Abstract: Image data in an image scanner is examined to determine whether lines (light or dark) are present in the image data. By examining whether the lines are present in image data for multiple colors, and whether calibration gains for corresponding photosensors are normal, it can be determined whether the lines & likely caused by a surface defect, on a calibration target, or on a platen, or on an image being scanned.

Abstract: A method, for use on a computer system having a memory, permits a user to index and track digitized images resident in said computer memory. The method comprises creating a scannable contact sheet comprising thumbnail versions of the digitized images, information identifying each image, and at least one instruction for a corresponding designated image, the at least one instruction being manually selectable by the user, and printing out the contact sheet. Also disclosed is a computer system enabling a user to index and track digitized images resident in a memory accessible by the computer system. The computer system comprises (1) means for creating a scannable contact sheet, the contact sheet comprising thumbnail versions of the digitized images, information identifying each image, and at least one instruction for each image, the at least one instruction being manually selectable by the user; and (2) means for printing out the contact sheet.

Abstract: Multiple scans of the same object are obtained, where for any given line on the object to be scanned, the angle of the illumination is different for each scan. The different scans are obtained from different rows of photosensors that are separated. Because the angles of illumination are different, the resulting shadows in each scan are different. The multiple scans may be combined into a single composite color image. In a composite image, a dust particle may generate a series of overlapping shadows, where each shadow is a different color. Searching the composite image for the unique pattern of colors may identify artifacts or defects. Alternatively, the data for one scanned image may be compared to the data for another scanned image, and any differences may be due to shadows, which may indicate defects.

Abstract: The present invention provides a system and method for capturing images. Briefly described, one embodiment comprises a digital camera, the digital camera comprising at least a photosensor; and an enclosure configured to receive the digital camera, configured to have at least one feature controlling operation of the digital camera, and configured to capture an image using the photosensor of the digital camera.
