Abstract
A reflection removal system is capable of automatically removing from digital images reflections related to photographic illumination sources ('flash'), at the time of capture, without user intervention. In an embodiment, the reflection removal system receives a set of digital images taken at substantially the same time from a camera, where one of the image is affected by flash. The images are divided into blocks, and a threshold is determined for each block, indicating the brightest pixel value related to the content of the block. The reflection removal system compares each pixel in the flash-affected image to the corresponding threshold, and generates a digital mask based on the comparison. The reflection removal system creates a corrected image based on the digital mask, such that pixels affected by flash are modified based on corresponding pixels in the other images. In an embodiment, the corrected image is color blended.
