Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image processing, and in particular to a device for applying blur stimulation to a user's monocular or binocular vision. BACKGROUND

[0002] Genetic studies have shown that environmental factors that produce abnormal contrast between adjacent cone cells are a signal for axial elongation and myopia development. There are two types of photoreceptor cells in the retina (i.e., cone cells and rod cells), cone cells are responsible for perceiving color, object details, and image changes, cone cells include L-type cone cells, M-type cone cells, and S-type cone cells, and each perceives a long-wave, middle-wave, and short-wave portion of the visible light range. The L:M ratio is considered an indicator of myopia susceptibility, but the L:M ratio varies by race and individual, and the L:M ratio is high, the incidence of myopia is low, and the L:M ratio is low (even close to 1:1), the incidence of myopia is high. Due to the change in the structure of the opsin in the L-type cone cell, the L:M ratio is reduced, which manifests as a false contrast signal (i.e., a higher contrast signal), and the false contrast signal is considered a factor that leads to axial growth.

[0003] A double-blind randomized controlled clinical trial by Rappon et al. found that reducing retinal contrast can effectively slow down the progression of myopia, with a 74% reduction in myopia diopter progression and a 50% reduction in axial growth. The brain is selective of retinal signals, and the regulation of axial growth is dominated by peripheral retinal visual experience, and the reduction of contrast in the periphery compared to the center can more significantly affect the change in the axial length, and the low contrast in the foveal region greatly affects the visual quality, which can easily cause visual fatigue and accelerate the development of myopia. In the prior art, a frame functional glasses is designed, the small area of the lens center directly opposite the pupil is fully transparent, and the periphery is uniformly distributed with micro diffusers. After the light passes through the diffusers, the light is dispersed in front of and behind the lens, thereby reducing the signal difference between adjacent cone cells. However, the existing frame functional glasses are implemented by micro diffusers distributed on the lens, and the user receives a fixed static blur stimulation, and long-term use of the eyes will cause adaptation, and the effect of myopia prevention and control will be weakened. In addition, the frame functional glasses have a clear view only in the area directly opposite the pupil, and when the eyeball rotates, the view through the peripheral diffuser area will become blurred and unclear, affecting the visual quality, so the user will use the head compensation method to look around by turning the head but not moving the eyeball, which will affect the saccadic eye movement ability over a long period of time. At the same time, the user's myopia degree changes, and the matching frame functional glasses need to be replaced from time to time, which increases the economic burden of the price and maintenance of the frame functional glasses.

[0004] Therefore, it is necessary to improve the contrast adjustment method in the prior art to solve the above problems. SUMMARY

[0005] The present application aims to solve the problem that the existing method of reducing the retinal contrast has the limitations of algorithm design, the fixed static blur stimulus received by the user, the adaptation of the long-time use of the eyes, the weakening of the myopia prevention effect, the clear vision only in the area directly opposite the pupil of the glasses, the blurred vision if the eyeball rotates, the problem of the influence on the saccadic eye movement ability of the eyeball if the user rotates by the head compensation, the change of the myopia degree of the user, the need for the periodic replacement of the matching glasses, and the economic burden.

[0006] To achieve the above-mentioned purpose, the present application provides a method for applying blur stimulus to the user's monocular or binocular vision, comprising:

[0007] obtaining the fixation point corresponding to the user's monocular or binocular vision to determine the fixation area corresponding to the user's monocular or binocular vision, and determining the central area and the peripheral area in the fixation area;

[0008] forming a training image set in the fixation area, wherein the central area is clear and at least part of the peripheral area is blurred, to apply blur stimulus to the user's monocular or binocular vision by at least one training image in the training image set;

[0009] wherein the central area corresponds to the central field of view determined by the fixation point of the user's monocular or binocular vision, the peripheral area corresponds to the peripheral field of view determined by the fixation point of the user's monocular or binocular vision, and the training image set contains at least one training image.

[0010] As a further improvement of the present application, the boundary between the clear area and the blurred area in the single training image is clear, or the boundary between the clear area and the blurred area is blurred.

[0011] As a further improvement of the present application, the blur of at least part of the peripheral area is achieved by arranging a plurality of speckles in at least part of the area, the area between the speckles is clear, and the edge of the speckle is not blurred, or the edge of the speckle is blurred.

[0012] As a further improvement of the present application, the training image set contains at least two training images with different blurred areas, so that the blurred area and the clear area in the peripheral area dynamically change within the peripheral area when the training image set applies blur stimulus to the user's monocular or binocular vision.

[0013] As a further improvement of the present invention, the blurred area and the clear area in the surrounding area dynamically change within the surrounding area, including: the blurred area in the surrounding area switches between clear and blurred, and the switching frequency is 0-20Hz.

[0014] As a further improvement of the present invention, if a local area in the surrounding area is blurred, the blurred area and the clear area in the surrounding area dynamically change within the surrounding area, including: the clear area in the surrounding area moves within the blurred area.

[0015] As a further improvement of the present invention, if a local area in the peripheral region is blurred, and the blurred area and the clear area in the peripheral region are arranged in a ring-shaped sequence from the gaze point outward in a radial direction;

[0016] The blurred and sharp areas in the surrounding area dynamically change within the surrounding area, including:

[0017] The radial widths of the clear and blurred regions in the surrounding area gradually increase or decrease, or the clear and blurred regions in the surrounding area diffuse radially from the inside out.

[0018] Based on the same inventive concept, this invention also discloses a device for applying blurred stimulation to a user's monocular or binocular vision, comprising:

[0019] An adjustment mechanism is used to obtain the fixation point corresponding to the user's monocular or binocular vision, to determine the fixation area corresponding to the user's monocular or binocular vision, and to determine the central area and the peripheral area in the fixation area. A training image set is formed in the fixation area with the central area being clear and at least some areas in the peripheral area being blurred, so that at least one training image in the training image set can be used to apply a blurred stimulus to the user's monocular or binocular vision.

[0020] The central region corresponds to the central field of view determined by the user's monocular or binocular gaze point, and the peripheral region corresponds to the peripheral field of view determined by the user's monocular or binocular gaze point. The training image set contains at least one training image.

[0021] As a further improvement of the present invention, the adjustment mechanism includes:

[0022] A first screen is disposed at the gaze region and configured to display a set of training images in the gaze region that are clear in the central area and blurred in at least a portion of the surrounding areas.

[0023] As a further improvement of the present invention, the adjustment mechanism includes:

[0024] An adjustment element is disposed between the gaze region and the user's monocular or binocular vision, and is configured to adjust the sharpness of an initial image set displayed in the gaze region so as to form a training image set with a clear central region and at least some of the surrounding regions blurred from the adjusted initial image set.

[0025] The initial image includes at least one initial image.

[0026] As a further improvement of the present invention, the adjustment mechanism further includes:

[0027] A second screen is disposed at the gaze area and configured to display the initial image set in the gaze area.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] Based on the user's fixation point corresponding to their monocular or binocular vision, a fixation area is determined, along with a central region corresponding to the central field of view of the fixation point and a peripheral region corresponding to the peripheral field of view of the fixation point. A training image set is then formed within the fixation area, where the central region is clear and at least some of the peripheral regions are blurred. This ensures that the central region corresponding to the user's monocular or binocular central field of view in the training images in the training image set is always clear and the peripheral regions corresponding to the user's monocular or binocular peripheral field of view are at least partially blurred. While ensuring the user's monocular or binocular visual quality, the contrast of the peripheral regions is further reduced, thereby reducing the difference in contrast signals received by two adjacent cone cells on the retina. This ultimately aims to inhibit axial elongation. At the same time, it also solves the problem that in existing technologies, only the area directly facing the pupil is clear when the glasses are on; if the eyeball moves, it becomes blurry. If the user uses head compensation to move the eyeball, it will affect the eyeball's ability to perform saccades, tracking, and other eye movements. Attached Figure Description

[0041] The present invention will be described in detail below in conjunction with the various implementation manners shown in the accompanying drawings. However, it should be noted that these implementation manners are not limitations on the present invention. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these implementation manners falls within the protection scope of the present invention.

[0042] Please refer Figures 1 to 11 As shown, the present invention discloses a specific implementation manner of a method (hereinafter referred to as "the method") and a device (hereinafter referred to as "the device") for applying a blur stimulus to a user's monocular or binocular vision. The method can run on the device, which can be, for example, a wearable smart glasses, a VR glasses, a computer, etc. The method is used to form a training image set with a clear central region and at least partially blurred peripheral region in the fixation area corresponding to the user's monocular or binocular vision, so as to apply a blur stimulus to the user's monocular or binocular vision by at least one training image in the training image set, thereby reducing the signal difference between adjacent cone cells corresponding to the user's monocular or binocular vision, that is, reducing the contrast, and thus reducing the influence of the growth of the eye axis caused by the transmission of incorrect contrast signals.

[0043] Refer Figure 1 As shown, the method specifically includes the following steps S1 to S2.

[0044] Step S1: Obtain the fixation point corresponding to the user's monocular or binocular vision to determine the fixation area corresponding to the user's monocular or binocular vision, and determine the central region and the peripheral region in the fixation area.

[0045] Specifically, if a blurred stimulus is applied to a user's single eye, eye-tracking technology is used to capture the pupil position corresponding to that single eye to obtain the user's fixation point. Based on this fixation point, the user's fixation area for that single eye is determined, including the central region within the fixation area corresponding to the central field of vision and the peripheral region within the fixation area corresponding to the peripheral field of vision. Similarly, if a blurred stimulus is applied to the user's two eyes, eye-tracking technology is used to capture the pupil position and interpupillary distance information corresponding to the user's two eyes to obtain the user's fixation point. Based on this fixation point, the user's fixation area for that two eyes is determined, including the central region within the fixation area corresponding to the central field of vision and the peripheral region within the fixation area corresponding to the peripheral field of vision.

[0046] For example, refer Figure 2 As shown, Figure 2 The diagram shows a view of the gaze region 10, where point 13 is the gaze point corresponding to the user's monocular or binocular vision (i.e., gaze point 13), region 11 is the central region of the gaze region 10 determined based on gaze point 13 (i.e., central region 11), and region 12 is the peripheral region of the gaze region 10 determined based on gaze point 13 (i.e., peripheral region 12). If the eyeball moves, the user's monocular or binocular gaze point is captured again using eye-tracking technology. That is, gaze point 13 is redefined based on the user's monocular or binocular vision, and the central and peripheral regions of the gaze region are redefined based on the redefined gaze point. Based on this, a training image is subsequently formed in the fixation area where the central region is clear and at least some of the peripheral regions are blurred. This ensures that the central region of the user's monocular or binocular central field of view in the training image is clear and at least some of the peripheral regions of the user's monocular or binocular peripheral field of view are blurred. This solves the problem in the prior art where the glasses only provide clear vision in the area directly in front of the pupil, and the vision becomes blurry when the eyeball moves. Furthermore, if the user uses head compensation to move the eyeball, it will affect the eyeball's ability to perform saccades, follow movements, and other eye movements.

[0047] It should be noted that the aforementioned eye-tracking technology can be any existing technology, as long as it can capture the pupil position of the user's single eye and the pupil position and interpupillary distance information of the user's two eyes. This embodiment does not impose any specific limitations on this. Furthermore, in this application, the central region corresponds to the central field of view determined by the user's monocular or binocular fixation point, and the peripheral region corresponds to the peripheral field of view determined by the user's monocular or binocular fixation point. Alternatively, the peripheral region can be considered as the area outside the central region within the fixation area. The field of view angle of the central field of view is no greater than 25 degrees, and preferably 25 degrees, while the field of view angle of the fixation area is greater than or equal to 80 degrees.

[0048] Step S2: Form a training image set in the fixation area with a clear central region and at least some blurred peripheral regions, so as to apply a blurred stimulus to the user's monocular or binocular vision using at least one training image from the training image set.

[0049] Specifically, a training image set is formed within the fixation area, where the central region is clear and at least some areas of the surrounding region are blurred. The training image set contains at least one training image; that is, it can contain only one training image or multiple training images. A single training image may have a clear central region and blurred surrounding regions, or a clear central region and partially blurred surrounding regions. This allows for the application of blurred stimulation to the user's monocular or binocular sense using one or more training images from the training image set. In short, if the training image set contains only one training image, in one implementation, the training image has a clear central region and blurred surrounding regions; in another implementation, the training image has a clear central region and partially blurred surrounding regions, thereby achieving static application of blurred stimulation to the user's monocular or binocular sense based on a single training image. If the training image set contains multiple training images, each of which is either clear in the central area and blurred in the peripheral area, or clear in the central area and partially blurred in the peripheral area, then based on these multiple training images, dynamic blurring stimulation can be applied to the user's monocular or binocular vision. This dynamic training image set enhances the blurring stimulation applied to the user's monocular or binocular vision, thereby solving the problem that existing methods of reducing retinal contrast suffer from limitations in their algorithm design. These methods result in users receiving fixed, static blurring stimulation, which, with prolonged use, leads to eye adaptation and weakens the myopia control effect.

[0050] It should be noted that in this application, the training images always ensure that the central region of the user's monocular or binocular central field of view is clear and at least part of the peripheral region of the user's monocular or binocular peripheral field of view is blurred. This ensures the visual quality of the user's monocular or binocular vision while further reducing the contrast of the peripheral region, thereby reducing the difference in contrast signals received by two adjacent cone cells on the retina, and ultimately achieving the purpose of inhibiting axial elongation.

[0051] In one implementation, in a single training image, the boundary between the clear and blurred regions is distinct, or the boundary between the clear and blurred regions is blurred, specifically, the boundary between the clear and blurred regions may have feathered blurring. More specifically, blurring of at least a portion of the surrounding region is achieved by arranging a plurality of noise points in at least a portion of the region, where the areas between the noise points are clear and the edges of the noise points are not blurred, or the edges of the noise points are blurred, specifically, the edges of the noise points may have feathered blurring. For example, refer toFigure 3 and Figure 4 As shown, Figure 3 The training image shown has clear regions between noise points, and the edges of the noise points are not blurred. Figure 4 The training image shown has clear regions between noise points, and the edges of the noise points are feathered and blurred to create an uneven semi-transparent effect. Preferably, the training image has clear regions between noise points, and the edges of the noise points are feathered and blurred, specifically with Gaussian feathering.

[0052] It should be noted that the above example of blurring at least a portion of the surrounding area by arranging several noise points is illustrative. In this application, blurring of at least a portion of the surrounding area can also be achieved through other methods, and this embodiment does not specifically limit this. Simultaneously, the clarity of the blurred area in the training image can be adjusted by adjusting the transparency of the noise points. Optionally, the transparency of the noise points can be adjusted between 0 and 100, and the color can be adjusted between R(0)G(0)B(0) and R(0)G(0)B(255) to facilitate adjustment of the clarity of the training image, thereby solving the problem of users needing to periodically replace matching glasses due to changes in their myopia, which creates an economic burden.

[0053] The training image set contains at least two training images with different blur regions. When a blur stimulus is applied to a user's monocular or binocular vision using the training image set, the blur region and the sharp region in the peripheral region dynamically change within the peripheral region. This dynamic training image enhances the blur stimulus applied to the user's monocular or binocular vision, thereby preventing the user's monocular or binocular vision from adapting to the blur stimulus applied by the training image.

[0054] More specifically, in one implementation, the blurred and sharp regions within the surrounding area dynamically change, including switching between sharp and blurred states within the blurred region. (See reference...) Figure 5 and Figure 6 As shown, assume the training image set contains two training images. Figure 5 The training images shown are those where both the central and peripheral regions are clear. Figure 6The training images shown are those with a clear central area and a blurred peripheral area. When a blurred stimulus is applied to a user's monocular or binocular vision, the fixation area sequentially forms two training images and cycles through them. This allows the blurred peripheral area to switch between clear and blurred states at a frequency of 0-20Hz (e.g., 0Hz, 4Hz, 8Hz, 10Hz, 12Hz, 15Hz, 18Hz, or 20Hz). In other words, the blurred peripheral area flickers between clear and blurred states to further enhance the blurred stimulus applied to the user's monocular or binocular vision by the training image set. Preferably, the flickering frequency range is between 0-20Hz (e.g., 0Hz, 4Hz, 8Hz, 10Hz, 12Hz, 15Hz, 18Hz, or 20Hz), and preferably 10Hz.

[0055] In one implementation, if a local area in the surrounding region is blurred, the blurred area and the clear area in the surrounding region dynamically change within the surrounding region, including: the clear area in the surrounding region moving within the blurred area. (See reference...) Figure 7 As shown, assume the training image set contains two images. Both training images have a clear central region, a clear circular region in the peripheral region, and blurred regions other than the circular region in the peripheral region. Furthermore, the positions of the circular regions in the peripheral regions of the two training images are different. Figure 7 The example shown uses only one training image. Based on this, when applying blurred stimulation to a user's monocular or binocular vision, the fixation area sequentially forms two training images and cycles through them, thereby enabling the clear area in the peripheral region to move within the blurred area, further enhancing the blurred stimulation applied to the user's monocular or binocular vision by the training image set.

[0056] In one implementation, if a local area in the surrounding region is blurred, and the blurred and clear areas in the surrounding region are arranged in a ring-like pattern with intervals from the point of gaze outwards (e.g., Figure 8 The training images shown are Figure 9 (The training image shown). The blurred and sharp regions in the peripheral region dynamically change within the peripheral region, including: the radial width of the sharp and blurred regions in the peripheral region gradually increases or decreases; or, the sharp and blurred regions in the peripheral region diffuse radially from the inside out, thereby further enhancing the blurred stimulation exerted on the user's monocular or binocular vision by the training image set.

[0057] It should be noted that the above description of dynamically applying blurred stimulation to the user's monocular or binocular vision using two training images in the training image set is merely a specific embodiment. The training images in the training image set can also be presented in any other way, as long as they can form training images with a clear central region and at least some blurred regions in the surrounding region. This embodiment does not specifically limit the clear and blurred regions in the surrounding region of the training image.

[0058] Based on the same inventive concept, this application discloses an apparatus applied to this method. The apparatus includes: an adjustment mechanism that acquires the user's fixation point corresponding to their monocular or binocular vision to determine a central region and a peripheral region within the user's fixation area corresponding to their monocular or binocular vision. A training image set is formed within the fixation area, where the central region is clear and at least a portion of the peripheral region is blurred. A blurred stimulus is applied to the user's monocular or binocular vision using at least one training image from the training image set. The central region corresponds to the central field of view determined by the user's monocular or binocular fixation point, and the peripheral region corresponds to the peripheral field of view determined by the user's monocular or binocular fixation point. The training image set contains at least one training image.

[0059] In one implementation, the reference Figure 10 As shown, the adjustment structure includes: a first screen 21, which is located at the fixation area (not labeled) corresponding to the user's binoculars or monoculars (i.e., eyeballs 22), and is configured to display a set of training images in the fixation area where the central area is clear and at least some of the surrounding areas are blurred. The user fixates on the training image displayed on the first screen 21, where the central area is clear and at least some of the surrounding areas are blurred, thereby applying a blurred stimulus to the user's monoculars or binoculars using at least one training image from the training image set. In short, the first screen 21 is the screen that displays the training image set, and can be, for example, a computer, tablet, mobile phone, or other component capable of displaying training images. When applying blurred stimulation to the user's monoculars or binoculars (i.e., eyeballs 22), the first screen 21 may display only one training image, or it may display multiple training images in rotation. Meanwhile, the first screen 21 is equipped with detection logic and control logic. The detection logic can detect the user's gaze point corresponding to monocular or binocular vision, thereby ensuring that the central area of ​​the user's monocular or binocular central field of view in the training image is clear and the peripheral area of ​​the user's monocular or binocular peripheral field of view is at least partially blurred. The control logic can be used to adjust the clarity of the training image, thereby allowing the training image to be adjusted according to the user's needs.

[0060] In one implementation, the reference Figure 11As shown, the adjustment mechanism includes an adjustment component 32, which is disposed between the gaze area (not labeled) and the user's monocular or binocular (i.e., eyeball 31) and configured to adjust the sharpness of the initial image set displayed in the gaze area, so as to form a training image set with a clear central area and at least some blurry areas in the peripheral area from the adjusted initial image set; wherein, the initial image set contains at least one initial image. In this application, the initial image refers to an image with both the central and peripheral areas being clear, and the training image refers to an image with a clear central area and some blurry areas in the peripheral area. In short, the adjustment component 32 is the component that adjusts the sharpness of the initial image. The user's binocular or monocular (i.e., eyeball 31) forms a training image with a clear central area and at least some blurry areas in the peripheral area through the adjustment component 32, and can be, for example, a patch, AR glasses, naked-eye 3D, or a virtual layer that adjusts the sharpness of the initial image through digital zoom, etc. Meanwhile, the adjustment component 32 is equipped with detection logic and control logic. The detection logic can detect the user's gaze point corresponding to monocular or binocular vision, thereby ensuring that the central area of ​​the user's monocular or binocular central field of view in the training image is clear and the peripheral area of ​​the user's monocular or binocular peripheral field of view is at least partially blurred. The control logic can adjust the clarity of the training image formed by the user's monocular or binocular vision through the adjustment component 32, thereby allowing the training image to be adjusted according to the user's needs.

[0061] In one implementation, the reference Figure 11 As shown, the adjustment mechanism also includes a second screen 33. That is, the adjustment mechanism includes an adjustment member 32 and a second screen 33. The second screen 33 is located in the gaze area (not labeled) and configured to display an initial image set in the gaze area. In short, the adjustment member 32 is positioned between the user's monocular or binocular vision (i.e., eyeball 31) and the second screen 33. The user's monocular or binocular vision gazes through the adjustment member 32 at the initial image displayed on the second screen to form a training image with a clear central area and at least some areas of the peripheral area blurred. This could be, for example, VR glasses.
