摘要： An image processing apparatus includes a pixel number transforming section for processing input image data composed of a plurality of regions, each being represented by a plurality of pixels with a pixel number transformation, by performing an interpolation or a decrimation on a pixel. It further includes a region decision value extracting section for extracting a region decision value of a region that a target pixel belongs to, based on characteristic amounts representing characteristics of a block composed of the target pixel and a plurality of pixels around the target pixel, each pixel of the image data being considered to be the target pixel. A controller controls a sequential order of a filtering process and pixel number transformation process to be applied to a region, based upon the transformation increasing or reducing a number of pixels in a region. Finally, a region decision value transforming section is included for calculating a region decision value of each region processed with the pixel number transforming process by an interpolation or a decrimation of the region decision value as extracted from the input image data.

摘要： The present invention relates to image forming device such as copying machines and laser printers, which use an electrophotographic (xerognaphic) process. A simple control method without using any additional complex means can equalize a surface potentional of a light-sensitive drum to keep a light-quality of an image formed even for the first rotation of the light-sensitive drum. A charge-removal prohibiting means, a charge-potentional changing means and a developing bias-potentional changing means are controlled in accordance with an extent of a change of a surface potential of a light-sensitive body, which depends upon a light fatigue and an ambient temperature of the light-sensitive body and/or a pause after a preceding image process.

摘要： A process control apparatus of electrophotographic apparatus has an optical sensor for optically detecting the density of toner patches formed on a photoreceptor drum. The present apparatus is further provided with a control device for controlling lamps for the copying process, chargers and other elements. A toner patch is formed on the photoreceptor so as to be located between every two toner images for a copying operation. The control device controls the lamps, chargers and other elements in accordance with the result of the toner patches detected by the optical sensor so as to stabilize the copying picture quality. With the arrangement, it is avoided that the job efficiency during the copying operation deteriorates, and the control data obtained from the toner patches is soon used for the toner image formation for the copying operation, thereby ensuring that the process control improves in accuracy.

摘要： The change in an output voltage when a control voltage is changed is calculated, and the change in the control voltage divided by the calculated change in the output voltage is defined as a sensitivity coefficient. The sensitivity coefficient is recalculated for each predetermined time interval or whenever a predetermined condition is satisfied, and the control voltage is corrected based on the recalculated sensitivity coefficient. Example of the predetermined condition include the time of start-up of the apparatus, the time at which the accumulated number of printed sheets reaches a predetermined number, and the time of carrying out process control.
