Member	Description
wnd_rect	The start position of the cropping window, and the width and height of the image, which must be the same as the size in the VI pipe attributes and cannot be greater than the width and height in the bound dev attributes. Otherwise, the image output is abnormal. For details, see hi_rect. The sum of the horizontal start position configured in wnd_rect and the image width must be smaller than the width of the image output by the sensor. The sum of the vertical start position and image height configured in wnd_rect must be smaller than the image height output by the sensor. The actual width and height output by the sensor cannot be detected, so no error is reported when this condition is not met.
sns_size	Image width and height output by the sensor. For details, see hi_size. Value range: [120, 16384]. sns_size must be consistent with the collection attribute of the corresponding sensor.
frame_rate	Frame rate of the input image. Value range: (0.00, 65535.00]
bayer_format	Bayer data format. For details, see hi_isp_bayer_format.
wdr_mode	Selects the WDR mode. For details, see hi_wdr_mode.
sns_mode	Selects the sensor initialization sequence. When the resolution and frame rate are the same, different sns_mode values correspond to different initialization sequences. In other cases, sns_mode is defaulted to 0, and the initialization sequence can be selected by configuring sns_size and frame_rate.
