DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a film unit with a lens.

[0002]

2. Description of the Related Art A lens-equipped film unit in which an unexposed film is loaded at the time of manufacture in a unit body having a simple photographing mechanism such as a photographing lens, a shutter device, and a film winding device is sold. It has helped make it more accessible. Some film units with a lens have a built-in strobe that can be used at night or indoors, and are used by many users.

Various measures have been devised to improve the performance of these film units with lenses. In particular, it must cover all conditions, such as bright outdoor and indoor strobe shooting, without the exposure adjustment function. Also, because of the cost and compactness, only a small guide number strobe device can be used, so indoor shooting The problem of failed photos due to underexposure at the site has been noticed for some time. Japanese Patent Application Laid-Open No. 5-188454 discloses a measure for preventing underexposure by setting the EV value of the film unit to 11 or more and 13.5 or less, and setting the strobe guide number to 10 or more and 15 or less. Also, Japanese Patent Application Laid-Open No. 6-258787 discloses that a film unit with a lens incorporating a photosensitive material having a specific photographic sensitivity of 640 or more and a point gamma of 0.4 or more is satisfactory from indoor photography to outdoor photography. A method for providing a possible photograph is disclosed. Japanese Patent Application Laid-Open No. 8-184944 discloses a measure for preventing under-flash photography by a lens-equipped film unit having a shutter speed switching unit interlocked with a flash switching unit.

The present inventors have conducted intensive studies and found the following as a result of making photographs obtained by the film unit with lens more satisfactory. That is, the dissatisfaction when using the conventional lens-equipped film unit, particularly when using the strobe, is that the object for the unnatural finish of the photograph is larger than the underexposure.

This unnaturalness is caused by the fact that the background other than the main subject irradiated with the strobe is not captured at all and the surroundings are reproduced completely dark, and that the main subject itself has an excessively high contrast. I believe.

The present inventors have studied various measures such as the above-mentioned invention to be applied to a film unit with a lens, etc., and have independently studied a technique for loading a photographic film and a mechanism for a unit mechanism. However, they did not solve the problem and found a solution and found the present invention for the first time by devising both the photographic film and the mechanism of the unit. Also, in the process, increasing the strobe guide number, which has conventionally been considered preferable for preventing underexposure, rather exacerbates this problem, which is more important in many cases. He noticed and used this invention.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to solve these problems and to provide users with more satisfactory photographs by using a film unit with a lens.

More specifically, it is an object of the present invention to provide a lens-equipped film unit having an appropriate ratio between a main subject and a background and capable of obtaining a natural and high-quality photograph. Also,
It is an object of the present invention to provide a lens-equipped film unit that has appropriate contrast and can obtain a natural and high-quality photograph.

[0009]

In order to achieve the above object, when the shutter speed of the shutter device is T seconds, the aperture value of the aperture is A, and the ISO sensitivity of the photographic film is S,
After determining the film sensitivity, shutter speed, and aperture value that satisfy the conditional expression of “-6 ≦ 2 log ₂ (A) + log ₂ (1 / T) -log ₂ (0.3 × S) ≦ 5”, In the first embodiment of the lens-equipped film unit of the present invention, the photographic film is a layer having the highest sensitivity among the photosensitive layers having substantially the same color sensitivity,
It has at least one photosensitive silver halide emulsion layer containing a silver halide emulsion having an average grain size (diameter of a sphere having the same volume) of 1.0 μm or more and 3.0 μm or less.

Second Embodiment of Film Unit with Lens of the Present Invention
Wherein the photographic film has at least one photosensitive silver halide emulsion layer containing a silver halide emulsion having an average aspect ratio (diameter / thickness of a circle having the same area) of 5.0 or more. It was done.

Third Embodiment of Film Unit with Lens of the Present Invention
In the embodiment, the density function curve D (LogE) of the photographic film
The area where the point gamma (<γ> = dD / dLogE) is 0.4 or more is 2.8 or more in LogE.

The fourth aspect of the film unit with a lens according to the present invention.
In the embodiment, when the RMS value at the exposure amount at which the photographic film has the minimum density + d is RMS (d), “RMS (0.15) /
RMS (0.7) ≧ 1.2 ”.

In the film unit with lens of the present invention,
In addition to at least one of the requirements of the first, second, third and fourth aspects, a strobe unit is provided, and the strobe device can emit light with a guide number of 0.1 to 8 (ISO 100 · m). It is what it was.

Next, the present invention will be described in more detail.

First, the equation: 2 log ₂ (A) + log ₂ (1 / T) -lo
g ₂ (0.3 × S) (the shutter speed of the shutter device is T seconds, the aperture value of the aperture is A, the ISO of the photographic film is
The sensitivity was S). Hereinafter, in the present invention, the value represented by this equation is referred to as “system sensitivity”. The “system sensitivity” here is a value determined by the aperture, shutter speed, and film sensitivity. Naturally, this system sensitivity does not depend on the light amount of an auxiliary light emitting device such as a strobe or the distance to a subject. That is, to be precise, it should be called “system sensitivity without the auxiliary light emitting device”, and in fact, it is a number that is an index of how much brightness can be captured without a strobe.

Each term in the equation is known as AV (aperture value), TV (time value), SV (speed value), and system sensitivity = AV + TV-SV = 2 log ₂ (A) + log ₂ (1 / T) -log ₂ (0.3 × S). Note that A is an aperture value represented by a number such as 5.6, 8, or 11, and T is 1/60, 1/125, or 1 /.
Shutter speed represented by 250 (sec), S
Is I represented by a number such as 100, 400, 800, etc.
It is SO sensitivity, each APEX (additive system)
AV (aperture value), TV (time value) and SV (speed value) are represented by values according to the method of photographic exposure. As is apparent from the equation, when this value is reduced by 1, it means that the sensitivity is as high as possible even at a light amount of 撮 影.

In the present invention, the system sensitivity is -6 ≦ 2lo.
g ₂ (A) + log ₂ (1 / T) -log ₂ (0.3 × S) ≦ 5. By satisfying this conditional expression, appropriate background description is possible in most situations where the user wants to take a picture.

Preferably, -2≤2 log ₂ (A) + log ₂ (1 / T) -l
og ₂ (0.3 × S) ≦ 4, more preferably 1 ≦ 2 log ₂ (A) + log ₂ (1 / T) -log ₂ (0.3 × S) ≦ 3 It is.

The aperture value A, shutter speed T, and film sensitivity S may be any values as long as the above conditional expression is satisfied, but the aperture value A is preferably 4 ≦ A ≦ 11, and more preferably 4 ≦ A ≦ 11. 0.7 ≦ A ≦ 9.5, the shutter speed T is preferably 1/250 ≦ T ≦ 1/30, and more preferably,
1/125 ≦ T ≦ 1/45, film sensitivity is 400 ≦
S ≦ 6400, more preferably 1000 ≦ S ≦ 3200
It is.

It is desirable that the film unit with lens of the present invention be equipped with a mechanism for adjusting the exposure amount manually or automatically according to the aperture value or shutter speed. In that case, it is preferable that a shooting mode other than the conditional expression exists.

In order to satisfy a practically sufficient exposure latitude as a film unit with a lens, it is necessary to have a sufficiently long latitude as a color negative film, or to have an exposure control mechanism as a film unit with a lens. If possible, it is desirable to have both. In the film unit with a lens according to the present invention, it is desirable to secure a sufficient latitude by the above method. As an example of the latter, there is a method of interlocking a strobe switch and an aperture switch as shown in Japanese Utility Model Laid-Open No. 01-130118. It is also desirable that the shutter speed can be switched in conjunction with the strobe switch or as an independent switch.

The film unit with lens of the present invention includes:
It is desirable to use a strobe unit. The amount of strobe light depends on how many meters of the subject can be photographed, the aperture, the ISO sensitivity of the film, and the like. However, in the film unit with a lens of the present invention, the guide number is 0.1 to 8 (ISO 100 m It has been found that when light is emitted with the light amount of (1), an appropriate exposure is given to the main subject, and the probability that the density ratio of the subject background on the print becomes appropriate is high.

The guide number is preferably set to 0.
It is in the range of 1 to 6, more preferably 3 to
5 range.

Also, it has been found that when the guide number (GNo) satisfies the following relationship, appropriate exposure is possible.

It is more preferable that the relational expression of 8.0 ≦ log ₂ (GNo ² ) + log ₂ (1 / T) ≦ 10.0 is satisfied, more preferably, 7.0 ≦ log ₂ (GNo ² ) + log ₂ (1 / T) ≦ 12.0. (Where T represents a shutter speed (second)).

Next, the photographic film (hereinafter, also referred to as a light-sensitive material or light-sensitive material) used in the present invention will be described.

The photosensitive material used in the present invention may have at least one photosensitive layer provided on a support. A typical example is a plurality of (preferably two or more, more preferably two to four) silver halide emulsion layers having substantially the same color sensitivity but different sensitivities on a support. A silver halide photographic material having at least one photosensitive layer comprising

In the case of an ordinary silver halide color light-sensitive material, at least one or more light-sensitive layers having color sensitivity to blue light, green light and red light are provided. Further, in the case of a silver halide photographic light-sensitive material that forms a monotone dye image by performing color development processing, or in the case of a silver halide photographic light-sensitive material that forms a silver image by performing black-and-white development processing, at least one layer is used. A photosensitive layer having color sensitivity to the entire visible light is provided. Non-photosensitive layers may be provided between the silver halide light-sensitive layers and as the uppermost layer and the lowermost layer.

The average grain size of the silver halide emulsion contained in the light-sensitive material according to the first embodiment of the present invention will be described.

The particle size can be measured by a conventional method.
The average particle size is an average value of the particle sizes of 500 or more particles measured by an ordinary method. The silver halide grains in the silver halide emulsion include those having regular crystals such as cubic, octahedral and tetradecahedral, and those having irregular crystal forms such as spherical and plate-like. However, the grain size referred to in the present invention is expressed as the diameter of a sphere having the same volume as each silver halide grain. When the size of the cube is represented by its side length, the size of the flat plate may be represented by the diameter of a circle having the same area, etc.

The light-sensitive material used in the present invention is preferably a layer having the highest sensitivity among the light-sensitive layers having substantially the same color sensitivity, and more preferably a layer having a red, green and blue color. In the most sensitive layer, the average particle size is 1.0 μm
As described above, it is desirable to have at least one photosensitive silver halide emulsion layer containing a silver halide emulsion of 3.0 μm or less. The average particle size is more preferably 1.1
It is not less than μm and not more than 2.2 μm.

The inventor of the present invention determined this preferred particle size range by experimentally producing several film units with lenses and trial and error. The reason why this range is preferred is unknown at this time. In general, it is known that as the grain size of silver halide increases, the sensitivity of the photosensitive material increases, but the image quality deteriorates. On the other hand, it is also known that in a film unit with a lens that does not have a focus adjustment function, the image quality obtained by increasing the depth of field by increasing the sensitivity of the photosensitive material as much as possible and increasing the aperture value is also known. ing. 1.0 μm or more, 3.0 μm
It is presumed that the following means that, as long as the image quality as a photosensitive material is acceptable, the higher the sensitivity, the higher the image quality as a whole with the lens-equipped film unit.

The average aspect ratio of the silver halide emulsion contained in the light-sensitive material according to the second embodiment of the present invention will be described.

The average aspect ratio mentioned here has exactly the same definition as that usually used in the art. That is, the value obtained by dividing the diameter (equivalent circle diameter) of a circle having the same area as the principal plane (the plane having the largest area; in most cases, two parallel (111) planes having substantially equal areas) by the thickness of the particle. , The aspect ratio of the particles, and the average aspect ratio is 50
It is a simple average value of the aspect ratio of each of zero or more particles.

The light-sensitive material used in the present invention preferably has at least one light-sensitive silver halide emulsion layer containing a silver halide emulsion having an average aspect ratio of 5.0 or more. More preferably, the average aspect ratio is
It is 8.0 or more and 30.0 or less.

Any layer may contain a silver halide emulsion having an average aspect ratio of 5.0 or more. In the present invention, a specific layer is not particularly conceived as a layer containing an emulsion having a high aspect ratio, but the inclusion of the emulsion having a high aspect ratio in a layer far from the support can reduce the sharpness of the obtained image. Is preferable and preferable. It is also preferable that all the emulsions are silver halide emulsions having an aspect ratio of 5.0 or more.

The present inventor has found that the system sensitivity is -6 ≦ 2 log ₂
(A) + log ₂ (1 / T) -log ₂ (0.3 × S) During trial production of a film unit with lens that falls within the range of 5, natural sensitivity can be obtained with this system sensitivity. I noticed that some muddy sleepy photos were mixed. As a result of intensive studies, the present inventors have found that a natural and high-quality photograph can be obtained by incorporating a silver halide emulsion having an average aspect ratio of 5.0 or more into a photographic film to be used, and have accomplished the present invention.

Next, the point gamma of the silver halide emulsion contained in the light-sensitive material according to the third embodiment of the present invention will be described.

Point gamma <γ used in the present invention
> Means a value calculated using the density function curve D (LogE) (so-called characteristic curve) according to the following equation.

<Γ> = dD / dLogE The meaning of this expression is, for example, the Theory of the
Photographic Process (4th edition), page 502 (Macmilla
n Pub. Co., Inc., New York, 1977).

In the photographic film used in the present invention, the region where the point gamma <γ> is 0.4 or more is LogE2.
It is desirable that the number be 8 or more. Preferably, 3.0 or more,
More preferably, it is 3.2 or more.

The upper limit of the region where the point gamma is 0.4 or more is determined by an increase in film thickness and an increase in cost due to an increase in the amount of emulsion coating required for that purpose. Since it depends on various factors of the photographic film, it cannot be uniquely determined, but is usually preferably 4.0 or less.

The point gamma in this area must be 0.4 or more. Preferably, the point gamma is 0.5 or more and 1.0 or less.

When the photographic film used in the present invention is an ordinary silver halide color light-sensitive material, the three colors of blue, green and red are used.
It is desirable that at least one of the density function curves D (LogE) of the species has a point gamma of 0.4 or more and a LogE of 2.8 or more. Preferably, blue, green,
All red, the area where point gamma is 0.4 or more is Lo
gE is 2.8 or more. In the case of a silver halide photographic light-sensitive material that forms a monotone dye image by performing color development processing, or in the case of a silver halide photographic light-sensitive material that forms a silver image by performing black-and-white development processing, the target density function is used. There is only one type of curve D (LogE), and the point gamma is within the above range.

The present inventor has found that the system sensitivity is -6 ≦ 2 log ₂
(A) + log ₂ (1 / T) -log ₂ (0.3 × S) Prototype a film unit with a lens that falls within the range of ≤5, and perform various tests under various conditions, such as indoor shooting and outdoor shooting in fine weather. went. Among them, in order to maintain simple operability and low cost as a lens-equipped film unit, there is no exposure amount adjustment function, or assuming simple exposure switching, the point gamma of the photographic film to be used is as described above. It was found that if the relational expression was not satisfied, it would not be possible to satisfy a sufficient exposure latitude from a dark subject to a bright subject.

In particular, a preferred constitution intended in the present invention is that the point gamma of the photographic film used satisfies the above-mentioned relational expression,
As described in the reference, the exposure is switched by a simple method such as interlocking with a strobe switch.

Next, the R of the photographic film used in the present invention is
The MS value will be described.

The RMS value can be measured by a method well known in the art. That is, the change in the density value is represented by RMS (root mean square) by measuring the density of the developed portion to be measured with a constant exposure amount using a microdensitometer. In the present invention, the size of the aperture opening when measuring with a microdensitometer is 48 μm
The RMS value measured as × 48 μm is defined as the RMS value. The size of the aperture is not always defined in the industry. The aperture size that matches the visual granularity differs depending on the stretching magnification of the photographic film, the distance at the time of observation, and the like. 10 μm to 10
Although a size of about 0 μm is often used, the present invention employs an RMS measured at 48 μm.

The RMS value of a photographic film generally depends on the amount of exposure. In the present invention, the density function curve D (Log
In E), the RMS value at the exposure amount that gives a density (Dmin + d) larger by “d” than the minimum density (Dmin) is expressed as RMS (d).

The photographic film used in the present invention is RMS
It is desirable that (0.15) / RMS (0.7) ≧ 1.2. More preferably, RMS (0.15) / RMS (0.7) ≧ 1.35, and even more preferably, RMS (0.15) / RMS (0.7) ≧ 1.5. I don't think the upper limit of this equation needs to be considered, but in reality, RMS
(0.15) / RMS (0.7) is 5 or less.

When the photographic film used in the present invention is an ordinary silver halide color light-sensitive material, three colors of blue, green and red are used.
It is desirable that at least one of the species concentration function curves D (LogE) satisfies RMS (0.15) / RMS (0.7) ≧ 1.2. Preferably, blue, green and red are all RMS (0.15) / RMS
(0.7) ≧ 1.2. In the case of a silver halide photographic light-sensitive material that forms a monotone dye image by performing color development processing, or in the case of a silver halide photographic light-sensitive material that forms a silver image by performing black-and-white development processing, the target density function is used. There is only one type of curve D (LogE),
The RMS value is RMS (0.15) / RMS (0.7) ≧ 1.2.

In view of the above, it is preferable that the shutter speed T, the aperture value A, and the guide number GNo can be changed.

Next, the operation of the above configuration will be briefly described. In the photographic film 26b loaded in the film unit with an indoor lens, film information indicating the type used for the film unit with an indoor lens in the manufacturing stage is magnetically recorded on a magnetic data track.
The photographic film 26b on which the film information is recorded is loaded into the main body 20 together with the cartridge 26a. Then, the exposure unit 21, the strobe device 23, the front cover 24, and the rear cover 25 are assembled to the main body 20 to complete the unit main body 2. After the inspection, the label 3 is attached to the unit main body 2, and the film with the indoor lens is attached. The unit is completed. The completed indoor lens-fitted film unit is shipped and used for photographing by the user.

At the time of photographing, first, the winding knob 14
Is rotated to wind up the photo film 26b by one frame. Then, a shutter charge is performed in conjunction with the winding. Further, the photographer operates the operation lever 8 as necessary to select whether or not to use strobe light.

For example, when performing flash emission, the operation lever 8 is slid upward to the ON position. Then, the strobe switch 15 is turned on to start charging, and the strobe light emission is allowed. After confirming that the charging is completed, the display light guide 12 illuminates, the shutter button 10 is pressed.

When the shutter button 10 is pressed, the shutter device is operated, and the shutter blade 36 is opened and closed. At this time, when the shutter blade 36 is fully opened, the synchro switch 30 is turned on, and the strobe light is emitted. While the shutter blade 36 is open, the photographing light transmitted through the photographing lens 4 reaches the photographic film 26b via the aperture opening 41a, the shutter opening 38, and the aperture 20c, and the photographic film 26b is exposed. At this time, for example, when an image is taken indoors, a subject (main subject) located at a shooting distance of about 3 m has an illumination effect of strobe light, and is exposed using the strobe device 23 as a light source. The subject (background) farther than that has no illumination effect of the strobe light, and is exposed to the photographic film 26b using indoor lighting, for example, a fluorescent lamp as a light source.

In this way, shooting is performed for each shooting,
After the photographing of all the photographing frames is completed, the user rotates the winding knob 14 continuously to store all the photographic films 26b in the cartridge 26a. Then, the film unit with the lens is submitted to a developing laboratory or a DPE store.

The photosensitive material used in the present invention may have at least one photosensitive layer provided on a support. A typical example is a silver halide photographic light-sensitive material having at least one light-sensitive layer comprising a plurality of silver halide emulsion layers having substantially the same color sensitivity but different sensitivities on a support. It is. When the light-sensitive material used in the present invention is a color light-sensitive material, the light-sensitive layer is a unit light-sensitive layer having color sensitivity to any one of blue light, green light, and red light, and is a multilayer silver halide color photographic light-sensitive material. In the material, the arrangement of the unit photosensitive layers is generally arranged in the order of red-sensitive layer, green-sensitive layer, and blue-sensitive layer from the support side.
However, depending on the purpose, the order of installation may be reversed, or the order of installation may be such that different photosensitive layers are sandwiched between layers of the same color sensitivity. A non-light-sensitive layer may be provided between the silver halide light-sensitive layers and as the uppermost layer and the lowermost layer. These may contain a coupler, a DIR compound, a color mixing inhibitor and the like described below. The plurality of silver halide emulsion layers constituting each unit photosensitive layer are DE 1,121,470 or GB 92
As described in 3,045, it is preferred that two layers of a high-sensitivity emulsion layer and a low-sensitivity emulsion layer are arranged so that the sensitivity gradually decreases toward the support. Also, JP-A-57-112751,
As described in JP-A-62-200350, JP-A-62-206541 and JP-A-62-206543, a low-sensitivity emulsion layer may be provided on the side farther from the support and a high-sensitivity emulsion layer may be provided on the side closer to the support.

As a specific example, from the side farthest from the support,
Low sensitivity blue photosensitive layer (BL) / High sensitivity blue photosensitive layer (BH) / High sensitivity green photosensitive layer (GH) / Low sensitivity green photosensitive layer (GL) / High sensitivity red photosensitive layer (RH) / In the order of the low-sensitivity red photosensitive layer (RL), or in the order of BH / BL / GL / GH / RH / RL, or BH / BL / GH /
They can be installed in the order of GL / RL / RH.

As described in JP-B-55-34932, a blue-sensitive layer / GH /
They can be arranged in the order of RH / GL / RL. Also, JP-A-56
As described in -25738 and 62-63936, the layers may be arranged in the order of blue-sensitive layer / GL / RL / GH / RH from the side farthest from the support.

Further, as described in JP-B-49-15495, the upper layer is a silver halide emulsion layer having the highest sensitivity, the middle layer is a silver halide emulsion layer having a lower sensitivity, and the lower layer is a layer having a higher sensitivity than the middle layer. An example is an arrangement in which a silver halide emulsion layer having a low sensitivity is arranged and three layers having different sensitivities are sequentially reduced in sensitivity toward a support. Even when such a three-layer structure having different photosensitivity is used,
As described in JP-A-59-202464, in the same color-sensitive layer, the layers may be arranged in the order of medium-speed emulsion layer / high-speed emulsion layer / low-speed emulsion layer from the side away from the support. Further, in addition to the above three layers, a layer which gives a multilayer effect to the red-sensitive layer may be arranged as described in JP-A-61-34541.

In addition, high-speed emulsion layers / low-speed emulsion layers / medium-speed emulsion layers, or low-speed emulsion layers / medium-speed emulsion layers / high-speed emulsion layers may be arranged in this order.

Also, in the case of four or more layers, the arrangement may be changed as described above.
