| Digitization | 8-bit up to 16-bit signal processing |
|---|---|
| Edge enhancement | Increase contrast at edges |
| Brightness | Increasing of image brightness (offset) |
| Contrast | Contrast increasing/moderation |
| ACC/DRE | Automatic control for contrast and brightness with histogram stretching or equalization |
| Gamma/LUT | Adjustable Gamma function/programmable lookup table |
| Histogram stretching | Contrast/brightness enhancement (using the entire range) |
| HDRadapt | Adaptive luminance algorithm |
| HDR, High Dynamic Range (16-bit) | expanded dynamic range |
| Filter / Memory | Shading correction: adjustable correction (e.g. shading and vignetting) |
| Recursive filter | Adjustable filter for noise reduction by averaging images |
| Bad pixel correction | Correction of defect pixels (hot spots), bright + dark spots |
| Distortion correction | Adjustable correction of pillow-shaped and barrel-shaped distortions |
| Background image subtraction: | Subtraction of a reference image |
| Circular blanking | Circular image window (endoscopy and x-ray applications) |
| Freeze image | Hold current image |
| Mirror / flip | Horizontal/vertical image mirror |
| Negative image | Inversion of the positive image, inverted colors/gray values |
| Image shift | Adjustable X-Y shifting |
| Zoom | Adjustable digital zoom |
Color Processing

| DCIP CMYG: | Color processing for CCD with CyMgYeG Pattern |
|---|---|
| DCIP RGB | Color processing for CCD with Bayer Mosaic Pattern |
| White balance | Automatic or manual white balance |
| Color saturation | Adjustable color saturation |
| Interpolator | Adjustable color saturation |
Exposure
Sie können Ihren Finger benutzen, um die Tabelle horizontal zu scrollen.
| AET: | Automatic exposure time (adjustable target value) |
|---|---|
| AGC | Automatic gain control (adjustable target value) |
| Smear Correction | Automatic correction of smear effects at short exposure times |
| Automatic Level | Target value for AET + AGC |
| Exposure | normal time: exposure = readout time, short (shutter): exposure < readout time, long: exposure > readout time |
Image Format/Readout Modes
Sie können Ihren Finger benutzen, um die Tabelle horizontal zu scrollen.
| ROA, Read out Area: | Adjustable image area for partial scan |
|---|---|
| ROI, Region of Interest | adjustable image area with Frame Mask (AOI area of interest) |
| Binning | Adjustable horizontal and vertical binning for noise reduction and higher frame rates, higher sensitivity |
| Pixel Format (Color Coding) | Mono 8, 10, 12, 14, 16, RGB, YUV, RAW |
| Measurement Window | Measurement basis for automatic functions |
| Readout Mode | Multichannel readout 1, 2, 4 free running, reset/restart, trigger, FoD, GFR-Gated Free Running (trigger controlled free running sequence) |
| Dilution | faster images by “thinning out” pixels |
