Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below:
The basic principle of digital camera, be to utilize the scenery of optical sensing subassembly (for example CCD or CMOS) under shooting a scene, after passing through complicated operation program such as conversion of signals, digitlization and compression (compress) again, be compressed video data with the picture conversion under the camera lens and deposit in the storage card.In other words, digital photo is that the kenel with compressed video data is stored in the storage card, compression ratio during according to data processing (compress rate) difference, it is poor more that digital photo also has the high more then resolution of different resolution (resolution)-compression ratio.When browsing digital photo, the compressed video data in the storage card need be decompressed, the work of decompression can utilize Video Decoder (decoder) to be realized, for example jpeg decoder etc.When compressed video data is decompressed be digital video signal after, LCD can be presented digital photo as long as show according to the digital video signal that solved.Emphasis of the present invention promptly is to utilize LCD to play-over digital photo, to promote the convenience of browsing photo.
Please refer to Fig. 1, it illustrates the LCD calcspar according to a kind of tool digital frame function of one embodiment of the present invention.Video Decoder 130, control assembly 140, proportioning device (scaler) 150 and liquid crystal panel (LCD panel) 170 all are disposed on the LCD, and the shell place of LCD also is provided with storage card slot (not illustrating), storage card slot and Video Decoder 130 couple, in order to storage card 110 and Video Decoder 130 are electrically connected.After the user plugs storage card slot with storage card 110, can be with the compressed video data CVD feed-in Video Decoder of being stored in the storage card 110 130, with the work that decompresses; Wherein Video Decoder 130 for example is the specification that meets Joint Photographic Experts Group.
After Video Decoder 130 receives compressed video data CVD, its decompress(ion) can be condensed to digital video signal DVS, utilize transmission circuit 135 that digital video signal DVS is exported again.Transmission circuit 135 can utilize coffret TRIF that digital video signal DVS is sent to proportioning device 150, is received by the digital video processor in the proportioning device 150 (Digital Video Input) 155, and carries out follow-up Video processing work.Wherein coffret TRIF for example is the interface specification that meets CCIR601 or CCIR656 standard, and digital video signal DVS for example is the specification that meets the YUV422 video format.It should be noted that between Video Decoder 130 and the proportioning device 150 and can pass through control signal CTRL mutual communication, to finish the transmission work of digital video signal DVS; Wherein control signal for example is the specification that meets standards such as I2C or RS-232.In practical application, control signal CTRL can utilize control assembly 140 to produce, even has developed the proportioning device 150 that can produce control signal CTRL voluntarily now, can link up with Video Decoder 130 without leave, need not be subjected to outside control.
After digital video processor 155 receives digital video signal DVS, proportioning device 150 can produce liquid crystal panel (LCD panel) 170 needed shows signal DS according to the parameters among the digital video signal DVS (for example brightness or resolution etc.), makes liquid crystal panel 170 show digital photo in the storage card 110 according to shows signal DS.
Importantly, owing to be converted to the process fully digitalization of shows signal DS, therefore do not have distorted signals, decay or be subjected to situation such as noise jamming to take place, can keep the high validity of digital photo from compressed video data CVD.Moreover, proportioning device 150 is an assembly existing in the LCD, the present invention only need add Video Decoder I30, compressed video data CVD in the storage card 110 can be converted to the supported digital video signal DVS of LCD, utilize liquid crystal panel 170 to be shown, realization is exempted to start shooting and can be browsed the purpose of digital element photograph, and convenience more greatly promoted.
The LCD of the disclosed tool digital frame of the above embodiment of the present invention function has the following advantages at least:
One, can directly browse digital photo, not need the cooperation of other main frame with LCD screen.
Two, the proportioning device that utilizes LCD screen itself to have is made digital video signal processing, and is with low cost.
Three, signal processing fully digitalization can effectively avoid distorted signals, decay or be subjected to situations such as noise jamming to take place, to keep the validity of digital photo.
In sum; though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; any those skilled in the art; do not breaking away from the spirit and scope of the invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the claims scope person of defining.
