20090316236 | Image processing method, printer driver, imaging apparatus, image processing apparatus, and imaging system - An image processing method is disclosed for performing an under color removal process and a black recording liquid incorporation process on an input three-color signal, and generating image data for an imaging apparatus that is configured to form a color image on a recording medium using recording liquids of cyan, magenta, yellow, and black. The method includes the steps of regulating a maximum black recording liquid incorporation amount such that glossiness of black realized in an image formed on a glossy recording medium is not degraded, setting the black to be realized by the black recording liquid until reaching the regulated maximum black recording liquid incorporation amount, and setting the black to be realized through addition of a composite of the cyan, magenta, and yellow recording liquids if the black to be realized requires an amount of the black recording liquid exceeding the regulated maximum black recording liquid incorporation amount. | 12-24-2009 |
20100265292 | INK, INK CARTRIDGE, INK JET RECORDING APPARATUS, AND INK JET RECORDING METHOD - To provide an ink jet recording method including: performing image recording on a recording medium to obtain an ink adhesion quantity of 15 g/m | 10-21-2010 |
20100265548 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT - An image processing apparatus, which performs an error diffusion on M-value image data with an error weight matrix into N-value image data, includes: a corrected-value calculating unit that calculates a corrected value by adding a first value and a second value to a pixel value corresponding to a processing-target color component of a pixel of interest, the first value being obtained by multiplying an error for each quantized pixel of the processing-target color component by the matrix, and the second value being obtained by multiplying an error for each quantized pixel of a different color component by the matrix; a quantizing unit that compares the corrected value with a quantization threshold, and outputs N-value image data; and an error diffusion unit that calculates an error at the pixel of interest by subtracting a quantization threshold from a value obtained by adding the first value to the pixel value. | 10-21-2010 |
20110102489 | IMAGE FORMING DEVICE AND IMAGE FORMING METHOD - An image forming device forms an image on a recording sheet by bidirectional recording. In the image forming device, a control part controls the image forming device. The control part includes a distance changing part that changes a sheet transporting distance for transporting the recording sheet after a forward movement of a recording head to a first transport distance and changes a sheet transporting distance for transporting the recording sheet after a backward movement of the recording head to a second transport distance, and a nozzle changing part that determines inactive nozzles which do not discharge a recording liquid among nozzles of the recording head alternately for one of the forward movement and the backward movement of the recording head. | 05-05-2011 |
20110273746 | IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, AND IMAGE PROCESSING METHOD - A disclosed image processing apparatus performs an image processing operation to execute double-side printing on both sides of an image forming medium. The image processing apparatus forms a dot font including a dot pattern of a character in a character image that has undergone a halftone process using a predetermined coefficient for mitigating show-through when the double-side printing is performed; forms a correction dot for making a correction to reduce step-like irregularities along an outline portion of the character in the character image, which correction dot is formed based on an arrangement position, a color, and a dot size of the correction dot for reproducing a gradation that has undergone the halftone process using said predetermined coefficient; and combines the dot font and the correction dot. | 11-10-2011 |
20120236054 | IMAGE FORMING APPARATUS, COMPUTER-READABLE STORAGE MEDIUM, AND IMAGE FORMING METHOD - An image forming apparatus includes a carriage that includes a head including a black nozzle array in which a plurality of nozzles are arranged and a color nozzle array in which a plurality of nozzles are arrange, the black nozzle array being disposed at a position shifted in the sub-scanning direction downstream in a medium conveying direction with respect to the color nozzle array; a conveying unit configured to convey a recording medium in a sub-scanning direction; and a control unit. The control unit forms an image by the color nozzle array in a main scanning in one direction, relatively moves the recording medium to a subsequent main-scanning position thereafter, and forms an image by the black nozzle array on the image formed by the color nozzle array in a following main scanning in the other direction so as to complete an image for one scanning area. | 09-20-2012 |
20120236057 | IMAGE FORMING APPARATUS AND COMPUTER PROGRAM PRODUCT - Print head for black material is arranged such that the black material is to be ejected later than cyan, magenta, and yellow materials on both of forward and backward strokes, and the print heads for the cyan, magenta, and yellow materials are arranged in tandem in a main-scanning direction. The first processing unit converts input image data into CMY image data and then performs black generation and undercolor removal on the CMY image data, to obtain CMYK image data. The second processing unit converts CMY image data excluding K image data from the CMYK image data into image data for use in printing in the backward direction. The on/off switching unit switches between causing and not causing the second processing unit to covert the CMY image data depending on which one of printing in the forward stroke and printing in the backward stroke is to be performed. | 09-20-2012 |
20130070303 | IMAGE PROCESSING APPARATUS, METHOD, IMAGE FORMING APPARATUS, AND STORAGE MEDIUM - The present invention provides a novel image processing apparatus that facilitates obtaining high-quality image even in low resolution without driving up costs and lowering speed. The image processing apparatus of this invention includes the line width determining unit that determines whether or not line width in image with high resolution is one pixel. The adding unit adds one pixel either above or below the line in image converted to lower resolution and makes the width of the line two pixels. | 03-21-2013 |
