Summary of the invention
But the miniature digital VTR that the purpose of this utility model is to provide a kind of small acoustic control to trigger.
The utility model is that the technical scheme that is adopted that achieves the above object is: design a kind of miniature digital VTR, comprise optical lens, cmos sensor, processor, memory, microphone, power-supply controller of electric, control button, optical lens is arranged on the place ahead of cmos sensor, and cmos sensor, memory, microphone, control button and power-supply controller of electric are connected with processor respectively; Also be provided with the acoustic control trigger switch, the acoustic control trigger switch is connected with processor, and processor is connected with the acoustic control processing module, and the output of acoustic control processing module is connected with power-supply controller of electric.
The utility model is except that the conventional func with common camera, have characteristics such as volume is little, sounds trigger is made video recording, the storage of Micro SD card, USB computer charge function, full speed USB connection, can duplicate cut and paste to Micro SD card data by equipment such as PCs.The utility model both can be used for daily domestic safety monitoring, also can be used for meeting, teaching record, outdoor exercises record, audio-visual amusement, municipal administration's law enforcement or law enforcement for environmental protection evidence obtaining and monitoring, reporter's evidence obtaining or other recording purposes.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of miniature digital VTR, comprise optical lens, cmos sensor 1, processor 2, memory 3, microphone 4, power-supply controller of electric 5, control button 6, optical lens is arranged on the place ahead of cmos sensor 1, and cmos sensor 1, memory 3, microphone 4, control button 6 are connected with processor 2 respectively with power-supply controller of electric 5; Also be provided with acoustic control trigger switch 7, acoustic control trigger switch 7 is connected with processor 2, and processor 2 is connected with acoustic control processing module 8, and the output of acoustic control processing module 8 is connected with power-supply controller of electric 5.
When start pushed out mains switch, power-supply system was connected.No any operation in continuous 2 minutes after the start, system enters battery saving mode (STANDBY) pattern.Under power on mode, but entering the video recording pattern, button begins video recording, the indicator light green LED is bright, green LED quickflashing when the storage card record is full.Button when video recording stops video recording, and the image of recording is saved as a video files.
When mains switch pushed the pass, after system can preserve the data of not preserving and finish, system entered off-mode.
Acoustic control control switch 7 is pushed out, and under power on mode, when there was sound in the external world, system entered the video recording pattern, when noiseless situation then stopped video recording in continuous 2 minutes, and entered battery saving mode (STANDBY).Under battery saving mode (STANDBY), when there was sound in the external world, the meeting waken system also entered the video recording pattern, then stopped video recording in continuous 2 minutes when detecting noiseless situation, and entered the STANDBY pattern.Acoustic control control switch 7 pushes when closing, and will can not enter acoustic control automatic video recording pattern, can only manually record a video.
Also comprise USB interface 9, USB interface 9 is connected with processor 2.Described USB interface 9 is a Min 5Pin Type B interface.USB interface also is used for powering except that being used for transfer of data, realizes that power supply input and usb data transmission are integrated.By the USB interface charging, but the computer charging makes charging more convenient.
Mains switch pushes when closing, and inserts the USB plug that is connected with computer, enters charge mode.If only need the charging of this machine in order to save the charging interval, is please pushed the pass with mains switch.When mains switch is pushed out, the USB flash disk pattern can be entered, on PC, a portable hard drive symbol can be occurred.
Also comprise internal battery 10, battery 10 is connected with power-supply controller of electric 5.Described internal battery 10 is a lithium battery; Also be provided with charging circuit 11, the input of charging circuit 11 is connected with power-supply controller of electric 5, and the output of charging circuit 11 is connected with internal battery 10.11 of charging circuits provide charge power supply for internal battery 10.
Also comprise the outer plug-in card deck, the contact that is arranged in the outer plug-in card deck is connected with processor.
Described memory 3 is the SD card.The SD card is a Micro SD card.
For reaching the less purpose of build, described optical lens is a pin hole type optical lens.
The utility model volume is little, and is easy to carry; Function is hommization more, and is simple to operate, operating instruction that need not be loaded down with trivial details; Built-in pinhole lens makes subminaturization become possibility; Can clean camera lens, len; Band Micro SD card memory function supports built-in SD to stick into the storage of this machine of row; High pixel CMOS is provided, makes image effect more clear; By built-in MIC, can trigger by acoustic control and record and make video recording; Realize sound, the integrated storage of video; Support the USB1.1 interface, possess the high speed USB data transfer function, can be undertaken that data are duplicated, cut and paste by terminal equipments such as PCs; By the USB interface charging, but the computer charging makes charging more convenient; Built-in polymer Li-ion battery, but recharge; Realize the storage of high speed dynamic image; Integrated lamp control indication is provided, comprises work indication, charging indication, low electricity indication, video recording indication.
