DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide camera provided with a photographing means for performing a photographing operation for recording a subject image to be recorded on a silver halide film.

[0002]

2. Description of the Related Art A silver halide camera records an image of a subject formed on a silver halide film, which is a photosensitive material responsive to light, through a photographic optical system as a latent image on the silver halide film. Various types of lenses have been put into practical use, from the so-called compact type in which the lens cannot be replaced to the single-lens reflex type in which the lens can be replaced.In recent years, attention has also been focused on increasing the magnification of the imaging system and reducing the size and weight of the overall configuration. ing.

[0003] Regarding the storage and storage of the subject image obtained by the silver halide camera, the film itself after development processing is stored and stored, and therefore, the storage and storage in various storage media in a digital camera described later. Unlike storage, even when magnetism or light is supplied, the recorded subject image is not degraded or destroyed.

However, since the obtained data is not digital data, it is not easy to confirm, process, and transmit the image immediately after photographing the subject image.

On the other hand, a digital camera converts an optical subject image formed on an image pickup device such as a charge-coupled device (CCD) or a C-MOS sensor that performs photoelectric conversion via a photographing optical system into an image of the image pickup device. It is converted into electrical image data and recorded on an appropriate storage medium. Like the silver halide camera, there are various practical applications from the so-called compact type that can not exchange lenses to the single-lens reflex type that can exchange lenses. In recent years, its spread has been significantly advanced.

[0006] Naturally, the obtained data is digital data, and, like the silver halide camera described above, not only can the zooming of the photographing system be made high and the overall configuration can be made compact, but also
Attention has also been paid to increasing the number of pixels in the image sensor, and most digital cameras in recent years have a built-in strobe device as an artificial illumination source at the time of photographing.

Since the digital camera can obtain digital data as described above, it is possible to easily confirm a subject image immediately after shooting, process the subject image, transmit an image over a network, and the like.

[0008] Considering the preservation and storage of this digital data, usually, it is printed out, or a floppy (registered trademark) disk (FD), a compact flash (registered trademark) card (CF), a mini disk (MD) And storage using various known storage media such as a semiconductor memory.

Therefore, apart from storage and storage in print, when storage and storage in a storage medium are considered, the same source as magnetism, light, or the like as an operation source for writing data to the storage medium is used. If the action source is supplied carelessly, there is a risk that the digital data stored up to that point will be degraded or possibly destroyed.

Therefore, a camera having both advantages of a silver halide camera and a digital camera has been disclosed in Japanese Patent Laid-Open No.
A camera disclosed in Japanese Patent Application Laid-Open No. 1-52468 has been proposed.

In brief, the proposed camera comprises a first recording means for recording a subject image on a silver halide sensitizer, an image sensor for photoelectrically converting the subject image into digital image data, and a storage medium for storing the image data. , A display means for displaying data, and a shutter means for recording an object image on the silver halide sensitizer by one operation and obtaining image data.

[0012]

The above-mentioned proposed camera obtains a subject image as digital image data and records it on a silver halide film, so that the disadvantages of both the digital camera and the silver halide camera are compensated for each other, and the image of the subject is compensated for. The effect that confirmation and processing can be easily performed and a high-quality image can be obtained can be expected.

However, when considering the practical use of the above proposed camera, it goes without saying that the specific structure for realizing the functions of both the silver halide camera and the digital camera is complicated, and as a result, the cost is also reduced. It has to be expensive.

That is, in order to obtain the above-mentioned effect, the camera user needs to obtain the above-mentioned proposed camera newly, and if the user has a silver halide camera or a digital camera until now, Has the disadvantage that an additional and expensive expense is incurred.

The present invention has been made in view of the above points. If the user already owns a digital camera, the advantages of both a silver halide camera and a digital camera can be obtained without incurring an expensive cost, especially, an image on a storage medium. An object of the present invention is to provide a silver halide camera that can eliminate anxiety about data storage and storage.

[0016]
