Defines the attributes of a VI device.

Definition

typedef struct {
    hi_vi_intf_mode      intf_mode;
    hi_vi_scan_mode      scan_mode;
    hi_vi_data_seq       data_seq;
    hi_vi_data_type      data_type;
    hi_size              in_size;

For details about basic data type hi_u32, see Basic Data Types.

Members

Member	Description
intf_mode	Interface mode. For details, see hi_vi_intf_mode.
scan_mode	Input scanning mode (progressive or interlaced). Currently, only progressive scanning is supported. For details, see hi_vi_scan_mode.
data_seq	Input sequence of the YUV data. Only the YUV format is supported, such as VUVU or UVUV. If data_type is set to HI_VI_DATA_TYPE_YUV, you need to configure data_seq. For details, see hi_vi_data_seq.
data_type	Input data type. Generally, the sensor input is raw data. The sensor input of some embedded ISPs can also be YUV. For details, see hi_vi_data_type.
in_size	Height and width of the image that can be captured by the VI device. For details, see hi_size. The value ranges of the width and height for the captured image are shown as follows: Width: [120, 16384] Height: [120, 16384]
wdr_addr	WDR attribute. For details, see hi_vi_wdr_attr.
data_rate	Device rate: one pixel per cycle or two pixels per cycle. Only one pixel per cycle is supported. For details, see hi_data_rate.
reserved	Reserved. To ensure compatibility in later versions, use the memset structure for resetting and initialization. Do not explicitly access the reserved field in the code.
