Abstract

The invention provides a photographic device, which enables a photographic device that shifts from the normal action state to the power-saving holding state to resort to the normal action state easily and inhibits the waste of power caused by unexpected restoration to the normal action state. A digital camera (100) capable of underwater shooting is structured by a water detection sensor (116) and a pressure sensor (112), which can judge whether the camera (100) is in water. The camera (100) has a knock operation permission mode, in which the action of the camera (100) varies based on the result of the vibration operation of the user detected by a vibration detection part (400). The structure can detect the vibration operation so as to enable the camera to resort to normal action state from holding state. Therefore, when the camera (100) is not in water, even if the vibration operation is detected, the camera is not resorted to normal action state; when the camera is in water, the camera is resorted to normal action state when vibration operation is detected.

Camera

Technical field

The present invention relates to camera, being specifically related to have can be by providing the camera of the camera main body being swung, knocked the user interface that such vibration operates.

Background technology

Generally, the operation of mode switch of camera etc. is to be operated and carry out being located at console switch on the camera by the user.Yet, along with the progress of camera miniaturization, above-mentioned sometimes console switch to set the space not enough.In order to address this problem, following camera is disclosed in patent documentation 1: detect the vibration impose on camera, can be according to should detected vibration exporting command signal identical when having operated console switch.

And, in the compact electronic devices such as camera that move as power supply with battery, the electronic installation that adopts following structure is arranged: this electronic installation is a purpose to suppress battery consumption, when detecting when not carrying out operation within a certain period of time, transfers to the power saving operate condition.This power saving operate condition is called as standby (standby) state (standby mode (standby mode)), dormancy (hibernation) state (park mode (hibernation mode)) etc.The electronic installation that is in the power saving operate condition is by keeping the function of the operated situation of detecting operation parts, and stops other functions and reduce power consumption.And, constitute and can return to common operate condition when functional unit is operated immediately detecting.By such formation, even the user forgets to close power supply after electronic installation uses, also can detect and not carry out operation within a certain period of time and transfer to the power saving operate condition automatically, can suppress the consumption in vain of battery.

[patent documentation 1] TOHKEMY 2000-125184 communique

As the opportunity that returns to common operate condition from above-mentioned power saving operate condition, except the operated situation of detecting operation parts, it also is effective detecting the vibration that imposes on electronic installation.That is, make the electronic installation that is in the power saving operate condition return to common operate condition as long as the user can apply to vibrate by the functional unit of operating electronic devices or to electronic installation, then operability just improves.

In addition, as the electronic installation that can in water, use, have and do not use waterproof case (housing) and monomer can carry out in the water camera with water-proof function of photography action.Yet the camera with water-proof function is also considered on land the use of (in the air) and has been designed dial (dial), button (button), slide bar functional units such as (slide liver).In water, the operability of camera is descended owing to the user has on face shield in the water (mask) and gloves.And, owing to buoyancy, hydraulic pressure or flow action descend the operability of camera in cameraman (user).Therefore, in the camera that can carry out photography action in the water, operate by constituting to be applied to vibrate to camera by the user, the operability of camera improves.

And, be accommodated under the situation of carrying out photography action in the water in the waterproof case at the camera that will not have water-proof function, in order to operate in the functional unit that camera is equipped with from the outside of waterproof case, need link, the action that this link is used for being located at the functional unit on the waterproof case is delivered to the functional unit that is accommodated in the camera in the waterproof case.At this moment, in order to operate in whole functional units that camera is equipped with, be necessary a large amount of functional units and link are located in the waterproof case from the outside of waterproof case.Like this, it is complicated that the structure of waterproof case becomes, and it is big that waterproof case self also becomes.And, owing to have link to get involved, thereby operability descends sometimes.To this, operate by constituting to apply to vibrate to camera by the user, can reduce the quantity of camera operation necessary operations parts, it is simple that the structure of waterproof case also becomes.

But, return to from the power saving operate condition under the situation of common operate condition, have problems sometimes detecting the vibration that imposes on electronic installation.For example suppose that the user forgets to close power supply when electronic installation being accommodated in case or the bag etc.If under this state, carry electronic installation, then sometimes electronic installation is applied vibration.When the electronic installation in the power saving pattern detects this vibration, return to common pattern.When electronic installation being applied intermittently vibration, can not stably keep power down mode, can not suppress the consumption in vain of battery.

118A, 118B, resistance value rises, and resistance value testing circuit 352 outputs to system controller 300 with the High signal.Like this, constitute water test section 352 by water detecting sensor 116 and resistance value testing circuit 352.By this water test section, CPU 303 can judge that digital camera 100 is whether in water.

In addition,, can replace water detecting sensor, and use the water detecting sensor of using optical sensor with

electrode

118A, 118B as above-mentioned water detecting sensor 116.As the structure of optical sensor, can adopt the structure that has the illuminating part that sends infrared light etc. and receive the light accepting part of the light that penetrates from illuminating part.And what bases such as refractive index existed between this illuminating part, light accepting part is that air or water change, and can constitute light quantity to the light that incides light accepting part and change and detect, and can judge that digital camera 100 is in water or in air.

Pressure sensor 112 constitutes to have: be formed with diaphragm 110, amplifying circuit 354 and constant current circuit 356 as the bridge resistor 358 of distortion meter (gauge).As shown in Figure 3, bridge resistor 358 forms the closed circuit (bridge circuit) that utilizes four points of connection to connect four resistance, connect amplifying circuit 354 on one group of tie point in mutual opposed two groups of tie points, connecting constant current circuit 356 on another group tie point.Follow diaphragm 110 to be under pressure and be out of shape, the resistance value that constitutes four resistance of bridge resistor 358 changes.Thus, the balance collapse in the bridge circuit produces potential difference between a pair of tie point that is connected with amplifying circuit.354 pairs of these potential differences of amplifying circuit are amplified and are outputed to A/D converter 316.Like this, constitute piezometry portion by the diaphragm 110 that constitutes pressure sensor 112 (bridge resistor 358), amplifying circuit 354 and constant current circuit 356.By this piezometry portion, CPU 303 can judge that digital camera 100 is whether in water.

The example that above logarithmic code camera 100 has water detecting sensor 116 and pressure sensor 112 is described.Because digital camera 100 has water detecting sensor 116 and pressure sensor 112, thereby when photography in the rain, can be that photography is distinguished in land photography or the water to this photography.And, even be positioned at very shallow depth of water place at digital camera 100, be difficult to judge digital camera 100 whether under the situation in water according to the pressure detecting result of pressure sensor 112, also can judge that easily digital camera 100 is whether in water according to the testing result of water detecting sensor 116.Digital camera 100 can have only any one transducer in above-mentioned water detecting sensor 116 and the pressure sensor 112.

And, in the present embodiment, suppose that digital camera 100 is not use waterproof case etc. and the digital camera that can monomer carries out photographing in the water is illustrated, yet also can be can be accommodated in to carry out the digital camera of photographing in the water in the waterproof case.In this case, can constitute, make the projection that is located in the waterproof case, in water, use thereby CPU 303 can detect digital camera 100 by the switch (detect whether shell is installed) that is pressed on the digital camera 100.

Vibration detecting part 400 constitutes to have: previously described acceleration transducer 114 and the handling part of the signal of exporting from acceleration transducer 114 being handled and outputed to system controller 300.

Fig. 4 is the block diagram of the schematic configuration of explanation vibration detecting part 400.Vibration detecting part 400 has: electric power control part 402, acceleration transducer 114, X-axis acceleration handling part 410, Y-axis acceleration handling part 420 and Z axle acceleration handling part 430.

Electric power control part 402 will offer each inscape in the vibration detecting part 400 from the electric power that power circuit 322 (Fig. 3) provides.Export control signals via input and output portion 310 to this electric power control part 402 from CPU 303.And CPU 303 constitutes and can whether electric power be offered each inscape in the vibration detecting part 400 by this control signal control electric power control part 402.Thus, (stopping) being forbidden in the action permission and the action of CPU 303 may command vibration detecting parts 400.

Acceleration transducer 114 has the X-axis acceleration transducer 404 of the acceleration (vibration) that can detect X-direction illustrated in figures 1 and 2, the Y-axis acceleration transducer 406 of acceleration (vibration) that can detect Y direction and the Z axle acceleration sensor 408 that can detect the acceleration (vibration) of Z-direction.

Output signal from these X-axis acceleration transducers 404, Y-axis acceleration transducer 406 and Z axle acceleration sensor 408 is imported into corresponding X-axis acceleration handling part 410, Y-axis acceleration handling part 420 and Z axle acceleration handling part 430.Because the internal structure of these X-axis acceleration handling parts 410, Y-axis acceleration handling part 420 and Z axle acceleration handling part 430 is basic identical, thereby the following internal structure that X-axis acceleration handling part 410 only is described.

X-axis acceleration handling part 410 has amplifier 412 and waveform shaping portion 418.Waveform shaping portion 418 has comparator 414 and filter 416.Amplifier 412 will be amplified to from the signal of X-axis acceleration transducer 404 outputs and can be input to A/D converter 316 by the level of 316 processing of the A/D comparator in the system controller 300.The output signal of amplifier 412 also is imported into the filter 416 that constitutes waveform shaping portion, and the unwanted signal component is input to the non-counter-rotating input part of comparator 414 by filter 416 removals.CPU 303 outputs to D/A converter 318 with the numerical data corresponding with the reference voltage (Vref) of the counter-rotating input part that should be input to comparator 414.It is the analog signal of Vref and the counter-rotating input part that is input to comparator 414 that D/A converter 318 becomes voltage with this digital data conversion.Be output to input and output portion 310 and interruption controls portion 312 from the signal of comparator 414 outputs.

According to said structure, amplify by amplifier 412 from the acceleration signal of X-axis acceleration transducer 404 outputs, by filter 416 filtering, being converted to by comparator 414 afterwards can be at the binary signal (high signal/low signal) of input and output portion 310 in the

system controller

300 and 312 inputs of interruption controls portion.CPU 303 can knock operation by what the user carried out according to the state-detection of this binary signal.At this moment, CPU 303 changes the value of the numerical data that outputs to D/A converter 318, thereby the value of the reference voltage (Vref) of the counter-rotating input part that is input to comparator 414 is changed, and can change the detection sensitivity of acceleration thus arbitrarily.

And, converting numerical data from the acceleration signal of amplifier 412 outputs to by A/D converter 316, these data are handled by CPU 303, thereby can detect user's the operation of knocking.This structure can detect the complicated operations pattern (user knocks operation for the first time by force and and then carries out knocking operation a little less than the secondary) that illustrates later.That is, CPU 303 can detect user's logarithmic code camera 100 add shake the operation in case with the regulation the vibrative situation of vibration mode.At this moment, the waveform shaping function that has of waveform shaping portion 418 can use the software of being carried out by CPU 303 to realize.

From the output signal of Y-axis acceleration handling part 420 and Z axle acceleration handling part 430 also with the same A/D converter 316, D/A converter 318, input and output portion 310 and the interruption controls portion 312 of being imported into of output signal from X-axis acceleration handling part 410.

More than, vibration detecting part 400 is constituted the example that can detect X, Y, Z three axial vibrations be described, yet vibration detecting part 400 also can constitute and only can detect 1 direction of principal axis or 2 axial vibrations.And, can also constitute the rotation (shaking) that can detect around X, Y, the Z arbitrary axis in each.

Such digital camera that constitutes 100 as described above has common operate condition and holding state, and this holding state is to carry out standby with the consumption electric power that lacks than common operate condition to move the operate condition of the operation of waiting for the user.Under holding state, CPU 303 sends control signal to power circuit 322, only provides electric power to required minimal functional block.CPU 303 self also constitutes and can transfer to so-called sleep mode (Sleep mode), to reach the consumption electric power lower than common operate condition.

, under being state at the power connection of digital camera 100, the transfer of holding state carries out from common operate condition from user's last operation digital camera 100 during when the state continuance of function digit camera 100 does not surpass such stipulated time of for example 30 seconds, 1 minute (user) through the stipulated time.

And, when CPU 303 has exported interrupt signal, carrying out from interrupting control part 312 to the recovery of common operate condition from holding state.Undertaken from interrupting the action of control part 312 by console switch 332 being operated to CPU 303 output interrupt signals by the user.

Digital camera 100 constitutes not to be accommodated in the waterproof case etc. and can carry out photographing in the water.As mentioned above, because digital camera 100 has water detecting sensor 116 and pressure sensor 112, thereby can judge that digital camera 100 is whether in water.Digital camera 100 also constitutes, and can be waited by user operation menu switch 122 and set the photograph mode that close-up photography pattern etc. is suitable for photographing in the water in snap pattern in the water (snap mode), the water.When in water, using, also transfer to holding state from common operate condition as mentioned above sometimes.

For also making the digital camera 100 that is in holding state, user in water returns to common operate condition, as long as console switch 332 is operated.Yet when photographing in water, the user has gloves on and face shield, perhaps bears the resistance of hydraulic pressure and water, is not easy sometimes console switch 332 is operated.In order also easily to operate in this case, digital camera 100 constitutes and can return to common operate condition from holding state by user's the operation (adding the operation of shaking) of knocking.

But, the power supply that the user forgets to close digital camera 100 can take place usually just put it into the situation of carrying in case or the bag.In this case, because digital camera 100 is transferred to holding state, thereby can suppress power consumption in vain.Yet, if merely be made as by the knocking operation and also can return to common operate condition from holding state of user, following problem might take place.That is, when owing to follow carrying in the vibration that produces on the digital camera 100 and from interrupting control part 312 when CPU 303 output interrupt signals return to common operate condition, have digital camera 100 possibility of power consumption in vain in the carrying.

Therefore, in digital camera 100,, and can suppress above-mentioned power consumption in vain, carry out the control that in following the 1st to the 3rd execution mode, illustrates for the action of in water, carrying out easily recovering to common operate condition.In addition, in the 1st to the 3rd execution mode of following explanation, the internal structure of digital camera 100 is all identical, is the content that before illustrates referring to figs. 1 through Fig. 4.And, by the control process difference of CPU 303 execution.

-Di 1 execution mode-

Fig. 5 A and Fig. 5 B are the flow chart of explanation by the summary treatment progress of CPU 303 execution in the digital camera 100 of the 1st execution mode of the present invention.By by the treatment progress shown in CPU 303 execution graph 5A and Fig. 5 B, the control that briefly shows below the formation.

(1) under not detecting the situation of digital camera 100 in water or digital camera 100 be not set under the situation of the photograph mode that is suitable for photographing in the water, even digital camera 100 is set to the permission pattern of knocking, CPU 303 also makes the vibration detection action in the vibration detecting part 400 stop when transferring to holding state.Thus, though when holding state, have by knock vibration that operation produces or to impose on digital camera 100 by knocking the similar vibration of vibration that operation produces, do not carry out recovery to common operate condition yet.

(2) be detected under the situation in water or be set under the situation of the photograph mode that is suitable for photographing in the water at digital camera 100, if be switched to the operation permission pattern of knocking, then CPU 303 sets the vibration detection action of proceeding in the vibration detecting part 400 for when transferring to holding state.Thus, be detected under the situation in water or be set under the situation of the photograph mode that is suitable for photographing in the water at digital camera 100, by the digital camera 100 that is in holding state being knocked operation, can return to common operate condition by the user.

(3) under digital camera 100 is detected situation in water, perhaps under the situation that is set to the photograph mode that is suitable for photographing in the water, if be switched to the attendant exclusion pattern of knocking, then CPU 303 makes the vibration detection action in the vibration detecting part 400 stop when transferring to holding state.Thus, under digital camera 100 is detected situation in water, perhaps under the situation that is set to the photograph mode that is suitable for photographing in the water, if be switched to the attendant exclusion pattern of knocking, even then to the digital camera 100 that is in holding state apply by knock vibration that operation produces or to by knocking the similar vibration of vibration that operation produces, can not return to common operate condition yet.

Below, the treatment progress of being carried out by CPU 303 is described with reference to the flow chart of Fig. 5 A and Fig. 5 B.Treatment progress shown in Fig. 5 A and Fig. 5 B is to have connected at the mains switch 106 of having been operated digital camera 100 by the user under the situation of power supply or from interrupting control part 312 to begin to move when CPU 303 has exported interrupt signal.

In S500, the initial setting when CPU 303 carries out systems starting in the digital camera 100 corresponding to the kind of starting process.That is,, make memory, input and output portion and the initialized processing of other functional blocks corresponding to the kind of starting process.Here, starting process has two kinds.A kind of is operating power switch 106, the process that system is started down from the state that stops fully.Another kind of process is to make the process of system from the holding state starting.

In S502, CPU 303 carries out the setting of timer counter 314.CPU 303 is according to the timing signal from timer counter 314 outputs, carries out from the input of the signal of pressure sensor 112 outputs and the processing of shifting to holding state from common operate condition.

In S504, whether CPU 303 judgements have been operated is knocked operation permission switch 124.Knock operation when allowing switch 124 when CPU in S504 303 is judged to be to have operated, enter S506, judge that the operator scheme of current setting is knocked operation permission pattern or knocked the attendant exclusion pattern.When the operator scheme that is judged to be current setting in S506 is to knock under the situation of attendant exclusion pattern, in the S508 as the branch destination, CPU 303 carries out operator scheme is switched to the setting of knocking operation permission pattern.

CPU 303 sends control signal to the electric power control part 402 of vibration detecting part 400 and starts vibration detecting part 400 in S510, via D/A converter 318 reference voltage V ref is outputed to comparator 414 backs to S534.When reference voltage V ref being set big, can reduce knocking operational sensitivity.Otherwise, when reference voltage V ref is set hour, can improve knocking operational sensitivity.That is, under the situation of setting reference voltage V ref greatly, when the user does not carry out byer force when knocking operation, CPU 303 can not discern this and knocks operation.Otherwise under the situation of setting reference voltage V ref for a short time, even the user carries out the slight operation of knocking, CPU 303 also can identify this and knock operation.Owing to also be subjected to the influence of the gain of the characteristic of acceleration transducer 114 and amplifier 412 to knocking operational sensitivity, thereby expectation is will to be recorded in the flash memory 344 based on the Control Parameter of the calibration result of vibration detecting part 400 in the manufacture process of digital camera 100.

The operator scheme that is judged to be current setting in S506 is that CPU 303 carries out operator scheme is switched to the setting of knocking the attendant exclusion pattern among the destination S512 of branch that knocks under the situation of operating the permission pattern.In ensuing S514, CPU 303 sends the action that control signal stops vibration detecting part 400 to the electric power control part 402 of vibration detecting part 400, enters S534.

Judgement in S504 is among the destination S520 of branch under the situation of negating, and CPU 303 judges whether carried out the operation of menu switch 122, when this judgement when being sure, enters S522.In S522, the current operator scheme of setting in digital camera 100 of CPU 303 judgements is knocked operation permission pattern or is knocked the attendant exclusion pattern.The operator scheme that is judged to be current setting in S522 is among the destination S524 of branch that knocks under the situation of attendant exclusion pattern, CPU 303 operates console switch 332 corresponding to the user, carries out the selection of the pattern of digital camera 100, the setting of photography conditions, the processing such as demonstration of reproduced image.Afterwards, CPU 303 enters the processing of S534.

The operator scheme that is judged to be current setting in S522 is among the destination S526 of branch that knocks under the situation of operating the permission pattern, CPU 303 is according to the operation of knocking from the input user of vibration detecting part 400 outputs, knocks operation and carries out the selection of the pattern of digital camera 100, the setting of photography conditions, the processing such as demonstration of reproduced image according to detected.CPU 303 enters the processing of S534 afterwards.

Judgement in S520 is under the situation of negating, and promptly is being judged to be under the situation of not operating menu switch 122, and CPU 303 enters S530.CPU 303 judges whether operated shutter release switch 108 in S530, when this judgement when being sure, enter S532.CPU 303 carries out a series of actions relevant with photography in S532.That is, CPU 303 carries out the warming-up exercises of photographing such as the focal adjustments action, photometry action of phtographic lenses 102, does not make the on-off action of illustrated shutter afterwards.Afterwards, CPU 303 sends control signal to image processing part 304 and image compression decompression portion 305.Receive this control signal, 304 pairs of view data from 336 outputs of imaging apparatus interface circuit of image processing part are carried out image processing, 305 pairs of view data from image processing part 304 outputs of image compression decompression portion are compressed processing, are recorded in the processing in the storage card 340.The CPU 303 that has finished the processing of S532 enters S534.

Judgement in S530 is among the destination S540 of branch under the situation of negating, and CPU 303 judges whether passed through the stipulated time and console switch 332 all is not operated.When the judgement among the S540 when being sure, CPU 303 enters S542, and the interruption of following the user to operate allows to handle.That is, 303 couples of CPU interrupt control part 312 and set, so that export interrupt signals from interrupting control part 312 to CPU 303 when having operated console switch 332 in holding state.

In ensuing S544, the operator scheme of the current setting of CPU 303 judgements is knocked operation permission pattern or is knocked the attendant exclusion pattern.The operator scheme that is judged to be current setting in S544 is to knock under the situation of attendant exclusion pattern, and CPU 303 is set at holding state with system controller 300, and CPU 303 self also enters sleep pattern.

The operator scheme that is judged to be current setting in S544 is to knock under the situation of operation permission pattern, and CPU 303 is branched off into S546.In S546, CPU 303 judges that digital camera 100 is whether in water or be set to photograph mode in the water.Judgement in S546 is under the sure situation, promptly is being judged to be digital camera 100 in water or be set under photograph mode in the water or both sides' the situation, and CPU 303 enters S548, allows the interrupt action of vibration detecting part 400.Promptly, 303 couples of CPU interrupt control part 312 and set, so that vibration detecting part 400 is maintained operate condition, detect vibration and exported to interruption controls portion 312 from comparator 414 under the situation of signal to CPU 303 output interrupt signals at vibration detecting part 400.By setting like this, can when digital camera 100 be in holding state, knock operation and return to common operate condition along with the user by CPU 303.

Judgement in S546 is among the destination S550 of branch under the situation of negating, CPU 303 to the electric power control part 402 output control signals of vibration detecting part 400 so that the action of vibration detecting part 400 stop.

CPU 303 finishes the processing of S548 or S550, and system controller 300 is set at holding state, and CPU 303 self also enters sleep pattern.By the processing of the S550 that carries out by CPU 303, when being in holding state, digital camera 100 do not accept to knock operation.Thus, when carrying is in the digital camera 100 of holding state,, can not return to common operate condition even logarithmic code camera 100 applies and similarly vibrated by the vibration of knocking the operation generation yet.

Regularly whether the judgement in S540 is among the destination S560 of branch under the situation of negating, and CPU 303 judges whether operated mains switch 106, when this judgement when being sure, enters S562, on the other hand, to judge when this, gets back to S504.In S562, CPU 303 is used for the setting action of halt system, finishes a series of processing.

The processing of the S534 that carries out after the processing of S510, S514, S524, S526 or S532 is to be used for timer counter 314 is carried out initialized processing, this timer counter 314 is when common operate condition is transferred to holding state, and the time of the state of user's inoperation digital camera 100 is carried out timing.By the initialization of this timer counter 314, for example set 30 seconds, 1 minute such time and begin countdown (or increasing progressively counting).That is,, thereby in through the S534 after these steps, make timer counter 314 initialization because S510, S514, S524, S526, S532 have carried out the step of and then carrying out after the Any user operation.The CPU 303 of processing of S534 of being through with gets back to S504, repeats above-mentioned processing.

The processing of S090 shown in the key diagram 5A, S092 and S094.When digital camera 100 (system controller 300) when being in holding state,, send interrupt signal to CPU 303 from interrupting control part 312 along with having carried out user's operation or having knocked operation.In addition, only vibration detecting part 400 maintains under the situation of operate condition when transferring to holding state, sends interrupt signal by knocking operation.The CPU 303 that starts by receiving this interrupt signal carries out the processing of S090, S092 and S094.

In S090, the operator scheme of the current setting of CPU 303 judgements is knocked operation permission pattern or is knocked the attendant exclusion pattern.In the operator scheme that is judged to be current setting is to knock under the situation of operation permission pattern, and CPU 303 enters S092, judges that digital camera 100 is whether in water or be set to photograph mode in the water.Judgement in S092 is under the situation of negating, promptly neither in water, be not set under the situation of photograph mode in the water being judged to be digital camera 100 yet, CPU303 enters S094, send control signal to the electric power control part 402 of vibration detecting part 400 and start vibration detecting part 400, to comparator 414 output reference voltage Vref, enter S500 via D/A converter 318.

The operator scheme that is judged to be current setting in S090 is to knock under the situation of attendant exclusion pattern, has perhaps carried out in S092 under the situation of sure judgement, and CPU 303 does nothing and enters S500.

In the 1st execution mode, digital camera 100 has to knock to be operated the permission pattern and knocks the attendant exclusion pattern as the operator scheme that can set.And, be set under the state that knocks operation permission pattern, when transferring to holding state, the action of vibration detecting part 400 stops.Therefore, even logarithmic code camera 100 applies and operates the similar vibration of vibration that produces by knocking in holding state, can not return to common operate condition yet, thereby can suppress power consumption in vain from holding state.

On the other hand, be set to the operation permission pattern of knocking at digital camera 100, and be judged to be digital camera 100 in water or be set under the situation of photograph mode in the water, vibration detecting part 400 maintains operate condition when transferring to holding state, allow the interrupt action of vibration detecting part 400, thereby make the digital camera 100 that is in holding state return to common operate condition by knocking operation under the situation that can in water, photograph, can improve the operability of digital camera 100.

In addition, the reason of carrying out the vibration detecting part start up process in S094 is because when digital camera 100 is being set to when transferring to holding state under the state that knocks operation permission pattern, stop the action of vibration detecting part in S550.That is, this is because when when holding state returns to common operate condition, be necessary to make vibration detecting part 400 startings so that the operation permission pattern of knocking that sets before holding state shifts is effective.

-Di 2 execution modes-

Fig. 6 A and Fig. 6 B are the flow chart of explanation by the summary treatment progress of CPU 303 execution in the digital camera 100 of the 2nd execution mode of the present invention.By by the treatment progress shown in CPU 303 execution graph 6A and Fig. 6 B, the control that briefly shows below the formation.

(1) is not detected under the situation in water or is not set under the situation of the photograph mode that is suitable for photographing in the water at digital camera 100, when digital camera 100 is being set to when transferring to holding state under the state that knocks operation permission pattern, CPU 303 proceeds the vibration detection action in the vibration detecting part 400.CPU 303 is the high value of setting than under common operate condition (Vref2) of vibration detection rank (Vref1) at this moment with the vibration detection grade setting.Thus,, also be difficult to carry out recovery, power consumption in vain such as when being suppressed at the carrying of digital camera 100 to common operate condition even logarithmic code camera 100 applies and by knocking the similar vibration of vibration that operation produces when holding state.

(2) be detected under the situation in water or be set under the situation of the photograph mode that is suitable for photographing in the water at digital camera 100, when digital camera 100 is being set to when transferring to holding state under the state that knocks operation permission pattern, CPU 303 proceeds the vibration detection action in the vibration detecting part 400.CPU 303 this moment is the low value (Vref3) of vibration detection rank (Vref2) during than above-mentioned holding state with the vibration detection grade setting.Thus, be detected under the situation in water or be set under the situation of the photograph mode that is suitable for photographing in the water at digital camera 100, when the user knocks operation to the digital camera 100 that is in holding state, can return to common operate condition with comparalive ease.

(3) be switched under the situation of knocking the attendant exclusion pattern at digital camera 100, when CPU 303 transfers to holding state, no matter whether digital camera 100 is detected in water or whether is set to the photograph mode that is suitable for photographing in the water, do not carry out the vibration detection action in the vibration detecting part 400.Thus, be switched under the situation of knocking the attendant exclusion pattern at digital camera 100, even to the digital camera 100 that is in holding state apply by knock vibration that operation produces or to by knocking the similar vibration of vibration that operation produces, do not carry out recovery to common operate condition yet.

Below, the treatment progress of being carried out by CPU 303 is described with reference to the flow chart of Fig. 6 A and Fig. 6 B.In the treatment progress shown in Fig. 6 A and Fig. 6 B, treatment progress mark and the identical step number of step number that marks in Fig. 5 A and Fig. 5 B to identical with the treatment progress shown in Fig. 5 A and Fig. 5 B omit its explanation.And, be that the center describes with difference with the 1st execution mode.

In Fig. 6 A, treatment progress (S610, S612) that begins to carry out when take place interrupting and the operator scheme that is judged to be current setting in S504 are that the treatment progress (S620 to S624) that knocks under the situation of attendant exclusion pattern is different with the 1st execution mode.And in Fig. 6 B, the operator scheme that is judged to be current setting in S544 is that the treatment progress (S600 to S606) that knocks under the situation of operating the permission pattern is different with the 1st execution mode.

Describe with reference to Fig. 6 A.Operated when being judged to be in S504 that to knock the operator scheme that operation allows switch 124 and be judged to be current setting in S506 be when knocking the attendant exclusion pattern, CPU 303 is set at the operation permission pattern of knocking with the pattern of digital camera 100 in S620.In ensuing S622, CPU 303 sets vibration detection rank in the vibration detecting part 400 like that by following explanation.That is, the CPU 303 reference voltage V ref that will be input to the counter-rotating input part of comparator 414 is set at reference voltage, the 1st reference voltage of setting (being referred to as " Vref1 " for simplicity) when knocking operation permission pattern under operate condition usually.Next CPU 303 enters S624, sends control signal with starting vibration detecting part 400 to the electric power control part 402 of vibration detecting part 400.

Next, describe, in S540, be judged to be not detect the operation of digital camera 100 and begun to transfer to the interruption that the CPU 303 of the processing of standby action follows the user to operate in S542 and allow through the stipulated time with reference to Fig. 6 B.That is, 303 couples of CPU interrupt control part 312 and set, and export interrupt signals from interrupting control part 312 to CPU 303 when having operated console switch 332 with box lunch in holding state.Then, in ensuing S544, the operator scheme of the current setting of CPU 303 judgements is knocked operation permission pattern or is knocked the attendant exclusion pattern.More than, S540, S542 are identical with the 1st execution mode with contents processing among the S544.

Then, the operator scheme that is judged to be like that current setting as described below in S544 is that the processing of knocking under the situation of operation permission pattern is different with the 1st execution mode.In S600, CPU 303 judges that digital camera 100 is whether in water or be set to photograph mode in the water.

Judgement in S600 is under the situation of negating, and promptly neither also is not set in water under the situation of photograph mode in the water being judged to be digital camera 100, and CPU 303 enters S606.In S606, the vibration detection rank in the CPU 303 change vibration detecting parts 400.Specifically, the reference voltage V ref that is input to the counter-rotating input part of comparator 414 is set for high the 2nd reference voltage of when knocking operation permission pattern, setting than under common operate condition (being referred to as " Vref2 " for simplicity) of the 1st reference voltage V ref1.

On the other hand, judgement in S600 is under the sure situation, promptly be judged to be digital camera 100 in water or be set under photograph mode in the water or both sides' the situation, CPU 303 enters S602, the vibration detection rank in the change vibration detecting part 400.Specifically, the reference voltage V ref that is input to the counter-rotating input part of comparator 414 is set for 3rd reference voltage (for simplicity be referred to as " Vref3 ") lower than above-mentioned the 2nd reference voltage V ref2.

The CPU 303 of processing of S602 or S606 of being through with enters S604, allows the interrupt action of vibration detecting part 400.Promptly, 303 couples of CPU interrupt control part 312 and set, so that vibration detecting part 400 is maintained operate condition, detect vibration and exported to interruption controls portion 312 from comparator 414 under the situation of signal to CPU 303 output interrupt signals at vibration detecting part 400.Then, CPU 303 is set at holding state with system controller 300, and CPU 303 self also enters sleep pattern.

The processing of S610 and S612 is described referring again to Fig. 6 A.When digital camera 100 (system controller 300) when being in holding state,, send interrupt signal to CPU 303 from interrupting control part 312 along with having carried out user's operation or having knocked operation.The CPU 303 that starts by receiving this interrupt signal carries out the processing of S610 and S612.

In S610, the operator scheme of the current setting of CPU 303 judgements is knocked operation permission pattern or is knocked the attendant exclusion pattern.In the operator scheme that is judged to be current setting is to knock under the situation of operation permission pattern, and CPU 303 enters S612.In S612, CPU 303 enters S500 via the comparator 414 output reference voltage Vref1 of D/A converter 318 to vibration detecting part 400.

When digital camera 100 is being set to when transferring to holding state under the state that knocks operation permission pattern, the reference voltage that the processing by above-mentioned S600, S602 and S606 will output to comparator 414 changes to Vref2 or Vref3.For making this reference voltage V ref, promptly to return to original rank be Vref1 to the vibration detection rank in the vibration detecting part 400, carries out above-mentioned processing in S612.

Result by CPU 303 carries out above-mentioned processing sets Vref1 as the vibration detection rank when being set to when the digital camera 100 that knocks operation permission pattern is in common operate condition.And, when being set to the digital camera 100 that knocks operation permission pattern when transferring to holding state, be judged to be digital camera 100 in water or be set to photograph mode in the water, or under both sides' the situation, setting Vref3 as the vibration detection rank.And, when being set to the digital camera 100 that knocks operation permission pattern when transferring to holding state, neither in water, be not set under the situation of photograph mode in the water being judged to be digital camera 100 yet, set Vref2 as the vibration detection rank.

The magnitude relationship of above-mentioned Vref1, Vref2, Vref3 is, Vref2 is greater than Vref1, and Vref3 is less than Vref2.That is, when being set to the digital camera 100 that knocks operation permission pattern when transferring to holding state, neither also be not set in water under the situation of photograph mode in the water at this digital camera 100, the vibration detection sensitivity of vibration detecting part 400 is low.Therefore, just do not recover if do not apply the operation of knocking strong when being in common operate condition less than common operate condition.Therefore, forget to close power supply and carry in the situation of digital camera 100, even logarithmic code camera 100 has applied and by knocking the similar vibration of vibration that operation produces, also recover less than common operate condition when this vibration rank is no more than Vref2 the user.Thus, can suppress because the recovery of not expecting to common operate condition is moved and power consumption in vain.

On the other hand, when under being set to the state that knocks operation permission pattern, transferring to holding state, be judged to be digital camera 100 in water or be set to photograph mode in the water, or under both sides' the situation, be the Vref3 littler than Vref2 with the vibration detection grade setting.Thus, the vibration detection sensitivity of vibration detecting part 400 improves.Therefore, comparing in the water that is difficult to operate with ground (in the air), can easily make digital camera 100 return to common operate condition from holding state, the operability of digital camera 100 improves.About this Vref3, be set at the value littler as described above, yet also can be set at the value higher than Vref1 than Vref2, also can be set at the following value of Vref1.And, also can constitute and can freely set this Vref1, Vref2 and Vref3 according to user's hobby or type of service.

-Di 3 execution modes-

Fig. 7 A, Fig. 7 B and Fig. 7 C are the flow chart of explanation by the summary treatment progress of CPU 303 execution in the digital camera 100 of the 3rd execution mode of the present invention.By by the treatment progress shown in CPU 303 execution graph 7A to Fig. 7 C, the control that briefly shows below the formation.

(1) is being set to when transferring to holding state under the state that knocks operation permission pattern when digital camera 100, always allowing the interrupt action of vibration detecting part 400.

(2) under the situation of the interrupt action that vibration detecting part has taken place, CPU 303 judges digital camera 100 whether in water or be set to the photograph mode that is suitable for photographing in the water, under this judgement is sure situation, returns to common operate condition.

(3) under the situation of the interrupt action that vibration detecting part 400 has taken place, CPU 303 judges that digital camera 100 is whether in water or be set to the photograph mode that is suitable for photographing in the water, in this judgement is under the situation of negative (digital camera 100 in air and be not set to photograph mode in the water), CPU 303 measures the output signal from vibration detecting part 400 at the appointed time, and vibrational waveform (knocking the operation format of operation) is analyzed.Then, this vibrational waveform with by the knocking under the not corresponding situation of vibrational waveform that operation obtains of regulation, CPU 303 makes digital camera 100 transfer to holding state once more.On the other hand, under the vibrational waveform situation corresponding with the vibrational waveform essence of operating acquisition by knocking of regulation, CPU 303 makes digital camera 100 return to common operate condition.

Below, the treatment progress of being carried out by CPU 303 is described with reference to the flow chart of Fig. 7 A to Fig. 7 C.In the treatment progress shown in Fig. 7 A to Fig. 7 C,, omit its explanation to the treatment progress identical mark and the identical step number of step number at Fig. 5 A and Fig. 5 B mark with the treatment progress shown in Fig. 5 A and Fig. 5 B.Then, be that the center describes with difference with the 1st execution mode.

In Fig. 7 A, the processing when interrupt taking place is because the situation of paper moves on to Fig. 7 C, except appended represent to be branched off into the connector D in processing path of S500 from the processing shown in Fig. 7 C, do not have difference with shown in Fig. 5 A.In Fig. 7 B, when common operate condition is transferred to holding state, the operator scheme that is judged to be current setting in S544 is that the processing of the S720 when knocking operation permission pattern is different with the 1st execution mode shown in Fig. 5 B.Processing when the interruption shown in Fig. 7 C takes place is different on the whole with the processing of the 1st execution mode shown in Fig. 5 A.

Describe with reference to Fig. 7 B.In S540, be judged to be not detect the operation of digital camera 100 and begun to transfer to the interruption that the CPU 303 of the processing of standby action follows the user to operate in S542 and allow through the stipulated time.That is, 303 couples of CPU interrupt control part 312 and set, so that export interrupt signals from interrupting control part 312 to CPU 303 when having operated console switch 332 in holding state.Then, in ensuing S544, the operator scheme of the current setting of CPU 303 judgements is knocked operation permission pattern or is knocked the attendant exclusion pattern.More than, S540, S542 are identical with the 1st execution mode with contents processing among the S544.

Then, the operator scheme that is judged to be like that current setting as described below in S544 is that the processing of knocking among the S720 that carries out under the situation of operation permission pattern is different with the 1st execution mode.In S720, CPU 303 allows the interrupt action of vibration detecting part 400.Promptly, 303 couples of CPU interrupt control part 312 and set, so that vibration detecting part 400 is maintained operate condition, detect vibration and exported to interruption controls portion 312 from comparator 414 under the situation of signal to CPU 303 output interrupt signals at vibration detecting part 400.Then, CPU 303 is set at holding state with system controller 300, and CPU 303 self also enters sleep pattern.At this moment, the reference voltage that is input to the counter-rotating input part of comparator 414 can be and be in common operate condition when digital camera 100 and be set to the identical voltage of reference voltage when knocking operation permission pattern, also can be different voltage.

The processing of S700 to S710 is described with reference to Fig. 7 C.When digital camera 100 (system controller 300) when being in holding state,, send interrupt signal to CPU 303 from interrupting control part 312 along with having carried out user's operation or having knocked operation.The CPU303 that starts by receiving this interrupt signal begins to carry out the processing from S700.

In S700, CPU 303 judges whether the arbitrary switch that constitutes console switch 332 is connected.Judgement in S700 is certainly, and when the operation that promptly is judged to be the console switch 332 that the user carries out was the reason of interrupting taking place, CPU 303 entered S500 (Fig. 7 A).On the other hand, the judgement in S700 whether regularly, CPU 303 enters S702.Here the determination processing result among the S700 is remarked additionally.Interrupt, the judgement among the S700 is negative, promptly console switch 332 access failures mean, digital camera 100 is transferred to holding state being set under the state that knocks operation permission pattern, vibration detecting part 400 detects vibration and interrupts.But, can not clearly judge by vibration detecting part 440 detected vibrations be that operation causes by knocking of user, or cause by simple vibration.For making this judgement clear and definite, carry out the processing of the S702 to S708 of following explanation.

In S702, CPU 303 judges that digital camera 100 is whether in water or be set to photograph mode in the water.Judgement in S702 is that CPU 303 enters the processing of the S500 of Fig. 7 A under the sure situation.That is, be judged to be digital camera 100 in water or be set under photograph mode in the water or these both sides' the situation, CPU 303 enters S500, returns to the processing of common operate condition.This be because, the user has gloves on etc. in water, and bears the resistance of hydraulic pressure and water, carry out sometimes with carry out on the ground identical to knock operation be difficult, thereby can arrive common operate condition by the simpler operation recovery that knocks.Much less there is not latent tool diving, carry aqualung diving exactly, diving time also is about one hour at the most, as mentioned above, promptly enables easily to return to common operate condition, the influence of power consumption is also little in vain.

Judgement in S702 is under the situation of negating, and promptly under the situation that digital camera 100 uses on the ground, CPU 303 enters S704, for example imports (supervision) signal from vibration detecting part 400 outputs in 2 seconds, 5 seconds such time at the appointed time.In S706, the vibrational waveform that 303 pairs of inputs by S704 of CPU (supervision) obtain is analyzed.

In S708, the analysis result that CPU 303 judges among the S706, promptly it is with whether essence is corresponding by the predetermined vibrational waveform that knocks the operation acquisition.When the judgement among the S708 when being sure, CPU303 enters the processing of S500, carries out the recovery action to common operate condition.On the other hand, judgement in S708 is negative, be that analysis result among the S706 is it and knock under the not corresponding situation of vibrational waveform that operation obtains by predetermined, because having by vibration detecting part 400 detected vibrations is not the possibility of operating the vibration that causes by knocking, thereby gets back to holding state once more.

As mentioned above, in the 3rd execution mode, when digital camera 100 is in common operate condition S526 accept knock operation (by knocking the vibration mode that operation produces) with when digital camera 100 is in holding state S708 acceptance to knock operation (by knocking the vibration mode of operating generation) different.

Here, with reference to Fig. 8 above-mentioned vibration mode is described.Fig. 8 (a) example is illustrated in logarithmic code camera 100 and has carried out knocking under the operation situation of (adding the operation of shaking) from acceleration transducer 114 outputs, amplified, carried out waveform shaping and the waveform of the signal exported by filter 416 by amplifier 412.Fig. 8 (b) example illustrates the signal waveform from comparator 414 outputs when the waveform signal shown in Fig. 8 (a) is imported into the non-counter-rotating input part of comparator 414.

When logarithmic code camera 100 carried out producing waveform 802 knock operation the time, from comparator 414 to interruption controls

portion

312 and 310 outputs of input and output portion signal by waveform 806 expressions.Be set to the operation permission pattern and being under the situation of common operate condition of knocking at digital camera 100, along with from the signal of comparator 414 inputs by waveform 806 expressions, CPU 303 accepts user's the operation of knocking.

On the other hand, S700 to S702, the S704 in handling through the interruption of having done above explanation with reference to Fig. 7 C, S706 are in the processing of S708, and CPU 303 is in S704, at preset time t _RefDuring this time, import Fig. 8 (b) as the signal shown in the waveform 808 from comparator 414.Then, when in the processing that when comparator 414 has been exported three signal C2, C3, C4, returns to common operate condition during this time tref.Promptly in order to start the digital camera 100 that is in holding state, the user is necessary at the appointed time in (tref) to knock camera body continuous three times.On the other hand, in S702, be judged to be digital camera in water or be set under photograph mode in the water or these both sides' the situation, though among input Fig. 8 (b) as the signal shown in the waveform 806, also return to common operate condition.

More than, to when CPU 303 measures the output of vibration detecting part 400, CPU 303 is described from the example of comparator 414 input binary signals.Yet, the invention is not restricted to this.For example, the signal from filter 416 output can also be input to a plurality of comparators that are set with mutually different reference voltage, come vibrational waveform is analyzed according to combination from the signal of these a plurality of comparators outputs.

Perhaps, can also directly analyze by 303 pairs of waveforms of CPU from the analog signal of vibration detecting part 400 outputs.Carry out knocking the signal of exporting from acceleration transducer 114 under the operation situation of (adding the operation of shaking) at logarithmic code camera 100 and be exaggerated device 412 amplifications, be imported into A/D converter 316.Therefore, CPU 303 can be by analyzing the operation of knocking of detection of complex to the output of A/D converter 316.As an example, the signal shown in the waveform 810 of key diagram 9.This situation represents that the user is t at the appointed time _RefKnock during this time three times, for the second time and for the third time knock intensity (P12, P13) than primary knock intensity (P11) a little less than.When the analog signal that detects shown in the waveform 810, the judgement among the S708 is certainly.That is, when surpassing threshold value V1 by the primary signal that knocks generation, the processing of beginning execution graph 7C, when by for the second time and the signal that knocks generation for the third time during less than threshold value V2 and greater than threshold value V3, the judgement among the S708 is certainly.The advantage that the waveform of analog signal is directly analyzed is because more than the binary signal of exporting by comparator from the amount of information of the output of A/D converter, but thereby detection of complex knock operation.

Illustrate that more than having imagined the user knocks (certain surface of camera body) from specific direction.Yet can also adopt such structure, that is, thereby the user knocks (a plurality of not coplanars of camera body) from a plurality of different directions makes digital camera 100 startings that are in holding state.

The signal that CPU 303 exports at a plurality of acceleration transducers (for example, X-axis acceleration transducer 404 and Y-axis acceleration transducer 406) that S704 input (supervision) has from acceleration transducer 114.And, for example ought detect t at the appointed time _RefDuring this time logarithmic code camera 100 carried out along twice of X-direction, next along Y direction once knock when operation being judged to be certainly among the S708.Like this, can distinguish the vibration that the users such as vibration that knock the vibration that causes of operation and produce when the carrying by the user do not expect with higher precision.

The present invention can be applied to that digital camera and Digital Video and other can land and water use can carrying type device etc.
