DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eye optical system simulation apparatus, and more particularly to an eye optical system simulation apparatus for simulating a retinal image when an optical lens such as a spectacle lens is worn.

[0002]

2. Description of the Related Art Optical lenses such as spectacle lenses are used to maintain normal vision. Many spectacle lenses with different optical characteristics are sold. When the classification of spectacle lenses is roughly classified by optical specifications, they are classified into a single focus lens having one focus in one lens and a multifocal lens having a plurality of focuses in one lens. Further, the single focus lens is divided into a spherical lens and an aspheric lens. The design of the aspherical lens varies from manufacturer to manufacturer. Similarly, multifocal lenses are also classified into many types. For example, there are a bifocal lens, a trifocal lens, and a progressive multifocal lens, and these lenses are further subdivided.

When selecting an optical lens, a lens suitable for a wearer is selected from lenses having various optical specifications. As a judgment material in the selection, a clerk makes a selection by preparing a plurality of types of lenses having a lens power suitable for the wearer and actually wearing the lens, or a clerk of an eyeglass store listening to the request of the wearer. There was a way.

However, it is actually difficult to own a plurality of lenses having different powers suitable for the wearer according to optical specifications in an eyeglass store because of the large number of types. On the other hand, the method in which the clerk asks the wearer for his / her request and makes a selection requires skill of the clerk. Further, it is difficult for the clerk to always make an accurate judgment because the clerk cannot know what the wearer actually looks like.

[0005] In order to solve such a problem, there is an eye optical system simulation apparatus capable of simulating a retinal image when wearing spectacles or the like. First, the first eye optical system simulation apparatus traces a parallel light beam from a light source screen in an optical system such as an optical lens and a cornea, and generates a PSF.
(Point Spread Function). The PSF is a function representing how light emitted from one point on the object is distributed on the image plane. Retinal image data is calculated from the PSF and the original image data. By displaying the thus obtained retinal image data on the screen of the display device, it is possible to objectively determine how the image is viewed. As such an example, the present applicant has filed Japanese Patent Application No. 7-2693.
No. 6 has been filed.

[0006] Further advanced, a simulation apparatus for a second eye optical system which takes into account the influence of chromatic aberration of light has been considered. That is, the refractive index of an optical material such as a lens depends on the wavelength, and the shorter the wavelength, the higher the value. Therefore, PSFs at a plurality of wavelengths are obtained, and monochromatic retinal image data for each wavelength is generated from the original image data and the PSF for each wavelength. By synthesizing the monochromatic retinal image data, it is possible to simulate the retinal image including chromatic aberration. As such an example, the present applicant has filed Japanese Patent Application No.
-71502 has been filed.

On the other hand, the above-described simulation apparatus for the first eye optical system can simulate only an image in a range where the retina can be focused when the human eye is facing a certain direction. However, when the eyeglasses are actually worn, it is possible to focus an arbitrary image in a wide range by rotating the eye. Therefore, a third eye optical system simulation device capable of simulating a scene image in a range in which the human eye can be rotated and looked around has been considered.

[0008] In the third eye optical system simulation apparatus, a large light source screen capable of overlooking the whole by rotating the eye is assumed, and viewpoints arranged in a grid on the light source screen are set. PSF when looking at this viewpoint
Are obtained, and a retinal image is generated using PSFs corresponding to all viewpoints. Thereby, it is possible to simulate a scene image when the eye is turned and the surroundings are looked around. As such an example, the present applicant has filed Japanese Patent Application No. 7-71503.

[0009]

However, the effect of the chromatic aberration appears remarkably when the rotation angle is large, whereas the conventional eye optical system simulation apparatus turns the eye and looks around the periphery. It was not possible to simulate the scene image in this case in consideration of chromatic aberration.
Therefore, even if you simulate the appearance of the scene image,
The characteristics including the influence of the chromatic aberration of the optical lens could not be accurately recognized.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is an eye light capable of simulating a wide angle scene involving rotation of a human eye when wearing an optical lens such as eyeglasses, including the influence of chromatic aberration. An object of the present invention is to provide an academic simulation device.

[0011]

According to the present invention, in order to solve the above-mentioned problems, in an eye optical system simulation apparatus for simulating a retinal image when an optical lens is worn, a light source screen placed at a predetermined position is provided.

[0012]

A plurality of viewpoints are defined on a light source screen placed at a predetermined position, and the human eye rotates so that the image at the viewpoint focuses on the retina at each of the plurality of set wavelengths.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating the principle of the eye optical system simulation apparatus according to the present invention. In this simulation device, it is assumed that the light source screen is sufficiently large that the entire image cannot be seen without turning the human eye. Viewpoints arranged in a grid are set on the light source screen. Then, the original image data 1 drawn on the light source screen is set.

The image decomposing means 2 decomposes the original image data 1 into a plurality of monochromatic image data 3a to 3c for each set wavelength. The monochromatic image data 3a to 3c are image data obtained by extracting only a spectrum of a certain wavelength from the original image data 1. That is, the original image data 1
Is spectrally decomposed, and image data obtained from a spectrum of a preset wavelength is obtained at all wavelengths, thereby obtaining single-color image data 3a to 3a for each wavelength.
c is generated. The wavelength set at this time can be set arbitrarily. For example, it can be set at intervals of several nm in the wavelength region of visible light.

When the original image data 1 is drawn in a fixed color like black and white data, the shapes of the images obtained by the respective spectra when the spectrum is decomposed are all the same. In this case, the original image data 1 can be used as the monochromatic image data 3a to 3c of each wavelength without being decomposed. That is, in this case, the image decomposing means 2 becomes unnecessary.

The monochrome image data 3a generated as described above
Scene image generation units 10a to 10c corresponding to
c is provided. The scene image generation unit 10a includes a PSF (Poin) corresponding to each viewpoint set on the light source screen.
t Spread Function) Calculation units 12 to 14 are provided. For example, when the light source screen is decomposed into m in the vertical direction and n in the horizontal direction, m × n PSF calculation units are provided.

In each of the PSF calculators 12 to 14, optical system data 12c, 13c, and 14c are set in a state where the human eye is rotated so that the image at the corresponding viewpoint is focused on the retina. The optical system data 12c, 13c, 14
c is the position data of the corresponding viewpoint, the data on the optical lens, and the data on the human eye. Data relating to the optical lens includes the curvature of the convex surface, the curvature of the concave surface, and the refractive index of the lens. These data can be obtained from the design values of the lens. The data on the human eye is data on the cornea, pupil, lens, retina, rotation angle, and the like. These data are basically obtained by using a model of glustrand, and the value of the axial length or the radius of curvature of the convex surface of the cornea is determined according to the eyesight of the wearer. The refractive index of each medium at this time is the refractive index of the light of the corresponding wavelength.

PSF calculating means 12b, 13b, 14b
Is a PSF based on the optical system data 12c, 13c, and 14c.
12a, 13a and 14a are obtained. PSF 12a, 13
a and 14a are functions representing how light emitted from a certain viewpoint is distributed on the image plane. Scene image calculation means 11
Converts the corresponding single-color image data 3a into PSFs 12a and 13
The convolution integration is performed by using a and 14a to obtain monochromatic scene image data 4a.

Similarly, the other scene image generation units 10b and 10b
Also in c, monochromatic scene image data 4b and 4c are generated based on the optical system data at the corresponding wavelength. The scene image synthesizing means 5 generates the generated single-color scene image data 4a, 4a.
b and 4c are combined to generate scene image data 6. The display control means 7 displays an image obtained from the scene image data 6 on the display device 8. Thus, the entire scene that can be recognized by moving the line of sight up, down, left, and right while the influence of chromatic aberration is added is displayed on the display screen. In this manner, a simulation of a scene image including the influence of chromatic aberration can be performed.

Next, the procedure of simulation in the eye optical system simulation apparatus of the present invention will be described in more detail. First, original image data to be displayed by simulation is set. The original image data is drawn on the light source screen within a range where the focus can be achieved by rotating the human eye.

FIG. 2 shows a light source screen. A plurality of viewpoints arranged in a grid are set on the light source screen 20. The light source screen 20 is a plane perpendicular to the X axis, and has a central part on the X axis. Then, in the Y-axis direction, m (y ₁ to y ₁ )
decompose y _m), it is decomposed into n (y ₁ ~y _n) in the Z axis direction. Therefore, m × n viewpoints are provided on the light source screen. By giving light intensity at each viewpoint on the optical screen 20, original image data having an arbitrary shape is set.

The original image data is decomposed into spectra for each predetermined wavelength. The wavelengths set at this time may be three of d-line (He), F-line (H), and C-line (H), or three of e-line, F'-line, and C'-line. You may. It is also possible to decompose into more wavelengths including the above-mentioned wavelength, or to decompose into spectra at intervals of 5 nm from 380 nm to 780 nm.

Further, optical system data when the human eye looks at the light source screen while rotating is set for each wavelength. To obtain the optical system data to be set at this time, the refractive index at each wavelength of the spectacle lens is required. The refractive index of an optical lens is specified by its material, and the characteristics of the lens are generally indicated by using the Abbe number which is the reciprocal of the dispersibility. There are Abbe numbers based on the d-line and those based on the e-line. In recent years, the Abbe number based on the e-line (Hg) has been widely used, but the difference between the case based on the e-line and the case based on the d-line is the case based on the e-line. Is only slightly smaller,
The same is true in terms of the degree of dispersion.

The Abbe number ν _{d based on the} d-line is defined by the following equation.

[0025]

[Number 1] _{ν d = (n d -1)} / (n F -n C) where, n _d is the refractive index of the medium with respect to the d-line (589 nm), the medium for the n _F is the F-line (486 nm) And n _C is the refractive index of the medium with respect to the C line (656 nm).

On the other hand, the Abbe number (ν _e ) based on the e-line
Is defined by the following equation:

[0027]

[Number 2] _{ν e = (n e -1)} / (n F '-n C') where, n _e is the e line (540.07nm), n _{F 'is} F'
Line (479.99 nm), n _{C ′} is the C ′ line (643.85).
nm).

The smaller the value of the Abbe number, the larger the change in the refractive index with the change in the wavelength. Conversely, the larger the Abbe number displayed on various manufactured and sold spectacle lenses, the smaller the chromatic aberration, that is, the color shift around the lens. Generally, when used as a spectacle lens,
The Abbe number is desirably 40 or more (when d-line is used as a reference). Conversely, the effect of chromatic aberration becomes conspicuous when the lens power is 1/10 or more of the Abbe number. Have been.

From the Abbe number as described above, the refractive index of the optical lens to be simulated for an arbitrary wavelength can be calculated. Then, using the refractive index at each wavelength, optical system data is created when the human eye turns and looks at the viewpoint set on the light source screen.

FIG. 3 is a diagram showing changes in the optical system when viewing the light source screen. This figure shows a case where the rotation angle in the Z-axis direction is fixed and the angle in the Y-axis direction is changed. Here, a straight line connecting the rotation center O of the human eye and the center point of the spectacle lens is set as the reference axis 37.

(A) is an optical system for viewing the upper end of the light source screen. The human eye 30 rotates upward and the light source screen 20
Are directed straight to the viewpoint (y _m , z _i ) at the upper end. That is, it rotates upward by an angle α ₁ from the reference axis 37. Therefore, the light 36 at the upper end of the light source screen 20
a enters the spectacle lens 21 from an obliquely upward direction. The light 36a passing through the spectacle lens 21 enters the human eye, and the image is recognized. From this state, the human eye 30 becomes Y
Rotate in the negative direction of the axis.

(B) is an optical system for viewing the center of the light source screen. The human eye 30 does not rotate and faces straight toward the center of the light source screen 20. That is, the direction of the reference axis 37 and the line of sight of the human eye match. Therefore, the light source screen 20
The light 36b at the center of is vertically incident on the spectacle lens 21. The light 36b passing through the spectacle lens 21 enters the human eye, and the image is recognized. From this state, further rotation is performed in the negative direction of the Y axis.

(C) is an optical system for viewing the lower end of the light source screen. The human eye 30 rotates downward and the light source screen 20
Faces straight at the lower end of the. That is, the reference axis 3
It is turned downward by an angle α ₂ from 7. Therefore, the light 36c at the lower end of the light source screen 20 enters the spectacle lens 21 from a diagonally lower direction. The light 36c passing through the spectacle lens 21 enters the human eye, and the image is recognized.

In this way, the optical system data at all viewpoints when rotating in the Y-axis direction is obtained. Thus, when the human eye rotates, the values of various data change. For example, the distance from the spectacle lens to the cornea changes with the rotation. Also, if the spectacle lens is a multifocal lens, with a change in the position where light enters the lens,
The radius of curvature of the concave and convex surfaces also changes.

FIG. 3 shows an optical system in the case where the value of the Z axis on the optical screen is fixed and the human eye rotates vertically, and the value of the Z axis is further changed from z ₁ to z _n. By changing the optical system data, optical system data corresponding to all viewpoints can be obtained, including the case where the light source screen is rotated in the left and right directions.

Next, the optical system data when the human eye is rotated will be described in detail. FIG. 4 is a diagram showing the optical system in a state where the human eye is rotated. In this example, the user is looking at a viewpoint in a direction below the reference axis 37. The light 36 output from the viewpoint obliquely passes through the lower peripheral portion of the spectacle lens 21 and enters the human eye 30. The human eye 30 rotates and is directed straight to the viewpoint, and has a cornea 31 acting as a lens on the front surface. The pupil 32 is located behind the cornea 31 and functions to reduce the amount of incident light. Behind the pupil 32 is a crystalline lens 33 that functions as a lens.
Behind the lens 33 is the vitreous body 34, and behind it is the retina 35.

In this optical system, the radius of curvature of the convex surface and the concave surface and the refractive index are set as data relating to the spectacle lens 21. The data relating to the human eye 30 include the radius of curvature of each surface of the cornea and the lens, and the cornea 31 and the lens 3
3. The refractive index of the vitreous body 34 is set. In addition, the refractive index in the human eye 30 is obtained from a model of a glue strand, and the refractive index of the spectacle lens 21 is obtained by actually measuring. More human eyes 3
The distance between the cornea, the pupil 32, the crystalline lens 33, and the retina 35 within 0 is set. Basically, data on the human eye uses data of a model of a glustrand, and the distance to the retina or the curvature of the convex surface of the cornea is set according to the visual acuity of the human eye to be simulated.

Then, the position of the viewpoint on the light source screen is set. By performing ray tracing of light from that position, the angle θ between the light 36 incident on the spectacle lens 21 and the reference axis 37 and the rotation angle α can be obtained. In addition,
The angle θ between the light 36 and the reference axis 37 and the rotation angle α are not the same. This is because the traveling direction of the light 36 slightly changes when the light 36 passes through the spectacle lens 21.

As described above, optical system data at an arbitrary wavelength can be obtained. The optical system data is obtained for all preset wavelengths. Thus, optical system data in a state where the human eye is directed to an arbitrary viewpoint can be obtained from all viewpoints for each set wavelength.

Further, each monochromatic image data is subjected to convolution integration by the PSF obtained by the corresponding wavelength to obtain monochromatic scene image data. The light intensity distribution of the ideal image on the image plane is represented by f (y, z) and the PSF at the point (y, z).
Let p (x, y, u, v) be the point (y,
The light intensity in z) can be represented by the following equation.

[0041]

(Equation 3)

Here, p (u, v, uy, uz) is the value of the PSF at a point (uy, vz) apart from each point (u, v). A is the spreading radius of the PSF. By using this equation to determine the light intensity at a point on the retina for each rotation angle of the human eye, monochromatic scene image data can be obtained. This monochromatic scene image data is obtained for all wavelengths.

Next, all the generated single-color scene image data are synthesized. In an RGB color matching system, which is a basic color matching function, when light of a specific wavelength reaches the retina, R (700.n)
m), G (546.3 nm) and B (435.8 nm). In other words, light of any color is converted to light of three colors (R
It is possible to specify the intensity of RGB light to be replaced by GB) and to be sensed by a human.

However, in the RGB color matching system, one of the three values may be a negative value. Therefore, in general, XY using the original stimuli X, Y, and Z that can be matched by a positive additive color mixture of the original stimuli by RGB.
A Z color matching system is used. In this case, after calculating the stimulus value in the XYZ color matching system for each of the F line, the d line, and the C line,
The intensity of the RGB spectral line is obtained by converting the value into a B color matching value. That is, scene image data is created by converting each single-color scene image data into data of RGB spectral lines and adding the intensity for each coordinate value for each of the RGB spectral lines.

When the original image is separated into three colors, the images of each color are represented by R (700 nm), G
(546.3 nm) and B (435.8 nm). For example, when the color is separated into three colors of d-line, F-line, and C-line, the d-line, F-line, and C-line are G,
B and R are regarded as speckle lines. Also, e line, F 'line,
In the case of the combination of the C 'lines, the e line, the F' line, and the C 'line are regarded as G, B, and R speckle lines, respectively. Thus, when displaying the screen on the display device, the three colors are displayed on the CRT (C
(Athode Ray Tube) can be made to correspond to each dot of RGB, and the screen can be easily displayed.

The scene image data obtained as described above is a continuous display of an image projected on the retina when a person wearing glasses looks around by rotating his or her eyes. The image takes into account the effects of chromatic aberration.

In this way, it is possible to simulate an image perceived by a human when a wide range is viewed by rotating the eye in consideration of chromatic aberration. Therefore, even in the case of a multifocal lens, it is possible to accurately recognize characteristics including the influence of chromatic aberration of the lens. As a result, the spectacle wearer can easily select a lens that suits him. On the other hand, when designing or evaluating a lens of a complicated optical system such as a progressive multifocal lens, if the data of the optical system of the lens is input, the characteristics of the lens can be accurately known.

Next, hardware for performing the above-described simulation will be briefly described. FIG. 5 is a block diagram of the hardware of the workstation for performing the above simulation.

As shown in the figure, the workstation is
A processor 61, a graphic control circuit 64, a display device 65, a mouse 66, a keyboard 67, a hard disk device (HDD) 68, a floppy disk device (FD)

The processor 61 controls the entire workstation in a centralized manner. The read-only memory 62 stores a program required at the time of startup. The main memory 63 stores a simulation program and the like for performing a simulation.

The graphic control circuit 64 includes a video memory, converts the obtained scene image data into a display signal, and displays it on the display device 65. The mouse 66 is a pointing device for controlling the mouse on the display device and selecting various icons and menus.

The hard disk device 68 stores a system program and a simulation program, and is loaded into the main memory 63 after the power is turned on. In addition, simulation data and the like are temporarily stored.

The floppy disk device 69 inputs necessary data such as original image data from the floppy 69a, and saves the data to the floppy 69a as necessary. The printer device 70 is used to print out PSF, scene image data, and the like.

The magnetic tape device 71 is used for saving simulation data to a magnetic tape as required. Note that a high-performance personal computer or a general-purpose computer other than the workstation may be used.

[0055]

As described above, according to the present invention, monochromatic scene image data for each of a plurality of set wavelengths is created from image data set in a range overlookable by rotating the eye. Since a scene image is generated by combining monochromatic scene image data,
It has become possible to simulate a wide-angle scene involving rotation of a human eye when wearing an optical lens such as spectacles, including the influence of chromatic aberration. As a result, even with an optical lens having a complicated optical system such as a multifocal lens, it has become possible to objectively recognize the lens characteristics including the influence of chromatic aberration.
