摘要： In an image forming apparatus employing a multi-beam method, the total emission period of time is stored for each laser beam. In accordance with the total emission periods of the laser beams, the laser beam used for SOS is switched, so that the total emission periods are kept almost equal to each other. When the laser beam used for the SOS is switched, the adjustment processing for correcting misalignment of the laser beams in the main scanning direction is changed in accordance with the current laser beam used for the SOS, and the emitting order of the laser beams for the APC is also accordingly changed.

摘要： A method and apparatus for correcting image parameters for each of several image forming apparatuses networked together are provided. In the present method and apparatus, one device, which can be one of the networked image forming apparatuses, operates as an image parameter correction apparatus. The image parameter correction apparatus reads in a prescribed image formed by each image forming apparatus, and calculates image parameter correction values for each image forming apparatus. The image parameter correction values for each image forming apparatus are calculated by comparing image parameters for the corresponding scanned prescribed image with reference image parameters. The image parameter correction values for each image forming apparatus are then transmitted to the corresponding image forming apparatus. In the case where one of the networked image forming apparatuses serves as the image parameter correction apparatus, that apparatus also forms a prescribed image, and derives the reference image parameters from its own prescribed image, which is scanned in along with the prescribed images formed by the other image forming apparatuses.

摘要： It is objected to provide an image processing apparatus achieving decrease of memory volume to be used, simplified print process, and enhancement of productivity. Firstly, a plurality of image data are recorded in memories provided for respective colors. Based on the image data or mode selection by a user, it is determined that whether a multi-color image or a monochrome image is to be outputted. Next, memories 302 of respective colors transmit image data of respective colors to a computing unit 304 in accordance with readout-timing signals from a timing selector 305. In case a multi-color image is to be outputted, the timing selector 305 transmits readout-timing signals of respective colors taking time difference length of which is predetermined for each color. In case a monochrome image is to be outputted, the timing selector 305 transmits readout-timing signals of respective color simultaneously. A computing unit 304 forms monochrome image data in accordance with image data of respective colors, whereby process of monochrome print is simplified.

摘要： 1,800 dpi binary image data is divided into 3-bit data groups or 2-bit data groups, and is input from an input unit 11 to a tone setting unit 12 and a print position controller 13. Each group of 3-bit image data is converted into 8-bit tone data and 2-bit attribute data by the tone setting unit 12 and the print position controller 13, respectively, and both sets of post-conversion data are input to a pulse width modulation unit 15 at the same time. Because all 3-bit data is handled at the same time, the input and output operation clock signals can stay the same as for a 600 dpi resolution.
