1 is a view showing a stereo microscope according to a first embodiment of the present invention.

Referring to FIG. 1, a stereoscopic microscope according to a first exemplary embodiment of the present invention includes a lens system 100 and 100a, an image sensor 200 and 200a, an image acquisition position adjusting means 300 and 300a, a signal processing unit 400 and a stereoscopic image display unit. 500 is made.

The lens system (100, 100a) is provided with two lens systems (100, 100a) for forming the left image and the right image of the subject 10 at a constant magnification, respectively, the two lens systems (100, 100a) are respectively the subject ( 10) the objective lens (110,110a) for forming the image by using the light generated from the object 10 from the side, the reflection mirror (120,120a), reflecting the image formed in the objective lens (110, 110a) Switching mirrors (130,130a) for switching the image reflected by the reflection mirrors (120,120a) left and right, and eyepieces (140,140) for transferring the image switched left and right by the switching mirrors (130,130a) to the image sensor (200,200a) a) consists of.

In addition, the reflection mirrors 120 and 120a and the switching mirrors 130 and 130a invert left and right images of the subject image formed on the objective lenses 110 and 110a, respectively, and transfer the left and right images to the eyepieces 140 and 140a, respectively. In the first embodiment of the present invention, the left and right images formed by the objective lenses 110 and 110a are reflected by 90 degrees by the reflecting mirrors 120 and 120a, and then the switching mirrors 130 and 130a. By reflecting by 90 degrees by the optical axis output from the objective lens (110,110a) and the optical axis input to the eyepiece (140,140a) parallel to each other.

However, the lens system (100, 100a) is sufficient to form and switch the left and right image of the subject 10 at a constant magnification, and transfer it to the image sensor (200,200a), the left and right image without switching A method of inverting left and right of the image signals acquired by the image sensors 200 and 200a may be used. In addition, the reflective mirrors 120 and 120a may be provided as one reflective mirror that reflects light incident from the bottom 90 degrees to the left and right in an inverted triangle shape.

Therefore, two lens systems 100 and 100a may be provided so that the left and right images of the subject 10 may be imaged in the same manner as if a person looks at the subject 10 with both eyes.

The image sensors 200 and 200a are provided with two image sensors 200 and 200a, and the left and right images formed on the lens system 100 and 100a are obtained as left eye image signals and right eye image signals, respectively. To send.

In addition, the image sensors 200 and 200a may each include a charge coupled device (CCD) and / or a complementary metal oxide semi-conductor (CMOS) device, and convert light such as an image plate and a photodiode into an electrical signal. Any sensor that can do it is possible.

The image acquisition position adjusting means (300,300a) is provided with two image acquisition position adjusting means and is located between the image sensors (200,200a) and the lens system (100,100a), respectively, the lens system (100,100a) When the images formed by the photo sensor are exposed to the image sensors 200 and 200a, it serves to adjust the position or size of the photo.

The reason for adjusting the position or size of the images that are exposed to the image sensors 200 and 200a is that the stereoscopic image display unit 500 depends on the position or size of the left and right eye images that are exposed to the image sensors 200 and 200a. Since the position or size of the images formed in the half mirror 530 of the image varies, the left eye image and the right eye image formed in the half mirror 530 are imaged to the same size at a predetermined distance on the same horizontal line to optimize the resolution. To maintain.

In addition, the image acquisition position adjusting means (300,300a) is to move the image sensor (200,200a) or the lens system (100,100a) in the X-axis, Y-axis or Z-axis or rotate around the Z (θ) By adjusting the position of the images are exposed to the image sensor (200, 200a).

In the first exemplary embodiment of the present invention, the lens systems 100 and 100a are fixed and the image sensors 200 and 200a are moved in the X-axis, Y-axis or Z-axis, or rotated around Z. Adjust the position where the image sensors 200 and 200a are exposed.

However, the image sensors 200 and 200a may be fixed, and the lens systems 100 and 100a may be moved in the X-axis, the Y-axis, or the Z-axis, or rotated around Z.

That is, it is sufficient to be able to adjust the position or size at which the images are exposed to the image sensors 200 and 200a.

A detailed description will be given with reference to FIG. 5.

The signal processor 400 converts image signals input from the image sensors 200 and 200a into image data that can be read by a display device, and outputs two image data of left eye image data and right eye image data. The apparatus may further include a control device (not shown) for receiving the image signals therein and a graphic board (not shown) for converting the image signals into image data.

The stereoscopic image display unit 500 receives the image data converted by the signal processing unit 400 to create a stereoscopic image, and the first display device 510, the second display device 520, and the half mirror 530. And an image inversion circuit 540.

The display devices 510 and 520 are formed by attaching polarization filters 512 and 522 having the same polarization angle to 45 degrees on the front of the display panels 511 and 521, respectively.

In addition, the display panels 511 and 521 may be provided as an LCD liquid crystal panel, a plasma display panel (PDP) panel, or an organic light emitting diode (OLED) panel. In the first embodiment of the present invention, the display panels 511 and 512 may be provided. All were equipped with LCD liquid crystal panel.

In general, the LCD liquid crystal panel has a polarizing filter attached to the front and is manufactured as one display device. Therefore, the polarizing filter does not need to be attached again. However, since the polarizing filter is not attached to the PDP panel or OLED panel, the polarizing filter should be attached to the front. .

In addition, the display devices 510 and 520 may be manufactured by attaching a polarization filter having a polarization angle of 135 degrees to the front of the display panels 511 and 521.

In addition, the first display device 510 and the second display device 520 may be manufactured by attaching a polarization filter having a front polarization angle of 90 degrees, 0 degrees, 0 degrees, or 90 degrees, respectively.

As a result, the polarization angle of the polarization filter is sufficient when the left and right images are simultaneously formed in the half mirror 530 such that the polarization angles of the images form 90 degrees to each other.

However, even though the polarization angles of the left eye image and the right eye image formed on the half mirror 530 are not necessarily 90 degrees, the left eye image and the right eye image having different polarization angles are formed on the half mirror 530 to separate the polarization angles. If the polarizing glasses 20 are visible, the viewer can observe the stereoscopic image.

The first display apparatus 510 receives left eye image data from the signal processor 400 and displays a left eye image.

The second display apparatus 520 receives the right eye image data from the signal processor 400 and displays the right eye image, and the lower front portion forms an edge with the front lower portion of the first display apparatus 510 at a predetermined angle. . Preferably it is installed at 90 degrees. However, the predetermined angle may be changed according to the refractive index and the reflectance of the half mirror 530 provided between the display devices 510 and 520.

In addition, the right eye image may be displayed on the first display apparatus 510 and the left eye image may be displayed on the second display apparatus 520.

Therefore, the observer can observe a stereoscopic image by wearing only the left eye image with the left eye and only the right eye image with the right eye by wearing polarization glasses 20 having different polarization angles of the left and right lenses.

In the first embodiment of the present invention, the image of the first display apparatus 510 is transmitted by the half mirror 530 and the image of the second display apparatus 520 is reflected. However, the image of the first display device 510 may be reflected and the image of the second display device 520 may be transmitted.

The half mirror 530 is also called a translucent mirror as one mirror transmits light and the other reflects light.

In addition, the display apparatuses 510 and 520 maintain a constant angle between the display apparatuses 510 and 520.

However, the angle of 45 degrees may be changed according to the refractive index and the reflectance of the half mirror 530 and the left and right eye images displayed by the display apparatuses 510 and 520 may be simultaneously formed on the half mirror 530 without being distorted. It is enough if you can.

The image reversing circuit 540 inverts the image of the display apparatus for illuminating the image on the reflective surface of the half mirror 530 among the display apparatuses 510 and 520 from side to side.

The reason is that since the reflection surface of the half mirror 530 is like a mirror, the image of the display device that is illuminated is inverted in left and right directions.

 In the first exemplary embodiment of the present invention, since the right eye image of the second display apparatus 520 is reflected by the half mirror 530, the image inversion circuit 540 right and left the right eye image of the second display apparatus 520. Invert to

Accordingly, the left and right eye image signals generated by the image sensors 200 and 200a are made into a stereoscopic image by the stereoscopic image display unit 500 and the observer is attached to the half mirror 530 by wearing polarized glasses 20. By looking at the stereoscopic image, the observer can observe the image of the subject 10 as a 3D stereoscopic image.

The stereoscopic microscope according to the second exemplary embodiment of the present invention can realize a stereoscopic image simply without the image inversion circuit 540.

In general, the LCD panel 611 has a front polarizing filter 611c attached to the front of the LCD liquid crystal panel 611b and a rear polarizing filter 611a attached to the rear.

In addition, when the LCD panel 611 is viewed from the front, the front and rear polarization angles of the front and rear polarizations are 45 degrees, 135 degrees, and 135 degrees by the front polarization filter 611c and the rear polarization filter 611a, respectively. 45 degrees, 0 degrees, 90 degrees, or 90 degrees, 0 degrees to make 90 degrees to each other.

In addition, if the rear case and the backlight unit (BLU: Backlight unit) are removed due to the characteristics of the LCD, it is possible to see the transmission image in which the front and the left and right are reversed.

As shown in FIG. 3, the backlight 612 is separated from the third display apparatus 610 by using the structure of the LCD panel as described above. After the rotation, the fourth display device 620 is manufactured by inverting the left and right directions of the image by combining the backlight 612.

That is, the rear of the LCD panel 611 of the third display device 610 is the front of the LCD panel 621 of the fourth display device 620.

In addition, when the front and rear polarization angles are 45 degrees, 135 degrees, 135 degrees, and 45 degrees, respectively, the front polarization angle of the third display apparatus 610 and the front polarization angle of the fourth display apparatus 620 are also the same. Since the half mirror 530 has a three-dimensional image having a polarization angle of 90 degrees to each other.

However, when the front and rear polarization angles are 0 degrees, 90 degrees, 90 degrees, or 0 degrees, respectively, the front polarization angle of the third display apparatus 610 and the front polarization angle of the fourth display apparatus 620 are the same. However, while forming 90 degrees, the left and right images having the polarization angle of 90 degrees are simultaneously formed in the half mirror 530.

Accordingly, the image and polarization of the third display apparatus 610 are transmitted to the half mirror 530, and the image and polarization of the fourth display apparatus 620 are reflected and inverted. It can produce the same effect as 500).
