Imaging apparatus 5 has a plurality of pixels and is the shooting face that two-dimentional shape is arranged, and has the different a plurality of colored filters that form predetermined periodic arrangement (for example, Bayer (Bayer) is arranged) in the front of this shooting face.This imaging apparatus 5 is known interline type CCD solid-state imagers.The vertical complete configuration of row that transmits CCD (VCCD) and photodiode, VCDD is connected with the horizontal transmission CCD (HCCD) that is configured in the imaging apparatus bottom.

Having carried out the signal charge after the opto-electronic conversion by the photodiode of each pixel that constitutes imaging apparatus 5 is accumulated in each junction capacitance through electric charge accumulation action.When accumulation period (between exposure period) finishes, apply shift pulse to transmitting grid (TP), be accumulated in electric charge in the junction capacitance of each pixel and be displaced to and whole pixels VCCD of adjacency simultaneously.When having read signal charge, photodiode is in bias state once more, can carry out the accumulation of signal charge.Synchronously be sent to the below by signal charge that VCCD read and the clock pulse that imposes on the carry electrode of VCCD.In the moment that is sent to bottom, the signal charge of the delegation of delegation of VCCD is sent to HCCD, and is sent to the output of HCCD successively.The signal charge that is sent to the output of HCCD is read into the outside of imaging apparatus via the output circuit that comprises FD (Floating Diffusion, the diffusion of floating) or amplifying circuit.When having read the signal charge of a picture, VCCD is in dummy status, can read the ensuing signal charge that is accumulated in the photodiode once more.

As imaging apparatus 5, adopt known longitudinal type to overflow the CCD solid-state imager of structure.This imaging apparatus constitutes: at surperficial formed p type diffusion zone (the p trap: constitute photodiode (PD) p-well), utilize the anti-bias voltage Vsub between p trap and the n type substrate that the p trap is exhausted fully of n type substrate (for example, n type silicon substrate).Through applying high voltage pulse, can the electric charge that be accumulated in the photodiode be discharged to substrate-side as this anti-bias voltage Vsub.Therefore, through controlling this anti-bias voltage Vsub, can control the charge accumulation time of photodiode.

In addition, in this execution mode, suppose the cameraman when observation is presented at the image on the display part 18, be used to take the releasing operation (operation of closed the 2nd release-push 21b) of the shot object image of expectation.

Below, the action of the digital camera that this execution mode relates to is described.

When detecting the 1st release-push 21a by CPU 20 when moment tr1 is closed,, calculate the f-number and the time for exposure (Texp) of aperture 3 according to light value through AE handling part 14.Then, according to this f-number stop down 3 (aperture control).And, calculate the relevant information of the distance of being taken the photograph body through AF handling part 16, according to the relevant information of taking the photograph the distance of body to this quilt,, regulate the focus condition (AF control) of pick-up lenss 1 via lens drive system 2 through the control of CPU 20.And, when detecting the 1st release-push closure, applying the high voltage pulse as anti-bias voltage Vsub of imaging apparatus 5, the electric charge that is accumulated in the photodiode is discharged to substrate-side.

When aperture control and AF control end, through stopping to apply high voltage pulse, the exposure of beginning imaging apparatus 5 (the electric charge accumulation of photodiode) as anti-bias voltage Vsub.When beginning from exposure through Texp time to end exposure, transmit pulse (TP) through applying, the electric charge that is accumulated in the photodiode is sent to vertical CCD (VCCD).The electric charge that is sent to VCCD is read control through known, is read as view data from imaging apparatus 5.This view data of reading is carried out predetermined process by CDS circuit 8, amplifying circuit 9, A/D converter section 10 and image processing part 13, temporarily is stored in the internal memory 12 that can carry out high speed motion as DID afterwards.Next, detect the 2nd release-push 21b closure by CPU 20 before, begin to repeat the shooting action of view data to internal memory 12 stored from the accumulation of the electric charge of above-mentioned photodiode.Here, the time that applies as high-tension time (Tsub) of anti-bias voltage Vsub and (Texp) addition of ensuing time for exposure gained becomes frame period Tf.

In addition; Because the memory capacity of internal memory 12 is not unlimited; Thereby whenever in internal memory 12 stored during the view data of predetermined volumes; CPU 20 just carries out the address control of internal memory 12 and the timing controlled of image data storage, so that begin to rewrite once more view data and storage from the memory address of original stored.When view data is circulated, rewrite storage like this in the internal memory 12 of limited capacity, can repeat and the efficient view data of storing predetermined frame number well with the capacity of less internal memory 12.Then, read the view data that temporarily is stored in the internal memory 12 and it is presented on the display part 18 one by one.Then, select desired image the image on being presented at this display part 18, with the expression this desired image Imagery Data Recording in dismantled and assembled memory 17.

Below, specify the action of this execution mode with reference to the sequential chart of Fig. 2.

Internal memory 12 has the memory capacity of the such view data of storage at least; This view data is that the moment tr3 of response time τ m is a benchmark to begin in advance from the moment tr2 that detects the 2nd release-push 21b closure through CPU 20, captured view data during the moment tb that is stored in the time Δ t2 (Δ t2 >=τ m) in the nonvolatile memory 19 in advance to lagging behind from the moment ta that is stored in advance the time Δ t1 (Δ t1 >=τ d) in the nonvolatile memory 19 in advance.Wherein, τ d is reading the view data that is stored in the internal memory 12, and time before being presented on the display part 18 of the image of the pictorial data representation that will be read by this (below be called " display delay time ").Then, before the operation that detects closed the 2nd release-push 21b, begin circularly view data to be rewritten storage successively from the memory address that records view data at first.

Specifically; The central authorities of time for exposure Texp the view data in being stored in internal memory 12, that this view data relates to constantly near the central authorities of the view data (DATAm) of ta constantly time for exposure Texp in the view data that is stored in the internal memory 12, that this view data relates to constantly near the view data of the view data (DATAk) of tb constantly, temporarily be stored in the internal memory 12.In addition, the value of above-mentioned Δ t1 and Δ t2 can be selected arbitrarily through cameraman's operation.

Because response time τ m is the time that begins from the vision capture through the cameraman to (identifying) shot object image to detecting till the releasing operation that is used to take this shot object image, thereby the image that the cameraman wants to take is to be presented at the image (being DISPn in the example at Fig. 2) on the display part 18 at the moment tr3 that shifts to an earlier date response time τ m than the moment tr2 that is detected the 2nd release-push 21b closure (releasing operation) by CPU 20.Be illustrated in view data that above-mentioned moment tr3 is presented at the image on the display part 18 and be the view data (being DATAn the example at Fig. 2) of reading from internal memory 12 at the moment tr4 of display delay time τ d in advance.Can't say certainly that this view data (DATAn) is that the possibility of the corresponding view data of the image wanting most to take with the cameraman is high.

Therefore; In this execution mode; After the indication of having carried out being used for shot image data is recorded in the dismantled and assembled memory 17; In temporarily being stored in internal memory 12 from moment ta to moment tb during the captured view data, preferentially read and be the high view data of the possibility of view data of the expression cameraman image wanting most to take and it is presented on the display part 18.In addition, call over and be presented at which type of on the display part 18 about the view data that will temporarily be stored in the internal memory 12, the back will be elaborated with reference to the flow chart that the view data of Fig. 4 is selected.

Below, comprise the shooting motion flow of digital camera of the image capture method of this execution mode with reference to flow chart explanation shown in Figure 3.

At first, CPU 20 judges the 1st release-push 21a whether closed (step S301).When detecting the 1st release-push 21a when closed, through AE handling part 14, according to the f-number and the time for exposure (Texp) of light value computing aperture 3.Then, according to this f-number stop down 3 (step S302).Then, calculate the relevant information of the distance of being taken the photograph body,,, regulate the focus condition (step S303) of pick-up lens 1 via lens drive system 2 through the control of CPU 20 according to the relevant information of taking the photograph the distance of body to this quilt through AF handling part 15.

Then; Control according to anti-bias voltage Vsub; During the time for exposure Texp that calculates through step S302, carry out the electric charge accumulation of photodiode; Read the electric charge in the photoelectric conversion part that is accumulated in imaging apparatus from imaging apparatus 5 afterwards, the enforcement prearranged signal is handled and is converted DID (step S304) to.View data captured in step S304 temporarily is stored in (step S305) in the internal memory 12 subsequently.Then, CPU 20 judges the 2nd release-push 21b whether closed (step S306).When being judged as the 2nd release-push 21b when not closed, get back to step S304, the action that repeats shooting (step S304) and image data storage (step S305) is closed up to the 2nd release-push 21b.

When in step S306, detecting the 2nd release-push 21b when closed, then CPU 20 judges whether the 1st release-push 21a and the 2nd release-push 21b break off (step S307).This be because: select in the step (step S308) in subsequently view data and since with the 1st release-push 21a with after definite key of stating use simultaneously, thereby be necessary to remove for the time being the releasing operation that so far carries out.When in step S307, being judged as the 1st release-push 21a and the 2nd release-push 21b when breaking off, then the carries out image data are selected the subprogram (step S308) handled.

Below, with reference to the structure of the image selection 21d of portion in Fig. 6 description operation portion 21.

Judge whether then to have carried out reset (step S409).Under situation about resetting, get back to step S403, repeat the action of above explanation.Like this; When pressing options button 26b; Just from internal memory 12 successively (being the order of DATAn+1 → DATAn+2 → DATAn+3... in the example of Fig. 2) read out in and taken captured view data C after the view data A, with image one frame one frame of correspondence be presented on the display part 18.

Supress (step S403) when confirming key 25 when in step S403, detecting by CPU 20; Under the control of CPU 20; Be illustrated in this view data that is presented at the image on the image displaying part 18 constantly and be compressed/decompress 16 compressions as required, be recorded in afterwards in the dismantled and assembled memory 17 (step S404).When the processing of step S404 finishes, return from illustrated subprogram.

In addition; In above explanation, when supressing when confirming key 25, with being illustrated in this Imagery Data Recording that is presented at the image on the image displaying part 18 constantly in dismantled and assembled memory 17; Yet can show the affirmation message that whether is recorded in the dismantled and assembled memory 17 as required.This is because have misoperation.

Then, get back to the explanation of the flow chart of Fig. 3, finish a series of shooting actions.

Below, the mensuration of the response time in the digital camera that reference this execution mode of flow chart detailed description shown in Figure 5 relates to.

When the cameraman has carried out operation to the predetermined switch of operating portion 21 and when switching to the mode determination of response time, at first, be stored in the memory [n] of the mensuration frequency n that is used for memory response time of delay (step S501) 0.Here, suppose that [x] expression is used for the memory of storage of variables x.

Then, CPU 20 makes timer conter 20a reset (step S502).Then, CPU 20 judges the 1st release-push 21a whether closed (step S503).When in step S503, detecting the 1st release-push 21a closure, then 20 couples of timer conter 20a of CPU measure the setting (step S504) with the Displaying timer of image.This mensuration is the particular image that shows for the response time of measuring the cameraman with image.For example, in the demonstration of landscape image, may occur flyer suddenly, also may occur and the diverse mark of normal image.Perhaps, can carry out countdown or counts, when having shown predetermined number, supervise releasing operation the numeral that is presented on the display part 18.

Then, in order to measure response time τ m, the demonstration of the dynamic image of on the display part of being located at the digital camera back side 18, being scheduled to, and timer conter 20a begins counting (step S505).Then, CPU 20 judges from the counting of beginning timer conter 20a whether passed through the mensuration that among step S504, the sets Displaying timer (step S506) with image.When in step S506, being judged as when reaching the Displaying timer of measuring with image, on display part 18, measure demonstration, and timer conter 20a is resetted and begin to count (step S507) with image by CPU 20.

Then, CPU 20 judges the 2nd release-push 21b whether closed (step S508).When in step S508, being judged as the 2nd release-push 21b when closed, then stop the counting (step S509) of timer conter 20a.That is, in timer conter 20a, preserve among step S507, show measuring and begin the response time τ m till the 2nd release-push 21b closure with image.This time equals to go out predetermined image from the cameraman through visual identity and begins to the response time that is detected by CPU 20 till the 2nd release-push 21b closure.

Then, CPU 20 is stored in n+1 in the memory [n] of the mensuration number of times that is used for memory response time of delay (step S510).Then, CPU 20 response time that will in step S408, remain in the timer conter temporarily is stored in (step S511) in the memory as τ m (n).Then, CPU 20 will " continue? be that message not " is presented at (S512) on the display part 18.Then, CPU 20 judges whether that by the operator predetermined switch of operating portion 21 having been carried out operation has selected " being " or " denying " (step S513).

Then, CPU 20 judges in step S513, whether to have selected " being " (continuing to measure) (step S514), being judged as under the situation of having selected " being ", get back to step S502, repeat above-described action.Then, CPU 20 computings are stored in response time τ m (1), τ m (2), the τ m (3) in the memory ... the mean value τ m of τ m (n), and it is stored in the memory [τ m] (step S515).Finish the mensuration of response time.

In this execution mode, will begin from the vision capture through the cameraman to shot object image to be stored in advance in the nonvolatile memory 19 to the relevant information that detects the response time τ m till the 2nd release-push 21b closure that is used to take above-mentioned shot object image.Then; From repeating before to take and temporarily be stored in the multiple image data internal memory 12 in detecting the 2nd release-push 21b closed (releasing operation), the moment that option table is shown in than detects above-mentioned the 2nd release-push 21b closure shifts to an earlier date the view data A that above-mentioned response time τ m is presented at the image A on the display part 18.Then after image A being presented on the display part 18; Before the moment of having taken image A captured image B, or taken the moment of image A after captured image C according to the shooting of these images constantly near the order in shooting moment of image A, when carrying out the scheduled operation of the image selection 21d of portion, show with regard to a frame one frame ground.Therefore, ability selected best scene simple and reliablely and it is recorded in the recording medium.

And, in this execution mode, on the image selection 21d of portion, clip release-push 21a (confirming key 25) and dispose a pair of options button 26a, 26b.On display part 18, when an options button in using a pair of options button 26a, 26b carries out selection operation, just show above-mentioned image B near the shooting order one frame one frame ground constantly of above-mentioned image A constantly according to shooting.And, when another options button in using above-mentioned a pair of options button is selected to move, just show above-mentioned image C near the shooting order one frame one frame ground constantly of above-mentioned image A constantly according to shooting.Then, when supressing the definite key 25 that uses simultaneously with the 1st release-push 21a, the view data that expression is presented at the image on the display part 18 is stored in the dismantled and assembled memory.Therefore, operability is good, can successfully make a video recording → operation of image selection → image record.

And; In this execution mode; Owing to be provided with the response time determination part; Time till this response time determination part is measured from beginning with image in the predetermined response time mensuration of display part 18 demonstrations to detecting the 2nd release-push 21b closure, thereby can measure the intrinsic response time information of cameraman simply.

And; In this execution mode; On display part 18, show such image; This image is that the closed moment shifts to an earlier date image view data, that captured multiple image data are represented respectively in the predefined time that above-mentioned response time τ m is presented at the image on the display part 18 than detecting the 2nd release-push 21b to comprise expression by in the multiple image data that are stored in the above-mentioned internal memory 12.Therefore, can make scene is that the highest image efficient of possibility of cameraman's scene of wanting to take well and reliably is included in the multiple image that this display part 18 shown.

And; In this execution mode; On display part 18, show such image; This image is by in the multiple image data that are stored in the above-mentioned internal memory 12, comprises expression and shift to an earlier date above-mentioned response time τ m than moment of the closure that detects the 2nd release-push 21b to be presented at the image that view data view data, predefined frame number of the image on the display part 18 is represented respectively.Therefore, can be that the highest image of possibility of cameraman's scene of wanting to take is included in the multiple image that this display part 18 shown simple and reliablely with scene.

And; In this execution mode; Internal memory 12 has to be stored in has at least taken the memory capacity of expression as the view data of frame number captured before the moment of the view data of hypograph, and wherein this image is to begin to be presented at the image on the display part 18 to the moment that shifts to an earlier date above-mentioned response time τ m from detecting the moment of having carried out releasing operation.Therefore, can be in the moment that shooting finishes, will be stored in reliably in the internal memory 12 from detecting the view data that the moment of having carried out releasing operation begins to shift to an earlier date above-mentioned response time τ m.

[the 2nd execution mode]

Specify the 2nd execution mode with reference to the accompanying drawings.

This execution mode be via optical finder (below be called " OVF " (Optical ViewFinder) and observe by the digital camera of an example of the camera head of making a video recording when taking the photograph body.This digital camera is after having taken multiple image continuously; With this multiple image one frame one frame be presented on the display part; Select the image of the best scene of expectation the image on being presented at this display part, with the image data storage of correspondence in dismantled and assembled memory.Other are identical with the 1st execution mode.

Figure 10 is the block diagram as the structure of the digital camera of an example of camera head that illustrates that this execution mode relates to.Enclose same numeral to having with the component part of Fig. 1 identical function.In following explanation, the aspect different with the 1st execution mode only described.

As the structural portion that has with Fig. 1 different functions, the digital camera that this execution mode relates to has OVF, and this OVF is made up of moving reflector 27, punt glass 28, ridge pentaprism 29 and eyepiece 30.

Moving reflector 27 is in the shooting preparatory stage, and the light beam from being taken the photograph body that has been used for transmission pick-up lens 1 is directed to OVF.Moving reflector 27 moves to the position that the dotted line of Figure 10 is represented in shooting.Thus, transmission the light beam of pick-up lens 1 in shooting, be directed into imaging apparatus 5.Punt glass 28 is configured in the focusing position of pick-up lens 1 and forms shot object image.Ridge pentaprism 29 is to be used for being formed on shot object image on the punt glass 28 is directed to cameraman's eye as erect image via eyepiece 30 prism.In addition, the structure of display part 18 is identical with the 1st execution mode, yet in this execution mode, owing to when being taken the photograph body via the OVF observation, make a video recording, thereby the shot object image in the shooting is not presented on the display part 18.

Below, the action of this execution mode is described with reference to the sequential chart of Figure 11.

In this execution mode, the desired image that the cameraman wants to take is that the cameraman is via the observed shot object image of OVF.Therefore, the method according to the view data of the desired image of selecting the expression cameraman to want the view data of response time τ m in being stored in internal memory 12 to take is different with the 1st execution mode.Because other are identical with the 1st execution mode, thereby in following explanation, its different aspect only are described.

Because response time τ m takes the photograph body to begin time of being used to take till this quilt is taken the photograph the releasing operation of body to detecting from the vision capture through the cameraman to the quilt of wanting to take; Thereby the image that the cameraman wants to take is such image; This image is than the captured image (in the example of Figure 11, being DATAn) of the moment tr2 τ pre-set time m ' that is detected the 2nd release-push 21b closed (releasing operation) by CPU 20 (below be called " response time τ m ' "), this time τ m ' be make response time τ m add from begin to take taken the photograph body to will the time τ i till captured image data storage is in internal memory 12 (below be called " delay time T of making a video recording i ") and time of obtaining.

Because the shooting of the digital camera in this execution mode action is basic identical with the 1st execution mode; Thereby in following explanation; When selecting the flow chart of motion flow, be that the center describes with the aspect different with the 1st execution mode with reference to the view data that digital camera is shown of Fig. 4.

In Fig. 4; At first; Through CPU 20, from internal memory 12, read central authorities in the view data that is stored in the internal memory 12, time for exposure Texp constantly near shifting to an earlier date the view data A (in the example of Figure 11, being DATAn) (step S401) of the moment tr5 of response time τ m ' than detect moment tr2 that the 2nd release-push 21b closes (releasing operation) by CPU 20.View data A is read from internal memory 12 by following.That is, will the frame period be set at Tf, and the time set that will begin from the storage of the view data in moment tr2 is stored in internal memory 12 (being DATAn+2) till the moment tr2 is Δ tr among Figure 11, computing N=" (τ m '-Δ tr)/Tf ".Here, the integer-valued mark after " x " expression computing rounds up to x.View data A is stored in the view data (being DATAn in the example at Figure 11) in the internal memory 12 at moment tr2 to internal memory 12 carries out image stored data (being DATAn+2) in Figure 11 preceding N frame.This view data A (DATAn) is that the possibility of view data of the expression cameraman image wanting most to take is high.

In addition, as view data A, the central authorities of having selected time for exposure Texp are constantly near the view data that shifts to an earlier date the moment tr5 of response time τ m ' than moment tr2, however not necessarily strict demand.Also can for: the moment tr5 that shifts to an earlier date response time τ m ' than tr2 constantly is the moment that time for exposure Texp begins, or time of finishing of time for exposure Texp.In a word, view data is so long as get final product in the captured view data in front and back of the moment tr5 of response time τ m ' in advance.This be because: cameraman's response time has deviation, in this execution mode, is prerequisite with this situation, after shooting, makes view data A preferentially from a plurality of view data, select best scene.

The later handling process of following steps 402 is identical with the 1st execution mode.And in this execution mode, the mensuration of response time τ i is handled also identical with the 1st execution mode.

In this execution mode; In having the digital camera of optical finder, will begin from the vision capture through the cameraman to shot object image to be stored in advance in the nonvolatile memory 19 to the relevant information that detects the response time τ m till the 2nd release-push 21b closure that is used to take above-mentioned shot object image.Then; From temporarily being stored in the multiple image data in the internal memory 12 through repeating to take before detecting the 2nd release-push 21b closed (releasing operation); Select expression and shift to an earlier date the view data A of the captured image of response time τ m ' than detecting the closed moment of above-mentioned the 2nd release-push 21b, the above-mentioned response time τ of this response time τ m ' m adds shooting delay time T i and obtains.Then; After image A is presented on the display part 31; After the moment of having taken image A captured image B, or before the moment of having taken image A captured image C according to the shooting of these images constantly near the shooting order constantly of image A, when carrying out the scheduled operation of the image selection 21d of portion, show with regard to a frame one frame ground.Therefore, ability selected best scene simple and reliablely and it is recorded in the recording medium.

[the 3rd execution mode]

Specify the 3rd execution mode of the present invention below.

In the 1st execution mode and the 2nd execution mode; When detecting the 2nd release-push 21b by CPU 20 when closed; With the view data more than the frame that is stored in the internal memory 12 by predefined procedure one frame one frame read; To be presented at by the image of each pictorial data representation on the display part 18, select desired image the image on being presented at this display part 18, with the Imagery Data Recording of correspondence in dismantled and assembled memory 17.Relative therewith; In this execution mode; Be, will be simultaneously displayed on the display part 18 with the difference of the 1st execution mode or the 2nd execution mode by the image that is stored in the multiple image data representation in the internal memory 12 when detecting the 2nd release-push 21b by CPU 20 when closed; Select desired image the image on being presented at this display part 18, with the Imagery Data Recording of correspondence in dismantled and assembled memory 17.Other are identical with the 1st execution mode or the 2nd execution mode.In the explanation of this execution mode below, only describe and the 1st execution mode or the different aspect of the 2nd execution mode.

Figure 12 is the flow chart that view data that this execution mode is shown select to be handled the motion flow of (the step S308 of Fig. 3).

At first, read the multiple image data that are stored in the internal memory 12 and with its division display (showing dividually) on display part 18 (step S701).Figure 13 and Figure 14 illustrate 3 two field pictures are presented at picture central authorities with the mode of horizontal row state.And the rectangular area on the top of each image is the part of display pointer, through representing to have selected correspondence image with predetermined color to this rectangular area is painted.Here, show illustrated image A in the 1st execution mode or the 2nd execution mode in picture central authorities.And, show the image B of before view data A, just having taken on the picture right side, show the image C of after view data A, just having taken in the picture left side.

Then, and display pointer in the rectangular area 31 on the top of central picture (step S702, Figure 13).This pointer utilizes options button 26a or 26b and the move left and right of Fig. 6.Press options button 26a during, pointer moves at interval with preset time a frame one frame, press options button 26b during, pointer moves on the left of the picture with preset time at interval a frame one frame.In step S703,, judge by CPU 20 whether pointer moves according to aforesaid operations.When being judged as pointer by CPU 20 when moving, then judging whether to supress and confirm key 25 (step S707).

On the other hand, when in step S703, being judged as pointer by CPU 20 when having moved, judge then whether pointer arrives picture end (step S704).When pointer had arrived the picture end, pointer was fixed on the picture end.Arrived at pointer under the state of picture end, when continuing to press options button 26a or options button 26b, through CPU 20 on the direction corresponding with pointer position with a preset time frame one frame ground rolling picture (step S705) at interval.Figure 14 illustrates the state that pointer has arrived the picture right-hand member, and picture rolling is to the left side.According to the direction of picture rolling, the image of being represented by view data B or view data C is presented on the display part 18 according to the order of its shooting moment near the moment of captured image data A.For example, when continuing to press options button 26a, make picture rolling arrive the left side, show in the order of picture end according to DATAn-1 → DATAn-2 → DATAn-3... through CPU 20.And, when continuing to press options button 26b, make picture rolling to the right side through CPU 20, show in the order of picture end according to DATAn+1 → DATAn+2 → DATAn+3....

In step S704, pointer makes pointer movement to the precalculated position (step S706) through CPU 20 not when the picture end.Then, judge whether to supress definite key 25 by CPU 20.When not pressing when confirming key 25, get back to step S703, repeat above-mentioned action.

Supress when confirming key 25 when in step S707, being judged as by CPU 20, then, CPU20 will represent that the Imagery Data Recording of (with hands coincide) image that pointer is indicated in dismantled and assembled memory 17 (step S708), returns from subprogram.

In this execution mode, like Figure 13 and shown in Figure 14, the picture of display part 18 shows 3 two field pictures with the mode of horizontal row, also can lack than 3 frames yet can how than 3 frames.And, can not be horizontal row, but show a plurality of images on the whole at picture in length and breadth.In this case, show such image in picture central authorities here, that is: this image is to be presented at the image on the display part 18 at the moment tr3 that shifts to an earlier date response time τ m (Fig. 2) than the moment tr2 that detects the 2nd release-push 21b closed (releasing operation).Perhaps, show such image in picture central authorities, that is: this image is to shift to an earlier date response time τ m ' captured image of the moment (Figure 11) than the moment tr2 that detects the 2nd release-push 21b closed (releasing operation).And, be that the possibility of image of best scene is the highest owing to be presented at the image of this picture central authorities, thereby pointer also initially is presented at picture central authorities.

In this execution mode; Division display has such multiple image on display part 18, that is: this multiple image is included in than detects the closed moment of the 2nd release-push 21b and has shifted to an earlier date (Figure 11) captured image of the response time τ m (Fig. 2) that is stored in the nonvolatile memory 19 or response time τ m '.Then, when the cameraman selects desired image from the image of this division display, represent that the view data of the image of this selection is recorded in the dismantled and assembled memory 17.Therefore, energy efficiency well and is reliably selected best scene and it is recorded in the recording medium.

In this execution mode; Has releasing operation portion; This releasing operation portion comprises the 1st release-push 21a that moves through the 1st operation and is used to take the 2nd release-push 21b that the laggard action of above-mentioned the 1st operation of continuing of desired image is done, and wherein the 1st operation is used for starting the shooting action; The image selection 21d of portion clips above-mentioned releasing operation portion and disposes a plurality of options buttons, on display part 18, on indicating by the position of a plurality of images of division display respectively, shows the pointer that moves according to the operation of a plurality of options buttons.Then, when supressing when confirming key 25, expression is stored in the dismantled and assembled memory 17 by the view data that is presented at the indicated image of pointer on the display part 18.Therefore, operability is good, can successfully make a video recording → operation of image selection → image record.

And; In this execution mode; In a plurality of images of division display; In the multiple image data that are stored in the internal memory 12, than detect the closed moment of the 2nd release-push 21b shift to an earlier date response time τ m (Fig. 2) be presented at image on the display part 18, or than detect the closed moment of the 2nd release-push 21b shift to an earlier date response time τ m ' (Figure 10) captured image be presented at picture central authorities, and pointer also initially is presented at picture central authorities.Therefore, the cameraman can select desired image apace and it is recorded in the dismantled and assembled memory 17.This is because the image that is presented at picture central authorities is that the possibility of image of best scene is the highest.
