Black Box Explains...Super Dynamic II..
This proprietary processing technology developed by Panasonic® eliminates backlighting problems commonly seen with security camera systems. It gives you clear images regardless of the lighting situation and a dynamic range thats 64 times greater than that offered by conventional video cameras.
Super Dynamic II accomplishes this by using a double-speed, charge-coupled device (CCD). It takes two pictures in the time
it takes for a conventional CCD to capture one. The first Super Dynamic II picture is a long exposure (1⁄60th of a second) that captures a scenes dark areas; the second is a short exposure (from 1⁄1000th to 1⁄4000th of a second) that captures the scenes bright areas. Super Dynamic II then combines the best quality signals from the two images and outputs them as a Composite analog image.
The technologys enhanced Digital Signal Processing (DSP) circuitry corrects gradation to give you proper black level references so black areas within a scene appear blacknot washed-out shades of gray. It also enables images with high contrast to be seen on the screen.
Whats more, Super Dynamic II technology provides exceptional sensitivity (0.8 lux using an F1.4 lens), enabling the camera to capture vivid details and color even in low-light applications.
