Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The sound effect adjusting method provided by the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 autonomously collects screen content to obtain multi-frame screen images. The content played by the screen is sent to the terminal 102 by the server 104 via a data communication connection. The terminal 102 generates a recognition result for the screen image by recognizing the content of the screen image, and further generates a predicted content scene list according to the recognition result. The terminal 102 matches the 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. Further, the terminal 102 dynamically adjusts the original sound effects based on the content scene, and generates target sound effects conforming to 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 as a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, an audio effect adjustment method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step S202, screen content is collected, and multi-frame 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 consisting of the image content being played by the screen.
Further, the terminal may be a television product, and when the user uses the television product, the television product may collect screen content corresponding to a program selected by the user in real time, and extract the screen content to obtain a multi-frame screen image. The television product can also collect the image content played by the screen in a preset extraction period to obtain multi-frame screen images.
Step S204, identifying the content of the screen image, and generating a predicted content scene list according to the identification result.
Specifically, as a television product of the terminal, a recognition result of the corresponding screen image is generated by recognizing the extracted multi-frame screen image content. Wherein, the content scene expressed by the extracted multi-frame screen image can be dynamically identified by utilizing AI artificial intelligence technology, wherein, the content scene can comprise that the user plays music, the user watches film and television programs, the user watches sports programs, the user watches news programs, the user plays games, and the like.
The method comprises the steps of carrying out image content recognition on a plurality of acquired screen images locally, sending the images to a cloud server through a network to carry out more accurate content recognition, and determining a current content scene by applying a weighted big data matching algorithm and rules according to the content of the current image and the content recognized in the last period of time. Wherein the image of the near time refers to the recognition of other images already cached in front of the frame image, namely, continuous reference of the most recently used content.
Further, the extracted multi-frame screen image is a continuous dynamic image with preset duration. Compared with the traditional static image recognition operation which focuses on the instant state, the accuracy degree of the generated recognition result can be further improved by extracting continuous multi-frame screen images and then performing content recognition operation. And analyzing the generated identification result to obtain a predicted content scene list, namely the content scene to which the content played by the current screen possibly belongs.
In one embodiment, taking the example that a user plays music and views pictures at the same time, namely, the user searches pictures on a television product to view, and the background opens music playing software at the same time to play music, the searched pictures are still scenery photos or photo figures. When the current screen content is collected and identified, the identification result is static landscape or character photo, and the obtained predicted content scene list can comprise different content scenes of the user playing music and the like when the user watches the video program, and the picture is in a static state and can also be used as a protection interface of a music application program.
Step S206, acquiring system operation information, and matching the 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 playing state information and interface information, and the current playing state of the screen can be determined according to the playing state information, wherein the current playing state includes different states such as playing video, playing audio and displaying pictures. The type of the application program in the current running of the television product can be determined according to the interface information, wherein the type of the application program comprises a video 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 whether a video application program, a game application program or a music application program is running in combination with the currently running application program, determining content scenes matched with system running information, namely playing state information and interface information, from a predicted content scene list.
In one embodiment, taking the example that the user plays music and views the picture at the same time, by acquiring system operation information including play state information and interface information, since the user is viewing the picture, the current play state can be determined to be the display picture, and when detecting that the currently running application program in the system is a music application program, the user can be determined to play music. Because the picture is viewed without setting corresponding music sound effects, the content scene needing to be subjected to sound effect adjustment can be further determined to be the music played by the user.
In another embodiment, taking the example that the user plays a game program, that is, the application program opened by the user is a video application program, the program selected to be played is a game program. The method comprises the steps of acquiring screen content to obtain multi-frame screen images related to games, identifying the multi-frame screen images to obtain identification results, and obtaining a predicted content scene list according to the identification results, wherein the predicted content scene list comprises video programs watched by a user or games played by the user. By acquiring system operation information including play state information and interface information, since a user plays a game program and opens a video application program, the current play state is determined to be a play video, and the type of the currently operated application program is a video application program. And judging by combining the identification result of the image content and the system operation information, wherein the more accurate content scene matched from the predicted content scene list is that the user is watching the film and television program.
Step S208, based on the content scene, dynamically adjusting the original sound effect to generate a target sound effect conforming to the content scene.
Specifically, before the sound effect adjustment operation is performed, the sound effect applied by the television product is a preset original sound effect. The original sound effect is the conventional sound effect of the television product, and can be used in different content scenes, but the sound effect cannot meet all content scenes, and cannot reach the optimal expected sound effect of the user in different content scenes. Dynamic adjustment of the original sound effects based on the content scene is therefore required to meet the best desired sound effects in the current content scene.
Further, by extracting an original configuration parameter list corresponding to the original sound effect, determining target parameter values of each sound effect parameter according to the determined content scene, and determining the original sound effect parameter to be adjusted from the original configuration parameter list according to the content scene. And then the original sound effect parameters to be adjusted are adjusted according to the target parameter values, adjusted sound effect parameters are generated, and target sound effects which accord with the content scene are generated according to the adjusted sound effect parameters.
In the sound effect adjusting method, the screen content is collected to obtain multi-frame screen images, the content of the screen images is identified, and a predicted content scene list is generated according to the identification result. By acquiring the system operation information, comprehensive judgment is carried out according to the system operation information, more accurate content scenes corresponding to screen content are matched from the predicted content scene list, and then the original sound effect is dynamically adjusted based on the content scenes, so that the target sound effect which accords with the content scenes is generated. The problem of repeated operation caused by poor manual sound effect adjustment is avoided without manual adjustment of a user, and the sound effect adjustment efficiency is further improved.
In one 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, and generating the target sound effect conforming to the content scene specifically includes the following steps corresponding to S302 to S308:
Step S302, extracting an original configuration parameter list corresponding to the original sound effect.
Specifically, before the sound effect adjustment operation is performed, the sound effect applied by the television product is a preset original sound effect, original configuration parameters corresponding to the original sound effect and corresponding parameter values are stored in a local database of the television product in advance, and when the 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 database, wherein the original configuration parameters and the original parameter values corresponding to the configuration parameters are included.
The components determining the sound quality include tone, timbre, volume and sound quality, wherein the tone is determined by the frequency spectrum of sound waves, and represents the level of sound frequency and is related to the vibration times of a sound source per second. A low pitch means a low vibration frequency, a deep sound, a high pitch means a high vibration frequency, and a sharp sound. The volume is determined by the amplitude of the sound wave, which refers to the intensity or loudness of the sound, and the intensity of the marked sound is related to the magnitude of the vibration amplitude of the sound source, so that the sound cannot be heard, and the sound cannot be heard, so that the sound cannot be accepted by human ears.
The musical sound is determined by the waveform envelope of the sound wave, the musical sound represents the sound used in the music, the harmonic composition and the waveform envelope of the sound wave, including the starting and ending transients of the musical sound, determine the characteristics of the musical sound, namely the musical sound. The growth and decay process of the sound can determine the quality of the sound, and meanwhile, the difference exists between the corresponding sound spectrums of the quality, and the difference appears in the intensity distribution of spectral lines. The tone is determined by the frequency spectrum of sound waves, and refers to the color and characteristics of sound, and the tone can be used as a sign of a single frequency by correlating with the frequency spectrum of sound source vibration, so that the tone can be expressed as a representation of a composite frequency composed of multiple frequencies. The fundamental frequency component in the sound spectrum forms fundamental tone of sound, the tone can be determined by the fundamental frequency, other components in the sound spectrum are overtones, the overtones are multiplied by the fundamental tone, and the tone is determined by the structure of the overtones.
Further, excitation adjustment, voltage limit adjustment, noise reduction adjustment, delay adjustment, and equalization adjustment may be performed for each configuration parameter. The excitation adjusting device comprises a sound adjusting device, a pressure limiting adjusting device, a sound adjusting device and a sound adjusting device, wherein the excitation adjusting device is used for generating harmonic waves, modifying the sound, enhancing frequency dynamic of the sound, improving definition, brightness, volume, warmth and heaviness, the pressure limiting adjusting device is used for normalizing and modifying the sound, enabling the sound to be more powerful and comfortable, the noise reducing adjusting device is used for removing noise and noise of the sound, and the delay adjusting device is used for improving the loudness of direct sound. The equalization parameters include subwoofer, bass, midrange, treble, and the equalization parameters are used to respectively adjust the electric signals of different frequency components to compensate defects of the loudspeaker and the sound field, and to 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, a predefined sound effect parameter associated with the content scene is determined from a predefined sound effect parameter list, and a target parameter value corresponding to the predefined sound effect parameter is extracted. And comparing the predefined sound effect parameters with the original sound effect parameters of 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: sound frequency, sound spectrum, sound pressure, sound intensity, sound power and the like, wherein the frequency represents the number of times of completing periodic change in unit time and is used for describing the frequency degree of periodic movement, the sound frequency represents the number of times of vibration of a sound source per second, and the frequency range of audible sound which can be heard by human ears is usually 20 Hz-20 kHz, and the frequency is called audio frequency or audio frequency. Spectral representation represents the components of a time function as a distribution pattern of frequency functions in terms of amplitude or phase, and since sound is composed of a number 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 sound pressure can be used for representing the intensity of the sound wave. Acoustic power refers to the acoustic energy of a sound source passing vertically through a designated 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 meanwhile, target parameter values corresponding to all the predefined sound effect parameters are also 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 with the determined content scene include sound pressure, sound intensity and sound frequency, and after the associated predefined sound effect parameters are determined, 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 parameter is determined, the predefined sound effect parameter is compared with each original sound effect parameter in the original configuration parameter list, so that the original sound effect parameter inconsistent with the predefined sound effect parameter in the original configuration parameter list is determined, and the original sound effect parameter to be adjusted is determined. For example, the original sound effect parameters include: the predefined sound effect parameters also comprise sound frequency, sound frequency spectrum, sound pressure and sound intensity, and the target parameter values of the predefined sound effect parameters are respectively compared with the original parameter values of the corresponding original sound effect parameters, so that the original sound effect parameters inconsistent with the predefined sound effect parameters are determined as the original sound effect parameters to be adjusted.
Step S306, the original sound effect parameters to be adjusted are adjusted according to the target parameter values, and adjusted sound effect parameters are generated.
Specifically, the original sound effect value of the original sound effect parameter is obtained, the original sound effect value of the original sound effect parameter is respectively compared with the corresponding target parameter value of the predefined sound effect parameter, after the original sound effect parameter to be adjusted is obtained, 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 corresponding target parameter value of the predefined sound effect parameter, and then the adjusted sound effect parameter is obtained.
Further, by adjusting the original sound effect parameters, including adjusting the sound frequency, the sound spectrum, the sound pressure, the sound intensity, the sound power, and the like, the modification and adjustment of the components determining the sound quality, including the tone, the timbre, the volume, and the sound quality, can be realized so as to achieve the sound effect more meeting the content scene. For example, according to different content scenes, the original sound effect parameters to be adjusted can be adjusted in an equalizing manner, the sound effect can be softer by adding bass or mid-bass components, the sound effect is more suitable for music programs, and the sound can be more intense by adding mid-treble or treble components, so that the sound is more suitable for sports programs.
Step S308, generating target sound effects which accord 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 conforming to the content scene is generated.
In the above steps, the original configuration parameter list corresponding to the original sound effect is extracted, and 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. And then the original sound effect parameters to be adjusted are adjusted according to the target parameter values, and the adjusted sound effect parameters are generated. According to the adjusted sound effect parameters, the target sound effect which accords with the content scene can be automatically generated, manual adjustment of a user is not needed, the problem that repeated operation is needed due to the fact that the user manually adjusts the condition that the sound effect is poor is avoided, and the sound effect adjusting efficiency is further improved.
In one embodiment, as shown in fig. 4, there is provided an audio effect adjusting method, 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 detecting that a user triggers a program switching instruction on a television product, responding to the program switching instruction, acquiring a target playing program corresponding to the program switching instruction, and switching an original playing program before triggering the program switching instruction into the target playing program.
Further, fig. 5 provides a schematic view of a program switching interface, referring to fig. 5, the type of a program played on the screen of the current television product 500 is a sports program 502, when a program switching instruction triggered by a user is detected, the obtained target playing program corresponding to the program switching instruction is a movie program 504, and the program switching instruction is responded, and the sports program 502 before the program switching instruction is triggered is switched to the movie program 504.
Step S404, screen content when the target playing program is played is collected, and playing time length of the target playing program is obtained.
Specifically, screen content when the target playing program is played is collected in real time and stored, a multi-frame screen image is obtained, and meanwhile, the playing time of the target playing program is counted.
Further, when the target playing program is a video program, screen content when the video program is played is collected in real time, and meanwhile playing time of the video program is counted.
Step S406, when the playing time of the target playing program exceeds the preset time domain, if the collecting time reaches the preset time, obtaining the dynamic screen image of the preset time.
Specifically, when the target playing program is a video program, comparing the playing time length of the video program with a preset time domain, and judging whether the playing time length exceeds the preset time domain. Wherein the time domain represents the continuity of the dynamically identified scene in the time dimension. For example, the scene is automatically identified as a football match in a sports program, but other television functions may be operated by a user in the middle, such as switching to a movie program, comparing the acquired time length of acquiring the screen image content with the preset time length when the playing time length of the movie program exceeds the preset time domain, and generating a dynamic screen image with the preset time length according to the acquired screen image content when the acquired time length reaches the preset time length.
In this embodiment, the preset time domain may be set to 20S, the preset duration may be set to 30S, after the playing duration of the movie program exceeds 20S, the collection duration may be counted, when the collection duration reaches 30S, and when the collection duration reaches the preset time size, a dynamic screen image with a length of 30S may be generated according to the content of the screen image collected by collection.
Further, when the duration of the process of watching the video program is shorter and does not reach the preset time domain, and the user switches back to the sports program to watch the football match, the screen image of playing the video program is not required to be acquired because the duration of switching to the video program does not reach the preset time domain.
In the above sound effect adjusting method, when the program switching instruction is detected, the original broadcast program is switched to the target broadcast program in response to the program switching instruction. Acquiring screen content when a target broadcast program is broadcast, acquiring the broadcast time length of the target broadcast program, and acquiring a dynamic screen image of the preset time length if the acquired time length reaches the preset time length when the broadcast time length of the target broadcast program exceeds the preset time domain. By judging that the target playing program needs to be subjected to sound effect adjustment when the time of continuously playing the switched program reaches a preset time domain, frequent sound effect switching and misoperation can be avoided, and the accuracy of sound effect adjustment is further improved.
