The power down mode of present embodiment is described now.
When by power supply/when photograph mode switch key 8 switches to photograph mode, power connection, microcomputer 19 each square frames of control, control is carried out the setting of the various functions of video cameras such as focal length setting to the state or the lens 13 of recording mediums 16 such as the read/write adjustment of recording medium 16 or capacity inspection.Whether detect simultaneously, can be to recording medium 16 records.Then, if be can recording status, then become the record holding state of power connection, the user waits for operation dynamic image photography key 7 or still image photographing key 9.But also can in view finder 24 or liquid crystal indicator 25, show record with the image that is taken.Then, when the user presses dynamic image photography key 7 or still image photographing key 9, opening entry.If be can not recording status, then becoming power connection can not recording status.Here, also can show with the image that is taken on view finder 24 or LCD 25 can not record.In addition, under power connection record holding state, because with photography with write down relevant circuit block and moving, the time of recording start is short.
When under power connection record holding state, when pressing province's telegraph key 11, video camera is transferred to power down mode, lights LED12.In addition, when under power connection can not recording status, pressing province's telegraph key 11, can in view finder 24 or LCD 25, show the information that can not write down.Like this, owing to forbid switching to power down mode can not be to recording medium 16 record the time, LED12 does not light, and can prevent therefore that the user from thinking by mistake can record.
In addition, under power down mode, take out under the situation of recording medium 16, by drive unit 17, detect the microcomputer 19 that has taken out recording medium 16 and remove power down mode, becoming power connection can not recording status.In addition, under power down mode, operating power/photograph mode switch key 8, under the situation of change photograph mode, removing power down mode, judgement could be behind record under the photograph mode after the switching, in the time of can writing down, become power connection record holding state, the user waits for operation dynamic image photography key 7 or still image photographing key 9.
When under power down mode, when removing the power down mode in lens 13, CCD14, video camera DSP15, drive unit 17, audio frequency 20, graphic circuit 23, view finder 24, LCD 25, the outside output 26 etc., shortened the circuit block action of the time of the record holding state that arrives power connection, other circuit blocks stop action, are transferred to power down mode.For example, view finder 24 or LCD 25 become power down mode by cancellation display frame; But move to the position of Fast starting lens 13 in advance at lens 13 after, stop the action of drive circuit piece.In addition, each circuit blocks such as CCD14 or video camera DSP15, drive unit 17, audio frequency 20, graphic circuit 23, outside output 26 also become the power saving holding state.Generally, because aperture 30 stops (zero load) by action, complete atresia (closing fully), therefore, microcomputer 19 is controlled, make under power down mode, by aperture control part 31, aperture 30 complete atresia.In addition, microcomputer 19 is stored in the controlling value of the preceding aperture 30 of power down mode.
In addition, under the situation of offhand power down mode, operate condition is become consume electric power low and start fast state.For example, be to consume under the few situation of electric power for this circuit block at the state that is not writing down the holding state reproduced image, also few under playback mode, can suppress to consume electric power.
Secondly, utilize Fig. 3, Fig. 4 illustrates when the video camera of present embodiment is transferred to power down mode and the flow process of the processing in the power down mode.Fig. 3 is the flow chart of the video camera of present embodiment to the power down mode transfer processing, and Fig. 4 is the flow chart of the processing in the power down mode of the video camera of expression present embodiment.
Present embodiment by pressing province's telegraph key 11, can make video camera be transferred to power down mode.When pressing province's telegraph key 11 once more, remove power down mode, but become the power connection record holding state of opening entry immediately, can power saving, and the time when shortening recording start.Below expression at length.
In step S1, when by power supply/photograph mode switch key 8, when switching to the operation of photograph mode, power connection.In step S2, carry out the starting of video camera.Here Biao Shi photograph mode is meant dynamic image pattern or the rest image pattern that is used to write down dynamic image or rest image.In the step S2 of the start up process of video camera, be controlled at the state or the lens 13 of recording mediums 16 such as the read/write adjustment of recording medium 16 (hereinafter referred to as medium) or capacity inspection, when carrying out preparing to handle, carry out the detection that whether can on recording medium 16, write down for the photography of the various functions of the setting video camera of setting focal length etc.Whether among the step S3, judge the processing by carrying out in step S2, be the state that can write down under the photograph mode of selecting on the recording medium 16.But if be recording status, but then be transferred to the power connection recording status (hereinafter referred to as the record holding state) of step S4, wait for that the user operates dynamic image photography key 7 or still image photographing key 9.When the user presses dynamic image photography key 7 or still image photographing key 9, opening entry.At this moment, because from record holding state opening entry, can opening entry in the short time.
Here, but what is called recording status and record holding state are meant medium 16 are inserted in these video cameras that and medium 16 has residual amount, the state of image that can chronophotography.In addition, the photograph mode that selection can be write down on the medium 16 that inserts means the capacity abundance of battery 4 etc., can utilize the state of dynamic image photography key 7 and still image photographing key 9 document images.
When in step S3, judging in step S2, the capacity that does not have the image of records photographing on medium 16, do not insert medium 16, when the off-capacity of battery 4 etc. is not the recordable state of this video camera, can not carry out the photography of step S5 though move to, the state of the power connection of video camera body (hereinafter referred to as can not recording status).
Under the record holding state of step S4, when in step S6, pressing province's telegraph key 11, move to the power down mode of step S7.At this moment, the expression video camera is that the LED12 of power down mode lights.Because under the power down mode, the display frame of view finder 24 or LCD 25 disappears, can suppress misunderstanding by lighting LED12 with power-off state.
In addition, when step S5 can not recording status under, when in step S17, pressing province's telegraph key 11, in step S18, on view finder 24 or LCD 25, show the information that can not write down, what be back to step S5 can not recording status.Like this, but only under the recording status of step S4, it is just effective to economize telegraph key 11, during the releasing power down mode, but must be recording status.In addition, when step S5 can not recording status under, when pressing province's telegraph key 11, by showing the reason that can not move to power down mode, the state that can not write down to the user prompt video camera can prevent user's misidentification.
Secondly, utilize Fig. 4, expression moves to the flow process of the processing behind the power down mode.Under power down mode, can in step S8, S9, S10, S11, S12, carry out the inspection of camera status at any time.
After in step S7, moving to power down mode, in step S8, judge when pressing province's telegraph key 11 once more, remove power down mode, get back to the record holding state of step S4.At this moment, do not carry out the condition judgement of medium 16 or the camera function setting carried out etc. in common start up process, make video camera move to the record holding state, therefore opening entry immediately prevents to miss the chance of optimum lens.
That is: when being back to the record holding state, cancellation the view finder 24 of display frame or the display frame of LCD 25 become ON (connection), carry out the focus adjustment of lens 13 etc., make each circuit block such as CCD14, video camera DSP15, drive unit 17, audio frequency 20, graphic circuit 23, outside output 26 become the ON state.
Like this, by display image quickly on view finder 24 or LCD 25, the cameraman can make the picture angle adjust to the body direction that is taken apace.Specifically, after removing power down mode, microcomputer 19 by aperture control part 31, is open into first state with aperture 30 immediately.At first, the suitable transit dose (going into light quantity) that under this first state, is adjusted to and photographs.
First state can have no particular limits according to the photography state decision of imagination.For example, if make aperture 30 become (the opening entirely) state of opening fully, then relatively make the open a little dark place of aperture effective especially.In addition, if be complete atresia (contract fully) state, then relatively the bright place of locking is effective especially a little making aperture.If the state in centre position in the place of various brightness, can obtain average effect.
In addition, first state, the controlling value to aperture 30 before the power down mode of use storage in microcomputer 19 also can.In this case, by making aperture 30 effective when not changing in the photography place at the state of its controlling value or near the state its controlling value (for example, open fully, complete atresia, centre position etc.).Controlling value is that grade etc. is also passable at numerical value without limits.In addition, be stored in the microcomputer 19 also passablely, it is also passable that other memory is set, and is generically and collectively referred to as exposure state storage portion.Position when staying position with aperture 30 and moving to battery saving mode is also passable, but owing to worry to produce imaging apparatus etc. and damage, preferably store controlling value, according to it, opens aperture 30.
On the other hand, when common starting (disconnecting energized), open aperture 30 at leisure, adjust the transit dose that is suitable for photographing from second state littler than first state from power supply.Like this, by starting to power connection, can switch the control of aperture 30 from common starting and battery saving mode.
In addition, be not limited to the control of aperture 30.Utilize the speed time time for exposure of (each (for example 1/60 second)) of the shutter of imaging apparatus (CCD14) by prolongation, can increase exposure.In addition, by improving the magnification ratio of enlarging function (AGC: automatic gain is controlled), also can increase exposure based on video camera DSP15.In these controls, utilize microcomputer 19 or the figure control part or the driver that do not illustrate, can switch exposure in the starting that begins from common starting and battery saving mode.At this moment, same with the control of aperture 30, during battery saving mode, can begin to adjust from predefined set-point (for example maximum, minimum, centre etc.).Value when being transferred to battery saving mode is stored in the exposure state storage portion, adjusts controlled quentity controlled variable according to this value and also can.
Use these methods or with the control combination of aperture 30, by starting to power connection, switch light exposure control from common starting and battery saving mode, when when battery saving mode starts, the cameraman adjusts picture angle easily apace.Particularly, if postpone the speed time of shutter, the amount of opening aperture 30 is little, also can obtain given exposure.Even increased magnification also has same effect.In addition, when aperture 30 is followed the action of machinery, the reaction when regulating exposure is than the reaction Chi Shi of imaging apparatus or AGC etc., uses these or its combination effectively.
When Eject key 6 is pressed in judgement in step S9, remove power down mode, dielectric cap (not illustrating among the figure) is opened, and takes out medium 16.Because be not have the state of medium 16 or the state that dielectric cap is opened, so video camera gets back to step S5, and becoming can not recording status.
When in step S10, judging power down mode through the regular hour, remove the power down mode of video camera, in step S16, disconnect the power supply of video camera body.The surface sees that province's electric power state disconnects near power supply, and is different with common power supply disconnection, though than the power saving of common power connection state, but consume electric power.By deenergization automatically, shorten holding time of battery in order to suppress a little, can remove power down mode within a certain period of time, power supply disconnects.This certain hour by the user set also can, it is also passable to preestablish for 30 regular times that grade.For this reason, during next energized,, become common start up process owing to be not from the power down mode starting.
When judging that in step S11 battery 4 or AC adapter (not illustrating among the figure) when extracting, remove the power down mode of video camera, in step S16, deenergization.For this reason, when next energized,, become common start up process owing to be not from the power down mode starting.
Utilize when in step S12, judging power supply/when photograph mode switch key 8 changed dumps or photograph mode, in step S14, judgement was set at power supply/photograph mode switch key 8 which state of video camera.When in step S14, when judging the photograph mode change, photograph mode before becoming power down mode is under the situation of dynamic image photograph mode, change to the still image photographing pattern, perhaps the photograph mode before power down mode is under the situation of rest image image pickup mode, changes to dynamic image photograph mode etc.When photograph mode change (No), remove power down mode, in step S15, according to photograph mode after changing, the starting video camera is got back to step S4, becomes the record holding state.In addition, being (Yes) under the disconnection, in step S16, disconnect the power supply of video camera with power settings.
In step S15, under the situation of change photograph mode, but must confirm under photograph mode after changing whether be recording status, the state of video camera and medium 16 when checking start up process.In addition, but can guarantee from dynamic image photography pattern to the mode altering of still image photographing pattern etc., with dynamic image photography-record comparison usually to being transferred under the recording status situation of the change of the little still image photographing-logging mode of recording capacity etc., can save this start up process.
More than, utilizing Fig. 3, Fig. 4 represents that video camera is transferred to the flow process of power down mode, the handling process under the power down mode of video camera in the power down mode.Like this, by set can be immediately to the power down mode of the transfer of record holding state, can power saving, and can shorten time of recording start.In addition, because under the situation that can not write down, not power down mode, can prevent therefore that the user from thinking by mistake can record.
Secondly, utilize Fig. 5 that demonstration example in step S18 is described.Picture example when Fig. 5 shows for the information of the video camera of expression present embodiment.
Show the information 28 that can not write down on the picture 27 of LCD, photograph mode or date etc., other showed 29.Owing to do not insert medium 16, the information 26 of the situation that can not write down can show " not inserting medium " as expression.In addition, cause, then show this reason if the reason that can not write down is an other reasons.
In addition, the kind of the key of the video camera of Fig. 1 of expression and battery etc. or configuration are an example among the embodiment 1, and content displayed or configuration are without limits.In addition, Fig. 3, the transfer shown in Fig. 4 to power down mode, in power down mode, the example that the processing in the power saving is only handled, contents processing is without limits.Certainly, increase and decrease processing project also can, to the processing of the power saving of camera head without limits.
