It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following describes in detail the method for displaying an image according to the embodiments of the present application 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 the eye parameters of the user and the position parameters of the user relative to the terminal equipment.
In this step, the user eye parameters may represent whether the user has impaired vision and the condition of impaired vision, and specifically, the user eye parameters include: at least one of a type of ametropia of the user and a diopter number of the user. The ametropia types include myopia, astigmatism, hyperopia, presbyopia and the like. For those users who have no impaired vision, it can be considered a particular type of ametropia. Here, the user may input his or her own ocular parameters into the terminal device in advance, and of course, the ocular parameters input by the user in advance are not necessarily the user's own refractive error type and/or refractive power, and may be any refractive error type and/or refractive power.
Step 102: and collecting target scene information.
In this step, the terminal device is a device with an image capturing function, such as a mobile phone and a tablet computer. Here, the image acquisition unit of the terminal device acquiring the target scene information may be a camera, but is not limited thereto. Specifically, the terminal device may acquire target scene information in a target direction, wherein the target direction is associated with the attitude of the terminal device and the position of the image acquisition unit on the terminal device. The terminal device 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 towards the back 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 device collects the scene information required by the user. As shown in FIG. 2, the user wants to view the image information in front of himself, and only needs to orient the rear camera of the mobile phone to the front of himself, and the scene information in front of himself can be collected by inputting the first input to the terminal device.
Step 103: and determining display parameters of the target scene information on the terminal equipment based on the user eye parameters and the position parameters.
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 display screen of the terminal device. It can be understood that the terminal device is provided with a preset display size, the preset display size is determined by the field of view of the terminal device, and when the scenes in the field of view are required to be displayed in the preset display size, all the scenes can be displayed in the display screen of the terminal device. The target display size may be larger than, smaller than, or equal to a preset display size of the terminal device. Here, in order to allow different visually impaired users to see the imaging of the target scene information on the terminal device clearly at 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 a basis for calculating the target display size. Preferably, the display parameters further include at least one of a target resolution value and a target brightness value. The target resolution value can indicate the resolution of target scene information when the target scene information is displayed on a display screen of the terminal equipment; the target brightness value may indicate a brightness level of the target scene information when displayed on the display screen of the terminal device.
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 a car, a house and a tree, and the target image displayed on the display screen of the terminal device includes respective images of the car, the house and the tree, so that the distant scenery is displayed on the terminal device. Here, the terminal device generates and displays an image based on the acquired target scene information and the calculated display parameters after acquiring the target scene information. 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 length, and generates and displays a target image based on the newly collected target scene information and the calculated display parameters, where the preset time length is short, and may be, for example, 10 milliseconds, 100 milliseconds, 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 a part of the image content or the entire image content of the target image is the same as the target display size. That is, the entire image content of the target image may be displayed at the target display size; a portion of the image content of the target image may be displayed at a target display size, with the display size of the remaining image content being 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 parameter includes a target display size, a target resolution value, and a target brightness value, the display size when the target image is displayed is adjusted to the target display size, the display resolution is adjusted to the target resolution value, and the display brightness is adjusted to the target brightness value.
In the embodiment of the application, the user eye parameters and the position parameters of the user relative to the terminal device can be obtained, wherein the user eye parameters include: at least one of a type of ametropia of the user and a diopter number of the user. Determining whether the user's vision is impaired and, in the case of impaired vision, the extent to which the vision is impaired, based on the user's ocular parameters. And determining the position relation between the user and the terminal equipment when the user uses the terminal equipment based on the position parameters of the user relative to the terminal equipment. And collecting target scene information. And acquiring target scene information which a user wants to know through the terminal equipment. And determining display parameters of the target scene information on the terminal equipment based on the user eye parameters and the position parameters, wherein the display parameters comprise a target display size. And taking the vision damage condition of the user and the position relation between the user and the terminal equipment as a basis for calculating the target display size. And further displaying a 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 partial image content or all image content of the target image is the same as the target display size. The embodiment of the application presents the distant scene 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 if the glasses are not worn.
Optionally, the location parameter includes a distance of the user relative to the terminal device, and step 103: determining display parameters of the target scene information on the terminal device based on the user eye parameters and the position parameters, which 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 farther an object is from the user's eyes, the less easily the user can see the object. Likewise, the greater the user's diopter, the less readily it is possible to see the object. Of course different refractive error types have different effects on the user, with some people of refractive error types seeing objects more clearly than others, for example near sighted people with the same refractive power see more clearly than far sighted people when viewing objects at a closer distance (e.g. 30 cm). Therefore, the type of ametropia, the amount of refraction, 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, part or all of the three can be used as the basis for calculating the target display size.
Preferably, the target display size is larger than a preset display size of the terminal device, where the preset display size is determined by a field of view of the terminal device, and when the scenes in the field of view are required to be displayed with the preset display size, all the scenes can be displayed on the display screen of the terminal device. That is, for a user with impaired vision, displaying the target image in the preset display size does not satisfy the user's need to see the target scene clearly. Therefore, a target display size larger than the preset display size needs to be calculated. Here, the target display size may be a target number times the preset display size, where the target number is greater than 1. The target value can be calculated based on the eye parameters of the user and the distance between the user and the terminal device, and then the target value times of the preset display size, namely the target display size, can be 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 1.1 a.
The process of calculating the target value based on the user's eye parameters and the distance of the user from the terminal device is described in detail below. Specifically, the first target formula can be used: psi ═ f (α) + k1d, calculated to give the target value; in the first objective formula, Ψ represents an objective value, α represents an eye parameter of the user, f represents a preset mapping function, k1 represents a scaling factor greater than 0, and d represents a distance of the user from the terminal device. In the case where the ocular parameters of the user include the type of refractive error and the refractive power, the higher the refractive power, the larger f (α) if the refractive type is unchanged; if the refractive power is not changed, the f (alpha) values corresponding to different refractive error types are different.
It is to be understood that the process of calculating the target value is not limited to the above-mentioned 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 set to a, the weight of the second parameter includes B1 and B2 … …, and the weight of the third parameter is set to C. The first parameter is the distance between the eyes of the user and the terminal equipment; the second parameter is the type of ametropia input by the user in advance, different ametropia types correspond to B1 and B2 … … respectively, and the third parameter is the diopter number input by the user in advance. In calculating the target value, the target value may be obtained according to a second target formula. The second target formula: m is sxa + B + nxc, where M denotes a target value, S denotes a distance between the user' S eye and the terminal device, a denotes a weight set in advance for the first parameter, B denotes a weight set for the second parameter, and the values of B are different for different ametropia types, N denotes an ametropia number input in advance by the user, and C denotes a weight set in advance for the third parameter.
In the embodiment of the application, at least one of the distance between the user and the terminal device, the ametropia type and the diopter number is used as a factor for influencing whether the user can see the target image clearly. Based on the method, the target display size with a reasonable numerical value can be obtained through calculation, and the requirement that different people can see the target image clearly is met.
Optionally, the location parameter includes a distance of the user relative to the terminal device, in step 103: determining the target scene information to be in front of the display parameters of the terminal equipment based on the user eye parameters and the position parameters, wherein the method further comprises the following steps:
an eye image of a user is acquired.
In this step, the eye image of the user may be acquired by using another image acquisition unit in the terminal device. For example, the terminal device is provided with a front camera, and an eye image of the user is acquired through the front camera.
And determining a focus area of the sight of the user 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 an intersection point position of the sight of the user and the display screen when the user watches the display screen. It will be appreciated that when the user is fixed in position relative to the terminal device and looks at a different location or area in the display, the location of the user's pupil in the eye will change accordingly. Assume that the pupil is at the very center of the eye when the user looks at the very center of the display screen. When the user looks at the top right corner of the display screen, the pupil will shift towards the top right corner of the eye; when the user looks at the lower left corner of the display screen, the pupil will shift towards the lower left corner of the eye. Based on this, the focus area of the user's sight line in the display screen can be determined according to the position of the pupil in the eye.
Specifically, the eyes and the display screen may be divided into the same number of regions based on the same region division rule, and each region in the eyes corresponds to one region in the display screen, and the positions of the two corresponding regions in the eyes and the display screen are the same. As shown in fig. 2 and 3, the eyes and display screen may be divided into a form of a squared figure, each containing nine different regions. As shown in fig. 2, when the user's eye 21 is looking at the first area 22 in the display screen, see fig. 3, the pupil 31 is located in the second area 33 of the eye 32. With continued reference to fig. 2, as the user's eye 21 gazes at the third area 23 in the display screen, with continued reference to fig. 3, the pupil 31 is located at the fourth area 34 of the eye 32. Based on this, when it is determined that the pupil 31 is located in the fourth region 34 of the eye 32 from the eye image of the user, 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 focus area is the first region 22 in fig. 2. Here, the description will be given by taking an example of dividing the eyes and the display screen into nine areas, but the division of the eyes and the display screen is not limited thereto.
It will be appreciated that the position of the pupil in the eye varies within a target range during the user's viewing of all positions on the display screen. Here, it is only necessary to divide the target range into regions. Specifically, a plurality of eye images of the user during daily use of the terminal device need to be collected in advance to determine the target range. The plurality of eye images are eye images shot when a user views each edge position of the display screen.
The distance between the user and the terminal equipment 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 is; the farther the user is from the terminal device, the farther the above target range is. Preferably, a plurality of eye images of the user when using the terminal device at different distance values from the terminal device are collected in advance, so that target ranges at different distance values are determined. When the focus area of the user sight on the display screen of the terminal device is determined according to the position of the pupil in the eye image, a corresponding target range is determined based on the distance of the user relative to the terminal device, then the eye image is subjected to region division in the target range, the position of the pupil in the target range is further determined, and finally the focus area of the user sight on the display screen of the terminal device is determined by the position of the pupil.
Accordingly, the step 103: determining display parameters of the target scene information on the terminal device based on the user eye parameters and the position parameters, which 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 is not described herein 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 scenes in the field of view are required to be displayed in the preset display size, all the scenes can be displayed in the display screen of the terminal device.
The above step 104: 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;
the first image content comprises image content of the target image located in the focus area, the second image content comprises image content of the target image except the first image content, and part or all of the second image content is displayed in the display screen.
It should be noted that after increasing the first image content, by reducing the second image content, the second image content can be made to 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 size of the house and the car is decreased.
Fig. 5 is a schematic diagram of an actual application of the image display method provided in the embodiment of the present application, and the description is performed by using a terminal device as a mobile phone, where the schematic diagram includes:
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 the following steps: the type of refractive error and the refractive power. For example, if the user is at 500 degrees myopia, the configuration information is entered as: myopia, 500.
Step 502: and controlling a rear camera of the mobile phone to acquire target scene information in the shooting direction.
Step 503: the eye distance and the 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 the eye image obtained by shooting the face image by the front camera. And determining a focus area of the user on the display screen of the mobile phone based on the eye image, namely the area concerned by the user. And determining a target display size and a local display size based on the distance between the human eyes 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 a target display size, and the display size of the second image content is adjusted to a partial display size. Wherein the first image content comprises image content of the target image within the focus area 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 device, and the display size of the focus of attention scenery on the target image is adjusted to the target display size, so that the target image can be zoomed more accurately. Further, the display size of the scenery which is not focused on 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 partial image contents in the target image is increased can be avoided.
Optionally, after displaying the first image content with the target display size and the second image content with the local display size according to the display parameter, the method may further include:
under the condition that the distance value between the focal region and 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 an image acquisition unit for acquiring image information on the terminal equipment is adjusted to be a second image acquisition unit from the first image acquisition unit, wherein the first image acquisition unit is an image acquisition unit for acquiring target scene information, and the view field of the second image acquisition unit is larger than that of the first image acquisition unit.
In this step, the preset threshold is small, and the specific value can be set according to the user requirement. The condition that the distance value from the focal region to the edge of the target region is smaller than the preset threshold value can be regarded as that the 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 included in the target image, or directly acquire the scene information required by the user. The terminal equipment is used as a mobile phone for explanation, and the first image acquisition unit for acquiring the target scene information can be a common camera or a standard camera, and the field angle of the first image acquisition unit is smaller. The second image acquisition unit can be a wide-angle camera, the field angle of the second image acquisition unit is large, and compared with a common camera, a wider-range scene can be shot. Of course, other situations may also be preset, and it is considered that the scene information that the user wants to view is not presented in the target image, for example, the situation that the user does not have his line of sight on the display screen, that is, when the user views outside the display screen. In this case, the above operation is also performed, that is, the shooting angle of the first image capturing unit on the terminal device is adjusted or the image capturing unit capturing 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 from the focal region to the upper edge of the mobile phone is smaller than the preset threshold, the shooting angle of the first image capturing unit is adjusted to shift upward, so that the scene information above the scene information corresponding to the target image can be included in the target image. As shown in fig. 6, a schematic diagram of an actual application of the embodiment of the present application includes: step 601 to step 607, wherein step 601 to step 603 are the same as step 501 to step 503 in fig. 5, and step 606 to step 607 are the same as step 504 to step 505 in fig. 5, and are not repeated here. Step 604: and judging whether the visible area is expanded, if so, executing step 605, and otherwise, executing step 606. Here, the visible region is a region photographed by the rear camera. And when the front camera detects that the sight of the human eyes extends out of the edge range of the mobile phone screen, judging that the user wants to further adjust the range of the visible area. Step 605: and (3) carrying out angle adjustment on the rear camera or automatically adjusting and replacing the working camera (for example, replacing the working camera with a wide-angle lens), and extracting scene information in a wider range.
In the embodiment of the application, the user can increase the visual range without moving the terminal equipment, and more scene information is displayed in the target image.
