Description

sns_type

Type of the communication interface between the sensor and the ISP

reg_num

Number of registers to be configured when the exposure result is written to the sensor. Dynamic change is not supported.

cfg2_valid_delay_max

Maximum number of delayed frames from the time when all sensor registers are configured to the time when the registers take effect. This parameter is used to ensure the synchronization between sensor registers and ISP registers. Generally, the exposure time register of the CMOS sensor has the maximum delay, one or two frames. Therefore, the value is 1 or 2.

exp_distance

In WDR mode, the sensor exposes the line difference between the long frame and the medium frame, the line difference between the medium frame and the short frame, and the line difference between the short frame and the short frame. This attribute is reserved and is not supported currently.

com_bus

ID of the device bound to the sensor

i2c_data

IC2 data parameter

ssp_data

SSP data parameter

update

Whether the data configures the sensor register.

HI_TRUE: The sensor register is configured.

HI_FALSE: The sensor register is not configured.

delay_frame_num

Number of delayed frames for the sensor register. This variable is used to ensure that the exposure time and gain take effect at the same time.

slave_vs_time

XVS signal cycle (unit: cycle of the sensor input clock)

slave_bind_dev

Relationship between the slave device ID and vi_pipe

config

Data configuration completion flag of the sensor register.

  • TD_TRUE: configuration complete.
  • TD_FALSE: not configured.

Restrictions

None
