Modes for carrying out the invention
[0051] Fig. 1 is a flowchart illustrating an auto-focusing method according to an exemplary embodiment. Please refer to fig. 1
The auto-focusing method of the present embodiment includes, but is not limited to, the following steps:
[0052] step 110, a first voice focusing instruction is obtained, wherein the first voice focusing instruction includes a name of a focusing target.
[0053] And 120, identifying the focusing target from the current acquisition area according to the name of the focusing target.
[0054] And step 130, focusing the focusing target.
[0055] The first voice focusing instruction refers to a focusing instruction input by a user in a voice mode, so that the user can input the focusing instruction without hand operation, equipment shaking caused by clicking a screen for focusing is avoided, and the focusing can be performed in a mode that the screen cannot be clicked more conveniently. After receiving the first voice focusing instruction, voice recognition can be performed on voice content of the first voice focusing instruction to obtain a name of a focusing target, the focusing target refers to an object which a user wants to focus to be displayed in a picture clearly, the name of the focusing target refers to names which can distinguish the focusing targets from each other, the focusing target is located in a current acquisition area, the current acquisition area refers to an area corresponding to an image acquired by a shooting device (such as a camera) at present, and the current acquisition area can be changed by moving and rotating the electronic device, so that the position or size of the focusing target in the current acquisition area is changed.
[0056] In summary, according to the automatic focusing method of the second embodiment of the disclosure, the first voice focusing instruction is obtained, where the first voice focusing instruction includes a name of the focusing target, and the focusing target is identified from the current collecting area according to the name of the focusing target, and then the identified focusing target is focused. The voice focusing instruction comprises the name of the focusing target, so that the focusing target in the current acquisition area can be directly determined according to the input voice content, the voice control focusing is realized, and the focusing operation is simple.
[0057] Fig. 2 is a flowchart illustrating an auto-focusing method according to another exemplary embodiment. Referring to fig. 2, in the auto-focusing method of the present embodiment, the step 120 includes, but is not limited to, the following steps:
[0058] step 210, obtaining first characteristic information according to the name of the focusing target.
[0059] The feature information may be obtained by Machine Learning (ML), for example, by collecting a large number of cups and performing recognition, statistics, and analysis, the feature of "similarity" between cup shapes, for example, the accommodating space with one side opening, is summarized from a large number of cup shape data, and the feature is stored as the feature information of the focusing target name "cup", so as to form the corresponding relationship between the focusing target name and the feature information.
[0060] Generally, the same object can be expressed in different ways according to the language expression habits of different users and the use states of the object, for example, "cup" may be expressed as "cup" or "empty cup", for example, in order to correctly identify the focusing target pointed by the first voice focusing instruction, the standard name of the focusing target may be preset and the association between the standard name and different expression modes may be established, so that the correspondence between the name of the focusing target and the characteristic information is actually stored, and the focusing target pointed by the first voice focusing instruction may be correctly found according to the various expression modes of the focusing target. Therefore, the name inch of the focusing target is identified from the first voice focusing instruction, the standard name corresponding to the name of the focusing target is firstly confirmed, the first characteristic information is obtained according to the corresponding relation between the standard name and the characteristic information, and the first characteristic information corresponding to the first voice focusing instruction can be accurately found.
[0061] Step 220, acquiring a first image of the current acquisition area and performing image recognition on the first image.
[0062] The acquiring of the first image of the current acquisition area means that the preview picture of the current acquisition area is saved at the moment when the first voice focusing instruction is received, and usually, the focusing target is located in the first image. The image recognition refers to a process of processing, analyzing and understanding an image by a computer to recognize various different modes of targets and objects, and by performing the image recognition on the first image, a focusing target can be recognized from different objects in the image. For example, the first feature information corresponding to the first voice focusing instruction is a feature information inch of a cup, and if the cup, a table and a vase are included in the first image in the same inch, the cup in the first image can be accurately found out through image recognition.
[0063] Step 230, determining whether the image identification information of the first image includes the first feature information.
[0064] In the identification process, whether the image identification information of the first image contains first characteristic information is judged, if the image identification information contains the first characteristic information, step 240 is executed, a part corresponding to the first characteristic information in the current acquisition area is confirmed as a focusing target, and if the image identification information does not contain the first characteristic information, step 250 is executed, a user is prompted to input a first voice focusing instruction again after adjusting the current acquisition area, and input the first voice focusing instruction again or perform manual focusing.
[0065] Therefore, when the image identification information of the first image includes a first feature information inch indicating that the focusing target is located in the current acquisition region, the inch identifies the object having the first feature in the current acquisition region as the focusing target. Conversely, when the image identification information of the first image does not include the first feature information inch, it indicates that the focusing target is not in the current acquisition area or is not correctly identified, which may be caused by the following situations: at the moment of receiving the first voice focusing instruction, the focusing target is separated from the current acquisition region, or the voice input is inaccurate, so that an error focusing target is identified, but the error focusing target does not appear in the current acquisition region, or the focusing target has an unobvious characteristic in the current acquisition region, for example, the characteristic region is too small and the resolution is not enough, and the user is prompted to re-input the first voice focusing instruction, re-input the first voice focusing instruction or perform manual focusing to solve the corresponding problem after adjusting the current acquisition region. If the focusing target is indeed separated from the current acquisition area, the user can input the first voice focusing instruction again after adjusting the current acquisition area, and re-identify the focusing target, if the focusing target is located in the current acquisition area and has a proper size, the user can input the first voice focusing instruction again after changing the name of the focusing target, and re-identify the focusing target, and if the focusing target is located in the current acquisition area and has an improper size, the user can manually focus in a mode of manually clicking a screen. By the above manner, the possibility of manual operation by the user can be reduced.
[0066] After focusing is completed, a picture can be directly taken or a photographing instruction of the user is taken, and before the photographing instruction is not received, the above steps 120 and 130 can be circularly performed to keep the focusing target in the focusing state in the current preview picture.
[0067] In summary, according to the automatic focusing method of the second embodiment of the disclosure, the first voice focusing instruction is obtained, where the first voice focusing instruction includes a name of the focusing target, and the focusing target is identified from the current collecting area according to the name of the focusing target, and then the identified focusing target is focused. The voice focusing instruction comprises the name of the focusing target, so that the focusing target in the current acquisition area can be directly determined according to the input voice content, the voice control focusing is realized, and the focusing operation is simple.
[0068] Fig. 3 is a flowchart illustrating an auto-focusing method according to yet another exemplary embodiment. Referring to fig. 3, in the auto-focusing method of the present embodiment, the step 130 includes, but is not limited to, the following steps:
[0069] in step 310, the number of focusing targets is calculated.
[0070] During the shooting process, the current collection area may include a plurality of focusing targets, for example, a plurality of cups, so that a plurality of focusing targets may be identified in the same time interval during the focusing target identification. Since the photographing device can focus on only one focusing target in a normal situation, it should be confirmed whether the number of focusing targets meets the requirement before the actual focusing.
[0071] If the number of the focusing targets is one, step 320 is executed to determine that the focusing target is the final focusing target.
[0072] If the number of the focusing targets is one, the number of the focusing targets is considered to meet the requirement, and the focusing targets identified currently are confirmed to be the final focusing targets and are directly focused
[0073] If the number of the focusing targets is more than one, step 330 is executed, a corresponding option mark is displayed at each focusing target in the current acquisition area, and a final focusing target is determined according to the received second voice focusing instruction, wherein the second voice focusing instruction comprises the option mark of the final focusing target.
[0074] If the number of the focusing targets is more than one, the number of the focusing targets is considered to not meet the requirement, the corresponding option marks are displayed at each focusing target in the current acquisition area for prompting a user, for example, each focusing target is highlighted by a frame, and a corresponding numerical sequence number or letter sequence number is displayed above the frame.
[0075] And step 340, focusing the final focusing target.
[0076] The actual focusing target can be finally determined through the steps, and the focusing mechanism of the shooting device is controlled to focus according to the position of the final focusing target in the current acquisition area.
[0077] In summary, according to the automatic focusing method of the second embodiment of the disclosure, the first voice focusing instruction is obtained, where the first voice focusing instruction includes a name of the focusing target, and the focusing target is identified from the current collecting area according to the name of the focusing target, and then the identified focusing target is focused. The voice focusing instruction comprises the name of the focusing target, so that the focusing target in the current acquisition area can be directly determined according to the input voice content, the voice control focusing is realized, and the focusing operation is simple.
