Background

With the requirement of users on the aesthetic appearance of mobile phones, the design trend of mobile phones is gradually developing towards lightness and thinness, and manufacturers will design the thickness of the camera device to be thinner and thinner in order to meet the development trend. For example, as shown in fig. 1a, the camera device includes two parts, a lens module and an image sensor (or a light sensing device). The lens module maps the incident light 1 and light 2 on the image sensor to form a shot image. The distance between the optical centers O of the light rays 1 and 2 and the image sensor is an image distance v, which can determine the size of the field angle. Specifically, in the case of keeping the distance between the object to be photographed and the image sensor constant, the larger the image distance v, the larger the image of the object to be photographed that is mapped on the image sensor; the smaller the image distance v, the smaller the image of the subject. As shown in fig. 1b, when the image distance between the lens module and the image sensor is short, the adjustment range of the field angle is limited to a small range. When the image distance between the camera module and the image sensor is far enough, the visual angle can be adjusted spatially, so that the large-range optical zooming is realized.

Wherein the closed cavity 60 is accommodated within the first portion 10 and is located between the lens module 40 and the light sensing device 50. Taking fig. 2a, 2b or 3 as an example, the lens module 40 is disposed on the outer side 101 of the first portion 10 and connected to one end of the closed cavity 60. Specifically, the lens module 40 may be directly connected to one end of the closed cavity 60 to form a closed space, or may be connected to one end of the closed cavity 60 through a connecting member, which may be made of some transparent materials, to achieve a closed effect.

The other end of the closed cavity 60 is connected to the photosensitive device 50, and the closed cavity 60 is surrounded by a closed transparent and opaque material. The structure can ensure that incident light enters the photosensitive device 50 from the lens module 40 through the closed cavity 60, and ensure the normal operation of the shooting function. In addition, the structure can prevent the leakage of incident light, thereby improving the imaging quality.

Alternatively, in a specific embodiment, the photosensitive device 50 may be disposed on the inner side surface 102 of the first portion 10, so that the length of the closed cavity 60 is the largest, and the distance between the lens module 40 and the photosensitive device 50 is the largest. Illustratively, as shown in fig. 2a and 4a, wherein fig. 4a is a front view (front view) of the first portion 10 shown in fig. 2 a. When the photosensitive device 50 is disposed on the inner side surface 102 of the first portion 10, the length d of the closed cavity 60 is the largest, and the image distance between the lens module 40 and the photosensitive device 50 is the largest.

There is a space between the display screen and the back plate of the first portion 10 that can accommodate the enclosed cavity 60 and the light sensing device 50. Specifically, the photosensitive device 50 may be fixed to the inside of the first portion 10 by at least one connection member. The at least one connecting member may be fixed inside the first portion 10 by means of hinge, screw connection, welding, assembling, etc., and the embodiment is not limited to a specific fixing manner.

Similarly, the lens module 40 can be connected by a groove when it is disposed on the outer side 101 of the first portion 10. As shown in the front view and the left view of fig. 4b, a first groove 1011 is formed on the outer side surface 101 of the first portion 10, and the size of the first groove 1011 matches with the size of the lens module 40. Further, referring to a partially enlarged view shown in fig. 4c, the lens module 40 includes a camera 401 and a first connecting member 402, as shown by the structure of the shaded portion, the first connecting member 402 is connected to the first groove 1011, so that the camera 401 is fixed on the first groove 1011 by the first connecting member 402, thereby providing the lens module 40 on the outer side 101 of the first portion 10.

A plurality of such image points form a complete image which is mapped onto the photosensitive device 50. The light sensing device 50 is used for acquiring an image captured by the lens module 40, and feeding the image back to the display screen for display. Further, the photosensitive device 50 may be directly connected to the transparent material closing one end of the cavity 60 to form a closed space. Alternatively, other connecting members may be further included between the photosensitive device 50 and the closed cavity 60 to connect the photosensitive device 50 and the closed cavity 60 and achieve the effect of preventing the incident light from leaking.

Alternatively, the light sensing device 50 may be an image sensor.

In this embodiment, the first portion 10 may be a side where a left screen of the foldable terminal device is located, or a side where a right screen of the terminal device is located. If the first part 10 is the side where the left screen of the foldable terminal device is located, i.e. the camera is located on the left screen, as shown in fig. 5a, for the folded-screen mobile phone folded outward, the right screen is the main screen 201 for displaying the image formed by the photosensitive device 50. If the first part 10 is the side where the right screen of the foldable terminal device is located, i.e. the camera is located on the right screen, as shown in fig. 5b, then for the folded-screen mobile phone folded in, the left screen is the main screen 201 for displaying the image formed by the photosensitive device 50. When the folding screen mobile phone is in an unfolded state and a user faces the screen, the left screen is positioned on one side of the left side of the user; and when the folding screen mobile phone is in an unfolded state and a user faces the screen, the right screen is positioned on one side of the right side of the user.

In the embodiment, the camera is arranged on the outer side surface of the foldable terminal equipment, and the photosensitive device is arranged at a position away from the camera by a closed cavity, so that enough distance exists between the camera and the photosensitive device, and a plurality of groups of lenses can be arranged, thereby realizing continuous adjustment of image distance and field angle in a large range by optical means and improving imaging effect.

In addition, an embodiment of the present application further provides a shooting method, which is applied to the terminal device in the foregoing embodiment, and the terminal device has a shooting function. In addition, the terminal device includes, in addition to the above-described structural components: a processor, a first sensor, and a second sensor. The first sensor is arranged in the first part and used for acquiring a first measurement parameter and reporting the first measurement parameter to the processor, wherein the first measurement parameter comprises the angular velocity and the acceleration of the first part. The second sensor is arranged in the second part and used for acquiring a second measurement parameter and reporting the second measurement parameter to the processor, wherein the second measurement parameter comprises the angular speed and the acceleration of the second part.

The method provided by the embodiment can be executed by the processor or the processing chip.

Specifically, in a configuration of a terminal device, as shown in fig. 2a to 5b, in a case where the lens module 40 is disposed on an outer side 101 of the first portion 10, and the photosensitive device 50 is disposed inside the first portion 10, or disposed on an inner side 102 of the first portion 10, the photographing method includes:

the first step is as follows: and when the folding or unfolding operation is detected, acquiring the first measurement parameter and the second measurement parameter, and determining a first included angle between the first part and the second part according to the first measurement parameter and the second measurement parameter. The first included angle is an included angle between the display screens of the two parts.

Wherein, for the folding screen mobile phone folded outwards, the folding or unfolding operation comprises: unfolding operation: the process of rotating the angle between the two screens of the first and

second sections

10 and 20 from 360 ° to 180 °, or, the folding operation: the angle between the two screens of the first and

second sections

10, 20 rotates from 180 to 360. For a folded screen handset that folds in, the folding or unfolding operation comprises: unfolding operation: the process of rotating the angle between the two screens of the first and

second sections

10 and 20 from 0 ° to 180 °, or, the folding operation: the angle between the two display screens of the first and

second sections

10, 20 is rotated from 180 to 0.

The first angle may be obtained by measuring and calculating by at least one sensor, and specifically, the first sensor disposed in the first portion 10 includes a first gyroscope sensor, a first acceleration sensor, and the like, and the first gyroscope sensor may be configured to measure an angular velocity of the movement of the first portion 10, and the first acceleration sensor may be configured to measure an acceleration of the first portion 10, and report both the measured angular velocity and the measured acceleration of the first portion 10 to the processor. Similarly, a second gyro sensor and a second acceleration sensor in the second portion 20 report the measured angular velocity and acceleration of the second portion 10, respectively, to the processor. The processor calculates the first angle, which may be denoted by "θ", after acquiring the acceleration and angular velocity of the first portion 10 and the second portion 20. In this embodiment, the process of calculating the first included angle θ by the processor according to the acceleration and the angular velocity reported by each part will not be described in detail.

The second step is that: and after the processor acquires the first included angle, judging whether the first included angle reaches a preset angle or not, and staying for a preset time.

The preset time length can be set by itself, for example, the preset time length is not less than 5 seconds. The preset angle is an angle formed by the display screen of the first part and the display screen of the second part in a vertical state. Optionally, the preset angle is 270 ° or 90 °. Further, the preset angle may also be a floating interval of 270 ° or 90 °, for example, if the floating range is above or below 5 °, the preset angle interval is 265 ° to 275 °, or 85 ° to 95 °, inclusive.

It should be understood that the preset angle may also be an included angle between the back plate of the first portion and the back plate of the second portion. For example, when the included angle between the back plates of the two portions is 90 °, an included angle of 270 ° is formed between the display screen of the first portion and the display screen of the second portion, and thus, whether the first included angle reaches the preset angle or not can be determined by determining whether the included angle between the back plates of the two portions reaches the range of 90 °. In this embodiment, the included angle between the display screens of the two portions or the included angle between the back plates of the two portions is used as a judgment basis and is not limited.

The third step: when the first included angle reaches the preset angle or the preset angle interval and stays for the preset time, the lens module 40 on the outer side surface 101 of the first portion 10 is started, and the shot scene is displayed on the display screen of the second portion 20 through the photosensitive device 50.

For example, for a folding mobile phone capable of rotating 0-180 degrees, when the folding mobile phone is in a folded state, the first part 10 is attached to the back plate of the second part 20, and a first included angle θ between the display screens of the two parts is 360 degrees; when the foldable mobile phone is in a process from a folded state to an unfolded state, the first included angle θ may go through 270 ° or any angle between 265 ° and 275 °, and after a certain preset duration, the lens module 40 starts a shooting function to shoot an external scene, and displays a shot picture on the display screen of the second portion 20 through the light sensing device 50, as shown in fig. 6 a.

In addition, optionally, if it is detected that the first included angle θ reaches the preset angle but does not stay for the preset time period, the lens module 40 is not opened.
