For the purpose of facilitating an understanding of the embodiments of the present application, reference will now be made to the following description of specific embodiments, taken in conjunction with the accompanying drawings, which are not intended to limit the embodiments of the application.
Example 1
The present embodiment provides an image presentation method, referring to fig. 1 and fig. 4 to 9.
A region of the first image within a field angle at a first observation distance is acquired.
The first image comprises a static image and a dynamic image, and the dynamic image can obtain the static image frame by frame in a decoding mode.
The angle of view is the angle at which the head can see the limit of the range without rotating the eye while the head remains stationary. The range from the limit seen upward in the vertical direction to the limit seen downward is the vertical field angle, and the range from the limit seen leftward in the horizontal direction to the limit seen rightward is the horizontal field angle. The angles of view of different persons are different, the angles of view range from 0 degrees to 35 degrees, and the corresponding images are formed in the foveal imaging area. Further preferably, the angle of view is in the range of 0 ° -10 °.
The first observation distance is such that the first image at least partially exceeds the field of view angle and a range of field of view angles is determined. A first predetermined area is arranged on the periphery of the area in the angle of view, and the other areas except the first predetermined area on the first image are second predetermined areas.
In one implementation of this embodiment, the region of the first image within the field angle at the first observation distance may be determined and acquired by: the first image is acquired, the display content of the first image is not limited, the first image can be a video image or a static picture, the size of the first image is not excessively limited, and the length of the first image is only required to be longer than the distance from the leftmost side of the left eye to the rightmost side of the right eye, and the height of the first image is longer than the distance from the uppermost side of the eye to the bottommost side of the eye. And adjusting a first observation distance to enable at least part of the first image to be located at the periphery of the area in the view angle, setting a first preset area at the periphery of the area in the view angle, and enabling other areas except the first preset area on the first image to be second preset areas.
Further, the first image is an enlarged image via a first optical system, the image having a first distance. The first optical system includes: a display 1, a spectroscope 2 and a concave reflector 3; the optical path generated by the first optical system includes: the light emitted via the display 1 is transmitted via the beam splitter 2 to the concave mirror 3, and an enlarged image is formed by the concave mirror 3 to be transmitted into the eye of the observer.
In one implementation of this embodiment, the first optical system is disposed within a tele-image display device. Referring to fig. 7, the display 1, the convex lens, the concave reflecting mirror, and the beam splitter 2 form an optical path. The display 1 is arranged as a light source between the beam splitter 2 and the concave reflecting mirror, and is preferably integrally lower than the lower surfaces of the beam splitter 2 and the concave reflecting mirror so as not to affect the optical path between the beam splitter 2 and the concave reflecting mirror.
The display 1 is arranged below the convex lens. The convex lens has an outer surface that is convex. One of the outer surfaces of the convex lens opposite to or far from the display 1 is convex, in the specific embodiment, a bottom surface, and the other is a plane; the convex outer surface, when aligned with the concave mirror along a predetermined direction, coincides entirely with the contour of the reflective surface. In this arrangement, the distortion of the image caused by the precision of design and processing of the concave mirror can be counteracted, since the human eye is very sensitive to the observation of the video, the slight distortion very affects the observation, and the distortion caused by the convex lens and the concave mirror can be counteracted with each other in practice by the complementary arrangement of the convex lens and the concave mirror, thereby avoiding the distortion of the image.
Further, the center point of the display 1 is disposed on the main optical axis of the convex lens and within the focal length of the convex lens, thereby forming a second virtual image a of the display 1 that is enlarged upright on the side of the convex lens close to the display 1.
The beam splitter 2 is an optical device of the prior art and is designed primarily by the surface in contact with the light so that a portion of the light directed towards said surface is transmitted and another portion is reflected. The proportion of incident light rays and reflected light rays at different angles can be adjusted by adjusting the light rays with different proportions to achieve reflection and light ray transmission with different proportions through setting the microstructure of the surface. This is a common optical component in the prior art and thus its microstructure is not developed in detail in this embodiment.
When the light emitted from the display 1 irradiates the inner surface of the beam splitter 2, the beam splitter 2 reflects a part of the light of the display 1, and the other part of the light is transmitted through the beam splitter 2. The reflected light is in this embodiment directed towards a concave mirror behind the beam splitter 2, whereas the transmitted light is emitted upwards from said beam splitter 2.
In addition, a part of light emitted from the display 1 passes through the beam splitter 2 and reaches the beam splitter 2 for the first time, and then is transmitted out from the beam splitter 2 under the beam splitting action of the beam splitter 2, so that a part of brightness is weakened, and a part of light after the reflecting action of the concave reflector is reflected to the inner space and is not transmitted out when passing through the beam splitter 2 for the second time, so that the brightness of the light injected into eyes of an observer is further reduced, and the effect of protecting vision is played.
In this case, the virtual image a 'of the display 1 formed in the beam splitter 2 needs to be less than the focal length of the concave mirror, i.e. within the focal point F of the concave mirror, from the concave mirror, so that when the virtual image a' is re-imaged a in the concave mirror, an enlarged, upright virtual image is ensured for viewing by the viewer.
Preferably, in order to prevent distortion of the image of the display 1, on the one hand, the processing precision of the respective optical devices needs to be high, more importantly, the virtual image a' formed by the display 1 in the beam splitter 2 is parallel to the focal plane of the concave reflecting mirror as a whole, and even more preferably, the center of the virtual image formed by the display 1 in the beam splitter 2 is located on the main optical axis of the concave reflecting mirror. In this way the virtual image presented by the display 1 is symmetrically distributed with respect to the main optical axis of the concave mirror, facilitating the symmetrical display of the image.
It is further preferred that a first line connecting the center of the display 1 with the center of the beam splitter 2, and a line connecting the center of the concave reflecting mirror with the center of the beam splitter 2 are second lines, the first line and the second line being symmetrical with respect to a perpendicular line along the surface of the beam splitter 2. In this way, the display 1 can be aligned with the center of the beam splitter 2, and the center of the beam splitter 2 is aligned with the center of the concave mirror, so that the widths of the beam splitter 2 and the concave mirror can be effectively utilized to meet the display size requirement.
By setting the light path in the far-image display device, the first image is imaged in the far-image display device to be upright, amplified and provided with a virtual image with a certain distance. Further, the distance of the virtual image from the human eye enables the user to clearly see the virtual image, so that the user can avoid that the distance is close, and the micro-stimulus image does not stimulate the eye to generate traction force for attempting to shorten the axis of the eye, and in addition, the distance is far, the focus of the virtual image is placed on the front side of the retina, and the influence of peripheral defocus on the eye is weaker than the influence generated by the focus falling on the front of the retina.
That is, the first image is displayed on the display 1, a part of the light emitted from the display 1 is emitted to the concave reflective mirror 3 through the beam splitter 2, and then an enlarged upright virtual image is formed by the concave reflective mirror 3, and the virtual image is the second image. A third predetermined area and a fourth predetermined area are arranged on the second image, the third predetermined area corresponds to the first predetermined area, and the fourth predetermined area corresponds to the second predetermined area.
The far-image display device further comprises a display screen, wherein in the far-image display device, the display screen is the spectroscope 2, and a user views an imaging result based on the first image through the display screen. When a user views the display screen, the imaging distance of the second image needs to be adjusted according to different eye conditions of different users, and the second image seen by different users needs to be a clear image. In addition, the distance between the second image and the display screen is a first image distance, and the first image distance can be adjusted but does not change after being determined. The second image can not affect eyes because the image seen by the user is clear, and the micro-stimulation effect on eyes is carried out only by superposing the images, so that the comfort level of watching is improved, the eyes are used for a long time, and the burden on the eyes is avoided, so that the using endurance is reduced. In addition, the method is also suitable for users with myopia, and the users with myopia can wear glasses for watching. The first image distance is unchanged after the determination, so that the viewing distance of the user is fixed, and the effect of continuous stimulation is achieved.
Acquiring a superimposed image based on the microstimulation image; the microstimulatory image and the overlay image comprise, viewing the overlay image using a viewing system having a first diopter, having substantially the same vision as viewing the microstimulatory image using a viewing system having a second diopter; wherein the second diopter is greater than the first diopter.
The viewing system having a first diopter includes: the observer's eyes together form an observation system having a first diopter, or the observer's eyes and the observer's fitted eyeglasses. The viewing system having a second diopter includes: the eyes of the observer and the device with a certain diopter arranged in front of the eyes are used as an observation system with a second diopter, or the eyes of the observer, glasses matched with the observer and the device with a certain diopter arranged in front of the glasses form an observation system with a second diopter.
Having substantially the same visual effect has several cases: the method of the present embodiment is targeted, and a series of measurements are made for the eye condition of an individual observer to obtain a suitable device with a certain diopter. The device enables an individual observer to observe the superimposed image using an observation system having a first diopter to have the same visual result as an observation system using a second diopter to observe the microstimulated image, i.e. the effect of the presentation of the images seen by the observer in both environments is substantially the same. Finally, a series of parameters which are targeted and personalized and suitable for individual watching and have good effects are obtained, and the length of an eye axis is shortened through peripheral defocus by adjusting the parameters, so that myopia is prevented or even treated.
The method involved in yet another scenario is generic and generalized and is not directed to an independent observer. Observers having the same or similar nature of eye condition are classified into a class according to the eye condition, and the vision level of a standard observer in this class will represent the eye condition of that class to obtain a device of a certain diopter suitable for use with a standard observer in this class according to the eye condition of the standard observer to be suitable for use with other observers in the class to which the standard observer belongs. The standard observers are representative of the average level of vision of such observers such that the diopters of the lenses to which the standard observers correspond are acceptable and acceptable to other observers of the same genus.
Further, the device with a certain diopter may be a lens, that is, the lens with a certain diopter is arranged in front of the eyes or the glasses, so that the observed micro-stimulus image has a certain ambiguity, and the micro-stimulus image with the ambiguity is further considered to fall on the front side of the retina by the brain, so that the eye can see clearly, and the force for shortening the axis of the eye is generated, so as to prevent myopia or relieve the degree of myopia.
Still further, the diopter of the lens is 0.5 D.ltoreq.x.ltoreq.1.5D.
The superimposed image has substantially the same visual effect as the image of the microstimulatory image through the x-lens. Preferably, x is 0.5D-1.5D. The superimposed image has a certain degree of ambiguity relative to the microstimulation image, the superimposed images with different degrees of ambiguity need to be stored, and as the eye conditions of different observers are different, the different conditions are matched with the images which penetrate through the diopter lens, and the images are taken out and displayed in a lookup table mode when the image processing device is used. In addition, during the matching process, observers with myopia can be matched based on the condition after wearing glasses.
In order to make the superimposed image and the image obtained by the micro-stimulus image with the diopter x through the lens have basically the same visual effect, a lens with a certain diopter can be placed in front of a camera or other equipment capable of shooting, after the micro-stimulus image is placed on the lens, the camera shoots the micro-stimulus image passing through the lens, and the obtained image is continuously detected and modified through a later test, so that a visual effect of an observer when observing the superimposed image can be achieved when the observer is looking at the image obtained by the lens with the diopter x. In addition, the adjustment of the blur degree may be directly performed on the microstimulated image to obtain a superimposed image, so long as the visual effect of the superimposed image viewed by an observer is ensured to be the same as that of an image obtained through a lens with refractive power x.
It should be noted that, referring to fig. 4 and fig. 5, when there is only one pattern in the microstimulation image, and there is more than one pattern in the superimposed image, referring to fig. 6, the patterns in the microstimulation image have the same visual effect after being observed through the lens, and the visual effect of one pattern in the superimposed image is the same. Since the superimposed image includes a plurality of images obtained by simply transforming the microstimulation image, the number of patterns in the superimposed image is not equal to the number of patterns in the microstimulation image, which will be described in advance.
A superimposed image is derived based on the microstimulated image, including but not limited to a first process, a second process, and a third process. The first process includes a microstimulation image with a certain degree of blur obtained after the microstimulation image is transmitted through a lens with a certain diopter. The second process performs simple conversion including conversion processes that do not affect the display content thereof, rotation, symmetry, and the like, on the basis of the first process. The third processing includes that a plurality of microstimulation images with the same ambiguity are annularly arranged, and further, the arrangement can be that the images obtained after the first processing are directly annularly arranged, or that slightly different images after the second processing are annularly arranged. That is, the images which are annularly arranged may be the same image or may be different images which are obtained by simply transforming one image.
According to different properties of the micro-stimulus image, the superimposed image can be obtained by the micro-stimulus image after the first treatment or after the first treatment, the second treatment and the third treatment.
In a specific implementation manner of this embodiment, the microstimulation image is an image in a ring shape as shown in fig. 4, and the microstimulation image is subjected to only a first process to obtain a superimposed image.
The microstimulated image includes a pattern formed according to a predetermined contrast of light and dark.
In yet another implementation of this embodiment, the microstimulation image is the image shown in fig. 5. And performing the first processing, the second processing and the third processing on the microstimulation image to obtain a superposition image. Further, the micro-stimulus image includes a white area having a symmetrical structure in a circular shape and a black area having a symmetrical structure except for the white area, for example, a black-and-white cross pattern in a circular shape, as shown in fig. 5. So arranged as to have a better microstimulation effect. Firstly, the microstimulated image with a certain blur obtained by the microstimulated image through a lens with diopter x is stored, and a plurality of third images with different blur are needed to be stored because x has a certain range. And then, obtaining a plurality of deformed images with the same ambiguity by rotating and/or symmetrically and the like in a transformation form, and arranging the deformed images. The arrangement mode comprises that a plurality of third images are arranged in a central symmetry mode; the plurality of images are arranged in a central symmetry and an axial symmetry mode, the distances between the adjacent third images are the same, and the distances between the third images and the positions of the central points are the same, namely the plurality of third images are annularly surrounded to form a superimposed image.
Presenting the superimposed image in a manner that covers the first predetermined area, comprising: covering the superimposed image at a position corresponding to the first predetermined region of the first image; or the superimposed image replaces image content at a corresponding location within the first predetermined area of the first image.
The first preset area corresponds to an area with an angle of view of 6-23 degrees, namely, a fovea which is imaged at 6-23 degrees. Preferably, the angle of view of the first predetermined area is 6 ° -15 °.
In one implementation of the present embodiment, the first image is presented on the display 1, a second image is obtained by the first optical system, and likewise, the superimposed image replaces the image content at a corresponding position within the first predetermined area of the first image, so that an enlarged, upright image of the superimposed image is displayed within the third predetermined area on the second image. The image with a certain ambiguity and a certain distance is presented in the peripheral defocusing area of the observer through the arrangement, the ambiguity stimulates the brain to generate a signal that the peripheral presented image is far away from the retina and the landing point is in front of the retina, meanwhile, the second superimposed image is far away through the action imaging of the light path, and the influence of the ambiguity on the brain is combined, so that the retina generates forward moving force to enable the peripheral image to be presented on the retina as much as possible to be clearly viewed, the effect of shortening the eye axis is further realized, and myopia can be prevented or even treated to a certain extent.
Further, the display 1 is subjected to a process of superimposing the first image and the superimposed image before displaying. For example, the superimposed image is first displayed instead of the image at the corresponding position of the first image, if the first image is a dynamic image, the dynamic image is further decoded into a still image frame by frame, then the superimposed image is used to replace the content corresponding to the first predetermined area in the still image, and the dynamic image which is presented by the first image and the superimposed image in a combined manner is output.
In yet another implementation of the present embodiment, the superimposed image is disposed between the magnified image and the observer to cover image content at a corresponding location within a third predetermined area of the magnified image. For example, the superimposed image may be disposed in the optical path as long as the third predetermined region of the enlarged image can be blocked without affecting the final presentation effect. Further, the superimposed image is illustratively presented on an opaque carrier of paper or plastic or the like, for example, the tele-graphic display device, which is provided on the display screen of the tele-graphic display device to cover the third predetermined area of the second image presented on the display screen. The peripheral defocus micro-stimulus amount is formed by the arrangement, the superimposed image has a certain degree of ambiguity, so that the brain generates signals with far image distance presented by the periphery, the retina is enabled to have forward approaching force to enable the peripheral image to be presented on the retina as much as possible so as to be clearly watched, the effect of shortening the eye axis is achieved, and myopia can be prevented or even treated to a certain extent.
In addition, in other implementations, by way of example, when a person views a video or other first image through a mobile phone, a television or a projection, and a paper printed with the superimposed image is covered in the first predetermined area of the first image to cover the content in the area, the effect of shortening the eye axis can be achieved to some extent, according to the situation of eyes of the person. Thus, methods similar to those mentioned above are also within the scope of the present disclosure.
The final rendered image through the above steps is shown with reference to fig. 8 and 9.
Example 2
The present embodiment provides an image presentation apparatus, referring to fig. 2 and fig. 4 to 9.
The image presentation device comprises an area acquisition module, a superposition image acquisition module and a presentation module.
The region acquisition module is used for acquiring a region in a field angle of the first image at a first observation distance.
The first image comprises a static image and a dynamic image, and the dynamic image can obtain the static image frame by frame in a decoding mode.
The angle of view is the angle at which the head can see the limit of the range without rotating the eye while the head remains stationary. The range from the limit seen upward in the vertical direction to the limit seen downward is the vertical field angle, and the range from the limit seen leftward in the horizontal direction to the limit seen rightward is the horizontal field angle. The angles of view of different persons are different, the angles of view range from 0 degrees to 35 degrees, and the corresponding images are formed in the foveal imaging area. Further preferably, the angle of view is in the range of 0 ° -10 °.
The first observation distance is such that the first image at least partially exceeds the field of view angle and a range of field of view angles is determined. A first predetermined area is arranged on the periphery of the area in the angle of view, and the other areas except the first predetermined area on the first image are second predetermined areas.
In one implementation of this embodiment, the region of the first image within the field angle at the first observation distance may be determined and acquired by: the first image is acquired, the display content of the first image is not limited, the first image can be a video image or a static picture, the size of the first image is not excessively limited, and the length of the first image is only required to be longer than the distance from the leftmost side of the left eye to the rightmost side of the right eye, and the height of the first image is longer than the distance from the uppermost side of the eye to the bottommost side of the eye. And adjusting a first observation distance to enable at least part of the first image to be located at the periphery of the area in the view angle, setting a first preset area at the periphery of the area in the view angle, and enabling other areas except the first preset area on the first image to be second preset areas.
Further, the first image is an enlarged image via a first optical module, the image having a first distance. The first optical module includes: a display 1, a spectroscope 2 and a concave reflector 3; the optical path generated by the first optical system includes: the light emitted via the display 1 is transmitted via the beam splitter 2 to the concave mirror 3, and an enlarged image is formed by the concave mirror 3 to be transmitted into the eye of the observer.
In one implementation of this embodiment, the first optical module is disposed within a tele-image display device. Referring to fig. 7, the display 1, the convex lens, the concave reflecting mirror, and the beam splitter 2 form an optical path. The display 1 is arranged as a light source between the beam splitter 2 and the concave reflecting mirror, and is preferably integrally lower than the lower surfaces of the beam splitter 2 and the concave reflecting mirror so as not to affect the optical path between the beam splitter 2 and the concave reflecting mirror.
The display 1 is arranged below the convex lens. The convex lens has an outer surface that is convex. One of the outer surfaces of the convex lens opposite to or far from the display 1 is convex, in the specific embodiment, a bottom surface, and the other is a plane; the convex outer surface, when aligned with the concave mirror along a predetermined direction, coincides entirely with the contour of the reflective surface. In this arrangement, the distortion of the image caused by the precision of design and processing of the concave mirror can be counteracted, since the human eye is very sensitive to the observation of the video, the slight distortion very affects the observation, and the distortion caused by the convex lens and the concave mirror can be counteracted with each other in practice by the complementary arrangement of the convex lens and the concave mirror, thereby avoiding the distortion of the image.
Further, the center point of the display 1 is disposed on the main optical axis of the convex lens and within the focal length of the convex lens, thereby forming a second virtual image a of the display 1 that is enlarged upright on the side of the convex lens close to the display 1.
The beam splitter 2 is an optical device of the prior art and is designed primarily by the surface in contact with the light so that a portion of the light directed towards said surface is transmitted and another portion is reflected. The proportion of incident light rays and reflected light rays at different angles can be adjusted by adjusting the light rays with different proportions to achieve reflection and light ray transmission with different proportions through setting the microstructure of the surface. This is a common optical component in the prior art and thus its microstructure is not developed in detail in this embodiment.
When the light emitted from the display 1 irradiates the inner surface of the beam splitter 2, the beam splitter 2 reflects a part of the light of the display 1, and the other part of the light is transmitted through the beam splitter 2. The reflected light is in this embodiment directed towards a concave mirror behind the beam splitter 2, whereas the transmitted light is emitted upwards from said beam splitter 2.
In addition, a part of light emitted from the display 1 passes through the beam splitter 2 and reaches the beam splitter 2 for the first time, and then is transmitted out from the beam splitter 2 under the beam splitting action of the beam splitter 2, so that a part of brightness is weakened, and a part of light after the reflecting action of the concave reflector is reflected to the inner space and is not transmitted out when passing through the beam splitter 2 for the second time, so that the brightness of the light injected into eyes of an observer is further reduced, and the effect of protecting vision is played.
In this case, the virtual image a 'of the display 1 formed in the beam splitter 2 needs to be less than the focal length of the concave mirror, i.e. within the focal point F of the concave mirror, from the concave mirror, so that when the virtual image a' is re-imaged a in the concave mirror, an enlarged, upright virtual image is ensured for viewing by the viewer.
Preferably, in order to prevent distortion of the image of the display 1, on the one hand, the processing precision of the respective optical devices needs to be high, more importantly, the virtual image a' formed by the display 1 in the beam splitter 2 is parallel to the focal plane of the concave reflecting mirror as a whole, and even more preferably, the center of the virtual image formed by the display 1 in the beam splitter 2 is located on the main optical axis of the concave reflecting mirror. In this way the virtual image presented by the display 1 is symmetrically distributed with respect to the main optical axis of the concave mirror, facilitating the symmetrical display of the image.
It is further preferred that a first line connecting the center of the display 1 with the center of the beam splitter 2, and a line connecting the center of the concave reflecting mirror with the center of the beam splitter 2 are second lines, the first line and the second line being symmetrical with respect to a perpendicular line along the surface of the beam splitter 2. In this way, the display 1 can be aligned with the center of the beam splitter 2, and the center of the beam splitter 2 is aligned with the center of the concave mirror, so that the widths of the beam splitter 2 and the concave mirror can be effectively utilized to meet the display size requirement.
By setting the light path in the far-image display device, the first image is imaged in the far-image display device to be upright, amplified and provided with a virtual image with a certain distance. Further, the distance of the virtual image from the human eye enables the user to clearly see the virtual image, so that the user can avoid that the distance is close, and the micro-stimulus image does not stimulate the eye to generate traction force for attempting to shorten the axis of the eye, and in addition, the distance is far, the focus of the virtual image is placed on the front side of the retina, and the influence of peripheral defocus on the eye is weaker than the influence generated by the focus falling on the front of the retina.
That is, the first image is displayed on the display 1, a part of the light emitted from the display 1 is emitted to the concave reflective mirror 3 through the beam splitter 2, and then an enlarged upright virtual image is formed by the concave reflective mirror 3, and the virtual image is the second image. A third predetermined area and a fourth predetermined area are arranged on the second image, the third predetermined area corresponds to the first predetermined area, and the fourth predetermined area corresponds to the second predetermined area.
The far-image display device further comprises a display screen, wherein in the far-image display device, the display screen is the spectroscope 2, and a user views an imaging result based on the first image through the display screen. When a user views the display screen, the imaging distance of the second image needs to be adjusted according to different eye conditions of different users, and the second image seen by different users needs to be a clear image. In addition, the distance between the second image and the display screen is a first image distance, and the first image distance can be adjusted but does not change after being determined. The second image can not affect eyes because the image seen by the user is clear, and the micro-stimulation effect on eyes is carried out only by superposing the images, so that the comfort level of watching is improved, the eyes are used for a long time, and the burden on the eyes is avoided, so that the using endurance is reduced. In addition, the method is also suitable for users with myopia, and the users with myopia can wear glasses for watching. The first image distance is unchanged after the determination, so that the viewing distance of the user is fixed, and the effect of continuous stimulation is achieved.
The superimposed image acquisition module is used for acquiring superimposed images based on the microstimulation images; the microstimulatory image and the overlay image comprise, viewing the overlay image using a viewing system having a first diopter, having substantially the same vision as viewing the microstimulatory image using a viewing system having a second diopter; wherein the second diopter is greater than the first diopter.
The viewing system having a first diopter includes: the observer's eyes together form an observation system having a first diopter, or the observer's eyes and the observer's fitted eyeglasses. The viewing system having a second diopter includes: the eyes of the observer and the device with a certain diopter arranged in front of the eyes are used as an observation system with a second diopter, or the eyes of the observer, glasses matched with the observer and the device with a certain diopter arranged in front of the glasses form an observation system with a second diopter.
Having substantially the same visual effect has several cases: the method of the present embodiment is targeted, and a series of measurements are made for the eye condition of an individual observer to obtain a suitable device with a certain diopter. The device enables an individual observer to observe the superimposed image using an observation system having a first diopter to have the same visual result as an observation system using a second diopter to observe the microstimulated image, i.e. the effect of the presentation of the images seen by the observer in both environments is substantially the same. Finally, a series of parameters which are targeted and personalized and suitable for individual watching and have good effects are obtained, and the length of an eye axis is shortened through peripheral defocus by adjusting the parameters, so that myopia is prevented or even treated.
The method involved in yet another scenario is generic and generalized and is not directed to an independent observer. Observers having the same or similar nature of eye condition are classified into a class according to the eye condition, and the vision level of a standard observer in this class will represent the eye condition of that class to obtain a device of a certain diopter suitable for use with a standard observer in this class according to the eye condition of the standard observer to be suitable for use with other observers in the class to which the standard observer belongs. The standard observers are representative of the average level of vision of such observers such that the diopters of the lenses to which the standard observers correspond are acceptable and acceptable to other observers of the same genus.
Further, the device with a certain diopter may be a lens, that is, the lens with a certain diopter is arranged in front of the eyes or the glasses, so that the observed micro-stimulus image has a certain ambiguity, and the micro-stimulus image with the ambiguity is further considered to fall on the front side of the retina by the brain, so that the eye can see clearly, and the force for shortening the axis of the eye is generated, so as to prevent myopia or relieve the degree of myopia.
Still further, the diopter of the lens is 0.5 D.ltoreq.x.ltoreq.1.5D.
The superimposed image has substantially the same visual effect as the image of the microstimulatory image through the x-lens. Preferably, x is 0.5D-1.5D. The superimposed image has a certain degree of ambiguity relative to the microstimulation image, the superimposed images with different degrees of ambiguity need to be stored, and as the eye conditions of different observers are different, the different conditions are matched with the images which penetrate through the diopter lens, and the images are taken out and displayed in a lookup table mode when the image processing device is used. In addition, during the matching process, observers with myopia can be matched based on the condition after wearing glasses.
In order to make the superimposed image and the image obtained by the micro-stimulus image with the diopter x through the lens have basically the same visual effect, a lens with a certain diopter can be placed in front of a camera or other equipment capable of shooting, after the micro-stimulus image is placed on the lens, the camera shoots the micro-stimulus image passing through the lens, and the obtained image is continuously detected and modified through a later test, so that a visual effect of an observer when observing the superimposed image can be achieved when the observer is looking at the image obtained by the lens with the diopter x. In addition, the adjustment of the blur degree may be directly performed on the microstimulated image to obtain a superimposed image, so long as the visual effect of the superimposed image viewed by an observer is ensured to be the same as that of an image obtained through a lens with refractive power x.
It should be noted that, referring to fig. 4 and fig. 5, when there is only one pattern in the microstimulation image, and there is more than one pattern in the superimposed image, referring to fig. 6, the patterns in the microstimulation image have the same visual effect after being observed through the lens, and the visual effect of one pattern in the superimposed image is the same. Since the superimposed image includes a plurality of images obtained by simply transforming the microstimulation image, the number of patterns in the superimposed image is not equal to the number of patterns in the microstimulation image, which will be described in advance.
A superimposed image is derived based on the microstimulated image, including but not limited to a first process, a second process, and a third process. The first process includes a microstimulation image with a certain degree of blur obtained after the microstimulation image is transmitted through a lens with a certain diopter. The second process performs simple conversion including conversion processes that do not affect the display content thereof, rotation, symmetry, and the like, on the basis of the first process. The third processing includes that a plurality of microstimulation images with the same ambiguity are annularly arranged, and further, the arrangement can be that the images obtained after the first processing are directly annularly arranged, or that slightly different images after the second processing are annularly arranged. That is, the images which are annularly arranged may be the same image or may be different images which are obtained by simply transforming one image.
According to different properties of the micro-stimulus image, the superimposed image can be obtained by the micro-stimulus image after the first treatment or after the first treatment, the second treatment and the third treatment.
In a specific implementation manner of this embodiment, the microstimulation image is an image in a ring shape as shown in fig. 4, and the microstimulation image is subjected to only a first process to obtain a superimposed image.
The microstimulated image includes a pattern formed according to a predetermined contrast of light and dark.
In yet another implementation of this embodiment, the microstimulation image is the image shown in fig. 5. And performing the first processing, the second processing and the third processing on the microstimulation image to obtain a superposition image. Further, the micro-stimulus image includes a white area having a symmetrical structure in a circular shape and a black area having a symmetrical structure except for the white area, for example, a black-and-white cross pattern in a circular shape, as shown in fig. 5. So arranged as to have a better microstimulation effect. Firstly, the microstimulated image with a certain blur obtained by the microstimulated image through a lens with diopter x is stored, and a plurality of third images with different blur are needed to be stored because x has a certain range. And then, obtaining a plurality of deformed images with the same ambiguity by rotating and/or symmetrically and the like in a transformation form, and arranging the deformed images. The arrangement mode comprises that a plurality of third images are arranged in a central symmetry mode; the plurality of images are arranged in a central symmetry and an axial symmetry mode, the distances between the adjacent third images are the same, and the distances between the third images and the positions of the central points are the same, namely the plurality of third images are annularly surrounded to form a superimposed image.
The presenting module is configured to present the superimposed image in a manner of covering the first predetermined area, and includes: a covering unit, configured to cover the superimposed image at a position corresponding to the first predetermined area of the first image; or a replacing unit for replacing the image content at the corresponding position within the first predetermined area of the first image with the superimposed image.
The first preset area corresponds to an area with an angle of view of 6-23 degrees, namely, a fovea which is imaged at 6-23 degrees. Preferably, the angle of view of the first predetermined area is 6 ° -15 °.
In one implementation of the present embodiment, the first image is presented on the display 1, a second image is obtained by the first optical system, and likewise, the superimposed image replaces the image content at a corresponding position within the first predetermined area of the first image, so that an enlarged, upright image of the superimposed image is displayed within the third predetermined area on the second image. The image with a certain ambiguity and a certain distance is presented in the peripheral defocusing area of the observer through the arrangement, the ambiguity stimulates the brain to generate a signal that the peripheral presented image is far away from the retina and the landing point is in front of the retina, meanwhile, the second superimposed image is far away through the action imaging of the light path, and the influence of the ambiguity on the brain is combined, so that the retina generates forward moving force to enable the peripheral image to be presented on the retina as much as possible to be clearly viewed, the effect of shortening the eye axis is further realized, and myopia can be prevented or even treated to a certain extent.
Further, the display 1 is subjected to a process of superimposing the first image and the superimposed image before displaying. For example, the superimposed image is first displayed instead of the image at the corresponding position of the first image, if the first image is a dynamic image, the dynamic image is further decoded into a still image frame by frame, then the superimposed image is used to replace the content corresponding to the first predetermined area in the still image, and the dynamic image which is presented by the first image and the superimposed image in a combined manner is output.
In yet another implementation of the present embodiment, the superimposed image is disposed between the magnified image and the observer to cover image content at a corresponding location within a third predetermined area of the magnified image. For example, the superimposed image may be disposed in the optical path as long as the third predetermined region of the enlarged image can be blocked without affecting the final presentation effect. Illustratively, the superimposed image is presented on an opaque carrier of paper or plastic or the like, for example the tele-graphic display device, which is arranged on the display screen of the tele-graphic display device to cover the third predefined area of the second image presented on the display screen. The peripheral defocus micro-stimulus amount is formed by the arrangement, the superimposed image has a certain degree of ambiguity, so that the brain generates signals with far image distance presented by the periphery, the retina is enabled to have forward approaching force to enable the peripheral image to be presented on the retina as much as possible so as to be clearly watched, the effect of shortening the eye axis is achieved, and myopia can be prevented or even treated to a certain extent.
In addition, in other implementations, by way of example, when a person views a video or other first image through a mobile phone, a television or a projection, and a paper printed with the superimposed image is covered in the first predetermined area of the first image to cover the content in the area, the effect of shortening the eye axis can be achieved to some extent, according to the situation of eyes of the person. Thus, methods similar to those mentioned above are also within the scope of the present disclosure.
The final rendered image through the above steps is shown with reference to fig. 8 and 9.
Example 3
The present embodiment provides an image rendering system, referring to fig. 3-9.
The image presentation system comprises a display device, a superposition device and a presentation device.
The display device acquires an area of the first image within a field angle at a first observation distance.
The first image comprises a static image and a dynamic image, and the dynamic image can obtain the static image frame by frame in a decoding mode.
The angle of view is the angle at which the head can see the limit of the range without rotating the eye while the head remains stationary. The range from the limit seen upward in the vertical direction to the limit seen downward is the vertical field angle, and the range from the limit seen leftward in the horizontal direction to the limit seen rightward is the horizontal field angle. The angles of view of different persons are different, the angles of view range from 0 degrees to 35 degrees, and the corresponding images are formed in the foveal imaging area. Further preferably, the angle of view is in the range of 0 ° -10 °.
The first observation distance is such that the first image at least partially exceeds the field of view angle and a range of field of view angles is determined. A first predetermined area is arranged on the periphery of the area in the angle of view, and the other areas except the first predetermined area on the first image are second predetermined areas.
In one implementation of this embodiment, the region of the first image within the field angle at the first observation distance may be determined and acquired by: the first image is acquired, the display content of the first image is not limited, the first image can be a video image or a static picture, the size of the first image is not excessively limited, and the length of the first image is only required to be longer than the distance from the leftmost side of the left eye to the rightmost side of the right eye, and the height of the first image is longer than the distance from the uppermost side of the eye to the bottommost side of the eye. And adjusting a first observation distance to enable at least part of the first image to be located at the periphery of the area in the view angle, setting a first preset area at the periphery of the area in the view angle, and enabling other areas except the first preset area on the first image to be second preset areas.
Further, the first image is an enlarged image via a first optical imaging device, the image having a first distance. The first optical imaging device includes: a display 1, a spectroscope 2 and a concave reflector 3; the optical path generated by the first optical imaging device comprises: the light emitted via the display 1 is transmitted via the beam splitter 2 to the concave mirror 3, and an enlarged image is formed by the concave mirror 3 to be transmitted into the eye of the observer.
In one implementation of this embodiment, the first optical imaging device is disposed within a tele-image display device. Referring to fig. 7, the display 1, the convex lens, the concave reflecting mirror, and the beam splitter 2 form an optical path. The display 1 is arranged as a light source between the beam splitter 2 and the concave reflecting mirror, and is preferably integrally lower than the lower surfaces of the beam splitter 2 and the concave reflecting mirror so as not to affect the optical path between the beam splitter 2 and the concave reflecting mirror.
The display 1 is arranged below the convex lens. The convex lens has an outer surface that is convex. One of the outer surfaces of the convex lens opposite to or far from the display 1 is convex, in the specific embodiment, a bottom surface, and the other is a plane; the convex outer surface, when aligned with the concave mirror along a predetermined direction, coincides entirely with the contour of the reflective surface. In this arrangement, the distortion of the image caused by the precision of design and processing of the concave mirror can be counteracted, since the human eye is very sensitive to the observation of the video, the slight distortion very affects the observation, and the distortion caused by the convex lens and the concave mirror can be counteracted with each other in practice by the complementary arrangement of the convex lens and the concave mirror, thereby avoiding the distortion of the image.
Further, the center point of the display 1 is disposed on the main optical axis of the convex lens and within the focal length of the convex lens, thereby forming a second virtual image a of the display 1 that is enlarged upright on the side of the convex lens close to the display 1.
The beam splitter 2 is an optical device of the prior art and is designed primarily by the surface in contact with the light so that a portion of the light directed towards said surface is transmitted and another portion is reflected. The proportion of incident light rays and reflected light rays at different angles can be adjusted by adjusting the light rays with different proportions to achieve reflection and light ray transmission with different proportions through setting the microstructure of the surface. This is a common optical component in the prior art and thus its microstructure is not developed in detail in this embodiment.
When the light emitted from the display 1 irradiates the inner surface of the beam splitter 2, the beam splitter 2 reflects a part of the light of the display 1, and the other part of the light is transmitted through the beam splitter 2. The reflected light is in this embodiment directed towards a concave mirror behind the beam splitter 2, whereas the transmitted light is emitted upwards from said beam splitter 2.
In addition, a part of light emitted from the display 1 passes through the beam splitter 2 and reaches the beam splitter 2 for the first time, and then is transmitted out from the beam splitter 2 under the beam splitting action of the beam splitter 2, so that a part of brightness is weakened, and a part of light after the reflecting action of the concave reflector is reflected to the inner space and is not transmitted out when passing through the beam splitter 2 for the second time, so that the brightness of the light injected into eyes of an observer is further reduced, and the effect of protecting vision is played.
In this case, the virtual image a 'of the display 1 formed in the beam splitter 2 needs to be less than the focal length of the concave mirror, i.e. within the focal point F of the concave mirror, from the concave mirror, so that when the virtual image a' is re-imaged a in the concave mirror, an enlarged, upright virtual image is ensured for viewing by the viewer.
Preferably, in order to prevent distortion of the image of the display 1, on the one hand, the processing precision of the respective optical devices needs to be high, more importantly, the virtual image a' formed by the display 1 in the beam splitter 2 is parallel to the focal plane of the concave reflecting mirror as a whole, and even more preferably, the center of the virtual image formed by the display 1 in the beam splitter 2 is located on the main optical axis of the concave reflecting mirror. In this way the virtual image presented by the display 1 is symmetrically distributed with respect to the main optical axis of the concave mirror, facilitating the symmetrical display of the image.
It is further preferred that a first line connecting the center of the display 1 with the center of the beam splitter 2, and a line connecting the center of the concave reflecting mirror with the center of the beam splitter 2 are second lines, the first line and the second line being symmetrical with respect to a perpendicular line along the surface of the beam splitter 2. In this way, the display 1 can be aligned with the center of the beam splitter 2, and the center of the beam splitter 2 is aligned with the center of the concave mirror, so that the widths of the beam splitter 2 and the concave mirror can be effectively utilized to meet the display size requirement.
By setting the light path in the far-image display device, the first image is imaged in the far-image display device to be upright, amplified and provided with a virtual image with a certain distance. Further, the distance of the virtual image from the human eye enables the user to clearly see the virtual image, so that the user can avoid that the distance is close, and the micro-stimulus image does not stimulate the eye to generate traction force for attempting to shorten the axis of the eye, and in addition, the distance is far, the focus of the virtual image is placed on the front side of the retina, and the influence of peripheral defocus on the eye is weaker than the influence generated by the focus falling on the front of the retina.
That is, the first image is displayed on the display 1, a part of the light emitted from the display 1 is emitted to the concave reflective mirror 3 through the beam splitter 2, and then an enlarged upright virtual image is formed by the concave reflective mirror 3, and the virtual image is the second image. A third predetermined area and a fourth predetermined area are arranged on the second image, the third predetermined area corresponds to the first predetermined area, and the fourth predetermined area corresponds to the second predetermined area.
The far-image display device further comprises a display screen, wherein in the far-image display device, the display screen is the spectroscope 2, and a user views an imaging result based on the first image through the display screen. When a user views the display screen, the imaging distance of the second image needs to be adjusted according to different eye conditions of different users, and the second image seen by different users needs to be a clear image. In addition, the distance between the second image and the display screen is a first image distance, and the first image distance can be adjusted but does not change after being determined. The second image can not affect eyes because the image seen by the user is clear, and the micro-stimulation effect on eyes is carried out only by superposing the images, so that the comfort level of watching is improved, the eyes are used for a long time, and the burden on the eyes is avoided, so that the using endurance is reduced. In addition, the method is also suitable for users with myopia, and the users with myopia can wear glasses for watching. The first image distance is unchanged after the determination, so that the viewing distance of the user is fixed, and the effect of continuous stimulation is achieved.
A superimposing device for obtaining a superimposed image based on the microstimulation image; the microstimulatory image and the overlay image comprise, viewing the overlay image using a viewing system having a first diopter, having substantially the same vision as viewing the microstimulatory image using a viewing system having a second diopter; wherein the second diopter is greater than the first diopter.
The viewing system having a first diopter includes: the observer's eyes together form an observation system having a first diopter, or the observer's eyes and the observer's fitted eyeglasses. The viewing system having a second diopter includes: the eyes of the observer and the device with a certain diopter arranged in front of the eyes are used as an observation system with a second diopter, or the eyes of the observer, glasses matched with the observer and the device with a certain diopter arranged in front of the glasses form an observation system with a second diopter.
Having substantially the same visual effect has several cases: the method of the present embodiment is targeted, and a series of measurements are made for the eye condition of an individual observer to obtain a suitable device with a certain diopter. The device enables an individual observer to observe the superimposed image using an observation system having a first diopter to have the same visual result as an observation system using a second diopter to observe the microstimulated image, i.e. the effect of the presentation of the images seen by the observer in both environments is substantially the same. Finally, a series of parameters which are targeted and personalized and suitable for individual watching and have good effects are obtained, and the length of an eye axis is shortened through peripheral defocus by adjusting the parameters, so that myopia is prevented or even treated.
The method involved in yet another scenario is generic and generalized and is not directed to an independent observer. Observers having the same or similar nature of eye condition are classified into a class according to the eye condition, and the vision level of a standard observer in this class will represent the eye condition of that class to obtain a device of a certain diopter suitable for use with a standard observer in this class according to the eye condition of the standard observer to be suitable for use with other observers in the class to which the standard observer belongs. The standard observers are representative of the average level of vision of such observers such that the diopters of the lenses to which the standard observers correspond are acceptable and acceptable to other observers of the same genus.
Further, the device with a certain diopter may be a lens, that is, the lens with a certain diopter is arranged in front of the eyes or the glasses, so that the observed micro-stimulus image has a certain ambiguity, and the micro-stimulus image with the ambiguity is further considered to fall on the front side of the retina by the brain, so that the eye can see clearly, and the force for shortening the axis of the eye is generated, so as to prevent myopia or relieve the degree of myopia.
Still further, the diopter of the lens is 0.5 D.ltoreq.x.ltoreq.1.5D.
The superimposed image has substantially the same visual effect as the image of the microstimulatory image through the x-lens. Preferably, x is 0.5D-1.5D. The superimposed image has a certain degree of ambiguity relative to the microstimulation image, the superimposed images with different degrees of ambiguity need to be stored, and as the eye conditions of different observers are different, the different conditions are matched with the images which penetrate through the diopter lens, and the images are taken out and displayed in a lookup table mode when the image processing device is used. In addition, during the matching process, observers with myopia can be matched based on the condition after wearing glasses.
In order to make the superimposed image and the image obtained by the micro-stimulus image with the diopter x through the lens have basically the same visual effect, a lens with a certain diopter can be placed in front of a camera or other equipment capable of shooting, after the micro-stimulus image is placed on the lens, the camera shoots the micro-stimulus image passing through the lens, and the obtained image is continuously detected and modified through a later test, so that a visual effect of an observer when observing the superimposed image can be achieved when the observer is looking at the image obtained by the lens with the diopter x. In addition, the adjustment of the blur degree may be directly performed on the microstimulated image to obtain a superimposed image, so long as the visual effect of the superimposed image viewed by an observer is ensured to be the same as that of an image obtained through a lens with refractive power x.
It should be noted that, referring to fig. 4 and fig. 5, when there is only one pattern in the microstimulation image, and there is more than one pattern in the superimposed image, referring to fig. 6, the patterns in the microstimulation image have the same visual effect after being observed through the lens, and the visual effect of one pattern in the superimposed image is the same. Since the superimposed image includes a plurality of images obtained by simply transforming the microstimulation image, the number of patterns in the superimposed image is not equal to the number of patterns in the microstimulation image, which will be described in advance.
A superimposed image is derived based on the microstimulated image, including but not limited to a first process, a second process, and a third process. The first process includes a microstimulation image with a certain degree of blur obtained after the microstimulation image is transmitted through a lens with a certain diopter. The second process performs simple conversion including conversion processes that do not affect the display content thereof, rotation, symmetry, and the like, on the basis of the first process. The third processing includes that a plurality of microstimulation images with the same ambiguity are annularly arranged, and further, the arrangement can be that the images obtained after the first processing are directly annularly arranged, or that slightly different images after the second processing are annularly arranged. That is, the images which are annularly arranged may be the same image or may be different images which are obtained by simply transforming one image.
According to different properties of the micro-stimulus image, the superimposed image can be obtained by the micro-stimulus image after the first treatment or after the first treatment, the second treatment and the third treatment.
In a specific implementation manner of this embodiment, the microstimulation image is an image in a ring shape as shown in fig. 4, and the microstimulation image is subjected to only a first process to obtain a superimposed image.
The microstimulated image includes a pattern formed according to a predetermined contrast of light and dark.
In yet another implementation of this embodiment, the microstimulation image is the image shown in fig. 5. And performing the first processing, the second processing and the third processing on the microstimulation image to obtain a superposition image. Further, the micro-stimulus image includes a white area having a symmetrical structure in a circular shape and a black area having a symmetrical structure except for the white area, for example, a black-and-white cross pattern in a circular shape, as shown in fig. 5. So arranged as to have a better microstimulation effect. Firstly, the microstimulated image with a certain blur obtained by the microstimulated image through a lens with diopter x is stored, and a plurality of third images with different blur are needed to be stored because x has a certain range. And then, obtaining a plurality of deformed images with the same ambiguity by rotating and/or symmetrically and the like in a transformation form, and arranging the deformed images. The arrangement mode comprises that a plurality of third images are arranged in a central symmetry mode; the plurality of images are arranged in a central symmetry and an axial symmetry mode, the distances between the adjacent third images are the same, and the distances between the third images and the positions of the central points are the same, namely the plurality of third images are annularly surrounded to form a superimposed image.
The presenting device presents the superimposed image in a manner of covering the first predetermined area, including: an overlay presentation means for overlaying the superimposed image at a position corresponding to the first predetermined area of the first image; or alternative rendering means for replacing image content at a corresponding location within the first predetermined area of the first image with the superimposed image.
The first preset area corresponds to an area with an angle of view of 6-23 degrees, namely, a fovea which is imaged at 6-23 degrees. Preferably, the angle of view of the first predetermined area is 6 ° -15 °.
In one implementation of the present embodiment, the first image is presented on the display 1, a second image is obtained by the first optical system, and likewise, the superimposed image replaces the image content at a corresponding position within the first predetermined area of the first image, so that an enlarged, upright image of the superimposed image is displayed within the third predetermined area on the second image. The image with a certain ambiguity and a certain distance is presented in the peripheral defocusing area of the observer through the arrangement, the ambiguity stimulates the brain to generate a signal that the peripheral presented image is far away from the retina and the landing point is in front of the retina, meanwhile, the second superimposed image is far away through the action imaging of the light path, and the influence of the ambiguity on the brain is combined, so that the retina generates forward moving force to enable the peripheral image to be presented on the retina as much as possible to be clearly viewed, the effect of shortening the eye axis is further realized, and myopia can be prevented or even treated to a certain extent.
Further, the display 1 is subjected to a process of superimposing the first image and the superimposed image before displaying. For example, the superimposed image is first displayed instead of the image at the corresponding position of the first image, if the first image is a dynamic image, the dynamic image is further decoded into a still image frame by frame, then the superimposed image is used to replace the content corresponding to the first predetermined area in the still image, and the dynamic image which is presented by the first image and the superimposed image in a combined manner is output.
In yet another implementation of the present embodiment, the superimposed image is disposed between the magnified image and the observer to cover image content at a corresponding location within a third predetermined area of the magnified image. For example, the superimposed image may be disposed in the optical path as long as the third predetermined region of the enlarged image can be blocked without affecting the final presentation effect. Illustratively, the superimposed image is presented on an opaque carrier of paper or plastic or the like, for example the tele-graphic display device, which is arranged on the display screen of the tele-graphic display device to cover the third predefined area of the second image presented on the display screen. The peripheral defocus micro-stimulus amount is formed by the arrangement, the superimposed image has a certain degree of ambiguity, so that the brain generates signals with far image distance presented by the periphery, the retina is enabled to have forward approaching force to enable the peripheral image to be presented on the retina as much as possible so as to be clearly watched, the effect of shortening the eye axis is achieved, and myopia can be prevented or even treated to a certain extent.
In addition, in other implementations, by way of example, when a person views a video or other first image through a mobile phone, a television or a projection, and a paper printed with the superimposed image is covered in the first predetermined area of the first image to cover the content in the area, the effect of shortening the eye axis can be achieved to some extent, according to the situation of eyes of the person. Thus, methods similar to those mentioned above are also within the scope of the present disclosure.
The final rendered image through the above steps is shown with reference to fig. 8 and 9.
