micropython-camera模块怎么调整像素

poind

调用micropython的camera模块成功，但是不能调整像素大小，只能使用默认的648*480
我查询了一下opencv的资料，并设置camera的参数，但是不起效果
camera.init(0, resolution=(desired_width, desired_height), format=camera.JPEG)
camera.init(第几个相机, resolution=(desired_照片宽度, desired_照片高度), format=camera.JPEG【相片格式】)
代码如下：import time
import uos
from machine import SDCard
import camera
i = 0
try:
    uos.mount(SDCard(), "/sd")
except Exception as ret:
    print("loading erro...", ret)
else:
    print("loading pass...")
try:
    camera.init(0, format=camera.JPEG)
except Exception as e:
    camera.deinit()
    camera.init(0, format=camera.JPEG)
while True:
    # 拍摄一张图片
    time.sleep(15)
   buf = camera.capture()  # 大小是640x480
    if not buf:
        print("Failed to grab frame")
        break
    i = i + 1
    timestamp = time.localtime()
    date_str = "{}{:02d}{:02d}".format(timestamp[0], timestamp[1], timestamp[2])
    filename = "/sd/{}_the{:04d}picture.jpg".format(date_str, i)

    with open(filename, "wb") as f:
        f.write(buf)
        print("picture complete:", filename)
camera.deinit()

设置分辨率（不设置分辨率默认是200万像素）
camera.framesize(camera.FRAME_240X240)
分辨率参数：
camera.FRAME_96X96   96x96
camera.FRAME_240X240   240x240
camera.FRAME_QVGA    320X240
camera.FRAME_VGA   640x480
camera.FRAME_SVGA    800x600
camera.FRAME_HD     1280X720
