我想实现拍一张照片，再实时传输到浏览器，如此不断循环，所以先进行单次测试，拍一张传一张，发四次。
但是，看浏览器结果像是第一次不知道传输了什么，第二次传输了1.jpg，第三次传输了2.jpg，第四次传输了3.jpg，结束。
再添加重复代码也是类似的情况，会有一张的差距，我想问是什么原因造成的，怎么才能实时传输图片？

测试采用IDE 2.4.0例程mjpeg_streamer，手机和openmv连接同一个WiFi，手机用UC浏览器连接IP:8080
代码中
import pyb #用于延时
将传输部分

    while (True):
        clock.tick() # Track elapsed milliseconds between snapshots().
        frame = sensor.snapshot()
        cframe = frame.compressed(quality=35)
        header = "\r\n--openmv\r\n" \
                 "Content-Type: image/jpeg\r\n"\
                 "Content-Length:"+str(cframe.size())+"\r\n\r\n"
        client.send(header)
        client.send(cframe)
        print(clock.fps())

替换为四段重复代码

    num=0  
    
    num+=1
    frame = sensor.snapshot()
    frame.draw_string(5, 0, "%02d"%num, color = (128, 0, 0), scale = 2, mono_space = False)
    cframe = frame.compressed(quality=35)
    header = "\r\n--openmv\r\n" \
             "Content-Type: image/jpeg\r\n"\
             "Content-Length:"+str(cframe.size())+"\r\n\r\n"
    client.send(header)
    client.send(cframe)
    print(num)
    pyb.delay(3000)

    num+=1
    frame = sensor.snapshot()
    frame.draw_string(5, 0, "%02d"%num, color = (128, 0, 0), scale = 2, mono_space = False)
    cframe = frame.compressed(quality=35)
    header = "\r\n--openmv\r\n" \
             "Content-Type: image/jpeg\r\n"\
             "Content-Length:"+str(cframe.size())+"\r\n\r\n"
    client.send(header)
    client.send(cframe) 
    print(num)
    pyb.delay(3000)
    
    num+=1
    frame = sensor.snapshot()
    frame.draw_string(5, 0, "%02d"%num, color = (128, 0, 0), scale = 2, mono_space = False)
    cframe = frame.compressed(quality=35)
    header = "\r\n--openmv\r\n" \
             "Content-Type: image/jpeg\r\n"\
             "Content-Length:"+str(cframe.size())+"\r\n\r\n"
    client.send(header)
    client.send(cframe) 
    print(num)
    pyb.delay(3000)
    
    num+=1
    frame = sensor.snapshot()
    frame.draw_string(5, 0, "%02d"%num, color = (128, 0, 0), scale = 2, mono_space = False)
    cframe = frame.compressed(quality=35)
    header = "\r\n--openmv\r\n" \
             "Content-Type: image/jpeg\r\n"\
             "Content-Length:"+str(cframe.size())+"\r\n\r\n"
    client.send(header)
    client.send(cframe) 
    print(num)
    pyb.delay(3000)

    while True:pass
