Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an imaging device, and particularly to an imaging device that uses a camera or the like to capture negative images (
It is suitable for use in film photographing devices that photograph positive (positive) film and the like.

(Background technology) In recent years, in the field of cameras, still video cameras (
Electronic cameras such as SV cameras (hereinafter referred to as SV cameras) have become rapidly popular, making it possible to record captured image information on magnetic recording media such as video floppies without the need for processing such as development as with silver halide cameras. It is characterized by the ability to immediately reproduce photographed image information on a television monitor, etc., and is becoming popular in all fields.

The specifications of this type of S camera include a fixed-focus photographic lens, an external viewfinder, a built-in strobe, and a close-up function. It's convenient.

In addition, since the Sv camera can immediately play back the captured image information on a display such as a television monitor, it is widely used in various presentations instead of conventional slides due to its convenience and ease of operation. It is being

By the way, since conventional slides use positive film, it is extremely troublesome to create film for slides because it is necessary to take pictures using positive film in advance or convert negative film to positive film. It is.

In this regard, it seems possible to solve these operability problems by using a video camera, performing image processing using electrical signals, and displaying the image on a monitor display or the like.

The S2 left camera, which records still images on a video floppy and plays them back, has a high possibility of being applied to such applications.

However, current SV cameras cannot be applied to such applications, and although devices that capture film images and output them to a monitor display have been proposed, they are limited to large-scale, dedicated devices. It is desired to develop a device that allows film photography to be easily performed using the S left camera.

Therefore, in order to enable negative and positive film photography using the Sv camera as is, the applicant has here developed an adapter-type film photography device that can be connected to the Sv camera to make film photography possible. The following problems arise in terms of film positioning.

(Problem to be Solved by the Invention) In other words, when shooting a film, there are two types of film: one shot horizontally and one shot vertically. When doing
Television monitors are compatible with images taken in a horizontal position, and when photographing images taken in a vertical position, the film must be rotated 90 degrees. However, making the mounting table on which the film or the member holding the film is mounted rotatable increases the size of the device, complicates the structure, and is disadvantageous in terms of cost. Furthermore, since the number of movable parts increases, the positional accuracy between the photographing lens and the film surface is also adversely affected.

This deterioration in positional accuracy causes blurring of focus, especially in close-up photography with a shallow depth of field.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and is characterized by: A device,
a film mounting section that holds the film within an imaging area; a film guide means that allows the film to be inserted onto the film mounting section from two directions orthogonal to each other; and a film guide means that allows the film to be inserted into the film mounting section. positioning means consisting of a plurality of pressing parts for pressing and positioning the film brought upward onto the film mounting part, and the pressing part is configured to press a plurality of pressing parts outside the imaging area on a diagonal line of the imaging area. There is an image pickup device configured as shown in FIG.

(Function) As a result, the film can be inserted into the film shooting position in the film photographing device from either the horizontal or vertical direction, and the means for regulating the position by pressing the film against the film mounting surface can also be used for shooting. The positioning action can be performed at a position that does not get in the way of the film, and at the same position regardless of the film insertion direction.
It becomes possible to take good pictures regardless of the horizontal orientation of the film.

(Example) The imaging device according to the present invention will be described below with reference to each figure.
A system consisting of a still video camera and a film adapter that enables film photography by attaching the still video camera will be described in detail as an example.

1 and 2 are a front view and a top view, respectively, of a still video camera.

In the figure, reference numeral 1 denotes a still video camera body (hereinafter referred to as the camera body), which photoelectrically converts the photographed image using an image sensor such as a COD and converts it into a video signal. It is to be recorded on the same track.

2 is a photographing lens; 3 is a photometric sensor window for measuring the brightness of the subject and controlling exposure; 4 is a finder optical system;
5 is a strobe light emitting window, 6 is a release button arranged on the top of the camera, 7L and 7R are left and right holding grips, 8 is a display section that displays various camera operation modes and control information, 9 is a track feed switch , various operation switches including a camera mode changeover switch, a strobe switch, a date input switch, etc. 10 is a macro photography changeover switch.

When shooting, use the left and right grips 7L and 7R of the camera.
The camera is configured to hold the camera grip 7R and operate the release switch 6 with the hand that holds the camera grip 7R to perform a photographing operation.

Although the details will be described later, the camera body is equipped with a negative/positive inverting circuit that inverts the negative/positive when recording captured image information. Controlled by a negative/positive switch on the side.

FIG. 3 is a perspective view of the film photographing adapter device according to the present invention in a usage state, and FIGS. 4 and 5 are a front view and a side view, respectively, for explaining the internal structure of the film photographing device according to the present invention. be.

In FIG. 3, 2o is the main body of the film photography adapter device, 21a and 21b are film insertion slits for inserting the film F to be photographed into the film photography adapter device, and these film insertion slits are the third slits.
In the figure, arrow a.

As shown in b, the film is configured so that the film can be inserted from two directions orthogonal to each other. A film mounting surface 20a is formed from these slits toward the inside of the device, and a photographing area is set at a position where these slits intersect.

Although the film F may be inserted directly through the film insertion slit, it is preferable to handle it while being stored in the film holder FH from the viewpoint of protecting the film and ensuring accurate positioning.

The reason why film F can be inserted from two orthogonal directions is that it is possible to insert film F from two orthogonal directions, regardless of whether the film is shot in a normal horizontal position or vertically. This is to enable recording on the recording medium in the vertical and horizontal positional relationship.

Reference numeral 22 denotes a camera holder section for holding the camera relative to the film photographing device 20, which has an opening for mounting the camera at the top and a space approximately the same shape as the front part of the camera body. When the camera is attached, the camera body is held so that the photographic lens optical system 2 is accurately positioned at a predetermined close-up distance with respect to the film surface. This camera holder is also used as a light shielding member to shield the space between the film and the camera's photographing lens optical system from external light to prevent unnecessary light from entering from outside when photographing the film on the film mounting surface. It has the following functions.

The camera holder 22 is also provided with a fixing screw 28 for accurately fixing the camera in the mounting position when the camera is mounted. An opening 23 for confirmation is formed.

The reason why the film at the photographing position on the film mounting surface is configured to be directly viewed through the opening 23 is as follows.

In other words, when the camera is attached to a film photographing device, the photographing lens is positioned exactly opposite the film, so in a camera that uses an external finder optical system, the finder is positioned offset from the film plane in the photographing area. At close range, such as when shooting with film, it is almost impossible to see the shooting area. Therefore, in order to view the film mounting surface using the camera's finder, it is necessary to introduce light from the photographing area into the finder optical system using optical path correction means such as refraction with a prism or reflection with a mirror. .

However, when optical path correction means using a prism is used, a difference occurs in the optical path length until the light reaches the finder at both ends of the object. This difference in optical path length is not so much of a problem when the subject is far away, but at close distances (for example, less than l0C11) as in film photography, it causes a difference in diopter, and when the subject is viewed through the finder, This causes a problem where part of the subject is out of focus.

Furthermore, the magnification of the finder also varies depending on the position within the photographing area, resulting in distortion of the finder image.

Furthermore, the method using mirrors requires at least two mirrors, one of which must be placed in front of the finder and the other in front of the photographic lens. In this case, the mirror in front of the photographic lens must be a half mirror, or it must be retracted into the photographic range during photographing, which complicates the mechanism and is disadvantageous in terms of both cost and space.

In order to solve these problems, in the present invention, the camera holder 22 is provided with an opening 23 through which the film surface can be viewed directly.

In addition, by doing this, you do not have to use the viewfinder on the camera side, which reduces the chances of touching the camera side, which is effective in preventing camera shake.Furthermore, the opening 23 and the various operation switches of the film shooting device are This is also effective in preventing erroneous operations since both can be visually checked at the same time.

Further, on the front surface below the opening 23, various operation switches are arranged.

24 is a release switch; 25 is an erase switch for canceling the photographed image; 26 is a negative/positive changeover switch for switching between negative and positive according to the type of film to be photographed;
7 is a display unit such as an LED that displays the operating state, and 29 is a power switch.

The electrical connection with the camera body will be discussed later, but
By turning on the power switch 29, the film shooting mode is automatically set, and by operating the release switch 24 on the film shooting adapter device side, a film image in the shooting area is recorded.

In other words, by attaching the camera to a film photographing device and making the necessary wiring connections, the release switch on the camera side is disabled, and the release switch on the film photographing device, which has a high degree of installation stability, can be used to release film images without directly touching the camera. This allows stable shooting with less chance of camera shake.

In addition, the erase switch 26 is used to erase a recorded image by operating it in a so-called rec-review operation state in which the recorded image is immediately played back on the camera side. You can check the recording status and choose whether to cancel it or leave it as a recorded image.

Next, the internal structure of the film photographing adapter device will be explained using FIGS. 4 and 5.

In each figure, the overall structure of the film shooting adapter device 20 is such that a camera holder 22 for holding a camera is arranged on the upper part of a film mounting surface 20a formed by extending into film insertion slits 21a and 21b, and a camera holder 22 for holding a camera is arranged on the lower part. A light source is arranged to illuminate the film from below.

The camera is mounted in the camera holder 22 with its front facing down, and the camera body l is positioned by the engagement of the positioning protrusions 22a and 22a with the engagement holes 1a and la on the bottom of the camera, and the fixing screw 28 is inserted into the camera holder 22. It is fixed at that position by screwing into the screw hole 1b on the camera side.

11 is a CCD placed behind the optical system of the photographing lens in the camera, which photoelectrically converts the formed image and presses the imaging signal.
12 is a photometric lens that focuses the light incident through the photometric sensor window 3 onto a photometric sensor (SPC) 13.

Looking inside the camera holder 22, a close-up optical system 30 consisting of a close-up lens 32 attached to a lens barrel 31 is located at a position opposite to the photographing lens optical system 2 of the camera, and a close-up optical system 30 is located at a position opposite to the photometric sensor window 3. The photometric correction optical system 33 includes a prism 34 for correcting the optical path in order to introduce light in the photographing area into the photometric sensor window 3, and a photometric correction member 35 for correcting the photometric light amount distribution.
are supported via support members 36, respectively. Detailed functions will be described later.

Further, on the upper surface of the support member 36 facing the front surface of the camera, there are elastic members 36a and 36b made of rubber etc. for temporarily positioning the camera to be mounted on the camera holder 22 at a position where the fixing screw 28 near the mounting position can be screwed. It also functions as a cushioning member when the camera is attached.

On the other hand, on the surface opposite to the film mounting surface in the vicinity of the opening 38 of the upper plate 20b of the film photographing adapter device 20 to which the camera holder 22 is attached, there is a film F or a film holder inserted through the film insertion slits 21a and 21b. A film holding member 37 is arranged to position the FH for each frame and to elastically press the film onto the film mounting surface to suppress lifting and keep the photographing distance constant.

The film holding member 37 is a leaf spring-like elastic member that is integrally molded when the upper plate 20b of the apparatus is molded, and a substantially conical engagement protrusion 37a is formed in the portion that comes into contact with the film or the film holder. does not interfere with insertion.

Also, as is clear from FIG. 9, which shows the photographing area from the camera insertion direction, the film pressing position is
These are set at two locations outside the shooting range of the film and on the diagonal lines of the shooting area, so that the film can be shot from two directions without damaging the film screen, and can be used for vertical and horizontal shooting, i.e., depending on the orientation of the image. In any case when inserted, the position can be regulated by pressing two diagonal points outside the photographing range, and the film holding effect can be obtained with the minimum pressing point.

In addition, in FIG. 9, 20c to 20c are indicated by arrows a and b.
This is a guide member that restricts the moving path of the film holder FH inserted from two directions.

Further, below the film mounting surface of the film photographing device 20,
Illumination section 4o for transmitting and illuminating the film from below
are arranged.

In FIGS. 4 and 5, 41 is the film mounting surface 20a.
42 is a fluorescent lamp as an illumination light source; 43 is a box-shaped reflecting plate for reflecting the light emitted from the fluorescent lamp and condensing it onto the film above; 44 is a light source, that is, a fluorescent lamp 42; a correction sheet for uniformizing the luminance distribution due to the light emission; 45 is a diffusion plate that diffuses the light emission from the light source;
The uniform light emitted from the light source illuminates the film from below through the opening 46 on the film mounting surface, and the transmitted light passes through the close-up lens 32 to the photographing lens 2 of the camera body 1. It is incident.

Further, 47 is a circuit board on which an electric circuit of the film photographing device is formed, 48 is an inverter circuit for lighting the fluorescent lamp 42, and 49 is a cable for connection with external connection equipment.

The configuration of the film photographing adapter device is as described above, and the functions of its close-up photographing optical system and photometry optical system will now be explained.

An image obtained by photographing a film image within the photographing area enters the camera-side photographing lens 2 through the opening 38 on the bottom surface of the camera holder 22 and the close-up lens 32 on the optical path indicated by L1 in the figure, and then enters the image sensor 11. was introduced, making it possible to take close-up shots of film images.

On the other hand, the film image is optically corrected by an optical path correcting prism 34 and guided to the photometric sensor window 3 along the optical path indicated by L2 in the figure, condensed through the photometric lens 12, and incident on the photometric sensor (SPC) 13. be done. This enables photometry of the photographic area.

By the way, to show actual data, in this example, the distance between the close-up lens and the film is approximately 36 m, and the distance between the optical axis of the photographing lens 2 and the optical axis of the photometric lens 12 is approximately 281 m.
1II11, and in this case, when looking at the light from the film shooting area that enters the photometric sensor 13, as is clear from FIG. 4, the optical path length from the center of the film surface of the shooting area is The optical path lengths are different. In this example, when calculated from the above distance data, the optical path length at the left end is approximately 10% shorter (and conversely, the optical path length at the right end is approximately 10% longer) than the optical path length at the center. illuminance)
is inversely proportional to the square of the distance, so the photometric sensor (SPC) 1
The brightness of the light on 3 is about 20% stronger at the left end and about 20% weaker at the right end compared to the center.

FIG. 6 is a diagram showing the relationship between the position on the film screen and its brightness level, that is, the output voltage of the photometric sensor.

As a result, when the subject, that is, the film image, has uniform brightness, the eight voltages of the photometer (sensor) 13 should normally be as shown by the - dotted chain line in Figure 6(a), but are shown by the solid line. As in, it becomes stronger on the left and weaker on the right.

If this continues, even if a film with a similar screen is bright, if the left side of the screen is bright, it will feel brighter than it actually is, so the brightness will be suppressed and the overall image will be dark. Conversely, if you shoot a film that is bright on the right side of the screen, it will appear darker than the actual brightness, and the shot screen will have overexposure and an overall white spot.Therefore, the left and right sides of the film image will be If the brightness distribution is uneven, the overall exposure will be distorted.

In order to correct such a difference in photometric sensitivity between the left and right sides, a light amount correction member 35 is provided to limit the light on the left side, which has a short optical path length and is detected brightly, with respect to the film screen that enters the prism 34 for optical path correction. ing.

This suppresses the emphasis on the left side, and the brightness distribution on the screen when photometrically measuring a uniform brightness surface, that is, the photometric sensor output, becomes as shown by the solid line in FIG. 6(b). In this state, the center will feel brighter than the left and right sides, but there will be no difference between the left and right sides, and the screen will look natural.

The light amount correction plate 35 is a rectangular plate-like member that blocks light, but if necessary, a transparent member may be used for the light amount correction plate 35 to perform subtle light amount correction by changing its transmittance. be able to.

In the above-mentioned light amount correction member 35, right-symmetric photometric sensitivity characteristics were obtained by restricting the light on the left side of the photographing area where the optical path length is shortened, but by restricting the light over the entire photographing area, a more uniform photometric sensitivity characteristic was obtained. It is also possible to obtain photometric sensitivity characteristics.

FIG. 7 shows an example of this, in which instead of the light amount correction member 35 in FIG. A narrow opening 351° is formed. By using this, the amount of light on the left side is suppressed, and it is possible to obtain photometric sensitivity characteristics similar to those of the light amount correction plate 35 in FIG. 4, as shown by the broken line in FIG. 6(b).

Further, as shown in FIG. 8, a similar effect can be obtained by using a light quantity correction member 352 whose transmittance decreases from right to left.

Next, the system configuration including the electrical connection between the camera body and the film photographing device as well as other connected devices will be explained.

As a result, the connection relationships shown in FIGS. 10 and 11 are established, and power can be supplied to each of the camera body 1 and the film connection adapter device 20.

The operation status of various operation switches on the film shooting adapter device 20 side is controlled by the cover microcomputer 6 in the cover 60.
By turning on the power switch 29 in the film shooting adapter 20, the operating state is supplied to the camera microcomputer 601 by the interlocking switch 29°, and the camera microcomputer 101 is controlled by the command from the camera microcomputer 601. Thereafter, the film shooting mode is set in which the camera microcomputer 101 is controlled by operations on the film shooting adapter 20 side.
