Example one
As described above, the prior art provides a foldable electronic device, which allows a user to take a self-portrait using a front camera thereof. Usually, a user needs to take a plurality of photos to obtain a self-portrait photo with the optimal effect. In the self-photographing method in the prior art, a user has higher false photographing probability in the self-photographing process of using the folding screen electronic equipment, and the photographing effect of a self-photographing photo is poorer. In order to solve the technical problem, an embodiment of the present invention provides a self-timer method.
The electronic device related to the present invention may be a portable electronic device that further includes other functions, such as a personal digital assistant and/or a music player, such as a mobile phone, a tablet computer, a wearable electronic device (e.g., a smart watch) with a wireless communication function, a bank system, an attendance system, an access control system, and other mobile terminals. Exemplary embodiments of portable electronic devices include, but are not limited to, portable electronic devices that carry an IOS, Android, Microsoft, or other operating system. The portable electronic device may also be other portable electronic devices such as a Laptop computer (Laptop) or the like. It should also be understood that in other embodiments, the electronic device may not be a portable electronic device, but may be a desktop computer.
For example, fig. 1 shows a schematic structural diagram of an electronic device (e.g., a mobile phone). The electronic device is provided with a flexible display screen which can bend a first screen 10 and a second screen 20, wherein a camera unit 12 is arranged below the first screen.
The first screen and the second screen can be folded relatively, and in practical application, a user can set the first screen and the second screen to be placed at a preset angle so that the user can operate different applications on the two screens. For example, when the user operates the electronic device to take a self-portrait, the camera unit below the first screen may be opposite to the face of the user to capture an image of the user. Because the included angle of the first screen and the second screen can be set by the user at will, the relative angle between the camera shooting unit and the face of the user has various conditions during self-shooting, and the user can hardly judge which angles have the best self-shooting effect through experience.
For example, one preferred selfie angle is in the range of 30 to 45 degrees obliquely above the face. When a user takes a picture by himself, the electronic equipment needs to be lifted, and the camera shooting unit is higher than the human face. As shown in fig. 2, since the first screen is in a bent state relative to the second screen, the relative angle between the camera unit and the face is difficult to be accurately controlled within a range of 30 degrees to 45 degrees obliquely above the face.
As shown in fig. 2, the included angle between the first screen and the second screen is about 90 degrees, and the camera unit 12 serves as a front camera to shoot a human face downwards.
The camera unit 12 may be disposed below a transparent region of the first screen 10, for example, and captures an imaging image through the transparent region of the display screen in the display region by using an imaging component.
In combination with the above application scenarios, the following describes the technical solution of the embodiment of the present invention in detail.
Fig. 3 is a flowchart of a self-timer method according to an embodiment of the present invention, where an execution subject of the method may be the electronic device. As shown in fig. 3, the method may include the steps of:
step S301: and receiving a self-photographing instruction and determining a preset self-photographing angle.
Step S302: and adjusting the bending angle of the first screen relative to the second screen according to a preset self-timer angle value, so that the first screen faces a shooting object.
Step S303: and adjusting the shooting angle of the camera shooting unit to the preset self-shooting angle value based on the bending angle of the first screen relative to the second screen.
Step S304: and controlling the camera shooting unit to shoot.
Before step S301, the method further includes: and determining the preset self-timer angle value based on historical self-timer image information.
For example, the user operates the electronic device to perform a plurality of self-timer shots, and self-timer image information is stored in the history image information base.
First, a face image with the best effect in a self-portrait image is identified. On one hand, the face image with the optimal self-photographing effect can be calculated through the face recognition technology. The face recognition technology can detect and locate faces in a shooting scene, for example, face detection based on geometric features, and determines that the faces are composed of parts such as eyes, noses, mouths, and jaws, and the shapes, sizes and structures of the parts are different from one another so that every face in the world is different from one another, and therefore geometric description of the shapes and structural relationships of the parts can be used as important features of face recognition. On the other hand, the user can browse the historical images one by one and select the face image with the optimal self-photographing effect.
Secondly, calculating a self-timer angle corresponding to the face image with the optimal self-timer effect, and storing the self-timer angle as a preset self-timer angle. The preset self-timer angle may be an angle value or a series of angle values.
In step S303, the step of adjusting the shooting angle of the image capturing unit to the preset self-timer shooting angle value includes:
acquiring the normal vector direction of the first screen;
controlling the shooting angle of the shooting unit to be adjusted within a threshold angle range taking the normal vector direction of the first screen as the center;
and setting the shooting angle of the camera shooting unit as a preset self-shooting angle.
FIG. 4 is a diagram illustrating a first screen normal vector of an electronic device according to an embodiment of the present invention. Specifically, a gyroscope sensor is arranged in the first screen, and the electronic device can acquire the normal vector direction of the first screen through the gyroscope sensor. Fig. 5 is a schematic diagram of a geographic coordinate system ox established based on a gyro sensor according to an embodiment of the present applicationtytztIs located at the centre point, x, of the gyro sensortThe axis points along the local latitude line to east, ytThe axis indicates north, z along the local meridiantThe axis pointing along the local geographical vertical and being in line with xt、ytAnd forming a right-hand rectangular coordinate system. Wherein x istAxis and ytThe plane formed by the axes is the local horizontal plane, ytAxis and ztThe plane formed by the axes is the local meridian plane. Suppose z is the normal vector of the first screen1And (4) showing. The normal vector z of the first screen can be determined from the pointing provided by the gyro sensor1。
Specifically, the photographing angle of the photographing unit 12 may be in the normal vector direction z of the first screen1And adjusting the central threshold angle range phi, and further setting the shooting angle of the camera shooting unit as a preset self-shooting angle.
In step S304, the method further includes a step of controlling the image capturing unit to adjust the focus range by the electronic device. In one example, the image information of the shooting object is previewed by the shooting unit, the focusing range of the shooting unit is set to be the face range of the shooting object, and the shooting unit is controlled to shoot. In another example, a preset focusing range is obtained based on historical self-timer image information, the focusing range of the camera shooting unit is set as the preset focusing range, and the camera shooting unit is controlled to shoot. The preset focusing range can be determined by the self-timer effect optimal image in the historical self-timer image information. For example, the sharpest range in the image identified by the image processing algorithm that is the most excellent in self-timer effect is determined as the preset focus range.
In the embodiment of the invention, a user can place the electronic equipment on a desktop or hold the electronic equipment in a hand, a self-photographing mode is started, the electronic equipment can automatically adjust the bending angle of the first screen according to a preset self-photographing angle, then automatically adjust the photographing angle and the focal length of the photographing unit based on the normal vector direction of the first screen, and the photographing unit automatically finishes photographing. The mistake probability of taking a picture in the folding screen electronic equipment auto heterodyne in-process can be reduced, the shooting effect of auto heterodyne photo is improved.
In the embodiment of the invention, the self-timer image of the user is stored, the optimal self-timer image is automatically calculated, and the preset self-timer angle is calculated, so that the method and the device are suitable for single-person shooting or multi-person shooting.
