Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A photographing method and apparatus of a mobile terminal according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 2 is a flowchart of a photographing method of a mobile terminal according to one embodiment of the present invention. It should be noted that the present embodiment is exemplified in the case where the photographing method of the mobile terminal is configured as a photographing apparatus of the mobile terminal. The embodiment of the invention can be applied to the process that the user shoots the portrait to be shot by using the mobile terminal. The mobile terminal may be a hardware device with various operating systems, such as a smart phone, a tablet computer, a personal digital assistant, and an electronic book, which is not limited thereto.
As shown in fig. 2, the photographing method of the mobile terminal may include:
s210, predicting the overall length of the portrait to be shot, and acquiring the first size of the portrait to be shot according to the overall length.
Specifically, the face recognition of the portrait to be photographed can be performed to obtain the size and the position relationship of the face, then the overall length of the portrait to be photographed can be predicted according to the size of the face and the preset human body proportion, and finally the first size of the portrait to be photographed can be obtained according to the overall length. For a description of a specific implementation process, reference may be made to the detailed description of the following embodiments.
In the embodiment of the present invention, the to-be-photographed portrait may be a portrait that a user needs to photograph using a mobile terminal. For example, the portrait may be an image of the user collected when the user performs a self-photographing mode through a front camera of the mobile terminal, or may be an image collected when the user photographs others through a rear camera of the mobile terminal.
And S220, judging whether the portrait to be shot meets a preset condition according to the overall length and the first size.
In an embodiment of the present invention, the preset condition may be preset by a built-in program of the mobile terminal, where the preset condition may be, for example, that a ratio of a length of the portrait to be photographed in a screen size of the mobile terminal to an overall length of the portrait to be photographed reaches a preset threshold, and for example, that the ratio of the overall length of the portrait to be photographed to the screen size of the mobile terminal reaches the preset threshold, where the preset threshold may be, for example, a ratio, and is not limited thereto.
It can be understood that the photographing method of the mobile terminal according to the embodiment of the present invention is to stretch the legs of the portrait to be photographed, so that the stretching process may be performed only when the legs of the portrait to be photographed have a sufficient length in the screen of the mobile terminal, and when the length of the portrait to be photographed in the screen size of the mobile terminal occupies a small proportion of the overall length of the portrait to be photographed, if the legs of the portrait to be photographed are stretched, the stretching meaning of the legs may not be great because the legs of the portrait to be photographed in the screen size of the mobile terminal are small, and the opposite effect may be performed, for example, the portrait has a severely deformed proportion. Therefore, whether the proportion value of the length of the portrait to be shot in the size of the screen of the mobile terminal to the whole length of the portrait to be shot meets the preset condition or not can be judged in advance, and when the proportion value meets the preset condition, the target rotation angle can be conveniently acquired according to the first size of the portrait to be shot subsequently.
Specifically, it may be determined that the first size of the portrait to be photographed occupies a proportion of the overall body length, and it may be determined whether the portrait to be photographed satisfies a preset condition according to the proportion, for example, when the proportion is greater than a certain threshold, it may be determined that the portrait to be photographed satisfies the preset condition.
As an example, as shown in fig. 3, the specific implementation process of determining whether the portrait to be photographed satisfies the preset condition according to the overall body length and the first size may include the following steps:
and S310, calculating a proportion value of the first size of the portrait to be shot occupying the whole body length.
For example, the predicted overall length of the person to be photographed is, for example, 12.5cm, and the first size of the acquired person to be photographed is, for example, 10.5cm, so that the proportion of the first size of the person to be photographed to the overall length is 10.5cm/12.5cm — 84%.
S320, judging whether the proportion value is larger than or equal to a preset threshold value.
In the embodiment of the present invention, the preset threshold may be preset by a built-in program of the mobile terminal, or the preset threshold may also be set by a user, which is not limited thereto.
Optionally, the preset threshold is, for example, 70%, it is determined whether a ratio of the first size of the portrait to be photographed to the overall length reaches the preset threshold, and when the ratio reaches the preset threshold, the step of obtaining the target rotation angle according to the first size is performed, that is, the step S230 is performed.
It can be understood that, in the embodiment of the present invention, when the determination ratio value is smaller than the preset threshold, it may be determined that the to-be-photographed portrait does not satisfy the preset condition, and exit may be ended at this time, that is, the camera module is no longer controlled to rotate according to the target rotation angle, but the to-be-photographed portrait may be photographed according to the normal photographing mode, that is, the leg portion of the to-be-photographed portrait is no longer stretched in the photographing mode at this time.
S330, if the proportional value is larger than or equal to the preset threshold value, judging that the portrait to be shot meets the preset condition.
For example, taking the proportional value of the first size occupying the entire body length calculated in step S310 as 10.5/12.5 — 84%, when the preset threshold value is, for example, 70%, it can be understood that the proportional value reaches the preset threshold value, which indicates that the leg portion of the portrait to be photographed can be stretched, that is, it can be determined that the portrait to be photographed satisfies the preset condition.
And S230, when the portrait to be shot meets the preset condition, acquiring a target rotation angle according to the first size. As an example, the first size of the portrait to be photographed can be understood as the length of the portrait to be photographed in the size of the screen of the mobile terminal.
In order to improve usability and feasibility and improve the result of acquiring the first size of the portrait to be photographed, in an embodiment of the present invention, as shown in fig. 4, the specific implementation process of predicting the overall length of the portrait to be photographed and acquiring the first size of the portrait to be photographed according to the overall length may include the following steps:
and S410, identifying the face image of the portrait to be shot, and acquiring a second size and a position relation of the face image in the screen size of the mobile terminal.
For example, a face image of a person to be photographed may be recognized by a face recognition technique, and a size and a positional relationship of the face image with respect to a screen size of the mobile terminal may be acquired.
And S420, predicting the overall body length of the portrait to be shot according to the second size of the face image in the screen size of the mobile terminal and the preset human body proportion.
Specifically, the overall length of the portrait to be shot can be calculated according to the preset human body proportion according to the second size of the face image in the screen size of the mobile terminal. The preset human body proportion can be an empirical value, or a human body proportion value obtained by referring to the work of Viteluweiren depicted by DaVinci.
And S430, acquiring the length of the portrait to be shot in the screen size of the mobile terminal according to the overall length and the position relation of the face image in the screen size of the mobile terminal, and taking the length as the first size of the portrait to be shot.
For example, fig. 5 is a schematic diagram of a face recognition result of a mobile terminal in an embodiment of the present invention, as shown in fig. 5, when a face image B of a person to be photographed is recognized, a second size D and a position relationship of the face image B in a screen size C of the mobile terminal may be obtained, then, an overall length H of the person to be photographed may be predicted according to the second size D of the face image B in the screen size C of the mobile terminal and a preset body ratio, and finally, a length W of the person to be photographed in the screen size C of the mobile terminal may be obtained according to the overall length H and the position relationship of the face image B in the screen size C of the mobile terminal, where the length W is a first size of the person to be photographed. Therefore, when the body length W/the whole body length H reaches a preset threshold value, the shot portrait can be judged to meet the preset condition.
When the portrait to be shot meets the preset conditions, the target rotation angle can be obtained according to the first size of the portrait to be shot, so that the camera module is controlled to rotate according to the target rotation angle subsequently. As an example, the target rotation angle may be obtained according to a first size of a portrait to be photographed and a preset model. In an embodiment of the present invention, the preset model may be as follows:
A＝(Amax/Lmax)*L (1)
wherein A is the target rotation angle, AmaxThe maximum rotation angle L of the camera modulemaxIn order to achieve the maximum body length of the portrait to be shot after the leg of the portrait to be shot is stretched in the screen size of the mobile terminal, L is the first size of the portrait to be shot.
For example, the maximum rotation angle A that a known camera module can rotatemaxThe maximum body length L of the portrait to be shot after the leg of the portrait to be shot in the screen size of the mobile terminal is stretchedmaxAnd the first size L of the portrait, the target rotation angle a can be calculated by the above equation (1).
In this embodiment, when the proportional value that occupies whole body length through the first size at the portrait of waiting to shoot is greater than or equal to and predetermines the threshold value, judge that the portrait of waiting to shoot satisfies preset condition, can acquire target rotation angle according to first size and preset model this moment, can calculate the rotatory angle of camera module accurately, the part of the portrait of waiting to shoot passes through linear distortion's control, in order to treat that the shank of the portrait of shooting carries out tensile processing, in order to beautify the portrait, make the shank and the health of portrait seem longer more, promote user's shooting experience.
And S240, driving the camera module to rotate according to the target rotation angle through the MEMS OIS.
In an embodiment of the present invention, the camera module may include, but is not limited to, a lens, a motor, a sensor, and the like. In addition, in an embodiment of the present invention, the mobile terminal may have a micro electro mechanical optical anti-shake system MEMS OIS, wherein the micro electro mechanical optical anti-shake system MEMS OIS may be connected to the camera module.

In this example, the MEMS OIS may include a plurality of pairs of fixed and movable electrodes, each pair for moving the camera module along a different angle in the same plane. From this, can realize carrying out the mobility control of different angles to the camera module.
And S250, shooting the to-be-shot portrait according to the rotated camera module so as to stretch the legs of the to-be-shot portrait in the shooting process.
Specifically, can adopt the camera module after the rotation to treat and shoot the portrait for the shank of treating to shoot the portrait is closer to the camera module, and facial remoter is farther away from the camera module, in order to form nearly big-end-up's linear perspective principle, like this, adopts the camera module after the rotation to treat to shoot the portrait, can realize can treating the shank of shooting the portrait and carry out tensile processing at the shooting in-process.
