Embodiment

For more understanding technology contents of the present invention, be described as follows especially exemplified by a preferred embodiment.

Fig. 1 shows the calcspar of digital photo-frame device 10 of the present invention, it comprises: compression/de-compression engine 11, buffer cell 12, video signal preprocessor (Video processor) 13, OSD (OnScreen Display) clock display unit 14, and boundary element 15, this digital photo-frame device 10 is to be arranged on the digital television, so that the digital television decapacitation is play outside the TV programme, functions such as photo memorandum and TV clock more can be provided, wherein, when playing TV programme, digitized TV signal number (YUV/RGB) frequently is temporary in earlier in the buffer cell 12, after 13 TV signal that these are staggered of video signal preprocessor are done deinterleave (de-interlace) processing, carry out suitable adjustment convergent-divergent (Scaling), upset (Rotation), shift position (Position) and being presented on the display floater 20.

Aforementioned buffer cell 12 is preferably a dynamic randon access holder (DRAM), it is in order to the temporary TV signal that will play or handle, aforementioned compression/de-compression engine 11 is preferably a JPEG engine, be in order to TV signal boil down to one JPEG archives with a picture, or a JPEG archives decompress(ion) is condensed to TV signal, this compression/de-compression engine 11 is to be coupled to this buffer cell 12, with when Digital Television when playing TV programme, when wanting to store the picture of present broadcast as selection, this compression/de-compression engine 11 will be compressed into the JPEG archives to the digital television signal of being kept in this buffer cell 12, and it is temporary these JPEG archives to be deposited back buffer cell 12 again.

Aforementioned boundary element 15 is to be coupled to this buffer cell 12, data in the buffer cell 12 can be writen to an external storage device 30, or read in data to this buffer cell 12 by external storage device 30, this boundary element 15 can be the USB interface or all kinds store card (SMC, MMC/SD, MS, CF) interface, accordingly, external storage device 30 can be a PC or with USB interface and stores card (SMC, MMC/SD, MS, CF), and the JPEG archives that are temporary in this buffer cell 12 after aforementioned, compressed/decompression engine 11 compressions just can be stored in the storage card through boundary element 15 or pass to the preservation that PC is done important image and data by USB.On the other hand, being stored in the JPEG archives or the dynamic image compression shelves (for example AVI shelves) that store in the card also can read to this buffer cell 12, do by this compression/de-compression engine 11 again and put into this buffer cell 12 after image decompresses, to carry out suitable adjustment convergent-divergent, upset, shift position etc. and to be shown in this display floater 20 via this video signal preprocessor 13.

Aforementioned OSD clock display unit 14 is to comprise a real-time clock 141 (Real Time Clock, RTC), a microprocessor 142 and a non-volatile storage 143, wherein, real-time clock 141 records the present time, then prestore the OSD time pattern of numeral or pointer shape in the non-volatile storage 143, Fig. 2 (A) shows a kind of digital OSD time pattern, it includes the pattern of numeral 0～9 and list separator, Fig. 2 (B) then shows a kind of OSD time pattern of pointer shape, and it includes the pattern of hour hands, minute hand and second hand.

Aforesaid external storage device 30 can prestore the JPEG archives of clock background patterns miscellaneous, be depicted as the clock background patterns of an aquarium style as Fig. 3 (A), then the clock background patterns of a traditional type wall clock shown in Fig. 3 (B), the JPEG archives of this isochronon background patterns can read in this buffer cell 12 via aforementioned boundary element 15, be temporary in this buffer cell 12 through de-compressing into of this compression/de-compression engine 11, adjust convergent-divergent via this video signal preprocessor 13 again to TV signal, upset, shift position etc. and the clock background patterns is shown on this display floater 20.

The present time that the microprocessor 142 of aforementioned OSD clock display unit 14 is write down according to real-time clock 141, the OSD time pattern that cooperation is read by non-volatile storage 143, and determine the position of present clock patterns to display and its demonstration, shown in Fig. 4 (A) and 4 (B), be respectively digital clock patterns and the pointer clock pattern of 9: 30: 21 present time, the mode that shows with OSD via the vision signal display is overlapped in this present clock patterns on this clock background patterns and shows again, shown in Fig. 5 (A) and 5 (B), and reach the time clock feature that numeral changes or pointer rotates.

By above explanation as can be known, the present invention is the application function that can increase digital photo-frame (DPF) in CRT, LCD, PDP and the Digital Television of different displays such as back projection newly, so that home-use TV set has multimedia video functions such as showing photo, the static vision signal photo of intercepting and data, photo album, clock demonstration, and reach make full use of Digital Television the image display capabilities to satisfy user's demand.

The foregoing description only is to give an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
