DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic image pickup apparatus having display means for receiving an image signal from an electronic image pickup means for photoelectrically converting a subject image and generating an image signal and displaying an image, and a method for converting a subject image to silver. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for both silver halide photography and electronic imaging having both functions of a silver halide photography apparatus for exposing to a salt film, and which does not cause a difference in the angle of view between electronic imaging and silver halide photography.

[0002]

2. Description of the Related Art Conventionally, an image pickup means for converting a subject image formed by a photographing optical system into an electronic signal, and an image signal output from the image pickup means are recorded on a recording medium and represented by the image signal. An electronic image pickup apparatus having display means for displaying an image, and a silver halide photographing apparatus for exposing a subject image formed by a photographing optical system to a silver halide film. A large number of cameras for both silver halide photography and electronic imaging configured to execute an imaging operation by the electronic imaging device in conjunction with an exposure operation have been proposed.

[0003] This camera for both silver halide photography and electronic imaging is
It has the advantage that the same subject image as the latent image exposed on the silver halide film by the silver halide photographing device can be immediately confirmed on the image displayed on the display means by using the image signal captured and generated by the electronic imaging device. .

In this camera for both silver halide photography and electronic imaging, as disclosed in Japanese Patent Application Laid-Open No. 62-61036, a single-lens reflex camera format captures a subject image with a single photographing optical system. The captured subject image is guided to a pentaprism by a reflection mirror, and the subject image emitted from the pentaprism is divided by a half mirror and projected to a painter and an electronic image sensor. As a result, the subject image viewed through the viewfinder, the subject image projected on the electronic image sensor, and the subject image exposed to the silver halide film by mirror-up the reflection mirror have the same angle of view. However, the subject image projected on the electronic imaging device has a reduced light amount because it is split into two by the half mirror,
When an electronic image generated by an electronic image sensor has a low brightness value, or when the brightness value of a subject is electrically measured from the electronic image to set the aperture value and shutter speed of the photographing optical system. In addition, it is necessary to set correction data and the like in consideration of the amount of light attenuated by the half mirror, and there has been a problem that setting of a measurement unit of a subject luminance value is troublesome.

In place of the single-lens reflex camera type camera for both silver halide photography and electronic imaging, a twin-lens type silver halide photography / electronic imaging camera having different photographing optical systems for silver halide photography and electronic imaging has also been developed. Has been put to practical use. In this twin-lens camera, the light amount of the subject image exposed on the silver halide film and the light amount of the subject image projected on the electronic image sensor have substantially the same value, and the light amount of the subject projected on the electronic image sensor can be secured, and In addition, the aperture and shutter speed of the silver halide photographing optical system can be set without considering correction data and the like when measuring the luminance value of the subject image from the electronic image signal generated by the electronic image sensor. However, the binocular silver halide photographing and electronic imaging camera is provided with an imaging optical system that guides a subject image to an imaging unit that converts an electric signal of the electronic imaging device into an electric signal, and a silver halide film of the silver halide imaging device. The photographing optical system that guides the subject image is separated from the photographing optical system, and is arranged in the camera body. Parallax occurs in which the photographing range of the photographing optical system and the photographing optical system deviates depending on the distance between the camera body and the subject.

Due to this parallax, erroneous recognition occurs when the photographing range of the latent image exposed on the silver halide film by the silver halide photographing device is confirmed in the range of the image displayed on the display means of the electronic imaging device.

Japanese Patent Application Laid-Open No. H10-107605 discloses a silver halide photographing and electronic imaging camera having an electronic image pickup device for displaying an image in the same photographing range as the photographing range of the latent image exposed on the silver halide film by the silver halide photographing device. No. 104736 is proposed.

The camera for both silver halide photography and electronic imaging proposed in Japanese Patent Application Laid-Open No. 10-104736 discloses a camera which uses an electronic imaging device to mask an area of a subject image exposed on a silver halide film by the silver halide photography device. A subject exposed to a silver halide film by the silver halide photographing device, out of the image signal of the subject imaged or generated by the electronic imaging device, or superimposed on an image of the captured and generated subject image or displayed on a display unit. The image signal is enlarged and displayed on the display means using the image signal in the same photographing range as the image.

A subject image having an angle of view between 7 and the lower limit ray 208 is formed on the silver halide film 202.

On the other hand, a subject image captured by the electronic image pickup lens 204 is an image between an upper limit light ray 210 and a lower limit light ray 211 based on a principal ray 209 connecting the electronic image pickup lens 204 and the center point of the electronic image pickup element 205. A subject image at the corner is formed on the electronic imaging element 205.

The principal ray 206 for the silver halide photography and the principal ray 209 for the electronic imaging are arranged on the object plane 21 at a predetermined finite distance.
2, the distance between the subject plane 212 and the silver edge photographing lens 201 is several meters. Accordingly, the angle of view of the subject image captured by the silver halide photographing lens 201 and the electronic imaging lens 204 and formed on the silver halide film 202 and the electronic imaging element 205 is the upper and lower limit light rays 207 and 208 of the silver halide photography and the electronic imaging. Lower ray 21
Shooting angle of view 2 on subject plane 212 where 0 and 211 match
13 is set.

In a camera in which the angle of view of the subject in silver halide photography and electronic imaging is set to coincide at a predetermined finite distance, the camera body 200 and the subject are brought closest to each other.
At the time of macro photography in which a subject on the subject plane 214 in the drawing is photographed, the angle of view of the subject in silver halide photography is limited to the upper and lower limit rays 20.
The subject 215 in the range of 7,208 is the silver halide film 202
The object angle of view of the electronic imaging is the object angle of view in which the object 216 in the range of the upper and lower rays 210 and 211 is imaged on the electronic image sensor 205. The subject 215 for photographing and the subject 216 for electronic imaging do not match.

That is, by using the above-mentioned twin-lens camera for both silver halide photography and electronic imaging, the subject and the camera

Becomes That is, during macro photography and infinity photography with the twin-lens silver halide photography and electronic imaging camera, the electronic imaging subject angle of view shifts upward and downward with respect to the silver halide photography object angle of view due to parallax. Would be.

As disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 10-104736, a mask is applied to such a parallax with respect to the angle of view of an electronic imaging subject, based on electronic image processing, or In order to enlarge the image, as shown in FIG.

[0017]

In the above-described twin-lens type camera for photographing silver halide and electronic images, parallax occurs between the silver halide photographing optical system and the electronic imaging optical system. In Japanese Patent Application Laid-Open No. 10-104736, the parallax is electronically corrected so that the object angle of view of the silver halide photography and that of the electronic imaging coincide with each other. However, in a camera having a shortest shooting distance, even if electronic parallax correction is performed, the electronic imaging device needs to have a wide range of object imaging surfaces. Generally, the subject image-forming surface of the electronic image sensor and the photoelectrically convertible region have an aspect ratio of 4: 3.
In order to correct parallax by electronic processing, it is necessary to use an electronic image sensor having a special aspect ratio having a wide range of image forming surfaces of a subject. For this reason, a general-purpose aspect ratio electronic imaging device cannot be used,
The use of the electronic image pickup device having a special aspect ratio has a problem that the miniaturization of the electronic image pickup device is hindered, and the cost increases due to the use of the special electronic image pickup device.

According to the present invention, there is provided a silver salt capable of miniaturizing and reducing the cost of an electronic imaging device and minimizing the occurrence of parallax by using a general-purpose aspect ratio electronic imaging device. It is an object of the present invention to provide a camera device for both photographing and electronic imaging.

Aperture mechanism 22
And so on. This silver halide photographing optical system 11
Is a so-called zoom lens capable of performing a zooming operation for continuously changing the focal length.

The positive lens 21 and the negative lens 23 are driven and controlled by a zoom / focus drive circuit 37, whereby a predetermined automatic focus adjustment operation (AF operation) and a predetermined zoom operation (zoom operation) are performed. ) Etc. are executed. The drive of the first aperture mechanism 22 is controlled by an aperture drive circuit 38. The control of the first aperture mechanism 22 for the exposure adjustment operation is performed as follows.
This is done by this.

A silver halide photographing optical system 11 including a positive lens 21 and a negative lens 23, a first aperture mechanism 22, and the like,
Electric circuits such as the zoom / focus drive circuit 37 and the aperture drive circuit 38 are arranged at predetermined positions inside a first lens barrel (not shown) as a holding member for holding these circuits.

In the zoom / focus drive circuit 37, a drive source such as a general electromagnetic motor or an ultrasonic motor, a driver circuit for controlling the drive source, the positive lens 21, the negative lens 23, and the like are moved. In this case, a predetermined signal is generated in accordance with the condition (1), thereby including an encoder device and the like for detecting the position of each lens (detailed illustration is omitted).

The optical axis 0 behind the silver halide photographing optical system 11
A movable mirror 24 having a substantially central portion formed by a half mirror or the like and having one end rotatably supported by an internal fixing member (not shown) of the camera is disposed at a predetermined position on the camera 1. ing. The movable mirror 24 is inclined at a predetermined angle, for example, approximately 45 degrees with respect to the optical axis 01 of the silver halide photographing optical system 11 in a state where the photographing operation is not being performed (referred to as a photographing preparation state). The reflecting surface is arranged so as to face the silver halide photographing optical system 11 (subject side) and upward.

A mirror drive circuit 39 is electrically connected to the movable mirror 24. The mirror drive circuit 39 receives a predetermined control signal from the CPU 48 and controls the drive of the movable mirror 24. It has become. That is, the movable mirror 24 and the mirror driving circuit 39 constitute a so-called quick return mechanism.

Therefore, when the camera is in a photographing preparation state, a part of the subject light flux transmitted through the silver halide photographing optical system 11 is reflected upward by the reflecting surface of the movable mirror 24. Observation optical system (hereinafter, optical finder) arranged above movable mirror 24
It is led to the blocks that make up 30.

On the other hand, a sub-mirror 25 composed of a total reflection mirror is disposed at a substantially central portion on the back side of the movable mirror 24 so as to be rotatable with respect to the movable mirror 24. The sub-mirror 25 serves to reflect the subject light flux transmitted through the half mirror portion at the substantially central portion of the movable mirror 24 and guide it to a predetermined position below the sub-mirror 25.
The sub-mirror 25 is also connected to the mirror driving circuit 3 described above.
9 is driven and controlled.

Below the sub-mirror 25, at a predetermined position on the reflection optical axis of the sub-mirror 25, there is disposed a separator optical system 26 composed of two optical systems for separating the subject light beam into two images. I have. This separator optical system 2
A line sensor 27 is arranged at the image forming position of the subject image re-imaged by 6. This line sensor 27
, A line sensor drive circuit 40 is electrically connected, and the line sensor drive circuit 40 receives a predetermined control signal from the CPU 48 and controls the drive of the line sensor 27.

A focus detection device using a general phase difference detection method is constituted by these components, that is, the sub-mirror 25, the separator optical system 26, the line sensor 27, and the line sensor drive circuit 40. . In this case, the CPU 48 calculates the distance between the two images by the separator optical system 26 based on the signal input from the line sensor 27 via the line sensor drive circuit 40, and calculates the lens drive amount and the like when performing the focus adjustment operation. Is calculated. Information such as the drive amount calculated in this manner, that is, the lens drive amount calculated based on the output (integration result) from the line sensor 27 and the output from the encoder device (lens position information) and the like are transmitted via the CPU 48. Is transmitted to the zoom / focus drive circuit 37, whereby the lenses 21 and 23 of the silver halide photographing optical system 11 are driven to a desired position (focus point) to control the focus adjustment operation and at the same time perform the zooming operation. It can be done.

Behind the movable mirror 24, the amount of exposure (exposure time) of the luminous flux of the object to the light receiving surface of the film 29 when the silver halide film 29 (hereinafter simply referred to as film) is exposed is controlled. A shutter mechanism 28 is provided, and a film 29 is provided at a predetermined position immediately after the shutter mechanism 28 at a predetermined interval.

The shutter mechanism 28 is driven and controlled by a CPU 48 via a shutter drive circuit 41. For example, the movable mirror 24 is controlled by the mirror drive circuit 3
When the shutter mechanism 28 is turned to the retracted position from the optical axis 01 in the upward direction in the drawing by 9, the shutter mechanism 28 is simultaneously controlled by the shutter drive circuit 41 so as to be opened for a predetermined time. It has become. As a result, the light receiving surface of the film 29 is irradiated with almost all of the luminous flux transmitted through the silver halide photographing optical system 11, and a subject image formed thereby is formed on the film emulsion surface (light receiving surface).
Therefore, a predetermined exposure is performed on the film 29.

As a shutter constituting a part of the shutter mechanism 28, for example, a focal plane shutter or the like generally used in a conventional single-lens reflex camera or the like is applied. This focal plane shutter normally uses a biasing force of a biasing means charged prior to an exposure operation to set a front curtain and a rear curtain between one end and the other end of a shooting screen. At predetermined intervals. Regarding the configuration of the shutter mechanism 28, it is assumed that a focal plane shutter that has been generally practically used in the past is applied, and a detailed description thereof will be omitted.

The film 29 used in the camera
Is a rolled silver halide film for photography which is wound and stored in a film cartridge of a general form.
On a light receiving surface of the film 29, that is, on a back surface side of the emulsion surface, and in a predetermined region of the film 29, a magnetic recording layer or the like capable of magnetically recording various information is formed. A magnetic head (not shown) is arranged at a predetermined position on the camera side facing the magnetic recording layer so as to contact the magnetic recording layer.

This magnetic head is capable of magnetically recording various information in a predetermined area (magnetic recording layer) on the film 29, and includes a magnetic head drive circuit (not shown).
Drive control by the CPU 48 is performed via the.

Further, a film drive circuit 42 for controlling the film feeding operation is provided near the film 29 loaded inside the main body of the camera. The film driving circuit 42 is driven by a driving force transmitted through a film feeding mechanism (not shown) composed of a gear train or the like for feeding the film, for example, every time a shooting operation for one frame is completed. Then, drive control or the like for automatically winding the film 29 by a predetermined amount is performed, whereby an operation such as disposing the next frame (unexposed portion of the film) at a predetermined position inside the camera is performed. The above-mentioned magnetic recording operation of the predetermined information on the film 29 by the magnetic head is executed in conjunction with the winding operation of the film 29 by the film driving circuit 26 or the like.

On the other hand, above the movable mirror 24, on the optical path of a subject light beam (hereinafter also referred to as a finder light beam) reflected by the movable mirror 24, a subject image (hereinafter referred to as a finder light beam) to be formed by this finder light beam , Which is also referred to as an observation image), and a focusing plate (not shown) formed so that the focus state of the observation image can be confirmed, and an image conversion that performs image conversion so that the observation image can be observed as an erect image. A pentaprism that is not provided, and a finder eyepiece 17 that includes a lens that re-images the subject image converted into an erect erect image by the pentaprism are provided. These members, that is, the focusing screen, the pentaprism, and the finder eyepiece 17 constitute a block of the optical finder 30.

That is, in the camera of this embodiment,
As means for observing a subject image, in addition to a display means (LCD monitor 46) in an electronic imaging device to be described later, the optical finder 30 for observing an optically formed subject image (observation image) is also provided. It is set up.

In the present camera, the optical finder is provided separately from the display means for the following reason. That is, a conventional general silver halide camera usually includes an optical finder 30 as a means for confirming an observed image when taking a photograph.

Normally, when taking a picture,
If the camera slightly moves due to so-called camera shake during the shooting operation, a good image may not be obtained. Therefore, it is necessary to securely hold the camera during the execution of the photographing operation. In this case, when the optical viewfinder 30 is used, the camera is inevitably placed near the user's face (that is, the eyes). It will also be supported by part of the face. Therefore, when observing an observation image using the optical finder 30, the camera can be securely held to prevent camera shake and the like.

On the other hand, a conventional general electronic image pickup apparatus or the like is provided with display means such as a liquid crystal display for displaying an image for observation or displaying a photographed image prior to an image pickup operation. It is common to use as a finder. In order to observe an image displayed on this display device, it is usually necessary to separate the camera itself from the user's eyes by a certain distance. Therefore, in order to perform an imaging operation while confirming an observation image using this display means, the user must hold the camera with only both hands.
Therefore, in this case, the camera tends to be in an unstable state as compared with a case where a photograph is taken while observing an observation image using an optical finder, and problems such as camera shake often occur. It will be.

The rotation amount of the electric motor during the counterclockwise rotation of the strobe pop-up unit 14 is detected by the photointerrupter 93, and the rotation of the electric motor 91 is stopped when the strobe popup unit 14 reaches the macro shooting mode position. Then, as shown in FIG. 8C, the flash pop-up unit 14 is fixedly maintained at the macro shooting mode position by the urging force of the opening spring 65 and the spring material 90.
