| 20100039490 | METHODS AND APPARATUS FOR APPLYING PATTERNS OF NON-CONTIGUOUS FEATURES - A pattern of non-contiguous features that can be imaged in one pass of a multi-channel imaging head is divided into sets of the non-contiguous features. Each set of the non-contiguous features is imaged separately during a single scan of the multi-channel imaging head. The pattern can be completely imaged after all of the sets have been separately imaged. The non-contiguous features of one set may be interleaved with the non-contiguous features of another one of the sets. | 02-18-2010 |
| 347252000 | By adjusting pulse width of light beam | 2 |
| 20100103240 | MULTIBEAM LASER CONTROL DEVICE FOR IMAGE FORMING APPARATUS - An image data is pre-processed in parallel by a pre-processing unit (A) and a pre-processing unit (B) arranged in parallel. The image data is transferred in synchronization with an image processing signal obtained by ORing a BD signal and an interpolation signal. Laser scanning for plural beams of a multi-laser beam is performed in synchronization with the BD signal. Color matching processing or zeronization processing for the multi-laser beam is performed in synchronization with the image processing signal. | 04-29-2010 |
| 20150145943 | ELECTRONIC BANDING COMPENSATION (EBC) OF HALFTONE-INTERACTION BANDING USING VARIABLE BEAM DELAYS - Disclosed are methods and systems for compensating for process direction banding associated with a document processing system including a ROS. According to one exemplary embodiment, a ROS driver uses a plurality of beam delay/advance values to compensate for banding caused by an interaction of a halftone pattern and process direction density variations associated with the ROS. | 05-28-2015 |
| 347253000 | By varying intensity of light beam | 1 |
| 20100277561 | LASER REACTIVE MEDIA AND APPARATUS AND METHOD FOR WRITING AN IMAGE ONTO SUCH MEDIA - An optical disk label writing method for writing a label on an optical disc uses a similar writing operation to that used to write data to the disc. The disc has a label side including a laser reactive material for forming the label image, and a tracking format that can be tracked by a writing laser in a similar way to a writing operation. A computer program is provided for converting a label image to a disk image file for writing to the label side. | 11-04-2010 |
| 347254000 | By varying dotting density | 3 |
| 20090135242 | Method and apparatus for producing an image - A method of producing an image that can eliminate an fθ lens is provided. This method of producing an image includes producing the image from a plurality of dots with varying intervals that are to be formed by linearly scanning an image forming surface with light that has been modulated using image data for producing by a polygon mirror that rotates at a constant angular velocity, and generating, before the producing the image, the image data for producing to form the image with the plurality of dots with varying intervals from original image data that forms a target output image with a plurality of dots with constant intervals. The step of generating the image data for producing includes setting a state of a first dot included in the plurality of dots with varying intervals at a state of a second dot that is included in the plurality of dots with constant intervals obtained from the original data and is at a position that is close to a position of the first dot. | 05-28-2009 |
| 20090135243 | IMAGE FORMING APPARATUS AND ITS CONTROL METHOD - A first process unit replaces a portion of pixels in a pixel sequence forming a first scanning line of a first color by a different portion of pixels in a pixel sequence forming a second scanning line of the first color. A second process unit performs a thicken process to a pixel sequence of a scanning line of a second color superimposed on the first line of the first color to thicken the pixel sequence of the scanning line of the second color. The pixel sequence of the scanning line to be thickened corresponds a replacement point of the replaced pixel of the first color. | 05-28-2009 |
| 20120256999 | PRINTING IMAGE DATA GENERATING DEVICE, THERMAL TRANSFER PRINTER, AND COMPUTER PROGRAM - A printing image data generating device generates printing image data for a thermal transfer printer that heats a thermal head generating friction force depending on grayscale values to thermally transfer ink. The printing image data generating device includes: an image data acquirer configured to acquire image data as a printing subject; a density deviation line specifying section configured to specify density deviation lines at which density after printing is estimated to deviate from desired density attributed to sudden change in the friction force; a correction-subject pixel specifying section configured to specify, as a correction-subject pixel, a pixel whose variation degree of the grayscale value is lower than a predetermined value; a correcting section configured to correct the grayscale value of the specified correction-subject pixel in such a direction as to eliminate density deviation; and a generating section configured to generate the printing image data based on image data after correction. | 10-11-2012 |
