Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the disclosure.

Furthermore, the drawings are merely schematic illustrations and are not necessarily drawn to scale. The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

The filter effect generation method in one embodiment of the present disclosure may be executed in a terminal device or a server. The terminal device may be a user terminal device, such as a mobile phone or a computer. When the filter effect generation method is executed on a server, the filter effect generation method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system comprises the server and a client device.

In an optional implementation manner, taking a cloud interaction system as an example, various cloud applications may be run under the cloud interaction system, for example: in an operation mode of filter effect generation based on a cloud interaction system, a generation main body of a filter effect and a display main body of the filter effect are separated, filter effect storage and generation of an image in a filter effect generation method are completed on a cloud server, and a client device is used for receiving and sending data and receiving and sending the image, for example, the client device can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; but the process of performing filter effect generation is at the server. When filter effect processing is carried out, a user operates a client device to send an operation instruction for selecting a target filter effect to a cloud server, the cloud server acquires an image according to the operation instruction, a target configuration file is called in response to the selection operation of the target filter of the user, a target filter effect is generated, data such as the target filter effect are coded and compressed, the data are returned to the client device through a network, and finally, decoding is carried out through the client device and a target filter effect picture is output.

In an optional implementation manner, taking the terminal device as an example, the local terminal device stores a parameter adjustable control for responding to a filter parameter adjusting operation of a user. The local terminal device is used for interacting with a user through a graphical user interface, namely, a filter effect related program is downloaded and operated through the electronic device conventionally. The manner in which the local terminal device provides the graphical user interface to the user may include a variety of ways, for example, it may be rendered for display on a display screen of the terminal or provided to the user by holographic projection. For example, the local terminal device may include a display screen for presenting a graphical user interface including a parameter-adjustable control and a filter effect screen, and a processor for running the filter effect-related program, generating a graphical user interface, and controlling display of the graphical user interface on the display screen.

The inventor finds that in the related filter effect generation method, pixel data and vertex data need to be subjected to various processing, for example, vertex data is processed in an evaluator to generate normal vectors, texture coordinates, spatial coordinates of points and the like, corresponding pixel information is generated through vertex operation and primitive assembly, the pixel information is subjected to rasterization processing to generate fragments used by a fragment shader, and a final color corresponding to each pixel is determined through the fragment shader, but when the vertex and the fragments are rendered, colors are overlapped, so that a target filter effect is different from a finally displayed filter effect; in addition, the principle of the related filter effect generation device is to write shader files and load the shader files into a rendering pipeline, so that the filter effect is achieved, however, the writing of shader files has a high professional requirement, and people who are not image processing professionals cannot perform related adjustment on the filter algorithm of an image, so that the filter effect development cost is high, and the development period is long.

In addition, the filter effect provided by the mobile terminal is more basic, and a user cannot adjust the filter algorithm to obtain various basic filter effects; meanwhile, based on the filter effect of professional image processing software, the filter effect is realized by writing shader files and loading the shader files into a rendering pipeline according to the principle, and the algorithm for writing the shader files is complex, so that the development cost of the filter effect is high, and the development period is long.

In view of one or more of the above problems, in the present exemplary embodiment, first, a filter effect generating method is provided, which may be applied to a terminal device having an interactive function or a server, and this is not particularly limited in this exemplary embodiment, and the following description will be made in detail by taking an example in which the terminal device executes the method.

Fig. 1 shows a flow diagram of a filter effect generation method according to an embodiment of the present disclosure; referring to fig. 1, the filter effect generating method may include the steps of:

step S110, responding to the selection operation of the target filter effect, and determining a target configuration file corresponding to the target filter effect;

step S120, determining original filter parameters corresponding to the target filter effect according to the target configuration file;

step S130, obtaining a pre-configured filter parameter table, and converting the original filter parameters into target filter parameters according to the filter parameter table;

step S140, generating the target filter effect according to the target configuration file and the target filter parameters.

According to the filter effect generation method in the present exemplary embodiment, on one hand, according to a target filter effect selected by a user, a target configuration file corresponding to the target filter effect is determined, an original filter parameter corresponding to the target filter effect is determined through the target configuration file, the target filter parameter corresponding to the target filter effect can be automatically matched based on a filter parameter table, a filter developer is not required to manually fill in the target filter parameter corresponding to the target filter effect, and the generation efficiency of the filter effect is improved; on the other hand, the filter parameter table can carry out parameter conversion on various filter parameters, so that the diversity of filter effects is improved.

Next, the filter effect generation method in the present exemplary embodiment will be further described.

In step S110, in response to a selection operation on a target filter effect, a target profile corresponding to the target filter effect is determined.

In one example embodiment of the present disclosure, the filter effect refers to implementing various special effects of an image, and the target filter effect may refer to a filter effect based on a user selection. The target filter effect may be a basic filter effect, for example, the basic filter effect may include a brightness filter effect, a contrast filter effect, a white balance filter effect, a LUT (Look-up-table) filter effect, a saturation filter effect, an exposure filter effect, a Gaussian blur filter effect, a dark angle filter effect, a white balance filter effect, a tone curve filter effect, a shadow highlight filter effect, a mixed mode soft light filter effect, a mixed mode hard light filter effect, a mixed mode deepening filter effect, a mixed mode dimming filter effect, a mixed mode color deepening filter effect, a mixed mode color dimming filter effect, a mixed mode linear filter effect, a mixed mode color filter effect, a mixed mode superimposing filter effect, a mixed mode difference filter effect, a mixed mode multiplicative filter effect, A mixed mode rejection filter effect, a mixed mode subtraction filter effect, a mixed mode division filter effect, a mixed mode color filter effect, and the like; the target filter effect may also be a complex filter effect obtained by combining at least 2 basic filter effects, for example, the complex filter effect may include a filter effect obtained by combining a luminance filter effect, a contrast filter effect, and a white balance filter effect, and of course, may also refer to a filter effect selected by another user, which is not particularly limited in this embodiment.

The target configuration file may refer to a file including configuration resources corresponding to a target filter effect, for example, the target configuration file may include filter parameter values for realizing the target filter effect, may also include material resources for realizing the target filter effect, may also include version information of the target filter effect, and of course, may also refer to a file including configuration resources corresponding to other target filter effects, which is not particularly limited in this embodiment.

Based on the operation of the target filter effect selected by the user, downloading a filter resource package through a wireless network or a limited network, analyzing the resource package, and searching a target configuration file corresponding to the target filter effect according to a directory of the configuration files.

For example, the target filter effect selected by the user is a shadow highlight filter effect, a configuration file set of all filter effects is read by downloading filter resource packages corresponding to all filter effects, and a configuration file corresponding to the shadow highlight filter effect is selected from the configuration file set as a target configuration file according to a directory of the configuration file set.

In step S120, an original filter parameter corresponding to the target filter effect is determined according to the target configuration file.

In an example embodiment of the present disclosure, the original filter parameter may refer to a filter parameter value corresponding to a target filter effect designed by a design end, for example, when the target filter effect is initially designed, the original filter parameter value corresponding to the design end is 50, and when the target filter effect needs to be displayed on a client, if the same effect as the design end is to be presented, the filter parameter value corresponding to the client may be 30 instead of 50, so that when the client uses the target filter effect, the original filter parameter value recorded by the design end needs to be converted.

In step S130, a pre-configured filter parameter table is obtained, and the original filter parameters are converted into target filter parameters according to the filter parameter table.

In an example embodiment of the present disclosure, the filter parameter table may be a mapping table that converts original filter parameters corresponding to a luminance filter effect and a basic mixed filter effect at a design end into filter parameters corresponding to a client; for example, if the target filter effect is a brightness filter effect, the filter parameter table may be a mapping table for converting the original intensity parameter into the target intensity parameter; if the target filter effect is a mixed-mode soft filter effect, the filter parameter table may also be a mapping table for converting the original soft filter parameters into target soft filter parameters; of course, the filter parameter mapping table may also be used to convert other original filter parameters into target filter parameters, which is not particularly limited in this embodiment.

The target filter parameter may be a filter parameter obtained by converting an original filter parameter through a filter parameter table, and the filter parameter may be displayed at the client, for example, at the design end, an original filter parameter value corresponding to the target filter effect is 50, and if a filter effect identical to the design end is to be presented, since standards for realizing the filter effect of different platforms are different, a filter parameter value corresponding to the client may be 30, and the original filter parameter value needs to be converted into the target filter parameter capable of forming the target filter effect at the client through the preset filter parameter table.

In particular, the basic filter effect may further include a basic mixed filter effect, for example, the basic mixed filter effect may include a soft light filter effect of a mixed mode, a bright light filter effect of the mixed mode, a deepening filter effect of the mixed mode, a dimming filter effect of the mixed mode, a color deepening filter effect of the mixed mode, a color dimming filter effect of the mixed mode, a linear filter effect of the mixed mode, a color filter effect of the mixed mode, a superimposed filter effect of the mixed mode, a differential filter effect of the mixed mode, a multiplicative filter effect of the mixed mode, a rejection filter effect of the mixed mode, a subtraction filter effect of the mixed mode, a division filter effect of the mixed mode, a filter effect of the mixed mode, and the like.

Since the filter parameter values of the basic mixed filter effect are generally expressed by percentages, the original filter parameters corresponding to the basic mixed filter effect at the design end are the target filter parameters corresponding to the basic mixed filter effect at the client end, for example, at the design end, the original filter parameters corresponding to the basic mixed filter effect are 25% (assuming that the filter parameter value range of the basic mixed filter effect at the design end is 0-100, and the original filter parameters are 25 at this time), then, at the client end, the target filter parameters corresponding to the basic mixed filter effect are still 25%, and conversion is not required through a filter parameter table (assuming that the filter parameter value range of the basic mixed filter effect at the client end is 0-80, and the original filter parameters are 20 at this time). It can be seen that although the original filter parameters of the basic hybrid filter effect are the target filter parameters and are not converted through the filter parameter table, the conversion of the filter parameters is substantially completed because the filter parameter values are expressed in percentage.

The target configuration file corresponding to the target filter effect is determined, the original filter parameters corresponding to the target filter effect are obtained from the target configuration file, and the target filter parameters corresponding to the target filter effect can be determined according to the filter parameter table, so that developers do not need to manually write the target filter parameters corresponding to the target filter effect, and the generation rate of the target filter effect is improved; in addition, the filter parameter table accurately maps the relationship between the original filter parameters and the target filter parameters, so that the problem of difference of filter effects realized by different platforms is solved, and the high restoration of the filter effects is realized.

In step S140, a target filter effect is generated according to the target configuration file and the target filter parameters.

In an example embodiment of the present disclosure, a target configuration file is determined according to a target filter effect, an original filter parameter corresponding to the target filter effect is determined in the target configuration file, a target filter parameter corresponding to the target filter effect can be determined through a filter parameter table, and the target filter effect can be generated based on the target configuration file and the target filter effect parameter.

For example, the target filter effect is a combined filter effect of a brightness filter effect and a vignetting filter effect, the target configuration file is a configuration file of the brightness filter effect and the vignetting filter effect, the original brightness filter parameter of the brightness filter effect is 30 according to the target configuration file, the original vignetting filter parameter of the vignetting filter effect is 25, the target filter parameter corresponding to the original brightness filter parameter of 30 in the filter parameter table is 20, the target filter parameter corresponding to the original vignetting filter parameter of 25 is 15, the target filter effect can be generated based on the target configuration file and the target filter parameter of the target filter effect, and the effect obtained by selecting when the user image is processed is achieved.

In this example embodiment, after responding to the selected target filter effect, the base set of filters for the target filter effect may be determined by the steps in fig. 2:

in step S210, in response to detecting that the target filter effect is a complex filter effect, determining a plurality of basic filter effects corresponding to the complex filter effect and a stacking order corresponding to the plurality of basic filter effects according to the target configuration file;

and S220, overlapping the multiple basic filter effects according to the overlapping sequence to obtain a basic filter group, wherein the basic filter group is a target filter effect.

In this embodiment, the complex filter effect may refer to a filter effect of a combination of at least 2 basic filter effects, which may be a combined filter effect of a luminance filter effect and a contrast filter effect, a combined filter effect of a shadow highlight filter effect, a sharpening filter effect, and a mixed-mode color deepening filter effect, a combined filter effect of a mixed-mode soft light filter effect and a mixed-mode color filter, and of course, a filter effect of a combination of other basic filter effects, which is not particularly limited in this embodiment.

The stacking sequence may refer to a combination sequence of a plurality of basic filter effects, for example, may refer to stacking a shadow highlight filter effect on a saturation filter effect, or may refer to stacking a saturation filter effect on a shadow highlight filter effect, or may refer to a combination sequence of other multiple basic filters; wherein, the combination sequence is different, and the final achieved target filter effect is also different.

The basic filter group (target filter effect) may refer to a filter group composed of at least 2 basic filter effects in a stacking order, for example, if the detected target filter effect is a combined filter effect of a shadow highlight filter effect and a saturation filter effect, the basic filter group is composed of the shadow highlight filter effect and the saturation filter effect, of course, the basic filter group may also be composed of other basic filter effects, and this embodiment is not particularly limited to this.

For example, the target filter effect is a filter effect obtained by superimposing a saturation filter effect on a shadow highlight filter effect, and then the basic filter group is composed of the shadow highlight filter effect and the saturation filter effect, so that the superposition sequence of the basic filter group corresponding to the target filter effect can be determined according to the target configuration file, and the filter effect obtained by superimposing the saturation filter effect on the shadow highlight filter effect is superimposed on the shadow highlight filter effect, and the shadow highlight filter effect and the saturation filter effect are superimposed, so that the corresponding target filter effect can be obtained, and the generation efficiency of the target filter effect is improved.

In this example embodiment, after responding to the selected target filter effect, the update of the target filter effect may be achieved by the steps in fig. 3:

step S310, generating a parameter adjustable control corresponding to a target filter effect according to the target filter parameter corresponding to the target filter effect;

step S320, responding to the adjustment operation on the parameter adjustable control, and determining the updated target filter parameter;

and step S330, updating the target filter effect according to the updated target filter parameter.

In this embodiment, the parameter-adjustable control may be a control capable of adjusting a target filter parameter, for example, the parameter-adjustable control may be an adjustable control for dragging the slider left and right to adjust the target filter parameter, or an adjustable control for adjusting the target filter parameter through a "+" - "button, and of course, the parameter-adjustable control may also be a control for adjusting the target filter parameter through a voice instruction or a gravity sensing manner, which is not limited in this example. The multiple filter parameters corresponding to the target filter effect may be adjusted by the parameter-adjustable control, for example, the parameter-adjustable control may be a parameter-adjustable control for adjusting a saturation parameter of the target filter effect, a parameter-adjustable control for adjusting a brightness parameter of the target filter effect, a parameter-adjustable control for adjusting a sharpening parameter of the target filter effect, or a parameter-adjustable control for adjusting other filter parameters, which is not particularly limited in this embodiment.

For example, the target filter effect is a combined filter effect of a brightness filter effect and a dark corner filter effect, an original brightness filter parameter of the brightness filter effect and an original dark corner filter parameter of the dark corner filter effect can be known through a target configuration file, a target filter parameter corresponding to the original brightness filter parameter matched in a filter parameter table is 20, a target filter parameter corresponding to the original dark corner filter parameter is 15, however, the generated target filter effect does not meet the user requirement, a user can increase the brightness filter parameter to 22 and the dark corner filter parameter to 20 by clicking or dragging a parameter adjustable control, obtain an updated target filter parameter in response to the operation of the user adjusting parameter adjustable control, and update the target filter effect according to the updated target filter parameter.

In this embodiment, the target filter effect may include a basic filter effect supporting intensity adjustment, and the intensity adjustment of the target filter effect may be realized through the steps in fig. 4:

step S410, responding to the intensity parameter adjusting operation on the parameter adjustable control, and adjusting the original intensity information of a plurality of basic filter effects corresponding to the complex filter effect;

step S420, obtaining target intensity information of the complex filter effect according to the original intensity information of the multiple basic filter effects to generate the complex filter effect with adjusted intensity.

In this embodiment, the original intensity information may refer to a display degree corresponding to the target filter effect before the intensity parameter adjustment operation, for example, the original intensity information may refer to a display degree of an original brightness parameter of the target filter effect, a display degree of a saturation parameter of the target filter effect, a display degree of an original contrast parameter of the target filter effect, or a display degree of other filter parameters of the basic filter effect, which is not particularly limited in this embodiment.

The target intensity information may refer to a display degree of the target filter effect generated after the intensity adjustment is performed on the target filter effect, for example, the target intensity information may refer to a display degree of a target brightness parameter of the target filter effect, a display degree of a target saturation parameter of the target filter effect, a display degree of a target contrast parameter of the target filter effect, and certainly, a display degree of other filter parameters of the target filter effect, which is not particularly limited in this embodiment.

For example, the target filter effect may be a combined filter effect of a brightness filter effect and a dark corner filter effect, and the user may adjust intensity information of a brightness parameter on the parameter-adjustable control, and obtain a display degree of the brightness filter effect and an original brightness parameter corresponding to the dark corner filter effect in response to an operation of the user on the brightness parameter-adjustable control, where if the original intensity information of the brightness parameter corresponding to the brightness filter effect is 30, the original intensity information of the brightness parameter corresponding to the dark corner filter effect is 20, the target brightness parameter corresponding to the brightness filter effect corresponding to the brightness parameter is 30 according to the original intensity information of the brightness parameter, and the original intensity information of the brightness parameter is the target brightness parameter corresponding to the dark corner filter effect corresponding to 20, and obtain target intensity information corresponding to the brightness parameter of the target filter effect; further, a target filter effect is generated based on target intensity information corresponding to the luminance parameter of the target filter effect.

In this embodiment, the target filter effect includes a basic hybrid filter effect that does not support intensity parameter adjustment, and the intensity adjustment of the target filter effect can be realized through the steps in fig. 5:

step S510, responding to the intensity parameter adjustment operation of the basic mixing filter effect on the parameter adjustable control, and acquiring a configuration file corresponding to the basic mixing filter effect; wherein the configuration file comprises shader programs;

step S520, rendering the basic hybrid filter effect through the shader program to obtain the basic hybrid filter effect after the intensity adjustment, thereby achieving the intensity adjustment of the target filter effect.

In this embodiment, the basic mixed filter effect may refer to a basic filter effect in a mixed mode, may refer to a soft light filter effect in the mixed mode, may refer to a color deepening filter effect in the mixed mode, may refer to a color filtering filter effect in the mixed mode, and may also refer to a filter effect in other mixed modes, which is not particularly limited in this embodiment.

The shader program refers to a program that can render a target filter effect, and may refer to a vertex shader program, a fragment shader program, or other shader programs that render a target filter effect, which is not limited in this embodiment.

Preferably, in the target filter effect including the basic mixed filter effect, the intensity adjustment of the target filter effect is realized by determining the basic mixed filter effect in the target filter effect, acquiring a configuration file corresponding to the basic mixed filter effect, and loading a shader program through the configuration file.

For example, according to an operation of a user on a parameter-adjustable control, it is determined that a basic filter effect corresponding to a target filter effect is a mixed-mode soft light filter effect, a configuration file corresponding to the mixed-mode soft light filter effect is obtained, a shader program corresponding to the mixed-mode soft light filter effect is called in the configuration file, so that intensity adjustment of the target filter effect can be achieved, and intensity adjustment of a filter effect which does not support intensity adjustment originally is achieved by loading the shader program corresponding to the mixed-mode filter effect.

In this example embodiment, fig. 6 schematically shows a flow chart of a target filter effect generation process according to an embodiment of the present disclosure;

referring to fig. 6, in step S601, in response to a target filter effect operation selected by a user, a target configuration file corresponding to the target filter effect is determined;

step S602, based on the target configuration file, determining the original filter parameters corresponding to the target configuration file;

step S603, determining target filter parameters corresponding to the original filter parameters in the target configuration file according to a preset filter parameter table;

step S604, generating a target filter effect and a parameter adjustable control corresponding to the target filter effect according to the target filter parameter;

step S605, judging whether intensity adjustment is needed to be carried out on the target filter effect, executing step S606 if intensity adjustment is needed to be carried out on the target filter effect, and executing step S614 if intensity adjustment is not needed to be carried out on the target filter effect;

step S606, determining whether the target filter effect includes a basic mixed filter effect, the target filter effect including the basic mixed filter effect executing step S607, the target filter effect not including the basic mixed filter effect executing step S611;

step S607, loading a shader program based on a configuration file corresponding to the basic mixed filter effect;

step S608, responding to the intensity adjusting operation of the user on the parameter adjustable control, and acquiring the original intensity information of the basic filter effect;

step S609, obtaining target intensity information of the complex filter effect based on the original intensity information of the basic filter effect;

step S610, rendering the target filter effect through a shader program based on the target intensity information of the complex filter effect to obtain the target filter effect after intensity adjustment;

step S611, responding to the intensity parameter adjusting operation on the parameter adjustable control, and adjusting the original intensity information of a plurality of basic filter effects corresponding to the target filter effect;

step S612, acquiring updated target intensity information of the basic filter effect based on the original intensity information of the basic filter effect;

step S613, updating the target filter effect based on the target intensity information of the basic filter effect;

step S614, in response to the adjustment operation on the parameter adjustable control, determining the original filter parameters corresponding to the adjusted target filter effect;

step S615, based on the original filter parameters and the filter parameter table, determining updated target filter parameters;

and step S616, updating the target filter effect according to the updated target filter parameters and the target configuration file.

In this embodiment, a user may select a basic filter effect as a target filter effect, or may select a combined filter effect of multiple filter effects as the target filter effect, determine a target configuration file corresponding to the target filter effect in response to a selection operation of the user target filter effect, determine an original filter parameter for generating the target filter effect according to the target configuration file, and generate the target filter effect based on the target filter parameter; and if the target filter effect is the combined filter effect of the multiple basic filter effects, acquiring target filter parameters of the target filter effect according to a preset filter parameter table.

For example, the target filter effect selected by the user is a saturation filter effect, a configuration file corresponding to the saturation filter effect is obtained as a target configuration file in response to a target filter effect operation selected by the user, an original saturation parameter corresponding to the saturation filter effect is determined based on the target configuration file, and if the original saturation parameter is 43, the target filter effect is generated according to the target filter parameter by matching the original saturation parameter to be 28 corresponding to the original saturation parameter to be 43 based on a preset filter parameter table.

Similarly, if the target filter effect selected by the user is a combined filter effect of at least 2 basic filter effects, a configuration file corresponding to each basic filter effect is obtained in response to the selection operation of the target filter effect of the user, the configuration files corresponding to all the basic filter effects in the target filter effect are used as target configuration files, the superposition sequence of the basic filter effects and the original filter parameters of a plurality of basic effects are determined according to the target configuration files, the target filter parameters corresponding to each basic filter effect are obtained based on the filter parameter table, and the target filter effect is generated according to the target filter parameters corresponding to each basic filter effect and the target configuration files.

Preferably, the parameter adjustable control is generated based on the target filter parameter; when the adjustment operation of a user on the parameter adjustable control is detected, acquiring the original filter parameters of the adjusted target filter effect, and determining the target filter parameters corresponding to the original filter parameters of the target filter effect; and updating the target filter effect based on the updated target filter parameters.

For example, the target filter effect selected by the user is a saturation filter effect, if the original saturation parameter of the target filter effect is 43, the target saturation parameter corresponding to the original saturation parameter 43 is 28 obtained based on a preset filter parameter table, and the target filter effect is generated according to the target filter parameter; however, the saturation of the generated target filter effect does not meet the requirement of the user, the user can respond to the adjustment operation of the saturation parameter adjustable control of the user by clicking or dragging the adjustable control for adjusting the saturation parameter to obtain the original saturation parameter corresponding to the saturation filter effect, if the original filter parameter is 60, the target saturation parameter corresponding to the saturation filter effect is determined to be 43 based on the filter parameter table, and the target filter effect is updated according to the target saturation parameter and the target configuration file.

Optionally, the target filter effect may be a complex filter effect composed of a plurality of basic filter effects, if an adjustment operation of a user on an intensity parameter adjustable control of the target filter effect is detected, original intensity information of the target filter effect is obtained, target filter information corresponding to the target filter effect (the complex filter effect) is obtained according to the original filter information of the basic filter effect, and the target filter effect is updated according to the updated target intensity information and the target configuration file; particularly, when the target filter effect is the filter effect superposed by the basic mixing filter, in response to the operation of the intensity parameter adjustable control by the user, a configuration file corresponding to the basic mixing filter effect is obtained, the original intensity information of the basic mixing filter effect is determined, a shader program is loaded through the configuration file of the basic mixing filter effect according to the target intensity information of the basic mixing filter effect, and the target filter effect is updated according to the target intensity information of the basic mixing filter effect.

For example, the target filter effect selected by the user is to superimpose a dark angle filter effect on the brightness filter effect, the user can adjust the intensity information of the contrast parameter on the parameter-adjustable control, and it can be known through the target configuration file that the original intensity information of the contrast parameter of the brightness filter effect is 35 and the original intensity information of the contrast parameter of the dark angle filter effect is 67; and then, obtaining target intensity information of the target filter effect according to the original intensity information of the contrast parameter of the brightness filter effect and the original intensity information of the contrast parameter of the dark angle filter effect, and generating the target filter effect based on the target intensity information of the target filter effect. However, the brightness of the target filter effect does not meet the requirements of the user, the user can obtain the updated brightness filter effect and the original intensity information corresponding to the dark corner filter effect by clicking or dragging the brightness parameter adjustable control in response to the operation of adjusting the brightness parameter adjustable control by the user, the original brightness intensity information of the brightness filter effect after adjusting the brightness parameter adjustable control is 50, the original brightness intensity information of the dark corner filter effect is 73, and the target intensity information of the brightness parameter of the target filter effect is obtained according to the original intensity information of the brightness parameter of the brightness filter effect and the original intensity information of the brightness parameter of the dark corner filter effect; and finally, updating the target filter effect according to the target intensity information of the brightness parameter of the target filter effect and the configuration file corresponding to the target filter effect.

Particularly, if the target filter effect selected by the user is a filter effect including a basic mixed filter effect, when the user needs to adjust the brightness of the target filter effect, a configuration file corresponding to the basic mixed filter effect needs to be acquired, and a shader program is loaded through the configuration file.

In summary, on one hand, the user can select the basic filter effect as the target filter effect, and also can select the filter effect superposed by multiple basic filter effects as the target filter effect, so that the richness of the filter effect is increased; on the other hand, a target filter parameter corresponding to an original filter parameter of a target filter effect can be determined through a pre-configured filter parameter table, and a parameter adjustable control corresponding to the target filter parameter is generated; on the other hand, when the complex filter effect contains the basic mixed filter effect, the shader program can be loaded through the configuration file corresponding to the basic mixed filter, the intensity of the complex filter effect is adjusted through executing the shader program, shader language does not need to be written, optimization of the target filter effect is achieved, intensity adjustment of the mixed filter effect which does not support intensity adjustment in the past is achieved, and development cost and development period of the filter effect are reduced.
