请问大佬v831采集图像后二值化报错怎么回事

[lq15130619587]

在windows上用的maixpy3ide
代码部分：
from maix import image, display, camera
THRESHOLD = [(34, 100, -38, 3, -128, -28)]
while True:
img = camera.capture().binary(THRESHOLD, invert=False, zero=False)
display.show(img)

报错：_get_exception_class.<locals>.Derived: '_maix_image.Image' object has no attribute 'binary'
