Abstract: An image reading apparatus includes a document sheet table, an image reading portion, a detection processing portion, and a determination processing portion. A document sheet is placed on the document sheet table. The image reading portion reads linear image data representing an image of a linear area that extends along a main scanning direction of the document sheet that is placed on the document sheet table. The detection processing portion detects, based on the linear image data, a size of the document sheet in the main scanning direction. The determination processing portion determines, when the size of the document sheet in the main scanning direction detected by the detection processing portion meets a specific condition, that the document sheet is a predetermined card-shaped document sheet.

Abstract: A document feed portion of an image reading device is capable of feeding a document placed on a first document placement portion, to a predetermined reading position. A size detection portion detects a size of the document placed on the first document placement portion. A storage processing portion stores size information indicating the size of the document detected by the size detection portion, into a predetermined storage medium. An image reading portion performs a reading process of scanning a read surface of the document placed on a second document placement portion, to read an image. A setting portion sets the size information stored into the storage medium by the storage processing portion, as size information to be used for the reading process by the image reading portion.

Abstract: This image processing apparatus identifies the orientation of a document image in a horizontally written text document. The image processing apparatus includes a character identification unit, a line identification unit, and an orientation identification unit. The character identification unit identifies a character bounding rectangle for every character in the document image based on extracted edges. The line identification unit merges the character bounding rectangles identified by the character identification unit to identify a plurality of line bounding rectangles. The orientation identification unit identifies the positions of a short side on one end and a short side on the other end, in the longitudinal direction, of each of the line bounding rectangles identified by the line identification unit to identify the orientation of the document image based on the positional distributions of the identified short sides of the line bounding rectangles.

Abstract: An image processing apparatus includes a document feeding unit, a document reading unit, a first set-document direction accepting key, an automatic determination mode setting accepting key, a set-document direction determining unit, and an image processor. The set-document direction determining unit is configured to determine, on a per-page basis, a set-document direction of documents set on the document feeding unit, based on original image data read by the document reading unit. The image processor is configured to perform a rotation process on original image data read by the document reading unit, based on the determination result by the set-document direction determining unit, and to perform a rotation process based on the first set-document direction accepted by the first set-document direction accepting key for a page for which the determination by the set document direction determining unit fails.

Abstract: An edge image generating unit generates an edge image formed by edges in an original image. A connection pixel extracting unit extracts connection pixel sets in the edge image. A binary image generating unit classifies the connection pixel sets by colors and generates respective character images of the colors. A background image generating unit generates a background image of the original image. An image compressing unit compresses image data of the character images and the background image using different compressing methods. The binary image generating unit identifies which of a density reversed character, an ordinary character and non character each one of the connection pixel sets is, on the basis of luminance values of the original image on pixels at four corners of a rectangle circumscribed to the connection pixel set, and generates the character images of the density reversed character and the ordinary character.
