Compared with prior art, adopt digital camera of the present invention to start, stop the program of making video recording that circulates by first and second time shutter action, and in program is made video recording in circulation, the storage mode of image data with first-in first-out is stored in the temporarily providing room of a predetermined volumes, the storage mode that utilize legacy data to overflow, new data deposits in realizes that the best picture of camera shooting is accurately caught.Method proposed by the invention is only programmed by limited hardware and appropriate software and is realized simultaneously, helps the control of camera cost.
[description of drawings]
Fig. 1 is the system flowchart according to digital camera of the present invention.
Fig. 2 is according to clip recording method for digital camera process flow diagram of the present invention.
[embodiment]
A kind of clip recording method for digital camera, the storage mode that utilize legacy data to overflow, new data deposits in, the circulation storage of programming and realizing image data by limited hardware material and appropriate software.The method includes the steps of:
1), starts the circulation program of making video recording by pressing mode such as shutter;
2) pick-up image data are stored in image data in the temporarily providing room of camera one predetermined volumes and are ended until the circulation program of making video recording with the storage mode of first-in first-out; And
3) camera is with image data storage in the temporarily providing room.
Below in conjunction with graphic the specific embodiment of the present invention is described.Figure 1 shows that system flowchart according to a clip recording method for digital camera of preferred embodiment of the present invention.At first, camera is opened, and system begins initialization (step S01).After system initialization is finished, camera detection hardware state, errorless as hardware state, camera enters working routine (step S02 to S03), otherwise camera returns, and prompting operation person's hardware state make mistakes (step S021).In service in working routine, camera whether end of input instruction of detecting operation person at any time, as run into END instruction, then deactivate program and shutdown (step S04 to S05) of camera, camera operation finishes.
When camera entered working routine, the operator can be set to the pattern of making video recording that circulates by camera as required.Make video recording modal index position camera of described circulation uses the mode of operation of clip recording method.Under this pattern, digital camera can be taken some precious camera lenses or special frame, and is unlikely to miss best right moment for camera, also can not make video recording always and cause too much taking of storage space because of waiting for picture to occur, even exhaust.When system carried out the pattern of making video recording that circulates, camera was in the state of making video recording always.
Please with further reference to Fig. 2, this figure has disclosed the workflow of digital camera under pattern is made video recording in circulation.Under pattern was made video recording in circulation, the operator treated to press shutter after parameter settings such as focal length and aperture are finished, and started the program of making video recording that circulates.When program start was made video recording in circulation, camera was obtained initial image time point, and began pick-up image (step 201 is to 203) from initial image time point.
The continuous pick-up image of camera, and institute's picked image is temporary in (step 204 is to 205) in the camera temporarily providing room according to the storage mode of storehouse first in first out.The capacity of described temporarily providing room is determined constant, and its amount of capacity determines the length of storable image data.When institute's canned data exceeded the predetermined volumes of cushion space, camera was obtained present image time point automatically and next image time point is made as the initial time point, and whether camera detecting operation person presses shutter (step 206 is to 208) for the second time simultaneously.Detection signal feedback as camera shows that shutter is not pressed once more, and system returns step 203, restarts the pick-up image data according to the initial image time point of obtaining just now.And when the detection signal feedback of camera showed that shutter has been pressed for the second time, camera was gone into image data unloading in the temporarily providing room (step 209) in the camera memory automatically, and the operator can choose only picture from the image data that is stored into storage card.
But the clip recording method for digital camera that preferred embodiment of the present invention disclosed can capture the best opportunity of camera filmed image exactly.In camera circulates the process of making video recording, when camera surpasses the amount of capacity of camera temporarily providing room when the data volume of image capture, new picked image numerical information is according to the storage mode of first in first out, constantly new data are write temporarily providing room, make old data overflow described temporarily providing room and lose simultaneously.The mode that this circulation is made video recording not only can be utilized storage space expeditiously, can also guarantee that important picture can not missed.Interrupt circulation time when the operator presses shutter for the second time, camera is stored into the present image data of depositing in the buffer rcgister in the camera memory automatically.
In addition, clip recording method for digital camera also can be undertaken by alternate manner, as in temporarily providing room with different time points memory allocated unit, and time cycle of pick-up image is set.When program start was made video recording in circulation, camera was obtained initial image time point, began pick-up image from initial image time point, and the time point of institute's picked image according to this image capture is stored in the corresponding storage unit.When the pick-up image time surpassed the time span of predetermined period, camera made zero the image time automatically, and next image time point is made as the initial time point, and whether camera detecting operation person presses shutter for the second time simultaneously.Detection signal feedback as camera shows that shutter is not pressed once more, system continues the pick-up image data according to the initial image time point of obtaining just now, and new image data is stored in the periodically corresponding storage unit according to the time point of this image capture, and the image data of last cycle corresponding image time point is covered.When the detection signal feedback of camera showed that shutter has been pressed for the second time, camera was gone into image data unloading in the temporarily providing room in the camera memory automatically, and the operator can choose only picture from the image data that is stored into storage card.
The best opportunity that this clip recording method only realizes capturing exactly the camera shooting picture by limited hardware and appropriate software program, help the control of camera cost.
