Abstract:
A digital color copying machine comprising a test mode is disclosed. In the test mode, image data corresponding to a partial area of an original document indicated is stored in a RAM, and thereafter, the image data stored in the RAM is read out repeatedly, and plural test images for which the color correction is made with different color balances respectively are formed as mosaic monitor images on a recording medium. Then, one of plural test images is selected, and a copy of document having a color balance of the selected test image is produced. The state of the selected color balance is displayed on a display section.

In the test mode, image data corresponding to a partial area of an original document indicated is stored in a RAM, and thereafter, the image data stored in the RAM is read out repeatedly, and plural test images for which the color correction is made with different color tones respectively are formed as a mosaic monitor image on a recording medium. Then, one of plural test images is selected, and a copy of document having a color tone of the selected test image is produced. The test mode is canceled if a test image has not been selected during a predetermined time period.
Abstract:
A digital color copying machine including a mosaic monitor mode is disclosed. In the mosaic monitor mode, image data corresponding to a partial area of an original document is stored in a RAM. The image data is then read repeatedly from the RAM and a plurality of images of the partial area which have been subjected to different color adjustments are formed on a recording medium, so as to form a mosaic monitor image. The operator may then choose a desired color adjustment from the plurality of color adjusted images. Also, an operator may vary a parameter in the color adjustment process to obtain either greater or more minute color adjustments.
Abstract:
There are disclosed an image forming apparatus such as a digital copying machine and an image forming method. In the image forming apparatus and method, there are transformed supplied reference color image data into plural sample image data having color tones stepwisely different from each other by multiplying the reference color image data one by one by supplied plural color adjustment coefficients, and then, there are recorded plural sample images corresponding to the plural sample image data on a piece of recording paper. When the operator selects one of the plural sample images, a controller alters the supplied reference color image data into another reference color image data responsive to color adjustment coefficients of the selected one of the plural sample images.
Abstract:
A digital color copying machine includes, reading means for reading an original image to produce digital image data, area designating means for designating an area of the original image; memory means for storing the image data; writing means for writing the image data located on the specific area into the memory means, reading-out means for reading out the image data stored in the memory means; sheet size designating means, and size setting means for setting the size of the unit image to be printed on the copying sheet. The image data of a partial or entire portion of an original are once stored in the memory and repeatedly read out, whereby a plurality of the same images can be formed on a plurality of portions of a copying sheet, and the number and direction of the images to be formed can be designated monitoring the display thereof.
Abstract:
A digital color copying machine comprising a test mode is disclosed. In the test mode, image data corresponding to a partial area of an original document indicated is stored in a RAM, and thereafter, the image data stored in the RAM is read out repeatedly plural times of a number input by a set of ten keys, and plural test images of the input number for which the color correction is made with different color balances respectively are formed as mosaic monitor images on a recording medium. Then, one of plural test images is selected, and a copy of document having a color balance of the selected test image is produced.
Abstract:
A digital color copying machine provides for setting a specific area of an original document and storing image data of the specific area with respect to gradation of color of the original document. The color of the image data contained in the image memory can be compensated by iteration of the color image forming process. A plurality of images, each having a differently compensated color can be provided in different positions on one of the copy sheets as transferred from the original document.
Abstract:
A recording system is equipped with a pre-processing device which serves as an image recording unit for recording an image on sound paper based on image data, and a post-processing device which serves as a sound data recording unit for recording sound data related to the image data on the sound paper.
Abstract:
An image forming system, for preventing forgery of paper money, a check, securities or the like, having a plurality of copying apparatuses, and a controller, for controlling each of the copying apparatuses, connected with them through a communication line. The copying apparatus includes a reader which reads an image as of the paper money, etc. and which outputs image data corresponding to the image; a printer for printing the image read by the reader on paper; a first transmitter for transmitting the image data to the controller through the communication line; and a prohibiting device for prohibiting an operation of the printer. A signal, which prohibits copying, is transmitted from the controller to the copying apparatus. The controller includes a deciding device for deciding whether or not the data received from the copying apparatus corresponds to an image which is prohibited from being copied; and a second transmitter for transmitting the signal which prohibits copying to the copying apparatus through the communication line, if the deciding device decides that the data received from the copying apparatus corresponds to the image which is prohibited from being copied.
Abstract:
A microfilm reader printer which includes a photo detector provided in a light path from a light source to a projecting surface, a control arrangement for setting quantity of light on the projecting surface to a predetermined value in accordance with an output of the photo detector, and an arrangement for compensating an error between change in output of the photo detector and change in quantity of light on the projecting surface in response to changeover of the projection magnification, in accordance with the changed projection magnification. By the above arrangement, the quantity of light on the projecting surface is maintained at the predetermined constant value regardless of the changeover of the projection magnification.
