Pelco TI2550 manual Changing the POLARITY/LUT Setting, PAN and Zoom

CHANGING THE POLARITY/LUT SETTING

The Polarity/LUT setting programs the specific palette of colors to represent the temperatures in the thermal image. These colors are not calibrated to a specific temperature. Rather, they represent the temperature variations within the thermal image. The following table lists the available display types and their color palettes. These palettes show the range of colors from hot temperatures to cold temperatures.

PAN AND ZOOM

Zoom 2x

The camera has a built-in 2X digital zoom capability. The “Zoom 2x” check box is used to turn on/off the camera zoom. With the check box cleared, the camera displays the image at full resolution (320 x 240 NTSC or 320 x 256 PAL). This full-resolution image is also called the full-array area.

When the “Zoom 2x” check box is selected, a smaller portion of the video displays, creating a zoom effect. This reduced, or “zoomed,” area of the video is called the zoomed array region.
