The mobile terminal has basically replaced the traditional camera for shooting.
When shooting through a mobile terminal, a user often has a focusing requirement. The currently used focusing shooting schemes mainly include the following two types: the first focusing shooting scheme is as follows: and clicking a focus area in the preview picture, sliding two fingers in the preview picture, adjusting the zoom multiple by adjusting the distance between the two fingers to focus, and then clicking a shooting button to shoot. The second focusing scheme is as follows: and clicking a focusing area in the preview picture, adjusting the zoom multiple to focus by controlling a zoom multiple adjusting button in the preview interface through a finger, and then clicking a shooting button to shoot.
The inventor has found through long-term research that in the scheme of focusing shooting, when a user takes a picture with one hand, the focusing area is far away from the shutter area, the operation is inconvenient, in addition, the focusing is time-efficient, and the user may fail to focus the picture by moving fingers to the shutter after focusing.
In view of the above problems, the inventor provides a shooting method, a shooting device, a mobile terminal and a storage medium provided in the embodiments of the present application, which can enable a user to perform focusing and trigger completion of shooting operations by sliding a shooting button to a corresponding position in a preview area, thereby simplifying user operations and improving shooting experience. Specific shooting methods are described in detail in the following examples
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a shooting method according to an embodiment of the present disclosure. In a specific embodiment, the photographing method is applied to the photographing apparatus 400 as shown in fig. 12 and the mobile terminal 100 (fig. 13) equipped with the photographing apparatus 400. The following will describe a specific process of this embodiment by taking a mobile terminal as an example, and it is understood that the mobile terminal applied in this embodiment may be a smart phone, a tablet computer, a smart watch, smart glasses, and the like, which is not limited herein. As will be described in detail with respect to the flow shown in fig. 1, the shooting method may specifically include the following steps:
step S110: and displaying a shooting interface, wherein the shooting interface comprises a preview area and a shooting button.
In the embodiment of the present application, the shooting interface is an interface displayed in a shooting mode. The mobile terminal can display a shooting interface when entering a shooting mode. The shooting mode may be that the mobile terminal operates the system camera in the foreground to enter the shooting mode and displays a shooting interface of the system camera when detecting that the system camera is turned on.
The shooting mode can also be that when the mobile terminal detects that the third-party camera application is started, the third-party camera application is operated in the foreground to enter the shooting mode, and a shooting interface of the third-party system camera is displayed; the shooting mode can also be that the mobile terminal calls a camera to shoot when detecting that the application runs, and enters the shooting mode and displays a shooting interface. The starting of the camera application such as the system camera, the third-party camera application and the like can be triggered by detecting that a control (icon) of the application is touched, or certainly, by means of voice control and the like, and is not limited herein.
In some embodiments, the capture interface may include: a preview area and a capture button. The preview area is used for displaying a shooting preview image; the shooting button is used to trigger image shooting, and may be referred to as a shutter button or a shutter button. For example, referring to fig. 2, the shooting interface a1 includes a preview area a2 and a shooting button A3, the preview area a2 is used to show a shooting preview image, the shooting button A3 can be used to control image shooting, and when the shooting button A3 is clicked, the camera can be controlled to perform image shooting.
Of course, the shooting interface may also include other content, for example, the shooting interface may also include: a selection area of the shooting mode, an album button, a camera switching button, etc., and of course, the specific contents in the shooting interface may be limited. The selection area of the shooting mode is used for selecting different shooting modes, for example, shooting modes such as night scenes, videos, portrait, photos and the like can be selected; the photo album button is used for triggering the starting of the photo album; the camera switching button may be used to switch the front camera and the rear camera, and is not limited herein.
Step S120: and responding to the sliding operation of the shooting button, and determining a shooting focus according to the end position when the end position of the sliding operation is positioned in the preview area.
In the embodiment of the application, the mobile terminal may detect a touch operation in the shooting interface, where the touch operation may include a press operation, a click operation, a slide operation, and the like that are performed in the shooting interface. When the touch operation of the shooting button in the shooting interface is detected, the mobile terminal can respond to the touch operation and judge whether the touch operation is a sliding operation. The sliding operation of the shooting button refers to touch control of the shooting button, and after the shooting button is selected, the sliding operation is performed under the condition that the finger does not leave the screen.
In the embodiment of the application, when the sliding operation of the shooting button in the shooting interface is detected, the mobile terminal may determine whether the end point position of the sliding operation is located in the preview area in response to the sliding operation, that is, determine whether the end point position of the sliding track of the sliding operation is located in the preview area after the sliding operation is stopped. If the end point position of the sliding operation is located in the preview area, it indicates that the user needs to focus on the position currently, so that the focus area corresponding to the end point position in the preview image of the preview area can be determined according to the end point position to obtain the shooting focus. Optionally, the focusing area may be an area with a preset size with the end point position as a center, and a specific numerical value of the preset size may not be limited. Of course, the focusing area may be a preset size area with the end point position not at the center, that is, the end point position only needs to be in the focusing area.
Step S130: and focusing according to the shooting focus.
In the embodiment of the application, after the mobile terminal determines the shooting focus, focusing can be performed according to the shooting focus. The focusing refers to the process of making the imaged object clear by changing the object distance and the distance position, also called focusing. The mobile terminal can use contrast focusing, phase focusing, triangular distance measurement focusing and the like for focusing, the specific focusing mode can be not limited, taking contrast focusing as an example, the contrast focusing is to use an algorithm to identify the contrast of a picture, when the contrast is the highest, the success of focusing is confirmed, and as the focusing lens starts to move, the picture is gradually clear, and the contrast starts to rise; when the picture is clearest and the contrast is highest, the picture is in a focusing state, but the camera does not know the picture, so the lens is continuously moved, and when the contrast is found to be reduced; moving the lens further, finding that the contrast drops further, the camera knows that the focus has been missed; and the lens is retracted to the position with the highest contrast ratio to finish focusing.
Step S140: and triggering shooting operation after the focusing is finished.
In the embodiment of the application, after the mobile terminal completes the focusing operation, the shooting operation can be triggered, namely the shooting operation is automatically executed to shoot a scene, so that a shot image is obtained. Therefore, the user can perform focusing operation and trigger shooting operation by sliding the shooting button to the position needing focusing, and great convenience is brought to the user for focusing and shooting operation during shooting.
For example, referring to fig. 3 and 4, the mobile terminal may respond to the sliding operation of the photographing button a2, and when the sliding operation slides to a position B in the preview area A3, the photographing focus may be determined according to the position B, and after focusing is performed, the photographing operation may be performed.
According to the shooting method provided by the embodiment of the application, the shooting interface is displayed and comprises the preview area and the shooting button, the shooting button is responded to slide operation, when the end point position of the slide operation is located in the preview area, the shooting focus is determined according to the end point position, then focusing is carried out according to the shooting focus, and after the focusing is finished, the shooting operation is triggered. Therefore, the user can focus and trigger to complete the shooting operation by sliding the shooting button to the corresponding position of the preview area, the operation of the user is simplified, and the shooting experience is improved.
Referring to fig. 5, fig. 5 is a schematic flow chart illustrating a shooting method according to another embodiment of the present application. The shooting method is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 5, where the shooting method may specifically include the following steps:
step S210: and displaying a shooting interface, wherein the shooting interface comprises a preview area and a shooting button.
In the embodiment of the present application, step S210 may refer to the contents of the foregoing embodiments, which are not described herein again.
Step S220: and responding to the pressing operation of the shooting button, and judging whether the pressing operation meets a preset pressing condition.
In the embodiment of the application, in order to avoid the situation that the user triggers focusing and shooting operations by mistake, the mobile terminal can judge whether the pressing operation meets the preset pressing condition or not when the pressing operation of the shooting button in the shooting interface is detected. As can be understood, after the mobile terminal displays the shooting interface, when a user operates the mobile terminal, the situation that the shooting button is touched and slid by mistake may exist, and the situation that the focusing is triggered and the shooting is triggered by mistake just after the user slides to the preview area; in addition, if the user needs to focus and shoot and move the shooting button, the user needs to touch the shooting button first and detect the pressing operation of the shooting button. Therefore, a preset pressing condition may be set, and in the case where a pressing operation of the photographing button is detected, it is necessary to determine whether the pressing operation determines the preset pressing condition; if the pressing operation meets the preset pressing condition, the user needs to perform focusing operation and follow-up shooting triggering operation; if the pressing operation does not satisfy the preset pressing condition, the previous operation of the user does not indicate that the user needs to perform focusing and subsequent shooting triggering operation, for example, the pressing operation is that the user normally clicks a shooting button to trigger shooting operation.
In some embodiments, the compression condition comprises at least one of the following conditions:
the pressing duration corresponding to the pressing operation is longer than a first duration; the pressing area corresponding to the pressing operation is larger than the preset area; and the pressing pressure value corresponding to the pressing operation is greater than the preset pressure value.
In this embodiment, the preset pressing condition includes that a pressing duration corresponding to the pressing operation is longer than a first duration, if the pressing operation on the shooting button in the shooting interface is detected, it may be determined whether the pressing duration of the pressing operation is longer than the first duration, if the pressing duration of the pressing operation is longer than the first duration, it is determined that the pressing operation satisfies the preset pressing condition, and otherwise, it may be determined that the pressing operation does not satisfy the preset pressing condition. The first time period may be 1 second, 1.5 seconds, 2 seconds, or the like, and the specific value may not be limited.
In this embodiment, when the preset pressing condition includes that the pressing area corresponding to the pressing operation is larger than the preset area, and the mobile terminal detects the pressing operation on the shooting button, it may be determined whether the pressing area of the pressing operation is larger than the preset area, and if the pressing area of the pressing operation is larger than the preset area, it is determined that the pressing operation satisfies the preset pressing condition, and otherwise, it may be determined that the pressing operation does not satisfy the preset pressing condition. The specific value of the preset area may not be limited.
In this embodiment, the preset pressing condition includes that when the pressing pressure value corresponding to the pressing operation is greater than the preset pressure value, and the mobile terminal detects the pressing operation on the shooting button, it may be determined whether the pressing force degree of the pressing operation is greater than the preset pressure value, and if the pressing force degree of the pressing operation is greater than the preset pressure value, it is determined that the pressing operation satisfies the preset pressing condition, and otherwise, it may be determined that the pressing operation does not satisfy the preset pressing condition. The specific value of the preset pressure value may not be limited.
In some embodiments, the above preset pressing conditions may also be combined, for example, the pressing operation needs to satisfy the pressing pressure value being greater than the preset pressing pressure value and the pressing duration being greater than the first duration.
Step S230: and if the pressing operation meets the preset pressing condition, responding to the sliding operation aiming at the shooting button, and determining a shooting focus according to the end point position when the end point position of the sliding operation is positioned in the preview area.
In the embodiment of the present application, after it is detected whether the pressing operation satisfies the preset pressing condition, it may be determined whether to perform the determination of the shooting focus and the subsequent steps according to the detection result. If the pressing operation meets the preset pressing condition, the mobile terminal can respond to the sliding operation of the shooting button, and when the end point position of the sliding operation is located in the preview area, the shooting focus is determined according to the end point position. That is, if the pressing operation satisfies the preset pressing condition, if it is detected that the shooting button is slid to the preview area, the determination of the shooting focus and the subsequent steps may be performed. If the pressing operation does not satisfy the preset pressing condition, even if the sliding operation is detected, the sliding operation is not responded, namely, the determination of the shooting focus and the subsequent steps are not executed.
Step S240: and focusing according to the shooting focus.
Step S250: and triggering shooting operation after the focusing is finished.
In the embodiment of the present application, step S240 and step S250 may refer to contents of other embodiments, which are not described herein again.
According to the shooting method provided by the embodiment of the application, the shooting interface is displayed and comprises the preview area and the shooting button, the shooting button is responded to slide operation, when the end point position of the slide operation is located in the preview area, the shooting focus is determined according to the end point position, then focusing is carried out according to the shooting focus, and after the focusing is finished, the shooting operation is triggered. Therefore, the user can focus and trigger to complete the shooting operation by sliding the shooting button to the corresponding position of the preview area, the operation of the user is simplified, and the shooting experience is improved. In addition, when the pressing operation of the shooting button is detected, the sliding operation and the subsequent steps of the shooting button are responded to be executed under the condition that the pressing operation meets the preset pressing condition, and the focusing and shooting operation can be effectively prevented from being triggered by mistake.
Referring to fig. 6, fig. 6 is a schematic flow chart illustrating a shooting method according to another embodiment of the present application. The shooting method is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 6, where the shooting method may specifically include the following steps:
step S310: and displaying a shooting interface, wherein the shooting interface comprises a preview area and a shooting button.
In the embodiment of the present application, step S310 may refer to the contents of other embodiments, which are not described herein again.
Step S320: and responding to the sliding operation of the shooting button, and determining a shooting focus according to the end position when the end position of the sliding operation is positioned in the preview area.
In the embodiment of the application, when the mobile terminal detects the sliding operation of the shooting button in the shooting interface, and if the end point position of the sliding operation is located in the preview area, the mobile terminal determines the shooting focus according to the end point position.
In some embodiments, when the mobile terminal detects a sliding operation on the shooting button, the mobile terminal may further display an indication control in response to the sliding operation on the shooting button, and control the indication control to move according to a sliding track of the sliding operation. The indication control is used for indicating the end position of the sliding operation.
In this embodiment, in order to facilitate the user to know the position to which the current sliding operation slides, the mobile terminal may display an indication control, where the indication control moves along the sliding track of the sliding operation, that is, to which position the sliding operation currently slides, the indication control also moves along the position.
In this embodiment, the specific presentation form of the indication control may not be limited. For example, referring to fig. 7, fig. 8 and fig. 9, the indication control a4 may be a circular control, and when the sliding operation is a sliding operation, the indication control a4 moves upward along with the sliding track. For example, the indication control a4 may be a mirror image of the shoot button. Through the mode, the reality sense of the sliding shooting button can be improved when the user slides the shooting button.
In some embodiments, when the mobile terminal detects a sliding operation on the shooting button, the shooting button in the shooting interface can be controlled to move in response to the sliding operation on the shooting button, and the shooting button moves along a sliding track of the sliding operation. By the mode, the user can feel the real experience of moving the shooting button.
In this embodiment, since the shooting button performs the position movement, the mobile terminal may subsequently complete the shooting operation, and after the shooting is completed, control the shooting button to move back to the initial position in the shooting interface. As one mode, the mobile terminal may control the shooting button to move back to an initial position in the shooting interface according to a sliding track of the sliding operation on the shooting button; alternatively, the mobile terminal may determine a shortest path for the photographing button to move from the current position back to the initial position, and then control the photographing button to move back to the initial position in the photographing interface according to the shortest path. Through the mode, the mobile terminal can display the animation effect of the restoration of the shooting button, and the user experience is improved.
In some embodiments, when the sliding operation of the shooting button is detected, in order to avoid the user from triggering focusing by mistake and triggering the shooting operation, a sliding condition of the sliding operation can be set. The sliding condition may be: the sliding track meets the preset sliding track, the sliding length is greater than the specified length, and the like. For example, after the user slides the shooting button to satisfy the sliding operation of the preset sliding track, the user slides to the position where focusing is desired, and then the focusing and shooting operations can be triggered.
Step S330: and focusing according to the shooting focus.
In the embodiment of the present application, step S330 may refer to the contents of other embodiments, which are not described herein again.
Step S340: and after the focusing is finished, triggering the shooting operation when the finger is detected to leave the screen.
In the embodiment of the application, after the mobile terminal completes the focusing operation, the user may need to determine whether the effect of the focused preview image is the focusing effect that the user wants, so that the shooting operation may be triggered temporarily but when the user detects that the finger leaves the screen, the shooting operation is triggered, that is, the shooting operation is automatically executed when the user looses the hand, and the scene is shot to obtain the shot image. Therefore, the user can perform focusing operation and trigger shooting operation by sliding the shooting button to the position needing focusing, and great convenience is brought to the user for focusing and shooting operation during shooting.
In some embodiments, after the mobile terminal completes the focusing operation, if the user's finger does not leave the screen and the user determines that the focused preview image is not the desired focusing effect, the user may re-determine the photographing focus according to the end position of the new sliding operation in response to a new sliding operation performed at the above end position, and then perform focusing according to the re-determined photographing focus. After focusing is completed, when the finger is detected to leave the screen, shooting operation is triggered. Of course, if the user is still unsatisfied with the focusing effect, the user can continue to perform new sliding operation until the focusing effect is the focusing effect desired by the user, and then release the hand to enable the mobile terminal to detect that the finger leaves the screen, so as to trigger the shooting operation.
In some embodiments, the shooting method provided in this embodiment of the present application may also be combined with the shooting method provided in the previous embodiment, that is, after the shooting interface is displayed, whether the pressing operation meets the preset pressing condition is determined in response to the pressing operation on the shooting button; if the pressing operation meets the preset pressing condition, responding to the sliding operation aiming at the shooting button, and determining a shooting focus according to the end position when the end position of the sliding operation is positioned in the preview area; when focusing is completed, when the finger is detected to leave the screen, shooting operation is triggered.
In some embodiments, as a variant example of triggering a shooting operation by using a finger to leave a screen, after focusing is completed, the mobile terminal may acquire a face image by using a front-facing camera, determine whether a user's face performs a corresponding facial expression action according to the acquired face image, and trigger the shooting operation when the corresponding facial expression action is detected. The facial expression action may be blinking, beeping, or the like, and the specific facial expression action may not be limited. For example, when the facial expression is used as a blinking motion, the mobile terminal may continuously acquire facial images, and when it is determined that a human face blinks continuously (for example, blinks 3 times) according to a plurality of continuously acquired facial images, a shooting operation is triggered.
In other embodiments, as a modified example of triggering a shooting operation by using a finger to leave a screen, after focusing is completed, the mobile terminal may collect voice through a microphone, perform voice recognition on the collected voice after the voice is collected, determine whether a voice recognition result includes a preset keyword, and trigger the shooting operation if the voice recognition result includes the preset keyword.
According to the shooting method provided by the embodiment of the application, the shooting interface is displayed and comprises the preview area and the shooting button, the shooting button is responded to slide operation, when the end point position of the slide operation is located in the preview area, the shooting focus is determined according to the end point position, then focusing is carried out according to the shooting focus, and after the focusing is finished, the shooting operation is triggered. Therefore, the user can focus and trigger to complete the shooting operation by sliding the shooting button to the corresponding position of the preview area, the operation of the user is simplified, and the shooting experience is improved. In addition, after focusing is finished, shooting operation can be executed when the fact that the fingers of the user leave the screen is detected, so that the user can check focusing effect and determine whether to focus again according to the focusing effect, and the requirement of the user for focusing is met.
Referring to fig. 10, fig. 10 is a schematic flow chart illustrating a shooting method according to still another embodiment of the present application. The shooting method is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 10, and the shooting method may specifically include the following steps:
step S410: and displaying a shooting interface, wherein the shooting interface comprises a preview area and a shooting button.
In the embodiment of the present application, step S410 may refer to the contents of the foregoing embodiments, and is not described herein again.
Step S420: and responding to the sliding operation of the shooting button, and when the end position of the sliding operation is located in the preview area, detecting the duration of the continuous pressing of the end position as a second duration, wherein the starting time of the second duration is the sliding ending time of the sliding operation.
In the embodiment of the application, the mobile terminal may monitor the sliding track of the sliding operation when the sliding operation of the shooting button is detected, and detect a duration in which the end point position is continuously pressed as the second duration after the sliding operation stops sliding. The starting time of the second time length is the sliding ending time of the sliding operation. That is, after the sliding operation stops sliding, when the finger does not leave the screen, that is, the finger continues to stay at the end position, the length of time that the end position is continuously pressed is detected as the third length of time to determine whether the second length of time is greater than the third length of time. It can be understood that after the user slides the shooting button, the operation of the user when selecting the focus may be slow, and therefore the situation of short stay during sliding may occur, and to avoid the determination that the shooting focus is falsely triggered under the situation, the above second duration may be detected, and it is determined whether the second duration is greater than the third duration; if the second duration is longer than the third duration, the user really stops the sliding operation currently; if the second duration is less than or equal to the third duration, it indicates that the user may only make a short stop during the sliding process, rather than actually stopping the sliding operation. The third time period may be 1 second, 2 seconds, 3 seconds, and the like, and specific values thereof may not be limited.
Step S430: and when the second time length is longer than a third time length, determining a shooting focus according to the end point position.
In this embodiment of the application, after detecting the second duration and determining whether the second duration is greater than the third duration, the mobile terminal may determine whether to execute the determination of the shooting focus and the subsequent steps according to the determination result. If the second time length is larger than the third time length, the sliding operation of the current user is stopped, and therefore the shooting focus can be determined according to the end position. If the second time length is not longer than the third time length, the sliding operation is not stopped by the current user, and the user may continue the sliding operation, so that the shooting focus is determined according to the end point position without being executed temporarily. The third time duration may be 1 second, 2 seconds, and the like, and the specific numerical value may be determined according to the habit of the user.
Step S440: and when the second duration is longer than the third duration and the end position is continuously pressed, displaying indication information for adjusting the specified shooting parameters in an area corresponding to the end position.
In the embodiment of the application, the adjustment of the shooting parameters can be performed in response to the user operation before the shooting is performed, considering that the user may need to perform the adjustment of the shooting parameters before the shooting. Specifically, after it is determined that the second duration is greater than the third duration, and the end point position is continuously pressed, indication information for adjusting the designated shooting parameter may be displayed in an area corresponding to the end point position.
In some embodiments, the area corresponding to the end position may be an area near the end position.

When different pressing force degrees are detected, the displayed current parameter values are correspondingly changed, so that the user can check the currently selected shooting parameter values, and the user can conveniently select the required parameter values. After the fourth time period is exceeded, if it is detected that the pressing force does not change, the parameter value corresponding to the detected pressing force can be used as the parameter value finally selected by the user, and the designated shooting parameter is set as the parameter value corresponding to the detected pressing force.
In still other embodiments, the current parameter value corresponding to the above specified shooting parameter may be displayed in the vicinity of the above end position in the form of indication information. When the mobile terminal is continuously pressed, the mobile terminal can determine the corresponding parameter value according to the duration of the continuous pressing of the terminal position. When the change of the duration is detected, the displayed current parameter value is correspondingly changed, so that the user can check the currently selected shooting parameter value, and the user can conveniently select the required parameter value. After the finger is detected to leave the screen, the subsequent steps can be executed, namely, after focusing is finished, shooting operation is triggered.

Therefore, the user can focus and trigger to complete the shooting operation by sliding the shooting button to the corresponding position of the preview area, the operation of the user is simplified, and the shooting experience is improved. In addition, in order to avoid the situation that the user stops for a short time in the sliding process of the shooting button to falsely trigger the determination of the shooting focus, the determination of the shooting focus and the subsequent steps are executed when the duration that the end point position is continuously pressed is longer than the third duration. And before shooting, indicating information for adjusting the specified shooting parameters is also displayed, so that a user can adjust the parameter values of the specified shooting parameters to meet the shooting requirements of the user.
