D1, I
D3... demonstration carry out stipulated number (for example 3 times) respectively.That is, owing to be taken into the live view image I
1And in this live view image I
1In detect the smiling face, image is taken by the company that therefore generates this moment.Then, generated corresponding at a slow speed live view image I taking image according to this company
D1The time, show 3 these corresponding at a slow speed live view image I according to every sequential at a distance from 1/30 second
D1Equally, owing to be taken into the live view image I
3And in this live view image I
3In detect the smiling face, image is taken by the company that therefore generates this moment.Then, generated corresponding at a slow speed live view image I taking image according to this company
D3The time, show 3 these corresponding at a slow speed live view image I according to every sequential at a distance from 1/30 second
D3And because ensuing live view image I
5In face be the face of crying, do not take shadow and handle so do not connect, do not carry out the demonstration of corresponding at a slow speed live view image.Then, be taken into the live view image I
7, because in this live view image I
7In detect the smiling face, image is taken by the company that therefore generates this moment.Then, generated corresponding at a slow speed live view image I taking image according to this company
D7The time, show 3 these corresponding at a slow speed live view image I according to every sequential at a distance from 1/30 second
D7In addition, though here example each corresponding at a slow speed live view image show 3 times situation separately, but can suitably set this numerical value.
Like this; In this execution mode; Do not change actual frame rate of display (30fps), show but carry out 3 times respectively to each corresponding at a slow speed live view image in order, through this processing from the 0th frame; The demonstration of each corresponding at a slow speed live view image is made as 3 times of interval photography (convert into 1/3 speed) at interval to frame rate of display, has realized the demonstration at a slow speed (live view demonstration at a slow speed) of live view image.Generally, frame rate of display can not freely be changed by the characteristic decision of display element (TFT liquid crystal panel 144).Therefore, be to show the demonstration speed reduce on apparent through identical image being carried out repeatedly (being 3 times in this example), show at a slow speed realizing.But, in the time can using the display element of variable frame rate of display, can show that speed realizes showing at a slow speed through reducing.And, differentiate the expression of being taken the photograph body according to the live view image at this moment, a frame that detects the smiling face is as object, and the company of generation takes image and carries out live view demonstration at a slow speed.And, under the situation that the second release shutter 152 is switched on, record in the recording medium 136 as photographs taking image with the corresponding company of corresponding at a slow speed live view image that this moment, picture showed.For example, when in corresponding at a slow speed live view image I shown in Figure 2
D3Demonstration in connected second when discharging shutter 152, be recorded in the corresponding at a slow speed live view image I of generation
D3The time company that uses take image.
Thus; The user is through being set at photograph mode smiling face's detecting pattern; Can watch the corresponding at a slow speed live view image that only shows at a slow speed with the slow speed of the motion of being taken the photograph body than reality on one side, Yi Bian photograph (indication photography opportunity) to the frame that detects the smiling face.Here, only show that the frame that detects the smiling face is because can imagine that the frame of mirroring the smiling face is shutter opportunity to the user.But, be not limited to the smiling face, also can implementing at a slow speed to the frame that detects other expressions, live view shows.In this case, as long as suitably set desired expression.Therefore, have such effect: even under the fast situation of the motion of being taken the photograph body, also can reliable recording and can not miss shutter opportunity.
In addition, under this smiling face's detecting pattern,,,, carry out 3 times respectively continuously and show to taking the corresponding at a slow speed live view image that image generates according to connecting just according to every display timing generator at a distance from 1/30 second as long as detect face.Therefore, it is long and be consecutively detected under smiling face's the situation to discharge state duration that shutter 151 is switched on first, and the quilt that manifests in the display frame is taken the photograph between the shot object image of body and reality deviation is taken place.Therefore, in this execution mode, take the photograph under the situation that body changes being taken aim at by the user to the quilt of shooting object, eliminate this deviation through live view image is at a slow speed shown to reset.For example, in this execution mode, be presumed to input during zoom operation by the user and take aim at when taking the photograph body and change for the quilt of shooting object, the image live view demonstration at a slow speed of resetting with corresponding at a slow speed live view image is taken by the company that deletion has generated.And, discharging under the situation that shutter 151 is disconnected first, the quilt of also supposing the user and being taken aim at is taken the photograph body variation has been taken place.In this case, image and corresponding at a slow speed live view image are taken by the company that generated of deletion, turn back to common live view then and show, discharge shutter 151 by connection once more and in the live view image, detect the smiling face up to first.
The action of explanation camera 1 below.Fig. 3 is the flow chart of the elemental motion of expression camera 1.In camera 1, when indicating energized when having operated the not shown power knob that constitutes key matrix 150, beginning is supplied power to various piece by power circuit 173.Then, as shown in Figure 3, at first, systems control division 111 carries out the initialization of internal circuit etc., sets the operational environment (step a1) of camera 1.Then, get into photograph mode, for example every processing that repeated step a3～step a19 at a distance from 1/30 second.
Under photograph mode, at first, systems control division 111 is judged the setting of photograph mode.Under the situation that is set to the photograph mode beyond common photograph mode etc., the smiling face's detecting pattern (step a3: " denying "); Get into common live view image display status (live view shows usually), make TFT liquid crystal panel 144 continue to carry out the demonstration (step a5) of live view image.Promptly; Systems control division 111 whenever repeated following a series of processing at a distance from 1/30 second; That is: the view data that images in the shot object image on the imaging apparatus 102 for example is interrupted reads processing; Its blotter in frame memory 133, and is presented at it on TFT liquid crystal panel 144 as the live view image.Here, so-called live view image is meant the view data that is taken in real time from image pickup part.Through the processing here, the view data of shot object image is shown with the frame rate of display (being 30fps here) of regulation in real time continuously, realizes that common live view shows.
Then, systems control division 111 carries out photograph processing (step a7).In this photograph processing, systems control division 111 discharges first controls the AF action when shutter 151 is switched on.Thus, camera 1 is carried out the focusing action, remains on focusing state (AF locking).Then, systems control division 111 moves in the photography of the time point control image pickup part that the second release shutter 152 is switched on, and the control exposure is carried out whole pixels of view data and read processing.Thus, generate second the view data of camera coverage when discharging shutter 152 and being switched on, with its as the view data blotter of photographs in frame memory 133.This view data is recorded in the recording medium 136 after implementing necessary image processing by image processing part 120.
On the other hand, under the situation that is set to smiling face's detecting pattern (step a3: " being "), change live view associative mode processing (step a9) at a slow speed over to.
And, under photograph mode, to have imported under the situation of setting operation of photograph mode (step a11: " being ") through key matrix 150, systems control division 111 carries out the mode initialization change handles the setting (step a13) of change photograph mode.For example, systems control division 111 is carried out and is shown processing, as menu screen, on TFT liquid crystal panel 144 or LCD panel 162, shows the setting menu of mode of operation or the various menu items such as setting menu of photography conditions.Then,, carry out and selected menu item corresponding processing, carry out the setting menu of mode of operation, the setting/change of photography conditions etc. according to operation input to key matrix 150.What carry out here is the setting of common photograph mode or photograph modes such as smiling face's detecting pattern and Portrait.
And; When the switching indication of having imported mode of operation through key matrix 150 is set at reproduction mode (step a15: " being "); Change reproduction processes over to, for example carry out following processing (step a17):, confirm to reproduce the photographs of object according to operation input to key matrix 150; From recording medium 136, read its view data, with its demonstration (reproduction) on TFT liquid crystal panel 144 or external image display unit 201.
Then, in step a19, keep watch on the dump indication, indicated by operation at power knob under the situation of cut off the electricity supply (power-off) (step a19: " being "), finish elemental motion.In this case, stop the power supply of power circuit 173 to various piece, camera 1 changes the dump state over to.If power supply is not closed (step a19: " denying "), then return step a3.
The associative mode of live view at a slow speed of step a9 in the following key diagram 3 is handled.Fig. 4 representes the flow chart of the detailed process step of live view associative mode processing at a slow speed.In the associative mode of live view at a slow speed of this execution mode was handled, as shown in Figure 4, at first, systems control division 111 judged that first discharges the making operation of shutter 151.If be not switched on (step b1: " denying "), then according to Fig. 3 in the identical main points of step a5, carry out common live view and show, that is, carry out real-time pictures and show (step b3) imaging in shot object image on the imaging apparatus 102.Then, return the step a9 among Fig. 3, change step a11 over to.
On the other hand, under the situation that the first release shutter 151 is switched on (step b1: " being "), during the state that is switched on, every processing that repeated step b5～step b41 at a distance from 1/30 second.
That is, at first, systems control division 111 carries out initialization process (step b5).In this execution mode; Systems control division 111 is set at initial value " 0 " with following each value respectively, that is: expression connect the frame number of taking image count value n, represent the count value t of frame number of count value x and the corresponding at a slow speed live view image that is used for obtaining to show of the frame number of corresponding at a slow speed live view image.At this moment, systems control division 111 carries out the control of AF action, and camera 1 becomes the state of AF locking.
Then, be taken into the live view image and carry out face recognition processing (step b7).For example, at first, 111 pairs of shot object images that image on the imaging apparatus 102 of systems control division are interrupted reads processing.Then, according to the result of this moment, the image recognition portion live view image of 124 pairs of blotters in frame memory 133 carries out face recognition to be handled.That is, the view data of the live view image that is taken into of 124 pairs in image recognition portion is carried out face detection and is handled.Then, smiling face's test section 125 is differentiated the expression of the face that comprises in the live view image according to the face detection result.
And when detecting the smiling face in the live view image that smiling face's test section 125 is being taken into (step b9: " being "), then, systems control division 111 connects takes shadow processing (step b11).That is, the photography action of systems control division 111 control image pickup parts, the control exposure is carried out whole pixels of view data and is read processing.The result; Under the photograph mode that is set to smiling face's detecting pattern; First discharge state that shutter 151 is switched on down and detect in the live view image that is taken at this moment the smiling face during, every image that generated camera coverage at this moment at a distance from 1/30 second is as even taking image.And, the view data that image processing part 120 is taken image according to the company that generates among the step b11, the view data (step b13) of the corresponding at a slow speed live view image of generation.For example, pixel count is according to the rules taken image and is interrupted and is taken into processing connecting, and generates corresponding at a slow speed live view image.
In addition, at this moment, systems control division 111 is notified count value n to image processing part 120 as frame number.Company's shooting image of the n frame that image processing part 120 will obtain and corresponding at a slow speed live view image are mapped with the frame number of being notified by systems control division 111 and record in the record buffer memory device 134.For example, if in step b9, be judged to be " being " at first, then frame number is " 0 ", in step b7, generates the company's shooting image as the 0th frame of beginning, in step b9, generates the corresponding at a slow speed live view image of the 0th frame.
Then, systems control division 111 increases by 1 respectively with count value n and count value t and upgrades (step b15), and frame rate of display converter section 123 will go among the x to upgrade (step b16) divided by 3 Shang dynasties of obtaining with the count value t after upgrading.Then, frame rate of display converter section 123 from record buffer memory device 134, read with the value of x as frame number and with it corresponding at a slow speed live view image of corresponding x frame, be presented at (step b17) on the TFT liquid crystal panel 144.
Then; Systems control division 111 judges that second discharges the making operation of shutter 152; If be switched on (step b19: " being "); Then with show in company's shooting image of the corresponding x frame of the frame number of corresponding at a slow speed live view image, be recorded in (step b21) in the recording medium 136 as photographs.
And if the second release shutter 152 is not switched on (step b19: " denying "), systems control division 111 judges that first discharges the opening operation of shutter 151.And; Under the situation that the first release shutter 151 is disconnected (step b23: " being "); Systems control division 111 carries out the company that generated of deletion record in record buffer memory device 134 and takes image and corresponding at a slow speed live view treatment of picture (reset and handle), and resetting at a slow speed, live view shows (step b25).At this moment, the state of AF locking is disengaged.Then, return the step a9 among Fig. 3, change step a11 over to.
On the other hand, discharge the state (step b23: " denying ") that shutter 151 is switched on if be in first, then, systems control division 111 detects zoom operation (operation of zoom button 153) (step b26).And, in step b26, detect under the situation of zoom operation (step b27: " being "), change the step b41 of back narration over to, 111 pairs of systems control divisions live view at a slow speed show and reset.Then, return step b5 and carry out initialization process, the face recognition that changes next frame over to is handled.On the other hand, not detecting (step b27: " denying ") under the situation of zoom operation, return step b7, the face recognition that changes next frame over to is handled.
And, be in the live view image, not detect under smiling face's the situation (step b9: " denying ") in the face recognition process result of step b7, systems control division 111 is judged count value n.And; At count value n is under the situation of " 0 ", that is, be switched on and do not detect a smiling face and do not connect under the situation of taking the shadow processing (step b28: " being ") discharging shutter 151 from first; Systems control division 111 according to Fig. 3 in the identical main points of step a5; Carry out common live view and show, that is, the shot object image that images on the imaging apparatus 102 is carried out real-time pictures demonstration (step b29).
Then, systems control division 111 judges that second discharges the making operation of shutter 152, under situation about being switched on (step b31: " being "), and the photography action (step b33) of control image pickup part.That is, systems control division 111 control exposures are carried out whole pixels of view data and are read processing.Thus, generate the view data of the camera coverage of this moment, as the view data of photographs, this view data is recorded in the recording medium 136 after having implemented necessary image processing by image processing part 120.Then, return the step a9 among Fig. 3, change step a11 over to.
In addition, if the second release shutter 152 is not switched on (step b31: " denying "), then systems control division 111 judges that first discharges the opening operation of shutter 151.And, under the situation that the first release shutter 151 is disconnected (step b35: " being "), return the step a9 among Fig. 3, change step a11 over to.On the other hand, if the first release shutter 151 is not disconnected (step b35: " denying "), return rapid b7, the face recognition that changes next frame over to is handled.
In addition, not (step b28: " denying ") under the situation of " 0 " at count value n, judge whether count value n is consistent with count value x.Here, count value n and count value x is inconsistent is meant, the frame number of the corresponding at a slow speed live view image in the final frame number that image is taken by the company that has generated and the demonstration is inconsistent.Therefore, in the corresponding at a slow speed live view image of each frame that has generated, include the corresponding at a slow speed live view image that does not show of mirroring smiling face personage.Therefore, proceed live view demonstration at a slow speed, till having shown all corresponding at a slow speed live view images that do not show.That is, (step b37: " denying ") changes step b16 under count value n and the inconsistent situation of count value x, transfers to the demonstration of the corresponding at a slow speed live view image of next frame.
And under the count value n situation consistent with count value x (step b37: " being "), systems control division 111 judges that first discharges the opening operation of shutter 151.And, under the situation that the first release shutter 151 is disconnected (step b39: " being "), changing step b25 over to, systems control division 111 live view at a slow speed shows replacement.Then, return the step a9 among Fig. 3, change step a11 over to.
On the other hand, under the situation that the first release shutter 151 is not disconnected (step b39: " denying "), systems control division 111 is live view demonstration replacement (step b41) at a slow speed also.At this moment, the company that has generated the shooting image and the corresponding at a slow speed live view image that are recorded in the record buffer memory device 134 are deleted.In this case, return step b5 and carry out initialization process, the face recognition that changes next frame over to is handled.
That kind as described above; According to this execution mode; Discharge shutter 151 first and be switched on and in the live view image, detect under smiling face's the situation, can begin and connect to take the shadow processing, and can use company's shooting image of generation to carry out live view demonstration at a slow speed.Thus, first discharge that shutter 151 is switched on during, only the frame that detects the smiling face as object, the view data of for example taking image with interval photography (for example every) company of generation of regulation at a distance from 1/30 second.Then, the view data that can use this company to take image is carried out live view demonstration at a slow speed, carries out being taken the photograph the picture demonstration of body with the slow speed of the motion of being taken the photograph body than reality.And, discharge the time point that shutter 152 is switched on second, can write down the view data of the company's shooting image that carries out the picture demonstration.Therefore, has such effect:, also can write down reliably and can not miss shutter opportunity even under the fast situation of the motion of being taken the photograph body.
