An image forming apparatus includes a conveyance part, an image forming part, a sheet detection sensor, a sensor unit, and a controller. The sheet detection sensor, in which a plurality of sensor blocks each with a plurality of sensor elements mounted thereon at specified intervals are arrayed in a sheet width direction, detects an edge position in the sheet width direction on a basis of scanning image data formed by reading of the sheet. The controller is enabled to execute a calibration of inserting, into the scanning image data, interpolation pixels for compensating an error between an edge position detected by the scanning image data and an actual edge position.

In accordance with an embodiment, an image reading apparatus comprises a conveyance system, a reading section, a movement sensor and a processor. The conveyance system conveys a document in a conveyance route including a reading position. The reading section reads an image on a surface of the document passing through the reading position. The movement sensor detects a conveyance speed of the document conveyed by the conveyance system. In a case in which the conveyance speed of the document detected by the movement sensor differs from a reference speed, if the conveyance speed of the document is within an adjustable range, the processor performs control to adjust a reading processing in response to the conveyance speed of the document.

An image capture and output method comprises steps of providing an image capture device, continuously capturing a plurality of line images from an initial position and recording a position information corresponded to each line image, calculating the difference between the position information of the first line image and the initial position and the differences between the position information of each of the rest line images and a former one of the line image to obtain a fill information, filling each line image into an image buffer according to the fill information, and outputting the image buffer as a product image. Therefore, the deformation issue is effectively solved, the storage memory is saved, and the manufacturing cost is lowered.
