Digital imaging apparatus and control method thereof

A digital imaging apparatus comprising:

• a body comprising;
• a display unit configured to output an image signal as an image;
• a Motion Joint Photographic Experts Group (MJPEG) decoder;
• and
• an image encoder configured to generate an encoded signal;
• an image processor configured to generate the image signal;
• and
• a communicator configured to transmit data to and receive data from an outside apparatus;
• a user input unit comprising an image input unit configured to generate an outside image signal that corresponds to an outside image, and an MJPEG encoder configured to compress the outside image signal into an MJPEG compressed outside image signal;
• and
• a data interface configured to receive the MJPEG compressed outside image signal, and transmit the MJPEG compressed outside image signal to the MJPEG decoder,
• wherein the MJPEG decoder is configured to decode the MJPEG compressed outside image signal received from the data interface into a decoded outside image signal,
• the display is further configured to output the image signal based on the decoded outside image signal, and
• the image encoder is further configured to generate the encoded signal based on the outside image signal, and transmit the encoded signal to the communicator in a predetermined format.

A method of controlling a digital imaging apparatus, the method comprising:

• generating by a user input unit an outside image signal corresponding to an outside image;
• transmitting the generated outside image signal to a body of the digital imaging apparatus through a data interface in a form that is not encoded or compressed;
• receiving at the body the outside image signal transmitted through the data interface;
• recognizing a user based on the outside image signal that is not encoded or compressed;
• executing an application of the digital imaging apparatus based on a result of the recognizing;
• displaying an image based on the outside image signal that is not encoded or compressed;
• compressing the outside image signal into a compressed outside image signal;
• and
• transmitting the compressed outside image signal to an outside apparatus.

A method of controlling a digital imaging apparatus, the method comprising:

• generating by an user input unit an outside image signal corresponding to an outside image;
• compressing the outside image signal by using a Motion Joint Photographic Experts Group (MJPEG) encoder into an MJPEG compressed outside image signal;
• transmitting the MJPEG compressed outside image signal to a body of the digital imaging apparatus through a data interface;
• receiving at the body the MJPEG compressed outside image signal transmitted through the data interface and decoding the MJPEG compressed outside image signal by using an MJPEG decoder into a decoded outside image signal;
• recognizing a user based on the decoded outside image signal, and executing an application of the digital imaging apparatus based on a result of the recognizing;
• displaying an image based on the decoded outside image signal;
• compressing the decoded outside image signal into a compressed outside image signal;
• and
• transmitting the compressed outside image signal to an outside apparatus.

An imaging apparatus comprising:

• an image photographing device configured to photograph an outside image and generate an outside image signal corresponding to the outside image;
• a data interface configured to receive the outside image signal from the image photographing device and to transmit the outside image signal to the body;
• and
• a body comprising;
• a display unit configured to receive the outside image signal from the data interface and output the image signal in the form of an image;
• an image encoder configured to receive the outside image signal from the data interface and compress the outside image signal into an encoded signal;
• and
• a communicator configured to transmit the encoded signal to an outside apparatus.
