Stereoscopic microscope with stereoscopic image acquisition device and stereoscopic image acquisition device {APPARATUS FOR OBTAINING STEREOGRAPHIC AND STEREOGRAPHIC MICROSCOPE THEREWITH}

The present invention relates to a stereoscopic microscope having a stereoscopic image acquisition device and a stereoscopic image acquisition device. More particularly, the right eye image and the left eye image of an object are easily aligned to obtain a stereoscopic image, and the stereoscopic image is a stereoscopic image. The present invention relates to a stereoscopic microscope including a stereoscopic image acquisition device and a stereoscopic image acquisition device that output a display to display a two-dimensional plane image of an object as a three-dimensional stereoscopic image.

A microscope is a device that magnifies a small object or microorganism that is difficult or impossible to observe with the human eye. The microscope enlarges an image of an object according to the magnification of a lens system to form an enlarged image and provide it to an observer.

In addition, the microscope is classified into a monocular microscope and a binocular microscope according to the number of lens systems, and a person observes an enlarged image of an object by placing an eye on one end of the barrel.

Recently, a microscope has been developed in which an image formed on a microscope is exposed to an image sensor and is displayed on a large display device such as an LCD.

On the other hand, the three-dimensional image display device is divided into a glasses method for wearing polarized glasses and observing three-dimensional images by using different polarizations of the display device and a glassesless method for dividing the left and right images in space according to the position of the observer's eyes. Can be.

In addition, the glasses-free method is a typical example of the lenticular (Benticular) method and the barrier (Barrier) method, the glasses-free method is excellent because it does not wear glasses, but the phenomenon that the stereoscopic image is broken when the observer moves left and right, back and forth There is a disadvantage in that the resolution degradation inevitably occurs because the left and right images are output using a single display.

In addition, the glasses method has the disadvantage of having to wear polarized glasses that act as an optical filter, but there is an advantage that compared to the glasses-free method in terms of viewing angle or resolution.

On the other hand, in order to maintain a stereoscopic image of a stereoscopic image display apparatus at high resolution, two conditions must be satisfied, one of which is a distance condition that must maintain a constant focal length between the lens system and the image sensor, and the other is the lens system. The left eye image and the right eye image to be imaged are positional conditions that should be exposed to the image sensor at a predetermined position.

Therefore, when acquiring the left eye image and the right eye image necessary for synthesizing the stereoscopic image, the stereoscopic image generated by the stereoscopic image display apparatus may cause geometric distortion if the distance condition and the location condition are not satisfied at the same time.

In general, the distance condition depends on the characteristics of the image sensor, but usually requires a short distance of about 5 ~ 15mm.

5 shows a third embodiment of a stereo microscope according to the present invention.

Hereinafter, descriptions of the same components as those of FIGS. 2 and 3 will be omitted.

Referring to FIG. 5, a third embodiment of the stereoscopic microscope of the present invention includes a right eye lens system 310, a left eye lens system 320, a right eye image acquisition device 200, a left eye image acquisition device 200a, a signal processor 400, It includes a stereoscopic image display unit 500 and a storage PC (600).

The right eye lens system 310 forms an image of a right eye of an object and delivers the image to the right eye image obtaining apparatus 200, and the left eye lens system 320 forms an image of a left eye of the object and transmits the image to the left eye image obtaining apparatus 200a.

The right eye image acquisition apparatus 200 acquires the right eye image signal by dimming the right eye image, and has the same configuration as the image acquisition apparatus 200 shown in FIG. 2.

The left eye image acquisition apparatus 200a receives the left eye image to obtain a left eye image signal, and has the same configuration as that of the image acquisition apparatus 200 shown in FIG.

In addition, the left eye image acquisition apparatus 200a is coupled to the left eye lens system 320 by rotating the right eye image acquisition apparatus 200 by 90 degrees or -90 degrees on a plane.

However, since both the right eye image acquisition apparatus 200 and the left eye image acquisition apparatus 200a may move the image sensor module 120 in the first axial direction a and the second axial direction b, the The left eye image acquisition apparatus 200a may not be rotated and combined.

That is, since the positions for acquiring the left eye image signal and the right eye image signal can be adjusted, the user can more easily satisfy the positional conditions of the images.

In the above, the configuration and operation of the present invention has been shown in accordance with the above description and drawings, but this is merely described, for example, and various changes and modifications are possible without departing from the spirit and scope of the present invention. .

1 is a view showing a first embodiment of an image acquisition device according to the present invention;

2 is a view showing a second embodiment of an image acquisition device according to the present invention;

3 shows a first embodiment of a stereo microscope according to the present invention;

4 shows a second embodiment of a stereo microscope according to the present invention;
