Members

Member	Description
pfn_cmos_get_ae_default	Pointer to the callback function for obtaining the initial value of the AE algorithm library
pfn_cmos_fps_set	Sets the frame rate for a sensor.
pfn_cmos_slow_framerate_set	Sets the frame rate reduction of a sensor. Pegasus Auto V100R003C10: This callback function is not called in vehicle-mounted scenarios. You are advised to set it to NULL.
pfn_cmos_inttime_update	Sets the exposure time of a sensor.
pfn_cmos_gains_update	Sets the analog gain and digital gain of a sensor.
pfn_cmos_again_calc_table	Computes the analog gain of the table sensor.
pfn_cmos_dgain_calc_table	Computes the digital gain of the table sensor.
pfn_cmos_get_inttime_max	Pointer to the callback function for computing the maximum exposure time of short frames in WDR mode, which is closely related to the sensor.
pfn_cmos_ae_fswdr_attr_set	Pointer to the callback function for setting the long frame mode in 2to1LineWDR mode Pegasus Auto V100R003C10: This function is not involved in vehicle-mounted scenarios. You are advised to set it to NULL.
pfn_cmos_ae_quick_start_status_set	Sets the AE no-light-sensor quick start convergence status. Pegasus Auto V100R003C10: This callback function is not called in vehicle-mounted scenarios. You are advised to set it to NULL.
pfn_cmos_exp_param_convert	Converts exposure parameters at different frame rates, which is implemented together with hi_mpi_isp_get_exp_convert. Pegasus Auto V100R003C10: This callback function is not called in vehicle-mounted scenarios. You are advised to set it to NULL.

Restrictions

If the callback function pointer does not need to be assigned a value, set it to null.
The exposure time accuracy and gain is defined in hi_isp_ae_sensor_default. The exposure time and gain configured in pfn_cmos_inttime_update and pfn_cmos_gains_update are values with accuracy. How to convert them into the configured values of the sensor is closely related to the sensor. For details, see the sensor manual.
If the no-light-sensor quick start function is not used, pfn_cmos_ae_quick_start_status_set must be set to null.
quick_start_status is the flag bit of the AE no-light-sensor quick start convergence status. When this parameter is set to HI_TRUE, no-light-sensor quick start convergence is complete.
