In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 3, the application package may include applications such as camera, gallery, calendar, phone call, map, navigation, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 3, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

For example, prompting text information in the status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The following describes exemplary workflow of the software and hardware of the electronic device 100 in connection with capturing a photo scene.

When the touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation, and taking a control corresponding to the click operation as a control of a camera application icon as an example, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera drive by calling a kernel layer, and captures a still image or a video through the camera 193.

The first embodiment is as follows:

when a user needs to detect the skin, the method can be realized by the following three ways:

mode 1: skin detection is performed by a skin detection device. The skin detection device may be a medical skin detection device, which is usually purchased by medical institutions due to factors such as counterfeit cost and device volume, and when a user needs to perform skin detection through the skin detection device, the user generally needs to go to the corresponding medical institution to perform skin detection, and the output skin detection report mainly provides various index values of the skin detection, such as melanin content, acne density, roughness, tissue oxygen content, skin type classification (such as oily skin or dry skin), and the user can obtain the whole skin state through the skin detection report. However, the above method has a high detection difficulty, and because the skin detection device has a high manufacturing cost, the user is difficult to purchase the device at home, and the user needs to go to a medical institution for detection, so that the difficulty and cost of skin detection are greatly increased. Moreover, the skin detection device cannot acquire the local skin state, and the display effect of the report is poor. On the other hand, the detection device has long data processing time and low real-time performance, and needs a user to wait for a long time to obtain a detection report, so that the report acquisition efficiency is low.

Mode 2: skin detection is performed through the intelligent beauty mirror. The existing intelligent makeup mirror generally only has the functions of beautifying and whitening skin, namely beautifying human face and not having the function of skin detection. In the process of face beautification, freckles, dark circles and the like of the face can be recognized through an intelligent recognition algorithm, and the treatment such as beautification, blurring, whitening and the like is carried out on the flaw areas. Exemplarily, fig. 4 shows a schematic diagram of an output screen of the intelligent cosmetic mirror provided by an embodiment of the present application. Referring to fig. 4, the intelligent cosmetic mirror can identify the human face defect area and mark the human face defect area so that the user can know the current skin condition. However, the existing intelligent cosmetic mirror cannot determine the skin sensitivity, has fewer skin detection items, and cannot meet the skin detection requirements of the existing users.

Mode 3: and carrying out skin detection through an application program on the smart phone. Similar to skin detection through an intelligent makeup mirror, a smart phone with the application program often only can perform skin beautifying and whitening treatment on an image with a face of a user and identify flaws of the face of the user, skin sensitivity cannot be determined, skin detection items are few, and skin detection requirements of the existing user cannot be met.

Therefore, the three modes cannot simultaneously consider two aspects of efficiently acquiring the skin sensitivity detection result and knowing the local sensitivity distribution of the skin. Therefore, in order to solve the above-mentioned drawbacks of the skin detection technology, the present application provides a method for displaying skin sensitivity, which is described in detail as follows: referring to fig. 5, an executing subject of the skin sensitivity display method is an electronic device, which may be any one of a smart phone, a tablet computer, a smart game machine and a device configured with a camera module, and optionally, the electronic device may be a smart mirror, the camera module loaded on the smart mirror is used to acquire a user image including the user using the smart mirror, the user image is processed by a processor, and the processed user image is output on a "mirror surface" (i.e., a display module) of the smart mirror, so as to simulate a scene where the user looks at the mirror, and adjust a picture presented by the "mirror surface" according to a user's requirement. Fig. 5 shows a flowchart of an implementation of a method for displaying skin sensitivity according to an embodiment of the present application, which is detailed as follows:

in S501, an original image containing a photographic subject is acquired, and a skin area image of the photographic subject is extracted from the original image.

In this embodiment, the electronic device may be provided with a built-in camera module, the camera module is used to obtain an original image including a subject, and the subject may move a region to be detected into a shooting area of the electronic device, so that the skin region including the region to be detected is included in the original image obtained by shooting. Exemplarily, fig. 6 shows a schematic view of a scene of an electronic device acquiring an original image according to an embodiment of the present application. Referring to fig. 6, the electronic device is specifically an intelligent mirror, the intelligent mirror can be placed on a desktop, and when a user is in a sitting posture, the intelligent mirror can shoot the face of the user, in this scene, the shooting object is the user, and the skin area to be detected is the skin area of the face.

In one possible implementation manner, the electronic device may receive an original image fed back by an external camera module. The electronic equipment can be in communication connection with an external camera module through a wired interface or a wireless communication module, and receives an original image which is acquired by the camera module and contains a shooting object. The camera module may be a camera module specially used for skin detection, for example, a camera equipped with a plurality of different light emitting devices, and may emit violet light, red light, ultraviolet light, infrared light, and the like through the different light emitting devices. The camera module can acquire original images of a shooting object under different light irradiation, and feeds back the shot original images to the electronic equipment through a communication link between the camera module and the electronic equipment. Some skin detection methods, such as skin sensitivity detection or acne density, may require a subject to capture an original image under specific light irradiation, and based on this, the camera module may configure a plurality of different light emitting devices according to the requirements of detection items, so that when a corresponding skin detection item is performed, the associated light emitting device is turned on, and the subject is irradiated under corresponding light to obtain the original image.

In a possible implementation manner, the electronic device may select the captured image from the gallery as the original image. Fig. 7 illustrates a selection interface diagram of an original image according to an embodiment of the present application. Referring to fig. 7 (a), the electronic device may enter a gallery display interface, such as fig. 7 (b), upon detecting that the user clicks on the gallery control 701. The method comprises the steps that images which are shot or obtained from other equipment can be displayed in a gallery display interface of the electronic equipment, when the electronic equipment detects that preset selecting operation is initiated on any existing image, the existing image is used as a target image, a skin sensitivity display process is carried out on the target image, the target image is used as the original image, and the operations from S501 to S503 are carried out. For example, the preset selecting operation may be a long-press operation, and if it is detected that the user performs the long-press operation on any existing image, a control 702 as in (c) in fig. 7 is popped up, where the control 702 is specifically an edit menu executable for the existing image, and the edit menu includes a "skin sensitivity detection" item, that is, a control 703, and if the electronic device detects that the user clicks the control 703, a skin sensitivity display process is executed; for another example, when the electronic device detects that the user clicks any existing image, a preview page of the existing image may be displayed, as shown in fig. 7 (d), the preview page includes a plurality of editing controls, including a control 704 for detecting skin sensitivity, and when the electronic device detects that the user clicks the control 704, the electronic device may execute a display process of a skin sensitive area to output a sensitivity distribution diagram corresponding to the existing image previewed by the user.

In one possible implementation, the electronic device may configure a plurality of display modes, which include but are not limited to: a normal display mode and a sensitivity detection mode. If the electronic equipment is in the normal display mode, the original image can be directly displayed and output, namely, other processing on the original image is not needed; in the sensitivity detection mode, it indicates that the user needs to view the skin sensitivity of the user, and at this time, the operations from S501 to S503 are performed to display the sensitivity distribution image corresponding to the original image.

In a possible implementation manner, the electronic device may obtain real-time video data including a photographic object, where the real-time video data is specifically data obtained by a camera module through shooting at a preset frame rate, each frame corresponds to one image, and the electronic device may extract each video image frame from the video data, and perform a skin sensitivity display process on each video image frame, that is, perform operations from S501 to S503, and output a sensitivity distribution diagram corresponding to each video image frame, so as to implement real-time dynamic observation of the skin sensitivity of the photographic object, and improve the display effect and the real-time performance of the skin sensitivity.

Further, when the electronic device acquires real-time video data, S501 may specifically include S5011 to S5012, which are detailed as follows:

in S5011, video data acquired in real time is acquired.

In this embodiment, the electronic device is configured with a camera module, the camera module may acquire video data, and the camera module may acquire video data of a shooting object in real time through the camera module, and transmit the video data acquired in real time to a processor of the electronic device for processing, for example, performing display processing of skin sensitivity. It should be noted that, since the camera module acquires video data of a shot object in real time, after each frame of video image is acquired, the camera module transmits newly-added acquired video data to a processor of the electronic device for processing, that is, in the process of acquiring video data in real time, the acquired video data is also processed in subsequent steps in real time, and the processed video data is displayed on the display module, so as to achieve the purpose of dynamically checking the skin sensitivity in real time.

In a possible implementation manner, the camera module generates a video data stream, encapsulates the video data acquired in real time into data packets of corresponding formats, and transmits the data packets of the acquired video data in real time through the video data stream so as to process the video data in real time.

In S5012, each video image frame within the video data is extracted as the raw image.

In this embodiment, after obtaining the video data, the electronic device may analyze the video data, extract each video image frame included in the video data, and use the obtained video image frame as the original image to generate a sensitivity distribution diagram corresponding to each video image frame.

In the embodiment of the application, the electronic device can acquire the video data of the target object in real time, and respectively display and process the skin sensitivity of each video image frame in the video data to obtain the sensitivity distribution schematic diagram corresponding to each video image frame, so that a user can check the skin sensitivity condition in real time, the display effect of the skin sensitivity is improved, the checking real-time performance is improved, and the use experience of the user is improved.

Further, as another embodiment of the present application, fig. 8 is a flowchart of a specific implementation of S5012 provided in an embodiment of the present application. Referring to fig. 8, compared with the previous embodiment, S5012 in the embodiment of the present application specifically includes S801 to S803, which are specifically described as follows:

further, the extracting each video image frame within the video data as the raw image comprises:

in S801, image analysis is sequentially performed on the original image based on the frame number, and it is determined whether or not a skin region is included in the original image.

In this embodiment, when the electronic device obtains the video data of the shooting object in real time, a frame number is associated with each video image frame according to the sequence of the shooting time, and each video image frame is sequentially processed based on the frame numbers. In this embodiment, since the original image of the sensitivity distribution diagram is displayed, an image including a skin region is necessarily required, and if the original image does not include the skin region, the original image does not need to be processed; on the contrary, if the skin area is included in the original image, it is necessary to extract an area image corresponding to the skin area from the original image and perform the operations of S502 and S503.

In one possible implementation, the electronic device may be configured with a skin recognition algorithm, the electronic device imports an original image into the skin recognition algorithm, and may output a corresponding recognition result about the original image, where the recognition result includes: a first result comprising an area of skin and a second result not comprising an area of skin. The electronic device may determine to perform the operation of S802 or S803 according to the above recognition result.

In one possible implementation, the skin identification algorithm is embodied as a convolutional neural network. The electronic device may sequentially import each original image into the convolutional neural network based on the frame number, where the convolutional neural network may perform a plurality of convolutional operations on the original image through a plurality of cascaded convolutional kernels that are built in the convolutional neural network, to obtain N layers of convolutional vectors, where N is specifically the number of convolutional layers included in the convolutional neural network, each convolutional layer corresponds to one convolutional kernel, and import the convolutional vector output by the nth layer into a corresponding fully-connected layer, to identify whether the original image includes a skin region, so as to obtain an identification result. The electronic equipment extracts the features of the original image through the multiple convolution layers to judge whether the original image contains feature information related to the skin or not, so that whether the skin area is contained or not is identified.

In a possible implementation manner, the color of the skin is within a specific interval range, and the skin area has the characteristics of large area, flat picture and the like. Based on the two points, the electronic device can judge whether the pixel value of each pixel point in the original image is in the preset interval range or not according to the pixel value of each pixel point in the original image, if so, the number of the pixel points in the interval range is counted, whether the pixel points in the interval range are adjacent or not is judged, and if the number of the adjacent pixel points is larger than the preset number threshold value, the original image is identified to contain the skin area.

In a possible implementation manner, the electronic device may obtain an ambient light intensity when the original image is shot, perform light intensity compensation on each pixel value in the original image based on the ambient light intensity, and perform the identification operation in the above range according to the adjusted original image, so as to avoid color cast of the pixel value in the original image due to too bright or too dark ambient light intensity, so that the pixel value in the skin region deviates from the above range, thereby improving the accuracy of skin region identification.

In S802, if the original image includes a skin area, an operation of extracting a skin area image of the subject from the original image is performed.

In this embodiment, if the electronic device detects that the original image corresponding to the current frame number contains a skin area, a skin area image associated with the skin area may be extracted from the original image.

In S803, if the original image does not include a skin region, the original image corresponding to the next frame number is analyzed, and the operation of determining whether the original image includes a skin region is performed.

In this embodiment, when the electronic device detects that the original image corresponding to the current frame number does not include the skin region, it is not necessary to generate the sensitivity distribution diagram corresponding to the original image, and acquire the original image of the next frame number, and perform the operation of identifying the skin region.

In a possible implementation manner, if it is detected that the original image corresponding to the current frame number does not include a skin region, the original image is directly displayed.

In the embodiment of the application, before determining the skin sensitivity of an original image, firstly, judging whether the original image contains a skin region, and not performing the conversion operation of a sensitivity distribution schematic diagram on the original image not containing the skin region; only the original image containing the skin area is processed, thereby reducing unnecessary processing operations and improving the conversion efficiency.

In this embodiment, the electronic device may recognize an area covered by the skin of the photographic subject in the original image, that is, the skin area image described above, and extract the skin area image from the original image. Since the main recognition object is the skin area of the photographic subject when determining the skin sensitivity, sensitivity recognition is not required for other areas of the skin other than the photographic subject.

In one possible implementation, the electronic device may determine the skin region image by: extracting a plurality of contour curves contained in the original image through a contour recognition algorithm, and determining an image characteristic value of each image area based on the image area enclosed by each contour curve, wherein the image characteristic value comprises but is not limited to at least one of the following: average pixel value, number of pixels, mean square error of pixel values, etc. If the image characteristic value meets the preset skin characteristic condition, the image area enclosed by the contour curve is identified as a skin area, and the skin area image is extracted from the original image.

In one possible implementation, the electronic device may determine the skin area image by: the method comprises the steps of performing sliding framing on an original image through an image frame with an initial size, identifying whether an area currently covered by the image frame contains a skin area or not in the sliding framing process, marking the area if the area contains the skin area, obtaining the area containing a plurality of marks after the sliding framing is finished, reducing the image frame based on a preset adjustment step length, performing framing identification operation on the areas containing the marks until the size of the image frame is smaller than a preset lower limit threshold, and obtaining a skin area image in the last marked area.

Exemplarily, fig. 9 shows an extraction schematic diagram of a skin region image provided by an embodiment of the present application. Referring to fig. 9 (a), the original image is specifically an image including a hand region, and profile information corresponding to a skin region image included in the original image is determined by a preset skin region identification algorithm, that is, as shown in fig. 9 (b); and extracts a skin region image, i.e., (c) in fig. 9, from the original image based on the contour information.

In S502, skin sensitivities corresponding to respective pixel points within the skin region image are determined.

In this embodiment, the electronic device may be configured with a conversion algorithm of skin sensitivity, and each pixel point in the skin region image in the original image is imported into the conversion algorithm, so as to calculate the skin sensitivity corresponding to each pixel point.

In this embodiment, the original image of the photographic subject is obtained through any one of the camera modules, that is, the reason why the sensitivity of the skin region can be determined is specifically: the skin sensitive areas show a reddish appearance in clinical external skin manifestations. Skin sensitivity is generally caused by internal and external factors such as irritation by drugs, topically applied agents or environmental components. It is becoming increasingly important to understand the physiological response of the skin to these irritants in skin tests, medical studies and clinical drug studies, and skin tissue activity tests are the ability of the microvascular network of skin tissue to respond to vasodilation to increase blood flow and vasoconstriction to decrease blood flow, and thus to understand the allergic stiffness, inflammatory processes and irritation of the skin to irritants. Among them, skin sensitivity can be specifically classified into the following three types:

1. sensitive skin: the sensitivity is a skin normality, which means that the skin has high sensitivity, weak resistance to the outside and obvious reaction after being stimulated. For example, when the stratum corneum of the skin is damaged due to external environmental influences, incorrect use of cosmetics, excessive cleansing, etc., the barrier function of the skin is insufficient, the skin hydration degree is low, and therefore the skin is thin and fragile, and subcutaneous capillaries are dilated.

2. Skin irritation: also called irritant contact dermatitis, which is a phenomenon that skin is rapidly red, swollen, hot, painful and itchy after being stimulated by chemical irritants at or above a critical concentration. For example, exposure to excessive stimuli in a short period of time causes epidermal damage, barrier disruption, triggers cellular stress and immune responses, and activates inflammation.

3. Skin allergy: also called allergic contact dermatitis, it is a phenomenon that red, swollen, hot, painful, itchy etc. are produced in a short time after the skin is affected by allergen. Because the antigen is contacted with the skin for the first time to induce sensitization immunity, T cells can react after a period of time; allergic contact dermatitis occurs in a short time after sensitization, as in the principle of secondary contact resistance. Skin allergy is caused by an abnormal immune reaction triggered by chemicals, while low molecular weight chemicals (haptens) are the main cause of skin allergy, which also leads to subcutaneous telangiectasia.

Any of the above skin sensitivity phenomena is accompanied by subcutaneous telangiectasia, i.e. the skin surface shows a reddish appearance, so that the skin sensitivity of the shooting object can be determined by judging the reddish appearance of the skin surface of the user.

In a possible implementation manner, when calculating the skin sensitivity, it is necessary to determine the red, green, and blue channel values of each pixel point, that is, the skin area image is specifically an RGB image. Based on this, the terminal device may identify the image format of the skin area image, determine whether the image format is an image in RGB format, if so, execute the operation of S502; otherwise, the skin area image may be converted into RGB format by an image format conversion algorithm, and the operation of S502 is performed based on the converted skin area image.

In a possible implementation manner, the manner for the electronic device to determine the skin sensitivity corresponding to each pixel point may be: the electronic device can store a mapping relation between the skin sensitivity and the pixel value, and the electronic device can lead the pixel value of the pixel point into the mapping relation, so that the skin sensitivity corresponding to the pixel point can be obtained through calculation.

In a possible implementation, the skin sensitivity may be used in particular for characterizing the type of sensitivity, i.e. in particular skin allergy, skin irritation or sensitive skin, etc., according to three different classifications of the skin sensitivity. The electronic equipment configures corresponding sensitivity values for different skin sensitivity types, and if the sensitivity type of the random shadow of any pixel point is detected, the sensitivity value associated with the sensitivity type is used as the skin sensitivity of the pixel point.

As another embodiment of the present application, fig. 10 shows a flowchart of a specific implementation of S502 provided in an embodiment of the present application. Referring to fig. 10, compared to the embodiment shown in fig. 5, S502 in this embodiment specifically includes S5021 to S5022, which are detailed as follows:

further, the determining the skin sensitivity corresponding to each pixel point in the skin region image includes:

in S5021, a first pixel value corresponding to the pixel point in a red channel and a second pixel value corresponding to a green channel of the original image are obtained.

In the embodiment, the red blood cells of the blood capillaries in the skin tissue have the characteristic of strongly absorbing green light, and have little absorption on red light, while the subcutaneous dermal layer tissue has little absorption on light with various wavelengths in contrast, so that the detection of the heme by visible light can be realized; sensitive skin tends to develop redness, which is caused by the high number of red blood cells in the capillaries. Based on this, the electronic device can take an image of the skin area of the photographic subject under illumination light containing green and red light (e.g., white light or red-green polarized light, etc.), and determine the skin sensitivity based on the pixel values of the respective skin areas in the green channel and the red channel.

In this embodiment, the original image is specifically an RGB image, that is, each pixel point in the original image corresponds to one pixel value in each channel, which is a first pixel value of a red channel, a second pixel value of a green channel, and a third pixel value of a blue channel. The absorption degree of the green light and the red light of the skin corresponding to each pixel point in the skin area image needs to be determined, so that a first pixel value of a red channel and a second pixel value of a green channel are obtained.

In S5022, the first pixel value and the second pixel value are imported into a preset sensitivity conversion algorithm to obtain the skin sensitivity corresponding to the pixel point.

In this embodiment, the electronic device may import the obtained first pixel value and the obtained second pixel value into a sensitivity conversion algorithm, and determine the skin sensitivity of the skin area corresponding to the pixel point. If the absorption degree of the skin area corresponding to the pixel point to the red light is less, the first pixel value corresponding to the pixel point is larger, that is, the skin sensitivity and the first pixel value are in a positive correlation; if the skin area corresponding to the pixel point has a higher absorption degree for green light, the second pixel value corresponding to the pixel point is smaller, i.e. the skin sensitivity is in a negative correlation with the second pixel value.

In a possible implementation manner, the sensitivity conversion algorithm may be a hash conversion function, and the skin sensitivity corresponding to the pixel point may be obtained by importing the first pixel value and the second pixel value into the hash conversion function.

In a possible implementation manner, the sensitivity transformation algorithm may be obtained by training a neural network based on a plurality of training images. The electronic device may use red layers and green layers in the plurality of training images as input of the neural network, use the sensitivity training distribution map corresponding to the training images as output of the neural network, train the neural network, use the trained neural network as the sensitivity conversion algorithm, introduce the first pixel value and the second pixel value corresponding to each pixel point into the sensitivity conversion algorithm of the merchant, and calculate the skin sensitivity corresponding to each pixel point.

Further, the sensitivity conversion algorithm specifically includes:

In this embodiment, the electronic device may determine, according to a difference between a first pixel value of a red channel and a second pixel value of a green channel, an absorption deviation for red light and green light between the first pixel value and the second pixel value, so as to determine a concentration of red blood cells in a skin area corresponding to the pixel point, and determine a skin sensitivity of the skin area based on the concentration of red blood cells, thereby improving an accuracy of the skin sensitivity.

In the embodiment of the application, according to the characteristic that red blood cells absorb light of different colors, the first pixel value of the red channel and the second pixel value of the green channel are determined, so that the skin sensitivity corresponding to the pixel points is obtained, the acquisition difficulty of the skin sensitivity is reduced, and the accuracy of the skin sensitivity can be ensured.

In S503, the pixel values of the pixel points in the skin region image in the original image are adjusted according to the skin sensitivity, and the original image after the pixel values are adjusted is used as a sensitivity distribution diagram to display the sensitivity distribution diagram.

In this embodiment, in order to enable the user to intuitively determine the skin sensitivity of each local skin area in the skin area, the electronic device may change the pixel value of each pixel point in the skin area in the original image, so that the distribution of the skin sensitivity is not displayed, and the display effect is improved. Based on this, the electronic device may adjust the pixel value of each pixel point in the skin region according to the skin sensitivity, and use the original image after the pixel value is adjusted as a sensitivity distribution diagram for representing the skin sensitivity distribution condition of the skin region.

In a possible implementation manner, the electronic device may identify other area images except for the skin area image as a background area image, adjust a pixel value of each pixel point in the background area image to a preset value, for example, set all pixel points in the background area image to black, so as to prevent the background of the picture from affecting the display effect of the sensitivity distribution of the skin area. Illustratively, fig. 11 shows a sensitivity distribution diagram provided by an embodiment of the present application. As shown in fig. 11, each pixel point in the background region in the sensitivity distribution diagram is provided with a uniform pixel value so as to highlight the sensitivity distribution of the skin region, and a corresponding comparison table between the sensitivities and the pixel values is configured so that the user can determine the skin sensitivities corresponding to different pixel values.

In a possible implementation manner, the electronic device may crop the skin area image from the original image, adjust a pixel value of each pixel point in the skin area image, and display the skin area image after the pixel value is adjusted as the sensitivity distribution diagram. Illustratively, fig. 12 shows a sensitivity distribution diagram provided by another embodiment of the present application. As shown in fig. 12, the sensitivity distribution diagram only includes skin regions, and does not include background regions, and is configured with a corresponding comparison table between sensitivities and pixel values, so that the user can determine the skin sensitivities corresponding to different pixel values.

Further, as another implementation of the present application, fig. 13 is a flowchart illustrating a specific implementation that, in S503, the pixel values of the pixel points in the skin region in the original image are adjusted according to the skin sensitivity according to the present application. Referring to fig. 13, compared to the embodiment shown in fig. 5, S503 in this embodiment specifically includes S5031 to S5032, which are detailed as follows:

further, the adjusting the pixel value of each pixel point in the skin region in the original image according to the skin sensitivity includes:

in S5031, based on a preset pixel mapping relationship, an adjustment pixel value associated with the skin sensitivity corresponding to each pixel point is determined.

In this embodiment, the electronic device may establish a pixel mapping relationship, where the pixel mapping relationship specifically defines a pixel value corresponding to each skin sensitivity in the sensitivity distribution diagram. The electronic device may query the pixel value associated with each pixel point in the pixel mapping relationship, and use the queried pixel value as the adjusted pixel value.

In a possible implementation manner, the pixel mapping relationship may be specifically a conversion algorithm, and the adjusted pixel value corresponding to the skin sensitivity may be determined by introducing the skin sensitivity of the pixel point into the conversion algorithm.

In a possible implementation manner, the adjusted pixel value may specifically include pixel values corresponding to a plurality of different channels. If the original image is an RGB image, the adjusted pixel values specifically include pixel values of three channels, namely a red channel, a green channel and a blue channel; if the original image is a printing color mode CMYK image, the adjusted pixel values specifically include pixel values of four channels, namely a cyan channel, a magenta channel, a yellow channel and a black channel.

In S5032, the original pixel value of the pixel point in the original image is replaced with the adjusted pixel value.

In this embodiment, the electronic device may use the adjusted pixel values determined by the pixel points in each skin region image to replace the pixel values in the original image, so as to achieve the purpose of adjusting the pixel values in the original image.

In the embodiment of the application, the pixel mapping relation is set, the adjustment pixel value corresponding to each pixel point is inquired, and the pixel value of each pixel point in the original image is set based on the adjustment pixel value, so that the sensitivity distribution schematic diagram is automatically generated, and the generation efficiency is improved.

Further, as another embodiment of the present application, if the obtained original images are sequentially extracted based on the frame numbers based on the video data to be captured, in S503, the generating and displaying the sensitivity distribution diagram may specifically be: and sequentially displaying the sensitivity distribution schematic diagram associated with each original image based on the frame number of each original image.

In this embodiment, the electronic device may sequentially determine the skin sensitivity of each pixel point in the skin region of each original image according to the frame number, and adjust the pixel value of each pixel point in the original image based on the skin sensitivity to generate a sensitivity distribution diagram of the original image. Based on this, the electronic device may also sequentially display the sensitivity distribution diagram corresponding to each original image based on the frame number corresponding to each original image, so as to achieve dynamic display of skin sensitivity and improve the display effect.

It can be seen from the above that, in the method for displaying skin sensitivity provided in the embodiment of the present application, the original image including the shot object is obtained, the skin area image is determined from the original image, the skin sensitivity associated with each pixel point is obtained according to the pixel value of each pixel point in the skin area image, and the pixel value of the corresponding pixel point in the original image is adjusted according to the determined skin sensitivity, so as to generate a sensitivity distribution diagram, so that a user can know the whole skin sensitivity in the sensitivity distribution diagram and can also determine the sensitivity corresponding to each local skin. Compared with the existing skin detection technology, the generated sensitivity distribution schematic diagram is generated by adjusting the pixel values of the pixel points based on the original image, so that the outline of the skin area is consistent with that of the original image, the sensitivity corresponding to each local area can be determined by viewing the sensitivity distribution schematic diagram, and the display effect is improved; on the other hand, the generation process of the sensitivity distribution schematic diagram can be completed only by the electronic equipment comprising the camera module, and a user does not need to go to a specific medical institution to complete the generation process, so that the convenience of skin sensitivity acquisition is greatly improved, the acquisition difficulty is reduced, and the skin detection efficiency is improved.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
