Specific embodiment
Be referred to accompanying drawing Fig. 1～Fig. 3 below and word content understand present disclosure and the present invention with existing
Distinctive points between technology.Hereafter by accompanying drawing and enumerate the present invention some alternative embodiments by way of, to the present invention's
Technical scheme (inclusion optimal technical scheme) is described in further detail.It should be noted that：Any skill in the present embodiment
Art feature, any technical scheme are all one or more of the technical characteristic of plurality of optional or optional technical scheme, in order to
Description is succinct, and need in presents cannot all alternative technical characteristic of the exhaustive present invention and alternative technical side
Case, the embodiment being also not easy to each technical characteristic all emphasizes that it is one of optional numerous embodiments, so this area
Technical staff should know：Any two arbitrary technological means that the present invention provides being replaced or the present invention being provided
Individual or more technological means or technical characteristic are combined mutually and obtain new technical scheme.Any skill in the present embodiment
Art feature and any technical scheme all do not limit the scope of the invention, and protection scope of the present invention should include this area
Technical staff does not pay the creative work thinkable any alternate embodiments of institute and those skilled in the art by the present invention
Any two providing or more technological means or technical characteristic be combined mutually obtained from new technical scheme.
A kind of method embodiments providing filming apparatus and shooting, can by improving to this filming apparatus
To increase the convenience of this filming apparatus use.
Illustrated in more detail with reference to the technical scheme that Fig. 1～Fig. 3 provides to the present invention.
As shown in figure 1, a kind of filming apparatus that the embodiment of the present invention is provided, including：Sonic generator 21, for logarithm
According to carrying out processing microprocessor 1 and for shooting the shooting unit 3 of main body.
Described shooting unit 3 includes：Motor 31, lens 32 and optical pickocff 33.
Described microprocessor 1 includes：Signal processing of sonar unit 11, for processing to Sonar Signal；Distance positioning
Unit 12, for carrying out Distance positioning by Sonar Signal to shooting main body；Focusing fitting unit 13, for by Distance positioning list
The Distance positioning data of unit 12 output is fitted with the focus data of shooting unit 3.
Existing filming apparatus will realize auto-focusing, all can have a travel schedule, in travel schedule from Inf end to Macro
Several sampled points are set, substantially than comparatively dense, Macro end is than sparse at Inf end in the whole stroke at end.Automatically right
When burnt, travel schedule in microcomputer reads algorithm, assign instruction and arrive motor driving chip, by changing the electric current exporting
Size, to adjust the position of Lens, then obtains pictures, then using the clear degrees of data calculating this pictures.Whole
After travel schedule is run through, if there being the clear degrees of data of at least one pictures to reach default threshold value in all sampled points, then
Just using corresponding for definition highest picture sampled point as focus target point, drive shooting unit to relevant position, focus into
Work(；If the clear degrees of data of all sampled points all can not reach threshold value, focus unsuccessfully, shooting unit to Inf or No
Power point.So the auto-focusing of existing filming apparatus typically will run through whole travel schedule.The filming apparatus invented pass through sound
Wave producer 21 just can determine focus target point after determining distance, direct drive motor adjustment shooting unit 3 reaches accordingly
Position is realizing quickly focusing.
Compare other technologies, and Sonar Signal is not affected by light, can truly reflect the dimensional orientation of all objects,
Main body to be shot can accurately be oriented, shot, thus the present invention by Sonar Signal the light pair to shooting unit 3
Burnt data is assisted, thus more accurately and be rapidly performed by focusing.Additionally, compared to existing technology, when shooting, by borrowing
Sonar Signal is helped to be quickly obtained rough focal distance, at this moment drive motor 31 drives lens 32 to navigate to relevant position, so
Combine optical pickocff 33 afterwards in corresponding fine position lens, thus can reach the purpose quick and precisely focused.Due to
Motor, without running through focusing stroke, is directly targeted to corresponding focal distance, is then finely adjusted again, thus accelerating focusing speed
Degree.
As shown in Fig. 2 present invention also offers a kind of fish deteclor, this fish deteclor includes popping one's head in 2, also includes above-mentioned shooting dress
Put, wherein sonic generator 21 is arranged on probe 2.Compare existing fish deteclor, and Sonar Signal is not affected by light, energy
Truly reflect the dimensional orientation of all objects, main body to be shot can accurately be oriented, shot, so the present invention borrows
Help Sonar Signal that the light focus data of shooting unit 3 is assisted, thus more accurately and be rapidly performed by focusing.This
Outward, compared to existing technology, when shooting, by being quickly obtained rough focal distance by Sonar Signal, at this moment drive horse
Reach 31 driving lens 32 and navigate to relevant position, then in conjunction with optical pickocff 33 in corresponding fine position lens, thus
The purpose quick and precisely focused can be reached.Because motor is without running through focusing stroke, it is directly targeted to corresponding focal distance,
Then it is finely adjusted, thus accelerating focusing speed again.
As shown in figure 3, present invention also offers a kind of image pickup method, using above-mentioned filming apparatus, methods described includes：
S1. pass through sonic generator transmitting Sonar Signal of popping one's head in；
S2. probe receives sonar echo；
S3. Signal processing of sonar unit is processed to Sonar Signal, and is entered to shooting main body by Distance positioning unit
Row distance positions；
Distance positioning data and the focusing number of shooting unit that Distance positioning unit export by the fitting unit that S4. passes through to focus
According to being fitted.
Compare other technologies, and Sonar Signal is not affected by light, can truly reflect the dimensional orientation of all objects,
Perception is photographed object distance, can accurately orient main body to be shot, be shot, so can divide object and background
From so the present invention assists to the light focus data of shooting unit 3 by Sonar Signal, thus carrying out perhaps different photographs
Piece effect. thus more accurately being focused, reducing and shooting unsharp probability.
