Can more be expressly understood of the present invention above-mentioned purpose and advantage thereof with reference to accompanying drawing to the detailed description of most preferred embodiment by following.
Brief Description Of Drawings:
Fig. 1 is a block diagram, and expression is according to the structure of a kind of digital video camera of the present invention;
Fig. 2 is a flow chart, and expression is according to a kind of recording method of using the data of snapshot camera style shooting of the present invention; And
Fig. 3 is a flow chart, and expression is according to a kind of method of the present invention, is used at a high speed retrieval and takes and be recorded in view data on the recording medium with the snapshot mode, and transmit this view data.
Device shown in Fig. 1 comprises an input unit 10 that is used to provide predetermined instruction; A recorder/reproducer apparatus 12; A detection signal detector 14 is used for detecting with snapshot mode shot image data; The view data that conveyer 16 is used for capturing sends personal computer (PC) 20 to; And controller 18.
Input unit 10 provides the instruction of taking and retrieving automatically and transmit quick-taking photographic image data with the snapshot mode.
Recorder/reproducer apparatus 12 comprises gamma camera 120; Signal processor 122; Modulation and demodulation device 124; Amplifier 126; Recording medium 128; And a sub-code data is handled processor 130.In recording mode, a corresponding respectively video area and the subcode area on recording medium of recorder/reproducer apparatus 12 writes down with snapshot mode shot image data and the detection signal that is used to detect quick-taking photographic image data.Under retrieval mode, recorder/reproducer apparatus 12 comes the view data of search records by detection signal, and captures the data that retrieve.
The snapshot photography detection signal of detection signal detector 14 detection of stored in the subcode area of recording medium 128.
Conveyer 16 comprises a parallel-to-serial data converter 160; A memory 162, and a level translator 164.Conveyer 16 is stored in the view data of capturing in the recorder/reproducer apparatus 12, and is that unit transmits this view data according to predetermined control signal with a frame.
Controller 18 receives predetermined instruction from input unit 10, the operation of control detection signal detector 14, receive snapshot photography detection signal from detection signal detector 14, controlling recording/reproducing unit 12, so that the corresponding view data of the detection signal of capturing and receiving, and control conveyer 16 is to transmit the view data that captures to PC20.
The working method of following key diagram 1 shown device.
At first, when a snapshot photography instruction is provided by input unit 10, controller 18 is with regard to control signal processor 122, respectively the view data that record gamma camera 120 photographs in the video area of recording medium 128 and subcode area and the detection signal of corresponding this view data.On the other hand, the data of the subcode area of handling in 130 pairs of signal processors 122 of sub-code data processor are that detection signal is encoded.
Providing one to be used for from the recording medium 128 retrieval quick-taking photographic image datas instruction of writing down the snapshot photographed data and to provide when transmitting the instruction of the view data that retrieves by input unit 10, controller 18 control detection signal detectors 14 restart once to receive from detection signal detector 14 operation of detection signal, control this signal processor 122 capturing, and control conveyer 16 is transmitted in the view data of capturing in the signal processor 122 to view data that should recall signal.
Conveyer 16 converts the parallel data of signal processor 122 output to serial data, is unit storage data converted with a frame, and the serial data level conversion is become to meet the level of RS-232C agreement and the data after PC20 transmits conversion.
In the present invention, according to detection signal come retrieve stored in recording medium a plurality of quick-taking photographic image datas and the view data that retrieves to be sent to sequence of operations such as PC be to carry out continuously and automatically.
Fig. 2 is a flow chart, and expression is according to a kind of recording method of using the data of snapshot camera style shooting of the present invention.
Provide a snapshot photography instruction in the step 200.
In the step 202, with the frame image data taken and the detection signal that is used for detecting this view data be recorded in respectively on the video area and subcode area of recording medium.
Fig. 3 is the flow chart that is used for representing according to a kind of method of the present invention, is used for retrieval at a high speed and takes and be recorded in view data on the recording medium with the snapshot mode, and transmit the view data of this retrieval.
The instruction that in the step 300, automatic retrieval quick-taking photographic image data is provided and transmits these data.
In the step 302, determined whether to detect the detection signal of the quick-taking photographic image data in the subcode area.
In the step 304,, just capture the view data in should the video area of detected detection signal if detected detection signal.
In the step 306, transmit the view data that captures.Be that unit comes the transmitted image data with a frame at this moment.Then, finish (step 308), and the transmission of a frame image data finishes, just repeat the step 302 to the step 306, so that detect and transmit the view data of next frame if determined the transmission of frame unit's view data.
According to the present invention, the snapshot photography detection signal corresponding to the style of shooting of snapshot image data can be recorded on the subcode area, and between replicative phase, utilize this detection signal to carry out retrieval at a high speed and continuous transmission.
