    摘要: A shading correction system is used in an image scanning apparatus which stores shading data which are obtained by scanning a white substrate and carries out a shading correction on the image information which is obtained by scanning an intended image by use of the stored shading data. The white substrate is scanned a plurality of times at different locations thereof and previous shading data stored in a memory are compared with present shading data so as to renew the contents of the memory depending on the compared result. The renewal of the contents of the memory is carried out in N stages, where each of the N stages carry out the comparing and renewing operation for one of N different groups of scans over the white substrate for one of N different picture element groups each comprising 1/N a total number of picture elements in each scan.

    摘要: Stop marks are printed on a document such as a bank passbook to indicate the position of the last data entry. The passbook is fed into the present apparatus until the lowermost stop mark is sensed. The passbook is stopped after a predetermined number of timing pulses have been counted after detection of the stop mark and another stop mark is printed on the passbook. The density of the new stop mark is sensed and, if insufficient, more stop marks are printed on top of the new stop mark until the sensed density becomes sufficient. Each stop mark may comprise two or more parallel lines which must be detected separately.

    摘要: An image processing apparatus which can produce improved quality copies by taking into account the effects which normally occur when successive copies of copies are made. When a document is to be copied, image information is input to a processing device relating to certain parameters associated with the image characteristics such as, for example, the toner density, thickness of the image information, type of copier used, amount of toner available at the time of copying, etc. This image information is then stored on the document copy in the form of a bar code which will change as successive copies of copies are made in such a way that the image quality of the copies is not degraded. The image information contained on the document via the bar code is combined with new input image information supplied by an operator, whereby the two sets of information are combined in a central processing unit in order to determine the necessary amount of correction processing required to compensate for the fact that the image has been reproduced a number of times whereby copies are made from previous copies. In this manner, the original document quality can be maintained.

    摘要: A specific mark adding unit adds a specific mark to a read-in image and a specific mark detecting unit detects the specific mark present in a read-in image. Further, a control unit changes a mode in which a read-in image is duplicated from an ordinary duplicating mode into a specific duplicating mode, the mode changing being made if the specific mark detecting unit has detected the specific mark present in the read-in image. The specific mode comprises a mode in which the read-in image is invalidated in data before being used in the duplicating operation. A unit is further provided causing the specific-mark adding function of the specific mark adding unit either to be activated or not to be activated. A unit is further provided causing the mode changing function of the mode changing unit either to be activated or not to be activated.

    摘要: An image recorder for recording an image by reading image data produced by quantizing the image pixel by pixel, subjecting the read image data to image processing, and then manipulating a laser beam modulated by pulse width modulation. A pixel of interest is recorded in a position which is controllable depending on the presence/absence or the densities of pixel data of pixels adjoining the pixel of interest. A laser beam is modulated by pulse width modulation, while the phase or the timing of pulses is controlled to control the recording position, whereby control circuitry is simple and economical.

    摘要: A two-color image recorder for reproducing a black and a red image component of an original document on a single paper includes a scanner which sequentially performs a first reading operation which omits the red component and a second reading operation which does not omit it. Image data produced by the first reading operation are written in an image memory. While an image data control unit delivers processed image data to a laser printer, the laser printer prints them out by performing an electrophotographic process two consecutive times with a single paper. A plurality of filters each having a different spectral characteristic are selectively brought into an optical path defined in the scanner by filter selecting means.
