Terminal devices such as smartphones have become an unavailable part of life of people, and people seem to be away from terminal devices such as smartphones in various scenes of life. The photographing function of the terminal device can photograph images and record life, and various photographing modes such as jumping by a photographer, capturing a photograph of the photographer in the air by the photographer, and the like have also been studied. However, the above-described various photographing methods depend on photographing skills and proficiency of the user, and thus the quality and efficiency of the photographed image cannot be ensured.

In a specific scenario, a photographer takes an image of a jump posture for a photographer, the photographer starts a photographing procedure and adjusts a photographing direction so that the photographer enters into a viewfinder, and then the photographer jumps, while the photographer notices a jump height of the photographer and manually triggers the photographing procedure at an appropriate height to perform photographing (for example, presses a photographing key). However, the time of the shot person in the air is very short, and the shot person cannot guarantee that shooting is accurately triggered at the moment of proper height, so that more satisfactory images can be shot only by repeated shooting, and even satisfactory images cannot be acquired by repeated shooting.

Based on this, in a first aspect, at least one embodiment of the present disclosure provides a photographing method, please refer to fig. 1, which illustrates a flow of the method, including steps S101 to S102.

The photographing method may be performed by a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or other terminal devices, for example, by a processor invoking computer readable instructions stored in a memory.

The terminal device has a photographing program, the photographing program may have a skip photographing mode, and the photographing method may be automatically performed when the skip photographing mode of the photographing program is started.

In step S101, when there is a movement in the vertical direction of a target object in a viewfinder of a photographing program, movement information of the target object is acquired.

The target object may be a photographer. When a plurality of objects exist in the view-finding frame, the depth of each object can be obtained, and the object with the smallest depth is determined as a target object; when a plurality of objects exist in the view-finding frame, one of the objects can be determined to be a target object according to the selected operation of the user. There is a vertical movement of the target object, which may be a jump of the target object.

When the motion information of the target object is acquired, the motion information can be acquired according to a certain frequency, namely, the motion information from the initial time of the motion or the time when the motion information is acquired last time to the current time is acquired every preset time.

In some embodiments, the terminal device has a dynamic vision sensor (Dynamic Vision Sensor, DVS) for acquiring motion information within the viewfinder. The dynamic vision sensor is a sensor based on motion perception, which only outputs the information of a moving object of a shooting picture, and the pixel part corresponding to the object which does not move does not output any information, so that the sensor can be ensured to output the motion information of the moving object at a very high frame rate (basically up to 1000 fps). The motion information may be an original position of a pixel corresponding to the moving object, and a motion distance and a motion direction of the pixel.

Therefore, when the motion information of the target object is acquired in this step, the motion information of the target object acquired by the dynamic vision sensor may be acquired first, and then the motion information of the target object acquired by the dynamic vision sensor may be converted into the motion information of the target object in the viewfinder. The relation between the motion information acquired by the dynamic vision sensor and the motion information in the view frame is preconfigured in the terminal equipment, so that the motion information of the target object acquired by the dynamic vision sensor can be converted into the motion information of the target object in the view frame according to the relation, namely, the pixel position, the motion distance and the motion direction in the DVS image are registered to the RGB image in the view frame.

In step S102, the shooting procedure is triggered to shoot an image if the motion information meets a preset requirement.

After the motion information of the target object is acquired in step S101, the motion information may be processed, so as to determine whether the motion information meets a preset requirement. The preset requirement may be preset by the user, for example, the preset requirement may refer to that the movement speed of the target object reaches a certain threshold value, or that the movement height of the target object reaches a certain threshold value. In other words, the preset requirement refers to a state that a user wants to capture when manually capturing an image of a jumping posture of a subject in the related art.

Triggering a shooting program to shoot an image, namely automatically shooting the image. In the jumping process of the target object, one image can be shot, or a plurality of images can be shot, namely, the motion information of the target object in the process can meet one-time preset requirements, or meet multiple preset requirements.

In some embodiments of the present disclosure, the preset requirement may refer to that the user jumps to the highest point, so the motion information may be processed in the following manner, so as to determine whether the motion information of the target object meets the preset requirement: firstly, determining the movement speed of the target object according to the movement information of the target object; and then, under the condition that the movement speed of the target object is zero, determining that the movement information meets the preset requirement.

The user jumping process is divided into an upward movement sub-process and a downward movement sub-process, the upward movement ending time is the time when the user jumps to the highest point, the downward movement starting time is the time when the user jumps to the highest point, the upward movement speed is upward in the upward movement sub-process, the downward movement speed is downward in the downward movement sub-process, and the user speed is zero.

After the motion information of the target object is acquired for the first time, the motion speed of the target object from the initial time to the time when the motion information is acquired at this time can be determined, and the speed is determined to be the initial speed of the target object jumping upwards, so that the duration from the initial time to the highest point time (namely, the time when the speed is zero) can be calculated according to the initial speed, and the motion information is determined to meet the preset requirement when the motion duration of the target object meets the duration.

For example, the motion information includes a motion distance X of the target object in the viewfinder in the vertical direction, and the time interval t at which the motion information is acquired is known, and thus can be based onCalculating the movement velocity V from the movement distance and the time interval _init ：V _init ＝X/t。

The time period T between the initial speed calculation initial time and the highest point time (i.e., the time at which the speed is zero) can be calculated according to the following formula: t=v _init /g。

In this embodiment, the highest point of the movement of the target object is determined by focusing on the movement speed of the target object, which is simple and convenient, and very accurate to lock the moment of triggering shooting, thereby improving the quality and efficiency of the shot image.

In some embodiments of the present disclosure, the target height may be determined in advance according to a height calibration instruction for the viewfinder, for example, a user performs a calibration operation on a certain height in the viewfinder, so that a height calibration instruction may be generated. The preset requirement may mean that the user jumps to the highest point or jumps to the target height, and thus the motion information may be processed in a manner as shown in fig. 2, thereby determining whether the motion information of the target object meets the preset requirement, including steps S201 to S204.

In step S201, a movement speed of the target object is determined according to the movement information of the target object.

For example, the motion information includes a motion distance X of the target object in the viewfinder in the vertical direction, and a time interval t at which the motion information is acquired is known, so that the motion velocity V in the time interval can be calculated from the motion distance and the time interval _init ：V _init ＝X/t。

In step S202, a maximum height of the target object is determined from the initial height of the target object and the movement speed.

Optionally, after the motion information of the target object is obtained for the first time, the motion speed of the target object from the initial time to the time when the motion information is obtained this time can be determined, and the speed is determined as the initial speed of the target object jumping upwards, so that the duration and the motion distance between the initial time and the highest point time (i.e. the time when the speed is zero) can be calculated according to the initial speed.

Can be according toThe following formula calculates the time period T between the initial speed calculation initial time and the highest point time (i.e., the time at which the speed is zero): t=v _init And/g. The movement distance H between the initial velocity calculation initial time and the highest point time (i.e., the time at which the velocity is zero) can be calculated according to the following formula: h=v _init ² 2g, then according to the distance H and the initial height H _init Determination of maximum height H _max ：H+H _init 。

Optionally, the initial height of the target object is determined in advance according to the preview image and/or the motion information in the viewfinder. In one example, the preview image is divided into a target object portion and a background portion, and a first initial height of the target object is determined according to the target object portion, for example, a pixel height of a lowest point of the target object portion in a viewfinder is taken as the first initial height; determining a second initial height of the target object according to the motion information, for example, determining the second initial height according to an initial position of a lowest point of a pixel part of the target object included in the motion information acquired for the first time; the determining of the initial height of the target object according to the first initial height and the second initial height may preset rules, for example, when there is coincidence between the first initial height and the second initial height, the coincident portion is taken as the initial height of the target object, and when there is no coincidence between the first initial height and the second initial height, the second initial height is taken as the initial height of the target object.

In step S203, if the maximum height is less than or equal to a target height calibrated in advance, it is determined whether the motion information meets a preset requirement according to the motion information and the maximum height.

In one example, the motion height of the target object is determined according to the initial height and the motion information, for example, the initial speed is determined according to the motion distance and the time interval for acquiring the motion information after the motion information is acquired for the first time, and then the motion height of the target object can be determined according to the initial speed and the motion time; and then determining that the motion information meets the preset requirement under the condition that the motion height of the target object reaches the maximum height.

Alternatively, it may be directly determined that the moving height of the target object reaches the maximum height after the moving time of the target object reaches the time period T between the initial time and the highest point time (i.e., the time at which the velocity is zero).

In step S204, if the maximum height is higher than a target height calibrated in advance, it is determined whether the motion information meets a preset requirement according to the motion information and the target height.

In one example, the motion height of the target object is determined according to the initial height and the motion information, for example, the initial speed is determined according to the motion distance and the time interval for acquiring the motion information after the motion information is acquired for the first time, and then the motion height of the target object can be determined according to the initial speed and the motion time; and then determining that the motion information meets the preset requirement under the condition that the motion height of the target object reaches the target height.

Alternatively, the target height H may be determined _dest Then, according to the following formula, according to the initial height H _init Target height H _dest Determining a target time T to reach a target height _dest ：

And when the movement time of the target object reaches the target time T _dest And then, directly determining that the motion height of the target object reaches the target height.

In this embodiment, the user determines the target height through the calibration operation, where the target height is used to represent the shooting state wanted by the user, so that the image is shot after the target object jumps to the target height, and supplementary measures are also provided, that is, when the target object cannot jump to the target height, the image is shot when the target object jumps to the highest point, so that the problem that the image cannot be shot due to inaccurate calibration of the user or insufficient jump height of the target object is avoided, the success of one-time shooting is achieved, and the shooting efficiency and the user experience are improved.
