A digital “Contrast” correction that lets you for the smart scene optimization based on the dynamic adjustments where various contrast levels happen on relative scene temperature.

Second Generation Digital Detail Enhancement (DDE)

A “Sharpness” correction that digitally improves the images to provide a clear image, significantly enhances the edge sharpening and reduces the image noise.

Smart Scene Optimization (SSO)

A fine-tuning computational correction significantly enhances the overall visual acuity of the targets, which have similar thermal signatures like the surrounding background.

Information Based Histogram Equalization (IBHEQ) 

A “Sky/Sea” enhancement is an information-based environment algorithm that corrects the camera gain automatically and eliminates the determined pixels that don’t contain important information, and especially it is very helpful in the scenes that have lots of sky or water.

Silent Shutterless NUC (SSN)
