Abstract: In a color image forming apparatus, component color images formed by respective image forming stations are sometimes displaced as they are transferred onto recording paper. Therefore, a set pattern image (Q0) with no displacement at all is recorded onto recording paper as a set pattern image (Q1). In this set pattern image, the centers of auxiliary patterns (Y1, C1, M1) are displaced in an auxiliary scan direction off a referential straight line (H) passing through the centers of primary patterns (K1, K1null). The image forming apparatus causes the set pattern image to be read, measures the displacements (nullY1, nullC1, nullM1) of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and adjusts writing timings in the auxiliary scan direction so that the displacements become 0. As a result, the color image recorded on the recording paper shows improved quality. Therefore, the resist of the component color images can be corrected by measuring the displacements of the component color images without being affected by a tilt of the patterns on the recording paper or irregularity in operation of the image forming stations for recording the component color images.

Abstract: An image capture and output method comprises steps of providing an image capture device, continuously capturing a plurality of line images from an initial position and recording a position information corresponded to each line image, calculating the difference between the position information of the first line image and the initial position and the differences between the position information of each of the rest line images and a former one of the line image to obtain a fill information, filling each line image into an image buffer according to the fill information, and outputting the image buffer as a product image. Therefore, the deformation issue is effectively solved, the storage memory is saved, and the manufacturing cost is lowered.

The image forming apparatus causes the set pattern image to be read, measures the displacements of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and compensates for the displacements, such as by adjusting writing timings in the auxiliary scan direction so that the displacements become zero.
