Integrated currency validator
First Claim
1. A currency validator, comprising:
- a currency counter receiving a plurality of currencies including a test currency, the currency counter counting the currencies;
a plurality of cameras, each camera being located at a different angle from an area on the test currency, the cameras outputting a plurality of images of the area;
an image processing unit receiving the images from the cameras, the image processor outputting a plurality of processed images;
an image comparing unit receiving the processed images, the comparing processor outputting a plurality of error matrices based on differences between characteristics of the processed images and characteristics of corresponding reference images; and
a threshold analysis unit receiving the error matrices, the threshold processor outputting a validation result based on comparisons of the error matrices and corresponding threshold matrices.

Abstract
A currency validator includes a currency counter, a plurality of cameras, an image processor, a comparing processor, and a threshold processor. The currency counter counts multiple currencies including a test currency. Each of the cameras is located at a unique angle from a characteristic area on the test currency. The cameras record and output multiple images of the characteristic area. The image processor crops and reduces the recorded images. The comparing processor compares the processed images with corresponding references. The comparing processor then outputs the results as error matrices. The threshold processor compares the error matrices with corresponding threshold matrices. The threshold processor then outputs a validation result for the tested currency based on the comparison.
