openmv4PLUS的图像为什么这么偏暗偏绿

[dpt5]

感觉过头了，白天好一些，色块经常都不灵，openmv4就感觉还正常



实际灯挺亮的
下面是openmv4的图像

代码里面白平衡，曝光什么的也开了，没什么效果
plus就这样的吗，还是我哪里做的不对

提供一下具体的代码。

@kidswong999 跑例程就是这样的效果

# Hello World Example
#
# Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script!

import sensor, image, time

sensor.reset()                      # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000)     # Wait for settings take effect.
clock = time.clock()                # Create a clock object to track the FPS.

while(True):
    clock.tick()                    # Update the FPS clock.
    img = sensor.snapshot()         # Take a picture and return the image.
    print(clock.fps())              # Note: OpenMV Cam runs about half as fast when connected

@kidswong999 是硬件的问题吗

应该是环境太暗了。你运行下面的代码。

import sensor, image, time

sensor.reset()                      # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA)   # Set frame size to QVGA (320x240)
sensor.set_auto_whitebal(False, rgb_gain_db=(62,60,63))
sensor.set_auto_exposure(False, 101244)
sensor.set_auto_gain(False, 22)
sensor.skip_frames(time = 2000)     # Wait for settings take effect.
clock = time.clock()                # Create a clock object to track the FPS.

while(True):
    clock.tick()                    # Update the FPS clock.
    img = sensor.snapshot()         # Take a picture and return the image.
    print(clock.fps())

@kidswong999 可能好一点了，但还是感觉偏暗

下面是用手机拍的

那你就把里面的曝光值再大一些
