Abstract: A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter. After receiving the synchronously processed pixel value from the AND gate, the counter calculates and outputs the extracted row of pixels, including the amount of pixels and the geometric patterns in the row of pixels.

Abstract: The image recording method and image recording apparatus synchronize phase of a light deflector with rotation of a drum in response to the drum start point detection signal generated each time the drum rotates once, expose the two-dimensional image of one frame formed by a group of light sources disposed two-dimensionally onto the recording medium while causing the image at rest on the recording medium relatively thereto, thereafter move the optical system in the auxiliary scanning direction by an integral multiple of a pixel pitch forming one frame as well as deflect an angle of the light deflector in the main scanning direction by one frame so as to expose the next frame and on for one rotation of the drum. When the position is dislocated in the auxiliary scanning direction at the time the recording medium is to be exposed in a subsequent one rotation of the drum, the method and apparatus correct the dislocation of the position in the auxiliary scanning direction by changing an auxiliary scanning movement speed in a non-exposure time zone between the previous and subsequent rotations of the drum.Accordingly, the method and apparatus can prevent the occurrence of streaked unevenness in the surface exposure and spiral exposure.

Abstract: To make it possible to improve a printing speed. When printing a plurality of printing sheets 14, it is possible to decrease the time for generating correction data by using a pair of correction data values to print the printing sheets 14. Therefore, it is possible to decrease the time for printing each printing sheet 14 even compared to the case of a method for generating correction data for each printing sheet 14. As a result, even when the number of sheets to be printed is large, it is possible to improve a printing speed. Moreover, when meandering states of the printing sheet 14 are changed, it is possible to prevent disorder of a printed image due to meandering of the printing sheet 14 for a long time by newly generating correction data. Furthermore, by generating (updating) only a part of correction data when newly generating the correction data, it is possible to decrease the time for generating the correction data and improve a printing speed.

Abstract: An apparatus for positioning a scanning starting point of an image scanning apparatus includes a platen, carriage, and a number of marks. The X-Y coordinate system defined by the platen has an X-axis defined by a first wide margin of the platen and a Y-axis defined by a first long margin of the platen. The carriage moves along the Y direction. The marks inside the image scanning apparatus indicate different Y coordinate values. The method for positioning a scanning starting point of an image scanning apparatus is as follows: the nearest mark to the document to be scanned is first chosen as a reference point. The vector from an image starting point of the document to be scanned to the reference point is then obtained. The carriage finally moves to the reference point chosen as a starting point and proceeds to scan.

Abstract: A printing device reads an image on a printing paper with an image pickup part. It image-processes obtained image data in a control part, and operates the positions of respective register marks (R1 to R4). It operates the quantity of displacement necessary for positioning an image. It obtains an offset count number Co for deciding an image recording starting position from the obtained quantity of displacement. It stores the obtained offset count number Co while obtaining starting position data. Then, dimensional correction data for the image is calculated. The image on the printing paper is first picked up, and the necessary quantity of displacement is calculated. A speed coefficient k is calculated for changing the rotational speed of a plate cylinder. Following this, a correction quantity by a Cd default count number previously set for deciding the image recording starting position is changed. Accordingly, the offset count number Co is calculated again on the basis of the obtained speed variable k. The obtained speed coefficient k and the offset count number Co are stored, and starting position data is obtained from both data.

Abstract: In an image reading device, light from a source document is formed in an image by an optical image-forming system including a lens and the formed image is detected by a charged coupled device (CCD) sensor. A reading line of the image read by the optical system and the CCD sensor is scanned in a vertical scanning direction. The charge accumulated in the CCD sensor is read out through a timing circuit and an analog-to-digital converter. Light from an extension of a reading line of a position-reading pattern in or on a position-reading plate is also formed into an image and detected by the CCD sensor, based on which, misregistration of a scanning position in the vertical scanning direction is detected. The image data read out by the CCD sensor is corrected by a correction circuit, based on the misregistration of a scanning position in the vertical scanning direction.

Abstract: An apparatus and method for correcting a scanning error in a flatbed scanner, can minimize the scanning error due to deviations in position or scanning of a CCD (charge-coupled device) module by determining a scanning position, a scan region, and a scan rate for each flatbed scanner. The scanning error correcting apparatus includes a white shading plate having a black patch, a reading module for reading the white shading plate and the black patch, and a controller that compares information about the black patch read by the reading module with a predetermined reference value to correct the scanning error in the flatbed scanner. Thus, the apparatus and method can secure a scanning region in horizontal and vertical directions as wide as possible for each flatbed scanner and prevent occurrences of errors in a scanned image due to deviations of the CCD module. Furthermore, the apparatus and method provide an accurately scanned image having a desired scan rate by comparing right and left sizes and the entire scan size for a currently scanned region.

Abstract: A device for quick and precise determination of a scan start point for an image scanner is disclosed. The image scanner includes a photo-processing device and a scanning platform for placing thereon a document to be scanned. The scanning platform is printed with a background region and a color block which are of different colors and located in front of the scan start point of the photo-processing device, and the color block is enclosed with the background region, and has a specified point therein being a predetermined shift to the scan start point along a specific direction. The photo-processing device moves a predetermined distance L0 from the home position to a pre-scan position overlapping with the color block, then moves a calculated distance L1 from the pre-scan position to the specified point, and moves another predetermined distance L2 from the specified point to the scan start point along the specific direction to start scanning. The distance L1 can be automatically adjusted to cover the installation error of the photo-processing device. For another image scanner disclosed herein, the movement of the distance L0 can be omitted by having the color blocks located at the home position which serves as the pre-scan position.
