Abstract: An image sensor controller and methods achieve faster image reading speeds by controlling the frequency of image sensor transfer clocks φ1, φ2 in accordance with the particular output period. Such an image sensor controller includes a drive controller that supplies to a transfer section of the image sensor transfer clocks φ1, φ2 whose clock frequency during dummy pixel output periods is faster than it is during an effective pixel output period, or whose clock frequency during non-reading pixel output periods is faster than it is during a reading pixel output period. A pattern selector selects among clock patterns in a table for setting φ1, φ2 according to the output periods of the image sensor. Even when the clock frequency of φ1, φ2 changes, a transfer clock ADCK signal can be supplied at a constant clock frequency to an A/D converter.

Abstract: A system for generating a warped contone image that compensates for beam scan trajectory distortions. The system includes an image buffer for storing a portion of a received contone image. An interpolation coefficient generator provides interpolation coefficients associated with a warped pixel within the warped contone image in response to an input identifying the warped pixel. A pixel interpolator is coupled to the image buffer and the interpolation coefficient generator and provides an output signal that identifies the warped pixel within the warped contone image. The pixel interpolator further retrieves pixels from the contone image stored in the image buffer using the interpolation coefficients and generates the warped pixel by combining the retrieved pixels into a single pixel value.

Abstract: The invention concerns an image forming apparatus provided with an automatic writing-position determining device for forming an image always at a correct position on the recording material. The image forming apparatus includes an image forming section to form an image by writing each of scanning lines, an end position detecting section to detect an end position of a recording material in a direction orthogonal to a conveyance direction of the recording material, and a selecting section to select either an automatic writing-position determining mode or a predetermined writing-position determining mode. When the selecting section selects the automatic writing-position determining mode, the image forming section commences an image writing action from a writing start position determined on the basis of a detected result of the end position detecting device. When the selecting section selects the predetermined writing-position determining mode, the image forming section commences the image writing action from a predetermined writing start position set in advance.
