ISP stands for Image Signal Processor. It is a dedicated processor or hardware IP core that performs a series of processing including noise reduction, white balance, color correction, and demosaicing on the RAW data output from image sensors, ultimately generating high-quality digital images.

With the advent of the artificial intelligence (AI) era, vision has become increasingly important. ISP is no longer only integrated into traditional image DSP, IPC SoC, and AI CIS chips; it is also being integrated into various chips such as AI SoC, WIFI/BLE SoC, AR/VR, MPU, and MCU.
