Abstract: A wireless mode between a scanner and an image communication apparatus is changed, in response to completion of image transmission from the scanner to the image communication apparatus, completion of print of the image sent from the scanner to the image communication apparatus, completion of transmission via a communication line connected to the image communication apparatus of the image sent from the scanner to the image communication apparatus, instructions to stop print of the image sent from the scanner to the image communication apparatus, instructions to stop transmission via the communication line connected to the image communication apparatus of the image sent from the scanner to the image communication apparatus, and states of the scanner and the image communication apparatus at a predetermined time and so on. For example, a low power consumption mode and communication mode of Bluetooth communication are switched to each other.

Abstract: Data communicated on one wireless channel is converted and communicated via a wired line. Alternatively, data communicated on a plurality of wireless channels is bundled and communicated via a wired line using a number of channels smaller than that of the wireless channels. In a case where another wireless communication apparatus wishes to use a wireless communication channel when a plurality of wireless channels are being used for communication, some of the plurality of wireless channels are released, thereby making it possible for the other communication apparatus to perform communication even when communication is being carried out using the plurality of wireless channels. When communication by the other wireless communication apparatus subsequently ends, communication on the original number of wireless channels is resumed.

Abstract: A radio communication apparatus capable of executing communication and processing of audio data and image data by simplifying the system structure where various apparatuses are connected via a terminal adapter (TA), which conventionally used a large area and whose connection was complicated. More specifically, the system structure comprises: an interface unit (RS232C controller 219, driver 220, PIAFS controller 228, I.460 processor 236) connected with a data terminal (PC) by radio or by cable; radio communication unit (PHS engine unit 237) for realizing radio communication with a wireless telephone unit; and transmission arrangement (first port switch 229, second port switch 233, ISDN interface unit 225 and the like) for transmitting at least one of the data transmitted by the data terminal (PC) or the audio data transmitted by the wireless telephone unit, to the digital public communication line (ISDN).

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: 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: 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: A data communication apparatus and an electronic mail data producing method are provided that are capable of allowing a file name to be easily added to a file attached to an electronic mail and also allowing a file name to be added to a file attached to an electronic mail, which is commensurate with the contents of the date to be transmitted. A CPU of the data communication apparatus combines a page number allotted to each of the images converted into files with the subject of the electronic mail that is inputted, to generate an attached image file name, and transmits the electronic mail with the image data in the form of files attached thereto together with the generated attached image file names. Therefore, it is not necessary to input the name of an image file attached to an electronic mail, which facilitates the operation of transmitting an electronic mail and enables giving a file name that enables the receiver of the electronic mail to easily recognize the contents of the attached image file.

Abstract: An image processing apparatus and method is provided that enables the output of image data in a size suitable for a transmission method that is employed. If electronic mail data is transmitted by electronic mail, a CPU of the image processing apparatus converts read image data into an electronic image file while changing the width thereof according to a predetermined reading image width set by a scanner and transmits the image file as electronic mail data. If electronic image data is transmitted by color facsimile, the CPU provides control such that white pixels are added to the electronic mail data so that the width thereof can be equal to a predetermined image width. By thus changing the width of an image file to be transmitted as an attachment to an electronic mail according to a predetermined image width, an image properly laid out in a proper size can be reproduced at a facsimile receiving side and there is no unnecessary area when the image file is opened at the electronic mail receiving side.

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: 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: 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: 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 communicating apparatus which accommodates a plurality of channels, 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, a message of a sender can be recorded. The apparatus has means for detecting a specified signal such as a tone signal like DTMF or the like which is transmitted from the sender upon call transfer and means for, when the specified signal is received, suspending the transfer and storing a message of the sender into the communicating apparatus by a message recording function of the communicating apparatus.
