20080246984 | IMAGE DATA CREATION METHOD AND INFORMATION PROCESSING APPARATUS - An information processing apparatus for creating image data, comprises a setting unit adapted to set an operation condition of a print unit, a generation unit adapted to generate image data having undergone distortion correction by using distortion correction information corresponding to the set operation condition, and a transmission unit adapted to transmit the generated image data and information of the operation condition to the print unit. | 10-09-2008 |
20090129804 | IMAGE GENERATING APPARATUS AND CALIBRATION METHOD THEREFOR - To correct distortion in an optical system of an optical scanning, electrophotographic image generating apparatus, a parallel line group | 05-21-2009 |
20090284788 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF - An electrophotographic image forming apparatus increases resolution in the main scanning direction. To accomplish this, the image forming apparatus includes a light source having N light-emitting portions each configured to emit a light beam based on an input image signal, an input unit which inputs image data, a signal generation unit which extracts one-scanning image data corresponding to one scanning based on the input image data, and generates N image signals that form one-scanning image data upon composition, and a scanning control unit which scans a single track on a photosensitive body by N light beams emitted by the light source to form a latent image corresponding to one-scanning image data on the photosensitive body. | 11-19-2009 |
20100238258 | IMAGE FORMING APPARATUS AND CONTROL METHOD - An electrophotographic image forming apparatus performs latent image rendering using a plurality of light sources. The electrophotographic image forming apparatus includes a rendering time control unit that controls a latent image rendering start time for each of the light sources, a scanning time control unit that controls a scanning start time for each of the light sources, a pattern forming unit that forms a pixel pattern corresponding to pixel pattern data defined in advance on a photosensitive member, and a density detection unit that detects a density of the pixel pattern formed on the photosensitive member. The rendering time control unit and the scanning time control unit respectively control the rendering start time and the scanning start time for each of the light sources using a density value detected by the density detection unit. | 09-23-2010 |
20110286011 | IMAGE PRINTING APPARATUS, IMAGE PRINTING METHOD, AND STORAGE MEDIUM - A risk of a disadvantage was caused where the entire face of an image subjected to an interpolation or thinning processing causes an increased boundary length between a region including pixels (printing region) and a region not including pixels (paper background region) or causes a broken texture in the image. To prevent this, a transition area is provided in the image so that only the transition area can be subjected to an interpolation or thinning processing. | 11-24-2011 |
20120274950 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER-READABLE MEDIUM - An image processing apparatus comprises a reception unit configured to receive data with a first resolution, a correction unit configured to correct a coordinate system of the data with the first resolution into a coordinate system with a second resolution higher than the first resolution, a rendering unit configured to perform rendering processing for the data with the second resolution which is corrected to the coordinate system with the second resolution by the correction unit, and a resolution conversion unit configured to convert the data with the second resolution rendered by the rendering unit into the data with the first resolution by performing weighting calculation processing for a pixel in the data with the second resolution and a neighbor pixel of the pixel. | 11-01-2012 |
20150029519 | APPARATUS AND METHOD FOR PERFORMING EXPOSURE ON PHOTORECEPTOR DRUM - In a case where a determination is made that a density of a pixel of interest is greater than a threshold, or in a case where a pixel having a greater density than the threshold is present in a neighborhood of the pixel of interest at a predetermined distance from the pixel of interest, exposure with intensity corresponding to a density of the pixel of interest to which a predetermined density has not been added is performed on a photoreceptor drum at a position corresponding to the pixel of interest. Otherwise, exposure with intensity corresponding to a density of the pixel of interest to which the predetermined density has been added is performed on the photoreceptor drum at the position corresponding to the pixel of interest. | 01-29-2015 |
20150293466 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus applies a dither matrix to multi-valued image data. Then, the apparatus performs an exposure on a photoreceptor drum based on the image data obtained by using the applied dither matrix. In this process, the apparatus performs additional amount of exposure on the photoreceptor drum in a cycle equal to the cycle of the dither matrix, in addition to an amount of the exposure based on the obtained image data. | 10-15-2015 |
