Abstract
A light source irradiates one side of a transparent container and a video camera is placed to pick up the image of the transparent container so that it will not directly receive the reflection of light from the light source. A nonreflecting plate is placed behind the container in opposition to the video camera. An image processor processes the output image of the camera. A light diffusion plate may be placed in front of the light source.
