BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact zoom camera, and more particularly, to a parallax correcting apparatus of a compact zoom camera for correcting the disparity of a finder lens unit and a photographing lens unit in close-up photography.

In general, a compact zoom camera is composed of a photographing lens unit for collecting light to form an image on the film, and a finder lens unit for confirming the photographing range with the eyes of the photographer, and light is introduced until the end of shooting. The shutter is opened by pressing the release button to prevent the light from being blocked, and the shutter is configured to receive an appropriate amount of light to light the film.The amount of light flowing through the hole formed like the pupil of the eye is formed. According to the aperture is configured to combine the ring-shaped metal plate to adjust the size of the hole large or small. And it is composed of a body formed of a dark box to embed and attach these components or to block the film from the external light.

Unlike a single lens reflex (SLR) camera, a zoom camera having such a structure has a range A and a photographing lens in which the subject P can be identified through the finder lens unit 10 as shown in FIG. 1. The parallax phenomenon in which the range B actually photographed is different through the unit 20 is generated. The parallax phenomenon is more severe as the photographing distance is shorter.

The cause of the parallax phenomenon as described above will be described with reference to FIG. The conventional finder optical system is composed of an objective lens 11, a zoom lens 12, an intermediate lens system 13, and an eyepiece 14, and the light focused on the lens of the finder optical system is 360 °, that is, in any direction. Even when the light is collected or the subject is caught in the human eye after passing through a certain lens system, the subject has a limited characteristic according to the lens system.

For example, when the light a is incident out of a predetermined angle α ° through the objective lens 11, the light a passes through the intermediate lens system 13 and then exits without being caught in the eyes of the photographer. . That is, this phenomenon is caused by the refractive index of the lens itself according to the characteristics of the lens system.

In order to correct the parallax that occurs during close-up photography, the near-field shot range is located inside the far field view 151, which shows a far-field shot range of the field-of-view lens 15 installed in front of the eyepiece as shown in FIG. A near-parallax correction mark 152 is formed.

However, photographing a range closer to the range indicated by the near-field disparity correction mark 152 of the field-of-view lens 15 as described above may not only allow the photographer to compose the composition but also such a state. When taking a picture in, the image of the subject differs from the range checked through the finder, and the actual photographed range is different.

Accordingly, the present invention has been made in view of the above-mentioned general defects, and its object is to provide a compact zoom camera for correcting the parallax between the finder lens unit and the photographing lens unit to a minimum state when photographing close range. A parallax correction device is provided.

The parallax correction device is characterized in that it comprises a parallax correction lens which is selectively installed and removed between the zoom lens of the finder lens unit and the intermediate lens system when photographing at a close distance.

Hereinafter, the configuration of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 4 is a configuration diagram of the finder optical system to which the present invention is applied, and FIG. 5 is a parallax explanatory diagram at the time of close-up photography to which the present invention is applied.

The finder lens unit 10 to which the present invention is applied is arranged in the order of the objective lens 11, the zoom lens 12, the intermediate lens system 13, and the eyepiece 14 as usual.

In the finder optical system, the present invention comprises a parallax correction lens 30 that is selectively installed and removed between the zoom lens 12 of the finder lens 10 and the intermediate lens system 13. Explained as follows.

The parallax correction lens 30 of the present invention configures the lens to have different thicknesses of the upper and lower sides by using the principle of refraction of the light of the lens itself, that is, the incident light is refracted in the thick direction of the lens. For example, as shown by the dotted line in FIG. 4, when checking the eye of the photographer to the range of the light (a) incident to the bottom, the front of the parallax correction lens 30 is vertically constructed and the bottom is referred to. The thickness of the upper part is made thin.

When the disparity correcting lens 30 configured as described above is installed between the zoom lens 12 and the intermediate lens system 13 and the light a biased downward is incident on the parallax correction lens 30, the light is thin at the top. It is refracted downward through and corrected within the range that can be seen by the photographer's eyes.

When taking a close-up photographing using the parallax correction lens 30 having a constant refractive index change as described above, the finder lens unit 10 is enlarged as shown in FIG. The parallax phenomenon is minimized in which the range (A) and the actually photographed range (B) are different from each other.

In addition, the parallax correction lens 30 of the present invention should be configured to be selectively used only for close-up photography. The configuration of the embodiment may include a hinge 31 that rotates in one direction at a lower end of the parallax correction lens 30. In long distance shooting, the quasi-correction lens 30 is removed in a horizontal state in one direction, and in the long distance shooting, the parallax correcting lens 30 is folded in a horizontal state to expand the zoom lens 12 and the intermediate lens system 13. Install in between. The adjusting means of the parallax correction lens 30 may be mechanically changed according to the structure of the camera.

As described above, the present invention provides a confirmation range through the finder lens unit which can check the subject P during close-range photography by selectively installing a parallax correction lens between the zoom lens of the finder lens unit and the intermediate lens system when photographing the close range. It will have the advantage of maximizing the reliability of the product by minimizing the parallax phenomenon that the actual shooting range of the photographing lens unit is different.
