Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
First embodiment
Referring to fig. 1, a method for controlling photographing according to a first embodiment is applied to a mobile terminal, and the method includes:
In this step, the gesture input area is a display area capable of shooting gesture input of the user, that is, when the user takes a picture, gesture action input is performed in the gesture input area in the current preview interface.
Specifically, the gesture input area may be a predetermined area in the image preview interface, and before photographing, the predetermined area is determined and stored by a user in advance, that is, the gesture input area during gesture input during photographing can be determined; in addition, the gesture input area can also be an area where the hand of the user is located when the user takes a picture at present, which is automatically detected, and the gesture input area is identified and determined by identifying the hand image information displayed in the image preview interface.
Preferably, the photographing control method of the present invention is applied to operation control during self-photographing, and the image preview interface in step 101 is an image preview interface during a self-photographing mode.
Specifically, the detected gesture includes whether the hand presenting state meets a preset state and whether the motion of the hand state meets a predetermined track motion. The hand presenting state for performing the gesture input may be a state in which one finger, a plurality of fingers or a state in which one finger is clenched as a fist, and the predetermined trajectory motion may be a movement in one direction. The mobile terminal can pre-store image information of preset hand states and information of corresponding preset track actions, can store a plurality of image information of preset hand states and corresponding information of a plurality of preset track actions, and forms a plurality of different preset gestures through different preset hand states and different preset track actions, wherein the different preset gestures correspond to different photographing operation instructions.
And 103, if the preset gesture exists, executing a photographing operation instruction corresponding to the preset gesture.
And when the preset gesture exists in the current image preview interface, determining that a user inputs an instruction for inputting an action for current photographing, and executing a corresponding photographing operation instruction according to the corresponding relation between the preset gesture and the preset operation instruction. For example, when it is detected that the user has made an upward movement motion of extending one finger in the image preview interface, where the one finger is in a hand state of a gesture, and a predetermined trajectory motion is performed in the upward movement motion, the upward movement motion of the one finger is stored in the mobile terminal in advance, and the motion can be used to adjust the exposure parameter of the current self-timer shooting to the increasing direction, that is, when there is a corresponding relationship with the operation instruction for adjusting the output exposure parameter to the increasing direction, the operation instruction for increasing the exposure parameter is executed.
Through the steps 101 to 103, when a user performs self-shooting, particularly uses a selfie stick to perform self-shooting, although the mobile terminal is arranged at one end of the selfie stick far away from the handheld end, when the shooting mode or parameters of the mobile terminal are adjusted, the mobile terminal does not need to be held close, only needs to be held by one hand and make corresponding predetermined track actions by the other hand according to the corresponding relation between the operation instructions to be input and the preset gestures under an image preview interface, and the operation instruction to be executed can be executed by the mobile terminal, so that the operation process of self-shooting is simple and convenient, and the problems that the mobile terminal needs to be moved close for multiple times when self-shooting is performed, the shooting process is complicated, and the shooting parameters need to be adjusted repeatedly are avoided.
Second embodiment
Referring to fig. 2, the method for controlling photographing according to the second embodiment includes:
In this step, the gesture input area is a display area capable of shooting gesture input of the user, that is, when the user performs gesture input, image information input by the gesture can be displayed in the gesture input area in the current preview interface, so that when the mobile terminal detects whether the current user performs gesture input or not to perform photographing operation, only the gesture input area determined needs to be detected, and an effect of improving the detection speed is achieved.
The gesture input area may be a pre-designated area in a display interface of the mobile terminal.
Preferably, in step 201, the step of determining a gesture input area in the image preview interface includes:
detecting a face image area in an image preview interface;
setting one area out of the face image area in the image preview interface as the gesture input area.
In this way, one of the regions other than the face image region in the image preview interface can be set as the gesture input region.
As shown in fig. 3, since a face image is usually present in the self-timer image, in order to prevent the head image from overlapping with the display portion at the time of gesture input, the gesture input area 1 for gesture input to control the photographing operation in the operation method according to the present invention is set as one of the areas other than the face image area 2.
By adopting the gesture input area determining mode, the face image and the hand image displayed in the image preview interface can be obviously divided into areas, so that the action performed by the hand can be clearly detected, and the effect of increasing the recognition rate is achieved.
Specifically, when detecting a face image region in the image preview interface, the colors of the image displayed in the image preview interface are first distinguished, and a region having a large contrast with skin color, such as a sky region or a clothing region (having a color such as black, red, or blue, and having a large contrast with skin color), is detected, and this region having a large contrast with skin color is set as a gesture input region.
In addition, to further facilitate the distinction of the hand images, it is preferable that one of the regions having a single color other than the face image region in the image preview interface be set as the gesture input region 1.
In the control method according to the present invention, the above-mentioned method for detecting a face image region in an image preview interface should be a technique well known to those skilled in the art, and this part is not a research focus of the present invention and will not be described in detail herein.
And 203, outputting a prompt message for prompting the user to perform gesture input in the gesture input area.
Specifically, as shown in fig. 3, a prompt message "place handle in this area" may be displayed inside the determined gesture input area 1, where the displayed area is a gesture input area for prompting the user to perform a motion input with a hand inside the currently displayed demarcated area to perform a self-timer control operation.
That is, whether the preset hand state exists or not is detected to act in a preset track.
Through the above steps 201 to 204, after the gesture input area is determined in the current image preview interface, when it is determined whether the gesture input of the user exists, it is only required to detect whether the preset gesture input exists in the determined gesture input area.
In step 205, if a preset gesture exists, a photographing operation instruction corresponding to the preset gesture is executed.
That is, if the preset hand state acts in the preset track, the photographing operation instruction corresponding to the preset track action of the preset hand state is executed.
When it is determined that a preset track action of a preset hand state exists in a gesture input area determined in a current image preview interface, determining that a user inputs an action input instruction for taking a current self-timer picture, and executing a corresponding picture taking operation instruction according to a corresponding relation between a preset track action of the preset hand state and a preset operation instruction.
In the control method according to the second embodiment, when a user uses a selfie stick to perform self-photographing, the mobile terminal may prompt the user to perform gesture input in an area defined in the image preview interface, so that the mobile terminal can photograph a hand image and make a corresponding predetermined trajectory action in a preset hand state in the gesture input area determined in the current image preview interface, that is, the mobile terminal can execute a photographing operation instruction to be executed, thereby enabling the self-photographing operation process to be simple and convenient.
Third embodiment
A control method according to a third embodiment, referring to fig. 4, the control method includes:
In this step, according to the second embodiment, a gesture input area may be automatically defined in the image preview interface, and the user may be instructed to perform gesture input in the defined gesture input area, and determine whether a hand image exists in the gesture input area.
In addition, a position area where the hand image is located may be determined as the gesture input area by automatically detecting the position of the hand image.
In this embodiment, when the user performs the action input by using the hand, the state of the hand may be a state in which one finger, two fingers, three fingers, or the like is extended, or a state in which the hand is clenched as a fist, different states are presented by setting the hand in advance, and different operation instructions are predetermined during the self-photographing in the predetermined trajectory action.
Further, by this step, it is determined whether the user is performing gesture input. For example, when a state that a user stretches out one finger is preset as gesture input, when a hand image of the user is detected in the image preview interface as a state that the user stretches out one finger, the user is determined to be performing gesture input; when the state that the user closes the fist is scheduled to be in the gesture input state, when the state that the hand image of the user is in the fist closing state is detected in the image preview interface, the user is determined to be in the gesture input state.
Of course, the hand state predetermined for gesture input may not be limited to one type, and may be respectively used for operation instructions corresponding to different functions. When the hand image exists in the image preview interface, the detected hand image is matched with the pre-stored different hand state image information corresponding to different operation instructions, so that whether gesture input is performed in the image preview interface can be determined.
Through the step, whether the current movement mode of the user for gesture input through the hand meets the preset track action or not is determined, wherein the preset same hand state can comprise a plurality of preset track actions which respectively correspond to different adjustment modes when the same operation function is executed.
When it is determined through the above step 402 that the hand state of the user in the image preview interface conforms to the predetermined state, recording an initial position of the hand in the display interface, determining a movement trajectory of the hand according to a change in position of the hand in the display interface in each frame image within a predetermined time period, comparing the determined movement trajectory information of the hand with information of a plurality of predetermined trajectory actions, and when one of the plurality of predetermined trajectory actions is matched, determining that a preset gesture exists in the image preview interface and the corresponding operation instruction is matched.
And step 404, determining a photographing operation function required to be executed by the operation instruction according to the hand state of the preset gesture.
The photographing operation function refers to an instruction for executing different controls in a current photographing mode. For example, the photographing operation functions include photographing mode switching, exposure parameter adjustment, brightness adjustment, photographing execution, and the like.
In the third embodiment of the present invention, different predetermined hand states can be preset to correspond to different photographing operation functions, that is, different photographing operation functions can be corresponding to different hand states; and when the same hand state acts along different preset tracks, different preset gestures are formed and are used for executing different adjusting directions under the corresponding photographing operation function.
For example, when the hand is in a fist state, the switching function is used for indicating the mode switching operation when self-shooting is performed, and the switching modes which can be included include normal shooting, beauty, panorama and night scene; when the hand moves upwards in a fist state, the switching sequence for indicating that the switching modes are executed is forward adjustment in sequence; when the hand moves downwards in a fist shape, the switching sequence for indicating that the switching modes are executed is sequentially adjusted backwards.
When the hand is in a state of extending a finger, the operation function for adjusting the exposure parameter when executing the current self-photographing is represented; when the hand moves upwards in a state of extending one finger, the hand is used for indicating that the exposure parameter is adjusted towards the increasing direction; when the hand appears to move downwards in a state of one finger, the method is used for indicating that the exposure parameter is adjusted towards the decreasing direction.
Similarly, according to the above manner of jointly determining through different hand states and different predetermined trajectory actions, the photographing operation instruction to be executed when the gesture is input can be determined.
And step 406, executing the photographing operation instruction according to the determined photographing operation function and the corresponding adjusting direction.
According to the steps, when the action input of the user for self-timer shooting through hand action is determined, the shooting operation instruction required to be executed can be determined according to the determined shooting operation function and the corresponding adjusting direction, so that the corresponding operation instruction is executed.
By adopting the control method of the third embodiment of the invention, when a user uses the selfie stick to carry out self-shoot, and when the shooting mode or parameters of the mobile terminal are adjusted, the mobile terminal can execute the operation instruction to be executed only by holding the selfie stick with one hand and carrying out corresponding gesture input with the other hand under the image preview interface, so that the operation process of self-shoot is simple and convenient.
Preferably, in the first to third embodiments of the control method, when the mobile terminal is currently located in the photographed image preview interface, before determining the gesture input area in the image preview interface, the control method further includes:
displaying a touch button for selecting gesture input in the image preview interface;
and if the fact that the user clicks the touch button is detected, determining a gesture input area in the image preview interface.
Then, detecting whether a preset gesture exists in the gesture input area or not,
and if the preset gesture exists, executing a photographing operation instruction corresponding to the preset gesture.
The method comprises the steps of displaying a touch button for enabling a user to perform gesture input in an image preview interface before determining a gesture input area in the image preview interface, and starting operation control for performing photographing control through gesture input after detecting that the user clicks the touch button, so that the control method is started in response to an instruction of the user, and the function can be closed when not needed, thereby increasing the use flexibility.
