Demand for an inexpensive color facsimile apparatus is expected not in the business field but in home use, and a product which is easy to operate and use is required in consideration of home use. Such color facsimile apparatus, i.e., an image communication apparatus has a communication means for communicating with a partner terminal via a line, a DRAM ( ) for storing image information received by the communication means, a management means for managing the image information stored in the DRAM ( ), decoding means for decoding the image information stored in the DRAM ( ) into image data to be recorded on a recording paper sheet, and a recording unit ( ) for recording a visible image on a recording paper sheet on the basis of the decoded image data using a selected attached ink cartridge. A CPU ( ) of the image communication apparatus counts C indicating the number of non-recorded color images stored in the DRAM ( ), M indicating the number of non-recorded monochrome images, C indicating the number of recorded color images, and M indicating the number of recorded monochrome images. When a value C &plus;M is not zero, the CPU displays a message indicating that a new image is stored in the DRAM ( ) using a first display unit on a control panel ( ). When the value C is not zero, the CPU displays a message indicating that a new image is stored in the DRAM ( ) using a second display unit independent from the first display unit.

Image communication apparatus and its control method

Whether a call is placed after waiting for confirmation operation or without waiting for confirmation operation upon completion of speech recognition is selected. Data is initialized in the standby state, and upon instruction of speech recognition, speech recognition is done. The speech recognition result is displayed, and when a speech recognition key is operated without any confirmation operation, speech recognition is redone without setting the standby state.

Apparatus for making outgoing call

An image communication apparatus and a communication controlling method thereon, wherein in the case where image data having an attribute not specified by the ITU-T recommendation is transmitted, regardless of an attribute of image data to be transmitted, a reception command including a first image attribute specified by the ITU-T recommendation are sent out, and information including a second image attribute of image data to be transmitted is sent out in a phase transmitting the image data after the reception command is sent out. And when an image is transmitted with the second image attribute, a transmission takes place with a binary file transfer communication procedure following a first communication procedure specified by the ITU-T recommendation so that image data having an image attribute not standardized by the ITU-T recommendation can be transmitted.

Image communication apparatus and communication control method thereof

A recording apparatus which reduces consumption of ink by preventing unnecessary recovery operation during a printing job by an ink-jet method. First, the recording apparatus detects whether a recording mode is a black and white printing mode or color printing mode. Second, if the printing mode is the black and white printing mode, then the image recording is performed by using only nozzles for K(black), as well as an idle discharge operation is performed only on the nozzles for K. Whereas if the color printing mode is detected, then the image recording is performed by using all the nozzles for C(cyan), M(magenta), Y(yellow), and K(black), as well as the idle discharge operation is performed on all the nozzles.

Image recording method and apparatus

A facsimile apparatus includes a call control unit, a transmission control unit for performing communication with a distant partner apparatus, a unit, using the transmission control unit, for sending/receiving a plurality of pieces of password information of different types during the communication with the partner apparatus, the pieces of password information including password information of a scheme unique to a maker and password information of a standardized scheme for apparatuses capable of intercommunication, an input unit for inputting the plurality of pieces of password information, a recording unit for storing the plurality of pieces of password information, and a selecting unit for selectively controlling a password communication operation by the plurality of pieces of password information.

Facsimile apparatus using standardized and proprietary types of passwords

A communication system in which if the connection between a facsimile apparatus and a host computer such as a PC is confirmed, the facsimile apparatus obtains information on whether or not the host computer is in ready status, as operation information of the host computer. If the host computer is not connected to the facsimile apparatus or it does not in operable state, otherwise the host computer operates but it is in busy status, the facsimile apparatus changes a negotiation protocol between the facsimile apparatus and another facsimile apparatus as the communication destination.

Communication system capable of changing communication protocol

The facsimile apparatus of this invention performs recognition processing by storing image data received from a transmitting terminal and by decoding the image data stored. The image data received is relayed and transmitted to multiple destinations on the basis of the result of this recognition.

Facsimile apparatus

A facsimile apparatus receives and stores image data, receives a sub-address signal, and processes the stored image data using pre-stored processing corresponding to the received sub-address signal.

Facsimile apparatus for processing received image data according to

In recording a received image in an image communication apparatus, there is discriminated whether the received image is to be recorded as a color image or as a monochromatic image, then determined, according to the result of the discrimination, which of plural recording members is to be supplied, also the mutually different plural recording members are selectively supplied according to the determination, and the received image is recorded on thus supplied recording member. In this manner it is rendered possible to preferentially select an optimum recording member for monochromatic image recording and another for color image recording, thereby improving the image quality in case of color image recording and reducing the running cost in case of monochromatic image recording.

Data communicating apparatus for selectively recording color and

In the processing and transmission of an image, there is generated additional information relative to the transmitting apparatus or to the image signal to be transmitted, then an image signal representing an input binary image and an iamge relative to the additional information is binary encoded, or an input multi-value image signal is multi-value encoded, and the binary encoded image signal and the multi-value encoded image signal added with data relative to the additional information are selectively released. Also in the processing of a received image, a binary encoded image signal or a multi-value encoded image signal contained in the received image signal is decoded, also additional information relative to the received image signal is extracted from the multi-value encoded image signal, and there is selectively released a binary image containing an image according to the image signal obtained by decoding the binary encoded image signal and relating to the additional information relative to the received image signal, and an image containing a multi-value image according to the image signal obtained by decoding the multi-value encoded image signal and an image according to the extracted additional information. Such configuration provides an image communication apparatus capable of maintaining compatibility with a conventional monochromatic image communication apparatus and also adaptable to a color image without image quality deterioration in the associated character information.

Image communicating apparatus

In an image communication apparatus, in the recording of a received image, there is discriminated whether the received image is to be recorded as a color image or as a monochromatic image, and the number of color image frames and the number of monochromatic image frames, recorded or to be recorded, are separately counted. Also there is discriminated whether the image to be transmitted is a color image or a monochromatic image, and the number of color image frames and the number of monochromatic image frames, to be transmitted, are separately counted. Also displayed is the mode capable of color image transmission or the mode incapable of color image transmission, and, at the receiving side, there is displayed the presence or absence of color image producing ability. These features enable efficient handling of a mixed file containing color images and monochromatic images, and the operator can be assured of smooth operations.

In recording a received image in an image communication apparatus, there is discriminated whether the received image is to be recorded as a color image or as a monochromatic image, then determined is which of plural cartridges is to be used according to the result of discrimination, and the received image is recorded with thus determined cartridge. In the apparatus capable of color and monochromatic image recording, it is thus made possible to reduce the overall cost and the electric power consumption, and to facilitate the maintenance.

A plurality of manufacturer identifiers handlable by its own device are registered, and a manufacturer identifier included in a signal from a communicating station is one handlable by its own device, a code corresponding to the manufacturer identifier of the communication station is sent to the communicating station so that a special function adopted by the manufacturer can be compatibly used.
