Ch. 3 – Basic Program 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.Taking a PictureThe actual capture of a digital image (taking the picture) is similar to traditional photographic techniques.In digital photography, however, it is possible to continually capture, refine, and recapture images until youhave an optimal representation: the first image that you capture might be only one of several that you use toproduce a publishable product. A sample image capture process, from start to finish might proceed asfollows:1. Adjust the Preferences as needed (see above).2. Open the Live Image window.3. Frame and focus the image as needed.4. Click on the Image Settings toolbar button to access the Image Settings window and adjust the liveimage view settings.5. Click on the Get Image toolbar button to capture the final image.In the Basic program mode, image captures settings and live image view settings are defined from the samesource - the Image Settings window. This gives you the convenience of being able to view a live image,adjust the settings in real-time, and then capture the image with the live image view settings.Note: Except for the Captured Image Bit Depth, which is defined on the Preferences window, allimage capture/live image settings are defined from the Image Settings window.Initialize CameraIf you turned on the SPOT power supply after you opened the program, you need to initialize the camera inorder to activate all of the capture and editing options. To do so, select the Initialize option from theCamera menu.User Guide to the SPOT Insight Camera 41
