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.

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.
