# This example shows off using the GenX320 event sensor from Prophesee and controlling
# AntiFlicKer (AFK) filter bloc in the GenX320 digital pipeline.
# AFK allows to detect periodic changes of given frequencies in the scene and filter them out.

import sensor
import time

sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE)  # 必须始终为灰度。
sensor.set_framesize(sensor.B320X320)  # 必须始终为320x320。
sensor.set_framerate(100)

# Enables AFK filter to remove periodic data in the frequency range from 130Hz to 160Hz
sensor.ioctl(sensor.IOCTL_GENX320_SET_AFK, 1, 130, 160)
# Disables AFK filter
# sensor.ioctl(sensor.IOCTL_GENX320_SET_AFK, 0)
