Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to methods, apparatus, storage media and electronic devices for determining shooting modes. Background Technology

[0002] With the increasing development of image applications, captured images can be directly processed in image processing scenarios, and the processed images can be presented to users, thereby significantly improving user experience and enhancing image expressiveness. When capturing images in image processing scenarios, the choice of shooting mode has a significant impact on the image processing effect. High-definition shooting mode offers strong image processing performance, but it leads to greater resource consumption and may also cause some performance loss. Therefore, how to capture as many high-definition images as possible to improve image expressiveness while accurately controlling resource consumption and performance loss is an urgent problem to be solved. Summary of the Invention

[0003] This disclosure provides a shooting mode determination method, apparatus, storage medium, and electronic device to at least solve at least one problem in the related art. The technical solution of this disclosure is as follows:

[0004] According to a first aspect of the present disclosure, a shooting mode determination method is provided, comprising:

[0005] Multiple shooting performance records are acquired, each of which includes shooting conditions, shooting mode, and shooting performance parameters. The shooting performance parameters indicate the shooting performance under the corresponding shooting conditions and using the corresponding shooting mode.

[0006] Based on the multiple shooting performance records, a shooting performance change parameter is determined for each shooting condition. The shooting performance change parameter indicates the amount of change in shooting performance when shooting in the first shooting mode under the shooting condition relative to shooting performance when shooting in the second shooting mode under the shooting condition. The second shooting mode is the shooting mode used when the first shooting mode is not used.

[0065] This disclosure embodiment can acquire multiple shooting performance records, thereby clarifying the shooting performance parameters corresponding to each shooting mode under each shooting condition, and thus determining the shooting performance corresponding to each shooting mode under each shooting condition. Based on the shooting performance records, the shooting performance variation parameters corresponding to each shooting condition can be determined, thereby determining the performance loss generated by the high-definition shooting mode (first shooting mode) under each shooting condition. Based on the performance loss, the shooting performance cost generated by using the high-definition shooting mode under each shooting condition is determined. By controlling this shooting performance cost, with maximizing the high-definition shooting mode as the optimization objective, it is possible to determine which shooting conditions use the high-definition shooting mode and which do not. This shooting mode determination method can achieve precise and scientific shooting mode selection, maximizing the overall coverage of the high-definition shooting mode in the global dimension formed by various shooting conditions, and precisely controlling the shooting performance cost.

[0066] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. Attached Figure Description

[0078] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0079] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0080] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for display, data used for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0081] For image applications, the sharpness of the image captured in the image processing scenario has a significant impact on the final image processing effect. Taking image effects processing as an example, this scenario allows for the configuration of magical expressions or the generation of various special effects from the captured image. For instance, it can intelligently generate 2D and 3D magical expressions, enhance image beautification, portrait retouching, and generate various image elements based on artificial intelligence. This results in highly expressive image processing results and is crucial for enhancing the user experience in image applications. The higher the sharpness of the captured image, the stronger the expressiveness of the resulting image processing.

[0082] However, high-definition shooting mode often means consuming more hardware resources and sacrificing some performance. For example, it may lead to a degradation in QoS / QoE metrics. QoS stands for "Quality of Service," referring to service quality indicators. QoS metrics refer to client-side service metrics when a user is shooting video, such as frame rate, crash rate, and stuttering rate. QoE stands for "Quality of Experience," referring to quantifiable experience metrics, including the probability of triggering at least one preset action, such as click-through rate and upload rate.

[0083] To control performance loss, related technologies rely on human experience to specify whether high-definition shooting mode can be used under each shooting condition. However, this approach is not scientifically reliable enough, relies too heavily on human experience, and cannot achieve fine-grained control of performance loss, nor can it maximize the coverage of high-definition shooting mode globally.

[0084] To precisely control the fine-grained degradation loss of key QoS / QoE indicators and maximize the global coverage of high-definition shooting modes while keeping the degree of degradation controllable, this disclosure provides a shooting mode determination scheme. This method can accurately control the performance loss (performance cost) of each important QoS / QoE indicator, and, while accurately controlling the performance loss of each important QoS / QoE indicator, ensures the maximization of the coverage of high-definition shooting modes in the set of shooting conditions formed by various shooting conditions. This disclosure does not rely on human experience and is more scientific and reliable.

[0085] Figure 1This is a flowchart illustrating a shooting mode determination method according to an exemplary embodiment. The shooting mode determination method can be applied to an electronic device, which can be implemented independently by a server or a terminal, or jointly by a terminal and a server. The terminal can be, but is not limited to, physical devices such as smartphones, tablets, laptops, desktop computers, smart speakers, smart wearable devices, digital assistants, augmented reality devices, and virtual reality devices, and can also include software such as applications running on the physical device. The server can be, but is not limited to, a standalone server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud storage, network services, cloud communication, middleware services, domain name services, security services, and big data and artificial intelligence platforms, etc. (Refer to...) Figure 1 As shown, the method includes the following steps.

[0086] In step S101, multiple shooting performance records are acquired. Each of the above shooting performance records includes shooting conditions, shooting mode, and shooting performance parameters. The shooting performance parameters indicate the shooting performance under the corresponding shooting conditions and using the corresponding shooting mode.

[0087] For each shooting condition, a first shooting mode can be used to take several shots under that condition. Based on the shooting performance data obtained during each shot, a statistical result of the shooting performance data corresponding to the first shooting mode under that shooting condition is obtained, i.e., the shooting performance parameters corresponding to shooting with the first shooting mode under that shooting condition are obtained, thus generating a shooting performance record. This shooting performance record includes the shooting condition, the first shooting mode, and the corresponding shooting performance parameters. Furthermore, a second shooting mode can also be used to take several shots under that shooting condition. Based on the shooting performance data obtained during each shot, a statistical result of the shooting performance data corresponding to the second shooting mode under that shooting condition is obtained, i.e., the shooting performance parameters corresponding to shooting with the second shooting mode under that shooting condition are obtained, thus generating a shooting performance record. This shooting performance record includes the shooting condition, the second shooting mode, and the corresponding shooting performance parameters.

[0088] In this disclosure, the first shooting mode can be a high-definition shooting mode, specifically, a 1080P shooting mode. In 1080P shooting mode, the captured image has a resolution of 1920×1080 pixels, enabling the capture of more details. The second shooting mode can be any shooting mode other than the first shooting mode; that is, the second shooting mode is a non-high-definition shooting mode.

[0089] This disclosure does not limit the method of obtaining shooting performance records. In an exemplary embodiment, shooting performance data generated by the client when shooting images in an image processing scenario, such as an image effects processing scenario, can be recorded, such as single frame rate, number of stutters, number of crashes, number of uploaded works, etc., to obtain shooting records. Each shooting record may include shooting conditions, shooting mode (first shooting mode or second shooting mode), and the generated shooting performance data. Then, shooting records are aggregated with shooting conditions and shooting mode as the primary key. For example, shooting records with shooting condition 1 and first shooting mode are aggregated together. Based on the shooting performance data in these aggregated shooting records, the shooting performance parameters corresponding to shooting condition 1 and first shooting mode are statistically obtained, thereby generating a shooting performance record.

[0090] In some implementations, shooting modes can be randomly assigned to clients, so that some clients use the first shooting mode and others use the second shooting mode, thereby enriching the content of the aforementioned shooting records and enabling the acquisition of shooting records generated under various shooting modes and conditions, so as to obtain high-quality shooting performance records.

[0091] For example, if a total of 10 shooting records are obtained under shooting condition 1 and the first shooting mode, and these 10 shooting records include shooting performance data such as single frame rate, number of stutters, number of crashes, and number of uploaded works, then statistical calculations can be performed on these shooting performance data to obtain shooting performance parameters such as frame rate (average frame rate), stutter rate, crash rate, and uploaded works rate under shooting condition 1 and the first shooting mode, and generate corresponding shooting performance records.

[0092] In step S102, based on the above multiple shooting performance records, a shooting performance change parameter corresponding to each of the above shooting conditions is determined. The shooting performance change parameter indicates the amount of change in shooting performance when shooting using the first shooting mode under the above shooting conditions relative to shooting performance when shooting using the second shooting mode under the above shooting conditions. The second shooting mode is the shooting mode used when the first shooting mode is not used.

[0093] In this disclosure, the aforementioned shooting performance variation parameters include at least one of the following performance variation indicators: service quality variation indicator and experience quantification variation indicator. The service quality variation indicator includes at least one of the following: frame rate variation, crash rate variation, and stuttering rate variation. The experience quantification variation indicator includes at least one preset operation trigger probability variation. Shooting performance parameters include service quality indicators and / or experience quantification indicators, and the shooting performance parameter variation parameters indicate the differences in shooting performance parameters between different shooting modes under the same shooting conditions. This disclosure provides scalable support for precise performance loss control of fine-grained shooting performance indicators, and, under the premise of fine-grained performance loss control, achieves maximum coverage of global high-definition shooting modes.

[0094] Taking shooting condition 1 as an example, among the aforementioned multiple shooting performance records, there is a shooting performance record Note1 that uses shooting condition 1 and the first shooting mode, and there is also a shooting performance record Note2 that uses shooting condition 1 and the second shooting mode. The change in frame rate in Note1 relative to the frame rate in Note2 is the change in frame rate corresponding to shooting condition 1; the change in stuttering rate in Note1 relative to the stuttering rate in Note2 is the change in stuttering rate corresponding to shooting condition 1, and so on for the shooting performance change parameters corresponding to other shooting conditions.

[0095] This disclosure does not limit the shooting conditions, which may include several sub-conditions. Therefore, this disclosure supports scalable shooting mode decisions under multiple conditions. For example, the shooting conditions include a first condition and a second condition. The first condition indicates the model of the electronic device used during shooting, and the second condition indicates the image processing scheme used during shooting. Continuing with the previous example, shooting condition 1 = electronic device model A and image processing scheme B, that is, one electronic device model paired with one image processing scheme uniquely determines one shooting condition. Therefore, this disclosure can select the most suitable shooting mode for any electronic device model and any image processing scheme, and achieve maximum coverage of global high-definition shooting modes under the premise of fine-grained performance loss control.

[0096] In step S103, based on the shooting performance change parameters corresponding to each of the above shooting conditions and the mode control parameters corresponding to each of the above shooting conditions, the shooting performance cost corresponding to the first shooting mode is determined, and the mode control parameters indicate whether the first shooting mode is activated under the corresponding shooting conditions.

[0097] In this disclosure, the shooting performance cost corresponding to the first shooting mode includes the performance cost corresponding to each of the above-mentioned performance change indicators. The determination of the shooting performance cost corresponding to the first shooting mode based on the shooting performance change parameters corresponding to each of the above-mentioned shooting conditions and the mode control parameters corresponding to each of the above-mentioned shooting conditions includes: for any performance change indicator, determining the performance cost corresponding to the performance change indicator based on the performance change indicators corresponding to each of the above-mentioned shooting conditions and the mode control parameters corresponding to each of the above-mentioned shooting conditions.

[0098] This disclosure allows you to calculate the corresponding performance cost, or performance loss, for each performance change metric. Please refer to [link / reference]. Figure 2 The diagram illustrates a flowchart of the performance cost calculation method of this disclosure. The performance cost corresponding to the aforementioned performance change indicators is determined based on the performance change indicators corresponding to each of the aforementioned shooting conditions, and the mode control parameters corresponding to each of the aforementioned shooting conditions, including:

[0099] In step S201, for each of the above shooting conditions, the unit shooting performance cost corresponding to the above shooting conditions is determined based on the product of the above performance change index corresponding to the above shooting conditions and the mode control parameter corresponding to the above shooting conditions.

[0100] For example, b i,j,t Let t represent the performance change index corresponding to the shooting conditions determined for electronic device model i and image processing scheme j. If there are 3 performance change indices, t can take the values ​​1, 2, and 3 respectively. i,j This indicates the mode control parameter corresponding to this shooting condition, x i,j A value of 0 indicates that the first shooting mode is not used under these shooting conditions. i,j A value of 1 indicates that the first shooting mode is used under these shooting conditions. i,j,t x i,j This indicates the unit shooting performance cost corresponding to this performance change index under the shooting conditions.

[0101] In step S202, the unit shooting performance costs corresponding to the above performance change indicators under each of the above shooting conditions are summed to obtain the performance costs corresponding to the above performance change indicators.

[0102] For example, one can use b i,j,t x i,jThe performance cost corresponding to the performance change index numbered t is calculated, where N represents the total number of electronic device models and M represents the total number of image processing schemes. This disclosure defines a method for calculating the performance cost corresponding to any performance change index, thereby enabling precise control over the performance cost generated by fine-grained performance change indexes and improving the accuracy of performance loss control.

[0103] In step S104, when the shooting performance cost satisfies the preset cost constraint, the mode control parameters corresponding to each of the above shooting conditions are determined by maximizing the coverage of the first shooting mode in the set of shooting conditions formed by each of the above shooting conditions.

[0104] This disclosure embodiment can acquire multiple shooting performance records, thereby clarifying the shooting performance parameters corresponding to each shooting mode under each shooting condition, and thus determining the shooting performance corresponding to each shooting mode under each shooting condition. Based on the shooting performance records, the shooting performance variation parameters corresponding to each shooting condition can be determined, thereby determining the performance loss generated by the high-definition shooting mode (first shooting mode) under each shooting condition. Based on the performance loss, the shooting performance cost generated by using the high-definition shooting mode under each shooting condition is determined. By controlling this shooting performance cost, with maximizing the high-definition shooting mode as the optimization objective, it is possible to determine which shooting conditions use the high-definition shooting mode and which do not. This shooting mode determination method can achieve precise and scientific shooting mode selection, maximizing the overall coverage of the high-definition shooting mode in the global dimension formed by various shooting conditions, and precisely controlling the shooting performance cost.

[0105] In this disclosure, the aforementioned preset cost constraint includes sub-constraints corresponding to each of the aforementioned performance costs. When the aforementioned shooting performance costs satisfy the preset cost constraint, determining the mode control parameters corresponding to each of the aforementioned shooting conditions by maximizing the coverage of the first shooting mode in the set of shooting conditions formed by the aforementioned shooting conditions includes:

[0106] When the performance cost corresponding to each of the above-mentioned performance change indicators satisfies the sub-constraints corresponding to the above-mentioned performance cost, the mode control parameters corresponding to each of the above-mentioned shooting conditions are determined by maximizing the coverage of the first shooting mode in the set of shooting conditions formed by each of the above-mentioned shooting conditions.

[0107] For example, if the shooting performance change parameter includes three performance change indicators, then a sub-constraint is set for each performance change indicator, for a total of three sub-constraints. That is, the preset cost constraint includes three sub-constraints. For example, suppose the preset cost constraint can be described as a frame rate decrease of no less than 0.1%, a stuttering rate increase of no more than 0.2%, and a recording upload rate decrease of no less than 0 (the number of uploaded works cannot decrease); then the preset cost constraint can be decomposed into three sub-constraints, namely, constraint B1 corresponding to the frame rate change, which is used to constrain the frame rate decrease of no less than 0.1%; constraint B2 corresponding to the stuttering rate change, which is used to constrain the stuttering rate increase of no more than 0.2%; and constraint B3 corresponding to the upload rate change, which is used to constrain the recording upload rate decrease of no less than 0. Then the aforementioned "the performance cost corresponding to each of the above performance change indicators satisfies the sub-constraints corresponding to the above performance costs" can be expressed as the following formula (I):

[0108]

[0109]

[0110] Formula (1)

[0111] In Formula (I), b i,j,1 b i,j,2 b i,j,3 These correspond to changes in frame rate, stuttering, and upload rate, respectively.

[0112] Please refer to Figure 3 This illustrates a flowchart of a method for determining the coverage of a first shooting mode within a set of shooting conditions formed by the aforementioned shooting conditions. Before determining the mode control parameters corresponding to each of the aforementioned shooting conditions by maximizing the coverage of the first shooting mode within the set of shooting conditions formed by the aforementioned shooting conditions, the method further includes:

[0113] In step S301, based on the above multiple shooting performance records, the first number of shots corresponding to the first shooting mode under each of the above shooting conditions and the second number of shots corresponding to the second shooting mode under each of the above shooting conditions are determined.

[0114] Taking the previous example, under shooting condition 1, each shot taken using the first shooting mode creates a shooting record. Therefore, if there are T shooting records formed under shooting condition 1 using the first shooting mode, then the first shooting count is T. The method for obtaining the second shooting count is based on the same inventive concept and will not be elaborated here. For example, p can be used in this disclosure. i,j The first number of shots under the shooting conditions determined by the electronic device model number i and the image processing scheme number j can be represented by q. i,jThis indicates the second number of shots under the shooting conditions determined by the electronic device model number i and the image processing scheme number j.

[0115] In step S302, the first number of shots corresponding to each of the above shooting conditions and the second number of shots corresponding to each of the above shooting conditions are summed to obtain the total number of shots.

[0116] For example, based on formula The total number of shots (cnt) can then be calculated.

[0117] In step S303, for each of the above shooting conditions, the number of times the first shooting mode covers the unit under the above shooting conditions is determined based on the product of the mode control parameters corresponding to the above shooting conditions and the number of first shots corresponding to the above shooting conditions; and the unit coverage rate of the first shooting mode under the above shooting conditions is determined based on the ratio of the number of unit coverages to the total number of shots.

[0118] For example, based on formula The unit coverage rate of the first shooting mode can be calculated under the shooting conditions determined by the electronic device model number i and the image processing scheme number j.

[0119] In step S304, the coverage rate of the first shooting mode in the shooting condition set formed by the shooting conditions is determined based on the sum of the unit coverage rates corresponding to each of the above shooting conditions for the first shooting mode.

[0120] For example, based on The coverage rate of the first shooting mode in the set of shooting conditions formed by the aforementioned shooting conditions can then be obtained. This disclosure provides a specific calculation scheme for the coverage rate of the first shooting mode in the set of shooting conditions formed by the aforementioned shooting conditions, thereby expressing both the constraints and the coverage rate of the first shooting mode in the set of shooting conditions using formulas. Therefore, it supports obtaining the mode control parameters under each shooting condition by solving formulas, thus ensuring the accuracy of the mode control parameters. Furthermore, the solution process is simple and resource-efficient.

[0121] The process of maximizing the coverage of the first shooting mode in the set of shooting conditions formed by the aforementioned shooting conditions can be expressed as formula (II).

[0122]

[0123] Formula (II)

[0124] This disclosure, under the constraint of formula (I), makes formula (II) reach its maximum value, thereby determining x. i,j xi,j This refers to the mode control parameters under the shooting conditions determined by the electronic device model number i and the image processing scheme number j.

[0125] This disclosure proposes that, for each electronic device model and each image processing scheme, querying the corresponding mode control parameters using traditional query methods would be extremely time-consuming. For example, after a client enters an image processing scene, a list of effects can be pushed to the client, indicating multiple image processing effects available. For instance, if the effect list includes 10 effects, the user can select any effect to capture an image in the corresponding image processing scene. The client then needs to know the corresponding mode control parameters, i.e., whether 1080P recording is required. Using traditional query methods, querying the server for the corresponding mode control parameters for each effect would be extremely time-consuming. Therefore, this disclosure provides a fast mode control parameter query scheme for the server.

[0126] Please refer to Figure 4 The diagram illustrates a flowchart of the mode control parameter query method of this disclosure. The method further includes:

[0127] In step S401, a target two-dimensional matrix is ​​determined based on the mode control parameters corresponding to each of the above shooting conditions. The rows of the target two-dimensional matrix are used to indicate the first condition, the columns of the target two-dimensional matrix are used to indicate the second condition, and the elements of the target two-dimensional matrix are used to indicate the mode control parameters under the shooting conditions formed by the corresponding first condition and the corresponding second condition.

[0128] The target two-dimensional matrix in this disclosure can be understood as a bitmap index built based on bitmap concepts, serving as a data indexing technique to accelerate the retrieval of mode control parameters. Please refer to [reference needed]. Figure 5 This illustrates a bitmap index diagram in this disclosure. Figure 5Each row in the bitmap index corresponds to an electronic device model, and each column corresponds to an effect, or in other words, an image processing scheme. The unique row and column numbers define unique two-dimensional matrix elements that represent the mode control parameters under the query conditions determined by the corresponding electronic device model and effect. During a query, given several rows and columns to be queried (e.g., several electronic device models and corresponding image processing schemes for several effects), the corresponding mode control parameters can be directly retrieved from the bitmap index in one query. Compared to related technologies where only one request can be generated for each electronic device model and effect, and multiple requests can only be sent for multiple electronic device models and multiple effects, with each request only able to query the mode control parameters for a single electronic device model and a single effect, the bitmap index-based mode control parameter query method proposed in this disclosure significantly improves query efficiency and can meet the needs of real-time queries.

[0129] In step S402, a parameter acquisition request sent by the client is received, which includes the target shooting conditions.

[0130] For example, the target shooting conditions mentioned above include a first target condition and multiple second target conditions. For instance, if the client's electronic device model is Model 1, and the associated image processing scheme, or the associated special effect, is an effect labeled 0-9, then the first target condition is "Model 1", and the 10 second target conditions correspond to labels 0-9 respectively.

[0131] In step S403, the target mode control parameters corresponding to the target shooting conditions are queried based on the above target two-dimensional matrix, and the above target mode control parameters are returned to the above client.

[0132] Please refer to Figure 6 The diagram illustrates a flowchart of the method for determining target mode control parameters disclosed herein. The above-mentioned method of querying the target mode control parameters corresponding to the target shooting conditions based on the above-mentioned two-dimensional target matrix includes:

[0133] In step S601, the target row is determined in the target two-dimensional matrix based on the first target condition.

[0134] Following the previous example, if the row corresponding to "Model 1" is in Figure 5 If the first line is in the middle, then the target line is the first line.

[0135] In step S602, the target column corresponding to each of the above-mentioned target second conditions is determined.

[0136] Following the previous example, the 10 target second conditions correspond to labels 0-9 respectively. When the label of the effect is the same as the label of the column, the columns labeled 0-9 are all target columns.

[0137] In step S603, the target mode control parameters corresponding to the target row and each of the target columns are determined.

[0138] Following the previous example, the values ​​of the elements in the first row corresponding to the columns marked 0-9 all belong to the target mode control parameters. If the value of the element in the first row corresponding to the columns marked 0-9 is "1, 1, 1, 1, 1, 0, 0, 0, 0", then the state of the first shooting mode corresponding to the special effects 0-9 is "On, On, On, On, On, On, Off, Off, Off, Off, Off, Off, Off".

[0139] Please refer to Figure 7 The diagram illustrates the architecture of the shooting mode determination method disclosed herein. At regular intervals, step S101 can be initiated to obtain multiple shooting performance records, thereby determining the mode control parameters corresponding to each shooting condition, and updating the bitmap index based on these mode control parameters. When the client requests to obtain the mode control parameters, a list of effects adapted to the client can be determined. Each effect in the effect list corresponds to an image processing scheme. Based on the client's electronic device model and the effect list, the target mode control parameters corresponding to each effect in the effect list can be determined, and the effect list and each mode control parameter are fed back to the client. The client can present the effect list to the user, and when any effect is triggered, the shooting mode is determined based on the mode control parameters corresponding to that effect, thereby supporting image capture in that shooting mode. The captured image is then applied to the corresponding effect.
