Image Enhancement Features on Calcomp Scanners
Dual 2D-Adaptive Enhancement
Before Adaptive thresholding	Calcomp scanners are built to provide clean, crisp scans from even poor quality drawings in real-time without preceding pre-scans. The scanners highly sophisticated image processing automatically adapts to the drawing, compensating for varying background, faded areas and stains.
After Adaptive thresholding	Our scanners employ "Dual 2D-Adaptive enhancement processing" that works on the image's foreground, background and other image aspects separately. Dual 2D-Adaptive enhancement processing features include ADL+ error diffusion half-toning, 2D-Adaptive foreground thresholding, 2D-Adaptive background suppression and 2D-Auto edge enhancement.
2D-Sharpening, 2D-Softening and Blur
Calcomp scanners incorporate specialized scanning modes with 2D-Auto edge enhancement, that automatically will sharpen your image while you scan. Through the NEXTimage and JETimage applications, you can manually set and control sharpening, softening and blurring filters, giving you rich possibilities for combining effects to obtain perfect enhancement results.	For example, you may have a drawing or map with details (text, lines) you wish to sharpen. But if the image also contains large concentrated areas of graytones, sharpening will make unwanted noise to appear in the scanned image. By using the sharpen filter together with the blur filter, you can obtain the desired sharpened edges without creating the unwanted noise. Both filters can be set at different levels for ultimate control of effects.

Hardware/Software Processing
	All our Wide Format and Full Scale scanners perform sophisticated image enhancement processing. On our high-level scanner models enhancement processing is embedded in the hardware for optimal speed. On all the other models, image enhancement is supported in Calcomp software - NEXTimage and JETimage.
