Abstract

A telephone apparatus (10) comprises a stationary terminal (12) connected to a telephone line for transmitting and receiving analog data and/or digital data, and a handset (18) connected to exchange signals with the stationary terminal. The handset comprises an image sensor (32) adapted to capture images and connected to transmit image data to the stationary terminal in digital format, and a display (28) connected to receive video data from the stationary terminal in digital format and to display them in form of image.

Description

"Telephone apparatus"
The present invention relates to a telephone apparatus with functions of transmission and reception of digital data.
In the field of the mobile telephony, the exchange of short text messages (SMS) in digital technology by means of cellular telephones has become widespread.
In the field of the fixed telephony, desk telephones are already in use by which SMS messages can be sent and received by composing the text on the alphanumerical pad of the telephone and by reading the incoming messages on a display provided on the telephone.
In order to comply with the needs of the fixed telephony, which are intended to provide the same functions now offered by the mobile telephony of capturing and sending multimedia color images (MMS), as well as receiving them, by means of cellular telephones, a main object of the present invention is now to provide a telephone apparatus with functions of transmission and reception of multimedia data.
The above-mentioned object and other aims and advantages, which will better appear below, are achieved by a telephone apparatus having the features recited in claim 1, while the dependent claims state other advantageous features of the invention.
The invention will now be described in more detail with reference to a preferred, nonexclusive embodiment shown by way of non limiting example in the attached drawings, wherein:
Fig. 1 is a plan view of a telephone apparatus according to the invention;
Fig. 2 is a plan view similar to Fig. 1, showing the front side of a handset of the telephone apparatus;
Fig. 3 is the circuit diagram of a terminal of the telephone apparatus according to the invention;
Fig. 4 is the circuit diagram of the handset of the telephone apparatus according to the invention; With reference to the above-mentioned Figures, a telephone apparatus 10 comprises a stationary, terminal 12 provided with an alphanumerical pad 14 for dialing telephone numbers and SMS messages, as well as with further push buttons T for controlling the different functions of the telephone. The terminal is also provided with a display 16 adapted to display menus, incoming SMS messages and any other operational information. Telephone apparatus 10 is provided with a handset 18 comprising a microphone 22 and a speaker 24 and connected to terminal 12 by means of a multiwire cable 20.
According to this invention, an LCD color display 28, e.g. a 2-inch display in FSTN or TFT technology, is housed on the back side 26 of handset 18, and a color image sensor 32, e.g. a CCD or CMOS sensor, preferably with 640x480 pixel resolution, VGA standard and 2 lux brightness, is housed on its front side 30. Display 28 and sensor 32 can be turned on by a push button P on the back side of the handset.
With reference to Figs. 3 and 4, handset 18 is provided with a processor CPUc, which is connected to receive digital signals from image sensor 32 via an interface intCCD and a controller contrCCD, and to send digital signals to display 28 via a controller contrLCD and an interface intLCD. Processor CPUc and terminal 12 exchange digital signals via a five- wire, USB connection (USB in the Figures). The wires of the USB connection are integrated in cable 20 and are connected, within the handset, to an interface intUSBc connected to processor CPUc. Display 28, interface LCD and processor CPUc are powered by a switching power supply AL which is arranged within the handset and is supplied via the USB connection.
Microphone 22 and speaker 24 are connected to an audio interface INTaud which is connected to terminal 12 for transmitting and receiving analog data via four leads AUD that are integrated in cable 20. Audio interface INTaud is also connected to processor CPUc for recording and storing voice messages. The corresponding signals are previously digitalized by a conversion block CONV.
Terminal 12 comprises a processor CPUb controlled by pad 14 and display 16, and is powered by the supply mains via an external power supply Alest. The USB connection is connected to a modem MOD within terminal 12, via an interface intUSBb. Modem MOD is connected to processor CPUb and to a telephone line LT via a line interface intLIN. The audio signal from the four leads AUD is received by a telephone hybrid circuit FORCH which is connected to processor CPUb and to the telephone line via the interface intLIN.
The traditional operations, as well as the transmission and reception of SMS messages, are performed in a way similar to the known telephone apparatus. For the transmission of MMS multimedia data, such as images or short, digital movies, the user grasps the handset and points the sensor CCD towards the target to be captured. Such operation is easy to be performed due to the high flexibility of cable 20, which includes nine wires. The images captured by the sensor are transmitted in real time to color display 28 on the back side of the handset. Therefore, the operator can shoot any target around the terminal while constantly monitoring the display. Digitalized vocal messages are recorded by processor CPUc within the handset, as well as multimedia data which have been sent or received.
A preferred embodiment of the invention has been disclosed, but of course many changes may be made by a person skilled in the art, depending on the circumstances, within the scope of the inventive concept. For example, although in the preferred embodiment the digital signals between the handset and the terminal are exchanged via a USB connection, the person skilled in the art will appreciate that any other suitable communication protocol can be used.
