Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera capable of confirming, from the side of a person who is a subject, whether or not he / she is within the field of view of the camera, for example, during self-timer photographing. It is a thing.

[0002]

2. Description of the Related Art In photographing using a self-timer, first, a predetermined delay time is set by using a self-charge lever or the like provided on the camera side, and thereafter, a person as a subject himself / herself performs a shutter release operation. After that, the camera moves to the shooting position to take a shooting pose, and shoots itself by the exposure operation of the shutter device that operates after a lapse of a predetermined delay time.

In this case, the person who is the subject confirms the progress of the delay time by checking the return state of the self-charge lever and the change of the light blinking speed of the dedicated operation display device.
It is usual to wait for the exposure operation to approach.

As for the self-timer display device or the operation display device for the camera used in such a case, for example, Japanese Patent Publication No. 59-52410 and Japanese Utility Model Publication No.
It has been already known from the publications such as 2-14438 and Japanese Utility Model Laid-Open No. 63-125836.

By the way, when taking a group photo with a large number of people as subjects such as a commemorative photo during a group trip, it is natural that all the group members are taken within a limited screen (angle of view). However, if this is done with self-timer shooting, the camera operator (secretary) has to make a great effort.

That is, in such a photography, the camera operator first selects a background, decides a shooting location, installs the camera, gathers all the groups at that location, and then looks into the viewfinder of the camera to see the background. While locating everyone except myself in the shooting screen while trying to harmonize with each other, the place where I am located is also decided with the viewfinder, and after all the work is decided, the self-charge lever is set and the shutter release operation is performed. After that, the work of moving to the planned alignment position and waiting for the exposure operation is performed.

On the other hand, when it is desired to take a large picture of a desired subject on a print screen, it is a general method to use a taking lens having a long focal length in advance to take a telephoto shot of the desired subject. Other methods can be used to achieve this goal.

For example, a target subject is photographed by using the normal photographing mode, and when printing at a film developing station, a portion of the photographed subject image is trimmed and only the trimmed portion is normally printed. The method of printing with a trimming magnification larger than the magnification can also achieve the purpose of enlarging the desired subject on the print screen.

In this case, the trimming magnification is projected in consideration of easiness of printing work at the film developing station even if the photographing frame printed at the normal printing magnification and the photographing frame printed at the trimming magnification are mixed. Usually, the magnification is set so that the common photographic paper can be printed by changing the magnification of the lens.

Therefore, in the case of photographing in accordance with such a photographic processing system, at least the trimming designation information (for example, the position of the trimming field and the trimming magnification) indicating that the photographing is performed in the trimming mode is performed, for example, optically or magnetically. It is preferable that the image is attached to the photographic frame on the film by a physical method.

[0011]

However, in the case of self-timer photographing, a large number of people are instructed by reciprocating between the alignment location and the camera to indicate their own positions, or by giving instructions to the group members while looking through the viewfinder. It's not easy to keep the group members in a limited screen.

Moreover, since the group member to be photographed does not actually look into the finder, the person located outside, for example, is always worried that "I am inside the screen?" It will make you feel.

In particular, in self-timer photographing using a compact zoom camera which has been widely used in recent years, it is not possible to confirm (predict) the situation of the focal length at that time from the change of the appearance of the camera, and to what extent. It becomes more difficult to know if is the shooting range, so that feeling becomes remarkable.

On the other hand, in the case of the trimming photographing in accordance with the above-described photo processing system, it is the self-timer photographing to judge whether the person to be photographed is in the field of view to be trimmed or not. Will be even more difficult.

As described above, in photographing using a conventional camera, when performing self-timer photographing or trimming photographing, from the side of the person standing at the position to be photographed, he or she is positioned inside the photographing visual field area. I was in a state where I couldn't know whether I was doing it.

However, a dedicated device capable of coping with such a situation is not yet known, and the self-timer display device or the operation display device of the camera described above is also a dedicated device for self-timer photographing. Even though it was provided as a device, it had become unusable in such a situation.

The present invention has been made in view of the above circumstances, and its purpose is not limited to self-timer photographing, trimming photographing and photographing by remote control, but a person who is a subject The object of the present invention is to provide a new camera that allows the user to always know that he is located in the shooting screen by directly visually recognizing the identification light beam from the shooting field identification means installed on the camera side. ..

[0018]

In order to achieve the above-mentioned object, the invention according to claim 1 has a structure in which only a predetermined photographing field area can be accommodated within its optical directional angle. It is characterized by including means.

Further, the invention according to claim 2 is provided with a variable focus type photographing lens and a variable field of view finder, and at least in connection with a focal length changing operation of the photographing lens or a viewfinder changing operation.

Further, the invention according to claim 4 is a trimming mode setting means capable of selectively changing the mode of the varifocal taking lens, the field of view finder and the camera from the varifocal taking mode to the trimming mode. And when the camera is set to variable focus shooting mode,

It is characterized in that the optical directional angle of the identification means is changed to a directional angle capable of accommodating only the trimming area set in advance in the photographing field area in the variable focus photographing mode.

According to a fifth aspect of the invention, there is provided setting means for selectively setting the camera mode from the normal photographing mode to the self-timer mode, and when the camera is set to the self-timer mode, It is characterized in that the photographing visual field identifying means can be operated only while the mode is set.

Further, the invention according to claim 6 is provided with remote operation means capable of remotely controlling the camera, and when a specific operation member provided on the remote operation means side is operated, only during the operation. It is characterized in that the photographing visual field identifying means can be operated.

[0024]

In the camera constructed as described above, the photographing field-of-view identifying means having a structure capable of containing only the planned photographing field-of-view area including the trimming area within the optical directivity angle is installed on the camera side, and the self-timer is provided. Not only in the case of shooting, trimming shooting, and shooting by remote control, but also during normal shooting, the person as the subject directly visually recognizes the identification light beam from the imaging visual field identification means at the position to be captured. By doing so, it is always possible to know for myself whether or not I am positioned within the shooting screen.

Each of 6 is configured to be connected to the overall control calculation unit CPU.

In FIG. 2, reference numeral 17 denotes a see-through finder provided in the camera 1, which has an appropriate finder optical system (not shown) for a single focal length.

Reference numeral 21 is a photographing visual field identifying means which constitutes a characteristic part of the present invention. For example, in self-timer photographing,
From the side of the person standing in the position to be photographed (hereinafter, referred to as “person who is the subject”), it is confirmed whether or not oneself is positioned inside the photographing visual field area S (angle of view θ ° of the photographing lens L). It is provided to make it possible.

In this case, according to the present invention, the photographing visual field identifying means 21 (1) projects an identifying light beam from the photographing visual field identifying means 21 toward the photographing visual field region S, and (2) the person as a subject has a photographing visual field. When the person is located inside the area S, (3) on the contrary, the person who is the subject has the photographic field of view S so that the person can see the identification light beam directly.
The object is achieved by constructing such a discriminating light ray so that it cannot be visually recognized when it is located outside the.

That is, in the first embodiment, as shown in the enlarged view of FIG. 3, the photographing visual field identifying means 21 is, for example, an appropriate holding case 22 attached to the front exterior wall member 1a of the camera 1, and the appropriate holding case 22. A light emitting member 23 formed of a light emitting element such as an LED element provided in the holding case 22.
And a hood member 25 having a field opening 25a for determining the field of light projected by the light projecting optical member 24.

In this case, in the first embodiment, the field opening 25a of the light projecting optical member 24 is arranged at a position horizontally deviated from the optical axis O of the taking lens L as shown in FIG. There is. Therefore, a parallax as shown in FIG. 4 occurs between the projection visual field formed by the optical directing angle α ° of the identification light beam emitted from the light emitting member 23 and the photographing visual field region S.

By the way, the photographing visual field discriminating means 21 must be constructed so that as long as the person as the subject is located in the photographing visual field region S, the discrimination light ray can be visually recognized directly from that position. If simply configured in this manner, the following problems will occur depending on the camera.

That is, for example, in a camera in which the closest shooting distance is set to 1 m, in order to make it possible to directly visually recognize the discriminating light beam from the shooting visual field area S regardless of the shooting distance, the shooting of 1 m is performed. At the distance position, one limit line of the identification light beam of the imaging visual field identification means 21 is made to coincide with one limit line of the angle of view θ ° of the taking lens L, and at the infinite distance position, the other limit line of the identification light beam is made. The limit line must be set so as to match the other limit line of the angle of view θ ° of the taking lens L.

However, when the value and the direction of the optical directivity angle α ° of the identification light beam are set under such conditions, the visible region of the identification light beam within the angle of view θ ° of the taking lens L is shown in FIG.
Since it is extremely narrow as shown by the shaded area and is greatly inclined with respect to the angle of view θ ° of the taking lens L, if a group of persons to be imaged relies on this identification ray to determine their respective positions, for example, At a position close to infinity, the composition is biased to one side as shown in FIG. 5, and at the closest shooting distance, the composition is biased to the other side.

Since this is a problem, in the illustrated embodiment, such a bias phenomenon does not occur in the shooting distance range (usually 2 m to 5 m) commonly used for self-timer shooting. There is.

That is, as shown in FIG. 6, the relationship between the projection visual field of the identification light beam formed by the optical directing angle α ° and the photographing visual field area S is shown in (a) the position of the closest distance of the camera ( For example, in 1 m), one limit line a ₁ of the identification light ray passes a point within the angle of view θ ° of the taking lens L, and the other limit line a ₂ of the other side of the angle of view θ ° of the taking lens L. Passing a point outside the limit line b ₂ ,

(B) At a position on the near side of the commonly used photographing distance (for example, 2 m), one limit line a of the identification light beam
₁ passes through a point within the angle of view θ of the taking lens L,
The other limit line a ₂ passes through the point where the other limit line b ₂ of the angle of view θ ° of the taking lens L coincides,

(C) At a position on the far side of the commonly used photographing distance (for example, 5 m), one limit line a of the identification light beam
₁ passes through a point that coincides with _one limit line b ₁ of the angle of view θ ° of the taking lens L, and the other limit line a ₂ passes through a point within the angle of view θ ° of the taking lens L,

(D) At the position at infinity, one limit line a ₁ of the identification light ray passes a point near the outside of _one limit line b ₁ of the angle of view θ ° of the taking lens L, and the other limit line a ₁ It is set so that the limit line a ₂ passes through a point within the angle of view θ ° of the taking lens L.

That is, in the illustrated embodiment, the focal length of the projection optical member 24 of the photographing visual field identification means 21, the hood member 2
The shape of the visual field aperture 25a of FIG.
Numerical values, shapes, and related positions that can realize a single projected field of view are set.

As a result, the projection visual field of the identification light ray 23 becomes slightly narrower than the current shooting visual field area S at all photographing distances, but the group of persons photographed at the usual photographing distance becomes this discrimination light ray. By relying on each position, a photograph with the proper composition as shown in FIG. 7 is obtained.

In the case of the first embodiment, assuming that a parallax in the horizontal direction exists between the photographing visual field identifying means 21 and the optical axis O, the angle of view θ ° of the photographing lens L and Although the directional relationship with the optical directivity angle α ° of the shooting visual field identification light beam is set, if there is a vertical parallax, it should be set according to the above-mentioned concept with the ground side as the reference. ..

Reference numeral 26 is a self (and remote control) display control unit which controls the light emission timing control of the light emitting member 23 and the time control at the time of flashing light emission, and is provided between the photographing visual field identification means 21 and the overall control calculation unit CPU. Has been.

The self-display control unit 26 sets the light emission and light emission stop timing of the photographing visual field identification means 21 at the end point of the second stage stroke operation of the shutter release member 13 subsequent to the ON operation of the self mode switch 16, for example. The light emitting member 23 is caused to emit light, and when the exposure operation of the shutter device 3 ends after the elapse of a predetermined delay time, the light emitting member 23 is controlled to stop the light emission. This is also the case when operating with a shutter release member on the remote control side, which will be described later.

That is, in the first embodiment, the flash light is emitted at the same time when the delay time in the self-timer photographing is started, and is turned off at the end of the exposure operation.

The light-emitting display of the light-emitting member 23 can be configured to be continuously turned on at the same time when the self-mode switch 16 is turned on. However, preferably, the degree of progress of the delay time is displayed to the person who is the subject. As can be notified, the flashing of the long interval is repeated at the beginning of the self-timer delay time, the flashing of a slightly narrow interval is repeated at the middle of the delay time, and the flashing of the extremely narrow interval is repeated at the end of the delay time. It shall be configured and placed.

Reference numeral 31 is an appropriate camera swinging means mounted on, for example, a tripod or a platform (both not shown), and a swinging control section 32 is detachably connected to the overall control calculation section CPU on the camera 1 side. It is configured to change the posture (horizontal rotation or elevation) based on a command from.

Reference numeral 41 denotes a remote control receiver used when the camera 1 is operated remotely, and is connected to the overall control calculation unit CPU.

Reference numeral 42 denotes a remote control transmission section prepared corresponding to the remote control reception section 41. When not in use, the remote control transmission section 42 can be detachably attached to an appropriate portion of the camera 1, for example.

Reference numeral 43 denotes a second photometric switch provided in the remote control transmission unit 42, which is turned on by a first-step stroke operation of a remote control side shutter release member (not shown) provided in the remote control transmission unit 42. Is configured.

Reference numeral 44 is a second release switch which is also provided in the remote control transmission unit 42 and is configured to be turned on by the second step stroke operation of the shutter release member on the remote control side. The second release switch 44 is also configured to double as a delay time start start switch.

Reference numeral 45 denotes a head swing operation switch also provided in the remote control transmitter 42, which is the head swing controller 32 described above.
The camera swinging means 31 can be remotely operated via the.

The CPU is an overall control calculation unit that controls the overall control of the camera 1, and is composed of an appropriate microcomputer, and controls the photographing sequence, the delay time formation control at the self-timer photographing, and the photographing visual field identification means 21. An arithmetic circuit, a memory circuit, a motor drive control circuit, etc. for performing various controls necessary for the camera 1 such as control of operation timing, attitude control for the camera swinging means 31, and remote control. (Not shown).

Next, the operation or action of the first embodiment thus constructed will be described by taking the case of self-timer photographing as an example.

The camera operator selects the self mode switch 1
When the shutter release member 13 is continuously pressed after operating the camera 6 to set the camera 1 to the self-timer shooting mode, the overall control calculation unit CPU sets the delay time at the self-timer shooting at the end of the operation. At the same time, the light emitting member 23 of the photographing visual field identification means 21 is caused to flash through the self-display controller 26.

After that, the camera operator selects a position where he / she stands in a region where the flashing light emission of the light emitting member 23 can be visually recognized while moving to the photographing position, and the interval of the flashing light emission of the light emitting member 23 becomes narrow. Wait for the moment when exposure of the shirt starts while confirming.

In this case, since the blinking light emission of the light emitting member 23 is within the visible region, it is always within the photographing visual field.
The camera operator, who is the subject, is always shown on the frame of the film F.

By the way, when blinking at a long interval is repeated at the beginning, blinking at a slightly narrow interval is repeated in the middle of the delay time, and blinking at an extremely narrow interval is repeated at the end of the delay time, when a predetermined delay time elapses, The overall control calculation unit CPU starts the operation of the active distance measuring unit 9 via the AF control unit 10 and the operation of the light measuring unit 12 via the photometric control unit 11, and subsequently the shutter control device 3 is activated. Control to operate.

Therefore, the focusing controller 2
Based on the distance measurement information from the F control unit 10, the photographing lens L is moved to the focusing position corresponding to the photographing distance at that time, and the shutter control unit 4 determines the appropriate EV value from the photometry control unit 11. The shutter device 3 is opened and closed.

When the exposure operation by the shutter device 3 is completed, the overall control calculation unit CPU drives the winding shaft 5 through the film feeding control means 8 to make the film F correspond to one frame of the photographing frame. The film is wound up by the feeding amount and is controlled to complete the shooting sequence related to this self-timer shooting. In this case, the film feeding detection means 7 detects the feeding amount of one frame of the film F and detects the film feeding control means 8.
Will be fed back to.

On the other hand, when the self-timer shooting is performed by remote control, the camera operator first operates the self-mode switch 16 to set the camera 1 in the self-timer shooting mode, and then sets the remote control transmitter 42. After the camera 1 is removed from an appropriate place, it is moved to a position where an image is taken, and the shutter release member on the remote controller side of the remote controller transmitter 42 is operated.

In this case, when the shutter release member on the remote controller side is operated, the second photometry switch 43 is turned on by the first step stroke operation, and the second release switch 44 is turned on by the subsequent second step stroke operation.
Each operation signal is transmitted from the remote control transmission unit 42.

The transmitted operation signals are received by the remote control receiver 41 on the camera 1 side and input to the overall control arithmetic unit CPU. Therefore, the overall control arithmetic unit CPU is similar to the above-described case. The self-timer photographing is performed by controlling each unit and each unit in 1 in the remote control mode.

By the way, the present invention is not an invention intended only for the convenience of self-timer photographing, but a person who is a subject determines whether or not he is located within the photographing visual field area. Therefore, the light emission timing of the photographing visual field identification means 21 described above can be set variously according to the design intention of the camera as well as the basic example described in the first embodiment. For example, (A) the first or second release switch 15 or 4
The light emitting member 23 is caused to emit light by 4 (all delay start start switches), and the light emission is stopped by the self-operation release operation represented by the re-operation of the self-mode switch 16.

(B) The light emitting member 23 is caused to emit light by the first operation of the self-mode switch 16, and the light emission is stopped by the self-operation releasing operation represented by the re-operation of the self-mode switch 16.

(C) The first or second release switch 15 or 44 or the self-mode switch 16 is first operated to cause the light emitting member 23 to emit light, and after a certain period of time has elapsed, the light emission is stopped.

(D) When the camera 1 is set to the self-timer photographing mode, the light emitting member 23 is caused to emit light by operating the first or second photometric switch 14 or 43.
The light emission is stopped by an appropriate operation or after a certain period of time.

(E) The light-emitting member 23 is caused to emit light by the operation of detaching the remote control transmitter 42 from the camera, and stopped by the operation of attaching it to the camera.

(F) The oscillating operation switch 45 is operated to cause the light emitting member 23 to emit light, and the light emission is stopped after a lapse of a predetermined time. It is possible to set such as. As for the light emission display of the imaging visual field identification means 21, either continuous light emission or blinking light emission can be adopted according to the design intention at that time.

This will be described with reference to 0.
