X-LINUX-ISP expansion package

1. What is X-LINUX-ISP?[edit | edit source]

X-LINUX-ISP is a free-of-charge open-source software package providing Image Signal Processing (ISP) image quality software. It targets the STM32MP25xx microprocessors in the STM32MP2 series that embed an ISP camera pipeline called DCMIPP.
It brings advanced image quality capabilities for developers working with OpenSTLinux to create an ISP-based application very easily.

• Pre-integrated into Linux^® the distributions based on ST environment
• libcamera included, with the support of the DCMIPP ISP Image Processing Algorithm (IPA) integrating Auto Exposure (AE), Auto White Balance (AWB), and all ISP controls
• libcamerasrc gstreamer plugin included, supporting DCMIPP ISP properties
• Sensor tuning application included, to access the ISP configuration and perform a sensor tuning procedure; it runs on the target and interacts with the STM32 ISP IQTune desktop application executed on the host computer (connected through USB)
• Simple ISP preview application example included, taking advantage of libcamera and libcamerasrc gstreamer plugin for easy prototyping
• Delivered under GitHub as a Yocto meta-layer
