US 8,948,508 B2 · System and method of adaptive color correction for pill recognition in digital images

Abstract

A system and method for correcting colors in an image in order to identify pills. The system includes a surface that includes a background upon which pills are positioned and a border of known color adjacent to the background. The system also includes a digital camera and a processor. The processor is used to receive and process the image, use target objects on the surface to identify areas of the image that correspond to the known characteristics and features of the surface, perform image diagnostics to determine if the image can be used, and correct image color based on comparison of identified areas of the image that correspond with the known characteristics and features of the surface. Various graphical displays or cues can assist a user in obtaining a usable image.

A method of correcting colors in an image, the method comprising:

using a digital camera and a surface to obtain a digital image representing one or more pills on the surface, the surface including a background upon which the one or more pills are positioned, a border extending around the background, and a plurality of target objects;
identifying areas of the image that correspond to areas of the surface with known colors and features;
performing image diagnostics on the image to identify imaging conditions adverse to color-correction;
and
if image diagnostic results are acceptable, correcting color in the image based on a comparison of image colors with corresponding surface areas with known colors.
