摘要： A positional error detection method forms, on a belt which is transported in a transport direction, positional error detection marks for detecting a positional error between image positions of first and second colors, detects the positional error detection marks on the belt, and computes the positional error based on the detected positional error detection marks. The positional error detection marks include first and second marks which are inclined in mutually opposite directions with respect to the transport direction, and third marks which are perpendicular to the transport direction.

摘要： An inclination detecting device includes processing circuitry. The processing circuitry is configured to detect, in image information that is an image of an object imaged by an imaging device at an imaging position where a background member forms a background, a first boundary between the background member and a shadow of the object at detection positions in at least one of main-scanning and sub-scanning directions on an outline of the object; detect a second boundary between the object and the shadow of the object at detection positions in at least one of the main-scanning and sub-scanning directions on the outline of the object in the image information; detect a boundary group including detection results of the second boundary at the detection positions; and detect an inclination of the object in the image information from detection results of the first boundary, the second boundary, and the boundary group.

摘要： A signal correction device includes a correction signal generator configured to generate a correction signal serving to remove noise superimposed on an input signal; a phase adjuster configured to shift a phase of the correction signal generated by the correction signal generator; a subtractor configured to generate an output signal for output by subtracting the correction signal from the input signal; a peak and bottom detector configured to detect a peak value and a bottom value of the output signal; and a determiner configured to determine a phase-shift amount of the phase adjuster from the peak value and the bottom value of the output signal detected by the peak and bottom detector. The determiner detects uncorrected noise from the peak value and the bottom value of the output signal from the subtractor, and sets the phase-shift amount such that the uncorrected noise is reduced to a minimum.

摘要： A document size detection device includes: a light source to irradiate a document with light; an imaging device to receive light reflected at the document; and circuitry to control switch on and off of the light source and movement in a sub-scanning direction of the light source, and determine a size of the document based on image data acquired by the imaging device. The circuitry is to determine a size in a main-scanning direction of the document based on: first image data acquired when the light source is switched off while the light source is at a first reading position; second image data acquired when the light source is switched on while the light source is at the first reading position; and third image data acquired when the light source is switched on while the light source is being moved from the first reading position to a second reading position.
