20090097083 | IMAGE FORMING APPARATUS AND IMAGE PROCESSING METHOD THEREFOR - An image forming apparatus which is capable of suppressing occurrence of color moire. A second storage unit stores image data associated with at least two colors. A controller reads out the stored color-specific image data while designating a reading position in a sub scanning direction of the image data. A transfer unit transfers a color image onto a recording medium based on the read-out image data of each color. An image processing unit corrects the reading position in the sub scanning direction of the image data of each color according to profile data of each color defined based on position curve information in the main scanning direction of the transfer unit, when the controller reads out the image data. The controller regenerates the profile data if at least two pieces of the profile data satisfy a predetermined condition. | 04-16-2009 |
20090141319 | IMAGE FORMING DEVICE, IMAGE FORMING METHOD AND COMPUTER READABLE MEDIUM - The present invention relates to an image forming device that realizes accurate image forming positioning at a desired position without any complex operation about the image forming position by firmware in the image forming device that can involve the unevenness or mounting position difference of lenses of a deflection scanning device. The image forming device obtains the amount of shift in a subscanning direction of image forming from the image forming position of the image data in the main scanning direction and from the curve correction information, adds dummy data by the number of lines of shifting the reading position of the image data at the image forming start position in accordance with the amount of shift obtained, and delivers the dummy data added and the image data to an image forming component. | 06-04-2009 |
20090207430 | COLOR IMAGE FORMING APPARATUS AND COLOR IMAGE FORMING METHOD - A color image forming apparatus is provided that forms an image by correcting registration shifts during an image forming process by using image data and which prevents toner from being blown away and scattered during a fixing process by thinning pixels without making an erroneous decision. When multivalued color image is binarized, the threshold is corrected by using information on grayscale level correction. Further, when trailing phenomenon prevention operation is performed on the binarized image data, the patterns to be used for pattern matching are changed and selected according to whether the subscan direction line shifting point lies within the reference window. | 08-20-2009 |
20110141504 | IMAGE READING DEVICE FOR CORRECTING IMAGE READ FROM ORIGINAL, METHOD OF CONTROLLING THE IMAGE READING DEVICE, AND STORAGE MEDIUM - An image reading device which corrects images read from respective first and second sides of an original without increasing the total circuit size. A scanner unit (image reading device) reads an image on a front surface of an original by a front-side reading section and reads an image on a back-side of the original by a back-side reading section in a single feeding operation. The scanner unit detects a skew angle of the original read by the front-side reading section, with respect to the front-side reading section, and corrects image data read by the front-side reading section and image data read by the back-side reading section, according to the detected skew angle of the original. | 06-16-2011 |
20110149357 | IMAGE READING APPARATUS, CONTROL METHOD OF IMAGE READING APPARATUS, AND STORAGE MEDIUM - A method includes reading an image of a document obtained by a reading unit exposing the document to light with an exposure unit, causing the reading unit to perform first reading processing for reading first information obtained by causing the exposure unit to perform exposure with a first light amount, and second reading processing for reading second information obtained by causing the exposure unit to perform exposure with a second light amount that is smaller than the first light amount while no document is placed at a reading position of the reading unit, and detecting a foreign matter existing at the reading position according to a difference between the first and second information. | 06-23-2011 |
20110213996 | POWER CONTROL SYSTEM AND CONTROL METHOD FOR THE SAME - Provided is technology for enabling power saving control that allows a change of control content according to a user selection in a power control system that saves power consumed by an information processing apparatus. The power control system of the present invention include an image processing apparatus | 09-01-2011 |
20120218598 | IMAGE PROCESSING APPARATUS, SERVER APPARATUS, CONTROL METHOD THEREOF, AND STORAGE MEDIUM - When a web server generates a preview screen, the web server transmits conversion information (e.g., an image size) for generating a preview image to a multifunction peripheral (MFP). The MFP generates converted image data using the conversion information, and transmits the converted image data to a web server. | 08-30-2012 |
20130335754 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND PROGRAM - An image reading unit configured to rotate and read a front and a back of a document may deviate from an original reading position due to aged deterioration or an external physical impact and become incapable of reading an image accurately. An image processing apparatus rotates an image reading unit including a sensor in units of predetermined angles to read a white reference member, acquires luminance information about the white reference member at the respective predetermined angles of rotation, determines an angle at which the luminance information is greater than other pieces of the luminance information among a plurality of pieces of the acquired luminance information at the respective predetermined angles, and rotates the image reading unit based on the determined angle to correct a reference position of the image reading unit. | 12-19-2013 |
20130335788 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM - An image processing apparatus includes an acquisition unit configured to acquire luminance information of a white reference member by reading the white reference member with an image reading unit including a sensor while rotating the image reading unit in units of a predetermined angle, and a correction unit configured to correct the luminance information acquired by the acquisition unit using a correction coefficient predetermined for each rotation angle of the image reading unit. | 12-19-2013 |
