The Image Statistics Engine LogiCORE™ IP provides hardware-based image analysis to support Auto-Focus, Auto-Exposure, and Auto-White balance applications.
The Image Statistics LogiCORE IP implements the computationally-intensive metering functionality common in digital cameras, camcorders and imaging devices. This core generates a set of statistics for color histograms, mean and variance values, edge and frequency content for 16 user defined zones on a per frame basis. The statistical information collected is used in the control loops for Auto-Focus Auto-White Balance and Auto-Exposure in image processing applications.
Key Features
- Support for up to full high-definition (1080p60) resolutions
- 16 programmable zones
- Support for 8, 10, or 12-bit input precision
- Multiple output data values for all zones and color channels
- Sum and sum of squares of color values
- Low and high frequency content
- Horizontal, vertical, diagonal and anti-diagonal edge content
- Outputs for pre-selected zone(s):
- Y channel histogram
- R,G,B channel histograms
- Two dimensional Cr-Cb histogram
