Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic camera having an image sensor and a monitor for displaying a rectangular image obtained from a video signal from the image sensor. The present invention relates to a technique for selectively changing a position.

2. Description of the Related Art In a general silver-salt camera, the film has long sides in the horizontal direction, and when a subject is long in the vertical direction or dispersed in the vertical direction, the whole image is taken. For example, a so-called zoom back is used with a zoom lens having a wide angle, or the camera itself is vertically held for shooting.

However, in a camera fixed to a tripod and looking at the finder from above, even when the subject is long in the vertical direction or dispersed in the vertical direction,
It is not possible to shoot with the camera fixed vertically. Because in that case, the viewfinder is located on the side, but it is physically difficult to see the viewfinder on the side.

Therefore, in some models of medium format silver salt cameras called 120 type, a square image pickup area is used.
When the subject is long or dispersed in the vertical direction or the horizontal direction, a method of enlarging at the time of printing and cutting out only the portion where the subject is reflected is used.

Some large format silver salt cameras called 4 × 5 type have a structure in which the film storage section rotates 90 degrees, and the subject is long in the vertical direction or dispersed in the vertical direction. In this case, the film storage section is rotated by 90 degrees so that the long side of the film is in the vertical direction, and then the image is taken.

On the other hand, for an electronic camera, a method has been proposed in which an image pickup device such as a CCD is rotated by 90 degrees as in the case of the large format silver salt camera (Japanese Patent Laid-Open No. 10-65975). FIG. 5 is a plan view showing the concept of a rotation mechanism of an image pickup element of the electronic camera of the conventional example. In FIG. 5, 10 is an image sensor, 11
Is a mounting plate for the image sensor, and 12 is a rotary motor for rotating the image sensor. In the conventional example, the image sensor 10
Is mounted on a mounting plate 11, and the mounting plate 11 is rotatably or rotatably held by a rotary motor 12 in a housing (not shown). The center of the rotary shaft of the rotary motor 12 is at the center of the image sensor 10.
The image pickup element 10 rotates with the center of the image pickup surface as the center point. Then, for example, when the subject is vertically long, the image is taken with the long side of the image pickup device 10 in the vertical direction.

[0007]

In the electronic camera, when fixed on a tripod or the like for framing, it is necessary to rotate the photographing monitor at the same time by 90 degrees at the same time as the image pickup device, which is structurally complicated and costly. There is a drawback that it costs.

An object of the present invention is to fix the length of the subject when shooting a subject that is long in the vertical direction or dispersed in the vertical direction in an electronic camera of a type that is fixed to a tripod at the time of shooting and the monitor is viewed from above. You can press the shutter button while viewing the monitor in a natural posture by aligning the direction with the direction of the long side of the rectangular image obtained from the image sensor and the long side of the shooting monitor. It is to provide an electronic camera that can take a picture.

In the present specification, when the subject is long in the horizontal direction or dispersed in the horizontal direction,
The horizontal image is taken with the long side of the rectangular image obtained from the image sensor in the horizontal direction, and the rectangular image obtained from the image sensor when the subject is long in the vertical direction or dispersed in the vertical direction. Shooting with the long side of the vertical direction is referred to as vertical shooting.

[0010]

In order to solve the above-mentioned problems, the photographing monitor is detachable, the electronic camera is provided with two mounting terminals for the photographing monitor, and vertical photographing and horizontal photographing can be performed. Make it possible to change the mounting position.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an electronic camera according to an embodiment of the present invention at the time of lateral position photography. FIG. 2 is a perspective view of the electronic camera according to the embodiment of the present invention during vertical position shooting. Figure 3
FIG. 6 is a perspective view of the camera body at the time of lateral position photography according to the embodiment of the present invention. FIG. 4 is a perspective view of the photographing monitor. Figure 1
1 is an electronic camera body, 2 is a photographing monitor for displaying a rectangular image obtained from an image sensor, 3 is a shutter button, and 4 is a vertical position monitor connection terminal. Figure 2
5 is a tripod mount for lateral position. In Figure 3
6 is a lens, 7 is an image pickup device, and 8 is a lateral position monitor mounting terminal. In FIG. 4, 9 is a contact.

FIG. 1 is a perspective view of the electronic camera according to the present invention at the time of lateral position photographing, in which a lateral position monitor mounting terminal 5 of the electronic camera body 1 (not visible because it is hidden by the monitor 2 in the figure) is used. The shooting monitor 2 is detachably attached. In this state, the long side of the rectangular image obtained from the image sensor and the long side of the monitor are in the horizontal direction, which is suitable for shooting when the subject is long in the horizontal direction or dispersed in the horizontal direction. In this state, the vertical monitor connection 4
Is not used. Also, when shooting horizontally or vertically, the user can press the shutter button with either the vertical position or the horizontal position. Shutter button 3 is provided at the lower left two places. Here, the shutter button is an electronic camera that presses the shutter button to record an image signal converted from an optical signal by an image sensor and an image signal generation circuit on a recording medium built in the electronic camera. Is something that causes

FIG. 6 is a rectangular image obtained by photographing the electronic camera according to the present invention at the lateral position photographing shown in FIG.

FIG. 2 is a perspective view of the electronic camera according to the present invention during vertical position photography. This is the one in which the electronic camera in the state of FIG. 1 is rotated 90 degrees clockwise when viewed from the surface opposite to the surface with the lens, and the shooting monitor 2 is replaced with the monitor connection terminal 4 for vertical position. Is. In this state, the long side of the rectangular image obtained from the image sensor and the shooting monitor
The long side of 2 is the vertical direction, which is suitable for shooting when the subject is long in the vertical direction or dispersed in the vertical direction.
