不知道为什么会出现这种问题。。。新人求教，源代码如下
import sensor,image,time

red_threshold_01=(0,35,0,50,-10,40)

sensor.reset()
sensor.set_pixformat(sensor,RGB565)
sensor.set_framesize(sensor.QQVGA)
sensor,skip_frames(10)
sensor.set_auto_whitebal(False)

clock=time.clock()
while(True):

clock.tick()
img=sensor.snapshot()
blobs=img.find_blobs([red_threshold_01],area_threshold=150)

if blobs:
    print(blobs)
    for b in blobs:
        img.draw_rectangle(b[0:4])
        img.draw_cross(b[5],b[6])
print(clock.fps())

是sensor.RGB565

中间是 点 而不是 逗号
