The Image Statistics Engine LogiCOREâ„¢ 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.
