Abstract

PURPOSE:To know the photographing range of a camera even in the position to be photographed by mounting a projecting lens in the front surface of a camera main body incorporating a light source and an irradiation range specifi cation frame and equipping a device which makes the optical axis formed by the light source, the specification frame and the lens close to and parallel with the optical axis of an optical system for photographing in the camera. CONSTITUTION:A photographing range confirming device 10 is constituted of the light source 11 which lights at the time of using the camera X, a condenser 12, the specification frame 13 for adjusting the irradiation range to a photographing range and the projecting lens 14 of the aperture part of the front frame of the main body 1 and makes the axis parallel with the optical axis of the optical system for photographing. In case of usual photographing, a person in the position to be photographed can rapidly know whether he is within the photographing range by himself or if he goes to the position to be photographed after a timer is ON and he visibly recognizes the irradiated light from the light source part 11 through the lens 14, he can know that he is surely within the photographing range.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides photographing range confirmation that allows a person who is the subject to know that he/she is within the photographing range of the camera at the photographed position. This invention relates to a camera with a device.

(Prior art) As is well known, there is no technology for a person who is the subject to check whether he or she is within the shooting range of the camera at the shooting position.
At travel parties between like-minded people, one of the people often operates the camera and uses the self-timer to take commemorative photos, etc. At this time, the person operating the camera The photographic range was memorized in advance using the finder, and after activating the self-timer, the elephant was placed within the memorized photographic range.

(Problems to be Solved by the Invention) In short, from the beginning, the person in the position to be photographed trusts the camera operator's handling of the camera and its operating skills, and the camera operator during self-timer photography trusts his or her own memory. There was no other way but to trust.

Therefore, the operator of the camera during self-timer shooting may not appear in the photo, or the photo may have half of it missing, or even if he or she does appear in the photo,
Often the location was bad.

(Means for Solving the Problems) In view of the above-mentioned actual situation, the present invention provides an irradiation method for making the irradiation range of the light source section and the irradiation light from the light source section approximately the same as the photographing range of the camera. Attach the projection lens to the opening window on the front of the camera body, which has a built-in range regulation frame.
A photographing range confirmation device is attached to the camera at a position to be photographed in which the optical axis formed by the light source section, the irradiation range regulating frame, and the projection lens is close to and parallel to the optical axis of the photographing optical system of the camera, This camera is unique in that it allows you to know the photographing range of the camera even at the position where the photograph is being taken.

(Function) The camera with the device for confirming the photographing range at the position to be photographed according to the present invention has the above-described configuration, and when photographing,
When the light source section of the camera is turned on, the light emitted from the light source section is controlled by the irradiation range regulating frame so that the irradiation range is approximately the same as the shooting range of the camera, and the projection lens allows the irradiation range to be approximately the same as the shooting range of the camera. Since the same area will be illuminated, those who are within the camera's shooting range from the beginning will be able to see the lit light source, and will not be able to see the lit light source. Because it is invisible to those who are there,
You can know whether you are in the shooting range or not, and especially when one of the subjects uses the self-timer to take a photo, you can operate this camera and activate the self-timer. When you return to the photographed position, if you can see the lit light source, you are within the photographic range; if you cannot see it, you are outside the camera's photographic range.

(Example) In the following, we will mainly focus on the configuration of the main parts of the embodiment of the device for confirming the photographing range of a camera at a photographed position according to the present invention, and illustrations of other components will be omitted as much as possible to simplify the explanation. Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in FIG. 1, X is a camera in which the shooting range confirmation device according to the present invention is incorporated, and 1 is a camera body that forms the outer shell of the camera X and is also referred to as a camera body. , 2 is a lens barrel attached to the front of the camera body 1, 3 is a finder provided at the top of the camera body 1, which is also called a warship section, 20 is a window for a rangefinder, and 4 is a selfie camera. These are the knobs for operating the timer, which are exactly the same as those installed on ordinary cameras of this type up to now, and 10 is a knob for operating the timer. This is a shooting range confirmation device that allows you to know the range.

By the way, the photographing range confirmation device 10 installed in the camera body 1 includes a light source section 11, a condensing lens 12, a condensing lens 12, and a condensing lens 12, which are turned on when the camera An irradiation range regulating frame 13 disposed in front of the optical lens 12 and for adjusting the irradiation range of the irradiation light from the light source unit 11 condensed by the condensing lens 12 to the shooting range of the camera X, and the camera body 1 The projection lens 14 is arranged in this order, and its optical axis is parallel to the optical axis of the camera-3 optical system of the camera.

The camera X according to the present invention is equipped with the photographing range confirmation device 10 that can determine the photographing range of the camera X at the photographed position as described above. In this case, the person who is the subject at the position to be photographed can immediately know whether he or she is within the shooting range of camera X and can take measures to deal with this. When taking a picture, the person operating Camera Projection lens 1
If the irradiation light from the light source section 11 can be visually recognized through the camera X, the user can also know that he or she is within the photographing range of the camera X.

Therefore, the operator of camera X during self-timer photography can also take pictures within the photographing range of camera X.

Note that the light source section 11 in the above embodiment may use a reflector lamp instead of simply attaching a reflector behind the lamp and placing the condensing lens 12 in front of the reflector, or may use a light emitting diode as the lamp. In some cases, this lamp may also be used as a lamp to indicate the operation of the self-timer or a light emitting diode, or the knob for operating the self-timer may be converted into a switch and used to start the self-timer. It may also be made to light up accordingly.

(Effects of the Invention) As is clear from the above description, according to the present invention, it is possible to quickly know whether or not the subject is within the photographing range of the camera at the photographed position. When one of several people operates the camera and uses a self-timer to take a picture, it is now possible to provide a camera that allows each person to take a perfect picture as desired, instead of an incomplete picture.
