Abstract

PURPOSE:To make a person to be photographed easily know whether his own position is within the photographing range or not by providing a surface light source for radiating light in the direction of an object and an opening for getting a distant view of the light source from the object side. CONSTITUTION:A camera in the title comprises a surface light source 2 for radiating light in the direction of an object and a window 3 which has a larger open area than the surface light source 2 and is disposed in front of the light source 2. In this case, when a person to be photographed is located in the central portion, the peripheral portion in the photographing range and in the outside of the photographing range, respectively, the appearing way of a LED 2 provided on the camera 1 is varied. Thus, it is possible to immediately judge visually whether a person to be photographed is located in the photographing range or outside of the photographing range. When a person to be photographed is located in the photographing range, it is also possible to judge visually whether the person is located in the central portion of the photographing range or in the peripheral portion thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a camera, and more particularly to a camera configured so that a person as a subject can know the shooting range.

[Prior Art] Conventionally known cameras are not provided with a means for the person to be photographed to know the photographing range.

[Problem to be solved by the invention] Therefore, when taking a picture using the camera, there was a drawback that the person being photographed could not judge whether he or she was within the photographing range or outside the photographing range. . Also,
Even when the photographer is the subject in photography using a self-timer, there is a drawback in that the photographer cannot immediately know the shooting range.

An object of the present invention is to provide a camera that allows a person to be photographed to know the photographing range.

[Means for Solving the Problems] The camera of the present invention includes a planar light source that emits light in the direction of a subject, and a window that has a larger opening area than the planar light source and is arranged in front of the light source. The camera is configured so that the person to be photographed can see the photographic range of the camera by viewing the light source from a distance through the window.

[Function] With the camera of the present invention, when the person to be photographed looks at the light source through the window, the person to be photographed can know the photographing range based on the position within the window where the light source is visible.

[Examples] Examples of the present invention will be described below with reference to the drawings.

A first embodiment of the present invention is shown in FIGS. 1 and 2. FIG. In the figure, 1 is the camera body, 2 is an LED which is a surface light source,
3 is a window or opening provided at a position facing the LED 2; 4 is a frame provided to form the opening 3; and 5 is a photographing lens. FIG. 2 is a plan view of FIG. '81 seen from above. In the figure, α is an angle indicating the left and right shooting range of the shooting range determined by the lens 5;
β is the line connecting the right end of LED2 and the right end of opening 3 and the LED
This is the angle formed by the line connecting the left end of 2 and the left end of opening 3. As shown in the figure, the LED 2 and the opening 3 are aligned with the camera so that the angle α between the line connecting the left end of the LED 2 and the right end of the opening 3 and the line connecting the right end of the LED 2 and the left end of the opening 3 is It is arranged within the main body 1.

FIG. 3 is a diagram showing the photographing range when photographing is performed using the camera provided with the LED 2 and the opening 3 as described above. In the figure, ■ indicates a central portion within the photographing range of the camera 1, I+ represents a peripheral portion within the photographing range, and III represents a portion outside the photographing range of the camera 1. When the person to be photographed looks at the LED 2 provided in the camera 1 in the central portion I of the photographing range, the entire LED 2 can be seen within the frame 4, as shown in FIG. 4(a). Furthermore, when the subject looks at the LED 2 at the peripheral area I+ of the photographing range, the right side of the LED 2 is blocked by the right end of the opening 3, and only a portion of the left side of the LED 2 is visible within the frame 4, as shown in Fig. 4(b). Become invisible. Furthermore, the subject is located at a portion I outside the shooting range of the camera 1.
When looking at the LED 2 in II, as shown in FIG. 4(c), the LED 2 is completely obstructed by the right end of the opening 3 and cannot be seen within the frame 4 at all.

As mentioned above, the appearance of the LED 2 installed on the camera 1 changes depending on whether the subject is in the center of the shooting range, on the periphery, or outside the shooting range, so whether the subject is within the shooting range or not. Alternatively, it is possible to immediately determine visually which side of the photographic range the person is on. Furthermore, if the person to be photographed is inside the photographing range, it is possible to immediately determine by visual observation which side of the photographing range, the central part or the peripheral part.

In addition, in the above description, only the left and right directions within the photographing range have been described, but it goes without saying that similar effects can be obtained in the up and down directions as well.

5 and 6 show a second embodiment of the present invention. In the figure, 11 is a camera body, 12 is an LED which is a surface light source, 13 is an opening provided at a position facing the LED 12, 14 is a movable frame provided to form the opening 13, 15 is a zoom lens, α is an angle that indicates the horizontal range of the shooting range when the zoom lens 15 is set to the wide-angle side, and α゛ is the horizontal range of the shooting range when the zoom lens 15 is set to the telephoto side. The angle shown is,

The frame 14 has a configuration shown in FIG. 6, and at any angle of view of the zoom lens 15, a line connecting the left end of the LED 12 and the right end of the opening 13 is connected to the right end of the LED 12 and the opening 13.
The camera moves in the direction of the arrow in the figure so that the angle formed by the line connecting the left ends of the camera matches the angle that indicates the horizontal range of the imaging range. In other words, when the zoom lens 15 is on the wide-angle side or the telephoto side, as shown in FIG. 5, when the zoom lens 15 is on the wide-angle side, the frame is
The frames are provided at positions a and 14b, and when the zoom lens 15 is on the telephoto side, the frames are provided at positions 148° and 14b'.

By using the movable frame shown above, even with a zoom lens whose angle of view changes, the subject can be photographed in the central part within the photographing range, in the peripheral part, outside the photographing range, etc., as in the first embodiment. Since the appearance of the LED provided on the camera changes depending on where the camera is located, the same effect as in the first embodiment can be obtained. Although a camera is used in this embodiment, the same effect can be obtained by using a video movie as well.

Furthermore, if the present invention is applied to a camera with a self-timer, an even greater effect can be obtained.

That is, since cameras with a self-timer are generally equipped with an LED for warning during self-timer shooting, by using the LED shown in the first and second embodiments as the self-timer LED, the self-timer During timer photography, the same effect as in the first embodiment can be obtained not only for the person to be photographed, but also when the photographer turns to the subject after pressing the shutter button.

[Effects of the Invention] As explained above, the camera of the present invention has a planar light source that emits light in the direction of the subject and an opening that allows the light source to be viewed from the subject side. The photographer can easily know whether or not his or her position is within the photographing range by looking far away to see where the light source can be seen within the opening.
