In order to solve the technical problems, the embodiment of the application provides a method and a device for determining photographing duration and electronic equipment. In the method, firstly, videos obtained by recording in the process of photographing and previewing M pictures by a camera application program of the electronic equipment to be tested are obtained, then, according to the recorded videos, the picture previewing time length and the picture generating time length of each picture in the M pictures are determined, and then, according to the picture previewing time length and the picture generating time length of each picture in the M pictures, the photographing time length of the electronic equipment to be tested is determined. In other words, in the method provided by the application, according to the video recorded in the photographing and previewing process of photographing M pictures by the camera application program of the electronic equipment to be tested, the picture previewing time and the picture generating time of each picture in the M pictures obtained by photographing the electronic equipment to be tested are accurately determined, and then the photographing time of the electronic equipment to be tested is accurately determined according to the picture previewing time and the picture generating time of each picture in the M pictures, so that the photographing time of the electronic equipment to be tested is accurately quantized, and subsequently, the photographing speed performance of the electronic equipment to be tested can be evaluated according to the accurately quantized photographing time, and the evaluation result is more accurate.

The method for determining the photographing time length provided by the application can be applied to the system for determining the photographing time length shown in fig. 1. As shown in fig. 1, the system may include: the electronic device under test 10, the three-party recording device 20, the photographic subject 30, the light source device 40 and the test electronic device 50.

The electronic device 10 to be tested has the functions of photographing and previewing. The three-party recording device 20 is used for recording the photographing and previewing process of the electronic device 10 to be tested. The three-party recording device 20 may have a high frame rate, i.e., the three-party recording device 20 records a large number of frames per second. In the embodiment of the present application, the three-party recording device 20 is taken as an example of a high frame rate camera.

Both the electronic device under test 10 and the three-way recording device 20 may be mounted on a stand (e.g., a tripod). The display screen of the electronic device under test 10 is located within the recording field of view of the three-party recording device 20. Illustratively, the three-party recording device 20 may be secured directly in front of the display screen of the electronic device under test 10 by a tripod.

The photographic subject 30 is facing the camera of the electronic device under test 10, and the straight line distance between the photographic subject 30 and the electronic device under test 10 is 1 meter. In general, the camera mode of the electronic device under test 10 may include portrait scenes and/or non-portrait scenes. And the camera processing algorithm corresponding to the portrait scene is generally different from the camera processing algorithm corresponding to the non-portrait scene. Therefore, in the embodiment provided by the present application, the photographing duration of the electronic device 10 to be tested may be determined based on the portrait scene and/or the non-portrait scene, and the specific content may refer to the content of the subsequent embodiment, which will not be described in detail herein. Based on this, the photographic subject 30 may include a graphic card (e.g., a standard color card, etc.) and/or a head mold, etc. The image card can be used for a non-portrait scene, and the head model can be used for a portrait scene.

The light source device 40 may include light source devices of various application scenes, for example, may include light source devices of low, medium, high dynamic range, etc. application scenes. In specific implementation, the parameters of the light source device 40 may be adjusted, so that the light source device 40 may be adjusted to be a light source in the aforementioned various application scenarios, which is not limited by the present application. Further, the number of the light source devices 40 may be one or more, and the present application is not limited thereto. In fig. 1, an example is illustrated in which the light source device 40 includes two light source devices.

The test electronic device 50 may be communicatively coupled to the electronic device under test 10 and/or the three-way recording device 20 by a wired connection or a wireless connection. The test electronic device 50 may obtain, from the three-party recording device 20, a video recorded by the three-party recording device 20 during the photographing and previewing process of the electronic device 10 to be tested, and may be used to determine the photographing duration of the electronic device 10 to be tested according to the video.

When the photographing time length of the electronic device 10 to be measured needs to be determined, the photographing time length of the electronic device 10 to be measured may be determined through the system shown in fig. 1.

In particular, before determining the photographing duration of the electronic device 10 to be tested, the photographing object 30 is first selected, for example, a graphic card is selected as the photographing object 30. The card is then fixed to the gray plate. Then, the electronic device 10 to be tested is set at a position 1 m away from the graphics card, and the fixed position of the graphics card on the dust board is adjusted, so that the graphics card is located at the center of the view frame of the electronic device 10 to be tested and is completely displayed in the view frame, and when the electronic device 10 to be tested shoots the graphics card, the composition of the graphics card in the view frame of the electronic device 10 to be tested is a standardized composition. After the adjustment, the electronic device 10 to be tested is fixed by the tripod. The position of the graphics card and the electronic device under test 10 will not be changed in the process of determining the photographing time length of the electronic device under test 10 later.

Then, the three-party recording device 20 is disposed in front of the electronic device 10 to be measured, and the position of the three-party recording device 20 is adjusted so that the electronic device 10 to be measured is located in the shooting visual field range (or may also be referred to as the recording visual field range) of the three-party recording device 20, and the position of the three-party recording device 20 is not changed in the process of determining the shooting duration of the electronic device 10 to be measured.

After that, the light source device 40 is turned on, and the parameters of the light source device 40 are adjusted to a desired application scene, for example, the parameters of the light source device 40 are adjusted to a low-light application scene.

After the parameters of the light source device 40 are adjusted, the three-party recording device 20 is started, and the electronic device 10 to be tested is recorded through the three-party recording device 20 in the subsequent photographing and previewing process. Then, the camera application program of the electronic device 10 to be tested is started to run, and the picture card is photographed and previewed through the camera application program of the electronic device 10 to be tested.

As shown in fig. 2 (a), a user may trigger the camera application program to call the camera of the electronic device to be tested 10 to take a picture of the picture card by clicking the shutter button 60 on the preview interface (or may also be referred to as a shooting interface) of the camera application program of the electronic device to be tested 10, so as to obtain the 1 st picture of the picture card. Thereafter, as shown in fig. 2 (b), when the 1 st picture of the graphic card fills the image thumbnail frame 70 in the preview interface (i.e., the 1 st picture of the graphic card is completely displayed in the image thumbnail frame 70 of the preview interface), the user may trigger the electronic device 10 to be tested to load and display the 1 st picture of the graphic card on the detail interface of the camera application program by clicking the operation of the image thumbnail frame 70, and when the 1 st picture of the graphic card is completely loaded, the 1 st picture of the graphic card may be completely displayed on the detail interface of the camera application program as shown in fig. 2 (c), so far, the process of photographing the graphic card and generating the 1 st picture of the graphic card by the electronic device 10 to be tested is completed.

And then returning to the preview interface of the camera application program of the electronic device 10 to be tested again, and taking the 2 nd picture of the picture card according to the mode shown in fig. 2. Similarly, the 3 rd, … … th and M th pictures of the picture card can be obtained in the manner described above. M may be an integer greater than or equal to 1. The specific value of M may be set according to the requirements of the actual application scenario, for example, M may be set to 3.

In the above manner, after the M pictures of the graphics card are captured by the camera application program of the electronic device 10 to be tested, the recording process of the three-party recording device 20 may be stopped. Then, the video of the photographing and previewing process of the M pictures photographed by the camera application of the electronic device 10 to be tested, that is, the video obtained by recording the photographing and previewing process of the M pictures photographed by the camera application of the electronic device 10 to be tested (hereinafter referred to as photographing video of the electronic device to be tested) by the three-party recording device 20 may be stored.

It should be noted that, after obtaining the M pictures of the picture card in the above manner, other light sources may be switched, for example, parameters of the light source device 40 may be adjusted to application scenes such as a middle-bright, high-bright or high-dynamic range, and then in the switched light source application scenes, the shooting object 30 is shot and previewed in the above manner, so as to determine shooting durations of the electronic device 10 to be tested in various light source application scenes. Alternatively, the shooting object 30 may be switched, for example, the shooting object 30 is switched to a head model, and in a portrait scene, the shooting and previewing are performed on the head model by the electronic device 10 to be tested, and then, the shooting duration of the electronic device 10 to be tested in the portrait scene may be determined. Subsequently, when the photographing speed performance of the electronic device 10 to be tested is evaluated, the photographing time length of the electronic device 10 to be tested in various light sources and application scenes can be fused, and the photographing speed performance of the electronic device 10 to be tested is evaluated.

According to the requirements of actual application scenes, after the photographing videos of the electronic device 10 to be tested in various application scenes are recorded by the three-party recording device 20, the test electronic device 50 can obtain the photographing videos of the electronic device 10 to be tested from the three-party recording device 20, and then determine the photographing duration of the electronic device 10 to be tested according to the obtained photographing videos, and the specific content can refer to the content of the subsequent embodiments, which will not be described in detail herein.

The image preview duration of the nth image in the M images is a duration from when the electronic device to be tested receives a photographing operation for photographing the nth image (i.e., a shutter button of a camera application of the electronic device to be tested starts to change) to when an image thumbnail frame of a preview interface (or referred to as a photographing interface) of the camera application of the electronic device to be tested completely displays the nth image (i.e., the image thumbnail frame is filled with the nth image). Before shooting the nth picture, the user clicks a shutter button of a preview interface of a camera application program of the electronic device to be tested, and through the operation, the camera application program of the electronic device to be tested can be triggered to call a camera of the electronic device to be tested to shoot the nth picture. The time length for generating the nth picture is the time length from the complete display of the nth picture by the image thumbnail frame of the preview interface of the camera application program of the electronic device to be tested to the complete display of the nth picture (namely, the loading of the nth picture is completed) by the detail interface of the camera application program. N is an integer greater than or equal to 1 and less than or equal to M.

It is known from the foregoing embodiments that the three-party recording device may be a high frame rate camera. Therefore, in the photographing video of the electronic device to be tested, the photographing process and the preview process of each of the M pictures taken by the electronic device to be tested may include multiple frames of images. Therefore, before determining the image preview time and the image generation time of each image in the M images shot by the electronic device to be tested according to the shot video, the shot video needs to be subjected to framing processing to obtain each frame of image included in the shot video. And then, according to each frame of image included in the photographed video, determining the picture preview time length and the picture generation time length of each picture in M pictures photographed by the electronic equipment to be tested.

Next, taking an nth picture of the M pictures as an example, a specific implementation manner of determining the graph preview duration and the graph generation duration of each picture of the M pictures is described. The determining manner of the graph preview time length and the graph generation time length of each of the M pictures can refer to the specific implementation manner of determining the graph preview time length and the graph generation time length of the nth picture.

Illustratively, determining the graph preview duration and the graph generation duration of the nth picture may be referred to the embodiment shown in fig. 6. Fig. 6 is a flowchart of a method for determining a preview duration and a generation duration of an nth picture according to an embodiment of the present application. As shown in fig. 6, the method may include the steps of:

That is, the first photographing time refers to the photographing time of the first frame image in which the shutter button of the camera application of the electronic device to be tested changes after the shutter button is clicked before the nth picture is photographed in all the frame images included in the photographed video.

The second shooting time is the shooting time of a first frame image of the N-th picture in which an image thumbnail frame in a camera application program of the electronic equipment to be detected in the shooting video is completely displayed. The second shooting time refers to the shooting time of the first frame image in which the image thumbnail frame of the camera application program is filled after the electronic device to be tested shoots the nth picture in all the frame images included in the shooting video.

The third shooting time is the shooting time of the first frame image of the nth picture completely displayed by the detail interface of the camera application program of the electronic equipment to be tested in the shooting video. The third shooting time refers to the shooting time of the first frame image after the electronic device to be tested shoots the nth picture in all frame images included in the shooting video.

Based on this, determining the first photographing time may be implemented as follows: finding out a first frame image of the shooting operation of the electronic equipment to be detected, which is received by the electronic equipment to be detected and used for shooting an N-th picture, from all frame images included in the shooting video of the electronic equipment to be detected, namely, after a shutter button of a camera application program of the electronic equipment to be detected is clicked before the N-th picture is shot, recording the first frame image as a first image; determining a shooting time (recording time) of a first image according to the shooting time of each frame of image included in the photographed video; the photographing time of the first image is determined as the first photographing time.

The determination of the second photographing time may be achieved as follows: finding out a first frame image of which the image thumbnail frame completely displays an N-th picture in a camera application program of the electronic equipment to be detected from all frame images included in a shooting video of the electronic equipment to be detected, namely, finding out the first frame image of which the image thumbnail frame of the camera application program is filled up after the electronic equipment to be detected shoots the N-th picture, and marking the first frame image as a second image; determining the shooting time of a second image according to the shooting time of each frame of image included in the shooting video; the photographing time of the second image is determined as the second photographing time.

The determination of the third photographing time may be implemented as follows: finding out a first frame image of an N-th picture displayed completely on a detail interface of a camera application program of the electronic equipment to be detected from all frame images included in a photographing video of the electronic equipment to be detected, namely, finding out the first frame image of the N-th picture loaded after the electronic equipment to be detected photographs the N-th picture, and marking the first frame image as a third image; determining the shooting time of a third image according to the shooting time of each frame of image included in the shooting video; and determining the shooting time of the third image as the third shooting time.

The first image and the second image can be found out from all frame images included in the photographed video of the electronic device to be tested through selection operation of a tester.

The embodiment shown in fig. 7 can be referred to by acquiring the third image according to the photographed video of the electronic device to be tested, that is, by finding the third image from all the frame images included in the electronic device to be tested.

That is, the 1 st frame image and the 3 rd frame image are extracted from the H frame image, and then the sharpness difference between the sharpness average value of the 1 st frame image and the sharpness average value of the 3 rd frame image, and the brightness difference between the brightness average value of the 1 st frame image and the brightness average value of the 3 rd frame image are determined. If the determined definition difference is smaller than the first preset threshold value and the brightness difference is smaller than the second preset threshold value, determining that the 1 st frame image in the H frame images is a third image. Or if the determined definition difference is greater than or equal to a first preset threshold value and/or the brightness difference is greater than or equal to a second preset threshold value, sequentially extracting the 2 nd frame image and the 4 th frame image from the H frame image, and then determining the definition difference between the definition average value of the 2 nd frame image and the definition average value of the 4 th frame image and the brightness difference between the brightness average value of the 2 nd frame image and the brightness average value of the 4 th frame image. If the determined definition difference is smaller than the first preset threshold value and the brightness difference is smaller than the second preset threshold value, determining that the 2 nd frame image in the H frame images is a third image. And so on until the third image is determined.

Further, the following formula can be adopted And determining the definition difference between the definition average value of the K frame image and the definition average value of the K+2 frame image. Wherein DeltaC _k Indicating poor definition, C _k Represents the definition average value of the K frame image, C _k+2 The mean value of the sharpness of the k+2 frame image is represented.

Further, the following formula can be adoptedA luminance difference between the luminance average of the K-th frame image and the luminance average of the k+2-th frame image is determined. Wherein DeltaL _k Representing the difference in brightness, L _k Representing the luminance average value of the K-th frame image, L _k+2 The luminance average of the k+2 frame image is represented.

The first preset threshold and the second preset threshold can be set according to the requirements of the actual application scene. For example, the first preset threshold may be set to 5% and the second preset threshold may be set to 1%.

It should be noted that, in some other optional application scenarios, the third image may also be determined by determining a sharpness difference and a brightness difference between the kth frame image and the kth+1th frame image in the H frame image. Alternatively, the third image may be also determined by determining a difference in sharpness and a difference in brightness between a kth frame image and a kth+3 frame image among the H frame images. The application is not limited in this regard.
