Color Correction Matrix
The AXI Color Correction Matrix (CCM) core is used to implement various color corrections in
the image processing pipeline (Figure 42):
• White balance
• Brightness
• Contrast
• Saturation

Software
Platform
An application to demonstrate the capabilities of the Zynq-7000 AP SoC PS and PL
combination for mainstream video embedded systems is implemented on top of Linux
kernel 3.x. Developers can tailor Linux to their particular applications by porting their
applications and customizing open source software packages. The pre-verified Linux platform
enables rapid software platform modification to adapt to hardware changes.
Zynq-7000 AP SoC-based 1080p60 Camera Application
A unified and multi-threaded Linux software application is implemented to demonstrate the
capabilities of the Zynq-7000 AP SoC PS and PL combination for mainstream video embedded
systems. The main application initializes the video processing pipeline, and allows design
configuration via the USB-serial connection or via the network with a web-based GUI.
