Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The sound effect adjusting method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 and the server 104 communicate via a network. The terminal 102 autonomously collects screen content to obtain a plurality of frames of screen images. Wherein the content of the screen play is sent from the server 104 to the terminal 102 via the data communication connection. The terminal 102 recognizes the content of the screen image, generates a recognition result for the screen image, and further generates a predicted content scene list according to the recognition result. The terminal 102 matches a content scene corresponding to the screen content from the predicted content scene list according to the system operation information by acquiring the system operation information of itself. And then the terminal 102 dynamically adjusts the original sound effect based on the content scene to generate a target sound effect according with the content scene. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and television products, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a sound effect adjusting method is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:
step S202, screen content is collected, and multiple frames of screen images are obtained.
Specifically, the terminal acquires the image content being played by the screen in real time to obtain a multi-frame screen image composed of the image content played by the screen.
Further, the terminal can be a television product, and when the user uses the television product, the television product can acquire the screen content corresponding to the program selected and played by the user in real time, and extract the screen content to obtain a multi-frame screen image. The television product can also collect image content played by a screen in a preset extraction period to obtain a plurality of frames of screen images.
And step S204, identifying the content of the screen image, and generating a predicted content scene list according to the identification result.
Specifically, a television product as a terminal generates an identification result of a corresponding screen image by identifying the contents of the extracted multiple frames of screen images. The content scenes expressed by the extracted multi-frame screen images can be dynamically identified by utilizing an AI artificial intelligence technology, wherein the content scenes can comprise that a user plays music, the user watches movie and television programs, the user watches sports programs, the user watches news programs, the user plays games and the like.
The identification operation aiming at the collected multi-frame screen image comprises image content identification at local, more accurate content identification is carried out by sending the image to a cloud server through a network, the identified content in the latest period of time is referred again according to the content of the current image, and the current content scene is determined by applying a weighted big data matching algorithm and rules. The image of the near period refers to the identification condition of other images which are cached in front of the frame image, namely the reference of the continuous most-recently-used content.
Further, the extracted multi-frame screen images are continuous dynamic images with preset duration. Compared with the traditional static image identification operation focusing on the moment, the accuracy of the generated identification result can be further improved by extracting continuous multi-frame screen images and then carrying out content identification operation. And analyzing the generated identification result to obtain a predicted content scene list, namely a content scene to which the content played by the current screen possibly belongs.
In one embodiment, for example, a user plays music and views pictures simultaneously, that is, the user searches for pictures on a television product for viewing, the background simultaneously opens music playing software for playing music, and the searched pictures are static scenery pictures or people pictures. When the current screen content is collected and identified, the identification result is a static landscape or a portrait, the obtained predicted content scene list may include different content scenes such as when the user watches movie and television programs, and the pictures are in a static state, and may also be used as a protection interface of a music application program, and may also include different content scenes such as when the user plays music.
And step S206, acquiring system operation information, and matching a content scene corresponding to the screen content from the predicted content scene list according to the system operation information.
Specifically, the system operation information includes play state information and interface information, and a current play state of the screen can be determined according to the play state information, where the current play state includes different states such as playing video, playing audio, and displaying pictures. The type of the application program currently running in the television product can be determined according to the interface information, wherein the type of the application program comprises a movie application program, a game application program, a music application program, a shopping application program and the like.
Further, according to whether the current playing state is video playing, audio playing or picture displaying, and by combining with the currently running application program, whether the video application program, the game application program or the music application program is running, the content scene matched with the system running information, namely the playing state information and the interface information, is determined from the predicted content scene list.
In an embodiment, for example, when a user plays music and views a picture at the same time, by acquiring system operation information including play state information and interface information, since the user views the picture, it is determined that a current play state is a display picture, and when it is detected that an application program currently running in the system is a music application program, it is determined that the user is playing music. Due to the fact that corresponding music sound effects do not need to be set when the picture is viewed, the content scene needing sound effect adjustment can be further determined to be the music played by the user.
In another embodiment, for example, the user is playing a game program, that is, the application program opened by the user is a movie application program, and the program selected to be played is the game program. Acquiring screen content to obtain multi-frame screen images related to a game, identifying the multi-frame screen images to obtain an identification result, and obtaining a predicted content scene list according to the identification result, wherein the predicted content scene list comprises a movie and television program watched by a user or a game played by the user. By acquiring system operation information including playing state information and interface information, when a user opens a movie application program when playing a game program, the current playing state is determined to be a playing video, and the type of the currently running application program is determined to be a movie application program. And (4) integrating the identification result of the image content and the system operation information for judgment, wherein the more accurate content scene matched from the predicted content scene list is the video program watched by the user.
Step S208, based on the content scene, dynamically adjusting the original sound effect to generate a target sound effect according with the content scene.
Specifically, before the sound effect adjustment operation is performed, the sound effect applied by the television product is the preset original sound effect. The original sound effect is a conventional sound effect of a television product, and can be used in different content scenes, but the sound effect cannot meet all content scenes, and the optimal expected sound effect of a user in different content scenes cannot be achieved. There is therefore a need for dynamic adjustment of the original sound effects based on the content scene to meet the best desired sound effects in the current content scene.
Further, an original configuration parameter list corresponding to the original sound effect is extracted, the target parameter value of each sound effect parameter is determined according to the determined content scene, and meanwhile the original sound effect parameter to be adjusted is determined from the original configuration parameter list according to the content scene. And then adjusting the original sound effect parameters to be adjusted according to the target parameter values to generate adjusted sound effect parameters, and generating the target sound effect which accords with the content scene according to the adjusted sound effect parameters.
In the sound effect adjusting method, a plurality of frames of screen images are obtained by collecting screen contents, the contents of the screen images are identified, and a predicted content scene list is generated according to the identification result. By acquiring the system operation information and carrying out comprehensive judgment according to the system operation information, matching a more accurate content scene corresponding to the screen content from the predicted content scene list, and further dynamically adjusting the original sound effect based on the content scene to generate a target sound effect according with the content scene. Need not user's manual regulation, avoid manual regulation audio relatively poor and lead to the problem of repeated operation, further improve sound audio and adjust efficiency.
In an embodiment, as shown in fig. 3, the step of generating the target sound effect conforming to the content scene, that is, the step of dynamically adjusting the original sound effect based on the content scene to generate the target sound effect conforming to the content scene specifically includes the following steps corresponding to S302 to S308:
step S302, an original configuration parameter list corresponding to the original sound effect is extracted.
Specifically, before sound effect adjustment operation is performed, sound effect applied to a television product is preset original sound effect, original configuration parameters and corresponding parameter values corresponding to the original sound effect are stored in a local database of the television product in advance, and when sound effect adjustment operation is required based on a content scene, an original configuration parameter list corresponding to the original sound effect can be extracted from the local storage, wherein the original configuration parameter list comprises the original configuration parameters and the original parameter values corresponding to the configuration parameters.
The components for determining the sound quality comprise tone, timbre, volume and timbre, wherein the tone is determined by the frequency spectrum of the sound wave, represents the high and low of the sound frequency and is related to the vibration times of the sound source per second. A low pitch indicates a low vibration frequency and a deep sound, and a high pitch indicates a high vibration frequency and a sharp sound. The volume is determined by the amplitude of the sound wave, which means the intensity or loudness of the sound, and the intensity of the marking sound is related to the magnitude of the vibration amplitude of the sound source, and too weak causes the sound to be inaudible, and too strong causes the sound to be unacceptable for human ears.
The tone is determined by the waveform envelope of the sound waves, the tones representing the sounds used in music, their harmonic composition and the envelope of the waveform, including the transients of the tone start and end, determine the characteristics of the tones, i.e. the tone. The sound quality can be determined by the growth and decay process of the sound, and the difference of the sound spectrum corresponding to different sound quality shows that the intensity distribution of the spectral line is different. The timbre is determined by the frequency spectrum of the sound wave, refers to the color and the characteristics of the sound, is related to the frequency spectrum of the vibration of the sound source, can take the tone as the symbol of a single frequency, and can be represented as the expression of a composite frequency consisting of a plurality of frequencies. The fundamental frequency component in the sound spectrum forms the fundamental tone of the sound, the pitch can be determined by the height of the fundamental frequency, other components in the sound spectrum are overtones, the overtones and the fundamental tone are in a multiple relation, and the tone color is determined by the structure of the overtones.
Further, excitation adjustment, pressure limit adjustment, noise reduction adjustment, delay adjustment, and equalization adjustment may be performed for each configuration parameter. The excitation regulation is used for generating harmonic waves, modifying sound, enhancing frequency dynamics of the sound, improving definition, brightness, volume, warm feeling and thickness feeling, the pressure limit regulation is used for performing normalized modification on the sound, enabling the sound to be more powerful and comfortable, the noise reduction regulation is used for removing noise and noise of the sound, and the delay regulation is used for improving loudness of direct sound. The equalization parameters include ultra-low sound, bass, mid-low sound, mid-high sound, high sound and ultra-high sound, and the equalization parameters are used for adjusting electric signals with different frequency components respectively so as to compensate the defects of a loudspeaker and a sound field and compensate and modify various sound sources.
Step S304, according to the content scene, determining the original sound effect parameters to be adjusted and the target parameter values in the original configuration parameter list.
Specifically, according to the content scene, the predefined sound effect parameters related to the content scene are determined from the predefined sound effect parameter list, and target parameter values corresponding to the predefined sound effect parameters are extracted. And comparing the predefined sound effect parameters with the original sound effect parameters in the original configuration parameter list to further determine the original sound effect parameters to be adjusted.
Wherein, the predefined sound effect parameters included in the predefined sound effect parameter list include: the sound frequency represents the number of times of completing periodic variation in unit time and is used for describing the amount of frequent periodic movement, the sound frequency represents the number of times of vibration of a sound source per second, and the frequency range of sound which can be heard by human ears, namely audible sound, is usually 20Hz to 20kHz, and the frequency is called audio frequency or audio frequency. The spectral representation represents the distribution pattern of the components of a time function in terms of amplitude or phase as a function of frequency, and since sound is composed of a combination of pure tones of different frequencies and different intensities, the analysis of the frequency content and intensity of sound emitted by a sound source is called spectral analysis. The intensity of the sound wave can be quantitatively described by sound pressure and sound pressure level, and the magnitude of the sound pressure can be used for representing the strength of the sound wave. Acoustic power refers to the acoustic energy of a sound source passing vertically through a specified area per unit time, representing the power radiated over the entire audible frequency range, or to the power radiated over some limited frequency range.
And simultaneously, target parameter values corresponding to the predefined sound effect parameters are stored in the predefined sound effect parameter list, and the associated predefined sound effect parameters are determined from the predefined sound effect parameter list based on the content scene. For example, based on the determined content scene, the predefined sound effect parameters associated therewith include sound pressure, sound intensity, and sound frequency, and after the associated predefined sound effect parameters are determined, the target parameter values corresponding to the predefined sound effect parameters are obtained from the predefined sound effect parameter list.
Further, after the predefined sound effect parameters are determined, the predefined sound effect parameters are compared with all original sound effect parameters in the original configuration parameter list, so that the original sound effect parameters which are inconsistent with the predefined sound effect parameters in the original configuration parameter list are determined, and the original sound effect parameters to be adjusted are determined. For example, the original sound-effect parameters include: the sound frequency, the sound frequency spectrum, the sound pressure and the sound intensity are included, the predefined sound effect parameters also include the sound frequency, the sound frequency spectrum, the sound pressure and the sound intensity, target parameter values of the predefined sound effect parameters are compared with original parameter values of corresponding original sound effect parameters respectively, and therefore the original sound effect parameters which are inconsistent with the predefined sound effect parameters are determined to be the original sound effect parameters to be adjusted.
And S306, adjusting the original sound effect parameter to be adjusted according to the target parameter value to generate the adjusted sound effect parameter.
Specifically, after the original sound effect value of the original sound effect parameter is obtained by obtaining the original sound effect value of the original sound effect parameter and comparing the original sound effect value of the original sound effect parameter with the corresponding target parameter value of the predefined sound effect parameter, the original parameter value of the original sound effect parameter to be adjusted is adjusted according to the target parameter value of the predefined sound effect parameter until the original parameter value of the original sound effect parameter to be adjusted is consistent with the target parameter value of the corresponding predefined sound effect parameter, and then the adjusted sound effect parameter is obtained.
Furthermore, through the adjustment of the original sound effect parameters, including the adjustment of sound frequency, sound spectrum, sound pressure, sound intensity, sound power and the like, the modification and adjustment of the components determining the sound quality, including tone, timbre, volume and timbre, can be realized, so as to achieve the sound effect more satisfying the content scene. For example, according to different content scenes, the original sound effect parameters to be adjusted can be subjected to equalization adjustment, the sound effect is softer and more suitable for music type programs by adding low or middle low sound components, and the sound is hotter and more suitable for sports type programs by adding middle high sound or high sound components.
And step S308, generating a target sound effect according with the content scene according to the adjusted sound effect parameters.
Specifically, according to the adjusted sound effect parameters including the modified parameter values of the sound effect parameters, the adjusted target sound effect which conforms to the content scene is generated.
In the above steps, the original sound effect parameter to be adjusted and the target parameter value in the original configuration parameter list are determined according to the content scene by extracting the original configuration parameter list corresponding to the original sound effect. And then adjusting the original sound effect parameters to be adjusted according to the target parameter values to generate adjusted sound effect parameters. According to the adjusted sound effect parameters, the target sound effect which accords with the content scene can be automatically generated, the manual adjustment of a user is not needed, the problem that the sound effect is poor due to the fact that the sound effect is poor in the manual adjustment of the user is avoided, the problem that repeated operation is needed is solved, and the sound effect adjustment efficiency is further improved.
In one embodiment, as shown in fig. 4, a sound effect adjusting method is provided, which specifically includes the following steps:
step S402, when the program switching instruction is detected, the original playing program is switched to the target playing program in response to the program switching instruction.
Specifically, when a user is detected to trigger a program switching instruction on a television product, the program switching instruction is responded, a target playing program corresponding to the program switching instruction is obtained, and an original playing program before the program switching instruction is triggered is switched into the target playing program.
Further, fig. 5 provides a schematic diagram of a program switching interface, referring to fig. 5, a program type played on a screen of a current television product 500 is a sports program 502, when a program switching instruction triggered by a user is detected, a target played program corresponding to the acquired program switching instruction is a video program 504, and the sports program 502 before the program switching instruction is triggered is switched to the video program 504 in response to the program switching instruction.
Step S404, collecting the screen content when the target playing program is played, and obtaining the playing time length of the target playing program.
Specifically, the screen content of the target playing program is collected in real time and stored to obtain a multi-frame screen image, and meanwhile, the playing time of the target playing program is counted.
Further, when the target playing program is a movie program, the screen content of the movie program is collected in real time, and the playing time of the movie program is counted.
Step S406, when the playing time of the target playing program exceeds the preset time domain, if the collection time reaches the preset time, obtaining a dynamic screen image with the preset time.
Specifically, when the target broadcast program is a video program, the broadcast time of the video program is compared with a preset time domain, and whether the broadcast time exceeds the preset time domain is determined. Wherein the time domain represents the continuity of the dynamically identified scene in the time dimension. For example, the automatic recognition scene is a football game in a sports program, but other television functions may be operated by a user midway, for example, switching to a video program, when the playing time of the video program exceeds a preset time domain, comparing the acquisition time for acquiring the screen image content with the preset time, and when the acquisition time reaches the preset time, generating a dynamic screen image with the preset time according to the acquired screen image content.

Further, when the duration of the process of watching the movie and television programs is short and does not reach the preset time domain, and the user continues to switch back to the sports program to watch the football match, the duration of the switching to the movie and television programs does not reach the preset time domain, and therefore the screen images of the movie and television programs do not need to be collected.
In the sound effect adjusting method, when a program switching instruction is detected, the original playing program is switched to the target playing program in response to the program switching instruction. By acquiring the screen content when the target playing program is played and acquiring the playing time of the target playing program, when the playing time of the target playing program exceeds a preset time domain, if the acquisition time reaches the preset time, a dynamic screen image with the preset time is obtained. The target playing program is judged to need to be subjected to sound effect adjustment when the time for continuously playing the switched program reaches the preset time domain, so that frequent sound effect switching and misoperation can be avoided, and the accuracy of sound effect adjustment is further improved.
