Abstract

The utility model relates to a reflector which can make a sitter observe the states of the sitter when the sitter is photographed, particularly a wide viewing field reflective self-view lens for a camera. When the sitter is photographed, the harmony of the posture of the sitter, and ambient environment can not be mastered by the sitter, after photographing, a photograph is always not satisfied. The utility model is mainly provided with a flat mirror at a concave lens. The principle is disclosed in the specification 2. The light line of an objective image human 1 is considered as a virtual image 5 by a person's eyes through the reduction function of the concave lens 2 and the reflection function of the flat mirror 3. The utility model causes the posture of the sitter to be known by the sitter through observing the concave lens, the ambient environment can be harmonized, and the satisfied photograph is photographed.

Description

Take a picture with the reflection of the wide visual field from visor

The utility model relates to a kind of when taking a picture, and can make the person taken picture observe the catoptron of own state of living in.

During photograph, person taken picture's attitude, and often can not observe grasp by the he or she with the coordination of surrounding environment, can only be subjected to controlling of camerist.And can not predict the general sight of own institute photograph sheet, often cause afterwards satisfied not to the utmost to institute's photograph sheet.Certainly, can observe, but its required minute surface is too big, impracticable with level crossing.

The purpose of rate utility model just provides a kind of wide visual field and reflects white visor, and it can make the person taken picture observe own residing state, thereby breaks forth oneself satisfied photograph.

The purpose of this utility model is achieved in that

In the concavees lens back that a rectangular one side is the plane, place a level crossing.During photograph, place it in the camera top, the person taken picture observes concavees lens.According to the concavees lens refraction principle, image is collected and is contracted by behind the concavees lens, returns through flat mirror reflects, and the person taken picture promptly can be observed a mirror image that the visual field is bigger.Its mirror image and camerist by camera see unanimous on the whole, thereby can understand own state of living at any time, take desirable photograph.

The utility model, by concavees lens dwindle the effect and the reflex of level crossing, can make the person taken picture utilize less minute surface, can grasp own state of living in, and with same coordination of enclosing environment, thereby take desirable photo as the case may be.

Principle of the present utility model and concrete structure are provided by accompanying drawing.

Fig. 2 is a schematic diagram of the present utility model, and image is gone into 1 the light reflex of dwindling effect and level crossing 3 by concavees lens 2, can be viewed as the virtual image 5 by eye 4.

Fig. 1 reflects sectional view from visor according to the photograph that the utility model proposes with the wide visual field." A-A section " is the one section.

Describe the details of the concrete device that the utility model proposes in detail below in conjunction with Fig. 1.

This device comprises a rectangular concavees lens main body 1, is a level crossing 2 in the concavees lens back, and there is a framework 3 that plays the support effect outside.

Concavees lens 1 should simultaneously be the plane, and another side is recessed.The minification of concavees lens 1 should make by the observed mirror image of photograph person viewed consistent by camera with camerist.One side one side on concavees lens 1 plane is a level crossing 2.A bit of distance is arranged between level crossing and the concavees lens, it is contacted with each other, should be between the 1-3 millimeter.Place portion framework 3 covers on concavees lens and support, protective effect are played in the level crossing outside.The length breadth ratio of whole device should be consistent with the length breadth ratio of real pictures, and ratio is preferably 0.70.

Claims

1, a kind of photograph from visor, comprises concavees lens (2) with the reflection of the wide visual field, and level crossing (3) is characterised in that concavees lens simultaneously are the plane, and one side on the plane is provided with a level crossing.

2, reflection according to claim 1 is from visor, and it is viewed consistent that the minification that it is characterized in that concavees lens should make viewed mirror image of person taken picture and camerist see through camera.

3, reflection according to claim 1 is characterized in that between level crossing and the concavees lens a bit of distance being arranged from visor, and its width should be the 1-3 millimeter.

4, reflection according to claim 1 is characterized in that from visor level crossing and concavees lens all should be rectangle, and its length breadth ratio should be 0.70.
