SPOT 4.1 Basic and Advanced Software Manual for SPOT Insight ...

Ch. 15 – Using Other Windows Imaging Applications in Basic ModeNoise FilterThe Noise Filter corrects for the effects of electrical or thermal noise. When capturing dim images withlengthy exposure times, the noise filter acts as a “virtual cooler” for the Insight camera, eliminating “hotpixels.”The Noise Filter checks each pixel on the CCD chip as described below:1. The program compares the value of each red pixel with the values of the eight neighboring red pixels.2. If none of the eight neighboring red pixels has a value within ±15 % (i.e., the threshold value that theSPOT program uses) of the value for the red pixel being checked, the value for the red pixel beingchecked is replaced with the average value of the eight neighboring red pixels.3. The program repeats this procedure for the values of the green and blue pixels being checked.To activate the Noise Filter, check the Noise Filter box. The program runs the noise filter each time animage is captured using the Preview or Acquire options.DeviceClicking on the device button allows you to select the camera that you would like to use (or switch to) forthe next image capture. This window is identical to the device selection window that appears when youopen the SPOT software program.Taking a PictureFrom the SPOT TWAIN Interface, you can capture images in different ways:• Preview - You can capture a Preview image. Preview images remain available in the TWAINwindow for basic editing and serve as the basis for the final image capture. When you click on thePreview button, the Get Image dialog displays the capture status as it is captured, and the capturedimage then replaces in the Live Image in the window. Note that the status bar indicated that you areviewing a Preview image.• Transfer - If you like the Preview image, you can Transfer it image directly to the third partyapplication that you are using. The Transfer button is active only for Preview image captures.• Acquire - Capture an image and have it automatically transfer to (open in) the third party imagingapplication.User Guide to the SPOT Insight Camera 289
