Alternatively, the sensing unit  20  is further configured for receiving other control signal from a remote control (not shown in the figure) and then transmitting the other control signal to the signal processing module  12 . 
         [0016]    Shown in  FIG. 2A , the signal processing module  12  includes, but not limit to, a processing unit of internet connected digital information  122 , a timing unit  123  (T-COM) and a remote control unit  124 . In the embodiment, the processing unit of internet connected digital information  122  is configured for operating, identifying, decoding and transforming internet connected digital information to data in a displayable format, such as TIF, PNG, JPG, BMP or GIG format. In the embodiment, the internet connected digital information may be an internet digital content or contents provided by the web service of Web log, RSS or SNS. The timing unit  123  is configured for time preset to enable the internet connected digital photo frame to transmit or access the internet connected digital information at preset time. Alternatively, when the sensing unit  20  may receive the control signal of the remote control, the remote control unit  124  processes the control signal of the remote control. The signal processing module  12  is coupled with the storage module  24  to access the internet connected digital information. The storage module  24  may be a built-in flash memory, hard disk driver, storage memory, compact flash (CF), secure internet connected digital card (SD) or memory stick or the combinations thereof. Furthermore, the signal processing module  12  is coupled with the transmission connecting module  14  to receive or transmit the internet connected digital information. The transmission connecting module  14  may include various interfaces or connect ports to link to a network. The transmission connecting module  14  may be the transmission line interface of a computer photo. The transmission line interface may be a RS 232 interface, USB 2.0 interface, IEEE1394 interface, PCMCIA interface or the transmission line interface of a home network, such as a powerline interface, Home Phoneline Networking Alliance 3.0/3.1 interface, Homeplug interface and Multimedia over coax alliance interface or the combinations thereof, and so on.

Furthermore, the output unit  18  may be a display, such as a LCD display, OLED display or PDD display. 
         [0018]    Accordingly, the sensing unit  20  transmits the control signal which represents a user or viewer&#39;s presence to the signal processing module  12  or the ambient light intensity of the environment. The signal processing module  12  analyzes the control signal to determine the display of the internet connected digital information. On one hand, when the control signal represents no one is around the internet connected digital photo frame  10  or the ambient light is low, the signal processing module  12  sends a command for interrupting the display of the internet connected digital information to render the internet connected digital photo frame  10  stand in a standby state for power saving. On the other hand, the command for interrupting playing or displaying is also sent to the power module  22 . The power module  22  alters the display effects of the output unit  18 , such as reduces or turns off the brightness of the output unit  18 . On the other hand, when anyone is close to the internet connected digital photo frame  10  or the ambient light is increased the signal processing module  12  sends a display command to drive the internet connected digital photo frame from the standby state. The power module  22  may alter the display of the output unit  18 , such as recover or turn on the brightness of the output unit  18 . Accordingly, the internet connected digital photo frame of the present invention may provide various display effects and play effects in accordance with the existence of a user or viewer around the internet connected digital photo frame and/or the ambient intensity of the environment. 
         [0019]    Next, the internet connected digital information may be displayed or played at the preset time. For example, the internet connected digital information is a customized content, which may be established in the web sites of Portal Service or Aggregator. At the preset time, the signal processing module  12  may send a displaying command to display the customized content. An updated content may be transmitted via the transmission connecting module  14  according to the displaying command to the signal processing module  12 . Then the updated content together with the existed content in the storage unit is transmitted to the output controlling module  16  and then displayed by the output unit  18 . Accordingly, the internet connected digital photo frame of the present invention may provide the latest content according to the user&#39;s presetting and play the role of a flash bulletin. Thus, without use of a computer, a user may review any internet content with the internet connected digital photo frame. 
         [0020]    Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that other modifications and variation can be made without departing the spirit and scope of the invention as hereafter claimed.
