说明：  我修改了Shiqi Yu编写的CCameraDS类,增加ShowPinPropertyPage,ShowFilterPropertyPage,GetDeviceFilter,GetCameraOutput四个函数 在CB2007下通过编译 不知为何,修改Camera属性后,有时不会取到图像回来,特别是修改图像大小
(I modified the Shiqi Yu CCameraDS class prepared to increase ShowPinPropertyPage, ShowFilterPropertyPage, GetDeviceFilter, GetCameraOutput through the four functions in the CB2007 compiler do not know why, modify Camera properties, sometimes does not get the image back, especially to modify the image size)
