1. Overview[edit | edit source]
The DCMIPP ISP example utility named "isp" is a software utility developed 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 an utility and put in place your own custom correction algorithms.
