    摘要: A method and apparatus for detecting surface defects and artifacts on a transmissive image in an optical image scanner and correcting the resulting scanned image. In one scan, the image is scanned normally. Surface defects and artifacts such as dust, scratches and finger prints are detected by providing a separate scan using infrared light or by measuring light (white or infrared) that is scattered or diffracted by the defects and artifacts. Separate optical paths for illumination may be used, or separate optical paths for intensity measurement may be used. Image processing may then be used to correct areas in the normal scan corresponding to defects identified in the separate scan.

    摘要: In an embodiment, a method sets an image capture device to one of a plurality of available operational modes for the image capture device. The method comprises determining an angle of pitch orientation of the image capture device, and setting the image capture device to the one of the plurality of operational modes if the angle of pitch orientation is within a predetermined angle range associated with the one of the plurality of operational modes.

    摘要: Systems and methods for implementing Z-buffer generation in a camera are disclosed. In an exemplary embodiment the method may comprise exposing a plurality of pixels on an image capture device to a modulated light signal reflected from different regions of a scene adjacent a camera after different delays. The method may also comprise correlating intensity of the modulated light signal received by the image capture device for each the different delays to determine a flight time of the modulated light signal. The method may also comprise generating a Z-buffer corresponding to the different regions of the scene based on the correlation.

    摘要: A digital camera simulates the use of fill flash. The camera takes a series of photographs of a scene at various focus distances. The photographs are stored, along with their corresponding focus distances. The photographs are analyzed to determine the distance to objects at various locations of the scene. Regions of a final photograph are selectively adjusted in brightness based on the distance information to simulate the effect that would have resulted had fill flash been used.
