Description

Technical Field

[0001] This application relates to the field of display technologies, and particularly to a preset image type artificial eye lens display device. Background Art

[0002] At present, some people have atrophied or removed eyeballs due to severe eye trauma or diseases, or have underdeveloped or non-developed eyeballs due to congenital anophthalmia or microphthalmia. To protect the eye socket and improve appearance, some of these patients can directly place an artificial eye lens in the conjunctival sac, and most patients need to surgically implant an artificial eye pedestal (such as a hydroxyapatite artificial eye pedestal) and then place an artificial eye lens in the conjunctival sac.

[0003] An artificial eye lens is a thin-shelled artificial false eye, on the surface of which an eyeball image (including cornea, sclera and its blood vessels, iris, and pupil, etc.) is drawn. Therefore, after being placed in the conjunctival sac, visually, the artificial eye lens is similar to the image and shape of a normal eyeball, thus improving the appearance of the patient.

[0004] Even so, many patients report the following defects in current artificial eye lenses: 1. The image drawn on the artificial eye lens is static and cannot move synchronously with a normal healthy eye, resulting in the situation of "the patient's normal eyeball moves while the artificial eye lens does not move", and the appearance is unnatural. 2. After wearing an artificial eye lens for a long time, the lower eyelid becomes loose, and even eversion or the artificial eye lens falls off may occur. The reason for this is that the artificial eye lens is placed in the conjunctival sac and will continuously press on the lower eyelid due to its weight. Especially for the early commercially available ceramic artificial eye lenses which are too heavy, lower eyelid relaxation, eversion, and artificial eye lens detachment often occur. Therefore, designing and manufacturing a light and thin-shelled artificial eye lens is a prerequisite for long-term and stable wearing of the artificial eye lens, and achieving synchronous movement of the artificial eye lens or its image with a normal eyeball is an important goal for further improving aesthetics and naturalness.

[0005] In view of the defect that the artificial eye lens cannot move, a patent with the publication number CN209154107U, "An artificial eye structure with a freely movable cornea", discloses an artificial eye lens with a cornea made of metal material, and a magnetic head is arranged in the artificial eye socket. The magnetic head exerts a magnetic adsorption effect on the cornea of the artificial eye lens. Through magnetic coupling, the metal cornea of the artificial eye lens moves with the rotation of the artificial eye socket and the magnetic head. However, this design has significant limitations in practical applications: 1. This system requires the implantation of a magnetic head in the central part of the artificial eye socket, increasing the weight of the artificial eye socket and causing the artificial eye socket to shift downward and become eccentric. 2. The contraction of the surgical scar may cause the central position of the artificial eye socket to shift, affecting the accuracy of magnetic coupling. 3. In order to achieve the simulation effect, the central axis of the magnetic head must be accurately aligned with the central axis of the normal eyeball; if the positioning is inaccurate, it will lead to asynchronous movement or strabismus of the two eyes. In clinical practice, it is extremely difficult to achieve this precise alignment, especially considering the various variables that may occur during the surgery and subsequent healing process. Therefore, although this technical solution has the potential for dynamic simulation in theory, in practical applications, achieving synchronous movement between the metal cornea of the artificial eye lens and the normal eyeball remains a highly challenging task.

[0006] In addition, a patent with the publication number CN110584835A, "Artificial Eye Display Device and Its Control Method", discloses that the movement and images of a normal eyeball (including the cornea, sclera, blood vessels, iris, and pupil, etc.) are obtained by video recording and displayed on the artificial eye lens display device, theoretically achieving binocular synchronous movement. However, this device has the following disadvantages: 1. This device requires an electronic artificial eye socket for support, which is large in size and heavy in weight, and cannot be placed into the eye socket with a surgically implanted artificial eye socket; even if it is placed into the eye socket without a surgically implanted artificial eye socket, due to its heavy weight, its stability is poor and it is easy to fall off. 2. If the electronic artificial eye socket in this patent is used as an implant and surgically implanted into the patient's eye socket, then, before it can be officially used clinically, it must undergo a series of strict experimental evaluations, including: biocompatibility, toxicology tests, animal experiments, phase III clinical trials, etc. The evaluation period is long, the cost is high, and it may even fail the clinical evaluation. 3. This device obtains the movement and images of a normal eyeball (including the cornea, sclera, iris, pupil, and blood vessels, etc.) by video recording, and then generates the movement and images on the artificial eye lens display device. The amount of data collected, transmitted, and displayed is extremely large, and there may be a large delay in its movement and images. At the same time, the hardware requirements for the system are high and the equipment is complex. It is difficult to miniaturize and lightweight the artificial eye lens display device.

[0007] Therefore, there is an urgent need in the art for a miniaturized and lightweight artificial eye lens display device to facilitate patients to wear it in the eye socket after eyeball removal, and without complications such as lower eyelid relaxation. Summary of the Invention

[0030] This application provides a preset image type artificial eye lens display device, which is connected to a camera device arranged on the side of a normal eyeball, and includes: an artificial eye lens substrate, a power source, and a display screen for displaying a preset eyeball image mounted on the artificial eye lens substrate; this device does not rely on an electronic artificial eye platform. The artificial eye lens display device adjusts the position of the preset eyeball image on the display screen by receiving the movement trajectory signal of the normal eyeball generated and sent by the camera device, and realizes synchronous movement with the normal eyeball visually. In the artificial eye lens display device of this application, by simplifying the movement trajectory signal and controlling the movement of the preset eyeball image, it not only realizes real-time synchronous movement with the normal eyeball, but also reduces the hardware requirements of the device, which is beneficial to the miniaturization and light weight of the artificial eye lens display device and improves the wearing stability of the artificial eye lens display device.

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the technical solutions in the embodiments of the present invention will be further described in detail through the following embodiments in combination with the drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the invention.

[0032] As Figure 1 shown, it is a schematic structural diagram of a wearable artificial eye lens display device in an embodiment of the present invention.

[0033] The wearable artificial eye lens display device is communicatively connected to a camera device 1 arranged on one side of a normal eyeball and includes:

[0034] An artificial eye substrate and an artificial eye display device 2 mounted on the artificial eye substrate;

[0035] Wherein, a micro antenna 21, a memory 22, a microprocessor 23, a display screen 24 and a power supply 25 are integrated in the artificial eye display device 2;

[0036] The power supply 25 is used to supply power to the micro antenna 21, the memory 22, the microprocessor 23 and the display screen 24;

[0037] The micro antenna 21 is used to receive the simplified motion trajectory signal of the normal eyeball generated and transmitted by the imaging device 1; the memory 22 is used to store the preset eyeball image and the preprocessed simplified motion trajectory signal of the normal eyeball;

[0038] The microprocessor 23 is used to generate a corresponding control signal based on the preprocessed simplified motion trajectory signal of the normal eyeball obtained from the memory 22;

[0039] The display screen 24 is used to adjust the position of the preset eyeball image displayed thereon based on the control signal generated by the microprocessor 23, so as to synchronously simulate the eyeball movement of the normal eyeball.

[0040] In an embodiment, the simplified motion trajectory signal of the normal eyeball includes: a fixation point coordinate information signal and an eyeball rotation angle information signal.

[0041] Specifically, the imaging device 1 is used to collect the image information signal of the user's normal eyeball in real time, and perform simplification processing on the collected image information of the normal eyeball to generate a simplified motion trajectory signal of the normal eyeball. The imaging device 1 sends the generated simplified motion trajectory signal of the normal eyeball to a preset image type artificial eye display device. The artificial eye display device receives the simplified motion trajectory signal of the normal eyeball through the micro antenna. After the artificial eye display device preprocesses the simplified motion trajectory signal of the normal eyeball, the microprocessor generates a corresponding control signal based on the simplified motion trajectory signal of the normal eyeball. The display screen adjusts the position of the preset image displayed on the display screen based on the control signal generated by the microprocessor, so that the preset image displayed on the display screen moves to the corresponding position, thereby realizing that the displayed eyeball image moves simultaneously, in the same direction and with the same amplitude as the normal eyeball movement.

[0042] It should be noted that in the present invention, the prosthetic eye substrate and the prosthetic eye display device 2 are integrated into a prosthetic eye. The shape, size and weight of this prosthetic eye are similar to those of traditional prosthetic eyes, and users can wear it directly. The reason for presetting and displaying the eyeball image on the display screen 24 is that the imaging device 1 can only send the motion trajectory signal related to the position adjustment of the normal eyeball image. Compared with the method of transmitting the complete eyeball image signal to the prosthetic eye display device for display, this method greatly reduces the data transmission volume between the imaging device 1 and the prosthetic eye display device, thereby reducing the hardware requirements of the prosthetic eye display device and meeting the technical index requirements of miniaturization and light weight of the prosthetic eye display device.

[0043] Another thing to note is that since the preset image type prosthetic eye display device of the present invention does not use an electronic prosthetic eye platform, the volume is effectively reduced, the mass is reduced, and the wearing stability of the prosthetic eye in the conjunctival sac is improved. Since the power supply is integrated in the prosthetic eye display device 2, the preset image type prosthetic eye display device of the present invention is safer and more reliable than the electronic display device used in combination with the electronic prosthetic eye platform.

[0044] As Figure 2 shown, a control method for presetting images in a prosthetic eye display device is presented, which is applied to the preset image type prosthetic eye display device as described above; the method includes:

[0045] Collect the normal eyeball image of the user. The eyeball image includes details such as the position, shape, size, color, and brightness of the cornea, sclera, iris, pupil, and blood streaks. Then store the image in the memory 22 of the prosthetic eye display device.

[0046] Receive the eyeball motion signal through the micro antenna 21. Perform preprocessing on the received eyeball motion signal, including filtering and amplification. The microprocessor 23 generates a corresponding control signal based on the preprocessed signal. Adjust the position of the preset image on the display screen 24 based on the control signal to achieve synchronous movement of the preset eyeball image and the normal eyeball.

[0047] In a specific embodiment, the forms shown by the preset eyeball image include but are not limited to: the form, color, and size of the cornea, the form, color, and size of the sclera, and the form, color, and size of the iris or pupil. Specifically, the cornea form and the iris form are represented as the black eye pupil; the sclera form is represented as the white eye pupil.

[0048] In a preferred embodiment, the preset eyeball image can also show details of the eyeball such as eye blood vessels. This can make the eyeball image displayed on the display screen closer to the real eyeball and improve the simulation degree. The eyeball image is collected from the user's real normal eyeball.

[0049] In one embodiment, as Figure 3 shown, a signal processing module 3 is further provided in the artificial eye lens display device; wherein, the signal processing module is respectively connected to the micro antenna 21, the memory 22, and the power supply 25; the signal processing module 3 is configured to preprocess the simplified motion trajectory signal of the normal eyeball generated by the micro antenna 21, and send the preprocessed simplified motion trajectory signal of the normal eyeball to the memory; wherein, the preprocessing includes signal amplification processing and filtering processing.

[0050] It should be noted that preprocessing the simplified motion trajectory signal of the normal eyeball before sending it to the microprocessor 23 has the advantage that, through amplification processing and filtering processing, the quality of the received motion trajectory signal of the normal eyeball can be improved, so that more accurate position adjustment can be performed on the displayed eyeball image.

[0051] In one embodiment, as Figure 3 shown, the signal processing module 3 includes: an amplification circuit 31 for amplifying the simplified motion trajectory signal of the normal eyeball received through the micro antenna; a filtering circuit 32 for filtering the amplified simplified motion trajectory signal of the normal eyeball to generate a preprocessed simplified motion trajectory signal of the normal eyeball.

[0052] It should be noted that the cut-off frequency of the filtering circuit can be adjusted by adjusting the component parameters in the filtering circuit.

[0053] In one embodiment, the method for generating the motion trajectory signal of the normal eyeball includes: real-time collecting the image information of the normal eyeball; preprocessing the collected image information of the normal eyeball; generating the simplified motion trajectory information of the normal eyeball based on the eyeball feature points extracted from the preprocessed image information of the normal eyeball.

[0054] In one embodiment, the real-time collection of the image information of the normal eyeball adopts the corneal reflection method: the image information of the normal eyeball is obtained by capturing the reflected light on the surface of the normal eyeball; wherein, the image information of the normal eyeball includes multiple frames of image data of the normal eyeball; each frame of image data of the normal eyeball includes: the position, shape, size, color, brightness, etc. of the pupil, the iris, the light spot, and the blood streaks.

[0055] It should be noted that the corneal reflection method is a method for capturing eyeball movement through the line connecting the corneal center and the pupil center.

[0056] In one embodiment, any one or more of image grayscale conversion, noise reduction, and image enhancement can be used to preprocess the collected normal image information.

[0057] In one embodiment, generating the simplified motion trajectory information of a normal eyeball based on the eyeball feature points extracted from the image information of the preprocessed normal eyeball includes: sequentially performing edge detection and feature extraction on the image information of the preprocessed normal eyeball to obtain the eyeball feature points; performing eyeball motion analysis based on the obtained eyeball feature points to generate motion trajectory information; wherein, the specific process of the eyeball motion analysis includes: analyzing the change in the pupil center position of the normal eyeball in these two frames based on the eyeball feature points extracted from the image information of the normal eyeball in the Nth frame and the (N + 1)th frame to generate the simplified motion trajectory information of the normal eyeball.

[0058] It should be noted that the simplified algorithm for the normal eyeball motion trajectory can perform edge detection using, including but not limited to, Roberts operator, Prewitt operator, Sobel operator, Canny operator, or Laplacian operator, etc., and can perform feature extraction using HOG features, LBP features, and Haar features, etc.

[0059] Another thing to note is that in order to reduce the amount of data during data processing and transmission, reduce or avoid image delay, any eyeball feature point can be extracted from the image information of the normal eyeball for continuous frame analysis; considering the interference caused by eyelid occlusion or blinking during human eye movement to eyeball feature extraction, the selection of the eyeball feature point includes, but is not limited to, any one of the following: the pupil center point, the left and right endpoints of the pupil, the lower endpoint of the pupil, the left and right endpoints of the iris, and the lower endpoint of the iris or other feature points.

[0060] In one embodiment, the methods that can be used for continuous frame analysis of normal eyeball motion include, but are not limited to, pupil positioning and optical flow estimation.

[0061] It should be noted that algorithms such as HS optical flow method, Lucas-Kanada method, Pyramidal LK method, etc. can be used for optical flow estimation.

[0062] In one embodiment, generating the corresponding control signal based on the simplified motion trajectory signal of the preprocessed normal eyeball obtained from the memory includes: performing denoising, demodulation, and decoding processing on the simplified motion trajectory signal of the preprocessed normal eyeball obtained from the memory to extract useful information; converting the processed eyeball motion signal into a control signal.

[0063] In one embodiment, the base material of the artificial eye lens includes, but is not limited to, any one of the following: ultra-thin glass, ceramics, hydrogel, polymethyl methacrylate (PMMA), polyethylene (PE), and polyvinyl chloride (PVC), etc.

[0064] In one embodiment, the present invention can use hydrogel material to make a soft artificial eye lens according to the usage situation of the user.

[0066] In one embodiment, the battery adopts any one of the following, including but not limited to: lithium - manganese button battery, lithium - ion button battery, small lithium battery, solar battery, button battery, wireless charging battery, etc.

[0067] It should be noted that since the battery is integrated in the preset image - type artificial eye display device, the battery needs to be small, easy to replace or easy to charge. Those skilled in the art can adopt other types of batteries with the above - mentioned characteristics, and the present invention does not limit this.

[0068] In one embodiment, the preset image - type artificial eye display device is further configured to send a feedback signal for power - on / off judgment to the imaging device after receiving the simplified motion trajectory signal of the normal eyeball generated by the imaging device.

[0069] Specifically, if the imaging device does not receive the feedback signal sent by the wearable preset image - type artificial eye display device, it is determined that the preset image - type artificial eye display device is in a power - off state; if the imaging device receives the feedback signal sent by the preset image - type artificial eye display device, it is determined that the preset image - type artificial eye display device is in a power - on state.

[0070] In a specific embodiment, the imaging device can be a frame - type device equipped with a micro camera.

[0071] In one embodiment, the display screen can adopt any one of the following, including but not limited to: organic light - emitting diode (OLED), micro light - emitting diode (micro LED), transmissive / reflective display panel, E - ink display screen, etc.

[0079] In addition, any connection may be appropriately referred to as a computer-readable medium. For example, if instructions are sent from a website, a server, or other remote sources using coaxial cables, fiber optic cables, twisted pairs, digital subscriber lines (DSLs), or wireless technologies such as infrared, radio, and microwave, then the coaxial cables, fiber optic cables, twisted pairs, DSLs, or wireless technologies such as infrared, radio, and microwave are included in the definition of the medium.
