Irradiate the entire side of Comfort Food 11. 14trJ, half mirror placed slightly in front of the test food, half mirror 14'? O16 is a camera that irradiates the object to be inspected through f, and on the upper part of this camera, a half mirror 14 is used to irradiate the object to be inspected. reflect,
Above the camera m+vtl and f? The 5-ray illumination method uses a silhouette method that captures a silhouette image from the side, and processes the shape of the image as a black and white image.
The image is processed in step 17 and displayed on a monitor television 18.

As shown in Figure 3, the screen on the monitor TV is divided into two screens, with half showing the top image and the top half showing the side image.Masks are created in the necessary areas, and the inside of the screen is inspected. In addition, the top image and the side image (black and white are reversed).The present invention is arranged diagonally above C5 behind the food to be tested via a diffusion filter R, and then the image above the food to be tested is slightly exposed. The light W that irradiates the test food gold is placed in front of the 7ζ half-mirror, and the top and side images of the test food are simultaneously captured using the half-mirror valve. The camera is configured as a binarized image, with a top-view image in the upper half, a side curved surface 1'lj in the upper half, and a monitor TV for k-photographing. (If half mirror?!- The combination of the epi-illumination method and the silhouette method used simplifies the arrangement of the light monuments and reduces mutual interference between the light sources.
