Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for displaying date information at a relatively low cost and with low power consumption operation, and more particularly to a camera for freely arranging a date display section and a film imprinting section. It is about.

[0002]

2. Description of the Related Art Conventionally, a camera having a function of imprinting date information such as shooting date and time on a film is configured to externally display the imprinted information so that an operator can check it in advance, and the same as the display. The information of the content will be optically recorded on the film surface after photographing. In such a camera, the date information display unit, the imprinting unit, and the display content selection / change unit are arranged relatively close to each other and are controlled substantially independently of the operation of the camera (No. 1
Prior art).

On the other hand, nowadays, a camera is realized in which a display section for date information and photographing information and an imprinting section are arranged apart from each other (second prior art). That is, FIG.
As shown in FIG. 3, the camera includes an information display unit 105 that displays shooting information such as shutter speed and aperture value and the date information, and an information display control unit 103 that controls display contents of the information display unit 105. A date setting input section 101 for setting the date information, an imprinting section 106 for recording the date information on a film, and the imprinting section 1
It is composed of an imprinting control unit 104 for controlling the image pickup device 06 and a photographing operation start signal input unit 102 for instructing the start of the photographing operation.

In such a configuration, the information display section 10
5, it is possible to intensively display the date, shooting information, etc. to the photographer. Therefore, it is easy to understand the information,
There is also an advantage that the degree of freedom in the arrangement of the information display unit 105 and the imprinting unit 106 is large.

[0005]

However, in the above-mentioned first prior art, it is necessary to separately provide an imprint display section dedicated to date information and an external display section dedicated to photographing information. The external display unit and the imprinting display unit are both LCDs.
In the case of (1), the LCD control lines of the segment and the common are wired at separate positions in order to display the information on both the external display and the imprinting section, which increases the substrate area.

Further, the display is normally driven by the LCD at 1/3 to 1/4 duty in order to drive with low power consumption, but the projection is driven at 1/2 duty in order to secure the light quantity. In this case, independent control of the common terminal is required, and twice as many common terminals are required. Therefore,
An IC for driving such a special LCD is expensive, and the camera itself is also expensive.

In view of such a point, a camera is also realized in which selection / setting of imprint data, imprint operation and imprint display control are performed by a date display section, and external display of the date is performed by a camera operation control section. However, with the camera,
It has been necessary to communicate the changed information from the date display section to the camera operation control section in order to change the display content when the date selection / setting change occurs. Therefore, when the setting is changed at power-off, the camera operation control unit needs to be operated. Therefore, the camera operation control unit needs to continue operating or at least be activated at the time of selecting / changing the date. Therefore, the control becomes complicated and the power consumption becomes large.

On the other hand, in the second prior art, when the date information is set by the date setting input unit 101, the information display unit 10 is indirectly provided via the imprint information control unit 104.
5, the imprinting information control unit 10
This cannot be set when the power source of No. 4 is off, and as a result, the imprint information control unit 104 needs to be always turned on, resulting in large power consumption. This was the same when setting the date information while checking it on the information display unit 105. Also, the imprinting information control unit 1
04 and the information display control unit 10 require complicated wiring for communicating date information, and it is difficult to downsize the camera itself.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to display photographic information in a concentrated manner and to have a degree of freedom in arrangement of a film imprinting section and an external display section. It is to provide a camera that realizes low power consumption and low cost.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline of a camera of the present invention will be described with reference to FIGS. 1 (a) and 1 (b). The configuration shown in FIG. 1A relates to a camera that displays date information such as shooting date and time and records the date information on a film.

That is, the camera includes an information display section 5 for displaying photographing information such as shutter speed and aperture value and the date information, and an information display control section 3 for controlling display contents of the information display section 5. , Controlling the date setting input section 1 for setting the date information and inputting the date information to the information display control section 3, the imprinting section 6 for recording the date information on a film, and the imprinting section 6 And a photographing operation start signal input unit 2 for instructing the start of the photographing operation. When the start of the photographing operation is instructed, the imprint information control unit 4 is provided. Becomes the operating state.

According to this structure, first, since the date information can be imprinted on the film after the photographing operation start signal is input, the imprinting information control unit 4 and the imprinting information are imprinted until the photographing operation is started. The power of the unit 6 can be turned off, and power saving control (control with low power consumption) becomes possible. Further, secondly, since the photographing information and the date information are displayed on the single information display unit 5, the display unit dedicated to the date information is not necessary, and the display unit 5 can be constructed at a relatively low cost.

Thirdly, since the date information is directly input to the information display section 5 by the date setting input section 1 so as to be settable, the power of the imprint information control section 4 and the imprint section 6 is turned off. It can be set in the state where it is set. As a result, power saving control (control with low power consumption) becomes possible. Fourthly, even when the powers of the imprinting information control unit 4 and the imprinting unit 6 are turned off, the date setting can be performed while checking the display unit 5, so power saving control (control with low power consumption)
Becomes possible.

Fifth, since the date information is transmitted only from the information display control unit 3 to the imprint information control unit 4, the wiring between them can be simplified, and the information display unit 5 and the imprint information can be imprinted. The degree of freedom of arrangement with the portion 6 is increased.

When the camera operation start section 7 switches to the operating state, the shooting information or date information is displayed on the display segment 5a, and when the camera is switched to the non-operating state, the shooting information is displayed. The display is prohibited.

According to such a configuration, first, since the photographing information and the date information are displayed on the shared display segment 5a, the display means can be downsized and the power saving display can be performed. Secondly, when the camera is in a non-operating state, the display of the shooting information is prohibited, so that it is easy to set the date information (time adjustment or mode change) without switching the display. In addition to the above, as a third, similar to FIG.
Since the date information can be imprinted on the film after the photographing operation start signal is input, the imprinting information control unit 4 and the imprinting unit 6 can be turned off until the photographing operation is started. Control with power consumption) is possible.

The configuration shown in FIG. 1 (c) relates to a camera for displaying date information such as shooting date and time and recording the date information on a film.

The information display control section and the input processing section of the input processing section 9 receive inputs from the photographing information setting input section 8 and the date setting input section 1 when the camera operation starting section 7 is in the operating state. The processing based on the input from the photographing information setting means section 8 is prohibited when the camera operation starting section 7 is in the non-operation state.

According to such a configuration, first, the photographing information and the date information are displayed on the common display segment 5a, so that the display means can be downsized and the power saving display can be performed. Secondly, when the camera is in a non-operating state, the display of the photographing information is prohibited, so that it is easy to set the date information, that is, adjust the time and change the mode without switching the display.

The outline of the camera of the present invention has been described above. Next, an embodiment in which the configuration and operation of FIGS. 1A and 1B are further embodied will be described. First, FIG. 2 is a diagram showing a configuration of a camera according to the first embodiment.

Here, FIG. 3 shows the external display section of the camera and the state of the input switch for selecting and changing the display contents arranged in the periphery of the display section. In the same figure, each display of shutter time, aperture and date is displayed on a 7-segment display unit, shutter time display is performed on a 4-digit segment 41, and aperture display is performed on a 2-digit segment 42. The date display is performed using a 6-digit segment that also serves as the segments 41 and 42. Date setting / selection is made with three switches: “MODE”, “SET”, and “ADJUS”
This is performed by setting the switch unit 54 composed of "T". The specific contents of each display will be described later.

The exposure mode is selected by the exposure mode selection switches MODE1 (50) and MODE2 (51). The exposure mode selection display 43 is MODE1 (50)
By pressing, the exposure modes P (program) → S (shutter priority auto) → A (aperture priority auto) → M (manual) are sequentially selected in the arrow direction.

Further, the exposure mode selection display 44 by the image selection pre-programmed according to the photographing scene.

Each time the ASH 53 is pressed, the contents of the display 48 are selected in the arrow direction in the order of auto → red eye reduction → forced → flash inhibition. The exposure correction and the film frame number display are displayed on the display unit 45 consisting of two-digit segments, and the correction amount is selected by the switch 55.

Further, a display section 46 for warning the remaining battery level is arranged above the exposure compensation display. Further, on the right side of the flash mode display 48, a display section 49 for performing function selection display is arranged. Here, it is displayed whether or not each function of the self-timer, remote controller, macro, power focus (electrically manual lens drive), and spot metering is selected.

Next, FIG. 4 shows how the display section is mounted on the camera 61 and will be described. FIG. 4A is a view as seen from the rear lid side. Each setting switch is provided around the LCD 62, the aperture value shift switch 64 is provided on the left side, the film sensitivity confirmation window 66 is provided on the right side, and the shutter speed shift switch 65 is provided above it.
And the shutter release 63.

FIG. 4B shows the case where the rear lid is opened and seen from the inside. A film pressure plate 67 is arranged at the position shown in the figure, and a projection LCD 68 for projecting light through a pressure plate window is provided behind it. It is arranged.

Here, FIG. 5 is a diagram showing a display form of the shutter, aperture and date. As shown in the figure, in this embodiment, the display contents of the display mode and the operation mode are changed as follows by the display mode selection flag DMODE.

That is, DMODE = 0: display off. DMODE = 1: (month / day / year) display. DMODE = 2: (day / month / year) display. DMODE = 3: (year / month / day). Display-DMODE = 4: (day / hour / minute) display-DMODE = 5: Shutter second display-DMODE = 6: Aperture value display-DMODE = 7: (Shutter second / aperture value) display .

Hereinafter, with reference to the flowchart of FIG.
The date displaying and imprinting operations by the DCPU 12 will be described in detail. When the operation starts, the DCPU 12 first turns on the main clock (step S1), and the RAM
Read out the contents (step S2) and display the shooting information on the LCD
It is displayed on B21 (step S3). Then, the timer TD for displaying this photographing display for the first predetermined time is initialized (step S4), and the timer TD sets the first predetermined time T.
It is detected whether D0 has been reached (step S5).

Then, the timer TD is set to the first predetermined time TD.
If it has not reached 0, it is confirmed whether or not the shooting operation start switch 1R is turned on during that time (step S7). If the 1R is not turned on, after counting up the timer TD (step S7). Then, the process returns to step S5.

On the other hand, the timer TD sets the first predetermined time TD0.
If it is determined that the shooting information can be confirmed and the shooting has not been started, then it is determined whether or not the flag DTFLG indicating that the date setting / change has occurred in the process described below is “1”. Check from RAM contents (step S
6). Here, when DTFLG = 1, the photographing display is switched to the date display (step S9). After this processing,
Or, when DTFLG is other than 1, or 1R in step S7
When is turned on, a second predetermined time timer TMD for display is initialized (step S10).

Subsequently, the DCPU 12 checks whether there is a switch interrupt (step S11), and if there is no interrupt, checks whether there is a print request (step S12). If there is a request for imprinting, the imprinting process is performed (step S15). The switch interruption is the display setting switches MODE1 (50) and MODE2.
(51), DRIVE52, FLASH53, DATE
Switches (MODE, SET, ADJUST) 54, aperture shift switch 64, shutter shift switch 65,
It is generated by the correction shift switches 55, 1R and other switch inputs such as spot metering (not shown).

When there is an interrupt in step S11, the TMD is initialized again (step S13), and a subroutine "input setting" process described later is executed (step S).
14). Then, the DCPU 12 checks whether the flag DTFLG is "1" (step S16), and DTFLG
When = 1, the date is displayed (step S17).

After all the above processing, that is, step S1
When there is no print request in step 1, or step S17
Is displayed, or when DTFLG is not "1", or after the imprinting process in step S15, the DCPU 12 sets the PW
Check whether RSW is turned off (step S1)
8). Here, when the power is not turned off, the DCPU
12 checks whether the display is a date display (step S
20). If the date is displayed in step S20, the process returns to step S11.

On the other hand, when the date is not displayed in step S20, the DCPU 12 checks whether or not the timer TMD has reached the second predetermined time TMD0 (step S20).
21) If the predetermined time has not been reached, the TMD is counted up (step S23) and the above step S
Return to 11.

When the TMD has reached the predetermined time, it is confirmed whether DTFLG is "1" (step S
22), and when DTFLG = 1, the date is displayed (step S24). After this, or in step S22 above, DT
When FLG is not "1", the DCPU 12 checks whether the power supply flag DPWR of the imprinting unit is on (step S25). If it is not turned on, the process returns to step S11. If it is turned on, the DPWR is turned off in step S26, and the step S11 is turned on.
Return to.

On the other hand, in step S18, the PWRS
When W is off, the DCPU 12 uses the main clock MA
INCLK is turned off (step S19), the time counting operation is started, and the operation is ended.

Next, referring to the flowchart in FIG. 7, the subroutine "input setting" executed in step S14 is executed.
Will be described. First, the DCPU 12 confirms whether the switch interrupt is a date setting related interrupt (step S31). Here, in the case of a date interrupt, the date interrupt generation flag DTFLG is set to "1" (step S34).

The interrupt related to the date setting is MOD.
It is an interrupt generated by each switch input of E, SET, and ADJUST. Also, some cameras have specifications that do not have a date and imprint function. In such a camera, since the date setting switch is not present, DTFLG = 1 is not set. Therefore, DTF
LG can also be used to determine if a camera is dated or not.

After step S34, the DCPU 12 causes the LED control flag LEDF for illuminating the display section in the finder.
Is turned on (step S35), and when the LEDF is off, the camera is not in the shooting state and the display in the viewfinder is off, and subsequently the date setting process described later is performed (step S36). ).

On the other hand, when the LEDF is on, the LEDF is once turned off (step S37). This is because the connection of the aperture display segment between the viewfinder display and the camera external display is common during shutter speed, so the display in the viewfinder becomes the date display while the date is set. This is a process for turning off the illumination to make the display temporarily unrecognizable in order to make people feel uncomfortable.

After that, the DCPU 12 performs the date setting process (step S38), and after the process, turns on the LEDF again (step S39). On the other hand, when the interrupt is not related to the date setting in the step S31, the DCPU 12 checks whether or not it is 1R (step S32), and when it is 1R, the photographing display process is performed (step S33). Therefore, the shutter / diaphragm / date display unit displays the shutter speed and the aperture value. When it is not 1R in step S32,
The DCPU 12 checks whether it is an operation mode setting interrupt (step S40).

This operation mode interrupt is an interrupt generated by each of the MODE1, MODE2, DRIVE, FLASH, correction shift, aperture shift and shutter time shift switch inputs. If the operation mode interrupt is detected in step S40, the DCPU 12
Performs operation mode display processing (step S41). In this processing, operation mode selection processing and display change are performed.

On the other hand, if it is not the operation mode interrupt in step S40, the DCPU 12 performs a function selection process (step S42). This function selection process is selected by inputting spot metering or the like, and changes the contents of the display 59 or the like in FIG. When the above process is finished, the input setting process is finished,
Return to the main routine.

Next, the operation of the subroutine "imprinting process" executed in step S15 will be described with reference to the flowchart of FIG. First, the DCPU 12 reads the DMODE flag indicating the imprint display contents (step S51), and confirms whether DMODE is "0" (step S52). Here, when DMODE = 0, the imprinting display is turned off, that is, the imprinting process is unnecessary, and thus this process is terminated. On the other hand, when DMODE is other than 0, DCP
U12 reads the flag DRV indicating the drive mode (step S53).

Subsequently, the DCPU 12 is in the DRV = C mode and DP which is the power control flag of the imprinting unit.
It is confirmed whether or not the WR is turned on (step S54), and when this condition is not satisfied, the DPWR is turned on and the copying unit is powered on (step S55). Then, the DMODE and DS are displayed so that the display is the same as the date display content.
Each setting of ET and DADJUST is transmitted to the imprinting display control unit (steps S56, 57, 58).

When step S58 or S54 is true,
It is checked whether or not the exposure operation is completed (step S5
9) If not finished, wait until it is finished. Then, when the exposure operation ends, the data imprinting light source DL
The AMP is turned on (step S60). Next, the imprinting timer TL is initialized (step S61) and waits until the required time T is reached (steps S62 and S63). DCP
U12 will DLAMP when this TL reaches a predetermined time T.
Is turned off (step S64).

Subsequently, the DCPU 12 checks whether the drive mode DRV is the C mode (step S65),
In the C mode, the process is ended. In the other modes, the power of the imprinting unit is turned off and the process ends (step S66). In the C mode, since the next imprinting operation is likely to occur in a relatively short time, the power of the imprinting section is kept on and the processing speed is prioritized.

Next, the operation of the subroutine "date setting" executed in step S36 of FIG. 7 will be described with reference to the flowchart of FIG. First, the DCPU 12 uses the timer T
S is initialized (step S71), and the date is displayed on the display unit (step S72). Then, it is confirmed whether or not the DMODE flag which is turned on by the input of the date display setting mode switch MODE is turned on (step S73).
Here, when the DMODE is turned on, the DCPU 12 sets the mode by the DMODE (step S75),
The date display is selected to the set date (step S7)
6).

On the other hand, when the DMODE is not turned on in step S73, it is confirmed whether the DSET flag for selecting the display setting section to be turned on by the input of the switch SET is turned on (step S74). And DSET
If is not turned on, the process ends. On the other hand, when DSET is on, the DCPU 12
The change portion is selected by SET (step S77), and the selected display is blinked (step S78).

Subsequently, the DCPU 12 checks whether or not the DADJUST flag which is turned on by the input of the switch ADJUST for changing the content of the selected change section is turned on (step S79). Here, when DADJUST is turned on, the setting content is checked, when the selected content is "year" (step S80), the setting of "year" is changed (step S81), and when it is "month" ( Step S82), "Month"
Setting is changed (step S83), and when it is "day" (step S84), the setting of "day" is changed (step S8).
5) When it is "hour" (step S86), the setting of "hour" is changed (step S87), and when it is "minute" (step S88), the setting of "minute" is changed (step S8).
9).

When the "minute" is not set in the above step S88, or after the above-mentioned respective setting change processing, or after the processing of step S86, or step S89 is DAJUS.
In each case where the T flag is not turned on, the process proceeds to step S90, and it is checked whether DSET is turned on or DMODE is turned on. Here, when DSET or DMODE is turned on, the setting is confirmed (step S91), and the process ends.

When neither DSET nor DMODE is turned on, it is checked whether or not the setting permission timer TS has reached the predetermined time TS0 (step S92). If not, the timer is counted up (step S94), and step S94 is performed. Return to S90. When the timer ST has reached the predetermined time, the setting is stopped (step S93), and the processing is ended in this manner.

As described above, in the camera of the present invention, since the control other than the film imprinting information display control is performed by the photographing information display control section, the information intensive external display for displaying the photographing information and the date display and the film copying. There is an advantage that wiring can be efficiently performed by a configuration separated from the recessed portion, and that even when the power is turned off, only the photographing information control portion can respond to the date setting change.
