A device for registration of content in a filled-out application form is disclosed. The device is configured for scanning at least one portion of the filled-out application form. The device is configured for extracting filled-out content from the scanned form. The geometrical features of the master form are retrieved. The master form includes one or more anchor fields. Each anchor field has one or more anchor zones and at least one anchor segment. At least one anchor segment has global adjustment parameters and geometrical features. The extracted filled-out content is related to the retrieved geometrical features of a master form to create a new geometrical representation of the extracted filled-out content of the scanned application form. The new representation of the filled-out content based on the global adjustment parameters for the at least one anchor segment is globally adjusted. The globally adjusted filled-out content is locally adjusted.

An image forming apparatus including: a light source configured to emit a light beam based on an image signal; a deflector configured to deflect the light beam so that the light beam emitted from the light source is scanned on a surface of a photosensitive member in a main scanning direction; a storage portion configured to store a first magnification of an image with respect to a scanning position in the main scanning direction; and a controller configured to generate a second magnification of the image with respect to a reference color image, wherein the controller generates a third magnification based on the first magnification corrected based on the second magnification and the second magnification to correct the image signal based on the third magnification.

An image forming apparatus includes a photosensitive member, a light source, a deflecting unit, a storing unit, a correcting unit, and a light source driving portion. Magnification correction data is determined using a quadratic function of a variable representing a scanning position with respect to a scanning direction. Coefficients of two quadratic functions corresponding to adjacent two regions included in a plurality of scanning regions are set so that a differential value calculated at the variable corresponding to a boundary of the two regions by a differential of the quadratic function for one region and a differential value calculated at the variable corresponding to the boundary of the two regions by a differential of the quadratic function for the other region are equal to each other.

This disclosure provides a self-contained imaging device that takes digital photographs of portions of documents (such as photos or photo albums) instead of scanning those images. The imaging device uses a lens to zoom in on specific portions of the document that represent images that are to be digitized. Generally speaking, disclosed embodiments utilize a physical device having a housing, a location for retaining or holding an image to be imaged, such as a platen or image conveyance mechanism, a light source and the imaging system (which can be a digital camera). The disclosed device camera provides a low-cost mechanism that can at-once capture a high resolution image without the delays associated with most scanners.

An image forming system includes an image forming device, a reading device and a hardware processor. The image forming device includes an image former that forms an image on a sheet. The reading device includes a line sensor and a lens unit. The line sensor reads the sheet with the image formed, thereby obtaining a read image. The lens unit includes a plurality of lenses and forms an image of the sheet on the line sensor. The hardware processor identifies a sheet region of the sheet in the read image, and corrects a magnification of each subregion in a main scanning direction of the sheet region according to a characteristic of a portion in the main scanning direction of the lens unit, the portion having being used in forming an image of the subregion on the line sensor.

In accordance with an embodiment, an image forming apparatus comprises a deflector, a photoconductor, a mirror, a displacement mechanism and a control section. The deflector deflects laser light emitted from a light source to an optical path of each color in a horizontal scanning direction. The photoconductor is located in each optical path and forms an image of each color through development of an electrostatic latent image formed by being exposed by the laser light. The mirror is located in each optical path and reflects the laser light to each corresponding photoconductor. The displacement mechanism is arranged on each mirror and displaces the mirror in order to correct an inclination shift between images of respective colors. The control section corrects a magnification of the image of each color in the horizontal scanning direction according to an inclination correction amount of the image of each color.

A scanner reads a document using a sensor group and includes an optical member. When a scanning resolution in a main scanning direction is D, and a resolution of the sensor group is S, the optical member causes the sensor group to image light from the document magnified by a magnification ratio n, where n is greater than or equal to D/S and is greater than 1. The sensor group includes a plurality of sensor portions that are arrayed in L rows in a sub-scanning direction, and L is greater than or equal to n and is an integer of 3 or more. Each of the sensor portions reads a magnified image that is magnified by the magnification ratio n at each corresponding position in the main scanning direction of the document and that is guided by the optical member.
