Digital image viewing system, a cellar phone and a digital photo frame

A digital image viewing system including a digital image display device capable of charging a rechargeable battery of a cellar phone through a first wired path and receiving digital image data transmitted from the cellar phone through a second wired path to display the received digital image data,

• wherein the digital image display device comprises:
• a power supply;
• a display side power supply contact for the first wired path to charge the rechargeable battery of the cellar phone by means of the power supply, the display side power supply contact being combined with a display side communication contact for the second wired path to receive the digital image data transmitted from the cellar phone;
• a display side memory of digital image data, the digital image data including the digital image data transmitted from the cellar phone through the display side communication contact;
• a digital display that displays image on the basis of the digital image data stored in the memory;
• and
• wherein the cellar phone comprises:
• the rechargeable battery to be charged by the digital image display through the first wired path;
• a phone side memory that store digital image data;
• a phone side power supply contact for the first wired path to charge the rechargeable battery by means of the digital image display device, the phone side power supply contact being combined with a phone side communication contact for the second wired path to transmit the digital image data of the phone side memory to the digital image display device, wherein the second wired path for the digital image transmission is simultaneously formed when the first wired path for the battery charging is formed;
• and
• a controller that allows the digital image data in the phone side memory to be transmitted to the digital image display if the digital image display is admitted to receive the digital image data and the second wired path is formed, and not to allow the digital image data in the phone side memory to be transmitted to the digital image display if the digital image display is not admitted to receive the digital image data even if the second wired path is formed, wherein the charging of the rechargeable battery of the cellar phone from the digital image display is allowed when the first wired path is formed regardless of whether or not the digital image display is admitted to receive the digital image data through the second wired path.
