Digital photo frame device

A digital photo frame device, comprising:

• a buffer unit for temporarily storing TV signals to be displayed or processed;
• a compression/decompression engine coupled to the buffer unit for compressing TV signals in the buffer unit into an image file or decompressing an image file into TV signals;
• a video processor for displaying the TV signals temporarily stored in the buffer unit on a display unit;
• an external storage device pre-saved with data representing various clock background patterns;
• an interface unit coupled to the buffer unit to write data from the buffer unit to the external storage device or data from the external storage device to the buffer unit;
• and
• an OSD clock display unit for recording the current time and storing at least an OSD time pattern in advance;
• wherein the clock background pattern pre-saved in the external storage device is written to the buffer unit by means of the interface unit so as to be displayed, and
• wherein the OSD clock display unit determines a real-time clock pattern to be displayed and a position of the display according to the recorded current time and the corresponding OSD time pattern selected when the video processor displays the clock background pattern so that the clock background pattern and the real-time clock pattern overlying over the clock background pattern are displayed on the video display in an OSD fashion.
