4.1. Function Overview

4.1.1. Purpose

  • The video input device supports several timing inputs and parses the input timings.

  • The video input PIPE is bound to the back end of the device and further processes the data parsed by the device.

  • The video input outputs the final processed data to DDR.

4.1.2. Definitions and Abbreviations

  • CIF: the interface connected to the sensor, that isMIPI_RX, BTetc.Interface.

  • ISP_FE: used to output data related to AE, AWB, AF, and other statistics to DDR.

  • ISP_BE: performs image-quality and color adjustments on the input image.

  • CHN: image correction, including cropping, rotation, and distortion correction.

  • PHY_PIPE: the physical PIPE is bound to the back end of the device and is responsible for further processing the data parsed by the device.

  • PHY_CHN: the video physical channel outputs the final processed data to DDR and can perform functions such as cropping before the data is actually output to DDR.
