aus dem Kappa Portfolio



Die hier dargestellte Technik zeigt nur einen Auszug aus dem Portfolio.


Image Processing 
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)
Histogram equalization contrast/brightness enhancement (even distribution)
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 calculation of color values for each pixel from surrounding pixels
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
Character Generator programmable overlays (text, characters, circles, logo)
Line Generator adjustable lines (up to 4)
Circle Generator adjustable circles (up to 2)
On Screen Menu PC-independent adjustment
Mask mask out image areas
Image Format/Readout Modes 
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
FoD Frame on Demand (trigger controlled exposure)
GFR Gated Free Running (trigger controlled free running sequence)
Hardware Trigger external trigger signal
Software Trigger programmable trigger signal (e.g., timer)
Trigger Delay adjustable delay between trigger and exposure
External Synchronization synchronous image sequences
External Clock external pixel clock
PTP Precision Time Protocol for synchronicity of several devices in a network with a master clock (IEEE 1588)
IRIG B protocol for time synchronization
SHA512 hash value calculation for digital signature
Data compression image data compression with H.264 (AVC), MPEG4, MJPEG
Recording real-time recording of image sequences (also HD)
S3D precise calibration and synchronization for 3D Imaging
Streaming GigE Vision 2.0, RTP, RTSP, USB 3 Vision
Tone Mapping compression of color and contrast information of images for monitor display
