Description

Binocular stereo microscope with stereoscopic representation

The present invention relates to a binocular stereo microscope, and more specifically, to a binocular stereo microscope capable of stereoscopic image representation capable of outputting a stereoscopic image when the binocular stereo microscope image is output through an image output device. It is about.

A general binocular stereoscopic microscope simultaneously observes one observation at a different angle with two eyes of a human, so that the images of the observations observed at that angle are respectively lifted by two human eyes and merged into one image in the brain.

Therefore, when viewing an observation through a binocular stereoscopic microscope, the observer can observe the observation in a three-dimensional image, thereby observing a more precise and realistic image.

In addition, in order to allow multiple people to simultaneously observe the shape of the observation object observed through the binocular stereo microscope, the CD is attached by changing the optical path of any one of the optical path input to the observer's eyes through the binocular stereo microscope. Charge Coupled Device (CCD) Enables input to a camera.

Therefore, one of the images input to the observer's left and right eyes through the set optical path is input to the CD camera.

Therefore, an image input by the CD element attached to the CD camera is imaged and converted into a corresponding electric video signal.

Therefore, the electrical image signal output from the CD element is processed into an image signal usable by an operation of an electronic circuit such as a signal processing unit built in the CD camera, and is captured by the CD element with an output device such as a liquid crystal display device. Since the image signal is output, the image observed through the binocular stereo microscope is displayed so that multiple people can observe it at the same time.

However, at this time, the image signal corresponding to the left and right is not output to the output device at the same time, and only one image signal corresponding to the left or right is output to the corresponding output device, so the image output from the output device is three-dimensional It is not an image but a one-dimensional planar image.

Therefore, as when observing an observation using a binocular stereoscopic microscope, it cannot be observed in a vivid three-dimensional image, so it is difficult to observe the exact characteristics and shape of the observation, and to enjoy a realistic one-dimensional image. There is a problem that must be done.

Therefore, an object of the present invention is to solve the above-described problems, and it is possible to display an image output through a binocular stereo microscope as a three-dimensional stereoscopic image through an image output device, so that several people can simultaneously display a three-dimensional stereoscopic image. To provide a binocular stereo microscope capable of expressing a stereoscopic image to observe the image output through the microscope.

It is connected to the output terminal of the image synthesizing unit 4 and is driven by a driving circuit (not shown), and is applied to the right image signal R 'and the left image signal L' alternately applied by the image synthesizing unit 4. The liquid crystal display 5 alternately displaying the left image and the right image in one frame;

The image output from the liquid crystal display 5 may be divided into an image corresponding to the right eye and an image corresponding to the left eye, and then output. The image displayed on the liquid crystal display 5 may be recognized as a 3D stereoscopic image. It consists of a lenticular lens unit (6).

The right / left light sources 100 and 200 are mounted on the right / left light sources 1001 and 2001 and the optical axes of the right / left light sources 1001 and 2001 and are irradiated from the right / left light sources 1001 and 2001.

In addition, the image synthesizing unit 4 exchanges the electric right image signal R ′ output from the right CD optical system 312 and the electric left image signal L ′ output from the left CD optical system 322. By synthesizing, the right image signal R 'and the left image signal L' are alternately outputted as data signals of the liquid crystal display unit 5, which is the same as or similar to the known image signal synthesizing apparatus. It can be implemented using technology.

Since the above-described configuration is composed of the optical system for the right eye and the left, which have the same configuration and perform the same function, there are two identical configurations.

Therefore, in the operation description according to the embodiment of the present invention, only the operation and function of the optical system corresponding to the left eye will be described.

Operation and action of the binocular stereo microscope capable of stereoscopic image representation according to the embodiment of the present invention by the above configuration is as follows.

When the power required for the operation of each device is supplied to observe the observation placed on the stage (S), the light source (1001, 2001) of the right / left light source (100, 200) is activated to a certain amount of light to the stage (S) Investigate

The light irradiated from the light sources 1001 and 2001 is collected by the right / left condenser lenses 1002 and 2002 mounted on the optical axis, and then by the right / left sliding switch mirrors 11 and 21 to the stage S. Reflected in the direction of) to illuminate the stage (S), it is possible to image the observation placed on the stage (S).

When the light of the light source is reflected to the stage S by the operation of the right / left slide type switching mirrors 11 and 21 as described above, the right / left objective lens units 10 and 20 are placed on the stage S. The water phase is lost. In this case, the second lens parts 102 and 202 and the third lens parts 103 and 203 may move in the front / rear direction of the optical axis, and may be imaged by a set magnification. The image formed by the right and left objective lens portions 10 and 20 passes through the right and left slide type switching mirrors 11 and 21, and by the right and left eyepiece portions 13 and 23, a binocular stereo microscope is used. It is input to the left and right eyes of an observer.

Therefore, the observer combines the images of the observations input to the left and the right, respectively, in the head to synthesize one image.

At this time, since the left and right images are respectively input, the image actually recognized by the observer is a three-dimensional stereoscopic image.

Observation of the observation through a binocular stereoscopic microscope as described above is the same or similar to the operation of a conventional binocular stereoscopic microscope.

However, the image formed through the right / left eyepieces 13 and 23 is input to the mounted right / left CDs 311 and 321, respectively, to capture the input image, respectively, and to right / left After converting the electric right image signal (R) and the left image signal (L) corresponding to the image formed through the eyepieces (13, 23) to the right / left CD optical system (312, 322) Is output.

The image signals inputted to the right / left CD optical systems 312 and 322 are converted into available right image signals R 'and left image signals L' by an operation of a built-in signal processing device, and the like, to synthesize images. Output to negative (4).

Therefore, the image synthesizing unit 4 synthesizes each of the right and left image signals R 'and L' that are output from the right and left CD optical systems 312 and 322, respectively, and the right image signal R '. And the left image signal L 'are alternately present, and output to the liquid crystal display 5 so that several people can simultaneously observe the observation on the stage S observed by the binocular stereo microscope.

The image information output to the liquid crystal display unit 5 is data output from each of the mounted CD optical systems 312 and 322 after electrically converting the image output by the operation of the binocular stereo microscope as in the embodiment of the present invention. If necessary, the signal output from the binocular stereo microscope may be signal processed, and then data stored in a memory device such as random access memory (RAM) may be used.

By the operation of the image synthesizing unit 4, the synthesized signals are sequentially arranged so that the right image signal R 'and the left image signal L' are alternately present on one screen. In order to display the image signal L 'alternately on the liquid crystal display 5, it is applied as a data signal.

Therefore, as shown in FIG. 3, the liquid crystal display unit 5 uses the data corresponding to the left / right image signals L 'and R' corresponding to one frame. R'L'R'L'R'L'R'L'R '... Each pixel is sequentially displayed in order.

The left and right image signals L 'and R' are named as left and right image signals L 'and R' for convenience in order to represent an image formed in the left and right eyes of a human in a stereoscopic principle. The image signal L 'is an image corresponding only to the left side of the subject, and the right image signal R' is not an image corresponding only to the right side of the subject.

As described above, the left / right image signals L 'and R' corresponding to one frame are on the liquid crystal display unit 5. R'L'R'L'R'L'R'L '... As shown in order, the right image signal R 'and the left are displayed alternately by the respective convex lens surfaces of the lenticular lens unit 6 mounted so that the display surface of the liquid crystal display unit 5 becomes the focal plane. The image signal L 'is separately input to a field of view of several observers, not shown.

Therefore, the image signals R and L output from the binocular stereo microscope are separated by the lenticular lens unit 6 into the right image signal R 'and the left image signal L', respectively, to face the liquid crystal display unit 5. Since it is input to the observer's eye, the observer synthesizes the right image signal R 'and the left image signal L' which are respectively input to the left eye and the right eye, so that the binocular entity is a three-dimensional stereoscopic image. The shape, shape, and the like of the objects observed by the microscope can be appreciated.

3 and 4 attached to the three-dimensional principle by the lenticular lens as described above.

The lenticular lens is a flat convex cylindrical lens group divided into sections for separating the right image signal R and separating the left image signal L in one cylinder, as shown in FIG. 4. Continuously projecting images of different directions from the back side (focal plane) of the, as shown in the accompanying Figure 3, by separating the images with different directions and outputs to the left and right eyes of the observer, respectively, the observer As the user sees the images with different directions through the right eye and the left eye, respectively, the user feels a three-dimensional image.

As described above, the state observed using a binocular stereo microscope is output through an image display device connected to the outside, and when several people observe the observation state of the microscope together, the right and left images are respectively operated by the operation of the lenticular lens. Since it is separated and output to the image display device, not only a user who uses the binocular stereo microscope but also those who observe the image output through the image display device can observe the state of the observation object in a three-dimensional stereoscopic image.

As described above, since the image output through the binocular stereo microscope is output to the external image display device as a three-dimensional image, the effect of accurately observing the state of the observation occurs.
