Introduction

The document provides basic information about the Image Signal Processing (ISP) block in the StarFive SoC JH7110 and the associated ISP drivers developed under Linux OS. Driver architecture and related APIs are explained with examples and details.

The Image Signal Processor (ISP) processes digital images by using a series of digital image processing algorithms. The ISP supports the following functions: 3A algorithm, black level correction, lens shading correction, gamma correction, local tone mapping, edge enhancement, noise reduction, and color enhancement. The ISP consists of the logic and firmware running on the logic.
