[0030] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. generally belong to the same category, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0032] Next, in conjunction with the accompanying drawings, the shooting method, shooting device, electronic device, and readable storage medium provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0033] As Figure 1 shown, in the embodiment of the present application, a shooting method is proposed, including:

[0034] Step 102, when the shooting preview interface is displayed, obtain first parameter information corresponding to a first image area in the shooting preview interface, where the first parameter information includes first depth information and first ambient brightness information.

[0035] The ambient brightness information can reflect the brightness and darkness of the environment where the captured image is located, and the depth information can be obtained to perform three-dimensional depth detection on the captured object.

[0036] In a possible application, a TOF (Time of Flight) sensor can be used to obtain depth information of a subject.

[0037] Step 104: Determine a first brightness influence coefficient of a first image area according to the first depth information and the first ambient brightness information;

[0038] Step 106: Determine a first exposure parameter according to the first brightness influence coefficient;

[0039] After obtaining the first depth information and the first ambient brightness information of the first image area, with reference to the first depth information and the first ambient brightness information, the first brightness influence coefficient of the first image area can be determined. Through the first brightness influence coefficient, the influence degree of the exposure value on the image brightness within the first image area can be determined (the exposure value here can refer to the default exposure value or the basic set exposure value), so that the first exposure parameter with the best shooting effect on the first image area can be selected.

[0040] Step 108: Shoot a multimedia file according to the first exposure parameter.

[0041] After determining the first exposure parameter, the subject is shot to obtain a multimedia file. The TOF sensor detects depth information in real time. The depth information obtained by the TOF sensor fits the usage scenario of the flash and can meet the strict timing requirements of the flash. Moreover, using the TOF sensor to obtain the depth information of the subject can effectively improve the exposure accuracy in the flash scenario.

[0042] During the shooting process, the electronic device can automatically adjust the first exposure parameter with reference to the first depth information of the first image area. Therefore, even if the user has little shooting experience or no shooting experience, images or videos with better picture quality can be shot in different scenarios. Thus, even if the user does not actively adjust the exposure parameter, satisfactory images or videos can be obtained, reducing the operation difficulty of the user and being beneficial to improving the shooting experience of the user.

[0043] In a possible embodiment, when the shooting preview interface is displayed, the shooting method further includes: obtaining second parameter information corresponding to a second image area in the shooting preview interface, where the second parameter information includes second depth information and second ambient brightness information; determining a second brightness influence coefficient of the second image area according to the second depth information and the second ambient brightness information; determining a second exposure parameter according to the second brightness influence coefficient, where the second exposure parameter of the second image area is different from the first exposure parameter of the first image area; shooting a multimedia file according to the first exposure parameter, including: shooting a multimedia file according to the first exposure parameter and the second exposure parameter.

[0044] In this embodiment, there is also a second image area in the shooting preview interface, that is, the shooting preview interface can be composed of at least two image areas. By obtaining the second parameter information of the second image area, the influence degree of the exposure value on the exposure brightness of the image in the first image area can be determined. Considering the brightness influence coefficients of different image areas comprehensively, the first exposure parameter and the second exposure parameter can be obtained more accurately, and different exposure processes can be performed on different image areas, so that a multimedia file with better effects can be shot.

[0045] In other embodiments, there are multiple image areas in the shooting preview interface, for example, a third image area is also included.

[0046] In a possible embodiment, determining the first brightness influence coefficient of the first image area according to the first depth information and the first ambient brightness information includes: determining preset parameter information corresponding to the first depth information and the first ambient brightness information, where the first depth information corresponds to the calibrated depth information in the preset parameter information, and the first ambient brightness information corresponds to the calibrated ambient brightness information in the preset parameter information; determining the first brightness influence coefficient of the first image area according to the preset brightness influence coefficient associated with the preset parameter information.

[0047] In this embodiment, after obtaining the first depth information and the first ambient brightness information of the first image area, the first depth information and the first ambient brightness information are matched with the preset parameter information, so as to obtain the first brightness influence coefficient corresponding to the current first depth information and the first ambient brightness information.

[0048] Specifically, the preset parameter information is pre-set calibration information, which includes multiple calibration depth information and multiple calibration ambient brightness information. Different combinations of calibration depth information and calibration ambient brightness information correspond to different preset influence coefficients. The obtained first depth information and first ambient brightness information are matched with the preset parameter information to obtain the calibration depth information that matches the first depth information and the calibration ambient brightness information that matches the first ambient brightness information, and then the preset brightness influence coefficient associated with the calibration depth information and the calibration ambient brightness information is determined, and the obtained preset brightness influence coefficient is used as the first brightness influence coefficient of the first image area.

[0049] By pre-associating the preset parameter information and the preset influence coefficient, after obtaining the first parameter information of the photographed object, the first brightness influence coefficient can be quickly obtained, which is beneficial to improving the real-time performance of adjusting the exposure parameter value, and thus beneficial to improving the shooting effect.

[0050] In a possible embodiment, the first image area includes multiple sub-areas; determining the first brightness influence coefficient of the first image area according to the preset brightness influence coefficient associated with the preset parameter information includes: determining the average value of the depth information of the multiple sub-areas; and performing interpolation calculation based on the average value and the first ambient brightness information to determine the first brightness influence coefficient of the first image area.

[0051] In this embodiment, there are usually multiple sub-areas in the shooting preview interface. For example, as shown in Figure 2 and Figure 3 Suppose the shooting preview interface includes 64×48 sub-areas. To improve the calculation speed and convenience, the 64×48 sub-blocks can be mapped into 16×16 image areas. Each sub-area has its own depth information (the number shown in each square represents its depth information). It is necessary to obtain the average value of the multiple depth information to obtain the depth information of the image area.

[0052] The preset parameter information includes calibration depth information and calibration ambient brightness information. It is difficult to cover all values of the calibration depth information and the calibration ambient brightness information. Therefore, after obtaining the depth information of the image area, it may not be possible to find the calibration depth information that matches this depth information in the preset parameter information. At this time, it is necessary to obtain the brightness influence coefficient by interpolation calculation.

[0053] Exemplarily, an example is given using the value a corresponding to the depth information depth of a certain image (the average value obtained from multiple depth information), the value b corresponding to the ambient brightness information Lux, and the brightness influence coefficient c. The value a is within the range of 20 to 30 (20 and 30 are the values corresponding to the calibrated depth information in the preset parameter information), and the value b is within the range of 400 to 500 (400 and 500 are the values corresponding to the calibrated ambient brightness information in the preset parameter information). Interpolation calculation is performed in the following manner:

[0054] (1) depth = 20, Lux = 400, c = k1; (2) depth = 20, Lux = 500, c = k2;

[0055] (3) depth = 30, Lux = 400, c = k3; (4) depth = 30, Lux = 500, c = k4;

[0056] When Depth = a and Lux = 400, the interpolated brightness influence coefficient is temp1: temp1 = k1 + (k3 - k1) × (a - 20) / (30 - 20);

[0057] When Depth = a and Lux = 500, the interpolated brightness influence coefficient is temp2: temp2 = k2 + (k4 - k2) × (a - 20) / (30 - 20);

[0058] Therefore, the first brightness influence coefficient K of this display block is: temp1 + (temp2 - temp1) × (b - 400) / (500 - 400).

[0059] Through the above calculation method, 256 K values can be obtained, namely: K1, K2......K256.

[0060] Through the above method, the brightness influence coefficients of multiple image regions can be calculated. Determining the brightness influence coefficient of the image region by interpolation calculation can improve the accuracy of obtaining the brightness influence coefficient and reduce the calibration difficulty in the early stage.

[0061] As Figure 4 shown, in a possible embodiment, determining the first exposure parameter according to the first brightness influence coefficient includes: determining the weight of the first brightness influence coefficient according to the first position of the first image region in the shooting preview interface, where the weight of the first brightness influence coefficient is associated with the distance from the first position to the geometric center of the shooting preview interface; determining the second brightness influence coefficient of the first image region according to the weight of the first brightness influence coefficient and the first brightness influence coefficient.

[0062] In this embodiment, after determining the brightness influence coefficients of multiple image regions, it is necessary to determine the weights of the brightness influence coefficients of different image regions. When determining the first exposure parameter, it is necessary to consider the influence degree of multiple brightness influence coefficients on the overall shooting effect. For an image region closer to the geometric center of the shooting preview interface, the corresponding brightness influence coefficient has a greater influence on the shooting picture. Therefore, the closer to the geometric center of the shooting preview interface, the higher the weight of the brightness influence coefficient, and vice versa.

[0063] Assume that the first image region is the entire preview interface. Then the calculation formula for the second brightness influence coefficient H is: H = (K1×W1 + K2×W2 + …… + K256×W256) / (16×16). W represents the weight of the brightness influence coefficient. Use the K values corresponding to the image regions in the first image region to calculate the weighted average.

[0064] Through the above formula, the second brightness influence coefficient corresponding to the overall region within the shooting preview interface can be calculated, and the first exposure parameter is determined according to the second brightness influence coefficient.

[0065] By applying weights to the first brightness influence coefficient, the accuracy of determining the value of the first exposure parameter can be further improved, which is beneficial to improving the shooting effect.

[0066] In a possible embodiment, a multimedia file is captured according to the first exposure parameter, including: before pre-flash shooting, collecting the first brightness value and the first sub-exposure value of the image within the shooting preview interface; during pre-flash shooting, collecting the second brightness value and the second sub-exposure value of the image within the shooting preview interface; determining the brightness change amount of the image within the shooting preview interface according to the first brightness value, the first sub-exposure value, the second brightness value, and the second sub-exposure value; obtaining the current ratio of the flash during main flash shooting and pre-flash shooting, and determining the third brightness value of the image within the shooting preview interface during main flash shooting according to the current ratio, the brightness change amount, the second brightness influence coefficient, and the first brightness value; determining the first exposure parameter according to the third brightness value, the first brightness value, and the first sub-exposure value; and capturing a multimedia file according to the first exposure parameter.

[0067] In this embodiment, during the shooting process, the flash is divided into pre-flash and main flash. Before pre-flash shooting, first obtain the first brightness value Y1 and the first sub-exposure value E1 of the image within the shooting preview interface. During pre-flash shooting, obtain the second brightness value Y2 and the second sub-exposure value E2 of the image within the shooting preview interface. In a possible application, it is necessary to obtain the second brightness value and the second sub-exposure value when the pre-flash shooting is stable.

[0068] Calculate the brightness increase Y3 of the image in the shooting preview interface under the condition of consistent exposure according to the current ratio R between the reference pre-flash and the main flash and the second brightness influence coefficient H, where Y3 = (E1 / E2)×Y2 - Y1. Estimate the third brightness value Y4 of the image in the shooting preview interface during main flash shooting according to the brightness increase, where Y4 = Y3×R×H + Y1. Finally, obtain the first exposure parameter E = Y4 / Y1×E1.

[0069] Determining the first exposure parameter in the above manner is conducive to obtaining an accurate shooting exposure value, thereby facilitating the improvement of the shooting effect.

[0070] In a possible embodiment, before obtaining the first parameter information corresponding to the first image area in the shooting preview interface, it further includes: collecting the calibration brightness values of the shooting calibration object under different calibration depth information conditions while keeping the calibrated environmental brightness information unchanged; determining the preset brightness influence coefficients of the shooting calibration object under different calibration depth information conditions according to the calibration depth information and the calibration brightness values.

[0071] In this embodiment, before shooting, it is necessary to calibrate the camera parameters. While keeping the environmental brightness unchanged, change the calibration depth information to determine the brightness values of the shooting calibration object under different calibration depth information conditions, and then determine the preset brightness influence coefficients according to the calibration depth information and the calibration brightness values.

[0072] As Figure 5 shown, for example, in an environment with uniform light illumination, for example, fixing the environmental brightness Lux = 500 and the exposure value, calculate the brightness values of the image when the flash is turned on under different depths (10, 20, 30......100). For example, when the calibration depth information is 10, the image brightness is 30, and when the calibration depth information is 50, the image brightness is 20. Taking the depth 50 as a reference of 1.0, so the brightness influence coefficient of depth 10 is 1.5, and so on for others.

[0073] It should be noted that during the calibration process, it is necessary to ensure that the shooting calibration object is at the center position of the shooting screen. Figures 5(a) and 5(b) show that the area occupied by the shooting calibration object in the entire preview interface is different under different depth information, so the areas for calculating the brightness are also different.

[0074] In a possible embodiment, before obtaining the first parameter information corresponding to the first image area in the shooting preview interface, it further includes: collecting the calibration brightness values of the shooting calibration object under different calibrated environmental brightness information conditions while keeping the calibration depth information of the shooting calibration object unchanged; determining the preset brightness influence coefficients of the shooting calibration object under different calibrated environmental brightness information conditions according to the calibrated environmental brightness information and the calibration brightness values.

[0075] In this embodiment, when calibrating the camera parameters, it is also necessary to change the ambient brightness while keeping the depth calibration depth unchanged, so as to determine the brightness values of the captured calibration object under different calibration ambient brightness information conditions. Then, a preset brightness influence coefficient is determined according to the calibration ambient brightness information and the calibration brightness value.

[0076] Exemplarily, while keeping the calibration depth information unchanged, the calibration ambient brightness information (100, 200, 300... 1000) is changed, so as to obtain a plurality of preset brightness influence coefficients.

[0077] In the shooting method provided by the embodiment of the present application, the execution subject may be a shooting device. In the embodiment of the present application, the shooting method executed by the shooting device is taken as an example to illustrate the shooting device provided by the embodiment of the present application.
