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.

Recording system and recording method for recording sound and images on sound paper

A facsimile device having a copy mode includes an image reader and a recording device and forms an image with the recording device based on a received signal from a communication network or a read signal from the image reader. In the copy mode, data processing of the read image is performed in accordance with the resolution and half tone expression characteristic of the image reader and the recording device. In a facsimile mode, data processing of the image is performed with a reproduction characteristic according to the half tone and text images.

Facsimile device capable of properly recording halftone image and text image

In the electronic sort of a digital copying machine, image data of a document consisting of a plurality of sheets are read and compressed to bi-level data in a memory. The compressed image data are recovered to multi-level data successively. When a plurality of copies of the document are produced, the recovery action is repeated by the number of the copies. In a facsimile machine combined with a digital copying machine, bi-level image data for the automatic reduction transmission are recovered first to multi-level image data, and the density of the multi-level image data is changed for the reduction. Then, the multi-level data are converted to bi-level data for facsimile transmission. In a digital two-color copying machine, multi-level image data of the second color of the two colors to be recorded later has to be synchronized to those of the other in correspondence to the delay of the recording time between the two colors. Then, the multi-level image data of the second color are converted to bi-level data in a delay memory in real time, and the bi-level data are read later from the delay memory and recovered to multi-level data.

Image forming apparatus wherein data is converted between multi-level

In a shadow process mode, a scanner reads out an original with a first exposure lamp in a first scanning operation. The readout image data is stored in an image memory via an I/O control unit. In the second scanning operation, the scanner reads out the original with a second exposure lamp having an illumination direction different from that of the first exposure lamp. The image data read out in the second scanning operation and the data stored in the image memory are subtracted for each pixel by a subtractor. The difference thereof is compared with a predetermined value in a comparator. The compared result is output to a selector, whereby a desired image data is provided to a printer processing unit via the I/O control unit.

Image forming apparatus having illumination direction altered for every

In an image processor, a scramble device performs scramble processing to deform a document image by using scramble conditions by rearranging pixel data in the document image read by a reader. The scramble conditions are embedded in a hard copy of the document image subjected to the scramble processing in such a way that the scramble conditions cannot be easily seen by the naked eye. Thus, the scramble conditions are included in the hard copy. The hard copy is reproduced by using the scramble conditions restored from the hard copy. If a user desires, the scramble processing is performed not on a front page, but on the following pages. The scramble processing can be performed at different levels, and the scramble conditions include a level of scramble processing. Preferably, special marks can be registered, and a level of scramble processing is also registered for each of the marks. If one of the special marks are extracted from a document image, the repetition time is determined automatically according to the registered data.

Imaging processor

The facsimile machine according to the invention can set a so-called night time collective time designation mode for power saving during night time processing time. Turning on a prescribed operation key of the facsimile machine permits printing. More specifically, even when the machine is in the power saving state, a printing operation is permitted in response to a key input.

Facsimile machine capable of distinguishing copied image and received

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.

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.

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 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.
