像这样同样一个物体为什么会识别出三个颜色块的值呢，能不能只让他输出一个最符合的颜色

sensor.reset()
#sensor.set_vflip(True)
#sensor.set_hmirror(True) #倒放
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQQVGA) # 80x60 (4,800 pixels) - O(N^2) max = 2,3040,000.
#sensor.set_windowing([0,10,80,50]) #(x,y,w,h)
sensor.skip_frames(time = 2000) # WARNING: If you use QQVGA it may take seconds
clock = time.clock() # to process a frame sometimes.

while(True):
clock.tick()
img = sensor.snapshot().binary([THRESHOLD])
img_color = sensor.snapshot()

像这样，我能不能拍两个不同类型的图片，然后对两个图片分别做处理，他们之间是互不影响的吗？

使用openmv H7 plus训练神经网络怎么在拍摄照片时提高准确度


像这样的图片，怎么拍摄能让这个电池的特征更加明显

import time
from pyb import LED

red_led = LED(1)
green_led = LED(2)
blue_led = LED(3)
ir_led = LED(4)

while(True):
LED(1).on()
time.sleep_ms(900)
LED(1).off()
time.sleep_ms(900)
LED(2).on()
time.sleep_ms(900)
LED(2).off()
time.sleep_ms(900)
LED(3).on()
time.sleep_ms(900)
LED(3).off()
time.sleep_ms(900)
LED(4).on()
time.sleep_ms(900)
LED(4).off()
time.sleep_ms(900)

openmv H7 plus
1、运行这段代码时只有红圈圈出来的灯在亮，而且LED(4).on()怎么没有白色灯光啊，我需要白色光。
2、白圈圈出来的那两个灯怎么点亮啊？
3、openmv可以一直让灯常亮吗？

我在做神经网络提交数据集时，输入了API key 之后显示这个，这是怎么回事
