Abstract: PROBLEM TO BE SOLVED: To detect a prescribed pattern rapidly and reliably using an image reader.
SOLUTION: The image reader comprises: a reading section; a control section; and a pattern region including a prescribed pattern. The control section includes: a first image acquisition section for acquiring first image data; a pattern searching section for searching a prescribed pattern in the first image data; a second image acquisition section for acquiring second image data when no prescribed pattern is detected; a characteristic part searching section for searching a characteristic part in the second image data; a first reprocessing instruction section for specifying a position of a pattern region based on a position of the characteristic part when the characteristic part is detected for rereading by the first image acquisition section; and a second reprocessing instruction section for allowing the second image acquisition section to perform rereading at a position without including positions where the characteristic part is detected, when no pattern is detected again in the first image data generated by rereading by the first image acquisition section.

Abstract: A scanning device and an image forming device including the same are provided to differently control a moving speed for moving a scanning head to a home position according to the position of the scanning head. A position recognizer(21) is formed on a stage glass(20) along a moving direction of the scanning head(30). A head position recognizer(35) recognizes the position of the scanning head by recognizing the position of the position recognizer when a scanning signal is received. A controller(70) enables the scanning head to move to the home position at the faster speed than a reference speed if the recognized position of the scanning head is separated from the home position over a predetermined distance. The position recognizer includes a position recognition mark formed by at least one of a character or a number recognizable to the scanning head. The stage glass includes an actual scanning area and an effective scanning area corresponding to both ends of a scanning sensor. The position recognizer is installed to the effective scanning area.

Abstract: A scanner which converts an oversampled substrate image into a digital pixel array which may be at an arbitrary sampling frequency lower than the first sampling frequency. The scanner sensor converts the substrate image into an array of analog pixel at a first sampling frequency. Preferably the first sampling frequency substantially oversamples the image from the actual frequency desired in the final digital image. The analog pixels are converted into a first array of digital pixels. The first digital pixel array is converted by a sinc filter in the linear lumen domain, i.e. the digital pixels are linearly representative of the brightness of light sensed by the sensor, to a second array of pixels at a second sampling frequency. The second sampling frequency should be much lower than the first sampling frequency to produce high quality images with substantially fewer pixels than required by the prior art.

Abstract: 記録ヘッド（１６）は、記録媒体（１７）に画像スワスの規則的なパターンを形成する。 画像フィーチャーの規則的なパターンは、第１の所定値に設定されたイメージングパラメータを有して形成される第１の組の画像フィーチャー（６０Ａ）と、第１の所定値とは異なる第２の所定値に設定されたイメージングパラメータを有して形成される第２の組の画像フィーチャー（６０Ｂ）とを有する。 第１の組及び第２の組における画像フィーチャーは、画像スワスの副走査空間周波数の非整数倍に等しい副走査空間周波数を有して記録媒体に配置される。 スキャナ（４０）は走査パターンのデータ（４７）を生成し、スキャナによって用いられるサンプリング空間周波数の第１の整数倍は、第１の組及び第２の組の画像フィーチャーの副走査空間周波数の第２の整数倍に等しい。 データは、第１の組及び第２の組の間のバンディングを表す定量値を決定するよう分析され、この定量値に基づきイメージングパラメータは調整される。

Abstract: An image reading apparatus includes a reading unit, a control unit, and a pattern region. The reading unit moves a linear reading range, which is provided in a main scanning direction, in a sub-scanning direction that intersects with the main scanning direction while reading an object that faces the reading range, and generates image data on the basis of a read result. The control unit controls the reading unit. The pattern region includes a predetermined pattern that defines a reference position for specifying a reading position that is read by the reading unit. The predetermined pattern has a characteristic portion that specifies a schematic position of the predetermined pattern in the sub-scanning direction. The control unit includes a first image acquisition unit, a pattern searching unit, a second image acquisition unit, a characteristic portion searching unit, a first reprocessing instruction unit, and a second reprocessing instruction unit. The first image acquisition unit instructs the reading unit to perform reading and then acquires first image data. The pattern searching unit searches an image of the predetermined pattern in the first image data. The second image acquisition unit, when an image of the predetermined pattern has not been detected by the pattern searching unit, instructs the reading unit to perform reading, and then acquires second image data. The characteristic portion searching unit searches an image of the characteristic portion in the second image data. The first reprocessing instruction unit, when the image of the characteristic portion has been detected by the characteristic portion searching unit, specifies a schematic position of the pattern region in the sub-scanning direction on the basis of a position of the detected image of the characteristic portion, and instructs the first image acquisition unit to perform reading again at the schematic position of the pattern region. The second reprocessing instruction unit, when the image of the predetermined pattern has not been detected again from first image data that are generated through second-time reading by the first image acquisition unit, instructs the second image acquisition unit to perform reading again at a position that does not include the position at which the image of the characteristic portion has been detected.
