20100182623 | IMAGE ENLARGEMENT METHOD, IMAGE ENLARGEMENT APPARATUS, AND IMAGE FORMING APPARATUS - Virtual pixels not included in input image data are arranged before a first input pixel and after a last input pixel of an input pixel array, respectively. A position of a first output pixel is determined so that a difference between a position of the first input pixel and the position of the first output pixel equals a difference between a position of the last input pixel and a position of a last output pixel. Pixel data of an output pixel before the first input pixel is interpolated based on pixel data of the virtual pixel before the first input pixel and pixel data of the first input pixel. Pixel data of an output pixel after the last input pixel is interpolated based on pixel data of the virtual pixel arranged after the last input pixel and pixel data of the last input pixel. | 07-22-2010 |

The determination unit determines whether the document is a color document, according to whether a color image is included in an image in a predetermined region of the first side read by the first reading unit, and in an image in a region that is different from the predetermined region in the first side and read by the second reading unit. | 08-11-2011 |
20120147403 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - If pixel segment insertion/extraction control by random number control which is uniform irrespective of a type of image data is performed, in the case of a character or diagram, main scanning positions where the pixel-segment insertion/extraction is executed become discontinuous in a sub-scanning direction, and image quality deteriorates. To solve the above problem, there is provided an image forming apparatus having: a unit for dividing an image into a plurality of areas in the main scanning direction; a unit for setting a reference area for performing pixel segment insertion/extraction control in each of divided areas; and a unit for deciding a position where the pixel segment insertion/extraction control in each of the divided area, in accordance with attribute information of image data in the set reference area. | 06-14-2012 |
20120194827 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus multiplies a first clock to drive the apparatus, thereby forming a second clock, and holds (1) a frequency of a third clock used by a print unit of the apparatus, (2) a magnification setting of the multiplying, (3) a resolution of the print unit, and (4) a micro zoom ratio. The apparatus sets a magnification of the multiplying based on the held values, discriminates whether a pixel is a target pixel to which a micro zoom is executed by using the held micro zoom ratio, and switches a count comparison value of the second clock formed by the multiplying based on the discrimination, thereby forming the third clock. The apparatus then forms a pixel segment based on image data of the target pixel corresponding to the discrimination and inserts the formed pixel segment based on a period of the third clock. | 08-02-2012 |
