A scanning device reads image data, stores the image data in a unit of raster in a buffer and transferring the image data to a host computer. The scanning device has a stop unit to temporarily stop reading the image data when an empty capacity of the buffer becomes smaller than a predetermined amount, a write unit to write specified mark data in a next storage line of raster image data lastly read and stored in the buffer in response to a temporary stop, and a restart unit to restart reading the image data by overlapping the raster image data lastly read when the empty capacity of the buffer becomes larger than the predetermined amount.

An image read processing device connected to a scanner reading an image of a document comprises at least a memory and a controller. The memory comprises a setting information recording unit that records a setting information with an application to start up depending on a document size defined there. The controller comprises a scanner controlling unit that controls the scanner, a document size checking unit that checks the document size of the image read out by the scanner according to the control of the scanner controlling unit, and a start-up application determining unit that determines the application depending on the document size checked by the document size checking unit, based on the setting information recorded in the setting information recording unit and starts up the application.

There are provided an image processing apparatus, line detection method and a computer-readable, non-transitory medium that can precisely detect boundaries of a document from a read image. The image processing apparatus includes an edge pixel extractor for extracting edge pixels from an input image which includes a document, a grouping unit for forming mutually adjoining edge pixels in the extracted edge pixels into a group, and an approximated line detector for detecting a line which connects edge pixels which are positioned at the two ends in a horizontal direction and vertical direction among edge pixels which are included in the group as a line which approximates an end of the document.

In an image sensor, light sources corresponding to each of R, G, B colors illuminate multiple times in each line cycle so that each of line sensors acquires multiple R, G, B signals in each line cycle. A controlling unit generates multiple R, G, B data in each line cycle from the multiple R, G, B signals, and adds the multiple R, G, B data in each line cycle in a corresponding one of data saving units.

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 scanning apparatus includes a scanning unit that scans an image from an image display medium optically and creates image data; a data comparison unit that compares the image data scanned by the scanning unit and image data recorded in a predetermined recording region; and a notification unit that notifies an operator depending on a result of comparison by the data comparison unit.

An image-data-acquisition control unit controls an image-data acquiring unit that acquires computer-recognizable image data, to accumulate the image data in a set of information units. A character-recognition control unit controls an optical character-recognizing unit that extracts a character from the set of image data accumulated by the image-data-acquisition control unit, to accumulate a group of characters obtained by the optical character-recognizing unit in a set of character information units. Once a start signal is received from a starting unit, the image-data-acquisition control unit and the character-recognition control unit continue to operate independently.
