Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "at least two" means two or more unless specifically limited otherwise.
The following disclosure provides many different embodiments or examples for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials. In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
The image display method provided by the embodiment of the application can be applied to any terminal with an image display function, such as a tablet computer, a notebook computer, a desktop computer, a television, a smart phone, a touch screen, an independent display and the like. The following detailed description of the embodiments, the apparatus, the terminal and the storage medium, it should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
First, the principle and related knowledge involved in the embodiments of the present application will be explained. For the planar display, taking a scene where the user is at the best viewing position as an example, since the image of the planar display is perpendicular to the line of sight of the user, the distance between the eyes of the user and the center of the image is smaller than the distance between the eyes of the user and other positions of the image, so that the image in the middle of the image is seen by the user to be larger, and the image in the edge of the image is seen to be smaller. For the curved surface display, because the curved surface screen has curvature, the concave part shape is far away from the direction of the user, so that compared with the plane display, the distance between the middle position of the curved surface display picture and the eyes of the user is increased, the distance between the edge position of the curved surface display picture and the eyes of the user is decreased, the size of each part of the image in the whole image displayed by the curved surface is as uniform as possible, and the influence of the factor that the positions of the eyes of the user and the different positions of the picture have different distances is small.
The present invention will be described in detail with reference to the drawings and the detailed description, referring to fig. 1a to 5.
Referring to fig. 1a, fig. 1a is a schematic flow chart of an image display method according to an embodiment of the present disclosure. The embodiment of the application comprises the following steps:
and step 110, acquiring an overall image.
The whole image is an image displayed in the display interface in a complete manner at the terminal. For example, the overall image may be a complete image that the display interface displays without damage, occlusion, or the like. The whole image may include one or more elements. For example, if a user opens two pictures for display on the display interface at the same time, the two pictures may be determined to be a whole image together.
The display interface refers to a page displayed on a terminal display screen. The display interface may be used to display images, text, or buttons/options that may be operated by the current user, etc. The current user can realize corresponding functions by operating the content in the display interface. For example, when the terminal is a tablet computer, the current user may adjust the relevant parameter by clicking an option of the display interface, for example, to change the brightness of the screen.
In some embodiments, the image acquisition module 41 may acquire the whole image through various hardware/software functions of an image sensor of the terminal, an image recognition model, and the like. In some scenarios, for example, when a user uses the terminal to watch a video or play a game, the whole image may be a video image that changes from moment to moment in the display interface, and the image obtaining module 41 may obtain the whole image in units of video frames or time for facilitating subsequent processing of the image. For example, the image sensor may acquire a full image displayed every frame, every two frames, every second in the display interface.
In some embodiments, the image acquisition module 41 may also acquire the whole image from an external terminal. For example, the image obtaining module 41 may obtain the image uploaded to the display interface by the user from another terminal of the user, or may obtain the whole image by reading from a storage space in which the image uploaded by the user is stored, and the obtaining manner of the whole image is not limited in this embodiment.
And 120, dividing a display interface into a plurality of areas, wherein the areas divide the whole image into local images.
The area of the display interface may be a unit surrounded by setting a closed virtual boundary on the display interface. Wherein, the closed virtual boundary can be in any shape, size, position and number. For example, the display interface may be divided into a plurality of rectangular regions, a plurality of circular regions, or a plurality of regions containing arbitrary irregular shapes.
In some embodiments, region partitioning module 42 may partition the entire image into partial images. For example only, if the current display interface is divided into an upper rectangular area and a lower rectangular area, the images respectively located in the two rectangular areas are two local images of the whole image. Since the area division of the display interface is equivalent to the area division of the entire image when the entire image is displayed on the display interface, the area division module 42 may divide the area of the display interface by software/hardware such as an image division unit, an image division model, an image recognition unit, and an image sensor of the terminal.
In some embodiments, the entire image may have display objects displayed therein. The display object refers to an entity displayed in the entire image or a unit included in the entity. For example, the entire image is a landscape image, and the sky, the person, the mountain, the article, and the like displayed in the landscape image are all display objects of the entire image. For example, if the entire image is a face image, the entire face, the five sense organs of the face, and the attachments on the face in the face image are all the display objects of the entire image.
In some embodiments, in response to a change in the outline of the display object, the shape of the region in the display interface may be modified according to the outline of the display object. In some embodiments, the contour change event may include one of a contour area change, a contour shape change, a contour position change, or the like, or any combination thereof. For example, if the current display object is a face image, the contour of the display object may be a face contour, a facial contour, or the like, and if a motion change such as turning a head or nodding a head of a face in the image is detected, the contour area, contour shape, and contour position corresponding to the detected display object are all changed.
In some embodiments, region partitioning module 42 may modify the shape of a region in the display interface according to the outline of the display object. In some embodiments, the modification may include updating the area in which the display object is located. For example, when the region dividing module 42 identifies the contour of the display object that changes, the contour may be directly determined as the region of the display object, for example, the face contour after turning around may be determined as the region of the display object. In some embodiments, the modification may also include adding, deleting, or deleting regions in which the display object is located or contained. For example, the contour of the current five sense organs may be added to the face contour after the head is turned as the area of the display object.
By the method, the change of the outline of the display object is obtained to update the area division in the display interface, so that the continuous processing and the real-time processing of the subsequent images can be realized, and the flexibility and the accuracy of the image processing are improved.
In some embodiments, the region dividing module 42 may divide the display interface into a plurality of regions, each region corresponding to one pixel, based on the pixels of the display interface. For example, if the pixels of the display interface are 1024 × 768, the display page may be divided into 786432 regions corresponding to the pixels, that is, 786432 rectangular regions of equal size.
By the method, the area division speed can be increased, and the local image can be accurately processed to the pixel unit level, so that the processing precision and the processing efficiency of the image are synchronously improved.
And step 130, acquiring the distance between the user and the local image.
In some embodiments, the overall image may have the shape of the display object displayed therein. For example, the display object may be a cup in a cylindrical shape, and then the display object is cylindrical in shape.
In some embodiments, the distance acquisition module 43 may determine the length of a straight line of the user from the geometric center of the shape as the distance of the user from the local image. For example, if the current image is a cup in a cylindrical shape, the length of the straight line between the center point of the cylindrical shape and the user is determined as the distance between the user and the partial image. It should be noted that, in this embodiment, the position of the user is determined by the viewing position of the user, so the distance between the shape and the user may be equal to the distance between the shape and the eyes of the user. By the method, the distance between the local image and the user can be rapidly and accurately determined according to the shape of the display content, so that the local image can be accurately processed according to the distance subsequently.
In some embodiments, the distance acquisition module 43 may determine the length of the straight line between the user and the center point of the region where the local image is located as the distance between the user and the center point. In some scenarios, it is difficult to determine the center of an irregular-shaped display object, a partial image of the display object may be divided into regular-shaped regions, and then the distance between the center point of the regular-shaped region and the straight-line length of the user may be determined as the distance between the center point of the regular-shaped region and the straight-line length of the user, for example, if the region may be a rectangle, the distance between the center of the rectangular region and the straight-line length of the user may be determined as the distance between the center point of the rectangular region and the straight-line length of the user. By the method, under the condition that the shape of the display content is irregular or other conditions that the distance between the local image and the user is difficult to determine exist, the distance between the local image and the user can be still rapidly and accurately determined according to the shape of the display content, so that the local image can be accurately processed according to the distance in the follow-up process.
In some embodiments, the distance acquisition module 43 may also detect a change in distance between the user and the local image. For example, the distance obtaining module 43 may detect the distance change by detecting whether the relative position between the user and the local image changes, for example, the distance obtaining module 43 may detect that the user moves, the display interface is moved, the position of the local image on the display interface changes, and the like. In some embodiments, the scaling parameter of the local image may be determined according to the changed distance, and the description about the scaling parameter may be referred to in step 140.
The distance obtaining module 43 may obtain the distance through various software/hardware having functions of infrared distance measurement, ultrasonic distance measurement, image point location identification, image coordinate processing, and the like, and the obtaining manner of the distance is not limited in this embodiment.
The zoom parameter refers to a value for zooming out or zooming in on the object. The scaling parameter is usually embodied in the form of a ratio, for example, a scaling parameter of 1:4 means that the object is enlarged by 4 times, and a scaling parameter of 2:1 means that the object is reduced by 1/2.
Referring to fig. 1b, fig. 1b is another schematic flow chart of an image display method according to an embodiment of the present disclosure. With reference to fig. 2a and fig. 2b, before step 104, the embodiment of the present application further includes the following steps.
And step 141, acquiring a preset curvature of the display interface.
The preset curvature refers to a preset curvature radius value after the display interface is converted from a plane to a curved surface. For example, the preset curvature R1000 indicates that the curvature radius corresponding to the curved surface is 1000mm, and similarly, the preset curvature R1500 indicates that the curvature radius corresponding to the curved surface is 1500 mm. In some embodiments, the terminal may obtain the preset curvature input or selected by the user, for example, the user may input one or more numerical values as the preset curvature by typing or voice, and for example, the user may select one or more numerical values as the preset curvature by clicking on the display interface. The present embodiment does not limit the manner of obtaining the preset curvature.
And 142, taking the ratio of the preset curvature to the distance as a scaling parameter corresponding to the local image.
Taking fig. 2a as an example, to facilitate understanding of the determination of the scaling parameter in step 142, an abstract curved display interface is simultaneously presented at the current display interface. According to the foregoing description, the curved surface display adjusts the distance from the local image at each position to the user compared to the planar display, so that in order to achieve the curved surface display effect on the planar display interface, the corresponding zoom parameter may be determined for each local image.
Now, it is assumed that the user position is exactly located at the center of the curved display interface, the preset curvature is R, the distance between the first image 21 in the display interface and the user is L, and the distance between the second image 22 in the curved display interface and the user is L'. In order to make the user see the effect of the first image 21 on the display interface, and the effect of the user see the second image 22 in the curved display interface, the projected image of the first image 21 on the curved display interface can be regarded as the second image 22, and correspondingly, the projected image of the second image 22 on the display interface can also be regarded as the first image 21. Optionally, since the curved surface display interface has the preset curvature R, the projection parameters of the two images are related to the preset curvature R, and the projection connecting line of the two images is the connecting line between the first image 21, the second image 22, and the center of the curved surface circle.
As can be seen from fig. 2a and the above description, the ratio between the preset curvature and the distance, i.e. R/L, is the scaling parameter corresponding to the local image, and the description about processing the local image using the scaling parameter can be referred to in step 150.
And 150, processing the local image by using the scaling parameter corresponding to the local image to obtain a processed local image.
In some embodiments, if the distance between the user and the local image is greater than the preset curvature, the image processing module 45 may perform an enlargement process on the local image according to the zoom parameter of the local image.
With reference to fig. 2a, fig. 2a is another schematic diagram of processing a partial image according to an embodiment of the present disclosure. For example only, in some scenarios, the distance between the user and the local image is greater than the preset curvature, for example, the user wants to use a computer to realize a home theater viewing experience of a curved screen television, and the user needs to be far away from the current use position of the computer, which may be the user position when the user uses the computer to work. The predetermined curvature of the computer is not generally large considering the size of the screen of the computer, and the home theater viewing distance is generally more than 3 meters. Therefore, it is reasonably assumed that the preset curvature of the computer is R1000, that is, 1000mm, and the distance from the user to the local image is 3000mm, on the premise that the distance between the user and the local image is not changed, the scaling parameter of the local image is 1:3, that is, the image processing module 45 may perform 1:3, enlarging the local image to realize the display effect of the curved surface display interface in the display interface.
The whole image may include a plurality of local images, and for different local images, on the premise that there is no symmetry relationship, the distances between the different local images and the user are different, so that the scaling parameters corresponding to the local images with different distances from the user are also different. Continuing with the previous example, the scaling parameters for local image A are 1:3, another partial image with a larger distance from the user exists in the display interface, for example, the partial image B with a distance of 3100mm from the user, and the zoom parameter of the partial image B is 1: 3.1, the presentation image processing module 45 may perform 1: 3.1 amplification process. It can be understood that the local image with a larger distance from the user is equivalent to a smaller image area presented in the field of view of the user, and therefore, in the above manner, when the distance between the local image and the user is greater than the preset curvature, the local image with a larger distance from the user is matched with a larger scaling parameter in the display interface for processing, and the image sizes of the local images in the processed display interface can be made to be approximately consistent, so as to achieve an effect of converting the planar display into the curved display.
In some embodiments, if the distance between the user and the local image is smaller than the preset curvature, the image processing module 45 may perform a reduction process on the local image according to the scaling parameter of the local image.
With reference to fig. 2b, fig. 2b is another schematic diagram of processing a partial image according to an embodiment of the present application. For example only, in some scenarios, similar to the scenario in fig. 2a, the distance between the user and the local image may be smaller than the preset curvature, for example, the user wants to use a tv to achieve the visual effect of playing a game on a curved-screen computer, the user needs to be close to the current tv use position, and the current tv use position may be the user's position when watching a video using the tv. The preset curvature of the tv is not generally small considering the screen size of the tv, and the distance between the user and the computer is generally within 1 meter when the computer is used for playing games. Therefore, it is reasonably assumed that the preset curvature of the television is R2000, that is, 2000mm, and the distance from the user to the local image is 800mm, on the premise that the distance between the user and the local image is not changed, the scaling parameter of the local image is 5:2, that is, the image processing module 45 may perform 5:2, so that the partial image can realize the display effect on the curved surface display interface in the display interface.
To further understand the image display method according to the embodiment of the present application, please refer to fig. 4, where fig. 4 is another schematic diagram of processing a partial image according to the embodiment of the present application.

Now, assuming that the user is at the optimal viewing position of the central diffusion area of the display interface, taking the reduction processing on the partial image R in the shape of a rectangle as an example according to the foregoing, since the scaling parameter is a ratio, to ensure the scaling effect, the image processing apparatus may respectively perform the reduction processing on the length and the width of the partial image R, that is, perform the diagonal scaling processing on the partial image R from the horizontal direction and the vertical direction of the two-dimensional image. For example, the length H and the width W of the partial image R may be synchronously reduced to values equal to the length H 'and the width W' of the partial image Rl, so that the image sizes of the partial images in the whole image of the current display interface are approximately consistent, and the curved surface display effect is achieved.
It should be noted that, in order to optimize the visual effect of the user, the image processing module 45 may process only a part of the partial images in the plurality of partial images. For example, the image processing module 45 may be a machine learning model related to image processing, and may include Deep Neural Network (DNN), multi-layer Perceptron (MLP), Convolutional Neural Network (CNN), and Generative Adaptive Network (GAN), for example. Because the machine learning model has strong computing power and data processing power, the image processing module 45 can identify which local images are only required to be processed to realize a better curved surface viewing effect for the user, so that the image processing efficiency and the image processing quality can be improved.
And 160, displaying the processed local image on the display interface. In some embodiments, the image display module 46 may display the processed partial image on the display interface through a display unit inside the terminal, or various software/hardware having an imaging function.
Therefore, according to the embodiment of the application, the local images in the display interface can be processed according to the corresponding scaling parameters, so that the sizes of the local images in the display interface are approximately consistent, the effect of curved surface display on the whole image displayed in a plane can be realized, and the experience of a user is improved.
