那我在网上购买一个变焦摄像头，配合相应固件可以实现自动调焦吗

我看官方提供的数据手册OV5640是有自动调焦功能的呀

如果我想外接一个1080P的屏幕，需要改变官网的代码吗，官方自带的屏幕分辨率有点低，有什么推荐的办法吗

想问一下如何调节图片色温呢？感谢！！

import sensor, image, time

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.WQXGA2)
sensor.skip_frames(time = 2000)
clock = time.clock()

while(True):
    clock.tick()

    # A clip_limit of < 0 gives you normal adaptive histogram equalization
    # which may result in huge amounts of contrast noise...

    # A clip_limit of 1 does nothing. For best results go slightly higher
    # than 1 like below. The higher you go the closer you get back to
    # standard adaptive histogram equalization with huge contrast swings.
    
    
    img = sensor.snapshot().histeq(adaptive=True, clip_limit=3)
    img = sensor.snapshot().gamma_corr(gamma = 1.3, contrast = 1.0, brightness = 0.0)
    print(clock.fps())
