An image processing apparatus includes a processing unit that converts first input image data for a first region and second input image data for a second region to reduce a difference between first region recorded image density and second region recorded image density, and generates dot position data of a dot to be generated in each of the first and second regions based on the dot data after the conversion processing. The acquisition unit acquires edge information indicating a first object pixel edge of an image pixel for the first region and a second object pixel edge of an image pixel for the second region. Based on the acquired edge information, conversion and generation processing are performed in such a manner that a color signal of an edge pixel is increased/reduced to a degree lower than a degree to which a color signal of a non-edge object pixel is increased/reduced.

A document camera system includes a page-turning device, an image pickup unit, a specification unit, a recognition unit, a determination unit and a notification unit. The page-turning device turns pages of a book. The image pickup unit picks up an image of each turned page. The specification unit specifies a page number portion in the image picked up by the image pickup unit. The recognition unit recognizes characters in the page number portion specified by the specification unit to identify a page number. The determination unit determines correctness of the order of the page numbers identified by the recognition unit. The notification unit notifies a user of an error when the determination unit determines that the order of the page numbers is incorrect.

A fraud confirmation assisting apparatus includes a light source, a reading sensor, and processing circuitry. The light source irradiates an object to be read with light in at least an invisible wavelength range. The reading sensor has sensitivity at least in the invisible wavelength range. The processing circuitry performs a reading operation on the object to be read by a combination of the light source and the reading sensor, and outputs a plurality of pieces of fraud confirmation information based on read information output from the reading sensor by the reading operation.

A multimedia device 2 is proposed having a display unit 6 for displaying at least one optical code 5, wherein the optical code 5 is configured to be acquired by a read device 3, wherein the multimedia device 2 comprises a coding unit 4, wherein the coding unit 4 is configured to code operating data of the multimedia device 2 as the optical code 5.

There is disclosed an apparatus and method of aligning content put through a duplex scanner. By performing operations on data extracted from physical documents, digital documents that would otherwise appear skewed can be un-skewed. The process compares two images, e.g. a front and a back page for a document, and determines how they are offset from one another. The process uses a projection profile error minimization technique to calculate a translation for one or both pages to digitally align the margins for a digital document such that the margins match.

An imaging device includes a light source unit located so as to be inclined with respect to a medium conveying surface or a medium placing surface. The light source unit includes a light emitting element, a light guide provided with the light emitting element on a first end surface side, to guide light emitted from the light emitting element in a predetermined direction, and emit the light toward the medium from an emitting surface extending in the predetermined direction, and a reflector located around the light guide other than the emitting surface. The light guide includes a light diffusing surface on an opposite side to the emitting surface. The reflector does not cover a second end surface opposite to the first end surface of the light guide. A medium side surface of the reflector is located so as to protrude from the second end surface of the light guide.

Selecting objects in a video stream of a smart phone includes detecting quiescence of frame content in the video stream, detecting objects in a scene corresponding to the frame content, presenting at least one of the objects to a user of the smart phone, and selecting at least one of the objects in a group of objects in response to input by the user. Detecting quiescence of frame content in the video stream may include using motion sensors in the smart phone to determine an amount of movement of the smart phone. Detecting quiescence of frame content in the video stream may include detecting changes in view angles and distances of the smart phone with respect to the scene. Detecting objects in a scene may use heuristics, custom user preferences, and/or specifics of scene layout. At least one of the objects may be a person or a document.

An image reading device includes a placement section on which a subject is placed, an image capturing unit that is disposed above the placement section and captures an image of the subject, an irradiating unit that is disposed above the placement section and irradiates the subject with light, and a display unit that is disposed between the placement section and the image capturing unit and between the placement section and the irradiating unit, the display unit being located at a position outside an image capturing range of the image capturing unit and an irradiation range of the irradiating unit.
