Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The terminal screen includes a display screen on a terminal such as a smart phone, a tablet computer, an intelligent wearable device, or any other suitable terminal screen, which is not limited in this embodiment of the present invention.
When a user watches images displayed on a terminal screen, the user can usually select a horizontal screen display mode or a vertical screen display mode, so that the problem of insufficient watching effect is caused. In order to solve the problem, the embodiments of the present invention provide the following technical solutions.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of an image display method according to the present invention is shown, which may specifically include the following steps:
The terminal screen can rotate at any angle in a three-dimensional space, and when the terminal screen rotates, the terminal screen changes in posture relative to the original posture. The posture change data is used for representing a posture change condition, and includes data such as a direction and a degree of posture change, and may specifically include any applicable posture change data, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, the implementation manner of detecting the posture change condition of the terminal screen and obtaining the posture change data may include multiple manners, for example, a gyroscope sensor, an acceleration sensor, a gravity sensor, and the like, which are configured on the terminal, are used to determine the posture of the terminal, and according to the detection result of the one or more sensors, the posture change data of the terminal screen may be obtained, and specifically, any suitable manner may be adopted to detect the posture change data, which is not limited in this embodiment of the present invention.
For example, a user holds a mobile phone and watches a video being played on a screen of the mobile phone, the mobile phone is usually provided with a sensor capable of detecting a posture change condition of the mobile phone, such as a gyroscope sensor, an acceleration sensor, a gravity sensor and the like, and when the user rotates the mobile phone, the sensor can obtain posture change data.
And 102, determining rotation data of the terminal screen rotating around an axis vertical to the terminal screen according to the attitude change data.
In the embodiment of the invention, a user can rotate the terminal screen at any angle, some rotations include rotation of the terminal screen around an axis perpendicular to the terminal screen, and some rotations do not include rotation of the terminal screen around an axis perpendicular to the terminal screen. The rotation data includes data related to the rotation of the terminal screen around an axis perpendicular to the terminal screen, such as a direction of the rotation, an angle of the rotation, a speed of the rotation, and the like, or any other suitable data, which is not limited in this embodiment of the present invention. The rotation data may be in the form of angles, vectors, etc., or any other suitable form. For example, the angle change data is used to characterize the angle of rotation of the terminal screen about an axis perpendicular to the terminal screen, and includes the direction of rotation, e.g., the angle is a positive number representing clockwise rotation, and the angle is a negative number representing counterclockwise rotation.
In the embodiment of the present invention, the implementation manner of determining the rotation data of the terminal screen around the axis perpendicular to the terminal screen according to the posture change data may include various manners, for example, firstly converting the posture change data into coordinate transformation data in a three-dimensional coordinate system, and then calculating data changing around the axis perpendicular to the terminal screen in the coordinate transformation data to obtain coordinate transformation data around the axis perpendicular to the terminal screen as the rotation data; or calculating rotation data of the terminal screen around an axis perpendicular to the terminal screen according to the coordinate transformation data, or any other suitable implementation manner, which is not limited in this embodiment of the present invention.
The coordinate transformation data includes, but is not limited to, data describing coordinate transformation of the object in a three-dimensional space in the form of a rotation matrix, a quaternion, and the like. The rotation matrix is a matrix which has the effect of changing the direction of the vector but not changing the size when the vector is multiplied by the rotation matrix and keeps the chirality, and the posture change data recalled back by the sensor is converted into the rotation matrix. Quaternions are a representation of rotations, complex numbers consisting of real numbers plus imaginary units i, where i ^2 ^ -1. Similarly, quaternions are all made up of real numbers plus three imaginary units i, j, k, and they have the following relationship: i ^2 ^ j ^2 ^ k ^2 ^ 1, i ^0 ^ j ^0 ^ k ^0 ^ 1, each quaternion is a linear combination of 1, i, j and k, i.e. quaternions can be generally expressed as a + bi + cj + dk, where a, b, c and d are real numbers.
According to the coordinate transformation data, rotation data of the terminal screen around an axis perpendicular to the terminal screen can be calculated, and the obtained rotation data can be in the forms of angles, vectors and the like. For example, the angle change of the mobile phone from the position 1 to the position 2 can be calculated according to the rotation matrix, and the scheme does not need the angle change in all directions and only needs to calculate the angle a rotated around an axis vertical to the screen of the mobile phone.
For example, one or more of a gyroscope sensor, an acceleration sensor, a gravity sensor, etc. cannot directly use the detected attitude change data, and the attitude change data is converted into a rotation matrix, i.e., coordinate transformation data describing an object in a three-dimensional space, and then angle change data around a position perpendicular to a terminal screen is calculated according to the rotation matrix.
103, generating an image adjustment strategy of the target image according to the rotation data; the image adjusting strategy comprises the steps of enabling the target image to be adjusted to a target angle in a reverse direction of the rotation direction of the terminal screen; the target image is an image to be displayed.
In the embodiment of the present invention, the target image is an image to be displayed, and includes various forms such as videos, animations, pictures, and the like, or any other suitable forms. Before the target image is displayed, an image adjustment strategy of the target image is generated according to the rotation data. The image adjustment strategy comprises the following steps: and adjusting the target image to a target angle in a direction opposite to the rotation direction of the terminal screen, so that the target image can rotate reversely along with the rotation of the terminal screen.
The target angle may be determined according to the rotation data, and may specifically include a plurality of determination manners, for example, the rotation data includes angle change data, the target angle may be equal to the angle change data or different from the angle change data by a set angle, or any other suitable determination manner, which is not limited in this embodiment of the present invention.
For example, a user watches a video in a vertical screen display mode at the beginning, then the user rotates the mobile phone, one component of the rotation is that the mobile phone rotates clockwise by 45 degrees around an axis vertical to a screen of the mobile phone, in the rotation process from 0 degree to 45 degrees, a gyroscope sensor and an acceleration sensor on the mobile phone continuously detect attitude change data at a set frequency and store the attitude change data in a cache, when the video displays an image of each video frame, the attitude change data is extracted from the cache, the rotation data of a terminal screen around the axis vertical to the screen of the mobile phone is determined, an image adjustment strategy of a target image is generated according to the rotation data, when the mobile phone rotates clockwise by 1 degree, the generated image adjustment strategy is that the image of the video frame rotates anticlockwise by 1 degree on the screen of the mobile phone, when the mobile phone rotates clockwise by 2 degrees, the generated image adjustment strategy is that the image of the video frame rotates anticlockwise by 2 degrees on the screen of the mobile phone, when the mobile phone rotates clockwise by 45 degrees, the generated image adjustment strategy is to make the image of the video frame rotate counterclockwise by 45 degrees on the screen of the mobile phone.
And 104, executing the image adjusting strategy, and displaying the target image in the terminal screen.
In the embodiment of the invention, after the image adjustment strategy is generated, the image adjustment strategy is executed aiming at the target image, and the target image is displayed in the terminal screen. In specific implementation, when the target image is rendered, an image adjustment strategy is executed, when the target image is rendered, the target image is adjusted to a target angle in a direction opposite to the rotation direction of the terminal screen, and then the rendered target image is displayed in the terminal screen.
For example, when a video is played on a terminal screen, an image of each video frame is rendered according to angle change data and then displayed, so that the video is played and reversely rotated along with the rotation of the terminal screen, when the angle of the reverse rotation of the video on the terminal screen is equal to the angle of the rotation of the terminal screen, the video is just not rotated relative to a user watching the video, and a richer watching effect is realized.
In summary, according to the embodiment of the present invention, posture change data is obtained by detecting a posture change condition of a terminal screen, rotation data of the terminal screen rotating around an axis perpendicular to the terminal screen is determined according to the posture change data, and an image adjustment policy of a target image is generated according to the rotation data; the image adjusting strategy comprises the steps of enabling the target image to be adjusted to a target angle in a reverse direction of the rotation direction of the terminal screen; the target image is an image to be displayed, the image adjustment strategy is executed, the target image is displayed in the terminal screen, the target image is made to rotate in the direction opposite to the rotation direction of the terminal screen, the target image is displayed on the terminal screen at any angle, the defect of viewing caused by only horizontal screen display and vertical screen display is overcome, the image rotates reversely along with the rotation of the terminal screen, and therefore the angle of the image is always kept or close to the viewing angle of a user, and more comfortable impression is brought.
Referring to fig. 2, a flowchart illustrating steps of another embodiment of an image display method according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the present invention, the attitude sensor is used to determine the attitude of the terminal, and includes a gyroscope sensor, an acceleration sensor, a gravity sensor, or any other suitable sensor, which is not limited in this embodiment of the present invention. Among them, the gyro Sensor (gyro Sensor) is a simple and easy-to-use positioning and control system based on free space movement and gestures. An acceleration sensor (acceleration transducer) is a sensor capable of measuring acceleration. The gravity sensor adopts an elastic sensitive element to manufacture a cantilever type displacer and an energy storage spring manufactured by the elastic sensitive element to drive an electric contact, so that the conversion from the gravity change to an electric signal is completed. The gyroscope sensor can detect angular velocity, the acceleration sensor can detect acceleration, the gravity sensor can detect acceleration caused by gravity, and detection results of the one or more sensors are obtained respectively.
In the embodiment of the invention, the attitude change data is determined according to the detection result of one or more sensors. For example, the three-dimensional space may be represented by a three-dimensional space coordinate system, the detection result of the gyro sensor is an angular velocity rotating around three coordinate axes, the detection result of the acceleration sensor is a linear acceleration along three coordinate axes, and the detection results of the gyro sensor and the acceleration sensor are combined to obtain the attitude change data.
In the embodiment of the present invention, the specific implementation manner of this step may refer to the description in the foregoing embodiment, and details are not described herein.
And 204, determining the target angle according to the angle change data.
In the embodiment of the invention, the rotation data comprises angle change data, and the image adjustment strategy is generated according to the rotation data, wherein the target angle is determined according to the angle change data. The angle change data and the target angle may be equal in size, or there may be a difference between the size of the angle change data and the size of the target angle, but the difference between the angle change data and the target angle should be within a preset range. For example, the angle change data is 5 degrees and the target angle is 6 degrees. Any suitable preset range may be specifically included, and the embodiment of the present invention is not limited thereto.
In the embodiment of the present invention, in order to improve the viewing effect, the image adjustment strategy further includes enlarging or reducing the target image to the target screen display scale. According to the rotation data, an implementation mode of an image adjustment strategy for generating a target image comprises the steps of determining a target image display proportion according to the rotation data, and therefore when a terminal screen rotates to different angles, amplifying or reducing the displayed target image to different degrees to achieve the target image display proportion. The vertical version video is not displayed in a vertical screen mode, or the horizontal version video is not displayed in a horizontal screen mode, so that partial images cannot be displayed in a terminal screen, and partial areas in the terminal screen are free of images; when the partial images cannot be displayed in the terminal screen, the display scale of the target image is reduced, the viewing experience can be considered, and the integrity of the image information can be ensured.
The target picture display scale is used for determining the size of the displayed target image, the smaller the target picture display scale is, the smaller the size of the target image is, and the larger the target picture display scale is, the larger the size of the target image is. For example, when a user watches a portrait video, in the process of rotating from the terminal screen in the portrait display state to the landscape display state, the target image is gradually enlarged to the target image display scale along with the rotation process. The implementation manner of determining the display ratio of the target picture according to the rotation data may include multiple implementations, for example, determining the display ratio of the target picture to be 105% according to the angle change data being 5 degrees, or any other applicable implementation manner, which is not limited by the embodiment of the present invention.
In this embodiment of the present invention, optionally, one implementation manner of determining the display scale of the target screen according to the rotation data may include: detecting the current angle of the terminal screen according to the rotation data; and the current angle is the angle of the terminal screen around an axis perpendicular to the terminal screen relative to the initial angle, and the target picture display proportion is determined according to the current angle.
When the posture change condition of the terminal screen is detected, the terminal screen can be in any initial posture, for example, when a user watches the terminal screen in a sitting posture or a standing posture, the terminal screen plays a video in a vertical screen display mode or a horizontal screen display mode, and when the detection is started, the long edge of the terminal screen is parallel or approximately parallel to a horizontal plane; or when the user watches the terminal screen in a lying posture, the terminal screen plays a video in a vertical screen display or horizontal screen display mode, and when the detection is started, the long edge of the terminal screen is vertical or nearly vertical to the horizontal plane; or when the detection is started, an included angle with any size is formed between the long edge of the terminal screen and the horizontal plane.
Attitude change data is obtained by continuously detecting the attitude change condition of the terminal screen, and the rotation data is updated accordingly. The current angle of the terminal screen refers to the angle of the terminal screen around an axis perpendicular to the terminal screen relative to the initial angle, and the current angle of the terminal screen can be detected according to the rotation data determined once or for multiple times.
For example, when a user views a video in a landscape display state, initially defining an initial angle of a terminal screen as 0 degree, and as the posture of the terminal screen changes, the first determined rotation data is that the terminal screen rotates clockwise by 10 degrees around an axis perpendicular to the terminal screen, so that a current angle of the terminal screen is 10 degrees, the second determined rotation data is that the terminal screen rotates clockwise by 20 degrees around an axis perpendicular to the terminal screen, so that the first determined angle is superimposed, the current angle of the terminal screen is 30 degrees, the third determined rotation data is that the terminal screen rotates counterclockwise by 10 degrees around an axis perpendicular to the terminal screen, so that the angles determined in the first two times are superimposed, as shown in the schematic diagram of the current angle of the terminal screen shown in fig. 3, and the current angle of the terminal screen is 20 degrees. Specifically, any other suitable manner may be adopted to determine the current angle, which is not limited in this embodiment of the present invention.
And along with the change of the current angle of the terminal screen, the display scale of the target picture is changed. For example, if the current angle of the terminal screen is 5 degrees, the target screen display ratio is 105%, and if the current angle of the terminal screen is 10 degrees, the target screen display ratio is 110%. By determining the target picture display proportion according to the current angle, the most appropriate target picture display proportion is convenient to determine, for example, the target image can fill the display area on the terminal screen, that is, the display area does not have black edges, so that the watching effect is better. Of course, after the target image is enlarged, part of the content will not be displayed in the display area.
One way to determine the display scale of the target picture may be calculated according to a display scale adjustment policy and the current angle, where the display scale adjustment policy is used to determine a relationship between the current angle and the display scale of the target picture, for example, when the current angle is 1 degree, the display scale of the target picture is increased by 1% relative to the original scale, and when the current angle is 2 degrees, the display scale of the target picture is increased by 2% relative to the original scale.
The display scale adjustment strategy can be changed along with the change of the angle range of the current angle of the terminal screen, a plurality of angle ranges need to be divided, and each angle range has a corresponding display scale adjustment strategy. And in response to detecting that the current angle range in which the current angle is located is different from the angle range in which the current angle is located last time, determining a display scale adjustment strategy corresponding to the current angle range. And calculating the display scale of the target picture according to the determined display scale adjustment strategy and the current angle.
For example, when a video displayed in a landscape mode is watched initially, the first angle range is 0-90 degrees, the corresponding display scale adjustment strategy is that the target picture display scale is correspondingly increased along with the increase of the current angle, and the target picture display scale is correspondingly reduced along with the reduction of the current angle; the second angle range is 90-180 degrees, the corresponding display scale adjustment strategy is that the target picture display scale is correspondingly reduced along with the increase of the current angle, and the target picture display scale is correspondingly increased along with the reduction of the current angle; the third angle range is 180-270 degrees, the corresponding display scale adjustment strategy is that the display scale of the target picture is correspondingly increased along with the increase of the current angle, and the display scale of the target picture is correspondingly reduced along with the reduction of the current angle; the range of the fourth angle is 270 degrees to 360 degrees, the corresponding display scale adjustment strategy is that the display scale of the target picture is correspondingly reduced along with the increase of the current angle, and the display scale of the target picture is correspondingly increased along with the reduction of the current angle. The angle range may be divided according to actual requirements, and a corresponding display scale adjustment strategy may be set, which is not limited in the embodiments of the present invention.
And step 206, executing the image adjusting strategy, and displaying the target image in the terminal screen.
In the embodiment of the present invention, the specific implementation manner of this step may refer to the description in the foregoing embodiment, and details are not described herein.
To sum up, according to the embodiments of the present invention, by obtaining the detection result of the attitude sensor, determining the attitude change data according to the detection result, determining the rotation data of the terminal screen rotating around the axis perpendicular to the terminal screen according to the attitude change data, determining the target angle according to the angle change data, determining the target picture display ratio according to the rotation data, executing the image adjustment policy, displaying the target image in the terminal screen, and rotating the target image in a direction opposite to the rotation direction of the terminal screen, the target image is displayed at any angle on the terminal screen, the viewing defect caused by only landscape display and portrait display is overcome, and the image rotates reversely with the rotation of the terminal screen, so that the angle of the image is always kept or close to the viewing angle of the user, thereby bringing more comfortable appearance.
