20090018881 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM - A disclosed image processing apparatus includes an adjusting unit configured to convert input image data into image formation data, an arithmetic unit configured to calculate an image formation ink cost based on the converted image formation data, and a determining unit configured to compare the calculated image formation ink cost with a black-and-white image formation ink cost, wherein the calculated image formation ink cost is fixed based on a determination result of the first determining unit. | 01-15-2009 |
20100309243 | IMAGE PROCESSING METHOD, RECORDING MEDIUM, AND IMAGE PROCESSING APPARATUS - If an input image is black, an image is formed with a black ink and at least one color ink. A usage of the black ink per unit area is 40% to 100% of a reference usage of the black ink per unit area in a case of forming the image at the same density with only the black ink. A usage of the color ink per unit area is 2% to 20% of the reference usage. A dot of the black ink and a dot of the color are arranged at the same position. | 12-09-2010 |
20110170142 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, PROGRAM, RECORDING MEDIUM, PRINTING SYSTEM, IMAGE FORMING APPARATUS - An image processing apparatus for converting input image data into output image data for an image forming apparatus configured to output an image with the use of coloring material, which includes a unit configured to perform a coloring-material usage amount reduction process of converting the input image data into the output image data such that an amount of the coloring material used for color-printing the input image data becomes a target coloring-material usage amount defined based on a monochrome-printing coloring-material usage amount required for monochrome-printing the input image data. | 07-14-2011 |
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 |
20140061311 | IMAGE PROCESSING APPARATUS, IMAGE RECORDING APPARATUS, IMAGE PROCESSING METHOD, AND RECORDING MEDIUM STORING AN IMAGE PROCESSING PROGRAM - In an image processing apparatus, after a rasterizer checks resolution of raster data, if the resolution of the raster data is lower than a predefined resolution, a barcode detector analyzes the raster data and detects a barcode area. If there is a barcode area, a barcode direction determining unit determines barcode direction, and a resolution convertor enhances resolution of the barcode on black planes in a direction perpendicular to the bar direction of the barcode. | 03-06-2014 |
20140153056 | IMAGE PROCESSING METHOD, COMPUTER-READABLE STORAGE MEDIUM, AND INFORMATION PROCESSING APPARATUS - An image processing method includes dividing a first image into regions according to content of the first image; generating a second image by converting a gradation of pixels of the first image into a gradation of pixels expressible in an image forming apparatus for each region; generating a piece of simulation information of a result of the image forming/outputting process based on the second image and nozzle characteristic information of the image forming apparatus; calculating an error between the first image and a third image for each of the regions, the third image being obtained by converting the piece of simulation information with the gradation of pixels of the first image; and deciding one of the second images as rendering information used to cause the image forming apparatus to perform an image forming/outputting process, based on the calculated errors between the first image and the third images. | 06-05-2014 |
