  • Determining color at an object point from multple images providing conflicting color information
    Patent number: 9389122
    Abstract: A set of images of an object are captured from a set of lenses positioned at different angles. A common point is determined, which has a color value that differs among the images. Color at the point is mathematically expressed as a set of equations. The equations comprise a recorded color value for the point, an ambient contribution, a diffuse contribution, and a specular contribution. The ambient and diffuse contributions are set as equal across the equations. The specular contribution is determined, such as by quantifying the light sources and solving for the specular contribution using a Phong lighting model equation. True color for the point, which is based on the ambient and diffuse contribution, is determined by solving a set of simultaneous equations once the specular contribution is known. An image is created where the point has the true color as determined above.
