Abstract
A method and apparatus for removing shadows from image data is provided. The apparatus includes image capture circuitry and a graphics processor. The apparatus also includes shadow remover circuitry in communication with the image capture circuitry and the graphics processor. The shadow remover circuitry includes shadow remover location circuitry configured to identify shadow image data and shadow correction circuitry configured to selectively apply a smoothing function to the shadow image data based on a value of the shadow image data. The shadow correction circuitry is configured to select between smoothed shadow image data and a value representing an average of neighboring pixel values of non-shadow image data. A display to present an output of the shadow remover circuitry is also included.
