Common surgical loupe magnifications of 2.5 to 3.5 times are common and up to 6 times magnification is used. Magnifications beyond the magnification of a surgical loupe are made using a surgical microscope that can be magnified 10 to 40 times.
Figure 2 is a view showing a conventional surgical microscope (HM500 model of Leica Corporation).
Leica head mounted surgical microscopes currently on the medical market are capable of dividing the path of light through a semi-transparent mirror to the optical field of view of both eyes, or generating and storing digital images through a third separate lens, but all It is an optical type that shows magnified image through lens combination, and it is hard to wear for long time operation because of its heavy weight, and the light of invisible region wavelength such as infrared ray, ultraviolet ray, etc. I can't see it directly.
Both the surgical loupe and the surgical microscope can only see magnified images in visible light. In addition, the surgical lupe is easy to wear, but the magnification is small, there is no zoom function, there is a problem that additionally requires a head-mounted light source or shadowless light. In addition, surgical microscopes are complex to install, their narrow field of view is cumbersome to use, and the equipment is heavy and bulky.
Therefore, there is a need for a surgical loupe that can zoom in on a surgical site image or enlarge the operator as desired, and a surgical loupe capable of observing an image under an infrared or ultraviolet light source as well as visible light is required.
Therefore, the problem to be solved by the present invention is to provide a head-mounted surgical magnification apparatus that can easily adjust the magnification of the surgical site to a larger magnification than before.

The
When the RGB input image is blurry or the color is not clear, conversion from the RGB color space to the YCbCr color space is performed using Equation 1 below.
Luminance (Y) is a component that expresses a light and dark degree, and color difference (C) is a component that expresses color information. The two color difference components have Cb and Cr values, where Cb is the difference between the blue (B) component and the reference value, and Cr is the difference between the red (R) component and the reference value. Since the human eye is more sensitive to the change in brightness than the change in color, one embodiment of the present invention uses only a luminance signal. In particular, the YCbCr color space is a color space obtained by separating luminance components from color information using human visual characteristics sensitive to luminance.
In addition, although an embodiment of the present invention describes the conversion of an RGB image to a YCbCr signal, it can be applied not only to YCbCr conversion coordinates but also to other color space coordinate systems such as YUV, Lab, and YCC. have.
The
In general, a blurry image has an increased overall brightness, and the brightness difference between the surrounding pixels is not distinguished. This means that the dispersion of the brightness between pixels is reduced, and this can be clearly seen by generating the luminance histogram using the luminance signal.
The average of the luminance of the blurry image is larger than that of the clear image, and the comparison of the histogram spreading from the left and the right shows that the blurry image is smaller. This means that the dispersion of the blurry image is smaller.
A subtracted luminance value is determined such that the difference between the result of subtracting the subtracted luminance value from the luminance signal of the ideal image or the luminance signal of the pre-operative image and the image input during surgery is minimized. In this case, the subtracted luminance value may be determined for each divided region.
The
The
The
The conversion equation from the YCbCr color space to the RGB color space is shown in Equation 2 below.
Subsequently, as a result of subtracting the subtracted luminance value from the input image by the
Histogram stretching extends the range between the minimum and maximum values of the histogram of an RGB image to the maximum range that the imaging device can represent. In general, 8 bits of each R, G, and B channel are extended to have a range of 0 to 255.
So far I looked at the center of the preferred embodiment for the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
In the field of science, such as biology, physics, or engineering, which utilizes an optical stereomicroscope that uses much magnification of the x2-x40 magnification, as well as the medical field, the enlargement device for head mounted surgery according to an embodiment of the present invention is utilized. It can also be applied to industrial situations, for example, in any situation where expansion is necessary, for example, in the inspection of semiconductor production processes.If the application of visible light, infrared light, and ultraviolet light is combined, the image can be obtained in a wider area than the visual confirmation. have. For example, you can view virtual video see-throughs processed through the CCD-LCD path, making digital sunglass and digital night surveillance projections better than looking directly at bright or dark light. Night vision glasses), digital telescopes, and magnifying glasses for altitude myopia correction.
