    摘要: A system controller includes an optical sensor that is arranged on a carriage and detects a tip and an edge of recording paper. The system controller moves, according to a detection signal, the carriage in a main scanning direction and the recording paper in a sub-scanning direction at predetermined timing to form an image on the recording paper. After detection of the tip of the recording paper before printing, the system controller moves the carriage in the main scanning direction until the optical sensor detects at least one edge of the recording paper to specify the position of the recording paper. Based on the specified position, the system controller adjusts a position on the recording paper where the image is to be formed.

    摘要: A method to be used within a document image capture device, such as a document scanner (10) of detecting and measuring the document skew (25) while the document is still entering the imaging area and then effecting a rotation of the camera to accommodate the document skew so that the resulting image taken is not skewed. This can be accomplished by one of several methods, such as rotating the entire camera, rotating only the sensor element, or rotating another element in the optical path such as a prism. Use of the methods incorporated in this invention does not require the document motion to be stopped to measure and accommodate skew or to take the image.

    摘要: A reading time setting section (44) determines a read area for an imaging section (25) on the basis of color chart positional data (id). The imaging section (25) reads an image on printing paper during the reading time and readout image data (rd) is stored in an image data storage section (45). A reference mark detecting section (46) detects the positions of reference marks from the readout image data (rd). A color chart actual position calculation section (47) corrects a tilt of a color chart determined from the positions of the reference marks and calculates an actual position of each of color chart fields (cr). An image data readout section (48) reads out image data on a color chart field corresponding to the calculated actual position. At the same time, image data on a white color field immediately above the color chart field is also read out. A white color correction section (49) produces a white reference on the basis of the image data on the white color field and corrects the image data on the color chart field. A color chart information determination section (50) measures color chart information, such as a color density and a dot percentage, about each of the color chart fields. This printing press determines a reading time on the basis of the position of the color chart at the time of printing plate recording and thereby allows imaging of an area including the color chart on the printing paper being transported.

    摘要: This invention provides an image forming apparatus and an image forming method in which even if paper position aberration occurs, printed image position aberration is prevented from occurring by a simple methanism. A paper position aberration detecting sensor including a light emitting element and a light receiving element is disposed in the paper conveying path of the image forming apparatus, and the amount of paper position aberration in paper conveyance is detected by a counter, and on the basis of the result of the detection, a CPU controls the writing start position of a printed image.

    摘要: An image processing apparatus that eliminates a complicated operation when a document image is input. The apparatus has an image input device for inputting a document image. A detection device detects displacement of the document image input by the input device. A determination device determines the input conditions of the image input device when the displacement detected by the detection device is not greater than a predetermined value. A control device controls the input device based on the input conditions determined by the determination device so as to cause the input device to input the document image.
