Abstract: An image processing apparatus includes a correcting unit that performs enlarging or reducing correction on an image to be processed by determining an arrangement of pixels that are to be added to or deleted from gradational image data of the image to be processed based on an angle at which the pixels are to be arranged with respect to a horizontal direction of the image to be processed or with respect to a vertical direction of the image to be processed, and a pixel array control unit that changes the angle at which the pixels are arranged based on a test image of the image data to be processed after being corrected by the correcting unit.

Abstract: An image forming apparatus forms on a photoconductive body an evaluation chart including first patterns and second patterns. In the first pattern, with respect to a row of dots formed in a main scan direction by a predetermined light beam, a row of dots formed by a next light beam is shifted in the main scan direction, and in the second pattern, with respect to the row of dots formed in the main scan direction by the predetermined light beam, the row of dots formed by the next light beam is shifted in the main scan direction but in a direction opposite to a shift direction of the first pattern. The evaluation chart includes a first pattern group which is formed by the first patterns which are repeated, and a second pattern group which is formed by the second patterns which are repeated.

Abstract: An image forming apparatus includes a condition determining device that calculates a deviation amount of image data from a normal condition and determines if the image forming apparatus is in an abnormal condition. An abnormal section specifying device specifies an abnormal section in the image forming apparatus based on a condition of the image forming apparatus. An image processing device executes image processing for abnormal use in accordance with an output of the abnormal section specifying device when the image data condition determining device determines that the image forming apparatus is in an abnormal condition. A service person call output device outputs a service person call signal indicative of calling a service person to a center when the image data condition determining device determines that the image forming apparatus is in an abnormal condition.

Abstract: A main vector: m^=(mx, my) and a sub-vector: s^=(sx, sy) determining cyclic structure of a basic matrix are defined, and a positional vector for a pixel configuring the basic matrix Pi^=(Pix, Piy) is defined, where the suffix i denotes an i-th pixel configuring the basic matrix. Then, the pixels configuring the basic matrix are arranged in such a manner as to satisfy the cyclic structure, and transformation of Pi^→Pi^+km^+ls^ is carried out where k and l are arbitrary integers, and may be negative values. Then a new shape of the basic matrix is obtained with Pi^+km^+ls^ as a new pixel positional vector Pi^.

Abstract: A semiconductor laser driver is designed to detect a semiconductor laser output and control a drive voltage or current of a semiconductor laser so as to set a detected laser output to be a predetermined constant laser output. The laser driver includes an integrator for integrating the detected laser output, thereby utilizing an integrated signal as a semiconductor laser drive signal. The integrator integrates the difference between a voltage corresponding to the detected laser output and a reference voltage corresponding to the predetermined constant laser output.
