Embodiment
See also Fig. 1, Fig. 1 illustrates the functional block diagram according to camera 1 in the wherein specific embodiment of the present invention, and in this embodiment, camera 1 comprises contact panel 10, filming image module 12 and microprocessor 14.Microprocessor 14 couples with contact panel 10 and filming image module 12 respectively.
In this embodiment, filming image module 12 comprises zoom unit 120 and aperture unit 122.Wherein, filming image module 12 can be in order to the acquisition shooting picture, and camera 1 can be set the photography focal length of shooting picture by this zoom unit 120, and on the other hand, camera 1 can be set the photographic aperture of shooting picture by this aperture unit 122.
In general, many objects may be contained in the shooting picture, various image elements such as theme and background may be comprised.The user is in when video recording, wishes that mostly the theme part can clear and definite, and builds suitable Deep Canvas.See also Fig. 2, Fig. 2 is illustrated in the synoptic diagram of the shooting picture P1 that filming image module 12 is captured in the operational instances.In the shooting picture P1 of Fig. 2, have the far and near various objects that are not quite similar of distance, for example the butterfly 101 of close together, at horizontal trees 103,105, house 107 and day aerial moon 109 etc., the camera 1 among the present invention can be chosen above-mentioned object as focus target.
In this operational instances, the user to be ready recording the film of relevant butterfly ecology, the user operates camera 1 and chooses butterfly 101 as focus target, adopts suitable focal length to set at butterfly 101, in the hope of the dynamic image of butterfly 101 clearly being noted.
At this moment, the general known automatic focusing account form that camera adopted, its way is by the possible theme object of searching in the whole image, and calculates formation " autofocus frame " automatically and aim at possible theme object, and the focal length of generation the best is according to this set.General known automatic focusing determining program, usually the object to picture central authorities gives higher theme probability weight (probability weight), in shooting picture P1, the house 107 rough picture middle sections that are positioned at because of background, make camera 1 just may focus automatically, and cause the focus target (being butterfly 101) that desire is taken in the user mind to lose burnt the house 107 in a distant place.
In this embodiment, camera 1 of the present invention can be carried out a kind of photographing setting control method, to make things convenient for the user can specify the focus target that desire is taken in the mind voluntarily, present effect to reach preferable photography, and particularly, focus target can be arranged in each corner of picture, is not limited to the middle position of picture.See also Fig. 3 and Fig. 4 A, Fig. 3 illustrates the method flow diagram according to photographing setting control method in the wherein specific embodiment of the present invention, and Fig. 4 A is illustrated in the operational instances and forms the synoptic diagram of making focusing frame f1 by oneself when the user touches contact panel 10 in shooting picture P1.
At first, when this touch panel detection arrives user's touching, in photographing setting control method of the present invention,, form the opposite position of in the shooting picture P1 of camera 1, touching from the frame f1 (shown in Fig. 4 A) that sets the goal with the user just can utilize microprocessor 14 execution in step S 100.
Then, just can be by microprocessor 14 execution in step S102, by acquisition first focus target among the frame f1 that sets the goal certainly, for example in this embodiment, microprocessor 14 just can be by judging with the butterfly in the picture 101, as first focus target herein among the frame f1 that sets the goal certainly.
Above-mentioned by the mechanism of judging and capture focus target in the specific region, can be realized that this people by known techniques is known, and does not give unnecessary details in addition at this based on imaged object identification algorithm, target edges detecting algorithm or other coherent video Processing Algorithm.
Then, just can calculate first focal length value according to this this first focus target (being butterfly 101) in the frame f1 that sets the goal, and see through the photography focal length that camera 1 is adjusted in this zoom unit 120 according to this first focal length value by microprocessor 14 execution in step S104.At this moment, camera 1 just can be adjusted to suitable focal length by corresponding first focus target (butterfly 101), to obtain photographic effects clearly.Certainly, the selected focus target of above-mentioned picture is not limited in butterfly 101, in the practical application, also can be the target that trees 103,105, the moon 109 or any user's desire are taken, and filming image module 12 is adjusted to suitable focal length according to the focus target of choosing.
In the above-described embodiments, camera 1 and photographing setting control method have high-freedom degree and allow the focusing option of user's touch-control appointment, and aforesaid operations flow process (step S100 is to step S104) can be described as the focusing flow process that the user makes by oneself.Yet in actual applications, camera 1 also is preset with autofocus mode simultaneously usually except the focusing flow process that can carry out the user and make by oneself, in wherein one implementing in the profit, when the user touch-control specify when not making the focusing frame by oneself, camera 1 can be carried out automatic focusing to take.
In this embodiment, after step S104 finished, microprocessor 14 is execution in step S105 further, judged whether camera 1 is switched to the focus lock pattern.For instance, but camera 1 display reminding window among the step S105, and whether suitable, allow the user decide in its sole discretion and whether enter the focus lock pattern if using the present focusing state of inquiry user.In another embodiment, step S105 also can be judged voluntarily and determined whether switch to the focus lock pattern by microprocessor 14.
If step S105 is judged as and is, be that camera 1 enters the focus lock pattern, but microprocessor 14 execution in step S106 are locked in this first focal length value with the photography focal length of camera 1, make camera 1 can continue first focus target (in this example in be butterfly 101) of clearly shooting in the frame f1 that sets the goal.Make other alter operation or satisfy predetermined condition up to the user, make camera 1 break away from focus lock pattern or interruption video recording.
On the other hand, if step S105 is not judged as not, promptly camera 1 does not enter the focus lock pattern, and in this embodiment, but microprocessor 14 execution in step S107 switch to autofocus mode with camera 1, determines the focal length of photographing in the mode of dynamic calculation.
What should be specified is, the focus lock pattern of above-mentioned camera 1 is for solving in the shooting process, the influence of rocking because of other object in the shooting picture, cause of the continuous variation of the shooting picture of camera 1 under autofocus mode because of focal length value, producing shooting picture has the effect picture of automatic focusing (clear (focusing) → fuzzy (zoom) → clear (focusing)), and destroys the desired continuous pictures of user.Under autofocus mode, its in time, the variation of picture, microprocessor 14 just rejudges theme object possible in the whole image at set intervals, and calculate formation " autofocus frame " automatically and aim at possible theme object, use calculating automatic focal length value and adjusting the photography focal length.For example, when the focusing flow process (step S100 is to step S104) that the user makes by oneself is finished and focused behind first focus target (butterfly 101), but do not enter the focus lock pattern but be in autofocus mode, after a period of time, trees 103 erroneous judgements of rocking in background at the camera 1 of autofocus mode are the theme of picture, and transfer trees 103 are focused automatically, so shooting picture because of the continuous variation of focal length value, produces the effect picture that shooting picture has automatic focusing.Focus lock pattern among the present invention can be locked in the photography focal length of camera 1 first focal length value of corresponding butterfly 101, makes camera 1 can continue clearly first focus target (butterfly 101) of shooting in the frame f1 that sets the goal.
Camera 1 and photographing setting control method also can comprise other application function except setting in order to produce suitable focusing in this embodiment.See also Fig. 5, Fig. 5 illustrates the method flow diagram according to the performed photographing setting control method of camera in another specific embodiment of the present invention 1.
As shown in Figure 5, camera 1 and photographing setting control method are except setting (step S200, step S202, step S204 and step S205 to S207) in order to produce suitable focusing in this embodiment, its flow process is roughly the same with the detailed description of previous embodiment, does not give unnecessary details in addition at this.But in the above-mentioned flow process, the frame f1 that sets the goal certainly that the present invention produced is not limited in the photography focal length that is used for adjusting camera 1.
In the embodiment of Fig. 5, after the frame f1 that sets the goal certainly among the step S200 forms, but microprocessor 14 execution in step S201 judge whether to enter the aperture adjustment modes.If step S201 is judged as and is, then the further execution in step S203 of microprocessor 14 according to the calculating of the picture light and shade among the frame f1 that sets the goal certainly f-number, and uses the adjustment photographic aperture.For instance, can be averaged, get median or specific weighted calculation by the brightness value of each pixel that contains among the frame f1 that sets the goal certainly, learn that behind the brightness calculation result of the frame f1 that sets the goal this microprocessor just can produce suitable f-number with lookup table mode or specific calculation method by this.This microprocessor 14 sees through the photographic aperture that this aperture unit is adjusted this camera 1 according to this f-number.After the aperture adjustment is finished among the step S203, then can get back to step S202 and carry out other follow-up flow process.
On the other hand,, then can directly be advanced into step S202, carry out follow-up focal length and adjust flow process if step S201 is judged as not.
Thus, camera 1 of the present invention and photographing setting control method just can allow the user can specify the focus target that desire is taken in the mind voluntarily, to form according to the position of user's touch-control corresponding from the frame f1 that sets the goal, by this can be in order to settings such as the photography focal length of adjusting camera 1 and photographic apertures.
In addition, camera 1 of the present invention can further comprise mode switch assembly 16, and mode switch assembly 16 can be the switching key of entity, and this entity switching key can couple (as shown in Figure 1) with microprocessor 14.Or in another embodiment, the mode switch assembly also can be the switching icon of realizing with software mode (can be presented on the contact panel 10).
When camera 1 is in the focus lock pattern, and when microprocessor 14 execution in step S206 are locked in first focal length value with the photography focal length of camera 1, but microprocessor 14 execution in step S208, when user's operator scheme changeover module 16, but microprocessor 14 execution in step S207 make camera 1 disengaging focus lock pattern and switch to autofocus mode.On the other hand, as user not during operator scheme changeover module 16, but 14 execution in step S209 of microprocessor are maintained at the focus lock pattern with this camera 1.
In the foregoing description, camera 1 and photographing setting control method allow the user to specify first focus target that desire is taken in the mind (being butterfly 101 in this example), and in the practical application, the user also can change the target of desire focusing.
For instance, shown in Fig. 4 A, the user originally touched the position of corresponding butterfly 101 (first focus target) on the contact panel 10, and execution in step S200 focuses to butterfly 101 to step S204 in regular turn, and set the photography focal length.
Then, further execution in step S210 monitors the user and whether touches other position on the contact panel 10.For example, change focus target into second focus target (at a distance house 107) by first focus target (butterfly 101) when user's desire.See also Fig. 4 B, Fig. 4 B is illustrated in the operational instances and forms the synoptic diagram of making focusing frame f2 by oneself when the user chooses second focus target.Shown in Fig. 4 B, the user can touch the position in corresponding house 107 on the contact panel 10.At this moment, when step S210 is judged as be, when promptly detecting the position in corresponding house 107 on user's the touching contact panel 10, but the corresponding user's of microprocessor 14 execution in step S212 touching and adjusting from the frame that sets the goal (in shown in Fig. 4 B, being adjusted to) from setting the goal frame f2 position.Then, but execution in step S214 by adjusted this acquisition second focus target (being house 107) among the frame f2 that sets the goal certainly.At last, execution in step S216 recomputates second focal length value according to this second focus target, and uses the photography focal length of adjusting camera 1.In addition, after step S216 finished, also further execution in step S217 judged whether to enter the focus lock pattern.If step S217 is judged as and is, be that camera 1 enters the focus lock pattern, but microprocessor 14 execution in step S218 are locked in this second focal length value with the photography focal length of camera 1, make camera 1 can continue clearly second focus target (house 107) of shooting in the frame f2 that sets the goal, make other alter operation or satisfy predetermined condition up to the user, make camera 1 break away from focus lock pattern or interruption video recording.On the other hand, if step S217 is not judged as not, promptly camera 1 does not enter the focus lock pattern, and in this embodiment, but microprocessor 14 execution in step S219 switch to autofocus mode with camera 1, determines the focal length of photographing in the mode of dynamic calculation.
In addition, in the process of reality video recording, theme in the shooting picture (first or second focus target) may change the position constantly, in case the position change of focus target, the focal length that camera 1 is adopted also may need corresponding adjustment just can obtain best photographic effects.
See also Fig. 6, Fig. 6 is illustrated in the synoptic diagram of another shooting picture P2 in the operational instances, as shown in Figure 6, among the shooting picture P2, first focus target (being the butterfly 201 in the picture) has changed the position of itself, moves to the right side by the left side of picture, make first focus target not be arranged in original frame f1 that sets the goal certainly, at this moment, microprocessor 14 just can be adjusted and make the target frame by oneself, and then makes the adjusted frame f3 that sets the goal certainly aim at first focus target again.Then, microprocessor 14 just can recomputate the 3rd focal length value from the frame f3 that sets the goal according to adjusted, to adjust the photography focal length of camera 1
Wherein, above-mentioned first focus target of working as has left the frame f1 that sets the goal certainly, and then adjusts and produce the actual practice from the frame f3 that sets the goal, and can follow or chase after automatically burnt mode based on the manual touch-control of user.If adopting manual touch-control follows, then the similar above-mentioned steps S210 of flow process is to step S219, by the position of user after according to the change of first focus target, manually touch-control produces from setting the goal frame f3, and its flow process details can illustrate (step S210 is to step S219) with reference to leading portion.In another embodiment, adjust and produce actual practice from the frame f 3 that sets the goal, also can carry out object and chase after burnt scheduling algorithm automatically by microprocessor 14, in general, object chases after burnt calculation automatically can carry out content analysis based on the focus target in the focusing frame, find out a plurality of unique points of focus target, utilize dynamic comparison mode to judge the relatively move vector (motion vector) of each unique point in two different pictures subsequently, and followed this focus target according to the statistics of the vector that relatively moves.Can make this frame that sets the goal certainly follow this first focus target automatically by this, this people by known techniques is known, and does not give unnecessary details in addition at this.
That is to say, the focus lock pattern that camera 1 and photographing setting control method have high-freedom degree and allow the user to make by oneself, and when the focus target position change, can chase after Jiao automatically by microprocessor 14, or by the user once more touch-control specify the latest position of focus target.
In addition, when camera 1 was in the focus lock pattern, if when judging the predetermined condition meet under the particular context, photographing setting control method may command camera 1 broke away from the focus lock pattern and enters autofocus mode or directly interrupt photography.For instance, left when focus target outside the scope of shooting picture, can directly interrupt photography; Or in the focus lock pattern, the user does not carry out touch-control for a long time, or there has not been any focus target in the frame that sets the goal certainly, can break away from the focus lock pattern and enter autofocus mode.
In sum, photographing setting control method of the present invention and camera are except can adopting known autofocus mode, particularly can produce according to user's touching operation from setting the goal frame, camera is focused according to the focus target in the frame that sets the goal, operation by the focus lock pattern, further the photography focal length with camera is locked in the focal length value that draws from the frame that sets the goal, and makes the focusing flow process of camera more increase the user from the elasticity of ordering.
