Abstract: When an optical image obtained by an optical scanning unit of optically scanning an original sheet automatically fed by an original sheet feeder is read, it is discriminated in units of pixel whether or not dirt or scratch attached to a running reading glass plate is present. Moreover, the number of the dirt and the width of the dirt are detected, and an image reading position which does not come under the influence of the dirt as much as possible is set based on the detected number of the dirt and the detected width of the dirt even when the dirt is detected at all the reading positions.

Abstract: Facsimile scanning apparatus is provided with two carriages which move in antiphase with one another along parallel rails and respectively scan alternate lines. The two carriages are interconnected by a tensioned inextensible loop passing around a pulley at one end of the rails. The pulley is movable towards and away from the rails so that the phase relationship of the carriages may be adjusted while the apparatus is in use, thus ensuring that the desired 180* antiphase relationship necessary for good facsimile reproduction can be attained quickly and easily.

Abstract: In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.

Abstract: Systems and methods using an orientation/position-sensitive calibration pattern for three-dimensional calibration of an imaging system, such as one used in a process for scanning documents are disclosed. The method generally includes positioning the pattern on a support, capturing images using cameras to be calibrated, each image containing at least a unique orientation and position sensitive sub-area of the pattern, determining a set of coordinate pairs of corresponding points in the image and the pattern for each image utilizing image data and pattern information, and performing optimization utilizing the sets of coordinate pairs to calibrate relative position, orientation, zoom, and/or lens distortion, etc. of each camera so as to construct a three-dimensional camera calibration model. The pattern is generally comprised of overlapping sub-areas of a minimum portion of the pattern.

Abstract: An image capturing system has a digital camera and a supporting stand which can move the digital camera in parallel with the surface of a placed original (subject). In the image capturing system, an image of a subject is captured. In the case where reflection from a room lighting device occurs in an area in a captured image, the digital camera is moved in parallel by using the supporting stand and captures an image again. Consequently, the position where the reflection occurs is changed in an image capturing range, so that the reflection does not occur in an area in a captured image of the subject corresponding to the area in which the reflection occurs. When the image part of the area where the reflection occurs is replaced with the image part of the area, an image from which the reflection is removed is obtained. As a result, reflection in an image can be easily and promptly removed.
