can be mounted to a tripod with 1/4'' threaded socket located on the body of the
device.
