一般通过修改sensor的不同通道的宽高配置可以设置该通道输出图像分辨率。

    # construct a Sensor object with default configure
    sensor = Sensor()
    # sensor reset
    sensor.reset()
    # set hmirror
    # sensor.set_hmirror(False)
    # sensor vflip
    # sensor.set_vflip(False)

    # set chn0 output size, 1920x1080
    sensor.set_framesize(Sensor.FHD)
    # set chn0 output format
    sensor.set_pixformat(Sensor.YUV420SP)
    # bind sensor chn0 to display layer video 1
    bind_info = sensor.bind_info()
    Display.bind_layer(**bind_info, layer = Display.LAYER_VIDEO1)

    # set chn1 output format
    sensor.set_framesize(width = 640, height = 480, chn = CAM_CHN_ID_1)
    sensor.set_pixformat(Sensor.RGB888, chn = CAM_CHN_ID_1)

    # set chn2 output format
    sensor.set_framesize(width = 640, height = 480, chn = CAM_CHN_ID_2)
    sensor.set_pixformat(Sensor.RGB565, chn = CAM_CHN_ID_2)

    # use hdmi as display output
    Display.init(Display.LT9611, to_ide = True, osd_num = 2)
    # init media manager
    MediaManager.init()
    # sensor start run
    sensor.run()

如上述代码中修改通道1的输出分辨率可以设置sensor.set_framesize(width = 640, height = 480, chn = CAM_CHN_ID_1)中的width和height属性。
