Abstract

A method for measuring color of objects comprises storing in a computer memory values representative of measurements of the color of an object over a range of angular positions with respect to a photosensor, selecting a measurement area of the object, determining a geometrical structure of the measurement area, and adjusting the measured color in response to the stored values. An associated apparatus is also provided.
