According to a fifth aspect of the present invention, in the light receiving processing device for a camera according to any one of the first to fourth aspects, the imaging device is a CMOS or a CCD.

[0011]

Embodiments of the present invention will be described below. FIG. 1 is an explanatory diagram of a light receiving processing device of a camera according to a first embodiment of the present invention. FIG. 1A is a perspective view of the light reception processing device 1 of the camera, and FIG. 1B is a perspective view of the case where the light reception processing device 1 of the camera is housed in the camera body.

The light receiving processing device 1 of the camera comprises a cylindrical portion 2 corresponding to a film main body and a plate portion 3 corresponding to a film portion drawn from the film main body. The battery is stored in the cylindrical portion 2 and stored in the film main body storage portion 4 of the camera.

The plate portion 3 is provided so as to protrude from the cylindrical portion 2, and the plate portion 3 is provided with an image pickup device 5 for receiving light of a subject from a lens and obtaining an image pickup signal. Reference numeral 5 indicates that when the cylindrical portion 2 is normally stored in the film main body storing portion 4 of the camera, light of the subject from the lens can be received. As the imaging device 5, a CMOS (complementary metal oxide semiconducto) is used.
r) or using a CCD. CMO is the key to miniaturization
It is desirable to use S.

The plate section 3 has a logic operation section 6 for processing an image signal obtained by the image sensor 5 and a storage section 7 for storing the image signal.

When a normal camera is used as a digital camera, a light receiving processor 1 of the camera is used instead of a film.
Is usually set on the camera body. That is, the cylindrical portion 2 of the light reception processing device 1 of the camera is inserted and stored in the film body storage portion 4 of the normal camera body. Thereby, the imaging element 5 of the plate unit 3 is arranged at a position where the light of the subject from the lens can be received.

Then, the battery housed in the cylindrical portion 2 is turned on by a switch (not shown), and power is supplied to the logical operation portion 6 and the like built in the plate portion 3. Thereby, the function as a digital camera is exhibited, and the normal camera can be used as a digital camera.

On the other hand, when used as a normal camera, it goes without saying that the film main body is stored in the film main body storage section 4 and the film is set and used.

According to the first embodiment, when a normal camera is used as a digital camera, it can be used as a digital camera only by setting the light receiving processing device 1 of the camera in the film main body storage section 4. Further, the film main body can be set in the film main body storage section 4 and used as a normal camera. Therefore, there is no need to purchase a digital camera separately from a normal camera.

Next, a second embodiment of the present invention will be described. FIG. 2 is a side view when a light receiving processing device 1 of a camera according to a second embodiment of the present invention is mounted on a normal camera.

The light reception processing device 1 of the camera comprises a plate portion 3 and is mounted inside the lid 8 of the camera. A liquid crystal 9 for displaying an image signal is provided outside the lid 8. In addition, the battery stored in the cylindrical portion 2 due to the omission of the cylindrical portion 2 can be located at any position in the camera body,
For example, it is attached to the bottom of the camera body.

As in the first embodiment, the plate section 3 is provided with an image sensor 5 for converting the light of the subject from the lens into an electric signal to obtain an image signal, facing the lens. A logic operation unit 6 for processing the image signal obtained by the element 5 and a storage unit 7 for storing the image signal processed by the logical operation unit 6 are provided therein. The liquid crystal 9 displays an image signal of a subject from a lens and an image signal stored in the storage unit 7.

When this normal camera is used as a digital camera, it is confirmed that the film main body is not stored in the film main body storage section 4, the battery is turned on by a switch (not shown), Power is supplied to the logical operation unit 6 and the like. Thereby, the function as a digital camera is exhibited, and the normal camera can be used as a digital camera.

On the other hand, when used as a normal camera, it goes without saying that the film main body is stored in the film main body storage section 4 and the film is set and used.

According to the second embodiment, when a normal camera is used as a digital camera, it can be used as a digital camera simply by turning on the switch of the light reception processing device 1 of the camera. Further, the film main body can be set in the film main body storage section 4 and used as a normal camera. Therefore, there is no need to purchase a digital camera separately from a normal camera.

Next, a third embodiment of the present invention will be described. FIG. 3 is a side view when the light receiving processing device 1 of the camera according to the third embodiment of the present invention is mounted on a normal camera. The third embodiment is different from the second embodiment shown in FIG. 2 in that the light reception processing device 1 of the camera is attached to the main body of the normal camera instead of the cover 8 of the normal camera. The other configuration is the same as that of the second embodiment. Therefore, the same components are denoted by the same reference numerals and description thereof will be omitted.

Here, a metal (iron), a ceramic, a plastic, or the like is used as a material of the main body of the light reception processing device 1 of the camera in each of the embodiments described above.

[0027]

As described above, according to the present invention, since a normal camera can be used as a digital camera, it is not necessary to have two cameras, a normal camera and a digital camera, and a digital camera is provided separately from the normal camera. No need to buy a camera.
