4.1. Function Overview

4.1.1. Objective

  • The video input device supports several kinds of timing input and is responsible for parsing the timing.

  • The video input PIPE is bound to the backend of the device and is responsible for further processing the data after it is parsed by the device.

  • The video input is responsible for outputting the finally processed data to DDR.

4.1.2. Definitions and Abbreviations

  • CIF: Interface of connecting sensor, i.e., MIPI_RX, BT, etc.

  • ISP_FE: Used to output AE, AWB, AF and other statistical data to DDR.

  • ISP_BE: Adjust the quality and color of image input.

  • CHN: Image correction, for image crop, rotation or distortion correction.

  • PHY_PIPE: The physical PIPE is bound to the backend of the device and is responsible for further processing the data after it is parsed by the device.

  • PHY_CHN: The physical video channel is responsible for outputting the finally processed data to DDR. Before actually outputting the data to DDR, it can perform functions such as cropping.
