Abstract
A digital camera has an integral flash and stores and displays a digital image. Under certain conditions, a flash photograph taken with the camera may result in a red-eye phenomenon due to a reflection within an eye of a subject of the photograph. The digital camera has a red-eye filter which analyzes the stored image for the red-eye phenomenon and modifies the stored image to eliminate the red-eye phenomenon by changing the red area to black. The modification of the image is enabled when a photograph is taken under conditions indicative of the red-eye phenomenon. The modification is subject to anti-falsing analysis which further examines the area around the red-eye area for indicia of the eye of the subject.
Claims18
Within a portable digital camera having no photographic film, a method of filtering a red-eye phenomenon from a digital image comprising a multiplicity of pixels indicative of color, the pixels forming various shapes of the image, the method comprising the steps of:
- locating pixels having a color indicative of the red-eye phenomenon;
- determining if a grouping of at least a portion of the pixels of said step locating comprise a shape indicative of the red-eye phenomenon;
- modifying the color of the grouping in response to said step of determining;
- and
- analyzing if conditions of recording of the image are indicative of the red-eye phenomenon, wherein said step of modifying is selectively performed in response thereto.
A portable digital camera having no photographic film comprising:
- an integral flash for providing illumination during image recording;
- a digital image capturing apparatus for recording an image;
- and
- a red-eye filter for modifying an area within the image indicative of a red-eye phenomenon.
