摘要： PROBLEM TO BE SOLVED: To perform calibration at a higher speed in an image processor.SOLUTION: A color conversion storage part 14 stores a LUT for CMS for converting an input color signal into an output color signal composed of color components adaptable to an initial printing engine characteristic. A calibration information creation part 16 creates a LUT for calibration to be used in calibration to the output color signal as compensation for compensating characteristic fluctuation for a printing engine characteristic from the initial printing engine characteristic. A synthesis processing part 18 creates an integrated LUT for converting an input color signal into a calibrated output color signal by synthesis processing using the LUT for CMS and the LUT for calibration.

摘要： PROBLEM TO BE SOLVED: To achieve improved correction accuracy in the correction of color unevenness in an image plane.SOLUTION: When there are inputs of a target color and a position x of a main scanning direction forming the target color, in consideration of the color unevenness in the image plane, a conversion characteristic for color unevenness correction is generated to convert into an output color, to be output to an image forming unit, to reproduce the target color at the position x. Thereafter, a color chart is formed using the output color obtained by the conversion characteristic, and according to a color difference between colorimetric values of the color chart at a plurality of points along the main scanning direction and the target color, a corrected target value to correct the target value is calculated (118, 120 or 122, 124), so that the corrected target value is converted into an output color using the conversion characteristic (128). The above procedure is repeated until the maximum color difference between each colorimetric value and the target value becomes a tolerance value or lower.

摘要： PROBLEM TO BE SOLVED: To reproduce the line width and density of an original image even when thinning a line of a line width and a character of any size, in an electrophotographic type image forming apparatus. SOLUTION: A rasterization part generates a 1,200-dpi (dot/inch) raster image from PDL (Page Description Language) data received from the outside, and outputs it to a resolution conversion part. The raster image is developed to 2,400 dpi by the resolution conversion part, and is applied with line thinning processing two times by a line thinning processing part. As a result, the raster images having line thinning amounts of "1", "2" are respectively stored in an image memory. A tag output part of a controller generates a tag according to the line width or the like from the PDL data received from the outside, and outputs it to the resolution conversion part. The resolution conversion part develops the output tag to 2,400 dpi, and outputs it to a selection part. The selection part selects the raster image of the proper line thinning amount from the image memory in each pixel, and outputs a selection result thereof to a control part.

摘要： PROBLEM TO BE SOLVED: To provide a technology capable of suppressing occurrence of a color ghost. SOLUTION: The image forming apparatus turns two image data input to an exposure unit 19 respectively before and after one rotation of a photoreceptor drum 20 to a first image data and a second image data respectively.

摘要： PROBLEM TO BE SOLVED: To efficiently perform work when correcting color reproducibility using a plurality of methods. SOLUTION: When generating irregularity correction information (SA1), a control part specifies the color value of pixel data at a prescribed position from the read image data of a test image used in SA1 (SA2). Then, the control part calculates R1 which is a value indicating the degree of deviation from the one of ideal color reproduction characteristics on the basis of the color value (SA3). The control part decides that the updating of calibration information is needed since color reproduction characteristics are not excellent (SA5) when deciding that R1 is equal to or larger than a threshold Th1 (SA4;YES), and decides that the updating of the calibration information is not needed since the color reproduction characteristics are excellent (SA6) otherwise (SA4;NO). Thus, since the control part generates correction information only when the updating is needed, the work is efficiently performed. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To suppress production of noise and correct uneven contrast and stripes, in an image formed by an electrophotographic system.
SOLUTION: The degree of a primary component used for gradation conversion is properly revised to be proper by adjusting a density coefficient depending on high and low of a density area to which the density of a segment region belongs. Concretely, when the density of the segment region belongs to a predetermined low density region, the degree of the primary component used for the gradation conversion is lowered to first-order and second-order, when the density of the segment region belongs to a medium density region higher than the low density region, the degree of the primary component used for the gradation conversion is increased up to fourth-order from the first-order. Thus, the gradation conversion characteristic of each segment region can excellently be corrected and the gradation conversion can be executed by using the order of a degree not causing noise.
