Members
Member |
Description |
|---|---|
pfn_cmos_sensor_init |
Pointer to the callback function for initializing the sensor. |
pfn_cmos_sensor_exit |
Pointer to the callback function for exiting the sensor. |
pfn_cmos_sensor_global_init |
Pointer to the callback function for initializing global variables. |
pfn_cmos_set_image_mode |
Pointer to the callback function for switching the resolution and frame rate. Return value 0 indicates that the sensor mode changes. In this case, the ISP calls pfn_cmos_sensor_init to reconfigure the sensor. Return value -2 indicates that the sensor mode does not change and the ISP does not reconfigure the sensor. |
pfn_cmos_set_wdr_mode |
Pointer to the callback function for setting the WDR mode. |
pfn_cmos_get_isp_default |
Pointer to the callback function for obtaining the initial value of the ISP base algorithm. |
pfn_cmos_get_isp_black_level |
Pointer to the callback function for obtaining the sensor black level. The black level can be dynamically adjusted based on the sensor gain. In this case, you can dynamically adjust the black level only by using the manual mode of hi_mpi_isp_set_black_level_attr. |
pfn_cmos_get_sns_reg_info |
Pointer to the callback function for obtaining sensor register information. It is used to configure the AE in kernel mode. |
pfn_cmos_set_pixel_detect |
Pointer to the callback function for enabling or disabling defect pixel correction. |
pfn_cmos_notify_event |
This interface is used to notify the module driver of special events, such as the sleep wakeup event, so that the module can perform partial logic processing.

Precautions
- Values must be assigned to members pfn_cmos_sensor_init, pfn_cmos_get_isp_default, pfn_cmos_get_isp_black_level, pfn_cmos_set_pixel_detect, and pfn_cmos_get_sns_reg_info. If no values need to be assigned to other callback function pointers, set these pointers to NULL. For example, pfn_cmos_set_image_mode needs to be set to NULL if a sensor that does not support resolution switching is used.
- The configuration position of the AWB gain cannot be changed.
