Red-eye filter method and apparatus using pre-acquisition information |
摘要 |
A digital image acquisition system having no photographic film, such as a digital camera, has a flash unit for providing illumination during image capture and red-eye filter for detecting a region within a captured image indicative of a red-eye phenomenon, the detection being based upon a comparison of the captured image and a reference image of nominally the same scene taken without flash. In the embodiment the reference image is a preview image of lower pixel resolution than the captured image, the filter matching the pixel resolutions of the captured and reference images by up-sampling the review image and/or sub-sampling the captured image. The filter also aligns at least portions of the captured image and reference image prior to comparison to allow for, e.g. movement in the subject. <Figure 1> |
