在使用snapshot（copy_to_fb=False）时，IDE缓冲区还是能看到图像，这是为啥？

[grnm]

import time, sensor, image
from image import SEARCH_EX, SEARCH_DS


sensor.reset()


sensor.set_contrast(1)
sensor.set_gainceiling(16)

sensor.set_framesize(sensor.VGA)

sensor.set_pixformat(sensor.GRAYSCALE)


clock = time.clock()


while (True):
    clock.tick()
    img = sensor.snapshot(copy_to_fb=False)
    print(clock.fps())

copy_to_fb不会起作用，因为这个函数不能传递参数。
