硬件

图片在IDE里看到和在SD卡里保存的图片都是错位的

@kidswong999 我就是这样写的，拍三张照片，第一张没事，第二张就这样了

import cpufreq
import pyb
import sensor,image, time,math
from pyb import LED,Timer,UART

sensor.reset()                      # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QQVGA)  # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000)     #延时跳过一些帧，等待感光元件变稳定
sensor.set_auto_gain(False)
sensor.set_auto_whitebal(False)
clock = time.clock()                # Create a clock object to track the FPS.
sensor.set_auto_exposure(True, exposure_us=5000) # 设置自动曝光
qrcodes_flag=0
def opv_find_qrcodes():

    #sensor.skip_frames(30)
    global qrcodes_flag
    sensor.set_auto_gain(False)
    img = sensor.snapshot()
    img.lens_corr(1.5) # strength of 1.8 is good for the 2.8mm lens.
    for code in img.find_qrcodes():
        clock.tick()
        img.draw_rectangle(code[0:4])
        qrcodes_flag += 1
        if(qrcodes_flag==5 ):#
            img.save("/example1.jpg")
        if(qrcodes_flag==10):#
            img.save("/example2.jpg")
        if(qrcodes_flag==15):#
            img.save("/example3.jpg")
        print(code)

opv_find_qrcodes()

我也有这种问题
