摘要： An image forming apparatus includes a skew correcting unit that performs skew correction by dividing an input image that has undergone a halftone process into image data in a predetermined skew correction area in a main scanning direction and by shifting the image data in the skew correction area in a sub-scanning direction; an edge detecting unit that detects whether a pixel at a division position is an edge pixel based on concentrations of a set of pixels including the pixel at the division position; a correction area determining unit that, if detected that the pixel at the division position is the edge pixel, determines a correction area that is an area of pixels including the edge pixel to be subjected to concentration correction within the skew correction area; and an edge correcting unit that corrects concentrations of the pixels within the correction area.

摘要： A pattern generating unit generates correction patterns on a transfer belt. Detection sensors detect the correction patterns, and amounts of magnification correction, amounts of misregistration in the main- and the sub-scanning direction are calculated. The amount of skew between each of colors is then calculated, and a position where an image is divided and a direction for shifting a divided image are determined. Possible dividing-positions are also determined, and a calculated dividing position and each of the possible dividing positions are compared with one another. Then, a possible dividing position closest to the calculated dividing position is set as an actual dividing position.

摘要： An image forming apparatus capable of minimizing degradation in density correction as a part of skew correction includes a noise-occurrence determining unit, a correction-target-pixel selecting unit, a density correcting unit, and a phase correcting unit. When the noise-occurrence determining unit determines that noise would appear, the density correcting unit performs density correction on a correction target pixel that is determined by the correction-target-pixel selecting unit. The phase correcting unit corrects an output point in time of image data of the density-corrected correction target pixel in a pixel period during which the image data can be output so as to output the image data at a position displaced away from a shift position or toward a shift position.

摘要： An image forming apparatus capable of accurately compensating an increase or decrease of a toner area coverage resulting from shifting that is performed to correct skew is provided. A color density of image data represented by a correction target pixel is corrected such that the increase or decrease in the toner area coverage on the correction target pixel is compensated excluding a toner area coverage on the correction target pixel covered by a toner image that would be formed based on a color density of image data to be represented by a neighboring pixel of the correction target pixel. This effectively reduces banding noise on an output of the image data and prevents degradation in image quality.

摘要： Vertices of a polygon model M0 are sorted into those on which rays are projected (visible-surface vertices M01) and those on which rays are not projected (hidden-surface vertices M02) based on normal vectors V2 of the vertices of the polygon model M0 and a light source vector V1, and shadow models (shadow volumes) M1, M2, M3 are generated by moving the hidden-surface vertices in a direction of the light source vector V1. Shadow images can be easily created by applying stenciling to these shadow models.
