Abstract

PURPOSE:To make the title device easy-to-handle by stopping only the actuation of a zooming sequential photographing means without releasing the set of a zooming sequential mode when a releasing signal for the zooming sequential photographing is outputted during the zooming sequential photographing. CONSTITUTION:During the sequential photographing by the zooming sequential photographing means 106; for example, when the releasing signal is released, the releasing signal for the zooming sequential photographing is outputted, then a controller 107 stops the zooming sequential photographing. Since the set of the zooming sequential photographing mode is not released even if the half-operation of the release operating member 101 is released at this time, the zooming sequential photographing is actuated by the continuous operation of the release operating member 101 without the reoperation of the setting means 105 of the zooming sequential photographing.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to an operation control device for a camera capable of so-called zoom continuous shooting in which the focal length is changed frame by frame.

B. Conventional technology For example, by operating an operating member such as a zoom continuous shooting button to set the zoom continuous shooting mode and then pressing a release button, the focal length of the zoom lens is sequentially changed to a predetermined value and a predetermined frame is set. The applicant previously proposed a camera capable of so-called zoom continuous shooting, in which multiple images are taken in succession.

C1 Problem to be Solved by the Invention However, in this already proposed zoom continuous shooting camera, when shooting is started in zoom continuous shooting mode by operating the release button, the operation of the release button is stopped in the middle of zoom continuous shooting. However, continuous shooting will continue until a predetermined number of frames have been captured, so even if the photographer wants to stop zoom continuous shooting for some reason during zoom continuous shooting, the user cannot cancel the zoom continuous shooting. This results in undesirable photos being taken.

SUMMARY OF THE INVENTION An object of the present invention is to provide a camera operation control device that allows a photographer to cancel continuous zoom shooting at his or her will.

To explain with reference to FIG. 1(a), which is a means-claim correspondence diagram for solving the D0 problem,
The camera operation control device according to claim 1 includes a release signal output means 102 that outputs a release signal for commanding a shirt release in conjunction with the operation of the release operation member 101.
, a driving means 104 for driving the photographing lens 103 for zooming, a zoom continuous shooting mode setting means 105 for setting the zoom continuous shooting mode, and a driving means 104 for driving the photographing lens 103 for zooming; a zoom continuous shooting means 106 that performs zoom continuous shooting to continuously shoot a predetermined number of frames while sequentially changing the focal length of the camera to a predetermined position; and a zoom continuous shooting means 106 that sets a zoom continuous shooting mode when a zoom continuous shooting cancel signal is output during zoom continuous shooting. The control means 107 suspends only the operation of the zoom continuous shooting mode without canceling the zoom continuous shooting mode, and continues to maintain the zoom continuous shooting mode setting even if the operation of the release operation member is released.

In addition, the invention of claim 2 is capable of printing a so-called pseudo This is for zooming. The invention of claim 2 for Meng provides a trimming mark TM used when printing for pseudo zooming.
The zoom continuous shooting means 106 sequentially changes the magnification of pseudo zooming in response to the output of the release signal when the zoom continuous shooting mode is set. Zoom continuous shooting is performed in which a predetermined number of frames are continuously shot while changing the TM sequentially.

Furthermore, claims 1 and 2 may be combined.

If, for example, the release operation is canceled and the release signal disappears during continuous shooting by the zoom continuous shooting means 106, a zoom continuous shooting cancellation signal is output, and the control means 107 interrupts the zoom continuous shooting. At this time, even if the half-press operation of the release operation member 101 is released, the setting of the zoom continuous shooting mode is not canceled, so if you continue to operate the release operation member 101 without operating the zoom continuous shooting setting means 105 again, the zoom continuous shooting mode will be set. is executed.

F. Embodiment An embodiment of the present invention will be described based on FIGS. 2 to 4.

In Figure 2, C which controls the entire camera sequence.
The PUI includes a distance measuring circuit 2. Photometry circuit 3゜Exposure control circuit 4
A focusing motor 6, a zooming motor 7, and a film winding motor 10 are connected to the motor drive circuit 5. The distance measurement circuit 2 calculates and outputs distance measurement information regarding the distance to the object, and the photometry circuit 3 calculates and outputs brightness information regarding the brightness of the object. The CPU calculates the lens movement amount for focusing based on the ranging information, and uses this lens movement amount to drive the motor 6 via the motor drive circuit 5.
to drive the photographic lens and perform focusing. Further, the CPU determines an exposure value based on photometry information, film sensitivity, etc., and controls an exposure control member (not shown) to take a picture using this exposure value via the exposure control circuit 4.
After exposure, the film is wound up by a motor 10.

Further, switches SW1 and SW2 are connected to the CPUI, which are linked to the operation of a release button (release operation member) not shown. Switch SW when the release button is pressed halfway
I is turned on, and switch SW2 is turned on when it is fully pressed.

The CPU turns on the above-mentioned distance measuring circuit 2 by turning on the switch 71 SWI. The photometry circuit 3 is activated, and the motor drive circuit 5 and the exposure control circuit 4 are activated in response to a release signal output by turning on the switch SW2.

Furthermore, a display circuit 9 of a liquid crystal display (LCD) 8 and a zoom continuous shooting mode setting switch SW3 are connected to the CPUI. This switch SW3 is turned on in conjunction with the operation of a zoom continuous shooting mode setting button (not shown), and the CPU 1 sets the zoom continuous shooting mode by turning on the switch SW3, and displays a display to that effect on the LCD 8 via the display circuit 9. conduct.

When this zoom continuous shooting mode is set, the CPUI sequentially changes the focal length of the photographing lens to a predetermined value using the zooming motor 7 via the motor drive circuit 5, and continuously photographs a predetermined number of frames. Also, during zoom continuous shooting, switch SW
2 is turned off, that is, when a zoom continuous shooting cancel signal is output, the CPU 1 cancels the zoom continuous shooting mode. Furthermore, if the switch SW1 is also turned off during zoom continuous shooting, the zoom continuous shooting process is temporarily stopped while the zoom continuous shooting mode is maintained. Therefore, when the switches SWI and SW2 are turned on by operating the release button again, continuous zoom shooting is performed.

In this example, the focal length of the photographic lens is set to 35 mm,
The distance will be changed to 50mm and then 80mm, and images will be taken at each position. That is, three consecutive frames are photographed.

In the configuration of the above embodiment, the full-press switch SW2 controls the release signal output means 102, the motor drive circuit 5 and the motor 7 control the drive means 104, the switch SW3 and CPUI control the zoom continuous shooting mode setting means 105, and the CPU
1 and the exposure control circuit 4 control the zoom continuous shooting means 106,
Each PU1 constitutes a control means 107.

Next, according to flowchart 1 in FIGS. 3 and 4,
The control procedure using the PUI will be explained.

Figure 3 shows an example of the procedure for setting and canceling zoom continuous shooting mode,
This is executed by turning on the switch SW3.

First, in step S51, it is determined whether the zoom continuous shooting mode has already been set. If the answer is negative, the zoom continuous shooting mode is set in step S52, and in step 853, the count value K of the zoom continuous shooting counter is reset. Next, in step S54, it is determined whether the switch SW3 is on or not. If it is on, the process remains in step S54, and if it is off, the process returns to another procedure. On the other hand, if step S51 is affirmed, the zoom continuous shooting mode is canceled in step S55 and the process proceeds to step S54.

Next, FIG. 4 shows the procedure executed by turning on the half-press switch SW1.

First, in step S2, the count value K of the zoom continuous shooting counter is set to zero. Next, in step S3, photometry information from the photometry circuit 3 and distance measurement information from the distance measurement circuit 2 are read, and the process advances to step S4. In step S4, it is determined whether the zoom continuous shooting mode is set, and if the affirmative determination is made, the process proceeds to step S5, and if the negative determination is made, the process proceeds to step S.
Proceed to ll.

In step S5, 1 is added to the count value K, and then in step S6, the value of the count value is determined. If K=1, the focal length of the photographing lens is set to 35 mm in step S7, if K=2, it is set to 50 mm in step S8, and if K=3, it is set to 80 mm in step S9, and in step S1
0, the photographing lens is driven to the set focal length by the motor 7 via the motor drive circuit 5. In other words, zooming is performed.

Next, in step Sll, it is determined whether or not the fully pressed switch SW2 is turned on, and if an affirmative determination is made, step S1
Proceed to step 2. In step S12, focusing is performed based on the read distance measurement information, and the exposure control circuit 4 is controlled based on photometry information, film sensitivity information, and lens brightness information (F number information) according to the set focal length. Then, in step S13, the motor 1o is driven to rotate the film 1.
The piece is wound up and the process proceeds to step S14. In step S14, it is determined whether or not the zoom continuous shooting mode is in effect. If the determination is negative, the process proceeds to step S17, and if the determination is affirmative, it is determined in step 815 whether or not the count value K is 3.

If a negative determination is made in step S15, the process returns to step S3 and the processes from step S3 onwards are repeated, and if an affirmative determination is made in step S15, the zoom continuous shooting mode is canceled in step S16, and the process proceeds to step S17. In step S17, it is determined whether the half-press switch SWI is turned on. If a positive determination is made, step S17 is continued until a negative determination is made.
remains, and if it is denied, the process is terminated.

On the other hand, if step Sll is denied, that is, if it is determined that the full-press switch SW2 is turned off after zooming in step SIO, the process advances to step 818;
Determine whether the half-press switch SWI is on. If an affirmative determination is made, the process returns to step Sll, and if a negative determination is made, the process proceeds to step S19. In step S19, the count value K
Set it to zero and return to another step. Half-press switch S
Even if W1 is turned off, the zoom continuous shooting mode is still maintained.

As described above, in this embodiment, during continuous zoom shooting, each time the photographic lens is moved to a predetermined focal length, the switches SWI and S
The state of W2 is detected, and if switch SW2 is off, zoom continuous shooting is stopped. Further, when the half-press switch SW1 is also turned off, only the zoom continuous shooting counter is reset to zero without canceling the zoom continuous shooting mode, and the process ends. Therefore, if the full-press switch SW2 is turned on, a predetermined number of frames will be photographed by zoom continuous shooting, and the release button will be released from the full-press operation during zoom continuous shooting, and the switch SW2 will be released.
You can cancel continuous zoom shooting by turning off. At this time, if switch SWI is on, that is, if the release button is pressed halfway, zoom continuous shooting will be temporarily interrupted, but the count value will be maintained, and switch SW2 will be activated by pressing the release button fully again. When turned on, continuous zoom shooting will continue from the number of frames where it was interrupted.

Furthermore, when the switches SWI and SW2 are both turned off, zoom continuous shooting is stopped and the values are set to zero, but the zoom continuous shooting mode is not released. In other words, even if the composition during zoom continuous shooting is not favorable and the user cancels the half-press operation, the user often still has the intention to continue zoom continuous shooting, and in this case, the user does not need to operate the zoom continuous shooting button again. You can perform continuous zoom shooting from the beginning by pressing the release button all the way.

Moreover, FIG. 5 is a flowchart with only step S19 of FIG. 4 changed.

That is, when the half-press switch SWI is turned off during shooting with the zoom continuous shooting mode set, the process proceeds from step S18 to step S21, subtracts 1 from the count value K, and returns to other steps.

According to this procedure, if the half-press switch SW1 is turned on while the zoom continuous shooting mode is set and the half-press switch SW1 is turned off while the process shown in Fig. 5 is being executed, the zoom continuous shooting mode is maintained. Pause continuous zoom shooting and click 1.
~The value K is returned by 1. In this embodiment, 1 is added to the count value before shooting using zoom continuous shooting, so by subtracting 1 from the count value, the number of frames taken at the time of interruption of zoom continuous shooting is effectively held in the counter. Ru. Therefore, by zoom continuous shooting mode, the focal length is 35mm.
Half-press the switch S when you have finished shooting only one frame in mm.
When W1 is turned off, the count value K is returned to 1, so when the half-press switch SW1 is turned on again and this procedure is executed, the focal length of 50 mm is selected and the second frame continuous zoom shooting is performed. It is done. According to this, the frame speed of continuous zoom shooting can be increased according to the photographer's will, and usability is improved.

FIG. 6 shows an embodiment in which the present invention is applied to a camera capable of so-called pseudo zooming.

Pseudo zooming is described in, for example, US P4,652,10
As disclosed in Publication No. 4, instead of printing the entire area on both sides of one frame of film, a specific area is specified and that area is enlarged and printed to obtain a photograph similar to that obtained by zooming. . To do this, it is necessary to imprint a mark called a trimming mark in the margin of the film when shooting, and the camera has a built-in device for this imprinting. Then, a pseudo-zoomed photograph is formed by printing according to the cropping marks.

The camera shown in Figure 6 is a 35mm and 50mm bifocal camera with an 80mm pseudo-zooming function added, and during continuous zoom shooting, the focal length of the photographing lens is set to 35mm and 50mm for the first and second frames. The third frame is taken with the focal length of 50 mm, and a trimming mark is imprinted on the margin of the film so that the image obtained with the focal length of 80 mm is printed.

That is, if =3 is determined in step S6, a focal length of 80 mm is set as trimming data in step 831, and in step S32, the trimming mark is imprinted on the margin before exposing the film. After step Sll, photographing is performed according to the procedure shown in FIG.

FIG. 7 also shows an embodiment in which the present invention is applied to a camera capable of pseudo zooming. This is done using a single focal length camera, for example, with a focal length of 35 mm, and a focal length of 50 mm and 80 m.
This is to perform pseudo zooming of m.

That is, if =1 in step S6, photographing is performed by the processing from step Sll described above. If =2 or =3 is determined in step S6, trimming data for a focal length of 50 mm or 80 mm is set in step 833 or S35, and in step S34
In this step, a trimming mark is imprinted on the margin of the film, and the process proceeds to step Sll and subsequent steps.

In this embodiment, a release signal is output while the release button is pressed all the way down, and this release signal causes continuous zoom shooting to be performed, and when the release button is stopped being pressed all the way and the release signal disappears, the zoom starts. We have shown an example where the continuous shooting cancel signal is output and continuous zoom shooting is interrupted, but when you start shooting, press the release button all the way and press the release button once.
It is also possible to start continuous zoom shooting by generating the release signal only once in the form of a pulse. In this case, for example, when the release button is operated again during zoom continuous shooting, a zoom continuous shooting cancellation signal may be output. Alternatively, the continuous zoom shooting cancel signal may be output by operating a separate interrupt switch.

Furthermore, although the above example shows an example in which the number of frames and focal length during zoom continuous shooting are set in advance within the camera, the number of frames and focal length can be changed externally using an operating member. The present invention can also be applied to cameras that can.

G0 Effects of the Invention According to the present invention, if the zoom continuous shooting cancel signal is output due to disappearance of the release signal during zoom continuous shooting, for example, the zoom continuous shooting is stopped. For example, by releasing the user's hand from the release operating member, the photographer can stop zoom continuous shooting at his or her will, thereby preventing unwanted photos from being taken. At this time, the zoom continuous shooting mode setting is still maintained, so when the release signal is output again, zoom continuous shooting can be performed from the first frame or from the next frame where it was interrupted previously.
Improved usability.
