A scanning device includes a first scanning unit having a first line sensor and a first light source that emits a first light beam and is arranged only at one side of the first scanning unit in a main scanning direction, and a second scanning unit having a second line sensor and a second light source that emits a second light beam and is arranged only at one side of the second scanning unit in the main scanning direction. The first scanning unit and the second scanning unit face each other and are disposed such that the first light source and the second light source are arranged at the same side of the main scanning direction, and centers of the first line sensor and the second line sensor are located at the same position in the main scanning direction.

Scanning device, apparatus and method for image processing

A scanning device includes a first scanning unit having a first scanning element array to scan a first surface of a scan-target medium to acquire a first image, a second scanning unit having a second scanning element array to scan a second surface of the scan-target medium to acquire a second image, and an output unit that outputs a first image signal of the first image and a second image signal of the second image. The first scanning unit and the second scanning unit face each other to scan the first surface and the second surface concurrently. When the scanning directions of the first scanning element array and the second scanning element array are the same, a mirrored image acquired from one of the first image signal and the second image signal is inverted so that the output unit outputs normal images of the first surface and the second surface.

An image processing method executed by an image processor comprising a displaying unit, a storage unit, and a control unit, wherein the storage unit includes an image data storage unit that stores image data displayed in thumbnail form and a keyword associated with the image data, and the method includes a keyword obtaining step of obtaining the keyword corresponding to the image data stored in the image data storage unit; and a thumbnail image with keyword displaying step of displaying the keyword obtained at the keyword obtaining step on the displaying unit, with the keyword being overlapped with the image data.

Image processor and image processing method

An image file sorting method is executed by an image file sorting device, including a storage unit, a control unit, and an image reading unit, wherein the storage unit includes a sorting condition storage unit that stores a sorting condition to specify a sorting destination of an image file. The method includes a sorting keyword extracting step of extracting a sorting keyword from a marker portion of the image file read by the image reading unit, a sorting destination deciding step of deciding the sorting destination of the image file by collating the sorting keyword extracted by the sorting keyword extracting step and the sorting condition stored in the storing condition storage unit, and an image file sorting step of sorting the image file into the sorting destination decided by the sorting destination deciding step.

An image processor comprising a control unit, wherein the control unit includes an obtaining unit that obtains image data generated as a result of reading a document by a reader in which a predetermined document reading condition is set; a selecting unit that allows a user to select an use of the image data obtained by the obtaining unit out of a plurality of the uses set in advance; a processing unit that processes the image data obtained by the obtaining unit according to an image processing condition suitable for the use selected by the selecting unit; and a transferring unit that transfers the image data after being processed by the processing unit to an application suitable for the use selected by the selecting unit.

Image processor, image processing method, and computer program product

A power supply controlling circuit includes: power supplied portions, adapted to receive power supply from at least one external apparatus; a first power unit, adapted to be driven by a first power; and a second power unit, adapted to be driven by a second power. In response to a change of the power supply, the second power is varied, while the first power is maintained.

Power supply controlling circuit and scanner unit

An image sensor includes a line sensor having sensor elements arranged in one line and configured to acquire, in each line cycle, R, G and B signals, when light sources, each corresponding to one of R, G and B colors, in the each line cycle, sequentially illuminate one after another in a predetermined order; a buffer having data saving units, each corresponding to one of the R, G and B colors; a controlling unit configured to generate, from the R, G and B signals, R, G and B data in each line cycle, and to add each of the R, G and B data in each cycle in a corresponding one of the data saving units; and an output unit configured to output to outside, as RGB line data, the R, G and B data in each line cycle that have been saved in the data saving units.

Image sensor, image sensor unit, and image reader

An image reading apparatus includes pairs of rollers, each including a driving roller and a driven roller. The pairs of rollers are arranged along the rotation axis direction of the driving roller and constitute a first roller group and a second roller group for conveying a first medium and a second medium thicker than the first medium, respectively. The center of the first roller group is identical in the rotation axis direction to that of a first conveying area where the first medium is conveyed. The center of the second roller group is identical in the rotation axis direction to that of a second conveying area where the second medium is conveyed. At least one pair of rollers in the second roller group is arranged outside the first roller group within the first conveying area.

Image reading apparatus

An image reading apparatus includes light sources, an image sensor, a data generating unit, and a carrier unit. The light sources are sequentially turned on for an identical period once in a single line period. The image sensor reads information from a print medium irradiated by the light sources. The data generating unit generates pixel data corresponding to the information. The carrier unit carries the print medium such that the image print medium is scanned by the image sensor in a sub-scanning direction. The single line period is equal to or more than twice a period from when first one of the light sources is turned on until last one of the light sources is turned off.

Image reading apparatus and controlling method thereof

After reading a predetermined number of predetermined blocks for each of a plurality of image data, a first image read unitreads out the plurality of image data read in parallel by repeatedly switching the designated order of the plurality of image data. A JPEG compression unitperforms image compression on the plurality of image data read out in block units by the first image read unit, image-compresses a predetermined number of the blocks for each of the plurality of image data, and then inserts an identifier after the last block of the predetermined number of blocks.
