Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The method for displaying the image provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1, a method for displaying an image according to an embodiment of the present application includes:
step 101: and acquiring eye parameters of the user and position parameters of the user relative to the terminal equipment.
In this step, the user eye parameters may represent whether the user's vision is impaired and the condition of the vision impairment, specifically, the user eye parameters include: at least one of a type of refractive error of the user and a refractive power of the user. Among these, the types of ametropia include myopia, astigmatism, hyperopia, presbyopia, and the like. For those users whose vision is not impaired, they can be considered a special type of ametropia. Here, the user may input the eye parameter of the user into the terminal device in advance, and of course, the eye parameter input in advance by the user is not necessarily the type of refractive error and/or the refractive index of the user, and may be any type of refractive error and/or refractive index.
Step 102: target scene information is collected.
In this step, the terminal device is a device with an image acquisition function, for example, may be a mobile phone, a tablet computer, or the like. Here, the image capturing unit for capturing the object scene information by the terminal device may be a camera, but is not limited thereto. Specifically, the terminal device may collect target scene information in a target direction, where the target direction is associated with a pose of the terminal device and a position of the image collecting unit on the terminal device. The terminal equipment is taken as a mobile phone for explanation, the image acquisition unit can be a rear camera on the mobile phone, and the target direction is the direction of the back face of the mobile phone, namely the shooting direction of the rear camera. Here, the user can select the target direction according to the requirement, so that the terminal equipment can collect the scenery information required by the user. As shown in fig. 2, the user only needs to face the rear camera of the mobile phone to the front of the user to view the image information in front of the user, and the scene information in front of the user can be acquired by performing the first input to the terminal device.
Step 103: and determining the display parameters of the target scene information in the terminal equipment based on the eye parameters and the position parameters of the user.
In this step, the display parameter includes a target display size, where the target display size may indicate a display size of the target scene information when displayed on the terminal device display screen. It will be appreciated that the terminal device is provided with a predetermined display size, which is determined by the field of view of the terminal device, and may be displayed entirely on the display screen of the terminal device when a scene within the field of view is to be displayed with the predetermined display size. The target display size may be greater than, less than, or equal to a preset display size of the terminal device. Here, in order to enable different visually impaired users, the imaging of the target scene information on the terminal device can be seen with different distances from the terminal device. And taking the eye parameters of the user and the position parameters of the user relative to the terminal equipment as the basis for calculating the target display size. Preferably, the display parameter further comprises at least one of a target resolution value and a target brightness value. The target resolution value can indicate the resolution of the target scenery information when the target scenery information is displayed on a display screen of the terminal equipment; the target luminance value may indicate a luminance size of the target scene information when displayed on the terminal device display screen.
Step 104: and displaying the target image according to the display parameters.
In this step, the target image is an image corresponding to the target scene information. As can be seen from fig. 2, the scenery in the target scenery information includes an automobile, a house and a tree, and the target image displayed in the display screen of the terminal device includes images of the automobile, the house and the tree, so that the remote scenery is presented on the terminal device. Here, after collecting the target scene information, the terminal device generates an image based on the collected target scene information and the calculated display parameters and displays the image. Here, the target image may be displayed in a picture format or a video format in the terminal device. Preferably, the terminal device collects target scene information once every preset time period, and generates and displays a target image based on the latest collected target scene information and the calculated display parameters, wherein the preset time period is shorter, for example, 10 ms, 100 ms, and the like. Therefore, the terminal equipment can display the target image corresponding to the target scene information in real time.
The display size of part or all of the image contents of the target image is the same as the target display size. That is, the entire image content of the target image can be displayed in the target display size; the partial image content of the target image may be displayed at a target display size, and the display size of the remaining image content may be different from the target display size. Optionally, when the terminal device displays the target image, the target image is displayed based on all the parameters included in the display parameters. For example, when the display parameters include a target display size, a target resolution value, and a target luminance value, the display size at the time of displaying the target image is adjusted to the target display size, the resolution of the display is adjusted to the target resolution value, and the luminance of the display is adjusted to the target luminance value.
In the embodiment of the application, the eye parameters of the user and the position parameters of the user relative to the terminal equipment can be obtained, wherein the eye parameters of the user comprise: at least one of a type of refractive error of the user and a refractive power of the user. Whether the user's vision is impaired or not and the degree of vision impairment in the case of vision impairment are determined based on the user's ocular parameters. Based on the position parameters of the user relative to the terminal equipment, the position relation between the user and the terminal equipment when the user uses the terminal equipment is determined. Target scene information is collected. And acquiring target scene information which the user wants to know through the terminal equipment. And determining display parameters of the target scene information in the terminal equipment based on the eye parameters and the position parameters of the user, wherein the display parameters comprise target display sizes. And taking the vision impaired condition of the user and the position relation between the user and the terminal equipment as the basis for calculating the target display size. And displaying the target image according to the display parameters, wherein the target image is an image corresponding to the target scene information, and the display size of part or all of the image content of the target image is the same as the target display size. The embodiment of the application presents the far scenery in the near terminal equipment through the target image. And determining the display size of the target image based on the eye parameters of the user and the position parameters of the user relative to the terminal equipment, so that the target image is clearly displayed in front of the user in a proper size. Especially for most people with ametropia, the far scene can be seen clearly even without wearing glasses.
Optionally, the location parameter includes a distance of the user relative to the terminal device, step 103 above: based on the eye parameters and the position parameters of the user, determining the display parameters of the target scene information in the terminal device may include:
and calculating to obtain the target display size according to the eye parameters of the user and the distance between the user and the terminal equipment.
It should be noted that in most cases, the further the object is from the user's eye, the less likely the user will see the object. Likewise, the greater the refractive power of the user, the less likely the object will be visible. Of course, different ametropia types have different effects on the user, with some people of ametropia types looking at objects more clearly than others, for example, near vision people with the same refractive power looking at objects at a closer distance (e.g. 30 cm) than far vision people. Therefore, the type of refractive error, the refractive power and the distance between the user's eye and the terminal device all affect whether the user can see the first image content in the target image clearly. Therefore, some or all of the three can be used as a basis for calculating the target display size.
Preferably, the target display size is larger than a preset display size of the terminal device, wherein the preset display size is determined by a field of view of the terminal device, and when a scene in the field of view needs to be displayed by adopting the preset display size, the scene can be displayed in a display screen of the terminal device. That is, for a visually impaired user, displaying the target image at the preset display size does not satisfy the user's need to see the target scene clearly. Therefore, it is necessary to calculate a target display size larger than the preset display size. Here, the target display size may be a target numerical multiple of the preset display size, wherein the target numerical is greater than 1. The target value may be calculated based on the eye parameter of the user and the distance of the user from the terminal device, and then the target value multiple of the preset display size, that is, the target display size, is calculated based on the preset display size. For example, if the target value is 1.1 and the preset display size is a, the target display size is 1.1a.
The process of calculating the target value based on the user's ocular parameters and the user's distance from the terminal device is described in detail below. Specifically, the first target formula may be: ψ=f (α) +k1d, a target value is calculated; in the first target formula, ψ represents a target value, α represents a user eye parameter, f represents a preset mapping function, k1 represents a scaling factor larger than 0, and d represents a distance between a user and a terminal device. In the case where the user's ocular parameters include the type of refractive error and the refractive power, the higher the refractive power, the greater the f (α); if the refractive power is unchanged, the f (alpha) values corresponding to different types of refractive errors are different.
It is to be understood that the process of calculating the target value is not limited to the above manner, and the target value may be calculated according to a preset weight corresponding to each parameter, for example. For example, the weight of the first parameter is preset to be a, the weight of the second parameter includes B1 and B2 … …, and the weight of the third parameter is C. The first parameter is the distance between the eyes of the user and the terminal equipment; the second parameter is the type of refractive error input by the user in advance, the different types of refractive error correspond to B1 and B2 … … respectively, and the third parameter is the refractive index input by the user in advance. When calculating the target value, the target value may be obtained according to a second target formula. A second target formula: m=s×a+b+n×c, where M represents a target value, S represents a distance between the user' S eye and the terminal device, a represents a weight preset for the first parameter, B represents a weight preset for the second parameter, the values of B corresponding to different types of ametropia are also different, N represents a refractive power input in advance by the user, and C represents a weight preset for the third parameter.
In the embodiment of the application, at least one of the distance between the user and the terminal equipment, the type of refractive error and the refractive index is taken as a factor affecting whether the user can see the target image clearly. Based on the method, the target display size with reasonable numerical value can be calculated, and the requirements of different people for seeing the target image clearly are met.
Optionally, the location parameter includes a distance of the user relative to the terminal device, in step 103 above: based on the user eye parameters and the position parameters, determining that the target scene information is before the display parameters of the terminal equipment, the method further comprises:
an eye image of a user is acquired.
In this step, an eye image of the user may be acquired by using a further image acquisition unit in the terminal device. For example, the terminal device is provided with a front camera, through which an eye image of the user is acquired.
And determining a focus area of the user sight on a display screen of the terminal equipment according to the position of the pupil in the eye image.
In this step, the focus area is a focus point of the user in the display screen, and specifically, the focus area may be understood as a preset range centered on a focus position in the display screen of the terminal device. The focal position comprises the intersection point position of the sight line of the user and the display screen when the user views the display screen. It will be appreciated that after the user has been fixed in position relative to the terminal device, the user looks at a different location or region in the display screen and the position of the user's pupil in the eye will change accordingly. Assuming that the user looks at the midpoint of the display, the pupil is located at the midpoint of the eye. When the user looks towards the upper right corner of the display screen, the pupil will be offset towards the upper right corner of the eye; when the user looks towards the lower left corner of the display screen, the pupil will be offset towards the lower left corner of the eye. Based on this, the focal area of the user's line of sight in the display screen may be determined from the position of the pupil in the eye.
Specifically, the eyes and the display screen may be divided into the same number of areas based on the same area division rule, and each area in the eyes corresponds to one area in the display screen, and the positions of the corresponding two areas in the eyes and the display screen are the same, respectively. As shown in fig. 2 and 3, the eyes and display screen may be divided into nine grid forms, each containing nine distinct regions. As shown in fig. 2, when the user's eye 21 is looking at the first region 22 in the display screen, see fig. 3, the pupil 31 is located in the second region 33 of the eye 32. With continued reference to fig. 2, when the user's eye 21 is looking at the third region 23 in the display screen, with continued reference to fig. 3, the pupil 31 is located in the fourth region 34 of the eye 32. Based on this, in the case where it is determined from the eye image of the user that the pupil 31 is located in the fourth region 34 of the eye 32, the focal region is the third region 23 in fig. 2. In the case where it is determined that the pupil 31 is located in the second region 33 of the eye 32, the focal region is the first region 22 in fig. 2. Here, the description is given by taking the example of dividing the eyes and the display screen into nine areas, but the description is not limited to this.
It will be appreciated that the position of the pupil in the eye will vary within a target range during the user's viewing of all positions on the display screen. Here, the target range need only be divided into regions. Specifically, a plurality of eye images of the user during daily use of the terminal device need to be collected in advance, and the target range is determined. The eye images are eye images shot when the user views the positions of the edges of the display screen.
The distance between the user and the terminal device is inversely proportional to the size of the target range. That is, the closer the user is to the terminal device, the larger the target range; the farther the user is from the terminal device, the farther the target range is. Preferably, a plurality of eye images of a user when using the terminal device under different distance values from the terminal device are collected in advance, so that a target range under the different distance values is determined. When determining a focus area of a user's sight on a display screen of a terminal device according to the position of a pupil in an eye image, determining a corresponding target range based on the distance between the user and the terminal device, then dividing the eye image in the target range, further determining the position of the pupil in the target range, and finally determining the focus area of the user's sight on the display screen of the terminal device by using the position of the pupil.
Correspondingly, step 103 above: based on the eye parameters and the position parameters of the user, determining the display parameters of the target scene information in the terminal device may include:
and calculating to obtain the target display size according to the eye parameters of the user and the distance between the user and the terminal equipment.
In this step, the process of calculating the target display size is the same as the process of calculating the target display size in the above embodiment, and will not be described again.
And calculating to obtain the local display size according to the area of the focus area, the area of the display screen and the target display size.
In this step, the target display size is larger than the preset display size of the terminal device, and the local display size is smaller than the preset display size. The preset display size is determined by the field of view of the terminal device, and when the scenery within the field of view is required to be displayed by adopting the preset display size, the scenery can be displayed in the display screen of the terminal device.
Step 104 described above: displaying the target image according to the display parameters may include:
displaying the first image content by adopting a target display size and displaying the second image content by adopting a local display size according to the display parameters;
wherein the first image content includes image content of the target image located in the focus area, the second image content includes image content of the target image other than the first image content, and part or all of the second image content is displayed in the display screen.
It should be noted that by reducing the second image content after the first image content is enlarged, the second image content can be displayed in the display screen as much as possible. As shown in fig. 2 and 4, when the user views the tree in the target image, the display size of the tree in the display area is increased, and the display sizes of houses and vehicles are reduced.
Fig. 5 is a schematic diagram of practical application of an image display method according to an embodiment of the present application, where a terminal device is used as a mobile phone to illustrate the method, including:
step 501: and receiving the target function triggered by the user and the input configuration information. The target function is a function of the method for realizing the image display on the mobile phone, and the configuration information comprises: type of ametropia and refractive power. For example, the user is near-sighted 500 degrees, the configuration information entered is: myopia, 500.
Step 502: and controlling a rear camera of the mobile phone to acquire target scene information in the shooting direction.
Step 503: human eye distance and eye image are detected. The eye distance comprises the distance between the eyes and the front camera of the mobile phone, and the eye image is a human eye image obtained by shooting a human face image by the front camera. And determining a focus area of the user on the mobile phone display screen, namely an area focused by the user, based on the eye image. And determining the target display size and the local display size based on the human eye distance and the configuration information input by the user. The target display size is larger than the preset display size of the terminal equipment, and the local display size is smaller than the preset display size.
Step 504: the display size of the first image content of the target image is adjusted to the target display size, and the display size of the second image content is adjusted to the partial display size. Wherein the first image content comprises image content of the target image that is located within the focal region and the second image content comprises image content of the target image other than the first image content.
Step 505: and displaying the processed target image.
In the embodiment of the application, the focus of attention of the user on the target image is determined based on the eye image when the user views the terminal equipment, and the display size of the scenery of the focus of attention on the target image is adjusted to be the target display size, so that the target image can be scaled more accurately. Further, the display size of the non-focused scenery is adjusted to be the local display size, so that the situation that other image contents are lost due to the fact that the display size of part of image contents in the target image is increased can be avoided.
Optionally, after displaying the first image content with the target display size and displaying the second image content with the partial display size according to the display parameter, the method may further include:
under the condition that the distance value of the focal area from the edge of the target side of the display screen is smaller than a preset threshold value, the shooting angle of a first image acquisition unit on the terminal equipment is adjusted to be deviated to the target side or the image acquisition unit for acquiring image information on the terminal equipment is adjusted to be a second image acquisition unit by the first image acquisition unit, wherein the first image acquisition unit is an image acquisition unit for acquiring target scene information, and the field of view of the second image acquisition unit is larger than that of the first image acquisition unit.
In this step, the preset threshold is smaller, and the specific value thereof can be set according to the user's requirement. The situation that the distance value of the focal region from the edge of the target region is smaller than the preset threshold value can be regarded as that scene information which the user wants to view is not presented in the target image. At this time, the terminal device may be adjusted to increase the scene information contained in the target image, or directly collect the scene information required by the user. The terminal device is taken as a mobile phone for explanation, the first image acquisition unit for acquiring the object scene information can be a common camera or a standard camera, and the angle of view is smaller. The second image acquisition unit can be a wide-angle camera, the field angle of view is larger, and compared with a common camera, a scene with a larger range can be shot. Of course, other situations can be preset, and the situation can be regarded as that the scene information which the user wants to view is not presented in the target image, for example, the situation that the user's sight does not fall to the display screen, namely, when the user views the display screen. In this case, the above-described operation is also performed, i.e., the shooting angle of the first image capturing unit on the terminal device is adjusted or the image capturing unit that captures the image information on the terminal device is adjusted from the first image capturing unit to the second image capturing unit.
For example, when the distance value of the focal area from the upper edge of the mobile phone is smaller than the preset threshold, the shooting angle of the first image acquisition unit is adjusted to be shifted upwards, so that the scene information above the scene information corresponding to the target image can be included in the target image. Fig. 6 is a schematic diagram of a practical application of an embodiment of the present application, including: steps 601 to 607, wherein steps 601 to 603 are the same as steps 501 to 503 in fig. 5, and steps 606 to 607 are the same as steps 504 to 505 in fig. 5, and are not described again. Step 604: it is determined whether the visible area expansion is performed, if yes, step 605 is executed, and if not, step 606 is executed. Here, the visible region is a region photographed by a rear camera. And if the front camera detects that the human eye sight extends beyond the edge range of the mobile phone screen, judging that the user wants to further adjust the visible area range. Step 605: and angle adjustment is performed on the rear camera or the work camera is automatically adjusted and replaced (such as a wide-angle lens is replaced), so that scene information in a larger range is extracted.
In the embodiment of the application, the user can enlarge the visual range without mobile terminal equipment, and more scene information is displayed in the target image.
