Method of acquiring an image in a transparent, colored container
First Claim
1. A method of acquiring an image of objects within a transparent, colored container, comprising:
- detecting RGB values of a color of the container;
based on the detecting step, automatically determining inverse RGB values of the color of the container;
illuminating the container and the objects therein with light having substantially the inverse RGB values of the color of the container; and
acquiring the image of the objects within the container.

Abstract
A vision system useful in acquiring images includes: a light dome having a window and a perimeter; an annular light curtain positioned within and radially inwardly from the perimeter of the light dome such that an annular gap is formed between the light dome and the light curtain; and a light ring positioned to illuminate the gap between the light dome and the light curtain. The light curtain and window are sized and positioned such that no direct light from the light ring reaches the window. The system further comprises a camera having a lens facing the window to acquire images of an object on a side of the window opposite the camera. The images acquired by the camera can then be compared to stored images to determine whether the identity of the objects (which may be pharmaceutical tablets) is as expected.
