@kidswong999 这种情况能通过擦COMS来改善么

@kidswong999 在 新买的openmv4plus在rpg565下拍摄的图片发绿发暗 中说：

sensor

这暗的过头了，而且他发绿啊 ，能有能正常拍摄的摄像头套件来替换么，还是只能进行物理补光

新买的openmv4plus在rpg565下拍摄的图片发绿发暗，同样的代码在之前的openmv3上就没有任何问题，用的都是历程，这属于硬件问题么？

请在这里粘贴代码
```import sensor, image, time
import json
from pyb import UART
# For color tracking to work really well you should ideally be in a very, very,
# very, controlled enviroment where the lighting is constant...
yellow_threshold   = ( 46,  100,  -68,   72,   58,   92)
# You may need to tweak the above settings for tracking green things...
# Select an area in the Framebuffer to copy the color settings.

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # use RGB565.
sensor.set_framesize(sensor.QQVGA) # use QQVGA for speed.
sensor.skip_frames(10) # Let new settings take affect.
sensor.set_auto_whitebal(False) # turn this off.
clock = time.clock() # Tracks FPS.

uart = UART(3, 115200)

while(True):
    clock.tick() # Track elapsed milliseconds between snapshots().
    img = sensor.snapshot() # Take a picture and return the image.

    blobs = img.find_blobs([yellow_threshold])
    if blobs:
        #print('sum : %d'% len(blobs))
        data=[]
        for b in blobs:
            # Draw a rect around the blob.
            img.draw_rectangle(b.rect()) # rect
            img.draw_cross(b.cx(), b.cy()) # cx, cy
            data.append((b.cx(),b.cy()))

        #{(1,22),(-3,33),(22222,0),(9999,12),(0,0)}
        data_out = json.dumps(set(data))
        uart.write(data_out +'\n')
        print('you send:',data_out)
    else:
        print("not found!")
