Fig. 1 is a flowchart of an image display method according to an embodiment of the present application, the method including the following steps S11-S13:
in step S11, in the case where the rotation of the device is detected, the current parameters of the device are acquired;
in step S12, a control instruction for the target image displayed in the device screen is generated according to the current parameters of the device;
in step S13, according to the control instruction, the control target image is subjected to relative rotation in the opposite direction to the apparatus rotation direction, wherein the speed at which the target image is rotated is kept in agreement with the speed at which the apparatus is rotated.
In the embodiment, the current parameters of the equipment are obtained under the condition that the rotation of the equipment is detected; in this embodiment, the device may refer to a device with a screen in a rotating state, for example, a product that is applied to a rotatable screen in a scene such as a conference display device and a shopping guide shown in fig. 2 or fig. 3.
Of course, the device may also refer to a mobile terminal device held by a user, for example, when the user watches contents such as videos and photos through a device such as a mobile phone and a tablet computer, the user may adjust the posture to cause the device to rotate, at this time, when the device is detected to rotate, a current parameter of the device is obtained, where the current parameter may refer to a rotation speed of the device, a rotation direction of the device, and the like, and a control instruction for a target image displayed in a screen of the device is generated according to the current parameter of the device; and according to the control instruction, controlling the target image to perform relative rotation opposite to the rotation direction of the equipment, so that when the equipment rotates to each angle, the target image at each angle is obtained according to the control instruction, and the target image obtained according to the control instruction is displayed on a screen of the equipment. Wherein the speed of rotation of the target image is maintained in line with the speed of rotation of the device.
In general, during the rotation of the device, the image displayed on the device rotates along with the rotation of the device, which may cause the image to be inclined, and the viewing experience of the user is not good. In this embodiment, in order to overcome the above-mentioned defects, in the rotation process of the device, the target image displayed in the device rotates at the same rotation speed and in the opposite direction to the device, so that the picture in the device remains still with respect to some other reference objects (e.g., a horizontal plane, a user who is still) except the device, thereby overcoming the situation of picture inclination occurring in the rotation process of the existing device, and improving the viewing experience of the user.
Under the condition of overcoming the problem of picture inclination, different modes of processing are selected to be carried out on the target image displayed in the equipment, so that different effects can be realized, and the following specific steps are carried out:
in the first method, the target image is not zoomed, and as shown in fig. 4, when the device screen rotates, the size of the target image is not changed, but the target image is kept at the original angle by rotating in the same rotation speed and in the opposite direction to the device. In this case, since the target image and the location of the device do not completely overlap, a blank area appears on the device screen.
And secondly, zooming the target image to enable the target image to be completely displayed in the screen of the equipment.
Specifically, the modes of displaying the target image in the device screen completely include two modes:
firstly, acquiring the screen size of equipment and the current angle of the equipment; and generating a control instruction for zooming the target image according to the screen size and the current angle of the equipment. Generating a control instruction to zoom the target image according to the screen size and the current angle of the device may include: determining the maximum size allowed by the target image when the target image is completely displayed at the current angle of the equipment; and generating a control instruction for zooming the target image according to the maximum size allowed when the target image is completely displayed at the current angle of the equipment. After the control instruction is executed, the target image is scaled to the situation shown in fig. 5, and as shown in fig. 5, the device continuously generates new control instructions along with the rotation of the device, and dynamically adjusts the target image based on the control instructions, so that the target image can be completely displayed in the screen of the device at the maximum size all the time. And generating a control instruction for zooming the target image to be matched with the screen of the equipment under the condition that the equipment rotates to the target angle. In the method, the size of the target image is dynamically changed along with the change of the angle of the equipment so as to ensure that the target image is completely displayed in the screen of the equipment in the maximum size. Assuming that the device is rectangular, the target angle may be that the device is rotated to a position where a designated edge of the device screen is parallel or perpendicular to a reference surface such as the ground.
Secondly, acquiring the maximum display size allowed when the target image is completely displayed under each rotation angle of the equipment; acquiring the minimum value of all the maximum display sizes; and generating a control instruction for zooming the target image according to the minimum value. According to the method, the size of the target image is adjusted only once, and the target image can be completely displayed on the screen of the equipment when the equipment rotates to any angle through once adjustment. For example, the device corresponds to the maximum display size allowed when a target image is completely displayed at each angle, determines a minimum value from the maximum display sizes allowed when the target image is completely displayed at each angle, and directly adjusts the target image to the minimum value, so that the target image can be completely displayed on the screen of the device no matter the device rotates to any angle. For example, of the maximum display sizes allowed when the target images corresponding to all the angles are completely displayed, the size value corresponding to the four angles of 45 °, 135 °, 225 °, and 315 ° between the device and the reference surface (e.g., horizontal plane) is the smallest, and then the size value corresponding to any one of the four angles is taken to generate the control instruction, and the target image is adjusted to the size value corresponding to any one of 45 °, 135 °, 225 °, and 315 ° based on the control instruction.
And thirdly, zooming the target image to ensure that a blank area (an area except the target image in the device screen) as shown in fig. 4 or 5 does not appear in the device screen.
In the second mode, the target image can be completely displayed, but a blank area still appears, and the third mode is a scheme provided for ensuring that no blank area appears in the screen of the device, and in the third mode, as shown in fig. 6, the target image is zoomed to a size shown by a dotted line box in fig. 6, and the area where the target image is located can completely wrap the area where the screen of the device is located without changing the angle of the target image, so that the device can be displayed in a full screen regardless of the angle to which the device is rotated by the target image zooming mode based on the screen size and the device angle of the device as shown in fig. 6. Specifically, the screen size of the equipment and the current angle of the equipment are obtained; determining the minimum size allowed by a target image which can enable the device at the current angle to be displayed in a full screen mode; and generating a control instruction for scaling the target image according to the minimum size. In the third mode, in the case that the current angle of the device is the target angle, a control instruction for zooming the target image to fit the screen of the device is generated.
It should be noted that the target angle mentioned in the second and third modes may refer to an angle when the preset edge of the screen is parallel or perpendicular to the reference plane (e.g., horizontal plane), and the preset edge of the screen may be any edge of the screen. The generation of the control instruction for scaling the target image to be adapted to the screen of the device mentioned in the second and third modes may refer to scaling the size of the target image to be completely the same as the size of the screen, so that the area where the target image is located and the area where the screen is located are completely overlapped, fig. 7 is a case where the device is located at a target angle, as shown in fig. 7, when the device is located at an angle at which the preset edge of the screen is parallel or perpendicular to the reference surface, the target image is completely and fully displayed in the device, and thus, full-screen display of the device can be achieved, and complete display of the target image can also be achieved.
It is understood that, in the above-mentioned manners, during the scaling of the target image, the center point of the target image and the device may be kept in a coincident state.
The beneficial effect of this application lies in: under the condition that the equipment rotates, the target image in the equipment does not rotate along with the equipment, but the target image in the equipment is kept at the original angle through the rotation in the opposite direction and at the same speed, so that the phenomenon that the picture is inclined in the screen rotating process is overcome through the mode, and the user experience is improved.
In one embodiment, the above step S11 can be implemented as the following step a 1:
in step a1, acquiring the current rotation speed and rotation direction of the device;
the above step S12 may be implemented as the following step a 2:
in step a2, a control command for rotating the target image in the same rotational speed and opposite rotational directions is generated based on the current rotational speed and rotational direction of the apparatus.
In the embodiment, the current rotation speed and the current rotation direction of the equipment are obtained under the condition that the rotation of the equipment is detected; and then generating a control instruction for rotating the target image in the same rotating speed and opposite rotating directions according to the current rotating speed and rotating direction of the equipment. Therefore, the target image in the equipment can be controlled by the control instruction to not rotate along with the equipment, and the original angle is kept.
In one embodiment, the above step S11 can be implemented as the following step B1:
in step B1, acquiring the screen size of the device and the current angle of the device;
the above step S12 may be implemented as the following step B2:
in step B2, a control instruction for zooming the target image is generated according to the screen size and the current angle of the device.
Because in this application, in order to avoid the problem of picture tilting in the rotation process of the device, the target image does not rotate along with the screen, therefore, in the rotation process of the device, a situation that only partial areas of the device and the target image overlap as shown in fig. 4 may occur, at this time, two problems may occur, the first problem is that the device cannot display in a full screen manner, a blank area may occur in the screen of the device, and the second problem is that the target image cannot be completely displayed, therefore, the embodiment provided in this application further solves all or at least part of the problems that a blank area occurs in the screen of the device and the target image cannot be completely displayed on the basis of the problem of picture tilting in the rotation process of the device. Specifically, in the present application, the above technical problem is solved by scaling the size of a target image displayed in a screen based on the screen size of a device and the current angle of the device.
In one embodiment, the above step B2 may be implemented as the following steps C1-C2:
in step C1, the maximum size allowed for the target image when displayed in its entirety at the current angle of the device is determined;
in step C2, a control instruction for scaling the target image is generated based on the maximum size allowed for the target image when it is fully displayed at the current angle of the device.
In the embodiment, the maximum size allowed when the target image is completely displayed at the current angle of the equipment is determined; and generating a control instruction for zooming the target image according to the maximum size allowed when the target image is completely displayed at the current angle of the equipment. After the control instruction is executed, the target image is scaled to the situation shown in fig. 5, and as shown in fig. 5, the device continuously generates new control instructions along with the rotation of the device, and dynamically adjusts the target image based on the control instructions, so that the target image can be completely displayed in the screen of the device at the maximum size all the time.
In one embodiment, the step C2 can be implemented as the following steps:
and under the condition that the current angle of the equipment is the target angle, generating a control instruction for zooming the target image to be matched with the screen of the equipment.
In this embodiment, in the case where the device is rotated to the target angle, a control instruction for zooming the target image to fit the screen of the device is generated.
For example, assuming that the device is rectangular, the target angle may be that the device is rotated to a position where a designated edge of the screen of the device is parallel or perpendicular to a reference surface such as the ground. The step of scaling the target image to the control instruction adapted to the screen of the device may be to scale the size of the target image to be completely the same as the size of the screen, so that the area where the target image is located is completely overlapped with the area where the screen is located, that is, when the device is located at an angle at which the preset edge of the screen is parallel or perpendicular to the reference surface, full-screen display and complete display can be achieved.
In one embodiment, as shown in FIG. 8, the above step S12 can be implemented as the following steps S81-S83:
in step S81, the maximum display size allowed when the target image is completely displayed at each rotation angle of the apparatus is acquired;
in step S82, the minimum value of all the maximum display sizes is acquired;
in step S83, a control command for scaling the target image is generated based on the minimum value.
In this embodiment, the size of the target image is adjusted only once, and the target image can be completely displayed on the screen of the device when the device rotates to any angle through one-time adjustment. For example, the device corresponds to the maximum display size allowed when a target image is completely displayed at each angle, determines a minimum value from the maximum display sizes allowed when the target image is completely displayed at each angle, and directly adjusts the target image to the minimum value, so that the target image can be completely displayed on the screen of the device no matter the device rotates to any angle.
For example, if the size value corresponding to the four angles of 45 °, 135 °, 225 °, and 315 ° included between the device and the reference surface (e.g., horizontal plane) is the smallest among the maximum display sizes allowed when the target images corresponding to all the angles are completely displayed, a control instruction is generated by taking the size value corresponding to any one of the four angles, and the target image is adjusted to the size value corresponding to any one of the angles of 45 °, 135 °, 225 °, and 315 ° based on the control instruction.
In one embodiment, the above step S11 can be implemented as the following step D1:
in step D1, acquiring the screen size of the device and the current angle of the device;
the above step S12 can be implemented as the following steps D2-D3:
in step D2, determining the minimum size allowed by the target image that enables full-screen display of the device at the current angle;
in step D3, a control instruction for scaling the target image is generated according to the minimum size.
In the above embodiment, a complete display of the target image is ensured, but the embodiment is to solve another problem related in the foregoing, that is, how to ensure a full-screen display of the device, in the embodiment, in a rotation process of the device, a screen size of the device and a current angle of the device are obtained; determining the minimum size allowed by a target image which can enable the device at the current angle to display in a full screen mode based on the screen size and the current angle of the device; and generating a control instruction for scaling the target image according to the minimum size.
As shown in fig. 6, the target image is zoomed to the size shown by the dotted line box in fig. 6, and the area where the target image is located can completely wrap the area where the screen of the device is located without changing the angle of the target image, so that the device can be displayed in a full screen no matter what angle the device is rotated by the target image zooming manner shown in fig. 6.
In one embodiment, the step D3 can be implemented as the following steps:
and under the condition that the current angle of the equipment is the target angle, generating a control instruction for zooming the target image to be matched with the screen of the equipment.
In one embodiment, the above steps of generating a control instruction for zooming the target image to fit the screen of the device in the case that the current angle of the device is the target angle may be implemented as the following steps:
and under the condition that the current angle of the equipment is the angle when the preset edge of the screen is parallel to or perpendicular to the reference surface, generating a control instruction for zooming the target image to be matched with the screen of the equipment.
In this embodiment, when the current angle of the device is an angle at which the preset edge of the screen is parallel to or perpendicular to the reference surface, a control instruction for zooming the target image to fit the screen of the device is generated, where generating the control instruction for zooming the target image to fit the screen of the device may refer to zooming the size of the target image to be completely the same as the size of the screen, so that the area where the target image is located is completely overlapped with the area where the screen is located, fig. 7 is a case where the device is at the target angle, as shown in fig. 7, when the device is at the angle at which the preset edge of the screen is parallel to or perpendicular to the reference surface, the target image is completely displayed in the device in a full screen, and full screen display of the device can be achieved, and complete display of the target image can also be achieved.
