IMX335 设置2592分辨率

Question

问题描述

我用IMX335的相机模组。查看Sensor的API介绍，IMX335是支持2592x1944这个分辨率的。我因为项目需要，必须要用高分辨率的图片进行识别。
我在代码里面设置1920x1080是可以正常使用的，但是设置成2592x1944，直接报错。
报出的错误提示如下：
[错误] 摄像头初始化失败: sensor(0) chn(0) set_framesize invaild width(2592), should be 64 - 1920

复现步骤

    camera = Sensor(id=1)
    camera.reset()
    camera.set_framesize(width=2592, height=1944)        camera.set_pixformat(camera.RGB565)
    from media.media import MediaManager
    MediaManager.init()
    camera.run()

#-----这个是示例代码，我用这个代码用1080P显示不了视频-----------#
print("camera_test")

# construct a Sensor object with default configure
sensor = Sensor(id=0)
# sensor reset
sensor.reset()
# set hmirror
# sensor.set_hmirror(False)
# sensor vflip
# sensor.set_vflip(False)

# set chn0 output size, 800x480
sensor.set_framesize(width = 1920, height = 1080)
# set chn0 output format
sensor.set_pixformat(Sensor.RGB565)
# bind sensor chn0 to display layer video 1
bind_info = sensor.bind_info()
Display.bind_layer(**bind_info, layer = Display.LAYER_VIDEO1)

# use lcd as display output
Display.init(Display.ST7701, width = 800, height = 480, to_ide = True)


# sensor start run
sensor.run()

#-------这个使用pipeline，用1080可以显示视频，但是用2592就报错----#
PipeLine(rgb888p_size=[1920,1080], display_mode='hdmi')
