    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: A digital camera takes interleaved photographs of two different kinds. In one example embodiment, the first kind of photograph is taken using a first set of pixels of the camera's electronic array light sensor and has a short exposure time. The second kind of photograph is taken using a second set of pixels and has a long exposure time. More than one of the short-exposure-time photographs is taken while each long-exposure-time photograph is exposed. The two kinds of photographs are used for different purposes. For example, one kind may be used for performing automatic focusing while the other kind is used for displaying in a live view display. In this way, live view may continue while automatic focusing is performed. In another embodiment, one kind of photograph is used for providing a live view display, and the other is used in selecting exposure settings for a final photograph.

    摘要: A system and method for generating multiple processed images from a single captured image generated by an electronic imaging device. In one embodiment, a digital camera includes multiple sets of operating parameters which may be advantageously configured according to the demands of particular photographic environments. For each image captured by a digital camera as raw data, the data is processed according to each parameter set prior to compression, storage in temporary memory, and ultimate upload onto a computer or other permanent storage device.

    摘要: An apparatus and method of processing images in a digital camera and improving the quality of images produced by camera processing software. In low-light digital camera photography, a dark frame image is subtracted from an original picture image to form a resulting image. The resulting image formed from the dark frame subtraction is evaluated for negative and invalid pixel values. Each negative and invalid pixel value is replaced using a pixel replacement algorithm with appropriate positive values.

    摘要: A reflector (R) having an improved neck section that increases the useful light output of the lamp is disclosed. The reflector lamp comprises a concave reflector having a primary reflective surface with a parabolic shape, one or more intermediate reflective surfaces with a parabolic shape substantially confocal with the primary reflective surface, and an improved neck section comprising a reducing section, a first substantially straight cylindrical section, an expanding section and a second substantially straight cylindrical section.
