Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
A terminal photographing method is applied to a mobile terminal and comprises the following steps: when the mobile terminal is shooting images, detecting whether a plurality of shot objects exist; if yes, determining an image area corresponding to each shot object; selecting three target pixel points which are not on the same straight line from each image area; and determining a shooting focal length according to the target pixel point, and carrying out shooting operation according to the shooting focal length.
As shown in fig. 1, fig. 1 is a schematic flowchart of a terminal photographing method provided in an embodiment of the present application, where the terminal photographing method is applied to a mobile terminal, and a specific flow may be as follows:
s101, when the mobile terminal carries out image shooting, whether a plurality of shot objects exist is detected, if yes, the following step S102 is executed, and if not, the detection is carried out again.
And S102, determining an image area corresponding to each shot object.
In this embodiment, for each shooting, the mobile terminal may detect whether there are a plurality of shooting objects existing in the current shooting area in real time, and if so, find the image area where each shooting object is located.
And S103, selecting three target pixel points which are not on the same straight line from each image area.
In this embodiment, since three points that are not on the same straight line can determine one plane, if it is determined that the photographic object is clear, it can be analyzed whether three points on the photographic plane where the photographic object is located are clear. Specifically, the selection of the three target pixel points may be automatically performed by the mobile terminal, for example, the mobile terminal may randomly select three pixel points from each image region or a key region (for example, a face region), or the selection may also be performed by a user, for example, the user selects one or two image portions in his/her view, and the rest is automatically selected by the mobile terminal.
For example, when the selecting operation is automatically completed by the mobile terminal, referring to fig. 2, the step S103 may specifically include:
and S1031A, judging whether two adjacent image areas have overlapping parts, if so, executing the following step S1032A, and if not, executing the following step S1033A.
S1032A, for each image area, selecting three pixel points which are not on the same straight line from the overlapped part and the non-overlapped part to serve as target pixel points.
S1033A, randomly selecting three pixel points which are not on the same straight line from each image area to serve as target pixel points.
In this embodiment, when there is an overlapping portion, one or two points may be selected from the overlapping portion as a common point, and the remaining points may be selected from the non-overlapping portion, so that accurate positioning of the corresponding shot plane may be ensured, and the number of the selected pixel points may be reduced as much as possible.
For example, referring to fig. 3, assuming that persons a1 to A3 exist in the current shooting area, and overlapping portions m (dotted line areas) exist between a1 and a2, for a1 and a2, one pixel point x may be selected from m, 2 pixel points y1 and y2 are selected from the remaining image corresponding to a1, and 2 pixel points y3 and y4 are selected from the remaining image corresponding to a2, a plane formed by three points x, y1 and y2 is a shooting plane where a1 is located, a plane formed by three points x, y3 and y4 is a shooting plane where a2 is located, and for A3, three points y5, y6 and y7 may be randomly selected as a shooting plane where A3 is located because there is no overlapping portion.
For example, when the selecting operation is completed by the mobile terminal and the user together, referring to fig. 4, the step S103 may specifically include:
S1031B, prompting a user to select a single pixel point;
S1032B, determining the position of a single pixel point selected by a user;
S1033B, selecting residual pixel points from the corresponding image areas according to the positions, and taking the single pixel point and the residual pixel points as target pixel points, wherein each image area comprises three target pixel points which are not on the same straight line.
In this embodiment, the prompt operation may be displayed to the user through the prompt box, and when the prompt box is generated by the mobile terminal, the user may select a pixel point according to a selection mode in the prompt box, for example, a selection mode such as clicking, pressing, and the like.
And S104, determining a shooting focal length according to the target pixel point, and carrying out shooting operation according to the shooting focal length.
For example, the step of "determining the shooting focal length according to the target pixel point" may specifically include:
carrying out focal length adjustment operation on the mobile terminal;
detecting the definition of the target pixel point in the focal length adjusting process;
and when the definition of all target pixel points reaches a preset threshold value, acquiring the current focal length as the shooting focal length.
In this embodiment, the preset threshold may be set according to a resolution of the mobile terminal, and the higher the resolution is, the larger the preset threshold may be. When the target pixel points corresponding to each shot object are selected, focal length debugging can be carried out, the definition of the target pixel points is detected in real time in the debugging process, and the focal length at the moment can be considered as the best shooting focal length until all definition values are higher.
For example, the step of "performing the photographing operation at the photographing focal length" may specifically include:
detecting whether the exposure degree is adjusted by a user;
if so, carrying out photographing operation according to the adjusted exposure and the photographing focal length; storing the adjusted exposure level and the current ambient light brightness in a historical parameter library in a correlated manner;
if not, acquiring the stored exposure corresponding to the current ambient light brightness from the historical parameter library; and carrying out photographing operation according to the photographing focal length and the stored exposure.
In this embodiment, after determining the shooting focal length, the user may be prompted whether to confirm shooting, if the user selects yes, or the shooting focal length does not change within a default time length (for example, 5 seconds), the shutter pressing operation may be performed to take a picture, and before pressing the shutter, an exposure amount required by the shutter needs to be determined, where the exposure amount may be set by the user, for example, the user manually adjusts the exposure amount in a vertical sliding manner on a shooting interface, or the mobile terminal may automatically set according to ambient light, for example, when the user does not adjust the exposure amount, the mobile terminal may automatically analyze a past shooting habit of the user under the current ambient light, and the exposure amount used in the past shooting is used as the exposure amount of the shooting.
It can be known from the above that, the terminal photographing method provided in this embodiment is applied to a mobile terminal, and when the mobile terminal performs image photographing, by detecting whether a plurality of photographed objects exist, if so, determining an image area corresponding to each photographed object, selecting three target pixel points that are not on the same straight line from each image area, then determining a photographing focal distance according to the target pixel points, and performing photographing operation with the photographing focal distance, thereby achieving clear photographing of a plurality of objects without performing multiple times of focusing.
According to the methods described in the above embodiments, the present embodiment will be further described from the perspective of a terminal photographing apparatus, which may be specifically implemented as an independent entity.
Referring to fig. 5, fig. 5 specifically describes that the terminal photographing apparatus provided in the embodiment of the present application is applied to a mobile terminal, and the mobile terminal may include a mobile phone, a tablet computer, a personal PC, and other devices having a photographing function.

In this embodiment, for each shooting, the mobile terminal may detect whether there are a plurality of shooting objects existing in the current shooting area in real time, and if so, find the image area where each shooting object is located.
(3) Selection module 30
And the selecting module 30 is configured to select three target pixel points that are not on the same straight line from each image region.
In this embodiment, since three points that are not on the same straight line can determine one plane, if it is determined that the photographic object is clear, it can be analyzed whether three points on the photographic plane where the photographic object is located are clear. Specifically, the selection of the three target pixel points may be automatically performed by the mobile terminal, for example, the mobile terminal may randomly select three pixel points from each image region or a key region (for example, a face region), or the selection may also be performed by a user, for example, the user selects one or two image portions in his/her view, and the rest is automatically selected by the mobile terminal.
For example, when the selecting operation is automatically completed by the mobile terminal, the selecting module 30 is specifically configured to:

if so, selecting three pixel points which are not on the same straight line from the overlapped part and the non-overlapped part as target pixel points for each image area;
if not, selecting three pixel points which are not on the same straight line from each image area as target pixel points.
In this embodiment, when there is an overlapping portion, one or two points may be selected from the overlapping portion as a common point, and the remaining points may be selected from the non-overlapping portion, so that accurate positioning of the corresponding shot plane may be ensured, and the number of the selected pixel points may be reduced as much as possible.
For example, referring to fig. 3, assuming that persons a1 to A3 exist in the current shooting area, and overlapping portions m exist in a1 and a2, for a1 and a2, one pixel point x may be selected from m, 2 pixel points y1 and y2 are selected from the remaining image corresponding to a1, and 2 pixel points y3 and y4 are selected from the remaining image corresponding to a2, a plane formed by three points x, y1 and y2 is a shooting plane where a1 is located, a plane formed by three points x, y3 and y4 is a shooting plane where a2 is located, and for A3, three points y5, y6 and y7 may be randomly selected as a shooting plane where A3 is located because there is no overlapping portion.
For example, when the selecting operation is performed by both the mobile terminal and the user, the selecting module 30 is specifically configured to:
prompting a user to select a single pixel point;
determining the position of a single pixel point selected by a user;
and selecting residual pixel points from the corresponding image areas according to the positions, and taking the single pixel point and the residual pixel points as target pixel points, wherein each image area comprises three target pixel points which are not on the same straight line.
In this embodiment, the prompt operation may be displayed to the user through the prompt box, and when the prompt box is generated by the mobile terminal, the user may select a pixel point according to a selection mode in the prompt box, for example, a selection mode such as clicking, pressing, and the like.
(4) Photographing module 40
And the photographing module 40 is configured to determine a photographing focal length according to the target pixel point, and perform a photographing operation with the photographing focal length.

and when the definition of all target pixel points reaches a preset threshold value, acquiring the current focal length as the shooting focal length.
In this embodiment, the preset threshold may be set according to a resolution of the mobile terminal, and the higher the resolution is, the larger the preset threshold may be. When the target pixel points corresponding to each shot object are selected, focal length debugging can be carried out, the definition of the target pixel points is detected in real time in the debugging process, and the focal length at the moment can be considered as the best shooting focal length until all definition values are higher.
Further, the photographing module 40 is specifically configured to:
