IP_SPort – Sensor Port
This IP Sensor Port allows to reconstruct the standard signals for both CMOS and CCD interface sensors. The IP_SPort for CCD generates the timing pulses for performing progressive scan for CCD image sensor.
Key features
- Selectable bitwidth for input pixel data, HDR ready
- Integrated gain stage with selectable fixed-point precision bits for each RGB color channel
- Integrated I2C or SPI interface
- Dynamic setup via Wishbone
- Sensor interface for CCD and CMOS

IP_Stat – Statistics
This IP core provides pixel sum and pixel numbers for each color channel. This information is used for example by the AWB algorithms.
Key features
- Selectable bitwidth for input pixel data, HDR ready
- Column and row counter
- Freely adjustable ROI
- Counters for number of pixels in ROI, saturated pixels, etc.
- Dynamic setup via Wishbone
IP AWB/AGC – Automatic White Balance Automatic Gain Control
This IP core is aimed at automatically adjusts both the gain and the white balance of the scene to a neutral setting regardless of the ambient light source.
Key features
- Feedback from statistics
- Online optimal gain computation for each frame
- Set computed gain value to sensor register and FGPA register via a master Whisbone interface
- Customizable algorithm
- Resource optimized sMico32 calculation engine
IP_DBY – Debayering
This IP core is aimed at reconstructing the full color information for each sensor pixel. Several interpolation algorithms have been developed. The IP core allows to obtain a full color image where for each pixel a full set of R, G, B values are provided by interpolation. This results in a high-quality image.
Key features
- Selectable bitwidth for input pixel data, HDR ready
- Selectable maximum picture column size
- 3×3 bilinear, 5×5 high-quality
- Dynamic setup via Wishbone
- Border extrapolation

IP_CCM – Color Correction Matrix
Often the images acquired from a sensor have wrong colors . This is due to the cross color effect. The IP core corrects colors applying a correction matrix to each pixel.
Key features
- Selectable bitwidth for each color channel data, HDR ready
- Selectable bitwidth for coefficients /selectable fixed-point bits
- Full color RGB in- and output
- Auto saturation detection
- Dynamic setup via Wishbone
- Each matrix coefficient is a fixed-point number
IP_GC – Gamma Correction
The gamma correction allows to modify the relationship between a pixel’s numerical value and its actual luminance from a linear to non-linear relation.
Key features
- Selectable bitwidth for each color channel data, HDR ready
- Selectable output datawidth
- Automatic interpolation between look up table entries
- Separate correction for each single color channel
- Dynamic Setup via Wishbone
- Gamma Compression or expansion possible to switch during processing
IP_OV – Overlay
This IP core add text or graphics to a video stream. This allows to implement On-Screen Display function.
Key features
- Adjustable overlay position
- Selectable number of different colors
- 32-Bit per color
- Dynamic setup via Wishbone
