Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a conventional photographing system, that is, a camera that can select the optimum photographing conditions in response to the photographing environment and photographic intention, by freely applying the selected photosensitive material. In contrast to conventional photographic systems that carry out planned and productive photographic processing based on predictions and concentrated opportunities, it is possible to easily and immediately respond to each photographic occasion by combining the camera function of light image formation and the photosensitive material function of receiving and recording images. Unexpectedly, by combining
The present invention relates to a photographing unit for use in a photographing system that performs made-to-order photographing processing on distributed occasions.

[Background of the invention]

In our daily lives, we sometimes come across scenes or materials that we need to photograph and record, but the camera we use to photograph them is not necessarily carried or prepared.
I sometimes miss photo opportunities. Furthermore, such missed opportunities are surprisingly common, and there is a potentially profound need for a photographing system that can easily and immediately respond to each photographic opportunity.

To meet this demand, we have already mobilized silver halide photosensitive material technology and resin lens and resin precision molding technology to ensure that we do not miss any photographic opportunities, even if we have to hand over the precise photographic finish to conventional photographic systems. It is now possible to construct a photographing system that can achieve the minimum photographic purpose.

Namely, the eyelids! Imitating the function of the eye, which is composed of the crystalline lens, vitreous body, and retina wrapped in a membrane, it has both camera and film functions; a photographic unit that can be called a "camera film" is already on the market, and a "disposable camera". ” etc. is commonly known as.

The above-mentioned photographing unit (camera film) is aimed at low cost, so there are many unsatisfactory points in the photographic finish, and there has been a growing demand for improvement.

[Problems to be solved]

An example of the configuration of a photographing unit that can generally function as a photographing unit is shown in FIG.

This figure is a cross-sectional view taken along a plane defined by the lens optical axis and a straight line in the film movement direction that intersects with the lens optical axis.

In the figure, l is a lens, 2 is a shutter, 3 is a silver halide photosensitive material (abbreviated as film), 4 is a photographing unit, 5 is a light-shielding frame that covers the exposed area of the film, and 8
9 is a cartridge for storing the film, and 9 is a spool for winding the film.

6 is a cartridge holder, and 7 is a lens holder whose conical surface converging on the lens is treated to prevent stray light from entering.

In the specifications of the photographing unit mentioned above, the lens is f.
:8 to 6.3 spherical or aspheric fixed focus single lens, constant aperture, and shutter speeds of 1150 to 1/200 seconds.

As mentioned above, although it is a very simple camera with no exposure control mechanism, it is sometimes used at dusk or indoors when the amount of light is low, and high-sensitivity film is used. There is also a photography unit that comes with a strobe.

In addition to the risk of underexposure, there is also a strong risk of overexposure when photographing outdoors, resulting in images with poor gradation and insufficient color development. Especially when using a strobe, the day of the highlight part,
Tails and coloring are completely lost.

In order to improve color reproducibility, a technique has been disclosed that specifies the B, G, and R spectral sensitivities of photosensitive materials (hereinafter referred to as films) (Japanese Patent Application Laid-Open No. 72153/1983), but it is not possible to simply specify the spectral sensitivities. The arrow tension was insufficient. Also, a camera mechanism equipped with multiple filters for color correction (Japanese Patent Application Laid-Open No. 64-49027)
was proposed, but it has become clear that multiple filters are not required in practice, and it also poses a problem in terms of cost.

The particle size referred to here is the diameter of the circumscribed circle of the surface where the projected area of the particle is maximum.

X-ray photoelectron spectroscopy will be explained.

Prior to measurement by X-ray photoelectron spectroscopy, the emulsion is pretreated as follows. First, a pronase solution is added to the emulsion and stirred at 40° C. for 1 hour to decompose gelatin. Next, the emulsion particles are sedimented by centrifugation, and after removing the supernatant, an aqueous pronase solution is added and gelatin decomposition is performed again under the above conditions. The sample is centrifuged again, the supernatant liquid is removed, and then distilled water is added to redisperse the emulsion particles in the distilled water, centrifuged, and the supernatant liquid is removed. After repeating this water washing operation three times, the emulsion particles are redispersed in ethanol. This is applied thinly onto a mirror-polished silicon wafer to use as a measurement sample.

For measurements by X-ray photoelectron spectroscopy, for example, P
Using ES CA/S AM560 manufactured by H1, the excitation X-ray was M g -Ka ray, the X-ray source voltage was 15 KV,

By using 0.81.4°592, the composition ratio is given in atomic percent.

■ The average silver iodide content (J,) determined by the above-mentioned X-ray fluorescence analysis method and the X-ray microanalysis method were used to determine the halogenated grains located 80% or more away from the center in the grain diameter direction of the silver halide grains. When the average value (J,) of the silver iodide content measured on the silver crystal is compared, the relationship J r > J s is satisfied.

The X-ray microanalysis method will be explained.

Silver halide particles were dispersed in an electron microscope observation grid equipped with an X-ray analyzer and an electron microscope for energy dispersion, and the magnification was set so that one particle entered the field of view of the CRT with liquid nitrogen cooling, and the AgLa was heated for a certain period of time.

More preferably, the signal exists continuously over a diffraction angle of 1.5 degrees or more at the maximum height of the signal, XO,15. Furthermore, it is preferable that the diffraction angle at which the signal exists extends over 1.8 degrees or more, and particularly preferably over 2.0 degrees or more.

The presence of a signal means that the highest peak height X O,13
Alternatively, at 0.15, it means that the signal intensity is higher than that height.

A further preferred embodiment of the silver halide emulsion of the present invention is Cu
Also note that the above (420) X-ray diffraction signal using Ka radiation as a radiation source has two or three peaks. Particularly preferred is one having three peaks.

X-ray diffraction is a known method for investigating the structure of silver halide crystals.

Silver iodobromide has a rock salt structure and has a CuKa line < 42
0) Diffraction lines are observed between 2071 and 74 degrees. Since the signal intensity is relatively strong and the angle is high, the resolution is good, making it ideal for investigating crystal structures.

When measuring X-ray diffraction of a photographic emulsion, it is necessary to remove gelatin, mix with a standard sample such as silicon, and measure using a powder method.

Regarding the measurement method, refer to Basic Analytical Chemistry Course 24 "X-ray Analysis" (Kyoritsu Publishing).

It is 5% or less, particularly preferably 12% or less.

The relative standard deviation here is, for example, the value obtained by subtracting the standard deviation of the silver iodide content when measuring the silver iodide content of at least 100 emulsions by the average silver iodide content at that time x i
It is oo.

The silver halide emulsion of the present invention is cubic, tetradecahedral, 18
It may be a normal crystal like a hedron or a twin crystal like a tabular shape.

Alternatively, a mixture of these may be used.

It can be obtained by referring to the method for growing a spherical seed emulsion disclosed in the above publication.

During growth, it is preferable to add a silver nitrate aqueous solution and a halide aqueous solution by a double jet method. or,
It can also be supplied into the system as silver iodide. The addition rate is preferably such that new nuclei are not generated and the size distribution does not widen due to Ostwald ripening, that is, 30 to 100% of the rate at which new nuclei are generated.
