IP Description: 

Histogram equalization is useful technique for expanding the contrast range of low contrast images allowing details to be perceived that were previously invisible. It is particularly helpful in extreme lighting conditions such as can be met in security imaging where lighting cannot be controlled or in scientific and industrial imaging. It may also be used to pre-condition images for further processing such as feature extraction.

PT10 calculates the histogram of the image intensities in real time and applies the correction to the following video frame, calculating the correction during the vertical blanking interval.

Control and status registers are written to and read from using a conventional 8 bit wide microprocessor interface.

A demonstrator/evaluation board is available.

PT10 is a histogram equalization IP core, suitable for both SD and HD video sources.
