[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image capturing apparatus represented by a handy type camera having both functions of a still camera and a video camera.

[0002]

2. Description of the Related Art FIG. 27 shows a general image capturing device (SLR).
An example of how to guide the light flux to the finder 102 by the mirror 101 in FIG. As shown in this figure, a conventional lens optical system includes a main lens L as a main optical system, a mirror C04 and a mirror C04 as a light splitter that splits the light of a subject incident through the main optical system into two directions. It is composed of a film exposure surface B as a silver salt photographic image pickup section for picking up one of the split lights, and a finder for guiding the other light split by the mirror C04.

As another conventional example, an image photographing apparatus for photographing a video movie provided with electronic image stabilizing means is a single-lens type in which a single lens optical system is used for finder and photographing. Are configured in
In this case, instead of the type in which the light from the subject that has entered through the lens optical system is once refracted by the mirror and then imaged on the imaging surface, a CCD image sensor is placed on the same optical axis as the lens optical system and immediately behind it. It is arranged.

As another conventional example, there is one having a zoom mechanism and a wide viewfinder. In this case, the viewfinder has a wide viewfinder function by controlling the movement of the zoom lens.

[0005]

However, in the case of the general SLR lens optical system listed first, the focal plane 1
The angle of view of 03 is set to the angle of view corresponding to the mirror C04, the condenser lens (not shown), etc., and the outer peripheral portion of the image circle that extends beyond the angle of view is cut as an unnecessary portion and does not enter the viewfinder. Has become. For this reason, when this conventional configuration is applied to an image capturing apparatus having both functions of a still camera and a video camera, which is an object of the present invention, another optical system is required to add, for example, camera shake correction means or a wide viewfinder. Needing, etc.
There was a problem that the structure became complicated.

Further, in the case of another conventional example of a video movie camera with an electronic image stabilizer, as described above, the light from the subject is C on the optical axis of the main lens and immediately behind it.
A CD image sensor is arranged, and when this is applied to an image capturing apparatus having both functions of a still camera and a video camera, which is the object of the present invention, the still image capturing section is considered in relation to the video capturing section. Is difficult to arrange, and there is an inconvenience that the overall layout cannot be harmonized.

In the case of another conventional example having a zoom mechanism and a wide viewfinder, the wide viewfinder has a structure dependent on the zoom lens mechanism, so that the wide viewfinder can be realized in other photographing modes. Instead, the usage is limited.

The present invention has been made in view of the above conventional problems, and compares the image stabilization function and the wide view finder of the viewfinder in the image photographing apparatus having the functions of both the still camera and the video camera. It is an object of the present invention to be realized with a layout that is simple in structure and that can downsize the entire camera.

[0009]

In order to achieve the above object, according to the present invention, a main optical system, a light splitter for splitting the light of an object incident through the main optical system into two directions, and this light splitter. A silver salt photographic image pickup unit for picking up one of the light beams split by the light splitting unit, an electrophotographic image pickup unit for picking up the other light split by the light splitting unit, and an interposition between the electrophotographic image pickup unit and the light splitting unit And a relay optical system that allows the image pickup surface of the electrophotographic image pickup unit to be a wider image pickup surface than the image pickup surface of the silver salt photograph image pickup unit including all image pickup formats of the silver salt photography system. It constitutes a light splitter and a relay optical system.

In addition to the above-mentioned structure, in the electronic camera shake correcting means, a portion of the image pickup surface of the electrophotographic image pickup section, which extends outside the area corresponding to the image pickup surface of the silver salt photograph image pickup section, is moved by the electronic camera shake. It can be used as a correction area in the correction means.

Further, in a device having an electric display element capable of displaying an image by the electrophotographic image pickup section in real time, it spreads outside the area corresponding to the image pickup surface of the silver salt photograph image pickup section in the image pickup surface of the electrophotographic image pickup section. The part can be used as an area of a wide viewfinder.

[0012]

According to the above configuration, the light of the subject incident from the main optical system is guided to the image pickup surface of the electrophotographic image pickup section through the light splitter and the relay optical system. In this case, the configuration of the light splitter and the relay optical system is used. As a result, the image pickup surface of the electrophotographic image pickup unit becomes wider than the image pickup surface of the silver salt photograph image pickup unit.
Assuming that the light irradiation amount on the image pickup surface of the silver salt photographic image pickup unit is 100, 100 or more lights are radiated from the main optical system to the image pickup surface of the electrophotographic image pickup unit. Therefore, this margin of light can be used as an area for electronic image stabilization or as a wide viewfinder.

In the example shown in FIG. 11, the CCD image sensor C21 has a wide size (16: 9) and the film exposure area and the image area of the CCD are substantially equal. The screen size for movies requires the image stabilization area to be secured, so the print area of the same standard (H)
In contrast, it is slightly smaller. The print area (H) is 90% smaller than the film exposure area.

In the example shown in FIG. 12, the CCD image sensor C21 is of a wide size and is provided with a sufficient image stabilization area for the film exposure area. The screen size at the time of movie is the same as the silver salt format of the same standard. Therefore, the camera shake correction switch (camera shake correction control ON / OFF button COP15) is turned off.
The screen size does not change regardless of N / OFF.

As described above, according to the present invention, the light of the subject incident through the main optical system is split into two directions by the light splitter, and one of the split lights is input to the silver salt photographic imaging section. In the optical system configured so that the other light reaches the electrophotographic image pickup unit via the relay optical system, the image pickup surface of the electrophotographic image pickup unit is wider than the image pickup surface of the silver salt photograph image pickup unit. Since the optical splitter and relay optical system are configured, in an image capturing device that has the functions of both a still camera and a video camera, a wider angle of view than the silver salt format or the video format can be obtained on the image capturing surface of the electrophotographic image capturing unit. Therefore, the light margin is used as an electronic image stabilization area for a wide angle of view as in claim 2 or as a wide viewfinder as in claim 3. It can be used.

Further, by using the margin of the light of the subject illuminated on the image pickup surface of the electrophotographic image pickup unit for the above-mentioned application, the layout of the entire apparatus is harmonized and compact. It is possible to achieve excellent effects not seen in the past.
