Abstract: A duplex scanner capable of calibrating the two-sided documents comprises an automatic document feeder (ADF), an upper carriage and an upper calibration paper. The upper carriage is installed in the ADF and the upper calibration paper is installed under the upper carriage. Alternatively, the upper carriage is movable installed in the ADF while the upper calibration paper is fixed in the duplex scanner and corresponding to the upper carriage. Before image scanning, the relative motion between the upper carriage and the first calibration paper is generated for calibrating the light beam information.

Abstract: A linear pixel-array processing systems uses a combination of digital and analog signal processing techniques to calibrate the gain and offset of each pixel in the analog domain. A plurality of fixed gain and offset values are applied in the analog domain to adjust the gain and offset of each pixel at high speeds (on the order of 25–50 MHz). By adjusting the gain and offset in the analog domain, the dynamic range of pixel conversion is improved such that the conversion range is fully utilized (over 90%, on the order of 95%–99%). The gain and offset values are determined with an algorithmic calibration routine that corrects for non-ideal effects in the signal path. A single processing channel can be multiplexed to process multiple pixel arrays to provide for a cost effective solution. In higher speed systems, the single processing channel can be extended to multiple processing channels for improved throughput.

Abstract: At a conventional image scanning method, it takes long time to transfer an image data of whole image, consequently it takes long time to display the whole image on a display. Therefore, an image scanning method and an apparatus thereof, with which a user can recognize mistakes at reading a document at earlier time, are provided. By one time scanning, an image data whose resolution is lower than fundamental resolution is read. The image data of lower resolution is obtained by that the image data are thinned out. And this image data having lower resolution is displayed on a display as a preview image. By rescanning, an image whose resolution is higher than the preview image is read and displayed. This preview image can be displayed in short time, therefore the user can recognize a mistake at earlier time.

Abstract: The image reading device has a reading operation control processor that automatically starts a reading operation. In the reading operation, first, it is determined whether a film is attached to the image reading device. When the film is not attached to the image reading device, the reading operation is not proceeded. Conversely, when the film is attached to the image reading device, a pre-scanning operation is performed in which an image recorded in a film is read with a relatively coarse pitch, after a waiting time has passed. Then, a regular scanning operation is performed in which the image is read with a pitch finer than that of the pre-scanning operation.

Abstract: A compression and decompression system and process for optimally compressing and decompressing multibit per pixel image regions based on the type of data contained in the image region, e.g., whether the image region contains continuous tone data, including data to be halftoned, or non-continuous tone data, including antialiased text and lineart data. Segmented bytemap data blocks are processed to provide both low spatial resolution continuous tone data and high spatial resolution non-continuous tone data. However, the high spatial resolution non-continuous tone data is generated by quantizing and packing the high resolution bytes across an edge and discarding the high resolution bytes along the edge, i.e., the multibit data is discarded only in directions parallel to the edges of marks to be rendered in the image data. Additional information indicating the directions of the edges in the image data are stored to aid in decompression.

Abstract: An image reading device is provided in which processing of magnetic information and image reading can be carried out efficiently, and parts can be arranged highly efficiently in terms of space. By conveying an APS film in a pull-out direction, magnetic information is read by a magnetic head, and an image frame is prescanned by a line CCD. Next, the APS film is conveyed in a take-up direction, and fine scanning is carried out by the line CCD and magnetic information is written by a magnetic head. In this way, because writing of magnetic information can be carried out during conveying for fine scanning, processing time can be shortened. Moreover, because a distance between the magnetic head and the line CCD is not restricted, the magnetic head and the line CCD can be disposed at positions which are efficient in terms of space.

The record includes dimensions of one or more visible features of an item corresponding to the machine readable information and identified according to their location relative to the machine readable information. These dimensions of features are then compared to the dimensions of features of the item being scanned to determine whether the machine readable information read by the scanner matches the item being scanned.

Abstract: An image alignment method and system for aligning two digital images which were intended to be scanned from the same portion of medium, but which may be skewed somewhat. A portion of the first digital image is selected as the target region and a portion of the second digital image is selected as a variable or movable region. Data from the two regions can be subjected to a mathematical or statistical algorithm which determines how well the data from the regions match or correlate. Then, a new region can be selected to serve as the variable region from the second digital image and the correlation algorithm can be conducted again. This process can be repeated on a number of regions from the second digital image. Regions having the highest mathematical correlation can then be used to determine offsets which indicate the amount of skew or misalignment between the two digital images.

Abstract: An image reading apparatus includes a plurality of reading sections (CCD elements) and reads a photographic photosensitive material by pre-set plural reading sections of the plurality of reading sections. In the image reading apparatus, on the basis of a value indicating an amount of deviation between an actual reading position and a predetermined proper reading position, the plural reading sections which read the photographic photosensitive material are suitably shifted from pre-set plural reading sections.

Next, a proper imaging position H0, at which the reference position of the photographic photosensitive material should be imaged on the reading device, is fetched.

Abstract: Surface defect correction technology for photographic images requires an infrared scan along with a conventional color scan. In the present invention, the additional infrared scan needed for surface defect correction is obtained by adding a line of sensors specific to infrared light to a conventional multilinear color sensor array. The invention teaches a practical mode of distinguishing infrared light using a dichroic prism placed over the sensor. This mode has the additional advantage of placing the infrared-specific sensor line in a displaced focus plane to match conventional lenses. Adding a sensor line to a conventional trilinear sensor array requires a quadrilinear array topology.
