摘要： An image-reading device includes a document supporting base, a document-pressing member, a reading unit, a controlling unit, and a determining unit. The document-supporting base has a transparent member on which a document is placed. The document-pressing member is disposed on the document-supporting base so as to cover the transparent member. The document-pressing member is capable of opening and closing on the document-supporting base. The reading unit has a light source and capable of reading an image from the document placed on the transparent member while the light source irradiates light on the document. The controlling unit is configured to control the reading unit to execute a first scanning operation to output image signals from the image on the document while the light source is lit, and a second scanning operation to output image signals from the image on the document while the light source is not lit. The determining unit is configured to determine whether outside light has penetrated the document-supporting base based on the image signals from the second scanning operation outputted from the reading unit.

摘要： A method and system for capturing images. First, a preview image of a scene is captured. Next, an automatic determination (110) is made whether the scene is a document. When it is determined that the scene is a document, at least one cameral control (e.g., 710-740) is set to a value that is tailored for document capture (138). The scene is then captured (138) using the set camera controls. Image processing (144) that is tailored for documents is then performed on the captured scene.

摘要： 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.

摘要： An image forming apparatus includes an image reading section, an image processing section, an image forming control section, and an image forming section. The image reading section is configured to read an original document and output a band data set for one band. The image processing section is configured to compress the band data set at a first compression rate to generate a first compressed band data set, expand the first compressed band data set, and subject the expanded band data set to image processing. Thereafter, the image processing section compresses the band data set subjected to the image processing at a second compression rate to generate a second compressed band data set. When the number of second compressed band data sets reaches a printing start value, the image forming control section allows the image forming section to start forming an image based on the second compressed band data sets.

摘要： Ein Farbmessgerät umfasst einen Farbmesskanal (20,30) und eine Steuerung (C), welche aus den Messsignalen des Farbmesskanals und abgespeicherten Weisskalibrationsdaten Farbmesswerte bildet. Es weist zusätzlich Korrekturmittel auf, um die Farbmesswerte in Abhängigkeit von verschiedenen Abständen (a) und/oder Winkeln (α) zum Messobjekt zu berechnen bzw. zu korrigieren.
Durch die spezielle Messwertkorrektur ist das Farbmessgerät besonders für kontaktlose Messeinsätze mit schwankenden Abständen und Winkellagen gegenüber dem Messobjekt geeignet.
