Abstract: A data managing device according to the present invention processes the same object pixel before and after variable magnification processing, and collectively manages processing data before and after the variable magnification processing by making access to a memory once. In the variable magnification processing before and after which the number of object pixels differs, 1-bit BF data for area separation processing performed before the variable magnification processing and 7-bit produced error data for error diffusion processing performed after the variable magnification processing are mixed, and data composed of a total of 8 bits which is obtained by the mixing is read out/written from and to the same address in a SRAM 4 at the same access timing. Therefore, at the time of reduction processing, a reduction processing control signal SMWAIT is produced, and error diffusion processing is stopped when the signal is at a high level.

Abstract: A facsimile system having a capability to selectively retransmit transmitted and received facsimile signals to an archive station. A facsimile system including a scanner, printer, modem and memory for storing a speed dial directory, documents storage, and system parameters is controlled to transmit and receive facsimile signals and to selectively retransmit such signals to an archive station. As remote stations identified in the speed dial directory are those stations for which it is likely communications need not be archived, entries in the speed dial directory include a field for an exception tag. Prior to retransmission to the archive station the phone number of the remote station is tested against the phone numbers in the speed dial directory and if that number is found in the directory, and is tagged, the facsimile signal transmitted to, or received from, that remote station is not archived.

Abstract: An imaging and recording apparatus for electrically recording an optical image of a subject as an image information signal which facilitates memory access from an external device and prevents image information from being changed. Upon manipulation of a recording trigger switch, an image outputted from a camera signal processing circuit at that time is written into a semiconductor memory, then subjected to data compression in a data compression circuit, and stored in a semiconductor memory. It is now assumed that an external device not illustrated is connected to a connector and this external device orders taking in the image of the semiconductor memory. If at this time the semiconductor memory is writing an image, a state detection circuit detects the fact and inhibits the external device from taking in the image. Furthermore, while the external device is taking in the image of the semiconductor memory, the state detection circuit detects this fact.

A timer is provided for outputting a time and a time range register registers a heater-on time range. A heater-on managing unit controls the heater control unit so that the heater is at a preheat temperature level within the heater-on time range, and so that the heater is at an image fixing temperature level when an image signal is received. Further, a heater-off managing unit controls the heater control unit so that the heater is at the image fixing temperature level out of the heater-on time range when the image signal is received. The heater-on managing unit can also shift a beginning time of the heater-on time range from a registered time to a time of a receipt of the image signal, so to extend the ending time of the heater-on time range when the image signal is received within the heater-on time range.

Abstract: A facsimile apparatus comprises a receiving buffer for receiving video data, a scanner for reading an image, a VRAM for storing a coded data, a single coding/decoding (C/D) IC for MR-coding, MR-to-MMR coding, decoding, and error-checking, and a page printer, and a control circuit, when an event requiring more than two operations of the C/D IC at the same time, the control circuit permits only one operation and force the other operations to wait in some condition. In another condition, the control circuit permits one of the other operation and force the other operations to wait. For example, when the scanner reads an image to produce read data and the C/D IC codes the read data to store the read data in the VRAM and there is a call, the control means connects the line but keeps the coding if the receiving buffer has a space. In the presence of the space the control circuit interrupt the coding and starts the decoding.

Abstract: Efficient image transmission is performed upon determining, based upon information sent from a receiving side at the time of negotiation, whether the apparatus on the receiving side is capable of progressive build-up, pseudo-progressive build-up in stripe units, sequential build-up or more than one of these build-up methods. Examples of the information sent from the receiving side include an instruction entered on the receiving side, the type of printer, the stripe width if the printer is capable of stripe printing, the communication speed and the memory capacity, etc. It is possible to use information from a line or network as well. This arrangement makes it possible to transmit image data that has been coded efficiently. Outstanding effects are obtained in multiple-address communication.

Abstract: A facsimile apparatus includes a memory and a printer. The memory stores images which are sequentially received from a first page. The printer sequentially reads out the images stored in the memory from the last page to record the read out images on sheets when the images for one communication can be stored in the memory. Also, the printer sequentially reads out the images stored in the memory from the first page and records the read out images on sheets to eject the recorded sheets with a faceup state when the images for one communication can not be stored in the memory.

Abstract: Storage, manipulation, and retrieval of files, for example data representations of scanned documents, is facilitated by establishing a relationship between an arbitrary, image domain file label and a computer recognizable text domain file name for the file. Selection of the arbitrary, image domain file label is interpreted as a selection of the related file. The arbitrary, image domain file name is assigned by way of a paper form or the like, and may be assigned at the time of document storage. The arbitrary, image domain file label facilitates the meaningful naming of a file for storage when a keyboard or other typical text entry apparatus is unavailable, such as when inputting a document for storage by way of a facsimile machine. Character recognition is not performed on the arbitrary, image domain file label, so the burden on the processing resource is minimized, while errors from inaccuracy are eliminated.

Abstract: In a facsimile system received data is initially stored in an internal storage device, and subsequently is stored in an external storage device (hard disk drive or floppy disk drive) by a transfer process. The facsimile system stores the received data from a transmitting party in the internal storage device and determines a state of availability of the external storage device. When the external storage deice is available, the received data is transferred to the external storage device, and if not available, transfer is delayed until it becomes available.

Abstract: An image of an object, such as message for facsimile transmission, is acquired optically by setting photosensitive cells along a multiplicity of rows and columns of a random access memory to a given value such as 1, exposing the plurality of cells to an image so the cells change electrical values to exposure values, and after a given time, ending the effective exposure by maintaining values in the cells corresponding to the exposure content of the cells. The maintaining involves going in sequence from row to row, and in each row simultaneously reading the cells in the row and, on the basis of the reading, writing refresh values representative of the exposure values back into the read cells of the row, and repeating the row to row sequence cyclically to prevent changes in the cells due to further exposure. The refreshed data is processed by sequentially reading the refresh values of the cells of a column serially from column to column until all the values have been processed.

Abstract: A facsimile apparatus, copier, or other image processing apparatus superior in handling of paperless documents and able to store a large volume of image data, using as a means of storing the image data a small-sized, interchangeable optical disk storage medium known as a "mini-disk". In the case of a facsimile apparatus, a document reader reads the content of the document for transmission as image data, a signal processor compresses the image data and stores it on an optical disk cassette through an optical disk drive. The image compressed data stored in the optical disk cassette may be immediately sent to the destination facsimile apparatus through a modem and line controller or may be sent at a date and time designated for preset transmission. Further, the image data received through the line controller and modem may be printed by a printer or stored in an optical disk cassette.

Abstract: A facsimile unit has an image memory which can be used as a printing memory for storing received print image data for printing and as a communication memory for storing both part of the print image data and coded image data to be transmitted and/or coded image data of backup reception, instead of being used solely for image bitmap development for printing. The allocation proportion of the image memory between the printing memory portion and the communication memory portion can be arbitrarily set by the user depending on the usage. A memory device having a fixed capacity is then used efficiently and the cost of the facsimile unit is reduced.

Abstract: A raster scanable number is representative of a number of raster scans that can be performed with dot image data stored in a print image buffer. A raster scanned number is representative of a number of raster scans actually performed by a print mechanism. The raster scanable number and the raster scanned number are compared to detect an occurrence of a print overrun. When the print overrun is detected, the data processing load imposed when compressed print data received from an external unit is decoded is calculated, and the storage capacity of the print image buffer is expanded to a degree determined according to the data processing load thus calculated. Therefore, even when the data processing load is large, such as during encoding processes, so that dot image data developing processes are delayed, the print image buffers will not be emptied of dot image data for printing and printer overrun can be prevented to a very high level.

Abstract: In transmitting enciphered data, to enable an ECM communication, whether a cipher communication is performed or not can be decided according to an available memory capacity. To perform the cipher communication, whether the available capacity of a RAM 4 is sufficient for one frame or not is determined. When the available capacity X.sub.0 of the RAM 4 is larger than a memory capacity X necessary for the cipher communication according to an ECM communications method, the cipher communication is executed. When the available capacity X.sub.0 of the RAM 4 is smaller than the memory capacity X necessary for the cipher communication according to the ECM communications method, it is determined that the cipher communication is impossible, and the communications mode is changed to the normal transmission according to the G3 communication.

Abstract: An image communication apparatus enhances the likelihood of successful communication with a destination station without conflict with business of other users who use the same apparatus. In the image transmission, existence of a connection with the destination station is determined after the dialing of the destination station, and if the connection fails, redialing is performed. A remaining capacity of a memory for image to be transmitted is determined, and the redialing is repeated without regard to a preset limit on the number of times of redialing, if the remaining memory capacity is sufficiently large, while redialing is performed only the preset number of times if the remaining memory capacity is not sufficiently large.

Abstract: A signal receiving unit receives an image signal through the facsimile function. An image reading unit reads an image and outputs the corresponding image signal.

A storing unit stores the signal input by the signal receiving unit if appropriate. A switching unit switches so that the outputting unit starts outputting of the image specified by the signal output by the image reading unit when the image reading unit starts reading of the image even if the outputting unit is outputting the image specified by the signal receiving unit, the storing unit then storing the signal input by the signal receiving unit while the relevant signal is not used by the outputting unit using the signal being output from the image reading unit.

Abstract: In a video printer, to delete a frame of video data stored in a frame memory, mute data is written in the frame memory over previously written video data by operating a memory delete key. Thereby, a mute image is displayed on a monitor. To delete one of a matrix of sub-frames of a multi-frame image, the sub-frame to be deleted is designated prior to operating the memory delete key, so that mute data is written in a corresponding location of the frame memory. Thereby, an image containing a blank in at least one sub-frame may be printed out.

Abstract: An image sensing operation control device has an electro-developing recording medium to electronically develop an image formed by a photographing lens.

One of the front and back side images is compressed and transferred to a SCSI bus, and the other is temporarily stored in a graphic video RAM and can be displayed or printed. After the former image is completely compressed and transferred, the latter is read from the video RAM, compressed by the compression circuit and then transferred to the SCSI bus.

Abstract: The present invention is method and apparatus for preventing overflow and underflow of an encoder buffer in a video compression system. A virtual buffer is created in a rate controller to model the decoder buffer fullness (102). A sequence of bits is generated by an encoder (104). The encoder is controlled by the rate controller to prevent a decoder buffer underflow and overflow. Then, the sequence of bits is received by the encoder buffer to produce a bitstream (106). The bitstream corresponds to an instantaneous channel bitrate. The bitstream is transmitted from the encoder buffer to a decoder buffer following a delay (108). The delay is controlled by a rate controller to synchronize an encoder buffer fullness with a virtual buffer fullness (110). The synchronization prevents overflow and underflow of the encoder buffer.

Abstract: An image data processing apparatus for dividing one page of image data into segments for high-speed image data processing. Each of the image data segments is processed by a separate compandor. The processed data is stored in an FIFO memory corresponding to each of the compandors matching the segments. The data stored in the FIFO memory is moved from there to a compressed data storage by DMA data transfer under control of a DMA data transfer controller. The DMA data transfer controller, activated beforehand by a CPU, starts transferring data upon receipt of a DMA data transfer request signal DRQ generated by a DRQ control circuit corresponding to each FIFO memory. Since the DMA data transfer controller is already operational, it executes data transfers in a very short time on receiving the DMA data transfer request signal.

Abstract: An image input terminal synchronously transfers image data to a host terminal when the internal data transfer rate of the image input terminal exceeds the data transfer rate of the host terminal. The image input terminal scans the document at a constant rate, but the constant rate is slower than the normal scan rate for the image input terminal, thereby effectively scanning the document at a higher resolution. To realize an apparent internal data transfer rate equal to the data transfer rate of the host terminal, the image input terminal periodically discards or skips scanlines of valid image data to give the host terminal ample time to complete the transfer of valid image data. The image input terminal, to facilitate a synchronous transfer of image data, will skip N-1 scanlines of valid image data out of N scanlines of valid image data such that N is determined by the data transfer rate of the host terminal.

In the image forming device, an information input unit writes some information identifying the copying machine to an area in an information storing unit at the time when a power source is turned on for the copying machine for the first time after the assembly thereof. When the power source is turned on for a second and any subsequent times for the copying machine, the copying machine copies an original sheet in such a state of the machine that the information stored in the area of the information storing unit is added to the output image in the form of a pursuit image which it is hard or impossible to recognize with the human eyes.

Abstract: An image processing system, such as a facsimile system, in which a source transmits information to a receiver. The information includes an identification signal which indicates whether image data or an extended program, such as a diagnostic program, is to follow. If image data follows, the receiver processes the data in a normal manner. If the diagnostic program follows, it is stored in a memory for subsequent execution. Since the program doesn't have to be stored in the memory at all times, the memory is used more efficiently. The receiver may request transmission of the diagnostic program in the event of a system failure. The source may transmit a starting time for execution of the diagnostic program.

Abstract: Main scanning is performed by reciprocating a recording head having plural of recording elements. After the main scanning is completed, sub-scanning is performed by conveying the recording paper for a distance corresponding to the recording width of the recording head to record an image corresponding to received image data on the recording paper. At this time, the minimum transmission time for data is set in correspondence with the recording speed of the set recording mode. For example, a decision is made as to whether a one-direction recording mode or a bidirectional recording mode is set, and when the one-direction recording mode is set, the minimum transmission time for data is set to a time longer than that set in the bidirectional recording mode. This prevents overflow of memory for storing the received image data.

Abstract: In a facsimile apparatus, an image to be transmitted is stored in a first memory and the stored image is transferred to and stored in a second memory, which is capable of being loaded to and unloaded from the facsimile apparatus. This processing is executed if certain conditions such as time are satisfied, and if the second memory has been loaded. After the transfer of the image data, the status of storage in each of the first and second memories is managed. In a case where the transmitted image that has been stored in the second memory is to be transferred to the first memory, a necessary condition is that the image stored in the loaded second memory coincide with the contents of the managed status of storage.

Abstract: Print image data produced by external equipment such as a personal computer is temporarily stored in a page buffer of an IOCP. The print image data stored in the page buffer is divided into a plurality of parts so that each divisional part can be transferred to another page buffer of a main control circuit within a scan return period of a scanner. Image data to be transferred to the page buffer of the main control circuit is selected by a multiplexer between the print image data and copy image data from the scanner. Thus, the print image data and copy image data is processed by an image processing system in a parallel manner.

Abstract: In this facsimile machine, it is determined whether data to be stored in a RAM is image data, and, if the data is image data, a normal cluster for writing the image data into is ensured. If the data is not image data, a defective cluster is selected, and the data is written into the defective cluster. In this case, if no defective cluster is selected, a normal cluster is selected, and the data is written into the normal cluster. Upon termination of the data writing operation, the data is managed on a classification (kind) basis. Accordingly, a facsimile machine is provided that is low in price and can easily carry out individual management for preservation of data while maintaining preservation (storage) quality of data even when a semiconductor memory that is not guaranteed in quality is used as the storage medium for the data.
