support leg

102 and 103 and the back surface of the color chart 101 may be 90 degrees (i.e. the

support legs

102 and 103 are perpendicular to the back surface of the color chart 101 as shown in fig. 1), an obtuse angle greater than 90 degrees (i.e. as shown in fig. 2) may also be provided, and the length of the support leg 102 is shorter than the length of the support leg 103, the support leg 102 is used for supporting the upper eyelid (as shown in fig. 4) of the eyelid 20, and the support leg 103 is used for supporting the lower eyelid (as shown in fig. 4) of the eyelid 20. The support ends 102a of the support legs 102 (i.e., the ends of the support legs 102 against the upper eyelid) and the support ends 103a of the support legs 103 (i.e., the ends of the support legs 103 against the lower eyelid) are smooth and have outwardly spaced apart heel brace structures to avoid damage to the eyelid.

Also, when the color chart 101 is a separately fabricated component with respect to all of the support legs, the ends of all of the support legs for connecting the color chart 101 may be integrally connected to each other so that all of the support legs form an integral support frame component, or any two of the support legs are separated from each other so that each of the support legs is a separate component.

With continued reference to fig. 1, in the present embodiment, the jaundice analysis module 11 includes a camera 111 and an image analysis module 112. The color blocks 101a to 101g on the front surface of the color chart 101 and the eye sclera exposed by the through hole 1011 can be simultaneously taken into the field of view of the camera 111, so that the camera 111 can be used for shooting one image from the front surface of the color chart 101 to the color blocks 101a to 101g on the color chart 101 and the eye sclera in the through hole 1011.

In this embodiment, the jaundice analysis module 11 further includes an illumination light-compensating module 113, where the illumination light-compensating module 113 is configured to illuminate and compensate light of the photographed area (i.e. the through hole 1011 and the color blocks 101 a-101 g) of the color chart 101 according to the condition of ambient light in the process of photographing the image by the camera 111.

Optionally, the illumination light-compensating module 113 includes at least one LED light-compensating lamp (not shown), and during the process of capturing an image by the camera 111, the on-off and brightness of each LED light-compensating lamp are controlled according to the condition of ambient light, so as to illuminate and compensate light in the captured area.

In this embodiment, the image processing module 112 may be configured to determine whether each image captured by the camera 111 meets the detection requirement, and further perform color correction on the image meeting the detection requirement, so as to analyze and compare the color of the color block in the color corrected image with the color of the sclera of the eye, thereby obtaining the jaundice detection result.

In another embodiment of the present invention, when the illumination light compensating module 113 has a display screen, the illumination light compensating module 113 is configured to control the display screen to display background pictures with different colors and pure colors without patterns according to the condition of ambient light in the process of capturing images by the camera 111, so that the camera 111 captures images under illumination of a plurality of different background pictures. The image processing module 111 is configured to correct and analyze the images under the illumination of the plurality of different background pictures, and select an optimal corrected image from the images, so as to analyze and compare the color of the color block in the optimal image and the color of the sclera of the eye, thereby obtaining a jaundice detection result.

In this embodiment, the image analysis module 111 may be locally disposed or may be disposed on a cloud server. When the image analysis module 111 is disposed on the cloud server, each image captured by the camera 111 is uploaded to the cloud server, and then the cloud server analyzes and evaluates the images to obtain a jaundice detection result and returns the jaundice detection result to the local for the user (including the patient and/or doctor) to view.

The jaundice detection module 11 is integrated into a portable mobile device with a small size and convenient portability, and when the image analysis module 111 is disposed on the cloud server, the jaundice detection module 11 further needs to include a network communication module that is disposed locally and can communicate with the cloud server, so that a user can use the device conveniently, and the jaundice detection module 11 is formed by, for example, adopting front and rear cameras of the portable mobile device such as a smart phone and a PAD.

In addition, the jaundice detection module 11 may be designed as a new stand-alone medical device, or may be integrated into an existing portable mobile device such as a mobile phone, smart band, smart eye, blood glucose meter, oximeter, electronic blood pressure agent, etc.

The following results are shown in fig. 4 to 5, and take the example that the color correction module 10 has two

support legs

102 and 103 as an example, to describe in detail the image acquisition and analysis process for implementing jaundice detection by the jaundice detection device of the present embodiment, specifically as follows:

firstly, the color chart 101 of the color chart 11 is placed in front of eyes of a user, the front surface of the color chart 101 faces the camera 111 of the jaundice detection module 11, the supporting end 102a of the short supporting leg 102 on the back surface of the color chart 101 is propped against the upper eyelid 202 of the eye 20, the supporting end 103a of the long supporting leg 103 on the back surface of the color chart 101 is propped against the lower eyelid 201 of the eye 20, the color chart 101 is slightly pressed, the supporting

legs

102 and 103 deform, the upper eyelid 202 and the lower eyelid 201 of the eye 20 are propped up to a proper position, at this time, the included angle θ' between the supporting

leg

102 or 103 and the back surface of the color chart 101 can be smaller or larger than the corresponding included angle θ before the use of the color chart 11, and the through hole 1011 of the color chart 101 exposes the sclera 203 of the eye 20. And at this time, the sclera 203 and the respective color patches 101 a-101 g on the front side of the color chart 101 are simultaneously brought into view of the camera 111 in the jaundice analysis assembly 11. Thereby determining a photographed region.

Then, the camera 111 of the jaundice analysis module 11 photographs the color patches 101a to 101g on the front surface of the color chart 101 in the visual field and the sclera 203 exposed through the through-hole 1011, thereby obtaining a corresponding image. And in each shooting process of the camera 111, the illumination light-compensating module 113 can be controlled to illuminate and compensate light to the shot area according to the condition of ambient light, so as to ensure the quality of the shot image. When the illumination light-compensating module 113 is an LED light-compensating lamp, the on-off and brightness of the LED light-compensating lamp can be controlled according to the ambient light conditions during the shooting process of the camera 111, so that the shot area has enough illuminance to ensure the quality of the shot image. When the illumination light-compensating module 113 is a display screen, in the shooting process of the camera 111, the purpose of illumination light compensation is achieved by displaying a pure-color non-pattern background on the display screen, and simultaneously, the purpose of illumination light compensation can be achieved by displaying pure-color non-image background pictures with different colors on the display screen in a time-sharing manner, so that the shot areas are respectively shot based on the background pictures with different colors, and a plurality of images with different color resolutions are obtained.

After the camera 111 finishes shooting, the jaundice detection application program in the image analysis module 112 first judges whether each image shot by the camera 111 meets the detection requirement, and an internal algorithm of the jaundice detection application program further performs color correction on the image meeting the detection requirement, and compares and analyzes colors of color blocks and sclera in the image after the color correction, so as to obtain (or evaluate) a corresponding bilirubin level, namely, a jaundice detection result is obtained.

Finally, the jaundice detection result can be fed back to the user in a display screen, a paper report or voice broadcasting mode and the like.

Of course, in other embodiments of the present invention, when the image processing film 112 is disposed on the cloud server, each image captured by the camera 111 may be uploaded to the cloud server, and then the image processing film 112 of the cloud server performs similar image processing and comparison analysis, and obtains a corresponding jaundice detection result, and further returns the obtained jaundice detection result to the local and timely feeds back to the user.

In addition, when the illumination light-compensating module 113 has a display screen and the camera shoots the shot region based on the solid-color non-image background images with different colors displayed on the display screen in a time-sharing manner, so as to obtain multiple images with different color resolutions, the local or cloud image processing module 112 may perform one-to-one color correction on each of the multiple images with different color resolutions, select an optimal image from the multiple images with different color resolutions, and further perform comparison and analysis on the color of the color block and the sclera in the optimal image to obtain a corresponding bilirubin level (i.e. obtain a jaundice detection result), or the local or cloud image processing module 112 may perform fusion and image enhancement on the multiple images with different color resolutions according to the color of the background image in the multiple images with different color resolutions, so as to obtain an enhanced image (i.e. multiple original images are synthesized into one enhanced image), and further perform comparison and analysis on the color block and the color of the sclera in the enhanced image to obtain a corresponding bilirubin level (i.e. obtain a jaundice detection result).

It should be understood that the supporting component in the above embodiments is described by taking a mechanism with a plurality of supporting legs as an example, but the technical solution of the present invention is not limited thereto, and the supporting component may be a hollow truncated cone-shaped structure, as long as the supporting component can support the color chart and separate the upper eyelid and the lower eyelid, so that the shot area includes each color lump on the color chart and the sclera exposed by the through hole of the color chart.

In summary, the jaundice detection device provided by the invention has a simple structure, does not need laboratory equipment, does not need blood drawing, has no pain, no wound or infection risk, can be conveniently used by families and hospitals, can reduce the cost of jaundice detection, evaluates bilirubin level through images of the sclera of eyes, and can also avoid the problem that the jaundice detection result is inaccurate or inconsistent due to different complexion of users. Further, when using the camera to shoot, can carry out illumination light filling according to ambient light, strengthen jaundice detection accuracy, avoid because external light difference leads to the testing result deviation.

In addition, based on the above-mentioned jaundice detection process, an embodiment of the present invention further provides an image processing method of a jaundice detection device, where the jaundice detection device is preferably, but not limited to, the jaundice detection device of the present invention.

The image processing method of the jaundice detection device of the present embodiment is implemented after determining a photographed area, where the photographed area includes each color lump on the color chart and a sclera exposed by a through hole of the color chart, and the method can be implemented by supporting the color chart by a supporting component and separating an upper eyelid and a lower eyelid. Specifically, the image processing method of the present embodiment includes the steps of:

When the shot area is illuminated and supplemented by the illumination according to the condition of the ambient light, the shot area after the light supplement of the different background images is imaged to obtain a plurality of images which are illuminated by the different background images and contain color blocks and sclera. Thus, the steps of performing image processing on the corresponding image obtained by shooting, and performing analysis and comparison on the color of the color block and the sclera in the corresponding image after the image processing may further include: respectively carrying out color correction and analysis on a plurality of images under the illumination of different background pictures, selecting an optimal image after the color correction from the images as a corresponding image after the image processing, and further carrying out analysis and comparison on the color of a color block and the color of a sclera in the optimal image; or fusing and enhancing the photographed images under the illumination of a plurality of different background pictures to obtain enhanced images serving as corresponding images after image processing, and further analyzing and comparing the color of the color block and the color of the sclera in the enhanced images.

Optionally, in the image processing method, when a plurality of images including color patches and sclera are obtained by shooting, it is first determined whether each of the shot images meets a detection requirement to select an image meeting the detection requirement therefrom, and then at least one of the selected images meeting the detection requirement is subjected to image processing to obtain a corresponding image after the image processing.

Based on the same inventive concept, an embodiment of the present invention further provides a storage medium, on which a computer program (which may be an instruction, an algorithm, or an encoding program, etc.) is stored, where the computer program, when executed by a processor, is configured to implement the image processing method of the jaundice detection apparatus according to the present invention. The storage medium may be any medium capable of containing, storing, transmitting, propagating or transmitting the computer program. For example, the storage medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium, specific examples of which include a magnetic storage device such as a magnetic tape or hard disk (HDD); optical storage devices such as Compact Discs (CDROM); a memory, such as a Random Access Memory (RAM) or a flash memory; and/or wired, wireless communication links.
