20080259359 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, COMPUTER PROGRAM, AND STORAGE MEDIUM - The present invention provides an image processing apparatus, and an image processing method, which can reproduce an edge portion with a high resolution in a high resolution raster image, and suppress image degradation such as a jaggy, while suppressing processing cost. In the present invention, an image processing part divides image data of raster data into blocks of M×N pixels (M, N are integers of 1 or more and also at least one of M and N is an integer of 2 or more). Then, the part performs color rounding processing in the block and counts the number of colors in the block. Subsequently, when the number of colors existing in the block is two, the part acquires shape information about arrangement of the two colors. Then, the part stores the shape information and color information for a first color and color information for a second color. | 10-23-2008 |
20080260273 | IMAGE PROCESSING APPARATUS AND METHOD - An object of this invention is to increase the encoding efficiency of attribute data of each pixel of image data by using the fact that the probability that the attribute flag data of adjacent pixels have the same bit position is higher than the probability that the attribute flag data of adjacent pixels have the same value. In the first phase, to encode 32×32 attribute data having a size of 8 bits corresponding to one pixel, input attribute data is directly output to an encoding unit and encoded. In the second phase, “7” is set in a variable i as the initial value. Eight attribute data are input. Eight-bit data including bits i is generated and output to the encoding unit. The data of bits | 10-23-2008 |
20090097072 | IMAGE PROCESSOR AND IMAGE PROCESSING METHOD - An object of the present invention is to provide an image processor capable of generating an image from which a user-designated color component has been removed and performing a color/monochrome determination correctly. In order to complete the task, an image processor according to the present invention comprises a removal unit that removes a removal color part from a read image, and a determination unit that determines whether the read image from which the removal color part has been removed by the removal unit is a monochrome image or a color image. | 04-16-2009 |
20090161124 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND COMPUTER PROGRAM - A problem of the present invention is to prevent showthrough of a rear side image to a front side image without using any complicated processing at a time of reading out both sides of a document. To solve the problem, an image processing apparatus in accordance with the present invention reads out image information on the front side and rear side of a document; calculates a first background level from the image information on the front side; calculates a second background level by adjusting the first background level according to the first background level calculated and the density of the image information on the rear side; and removes the background of the front side using the second background level. | 06-25-2009 |

20130128290 | IMAGE PROCESSING APPARATUS AND ITS METHOD - An unnatural color change which occurs when combining trapping and spatial filter processing is suppressed. When image data is input, it is determined whether to perform trapping at the position of the pixel of interest of the input image data, and trapping is performed for the input image data. In addition, spatial filter processing is performed for the pixel of interest of the input data, an output of the trapping and that of the filter processing are weighted, and image data to be output is calculated. | 05-23-2013 |
20140369599 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - Edge enhancement processing is executed by obtaining a sum of whiteness degrees around a target pixel, to which edge enhancement is to be applied, and by adjusting the amount of edge enhancement such that the degree of edge enhancement decreases as the sum of whiteness degrees increases, and the degree of edge enhancement increases as the sum of whiteness degrees decreases. A whiteness degree is a value indicating the extent to which a pixel is close to white, and a sum of whiteness degrees indicates the extent to which the color around the target pixel is whitish. | 12-18-2014 |
20150185675 | IMAGE FORMING APPARATUS AND ADJUSTMENT METHOD THEREFOR - An amount of used toner is estimated based on the density independent of a recording medium, which is obtained from an intermediate transfer member, and on the density dependent on a recording medium, which is obtained from a recording medium. Patches are formed on a target print medium both under a process condition using the estimated toner amount, and under process conditions in which the toner amount changes on the basis of the estimated toner amount. Densities of the patches are measured, a process condition yielding a target density is identified, an image is formed under the identified condition, an amount of toner consumed to yield the target density under the identified condition is used as the largest toner amount for a single color component, and a toner mounting amount serving as an upper limit is converted into a density scale. | 07-02-2015 |
