Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera, and particularly to a camera that can take pictures by remote control.

[Prior Art] Conventionally, a remote-controlled v! 1 (hereinafter referred to as a remote control) has been proposed.A camera with a remote control is very convenient because the photographer can decide the release timing by himself when taking a picture of himself. Cameras with an auto-zoom function have also been proposed.Cameras with an auto-zoom function are very convenient because the camera automatically determines the appropriate magnification without the need for the photographer to operate the zoom.

Note that the auto zoom mechanism is
1D by χ·1 and automatically adjusts the black spot distance f of the photographing lens to become f−βXD so that the set photographing magnification β can be obtained. For example, when a photo is taken in a horizontal position, the magnification β is selected to be 1/120 for a full-body photo taken while fishing on a boat, and β-1/70 for an upper-body photo.
If it is a face photograph, it will be sent on β-1/30.

Table 1 FIG. 6 is a diagram showing the display contents of the display LCD shown in FIG. 1. When the camera is in normal mode, the 6th
The display shown in Figure (a) is shown, when in auto zoom mode, the display shown in Figure 6 (b) is shown, and when in remote control mode, the display shown in Figure 6 (C) is shown. When the camera is in the self mode, a display as shown in FIG. 6(d) is displayed. The entire display segment necessary for performing such a display is shown in FIG. 6(e).

Referring to FIG. 6(e), the display LCD has an auto zoom mode display segment 151, a film presence/absence confirmation display segment 152, a film counter 153, a film loading confirmation display segment 154, and a self mode display segment 155. , a remote control mode display segment 156.

The camera capable of remote photographing and automatic zoom according to the present invention operates in a normal mode, an auto zoom mode, a self mode, a remote control mode, and an auto zoom-special release mode, as shown in FIG. FIG. 7 shows the relationship between such transitions of each mode. Here, the normal mode is a mode in which self-photography and remote photography are not performed, and is not an auto-zoom mode but an initial mode when the camera is activated. The self mode is a mode for self-photography, a mode for taking a group photo, etc., and is a mode in which exposure is performed after -'M time has elapsed after the release button 11 is pressed.

The auto zoom mode (hereinafter abbreviated as AZ mode) automatically adjusts the focal length of the photographing lens to obtain a photo with the set shooting rate of 4Q for the distance to the subject specified by 5.
This is a mode for adjusting IItf. The AZ n1M division mode is a mode in which the AZ mode is divided by an angle q. The remote control mode is a mode for remote photographing using a remote control.

The transition between the above five modes will be explained with reference to FIG. To change from normal mode to AZ mode when the camera is started, it is sufficient to press the auto zoom mode button 13 shown in FIG. The same applies when returning from AZ mode to normal mode. That is, the normal mode and the AZ mode are repeated each time the auto zoom mode button 13 is pressed once. To change from normal mode to self mode, simply press the photographing mode button 16 shown in FIG. 1. Also, when switching to remote control mode, press the shooting mode button 1 in self mode.
Just add 6 to 1. When the shooting mode button 16 is pressed in remote control mode, the mode returns to normal mode. In other words, each press of the shooting mode button 16 switches to normal mode →
Switches from self mode to remote control mode to normal mode.

In addition, when in selfie mode, the camera automatically returns to normal mode after the selfie shot is finished. A from AZ mode
To switch to the Z-time release mode, the zoom operation lever 14 shown in FIG. 1 can be operated to press the zoom-in switch S4 or the zoom-out switch S. Conversely, to return to AZ mode from AZ-stand release mode, turn on the auto zoom mode switch S by holding down the auto zoom mode button 13 shown in Fig. If so, Ll, A
When switching from the Z-time delay mode to the selfie mode, the selfie switch S12 can be turned on by pressing the photographing mode button 16.

To switch between the AZ mode and the self mode, it is sufficient to turn on the auto zoom mode switch S or the self switch S12, respectively. To switch from remote control mode to AZ mode, it is sufficient to turn on the auto zoom mode switch S.

FIG. 8 is a flowchart of a main routine showing the operation of the camera shown in FIG. A camera with a remote photographing function and an auto zoom mode according to the present embodiment starts its operation by inserting a battery into the camera body and resetting it. Referring to FIG. 8, when the camera is reset, an initialization subroutine (#2) is entered for initializing various parameters, flags, and memory '9 for operating the camera. Next, enter the main routine (#4) and press the main switch S. i11 is determined whether or not there has been a change (#6). When it is determined that the main switch SO has changed, the flow shifts to a main switch check routine (#20) for checking the main switch. When the main switch So does not change and is turned off in #6, it is judged whether the main switch So is on or not (jl+ cut off) (#8)
. If the main switch So is off, the process moves to the main routine (#4). If it is determined that the main switch So is on, it is determined whether the /IP+optical switch S is on or not (#10). If it is determined that the switch is on, the processing flow moves to a photometry switch-on routine (#22). If the metering switch S is not on, whether the auto zoom mode switch SJ is on or not is ↑
It is cut off (#12). If it is determined that the switch is on, the processing flow moves to the zoom mode switch-on routine (#24). Auto zoom mode switch S,
is determined to be off, the shooting mode switch S1
2 is on or not (#14), and if it is judged to be on, the shooting mode switch on routine (#26)
The processing flow moves to , and if it is determined that the zoom-in switch S4 is off, it is determined that the zoom-in switch S4 is on or not. If the zoom-in switch S4 is not on, it is determined whether the zoom-out switch S5 is on or not. If the zoom-in switch S is on or the zoom-out switch S5 is on, the processing flow moves to a zoom switch-on routine (#'2R). If the zoom out switch S5 is off in step #18, step #18
19, it is determined whether the mode is remote control mode or not.

If it is not the remote control mode, the program moves to the main routine (#4). In remote control mode, signal R
The state of the MC is determined. If the signal RMC is "H" upon reception of the remote control signal, the program moves to #23, a remote control determination routine. If it is "L", the processing flow proceeds to the main routine (#4) multiple times.

FIG. 9 is a flowchart showing the contents of the main switch So check routine shown at step #20 in the main routine of FIG. Referring to FIG. 9, in the processing flow, when the main switch So check routine is entered, the main switch S is first checked.

It is determined whether the change was from off to on (#
30). If the change is from off to on, the driving direction of the photographic lens 12 is set to the telephoto direction (#3
2). Next, the stopping position of the photographic lens 12 is at the wide end (fourth
19) at the zoom position shown in the figure.

On the other hand, if i11 is disconnected in step #30 because the change in the main switch So is from on to off, then the photographic lens 1
2 is necessary, the drive direction is set to the wide direction (#38), and the stop position of the photographic lens is set to the retracted position (zoom position 21 shown in Fig. 4). #40). After the stop position is set in step 34 or step 40, the processing flow moves to a zooming subroutine (136), and then moves to the main routine (#4).

Note that the drive direction set in steps #32 and #38 is specifically stored as data of 1 or O on the RAM of the control cPUI.

That is, 1 is set when the drive direction is the telephoto direction, and 0 is set when the drive direction is the wide direction.

Next, the collapsing operation of the photographic lens 12 will be explained. Collapsing the photographic lens 12 refers to storing the lens mirror t]21 in the camera body when the photographic lens 12 is not used. When the photographic lens 12 reaches the phase ratio position of the zoom position shown in FIG. 4, the photographic lens 12 is covered with a barrier 25 as shown in FIG. Note that when the zoom position of the photographic lens 12 is in the middle of collapsing as indicated by 20, the barrier 25 is half-open, so that it is impossible to take a photograph.
It is J-Noh.

Next, remote control signal discrimination will be explained with reference to FIGS. 10A to 11. First, the remote control signal branch will be explained with reference to FIG. 11')A. This figure shows a received signal RMC when a remote control signal is received.

First, one word becomes "H" for 10 m5 (remote control start signal). The time of 10 m5 is sufficiently long compared to the n and 7 times required for determining each switch in the above-mentioned main routine. This signal controls the CPU
I moves the program to a remote control determination routine.

Next, the remote control mode data is sent to "Ll" for 1 ms, and then remote control mode data is sent in 3 bits to "Hl" or "Ll" every 1 rn s.The remote control mode data and its contents are sent to the 10th
Shown in Figure B. For example, when the remote control mode data is OOO, the camera does not perform auto zoom but only releases the camera. Also, the remote control mode data is 001.01.
When the value is 0.011.100, the release is performed after performing auto zoom, but depending on the size of the data, the size of the subject is set to the desired size by the photographer (described later). , perform the release. These signals are sent to the operation switches S13 to S13 on the lens cap mentioned above.
S.

, corresponds to 1χ11, and the photographer can select it at will.

Next, a flowchart of the remote control determination routine will be described with reference to FIG. First, in #501, it waits for the received signal RMC to become L°.

After the 10m5 remote control start signal is output, “L”
When this happens, the program advances to #503, and from there the control CPUI waits for 1,5 ms. And receive 1g signal RMC
manually and store them in memory (#505, #507). Next, it is determined whether the 3-bit signal has been received or if it is a cup, and if the 3-bit signal has not been received yet, the program waits for 1 ms at #511, and the program returns to #
Proceed to 505 and repeat the above operations. When 3 bits are received (t=), the program proceeds from #509 to #513, and the mode is determined as explained in the first OB diagram.

Next, determine the necessity of auto zoom #515),
The auto zoom flag FAZ is set/reset (#517, #519). Here auto zoom flag F
AZ is a flag to perform auto zoom even in remote control mode, and when auto zoom is required, 1. becomes. Then, set the remote control flag FRMC to 1 #5
21), proceed to the S, ON routine described below. Here, the remote control flag FRMC is a flag for storing whether the shutter is released by the remote controller or the cup, and is set to 1 when the release is performed by the remote controller.

In this embodiment, the desired photographing magnification can be selected using the remote control, but auto zoom may not be performed during remote control photographing.

By doing so, the remote control signal is simplified, and the width of the remote control transmitting section is reduced to 11t.

Next, the processing flow when the photometric switch S is depressed or when the release is performed using the remote control will be described with reference to FIG. 12. When the photometry switch S is turned on by pressing the release button 11 to the first step,
Alternatively, when a release signal from the remote control is received, the processing flow moves to an AL light/distance measurement subroutine (#50), and then it is determined whether or not the AZ mode is in effect (#52). A
When it is determined that the mode is Z mode, the AZeL calculation subroutine (#54), AE calculation (#56), flash boost subroutine (158), and zooming subroutine (#54) are executed.
Each of the subroutines 60) is executed.

Similarly, AE calculation (#56) is similar to AZ calculation subroutine (#56).
54) is performed based on the zoom placement based on the calculation result. If it is determined in step #52 that the AZ mode is not in effect, it is determined in #53 whether FAZ is 1 or 0. FAZ-
If it is 1, the program advances to #54 and performs the above-mentioned operation. When FAZ-○, AE calculation (#62) is performed without performing AZ calculation, and flash boosting (#62) is performed.
64) is performed. After the zooming subroutine (#60) in AZ mode or the flash yrJ [<564) in non-AZ mode is completed, in #65 you can decide whether to release by remote control or apricot, and if the release is not by remote control, If the side light switch S1 is still on, the cup is turned off (#66). If the aF1 optical switch S is on, a check is made to see if the release switch S2 is on, and if the release switch S2 is off, flash boosting (#70) is performed again. The processing flow moves to step #66. If the release button S2 is on in step #68, or if it is determined that the remote control is used for the release in step #65, it is determined in step #69 whether or not the self mode is selected, and if the release button is in the cell mode, the release button S2 is turned on. After waiting for a while (#71), if the mode is other than self mode, immediately proceed to the next step. Then, the prism ($t72) (described later) performs minute zooming to ensure resolution, and after the focusing/exposure subroutine (#74) and one-frame winding (#76), the AZ-hour angle q division mode is disabled. 111 is cut off (#
78).

In the AZ-hour angle q division mode, the shooting mode changes from A Z -++:r angle q division mode to AZ mode (#80
), the current mode is displayed on the display LCD 15, and after setting the remote control flag FRMC to 0 (#83), the program shifts to the main routine. 7 at step #66
1p+optical switch S1 is off, or step #
If it is not the AZ-nl angle q division mode at step 78, the flag FRMC is similarly set to 0, and then the program moves to the main routine.

Nao, the method of displaying the mode on the display LCD 15 is as follows.
If in AZ mode, auto zoom mode display (Fig. 6)
d)) The segment indicated by 151 is lit and AZ-
If it is in time release mode, auto zoom mode display 151
is flashed at a frequency of 2Hz.

Note that this AZ-hour angle rl division mode is used in the following cases. For example, when you set the AZ mode, the camera determines the size of the subject (shooting magnification).However, there may be cases where you do not like this size.In such a case, operate the control lever 14 to zoom I, AZ-nor
If you set it to the angle-cutting mode, you can change the size of the subject by operating the same lever as you would with a normal zooming samurai.

FIG. 13 shows a subroutine when the auto zoom mode switch S3 is turned on. Referring to FIG. 13, when the auto zoom mode switch S is turned on, it is determined whether the AZ mode is selected (#90). If it is determined that the mode is AZ mode, the shooting mode is switched from AZ mode to normal mode (#92). Step #90
If it is determined that the camera is not in AZ mode, the shooting mode is set to AZ mode if it is normal mode or AZ-time release mode (#94), and it is determined whether the zoom lens is equipped with a teleconverter. (#98
), if it is determined that the teleconverter is included, the processing flow moves to step #92. If the teleconverter is not included, the self mode is canceled regardless of whether it is in the self mode or not (#100). Remote control mode is also canceled. And the processing flow is #9
6, and the shooting mode at that time is displayed as shown in FIG.

Note that the determination in step 98 as to whether or not the teleconverter is attached is made using the teleconverter switch S, which is switched by the teleconverter disposed near the photographic lens 12.
This is determined by the on/off status of l+. Note that step 98
The reason why the AZ mode can be switched to the normal mode when a teleconverter is installed is as follows. In cameras that do not have interchangeable lenses, to which this invention is applied, a front converter is generally used, which is large and heavy. Therefore, when zooming is performed under such conditions, the load on the zoom motor M1 becomes large and the zoom speed becomes slow. Therefore, it takes a long time for auto-zooming to take place between 1 and +1, and the time lag when pressing the release button becomes large, making it impossible to take a photograph at a good timing.

Next, refer to Fig. 14 and press jjQ L to set the shooting mode switch 5.
The subroutine when 12 is on will be explained. If the shooting mode switches S and 2 are on, the self mode or white mode is first turned off by +11 (#110), and if it is self mode, the mode is changed from self mode to remote control mode (#112), and the self mode is switched off by +11 (#110). If it is not the mode, the remote control mode or the cup is cut off by +11 (#11'3). If it is not in remote control mode, that is, in normal mode, self mode is set (#114), AZ mode or AZ-n: '7 angle q division mode is changed to shooting mode or normal mode (#116), and the program is set. The process moves to #118. When in remote control mode, the remote control mode is changed to normal mode (#115).
, the program moves to #118. The photographing mode in this state is then displayed on the display LCD as shown in FIG. 6 (#118). After that, the processing flow moves to the main routine. Therefore, duplicate settings of self mode, remote control mode, and AZ mode or AZ-11476 exclusion mode are not performed. However, it is possible to perform odozoom in remote control mode.

FIG. 15 shows a subroutine when the zoom-in/out switch S4 shown in FIG. 1 is operated and either the zoom-in switch S4 or the zoom-out switch S is turned on. When either the zoom in switch S or the zoom out switch S5 is turned on, the shooting mode changes to AZ.
mode or not is rejected ($t120), and if it is in AZ mode, the shooting mode is switched from AZ mode to AZ -u:; release mode (#122), and the mode display changes to +.
1 is called (#124). If it is determined in step #120 that the mode is not in the AZ mode, or after the mode is displayed in step #124, the zoom-in switch S
4 is on or not. Zoom in switch S4
If is on, the driving direction of the photographing lens 12 is set to the telephoto direction (9134), and the photographing lens 12 is set to the stop position or the telephoto end (#136). If zoom in switch S4 is off, zoom out switch S5
If the fortune-telling is turned on and the zoom out switch S5 is turned on, this is an instruction to zoom out, so the driving direction of the photographing lens 12 is set to the wide direction (6130), and the photographing lens 12 is set to the wide direction (6130). The stop position is set to the wide end (1132). Stop of photographing lens 12] 14
After the position is set to one of the above positions, the processing flow moves to a zooming subroutine (#138). If the zoom out switch S is turned off in step #128 or after zooming is completed in step #138, the processing flow returns to the main routine.

Note that if the zoom-in switch S and the zoom-out switch S are both off in steps #126 and #128, this is a case where an erroneous signal such as noise has been input. Further, the setting of the stop position of the photographing lens 12 is as shown in #34 and #40 in FIG.
The zoom position data is stored on the RAM of the control CPU as shown in FIG.

Next, the zooming subroutine will be explained with reference to FIG. 16. When the zooming subroutine is called, the zoom position is first read (#140),
It is determined whether the photographing lens 12 has reached the telephoto end, wide end, or AZ stop position (#142). When it is determined that it is not at the stop position,
Depending on the driving direction of the photographing lens at that time, if it is in the telephoto direction, ZCWl, No. 4 is output (#146), the zoom motor M is rotated forward, and if the driving direction is in the wide direction, ZCW1 is output (#146).
CCCC signal is input (#148), zoom motor M,
is reversed, and it is determined whether the mode is AZ mode or not (#150
). When it is determined in step #150 that the mode is AZ mode, it is determined whether or not the release switch S2 is on (#
152), if release switch S2 is off, Jl
It is determined whether the optical switch S is on or not (#1
54). If the photometry switch S is on in step #154, the zoom position is read (#154), and it is determined whether the photographic lens 12 has reached the stop position (#15).
8). If the pH is cut off in step #150 unless the AZ mode is selected, it is determined whether the zoom-in switch S4 or the zoom-out switch Ss is on (#160
), if it is turned off, the processing flow moves to the zoom position reading subroutine (#156). If step #158 is not at the stop position, turn the main switch S.

If it is determined that the power is on or not, the processing flow returns to step #150.

When the illumination is cut off in step #160 when the zoom switches S4 and S5 are not on, or when the illumination is cut off in step #162 when the main switch So is off (
#]62) applies a brake to the zoom motor M, so the processing flow moves to step #164. When it is determined in step #152 that the release switch S2 is on, the brake is applied to the zoom motor M (#152).
172), waits for 0.1 seconds (#174),
Stop outputting the brake signal to the zoom motor M.#
176), AE calculation is performed (#178). In this case, although the mode is AZ mode, the photographing lens 12 has not been moved to the original target position for photographing the subject, so the AE calculation at the zooming stop position will be performed +li degrees. The reason why the AE calculation is performed by +1 degree is because the open F value of the photographing lens 12 differs depending on the zoom position.

J at step #154? + When it is determined that the optical switch S is not on, the processing flow moves to step #164 to apply a brake to the zoom motor M. In other words, referring to steps #150, #152, #154, and #164, even when zooming in AZ mode, when the δ-1 optical switch S is turned off, the zoom motor M1 is immediately turned off. The brakes are applied and activation and deactivation of autozoom is controlled by the user. Therefore, there is no difference in the timing of manual camera operation during photographing, and a camera capable of auto zoom-11J can be provided, which allows the user to take photographs without feeling discomfort.

In order to brake the zoom motor M in step #164, the zcw and zccw signals are output.As shown in Table 1, by setting both output signals to L, the motor is braked. This is because it takes

When the brake is applied to the zoom motor M, 0.
The brake is applied for one second (#166), and the false operation of the zoom motor M is stopped (#168). Thereafter, the processing flow moves to an overrun check subroutine (#170) to check whether the photographing lens 12 has overrun the focused position.

Next, the 17th section regarding δpl destination/71F+distance subroutine.
This will be explained with reference to the figure. In the 71P1 light/ill forceps subroutine, an AFES signal for turning on the 7111 light/ill forceps circuit is first output (1180). Next, a serial communication clock SCK signal is output as an operating clock for A/D conversion (#182),
After a predetermined number of clocks have been output, a C5I signal is output to specify the data transmission destination (#184). Next, photometry 71
? I AFES signal output stopped to set 1llu data1. (#186), and the SCK signal, which is a serial clock, is output (#188).

AFE to read photometry/distance data in synchronization with this
After No. D12 is manually operated (#190) and reading of photometry/distance measurement data is completed, the output of the C5I signal is stopped in order to turn off the 71-1 light/distance measurement four-way (#192).

The signal timing etc. in the above-mentioned 11-to-1 optical distance measurement operation will be explained with reference to FIG. First, in Figure 18 (
Referring to 1), when the AFES signal becomes L, photometry and distance measurement are started. When the AFES signal becomes L, the SC, which is the operating clock of the 71Pj optical/-P1 distance circuit, synchronizes with this.
The K signal emits 512 pulses per cycle.

During this time, A/D conversion of the photometer and distance measurement values is performed. And when C511g becomes L, SCK pulse 1m
The signals are synchronized and the AFED outputs photometric data and ranging data to the control CPU 1 in that order. Both of these data are transferred as 8-bit serial data. For example, the relationship between the pulse of the serial communication clock SCK when the 71111 optical data (1) is output and the AFED output at that time is shown in an enlarged manner at the bottom of (1) in FIG. 18. Referring to the AFED diagram, 1 of the SCK signal
One bit of 71?1 optical data is transmitted every cycle. Details of the JFJ optical data and Apj distance data are described in (2) of FIG. Referring to this figure, although the photometric data is 8-bit data, the upper 5 bits represent an integer and the lower 3 bits represent a decimal. This data is a BV value and represents the brightness of the subject.

Although the Apt yb data is 8-bit data, only the lower 5 bits are used, and this distance data represents the distance to the subject using a predetermined zone number. Distance to this subject and 11 at that time
FIG. 19 shows the relationship between the p1 distance data and the zone number.

FIG. 20 is a flowchart showing the subroutine of AZ calculation. Referring to FIG. 20, when the processing flow is transferred to the AZ calculation subroutine, filtering (#
20(1) is performed and a reference table is created (
#202).

This filtering' is performed for the following purpose. When auto zooming is performed continuously, the subject may move out of the distance measurement area. In this way, if the subject moves out of the measurement yB area, the distance to the green rice will be apjy
t, resulting in a zoom state where the subject is at infinity, and the zooming operation becomes less smooth. Especially when the subject is moving, there is a high probability that this phenomenon will occur.

Therefore, by filtering the dll MLi data, distance measurement data that does not include the subject distance will be invalidated.
This is done to make the zooming operation smooth.

As a method for this filtering, for example, when a plurality of the same data are obtained in the same amount, a method is considered in which that data is used as a white effect. In other words, if there is unexpected data among a plurality of consecutive data, that data is invalidated. However, this method cannot be applied when the subject is moving forward and backward relative to the camera. Another method is to compare the distance measurement data from the previous time, and if the difference is greater than a certain value, the current data is invalidated. The latter method has the advantage that even if the distance measuring circuit itself has an error of about ±1 zone in the distance data, such aFI distance error can be absorbed.

Next, the reference table will be explained. The reference table is a table for referring to the zoom stop +1 position when the subject distance is in the AZ mode.

An example of such a lookup table is shown in FIG. Referring to Figure 21, the reference table is table (1)
and table (2). Table (1) shows the distance data determined based on the subject distance shown in FIG.
This is for reference. This parameter D represents the actual distance in units of mrT1. The product of this parameter D and the magnification data β determined in advance according to the shooting mode is calculated to determine the black point! ! Ui! ftf- is defined.

Data (2) is A based on the focal length f which is the calculation result.
The stop position of the photographing lens during Z mode is expressed as a zoom position. Both table (1) and table (2) are created on the RAM of the control CPUI.

In remote control mode, the auto zoom magnification can be selected depending on the content of the received signal. Number of people photographed (1
(one person, two people, three people, many people), and the predetermined shooting magnification β is set in each mode.
have. For example, if the number of subjects is one, β-173
0, for 2 people it is β-1150, for 3 people it is β-1/70, and for many people it is β-1/120.
It has a predetermined imaging magnification β. The focal length f is calculated by calculating the product of this imaging magnification β and the parameter D. FIG. 22 shows an example of auto-zooming during remote control photography.

Returning to the AZ calculation routine in FIG. 20, after the black spot distance I4f corresponding to the stop position is determined (#204), the driving direction of the photographing lens is calculated (#206). Note that this drive direction calculation is performed by comparing the current stop position of the photographing lens and the stop position corresponding to the determined sunspot l distance f using the stop positions in table (2) shown in FIG. Determined by

Next, the AE calculation subroutine will be explained.

FIG. 23 is a flowchart of the AEM calculation subroutine. Referring to FIG. 23, in the AE calculation subroutine, it is first determined whether the shooting mode is the AZ mode (#210), and if it is the AZ mode, it is determined whether the release switch S2 is turned on. It is (#224)
, if the mode is not AZ mode or the release switch S2 is turned on, the zoom position is read (#212
).

Note that the reason why it is determined in step #224 whether or not the release switch S2 is turned on is to determine whether or not shooting is being performed with release priority.

After the zoom position is read in step #212, the aperture F value is determined. The reason why the aperture F value is determined after the zoom position is read in this way is that the aperture F value of the photographing lens 12 is different from the zoom position. Note that if the release switch S2 is off in step #224, A
The open F value is adopted at the stop position as a result of Z calculation (
#226), the processing flow moves to step #214. Incidentally, a table (3) showing the relationship between the zoom position and the open F value (AVo) is shown in FIG. Furthermore, the table (3
) is provided on the ROM or RAM of the control CPUI.

Next, return to the AEf calculation subroutine, and after the open AkF value is determined, IS 01. '7 report is read (#2
16), the shutter control value is calculated (#218), the state of charge is read (#220), and other AE information is displayed in the viewfinder (#222).

Figures 25A and 25B are step #216 in Figure 23.
FIG. 2 is a diagram specifically explaining how to read information from 5IO4i' described in FIG. The IsO sensitivity indicating the sensitivity of the film and the corresponding ISO code are as shown in FIG. 22A. The ISO sensitivity is expressed as an Sv value, and the Sv value for the ISO sensitivity is shown in parentheses next to the ISO sensitivity. Next, a method of converting the ISO code to 5vrIfi will be explained with reference to FIG. 25B. When ISO information is read, first the ISO code is read as the lower 3 bits of 8 bits. In this case, the data of the upper 5 bits is 1. This state is shown in No. 25B (1). next(
The data shown in 1) is inverted and shown in Figure 25B (
2). In addition to this, Figure 25B (3
), 03H is added, and the film sensitivity Sv
converted to a value. This value corresponds to the value given in parentheses next to the IsO sensitivity in the film sensitivity table shown in FIG. 25A. Next, the shutter control value calculation shown in step #218 in FIG. 23 will be explained. The shutter control EV value EVc is EVc-BV+Sv-(AVo(fx)-AV
.

(f-38)) ... (1
).

This shutter control EV value changes the zoom position to the focal length fX
This is the case when expressed as . In addition, here, EVc: shutter control EV value BV: photometric data representing the subject's flexibility (see Figure 18) Sv: film sensitivity (see Figure 25) AV (fx): zoom position (fish focal length M) Open f-number AVo (f-38) when fxmm: This is the open f-number when the focal length is 38 mm, that is, at the wide end.

That is, the control EV value represents the control EV value when comparing the case where the photographing lens 12 is at the wide end. When the calculated EVc is smaller than EV, which is the threshold value for determining whether to use flash mode or not, the photographing mode is automatically set to flash mode. The above is the AE calculation.

Next, eL calculation in flash mode will be explained.

In the flash mode calculation, a shutter control (flash emission) AV value AV specific to the flash mode is determined. The calculation formula is AVT-IV+Sv DV (AV (fx)A
V (f-38)) ... (2). Here, IV: represents the flash illuminance, and is expressed as the logarithm of the guide number.

DV: represents the distance to the subject and is expressed as the logarithm of foiif.

The shutter control AV value in the flash mode calculated as above is calculated as shutter control EV1
It is converted to .

EVc=F(AVT)-(3) where F() represents a function.

FIG. 26 is a flowchart showing the contents of the pre-zoom subroutine. Here, pre-zoom means that the lens barrel 21
This is an operation to keep the play between the cam groove 1 and the pin 33 always in the same direction.

FIG. 27 is a sectional view of the lens barrel section. Referring to FIG. 27, vi, the cylinder 21 is provided with a cam ring 32, and the cam ring 32 is provided with a cam groove 31. The pin 33 is moved along the cam groove 31 via a lens frame 34 provided on the outer periphery of the photographic lens 12 so that the photographing lens 12 is moved along the cam groove 31 to a predetermined sunspot distance. Ru.

As shown in FIG. 27, the width of the pin 33 is smaller than the width of the cam groove 31. Therefore, depending on the direction of movement of the photographic lens 12, there is a certain play r7, and even if the mirror i21 is rotated by the zooming motor M1, the amount of concave rotation of the zooming motor M is not proportional to the amount of movement of the photographic lens 12. . FIG. 27(a) shows the positional relationship between the pin 33 and the cam groove 31 when the zoom direction is the wide direction, and (
b) shows the relationship when the zoom direction is the telephoto direction.

Refer to FIGS. 27(a) and (b). Therefore, if the zoom direction is different, an error of Δd will occur in the lens position even at the same zoom position, and the optical performance will deteriorate.
When the zoom direction in a) is the wide direction, fine zooming is performed in the telephoto direction at the initial stage of release, and the lens is always in the state shown in FIG. 27(b), that is, by reducing play in the same direction, the lens at the same zoom position is The positional error Δd is virtually eliminated.

Returning to the flowchart of the brizoom shown in FIG.
Since it is necessary to perform a pre-zoom to eliminate the error of d, a ZCW signal is outputted to rotate the zoom motor M in the forward direction (#252). Next, a certain rotation time (Δ
T1) is secured (#254), and in order to brake the zoom motor M1, ττ page, ZCCW(, n is output (#256), and after the predetermined braking time (ΔT2) is secured ((# 258>, the outputs of zcw and zccw<= are stopped 1 in order to turn off the zoom motor (#260).In addition, if the previous zoom direction is in the wide h direction in step #250, a brizoom is performed. Since it is not necessary, the processing flow returns as is.

Note that the braking time (ΔT2) is shorter than the time (ΔTs) required to actually stop the motor rotation. This is to minimize the time lag in the Lelys River.

It's actually a zoom motor M.

is stopped in a lens cellar 1-(d) which will be explained later. Further, by configuring the drive power source with a constant voltage or constant current circuit, the amount of movement of the photographic lens 12 can be kept constant at all times.

FIG. 28 is a flowchart showing the focusing/exposure subroutine. Focusing and exposure are carried out by simply transmitting focus data and shutter control data to the shutter block 3 and outputting an STR signal instructing the start of focusing.

Referring to FIG. 28, in the focusing/exposure subroutine, the data output edge is first specified, and the C52 signal is output to turn on the shutter block (#22
8). Next, the serial communication clock signal SCK
A signal is output (#282), focus data (lens set data), and shutter control data are output (#28
4) An STR signal is output for a command to start m-point alignment (#286). Next, the process waits for a predetermined time until the exposure (exposure) is completed (#288), and the output of the STR signal is stopped in order to turn off the shutter block 3 (#290).
, the output of the C52 signal is stopped (#292), and the LED display of the finder (not shown) is turned off (#2')4
).

In addition, the flash trigger tg in the case of flash mode
No. TRG (see FIG. 5) is automatically output from the shutter block 3 to the flash block 5 by setting the shutter control data pin 1-7 (b7).

Next, the zoom position reading subroutine will be explained. FIG. 29 is a flowchart showing the zoom position reading subroutine. Referring to FIG. 29, in the zoom position reading subroutine, a reference table (4) is first created (#300), a hexadecimal signal from the zoom encoder is read (#302), and the number is used as an address. , the zoom position data is accessed, and the zoom position is determined (#304).

FIG. 30 is a diagram showing the zoom position reading reference table (4) described in step #300 of FIG. 29. 30th
Referring to the figure, the address is represented using 5 bits of 8 bits, and the address represented by 2 digits of 16 runs corresponds to decimal zoom position data. Next, we will explain how to read this table by giving an example. For example, when 13H is read as a zoom encoder signal, zoom position data 8 (decimal) is obtained using this 13H as an address. In this case, from the zoom encoder explanatory diagram of FIG. 4, the representative f value is 7 Q m m. Note that the fact that the zoom position data is 0 indicates that the zoom position data is impossible.

Next, the overrun search subroutine will be explained. FIG. 31 is a flowchart showing the overrun check subroutine. In the case of overrun, if the photographing mode is AZ mode, the photographing lens is redriven until it reaches the target position, and if it is not AZ mode, it is redriven only when it is at an irregular position. Note that the irregular position here means that the photographing lens 12 is located between the wide end and the retracted position.

In the overrun check subroutine, the zoom position is first read (#310), and it is determined whether the read zoom position is the stop position of the photographic lens 12 (#312), and if it is not the stop position, the AZ mode is selected. It is determined whether the position is an irregular position (#314), and if it is not the AZ mode, it is determined whether the position is an irregular position or not (#316), and if the position is not an irregular position, the processing flow returns. Step #
If the zoom position read in step 312 is f'>normal position, the process returns directly. When the AZ mode is determined in step #314, the drive h° direction is calculated from the stop position (#-320) and zooming is performed (#322). If it is determined in step #316 that the position is irregular, the escape from the irregular position is l.
! :(Since the lens is driven in the telephoto direction, the driving direction of the photographing lens 12 is set to the telephoto direction (#
318). Then, zooming is performed (#
322).

Next, the driving direction calculation subroutine will be explained. Third
FIG. 2 is a flowchart of the driving direction calculation subroutine. Referring to FIG. 32, in the drive direction calculation subroutine, the zoom position is first read (#340).

Next, it is determined whether the zoom position is larger than the stop position by comparing the sizes of the numbers at the stop position (
#342). When it is determined that the zoom position is larger than the stop position, the drive direction is set to the telephoto direction (#344), and in the opposite case, the drive direction is set to the wide direction (#346). This driving direction is determined by the control CPU.
1 RAM.

FIG. 33 is a diagram for explaining the release timing when the zoom is performed.

Referring to FIG. 33, when the release switch S2 is turned on, the zCW for starting rotation of the zoom motor M.
A signal is output, and then a ZCCW signal for stopping the zoom mode M is output. The speed change of the zoom motor M at this time is written next to Ml in FIG. 33. Referring to this figure, when the release switch S2 is turned on, the zoom motor M1 starts normal rotation f: 3 and in response to the brake signal, a bli-zoom is performed, and after that, the zoom motor M1 undergoes inertial fixed rotation. Mourning 11-. This same rotation rising time is represented by (a), and the braking period is represented by (a).
b), and the inertial rotating intercostal space is represented by (C), as shown in the figure. When the BriZoom ends, a signal C52 designating the data transmission destination is output, and the signal is transmitted to the shutter block 3. In other words, the serial communication clock SCK is output, and in synchronization with this, the focus data,
An output signal 5HTD outputting shutter control data is output. After the focus data and shutter control data are output, a point alignment start command signal STR signal is output.

As a result, the black point alignment shown in the lower part of FIG. 33 is started, and the lens is set for the black point alignment.

The period required for this lens set is, for example, approximately 150 m.
This period is expressed as (d). After focusing is completed, the shutter is opened and closed. Before the shutter is opened and closed, a lens stabilization period (e) for stabilizing the lens is maintained, and then exposure (f) is performed. Referring to the operation diagram of the black point alignment signal and the zoom motor M in FIG. 33, the brizoom and the accompanying smooth rotation of the zoom motor M1 must be completed before the focusing is completed.

That is, the time indicated by ΔT in the figure needs to be constant. Note that after the release switch S2 is turned on,
The release time lag until focusing is completed is about 0.4 seconds at most.

Next, the timing f6 of transmitting data to the shutter block at release 1 shown in FIGS. 33(e) and 33(g) will be explained. FIG. 34A is a diagram showing details of data transmission (5 timings) to the shutter block attached to the release.

Referring to FIG. 34, when a signal C82 designating a data transmission destination to the shutter block is output, a serial communication block SCK is output in synchronization with this. In response to each cycle of this serial communication clock 5CK (No. 4), 8-bit shutter data 5HTD is serially output in the order of focus data and shutter control data. After that, the focusing start command signal STR is output.The contents of the shutter data 5HTD will be explained with reference to FIG. 34B.The shutter data 5HTD includes focus data and shutter control data Evc.Focus data,
Both shutter control data EVc are 8-bit data, but the focus data uses the lower 5 bits of the 8 bits, and the upper 3 bits are set to 0. In the shutter control data Evc, the most significant bit indicates flash mode or non-flash mode, the next 5 bits represent an integer, and the lower 2 bits represent a decimal. In addition,
If the most significant bit is 1, a represents flash mode,
A value of 0 indicates non-flash mode.

Next, details of the shutter control data Evc explained in FIG. 34B will be explained with reference to FIGS. 35A and 35B. FIG. 35A is a graph in which the aperture value (F value) is plotted on the Y axis and the shutter opening time is plotted on the X axis. Referring to FIG. 35A, the smaller the aperture value (F value), the longer the shutter opening time To becomes. The area of the triangle in FIG. 35A depends on the exposure amount.

FIG. 35B is a diagram showing an example of Evc values of shutter control data. Referring to Figure Fj435B, once the shutter control data EVc value is determined, the corresponding shutter opening time To is set. In this case, the shutter opening time To is expressed in ms vehicle position.

Next, another example of the remote control shown in FIG. 2B will be described. FIG. 36 is a diagram showing an example of a modified length of the remote control device shown in FIG. 2B.

The remote control 30', which also serves as a lens cap, has a mark 30'a indicating a person's face to shoulders, a mark 30'C indicating the half of the body from the face to the copper, and a mark 30 indicating the whole body.
' d, and includes restraint buttons S13', S15' and S16' arranged corresponding to each mark. This remote controller 30' sets the photographing magnification β of the camera body to 1/30 when the push button 813' is pressed, and changes the photograph magnification β to 1/70 when the push button S15' is pressed.
When the push button 816' is depressed, the photographing fj
Each remote control command No. 4m is output so that lβ is 1/120. The camera body drives these remote controllers (No. 2 and zoom motor M depending on the shooting distance to the subject) and presses pushbuttons 813', 815' and 8.
When 16' is suppressed, the magnification is 1/30 to capture the subject's face to shoulders, and the magnification is 1/7 to capture the V body.
The photographing lens 12 is driven so that the photographing magnification is 1/12.0 and the whole body is photographed.

[Effects of the Invention] As described above, in the camera according to the present invention, the remote control transmitter for remotely controlling camera photography is sunk into the lens cap of the photographic lens. Therefore, it is possible to provide a camera that has a detachable remote control and whose overall size remains almost the same.
