Embodiment
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is a kind of structural representation with Digital Video of recognition of face encryption function provided by the invention.
Referring to Fig. 1, the invention provides a kind of Digital Video with recognition of face encryption function, include and take unit 101, photo storage unit 102, recognition of face judging unit 103 and image-display units 104, wherein:
Take unit 101, the image information that is used to take the Digital Video outside is specially the shooting of carrying out Digital Video the place ahead scenery, for example can take Digital Video owner's head photo;
Photo storage unit 102 is used for storing in advance Digital Video owner's self head photo and the captured image information of Digital Video, can also store other users certainly and want the file stored;
Recognition of face judging unit 103, respectively with shooting unit 101, photo storage unit 102, image-display units 104 is connected, be used for when the browsing file instruction that receives active user's input, trigger the image information that a number sign indicating number video camera outside is taken in described shooting unit 101, and the personage's head image in this image information of identification extraction, then with in this personage's head image and the described photo storage unit 102 in advance Digital Video owner's the head photo of storage carry out matching ratio, comparative result is that similarity is when reaching the predetermined value scope, the artificial Digital Video owner of current this Digital Video of use is described, read the captured image information of Digital Video of storage in the described photo storage unit 102 in real time, and be transmitted to image-display units 104 and show, allow the user to browse file in the Digital Video; If comparative result is that similarity is not in the predetermined value scope time (inequality fully), the captured image information of Digital Video to storage in the described photo storage unit 102 does not carry out read operation, does not promptly allow the active user to browse file in the Digital Video;
Need to prove that described predetermined value scope can be set in advance according to the needs of user and video camera manufacturer, for example can be 80% ~ 100%.
Image-display units 104 is connected with recognition of face judging unit 103, is used for playing in real time the image information that described recognition of face judging unit 103 is transmitted.
Therefore; for the present invention, can discern automatically and judge that whether current Digital Video user is the Digital Video owner, realizes automatic person recognition; improve the usage safety performance of Digital Video greatly, protected Digital Video owner's privacy and vital document safety.
For the present invention, need to prove that also on the specific implementation, described recognition of face judging unit 103 can be existing face recognition module.Face recognition module mainly is to judge identification people face according to the approximate shape of the relative position of eyes and mouth and face.At present, be that core has formed multiple face identification system with the face recognition module, had widely and used: recognition of face access management system, recognition of face access control and attendance system and recognition of face video monitoring system or the like.
In the present invention, described shooting unit 101 can for example can be the CCD(charge coupled device for comprising the image acquisition component of imageing sensor in the Digital Video) imageing sensor.
In the present invention, described photo storage unit 102 is preferably and adopts nonvolatile random access memory (Non-Volatile Random Access Memory, NVRAM), this memory is the semiconductor memory that data still can keep after outage, thereby guarantees that the photo that this photo storage unit is stored above can not lose because of outage.
At present, described NVRAM memory comprises SD card (Secure Digital Memory Card, safe digital card) and the flash memory extension storage card of other types, for example, SONY memory stick, multimedia card (MMC), the nand flash memory that CF card (Compact Flash) and Digital Video are built-in etc.These polytype NVRAM memories can make things convenient for the user to read and deposit in photo.
In the present invention, described recognition of face judging unit 103 can also be the central processor CPU on the Digital Video mainboard, digital signal processor DSP or single-chip microprocessor MCU.
In the present invention, described image-display units 104 can be the electronic liquid crystal display screen LCD that installs on the given figure sign indicating number video camera mainboard.
For the present invention, on the specific implementation, the user can come by the button that is provided with on the Digital Video surface to recognition of face judging unit 103 input file browsing instructions, thereby start 103 work of recognition of face judging unit, read the personage's head image in the described shooting of the identification unit 101 captured image informations in real time, head photo with Digital Video owner in this head image and the described photo storage unit 102 carries out matching ratio then, at comparative result when being identical, just allow the active user to browse file in the Digital Video.
For the present invention, in order to start the recognition of face encryption function, referring to Fig. 2, its concrete operations flow process can for:
Step 1: under the Digital Video open state, press menu MENU button, select to be provided with option;
Step 2: in option is set, select the recognition of face encryption function;
Step 3: select whether to start the recognition of face encryption function;
Step 4: autodyne by the key of taking pictures when browsing pictures and file;
Step 5: can browse after contrasting successfully.
For the present invention, referring to Fig. 3, in order to realize the recognition of face encryption function, concrete treatment step is as follows:
The first step: the user at first takes self a photo and is kept in the video camera, and this photo is used for needing to open when encrypting the contrast photo later on;
Second step: when after the user is starting encryption function, needing to browse photo and checking in the video camera storage file, need take self a photo again;
The 3rd step: the program of the face identification functions in the video camera compares these two photos then, and similarity reaches regulation numerical value, and the user just can browse the file of photo and storage, otherwise, do not allow to browse all files of storing in the Digital Video.
In sum, compared with prior art, a kind of Digital Video provided by the invention with recognition of face encryption function, its effectively the logarithmic code video camera encrypt, prevent that people outside the Digital Video owner from browsing the file in the Digital Video, increase the fail safe of Digital Video storage greatly, help improving the use experience of user's logarithmic code video camera product, be of great practical significance.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
