DCMIPP ISP example utility

Applicable for

STM32MP25x lines

---

1. Overview

isp is a utility developped by STMicroelectronics to demonstrate the DCMIPP ISP capabilities regarding image correction based on STMicroelectronics basic correction algorithms. Refer to How to use the DCMIPP ISP article to have some details on how to implement such a utility and put in place your own custom correction algorithms.
