When the user imports message information, analog to digital converter 43 is converted to digital audio and video signals with the simulated audio signal that the user imports by microphone 42, and under the control of CPU11, digital audio and video signals is input to audio coder 44, be sent in the internal memory 2 after 44 pairs of digital audio signal codings of audio coder are handled and preserve.
When playing message information, to the leave a message memory address of information of CPU11 sends to audio decoder 17, audio decoder 17 obtains digital audio and video signals from internal memory 2, carry out being sent to digital to analog converter 18 after the decoding processing, digital to analog converter 18 is under the control of CPU11, digital audio and video signals is converted to simulated audio signal, plays back by loud speaker 6.
Fig. 5 shows the structure of the DPF that possesses message-leaving function that fourth embodiment of the invention provides, and for convenience of explanation, only shows part related to the present invention.
Present embodiment has increased camera 51 on the basis of existing DPF, increased sensing controler 52 and video encoder 53 in the control chip 1, to realize the message information of image, video mode.
When the user wanted the message of input video form, sensing controler 52 received the vision signal that camera 51 is gathered in real time.53 pairs of vision signals of video encoder carry out being sent to preservation in the internal memory 2 behind the video coding.
During the message information of displaying video mode, Video Decoder 16 reads the message information in the internal memory 2, carries out video decode and handles, and display driver 13 generates the control signal of display screens, and the message information of video mode is presented on the display screen 4.
As the fifth embodiment of the present invention, the 3rd embodiment and the 4th embodiment combination can be realized the message information of sound, video mode simultaneously.As shown in Figure 6, when sensing controler 52 receives the vision signal of camera 51 collections in real time, microphone 42 obtains audio signal in real time, the vision signals that CPU11 receives synchronously to sensing controler 52 and analog to digital converter 43 are with after audio signal is stamped identical timestamp respectively, sensing controler 52 is sent to video encoder 53 in real time with video information, analog to digital converter 43 is sent to audio coder 44 in real time with audio-frequency information, with vision signal and audio signal together with timestamp by behind the coding respectively, be sent in the internal memory 2 and preserve.When message information shows, can pass through display driver 13 respectively, and digital to analog converter 18 with video information and audio-frequency information synchronous playing in display screen 4 and loud speaker 6.
Obviously, in the present invention, can be in DPF integrated two kinds or two or more message patterns simultaneously, to satisfy user's different demands, switching command by the mode switch control unit (not shown) basis that is connected with CPU11 receives switches between different message patterns.
In the above-described embodiments, the user can also be provided with by pattern or the effect that the 19 pairs of messages in message information configuration unit show except can editing the message content.
For example, can select different message display modes: the one, regularly or every the time show, promptly show message information at predefined time point or every the time period of setting; The 2nd, decide figure and show, promptly when showing, medium such as previously selected picture, video, animation show message information; The 3rd, the combination of above-mentioned two kinds of patterns, promptly regularly or every the time set background that message information shows when showing for medium such as the picture set, animations, also can be that background is certain selected color in 65536 looks; The 4th, show all the time, promptly set message information and be in show state all the time; The 5th, prompting shows, promptly only shows the prompting sign of message information, informs that the user has message information, opens the message information data by the user, in this pattern, can also encrypt the message information data, opening of message information data promptly is set needs the input password.
The display effect of message information also can be set, the font of the information of for example leaving a message, the color of font and size, whether roll display, whether glimmer shows etc., wherein, described flicker shows when being meant the demonstration of message information, constantly change by the brightness that display background is set, thereby produce the effect of flicker.
In addition, the user can also select multiple color or the default background picture background as message information, and can dispose message information and show separately, perhaps covers on the digital photo that DPF showing, and is deleted up to message information.
In the present invention, the user also can be earlier be provided with the display mode of message information, display effect etc., import concrete message content again, for example, the display mode that message is set earlier as the user shows for fixed figure, and selected medium, when then the user imports the message content, promptly playing the medium that the user selectes on the display screen.In addition, user's message information and as the medium that message is play background can store with by in memory card interface 3 and the storage card that DPF is connected, read to storage card or from storage card by will leave a message information or media store of CPU11 control store card controller 12 realizations.
The present invention makes DPF possess message-leaving function by integrated corresponding message message input device in DPF, has expanded the purposes of DPF, has satisfied user's demand, has improved the product integrated level of DPF.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
