Abstract: Disclosed are a communication apparatus capable of efficiently using a communication line, a control method of the communication apparatus, a facsimile apparatus, a communication method, and a program. To accomplish this, if “print later” in a menu is selected with an image displayed during data communication while a line is connected (S432), printing data is generated from an HTML file of the displayed image (S433). That is, the displayed image is designated as an image to be printed after the line is disconnected. The generated printing data is stored in a printing data buffer (S434). If the presence of the data in the printing buffer is detected (S437) after the line is disconnected (S436), the data is printed (S438).

Abstract: In a communicating apparatus which makes speech and image communication, a proper communication path is selected by a simple construction of a low cost, thereby enabling data communication of a high-speed and high reliability to be performed. If a telephone number of an opponent station corresponds to an VoIP network, a communicating apparatus obtains an IP address of the opponent station from an SIP proxy server and sends and receives communication data on an IP network to/from the opponent station by a file sending/receiving protocol such as FTP, HTTP, or the like.

Abstract: A communication apparatus includes a register for registering a facsimile number of a sending destination for an abbreviation number, a register for registering an electronic mail address of the sending destination for the same abbreviation number, a key corresponding to the abbreviation number, a key representing facsimile sending, and a key representing electronic mail sending, a unit for executing the facsimile sending of a read image to the registered facsimile number when the key representing the facsimile sending is depressed pursuant to depression of the key corresponding to the abbreviation number, and a unit for executing the electronic mail sending of the read image to the registered electronic mail address when the key representing the electronic mail sending is depressed pursuant to depression of the key corresponding to the abbreviation number, so that it is possible to reduce the number of necessary keys.

Abstract: To provide an communication apparatus such as a facsimile apparatus that allows radio communication in different modes to be used so that efficient communication can be implemented. For instance, even in a state where the image reading section (hand scanner) is removed, it allows an image read by the facsimile apparatus to be sent to another first terminal and simultaneously radio-communicated to a public switched line by a second terminal by way of the facsimile apparatus. Also, it allows a quality cordless telephone function to be implemented by a TDMA radio line and simultaneously high-speed transmission of image data and so on to be implemented by a frequency hopping radio line.

Abstract: In a communication apparatus corresponding to an analog communication path of a voice band and a network communication path, high-speed and high-reliability data communication are performed by selecting an appropriate communication path without troublesome user operation. A communication apparatus which performs IP communication and analog communication via an ADSL gateway obtains the IP address of a destination station from an SIP proxy server and transmits/receives communication data to/from the destination station on an IP network by a file transmit/receive protocol such as FTP, HTTP or the like, when the telephone number of the destination station corresponds to a VoIP network. The apparatus performs analog facsimile communication on a line switching network when the telephone number of the destination station does not correspond to the VoIP network.

Abstract: In a communication apparatus corresponding to a voice-band analog communication path and a network communication path, high-speed and high-reliability data communication is achieved by selecting the appropriate communication path without any complicated user operation. The communication apparatus which performs IP communication and analog communication through an ADSL gateway obtains a communication partner IP address from an SIP proxy when a communication partner telephone number corresponds to a VoIP network, and transmits/receives communication data to/from the communication partner on an IP network based on a file transmission/reception protocol such as FTP, HTTP, or the like.

Abstract: A communication apparatus automatically sets the most appropriate communication mode in accordance with the location at which the communication apparatus is used. For example, the communication mode is switched between operating as a master station and operating as a remote station of a wireless communication system depending on whether or not connection is made to a wired communication line.

Abstract: Color facsimile communication uses image data obtained by JPEG-compressing data having a CIE Lab color space. To attach a JPEG image to e-mail, image data obtained by JPEG-compressing data having an Internet standard YCbCr color space is desirable. When an image transmission method is selected, color space conversion (conversion to a CIE Lab or YCbCr color space) corresponding to the selected transmission method (facsimile transmission or transmission by attaching to e-mail) is performed for an image to be transmitted. This image subjected to the color space conversion is encoded by JPEG, and the encoded image is transmitted by the selected transmission method.

Abstract: This invention solves various problems associated with apparatus registration and communications after registration in an n:n communication system based on, e.g., a Bluetooth protocol. Information of a newly registered wireless communication apparatus is sent to already registered wireless communication apparatuses. A communication with the already registered apparatus starts by sending a Page message based on the Bluetooth protocol. When an apparatus that output a registration request in response to an Inquiry message based on the Bluetooth protocol is selected, identification information of the selected apparatus is stored. Upon registration, already registered apparatuses are not displayed.

Abstract: An image communicating apparatus determines whether or not the amount of compressed image data is a predetermined amount or greater when transmitting a scanned color image as attached data in an e-mail message. If the amount of data is the predetermined amount or greater, the compressed image data is decompressed, and the image data is again compressed with a lower resolution, thereby reducing the amount of data to less than the predetermined amount. The image data is then attached to an e-mail message, and the e-mail message is transmitted.

Abstract: In a communication system using frequency hopping to transmit data packets, a transmission request from a transmitter is transmitted through a first control channel. The transmission request includes a frequency channel designation selecting one of plural data channels. A receiver that receives the transmission request sends a receive confirmation through a second control channel and the data packets are then transmitted through the data channels so that the data channel is changed each time a data packet is transmitted.

Abstract: In a communicating apparatus which accommodates a plurality of channels, a message from a sender can be recorded even if a transfer station is busy (a telephone is being employed) or is located at a place where a radio wave does not reach. The communicating apparatus is able to detect a specified signal, such as a tone signal like DTMF or the like, which is transmitted from the sender upon a call transfer. When the specified signal is received, the communication apparatus suspends the transfer of the call and stores a message from the sender using a message recording function of the communicating apparatus.
