Embodiment
As shown in Figure 1, the utility model comprises switching circuit 1, controller (2,3,4), imageing sensor 11, digital signal processor 12, first in first out storage controller 13, memory 14, display circuit 17, the input of the output termination digital signal processor 12 of imageing sensor 11, the signal terminal of digital signal processor 12 connects display module 17, memory 14, between the information input terminal of the output of switching circuit 1 and digital signal processor 12, be connected with one or more controller (2,3,4).
As shown in Figure 2, switching circuit 1 is selected sound controling switch circuit for use, sound controling switch circuit is by microphone 31, amplifier 32 (model is LM358), threshold circuit 33 connects and composes, first controller 2 is selected for use to make video recording and is stopped delay controller (20,21) constitute, second controller 3 is selected replay delay controller (18 for use, 19) constitute, the 3rd controller 4 selects for use video recording beginning controller 16 to constitute, make video recording and stop delay controller (20,21) by the delayer 20 of making video recording, the stop control 21 of making video recording connects and composes, the output of the input termination threshold circuit 33 of the delayer 20 of making video recording, the output termination digital signal processor 12 of the stop control 21 of making video recording.
Replay delay controller (18,19) is connected and composed by replay delayer 18, replay controller 19, the input termination of replay delayer 18 delayer 20 of making video recording, the output termination digital signal processor 12 of replay controller 19.The output termination digital signal processor 12 of video recording beginning controller 16, its input termination switch 15.First in first out storage controller 13 is connected between digital signal processor 12 and the memory 14.Make video recording delayer 20, replay delayer 18 can discretely be provided with, and also can formation be set a shared wiring board.
Described cmos image sensor 11 can select for use TC5740, digital signal processor 12 can select for use TMS320C6204, memory 14 can select for use K9F5616U0B, display circuit 17 can select LM19SGFNZ07 for use; Delayer (20,18) can be selected LM555 for use, and the stop control 21 of making video recording can be selected ARM7 for use, and replay controller 19 can be selected ARM7 for use, and video recording beginning controller 16 can be selected ARM7 for use, and first in first out storage controller 13 can be selected ARM7 for use.
During use, for example in golf, finish the general 2-3 of continuing second by preparing batting.In this example, memory 14 can be set to 3 seconds time of record.The club square stance can produce the huge sound, utilizes this sound, the right moment for camera of may command the best.That is: before the batting, video camera is in shooting state always, and video camera writes down continuous moving image on the memory in the mode of first in first out, at this moment, is always keeping nearest 3 seconds moving image in the memory 14.Hit a ball a moment, audio-switch 1 detects the batting signal and delivers to digital signal processor 12, digital signal processor 12 postpones 1 second rear to be stopped to take, and amounts to 3 seconds motion image signal before will stopping to take and reappear on display circuit 17 with the speed (as slow motion) of appointment.That is to say that the sportsman can heavily see by display circuit 17 immediately and hit a ball preceding 2 seconds and the back 1 second entire exercise of hitting a ball, and makes the sportsman can be well understood to the motion process of self, thereby corrects the wrong part that operates quickly.Hit a ball preceding and hit a ball after the shooting time interval can set by digital signal processor 12.
