A video telephone including a display unit and a handset for transmitting and receiving both audio signals and digital data representative of video images over an established communication channel across a conventional telephone line. The display unit includes a receiver for receiving signals from the handset and a display screen for displaying a video image. A microprocessor is connected to the receiver and the display unit. A data storage device for storing data representative of an image and a digital camera for capturing a digital image are also connected to the microprocessor. The digital camera transmits the captured digital image to the microprocessor. The video telephone is operable between a first not-in-use mode in which the microprocessor reads data stored in the data storage device and displays the image represented by the data on the display unit and a second in-use mode in which the microprocessor receives the digital data representative of the captured image from the digital camera and the digital data received over the established communication channel for display of both the digital data representative of the captured image from the digital camera and the digital data received over the established communication channel on the display unit simultaneously. The handset includes a power switch for generating a control signal for switching said video telephone between said first and second modes and a transmitter for transmitting said control signal to said display unit.
