    摘要: Provided is a target location determination device that is able to accurately recognize a color pattern as well as reducing the calculation load, even when using a color camera and a color target. The target location determination device is provided with a grayscaling profile storage portion that stores a grayscaling profile according to which the luminance difference between a first monochrome color converted from a first color and a second monochrome color converted from a second color of a target is greater than the luminance difference between the first color and the second color, and a grayscaling portion that converts color image data into grayscale image data using the grayscaling profile.

    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 a 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 preview 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.
