    摘要： According to an aspect of the invention, an image forming apparatus includes an image correction unit and a determination unit. The image correction unit inserts a new pixel between pixels forming image data with a plurality of pixels printed using a plurality of print color materials arranged in a main scanning direction in order to correct the image width in the main scanning direction. The determination unit determines whether or not the image data is specified for print with a dot representing given information superposed. When the determination unit determines that the image data is specified for print with the dot superposed, a prohibition unit included in the image correction unit prohibits insertion of the new pixel into a pixel string of a print color material of a similar color to the print color material for the dot.

    摘要： An image processing device includes a screen processing unit and a correction processing unit. The screen processing unit executes screen processing for an image to be processed. The correction processing unit performs correction processing of correcting a distortion of an output image from an original image, based on the amount of the distortion, for (i) the image before the screen processing and (ii) the image after the screen processing. The correction amount relating to the correction processing for the image after the screen processing is a small value as compared with the correction amount relating to the correction processing for the image before the screen processing.

    摘要： The invention is a positive peak level comparator for generating a positive peak pulse when a TES (Tracking Error Signal) is higher than a predetermined positive level, a negative peak level comparator for generating a negative peak pulse when the TES is lower than a predetermined negative level, and a logic circuit for generating an output pulse when said positive peak pulse and said negative peak pulse have been alternately input thereto. The arrangement prevents the TES from being miscounted even if the TES is distrubed due to the occurrence of, for example, a noise at a level close to either said predetermined positive level or said predetermined negative level and either said peak pulse or said negative pulse is successively generated.

    摘要： A light-emitting elements emits a light beam onto a predetermined sensing position, and a reflected beam from an original is received by a light-receiving element. The light-receiving element, which is a position sensitive detector for detecting a spot position of the reflected beam, releases a pair of currents that vary according to the spot position. A signal processing circuit detects the presence or absence of the original based on the ratio of the currents. The pair of currents released by the light-receiving element fluctuate in response to changes in reflection factor due to the individual color of the original, while the ratio of the pair of currents does not fluctuate even if the reflection factor changes. Thus, detection accuracy is improved, and erroneous detection can be prevented in comparison with an arrangement wherein the presence or absence of the original is detected by detecting and comparing the amount of light.
