It has been found that the zoom adjustment interaction manner in the related art is mostly manual adjustment, for example, zoom magnification may be scaled by pinching or expanding two fingers on a touch screen of a mobile terminal. When the user is performing zooming operation through the touch screen, if the zooming operation is performed from the starting point x1 to the ending point x2, the corresponding focal length can be changed from the current value z1 to the result value z2 through conversion.

To at least partially address one or more of the above-mentioned problems, as well as other potential problems, the present disclosure provides at least one zoom control scheme to achieve smooth zooming.

For the sake of understanding the present embodiment, first, a detailed description will be given of a zoom control method disclosed in an embodiment of the present disclosure, where an execution body of the zoom control method provided in the embodiment of the present disclosure is generally an electronic device having a certain computing capability, and the electronic device includes, for example: the terminal device, or other processing device, may be a User Equipment (UE), a mobile device, a User terminal, a handheld device, a computing device, a vehicle mount device, a wearable device, or the like. In some possible implementations, the zoom control method may be implemented by way of a processor invoking computer readable instructions stored in a memory.

Referring to fig. 1, a flowchart of a zoom control method according to an embodiment of the present disclosure is shown, where the method includes steps S101 to S103, where:

s101: responding to a zooming trigger instruction aiming at a target scene image, and acquiring a starting point trigger parameter value and an ending point trigger parameter value in the zooming trigger instruction;

s102: whether a cycle cut-off condition is reached;

if yes, ending; if not, executing S103;

s103: determining a current trigger parameter value required to be adopted for the current image rendering based on the last trigger parameter value adopted for the previous image rendering and the end point trigger parameter value; the current trigger parameter value is between the last trigger parameter value and the end point trigger parameter value; and performing current image rendering based on the current trigger parameter value to obtain a zoomed frame of target scene image.

In order to facilitate understanding of the zoom control method provided by the embodiments of the present disclosure, a detailed description is first given of an application scenario of the method. The zoom control method in the embodiment of the disclosure can be mainly applied to the field of equipment display, and the multi-frame scene image obtained based on cyclic rendering has a good zoom effect, so that the viewing fluency is remarkably improved.

Considering that the related art in the manual zooming process, when a user is performing a zooming operation through a touch screen, if changing from a start point x1 to an end point x2, the corresponding focal length may be changed from the current value z1 to the result value z2 through a transition. The whole switching process is discontinuous, which results in that smooth zooming cannot be realized, and viewing smoothness is affected.

In order to solve the above-mentioned problems, the embodiments of the present disclosure provide an iterative loop zoom scheme, which determines a current trigger parameter value by a last trigger parameter value and a pointed end trigger parameter value, and gradually approaches the end trigger parameter value during a loop, so as to achieve a smooth zoom effect.

Before the zoomed image is rendered, a zoom trigger instruction for the target scene image may first be responded, and a start trigger parameter value and an end trigger parameter value in the instruction are acquired.

The related target scene image may be a related scene image displayed on the user side, for example, may be a related scene image displayed on a photographing interface in the process of recording video, or may be a navigation image displayed on a related Application (APP), etc., which may not be limited in particular.

In practical applications, the target scene image may be a single image, an image segment formed by multiple images, or a video stream formed by a continuous image, and the zooming principle is similar regardless of the image sources, and the single image is used for illustration.

In addition, the zoom trigger instruction may be triggered in the case of performing a sliding operation with respect to the target scene image in the user side, where the sliding operation may be an action of pinching or expanding on the device touch screen, for example, a zoom multiple is decreased during pinching; the method can also be triggered under the condition of executing double-click operation on the target scene image in the user side, wherein the double-click operation can be that the zooming is executed once every double-click under the condition of a preset zooming multiple; in addition, the embodiments of the present disclosure may be implemented based on other triggering operations, which are not limited in detail herein.

Here, the start trigger parameter value and the end trigger parameter value may be obtained from a zoom trigger instruction, for example, in the process of pinching zoom, the start trigger parameter value may be a trigger parameter value at an initial position captured by a user when touching a finger to a target scene image displayed on a user side screen and triggering zoom, and the end trigger parameter value may be a trigger parameter value at an end position pointed in the process of pinching. The trigger parameter value may be a trigger coordinate value for triggering the target scene image, or may be a lens zoom value obtained by transforming based on the trigger coordinate value.

It should be noted that, the end point trigger parameter value may be a constant value, for example, a zoom operation performed once the user is pinching may correspond to a determined end point trigger parameter value; in addition, the end point trigger parameter value may be a variable value, for example, in the operation of performing zooming multiple times by kneading multiple times by the user, the end point trigger parameter value may be a plurality of variable values, and in practical application, the plurality of variable parameter values may be larger and larger, may be larger and smaller, may be smaller and larger, may be other variable trends, and may be determined in combination with specific zooming situations without specific limitation.

In the process of executing one zoom, a plurality of zoomed images can be rendered in unit time, the plurality of zoomed images correspond to a cyclic rendering process, namely, a current trigger parameter value needed to be adopted by the current image rendering is determined based on the last trigger parameter value adopted by the previous image rendering and the end point trigger parameter value, and a zoomed frame of target scene image obtained by the current image rendering is processed based on the current image rendering.

The cycle cutoff condition may be that the preset cycle number is reached, and the relevant cycle number may be determined in combination with the frame rate, and in addition, considering that the current trigger parameter value and the end point trigger parameter value gradually approach, the cycle cutoff condition may be that the difference between the two parameter values (i.e., the current trigger parameter value and the end point trigger parameter value) is sufficiently small, or may be other cutoff conditions, which are not particularly limited herein.

Considering the key role of the current trigger parameter value to be determined for each rendering on the zooming operation, the following description may focus on the determination process of the current trigger parameter value, which may be implemented specifically by the following steps:

step one, carrying out difference value operation on the end point trigger parameter value and the last trigger parameter value to obtain a first operator; and taking the last trigger parameter value as a second operator;

and step two, determining the current trigger parameter value based on the first operator and the second operator.

Here, the current trigger parameter value may be determined based on the first operator and the second operator. Considering the influence of different zooming change speeds on zooming effects, the current trigger parameter value can be determined by combining preset zooming coefficients, and the method can be realized by the following steps:

step one, obtaining a preset zoom coefficient; the zoom coefficient is used for representing the speed of zooming between frames;

step two, multiplying the first operator and the zoom coefficient to obtain an operation result;

and thirdly, carrying out addition operation on the operation result and the second operator to determine the current trigger parameter value.

Here, the first operator and the zoom coefficient may be multiplied to determine the zoom amplitude, and then based on an addition operation between the result obtained by the operation and the second operator, a current trigger parameter value that is finally required is determined, and the current trigger parameter value gradually approaches to the end trigger parameter value as the number of cycles increases.

To facilitate an understanding of the above loop rendering process, a further description may follow in conjunction with specific formulas and an example.

It is known that: the final target value F (i.e. the end point trigger parameter value), the actual value C (i.e. the last trigger parameter value) before the current cycle, the new value T (i.e. the current trigger parameter value) needed after the current cycle, and the advancing speed S (i.e. the preset zoom factor), wherein the relative S generally takes the values of 0-1, and the larger and the faster.

A cycle t=c+ (F-C) S can be first established based on the above information.

Here, in a certain cycle a, the new value required after the present cycle is set to a value intermediate between the final target value F and the actual value C before the present cycle, that is:

Ta＝Ca+(F-Ca)*s

in the next cycle b, tb=cb+ (F-Cb) x s, wherein: cb is Ta of last cycle

The following description may be made in connection with a specific example.

For example, the current value is 0, the final target value is 100, and the forward speed is 0.5. At this time:

cycle 1:

new value=0+ (100-0) 0.5=50 required after this cycle;

cycle 2:

new value required after this cycle = 50+ (100-50) 0.5 = 75;

cycle 3:

new value required after this cycle = 75+ (100-75) 0.5 = 87.5;

……

gradually approaching 100 this final target value.

Based on the above examples, it can be seen that the embodiments of the present disclosure combine multiple cycling processes to achieve better zoom effects.

According to the zoom control method provided by the embodiment of the disclosure, the zoomed multi-frame target scene images can be displayed on the user side frame by frame, so that smooth zoom effects can be checked on the user side.

In addition, the picture display method provided by the embodiment of the disclosure can be applied to various user terminals. Considering AR technology as a technology for increasing the perception of the real world by a user through information provided by a computer system, virtual information can be applied to the real world, and virtual special effects, scenes and the like generated by a computer can be superimposed into the real scenes which can be watched by the user, so that mutual complementation of the two kinds of information is realized. Based on this, the user side may be the head-mounted AR glasses, so that the head-mounted AR glasses can display the combined real and virtual pictures in front of the eyes of the user, so as to enhance the experience of the user.

In order to better adapt to the AR display effect, in the process of performing image display after zooming, the following steps can be combined to realize:

step one, obtaining a virtual special effect generated aiming at a target scene image;

and step two, superposing the virtual special effect on the zoomed target scene image to obtain a superposed picture, and displaying the superposed picture on the user side.

Here, the virtual special effect generated for the current scene picture may be superimposed in the zoomed target scene image to make the presented fusion picture more immersive. The virtual special effect may be a related AR special effect determined by performing scene or target recognition on the current scene image, for example, in an actual application scene of cooking by a user, a product manufacturing process and the like may be used as the virtual special effect to be superimposed on the actual cooking image, so as to improve the practicability of the AR glasses.
