    摘要: The characteristic variations of a printer largely influence the recognition precision of code information, and the recognition precision of code information appended to printed matter cannot often be guaranteed depending on printers. To solve this problem, a printer forms a predetermined chart, and the image forming characteristics of the printer are detected from the code information recorded on the chart. A generation method of generating code information obtained by encoding information to a regular sequence of a pixel cluster is controlled in accordance with the image forming characteristics.

    摘要: In an image forming apparatus for making a position deviation correction, a position deviation amount can be accurately calculated by stabilizing the detection result at position deviation detecting and considering an ideal correction amount and an actual correction amount to make the position deviation correction accurately. A forming unit forms a pattern for position deviation detection without making the position correction for less than one pixel by an image position correcting unit, to a pattern formed in the vicinity of a detection region of a detecting unit, and the position deviation amount is calculated by using a value of a position correction which is not made to the pattern for position deviation detection to be formed.

    摘要: Each object in input image data is separated into an area by an image area separation unit. An area determined to be a character area based on the image area separation processing is smoothened by an MTF correction unit. The resulting data is then binarized by a binarizing unit. The binarized data is split according to types of objects, and characters and line drawings are vectorized and stored in a storage unit. Alternatively, the characters and line drawings are printed out.
