The control method is applied to the electronic equipment in the embodiment, the electronic equipment further comprises a camera module and a telescopic display screen, and the camera module can be used for shooting pictures or videos. The flow of the control method of the camera module can comprise the following steps:
in 101, it is identified whether the electronic device is in a shooting state.
With the continuous improvement of the performance of the camera in the electronic device, the user can use the electronic device to shoot images, which is an indispensable part of daily life. The user's demand for the electronic device is not only to be able to capture an image, but also to be able to capture an image with good presentation effect. However, in the related art, it is still inconvenient for the user to operate the electronic device to capture an image. That is, the operability of the electronic device is not high.
It should be noted that, in this embodiment of the application, the electronic device may be configured with a retractable display screen, and the retractable display screen may be a flexible display screen, and the flexible display screen may increase an expanded size of the display screen by stretching, and may also decrease the expanded size of the display screen by shrinking, so as to provide a user with display screens of different sizes.
When the camera application of the electronic equipment is started, the electronic equipment is in a shooting state, the electronic equipment can enter the shooting state through the camera module, the live-action image can be obtained in real time through the camera module, and the live-action image is shot. The electronic device may identify whether the electronic device is currently in a shooting state through the processor, for example, whether the electronic device is currently in the shooting state may be determined through a working state of the camera module, and when the camera module is in the working state, the electronic device is in the shooting state.
At 102, if so, the size of the display expansion area of the retractable display is identified.
And if the electronic equipment is in a shooting state, identifying the size of the expansion area of the telescopic display screen. The retractable display screen may include a fixed display area and an extended display area. The fixed display area is a display area in which the retractable display screen is in a retracted state and is not accommodated in the electronic device. The expanded display area is a display area which can be stored in the electronic device and can be moved to the outside of the electronic device to be increased, and the expanded display area can be contracted into the electronic device or expanded to the outside of the electronic device for displaying.
It can be appreciated that the size of the expansion area of the retractable display screen is adjustable, the minimum size of the expansion area of the retractable display screen is the fixed display area size, the maximum size of the expansion area of the retractable display screen is the fixed display area size plus the total expansion display area size, and the expansion display area can move between the inside of the electronic device and the outside of the electronic device.
In 103, adjusting the distance between the plurality of lenses in the camera module according to the size of the expansion area to change the focal length of the camera module.
In this application embodiment, can be associated the size in telescopic display screen expansion region with the focus of camera module, for example can set up the mapping table between the size in expansion region and the focus of camera module in advance, the size in different expansion regions corresponds the focus of different camera modules.
For example, when the size of the expansion area of the telescopic display screen is the size of the fixed display area, the focal length of the camera module is set to be 1 time of the focal length in advance; when the size of the expansion area of the telescopic display screen is the size of the expansion display area obtained by adding 1 half to the size of the fixed display area, the focal length of the camera module is 2 times that of the fixed display area; when the size of the expansion area of the telescopic display screen is the size of the fixed display area plus the size of the whole expansion display area, the focal length of the camera module is 10 times of the focal length.
The camera module can move lens to assigned position through the motor, realizes the adjustment of focus, and the focus of camera module is big more, and the scenery that can shoot is just farther. After the size that obtains telescopic display screen expansion region, can adjust the distance between a plurality of lenses in the camera module according to the size in expansion region to change the focus of camera module.
For example, the camera module has photoelectric sensor and 5 lenses, and 2 nd lens and 3 rd lens can wholly remove in order to change the focus of camera module as a set of lens. After obtaining the regional size of telescopic display screen expansion, for example when discerning that the size of current expansion region reaches fixed display area and adds 1 half extension display area, according to the mapping table between the size in expansion region and the focus of camera module, the focus of the camera module that corresponds is 2 times focus, then the motor can correspond 2 nd lens of drive and 3 rd lens and move to the assigned position that 2 times focus corresponds to change the focus of camera module and be 2 times focus. Wherein, the 2 nd lens and the 3 rd lens are lenses which are close to the 2 nd and the 3 rd of the photoelectric sensor.
Electronic equipment includes the telescopic display screen in the embodiment of this application, the user is when shooing, can be directly through shrink or stretch the telescopic display screen can correspond the focus of adjustment camera module, whether the user also can directly look over on the telescopic display screen to use the focus after the adjustment to shoot suitable simultaneously, and do not need the user to adjust the camera lens or look for the focus parameter and set up, consequently the user can conveniently adjust the focus of camera module, thereby electronic equipment's operability has been promoted.
It should be noted that, the user can contract or extend the telescopic display screen through manual mode or motor mode, and when the size of user's manual mode adjustment telescopic display screen, the user uses both hands to grip electronic equipment usually, therefore the user not only can be convenient manual adjustment camera module focus, but also can make the shooting more stable, especially when the focus of camera module is great, can be better prevent to shoot the shake.
Referring to fig. 7, fig. 7 is another schematic flow chart of a control method of a camera module according to an embodiment of the present application, where the flow chart may include:
in 201, it is identified whether the electronic device is in a shooting state.
When the camera application of the electronic equipment is started, the electronic equipment is in a shooting state, the electronic equipment can enter the shooting state through the camera module, the live-action image can be obtained in real time through the camera module, and the live-action image is shot. The electronic device may identify whether the electronic device is currently in a shooting state through the processor, for example, whether the electronic device is currently in the shooting state may be determined through a working state of the camera module, and when the camera module is in the working state, the electronic device is in the shooting state.
At 202, if so, the size of the display expansion area of the retractable display is identified.
And if the electronic equipment is in a shooting state, identifying the size of the expansion area of the telescopic display screen. The retractable display screen may include a fixed display area and an extended display area. The fixed display area is a display area in which the retractable display screen is in a retracted state and is not accommodated in the electronic device. The expanded display area is a display area which can be stored in the electronic device and can be moved to the outside of the electronic device to be increased, and the expanded display area can be contracted into the electronic device or expanded to the outside of the electronic device for displaying.
It can be appreciated that the size of the expansion area of the retractable display screen is adjustable, the minimum size of the expansion area of the retractable display screen is the fixed display area size, the maximum size of the expansion area of the retractable display screen is the fixed display area size plus the total expansion display area size, and the expansion display area can move between the inside of the electronic device and the outside of the electronic device.
The retractable display screen can be retracted or extended manually or electrically to adjust the size of the expansion area. When the size of the display screen unfolding area is adjusted manually by a user, the user can apply an external force to one end of the telescopic display screen, and when the external force is applied to one end of the telescopic display screen, the telescopic display screen is driven by the external force to stretch or contract so as to change the size of the telescopic display screen unfolding area. Or, the user can also adjust the size of the display screen expansion area in an electric manner, the electronic device may further include a driving motor, and when the electronic device receives a control instruction of the user, the electronic device controls the driving motor to drive the retractable display screen to extend or retract according to the control instruction, so as to change the size of the retractable display screen expansion area.
It can be understood that, when the user adjusts the size of the retractable display screen in a manual mode, the user usually uses both hands to hold the electronic device, so that the user can conveniently and manually adjust the focal length of the camera module, the shooting can be more stable, and especially when the focal length of the camera module is larger, the shooting shake can be better prevented; and the user has increased the mutual interaction between user and the electronic equipment through the module focus of manual adjustment camera, has promoted electronic equipment's maneuverability.
In one embodiment, the retractable display screen rotates around a rotating shaft; identifying the size of the expansion area of the telescopic display screen comprises acquiring the rotation angle of a rotating shaft; and calculating the size of the expansion area of the telescopic display screen according to the rotation angle. It can be understood that the retractable display screen rotates around the rotating shaft, and the structure of the rotating shaft can refer to the structure of the driving member in the above implementation, and the structure of the rotating shaft is not described herein again.
No matter the telescopic display screen removes the electronic equipment outside from the electronic equipment inside, still removes the electronic equipment outside from the electronic equipment inside, the telescopic display screen rotation can all be followed to the pivot, can set up an angle sensor in pivot department, through the turned angle of angle sensor monitoring pivot. For example, when the expanded display area moves from the inside of the electronic device to the outside of the electronic device, the rotation angle of the rotation shaft increases as the rotation shaft rotates. When the expanded display area moves from the outside of the electronic equipment to the inside of the electronic equipment, the rotating shaft rotates along with the expanded display area, and the rotating angle of the rotating shaft is smaller. For example, the rotation angle is 720 degrees, which means that the rotation shaft rotates twice. It should be noted that, when the expandable display area of the retractable display screen is located inside the electronic device, the rotation angle of the rotating shaft is set to zero.
And calculating the size of the expansion area of the telescopic display screen according to the rotation angle. After the rotation angle of the rotating shaft is obtained, the size of the expansion area of the telescopic display screen can be calculated according to the rotation angle of the rotating shaft. For example, the size of the display screen expansion area can be calculated through the rotation angle of the rotating shaft and the radius of the rotating shaft.
It should be noted that the size of the display screen expansion area can also be calculated by other methods. For example, a distance sensor may be provided at the edge of the fixed display area, which may measure the size of the current deployment area. The size of how to identify the display screen expansion area is not limited.
In 203, it is identified whether the size of the deployment area reaches a preset size.
In the embodiment of the application, after the size of the expansion area of the telescopic display screen is obtained, whether the size of the expansion area reaches the preset size is judged. The preset size can be set according to the requirement, and the preset size can be one or more.
For example, the preset size may be set to a size of the fixed display area; for another example, the preset size may be the size of the extended display area obtained by adding 1 half to the size of the fixed display area; for another example, the preset size may be the size of the fixed display area plus the size of the entire extended display area.
At 204, if the size of the expansion area does not reach the preset size, the distance between the plurality of lenses in the camera module is maintained, so that the focal length of the camera module is the first focal length.
In the embodiment of the application, the mapping table between the focal lengths of the preset sizes and the camera modules can be preset, and different preset sizes correspond to different focal lengths of the camera modules.
For example, when the preset size is the size of the fixed display area, the focal length of the camera module is set to be 1 time of the focal length; when the preset size is the size of the extended display area which is obtained by adding 1 half to the size of the fixed display area, the focal length of the camera module is 2 times of the focal length; when the preset size is the fixed display area size plus the whole expanded display area size, the focal length of the camera module is 10 times of the focal length.
The camera module can move lens to assigned position through the motor, realizes the adjustment of focus, and the focus of camera module is big more, and the scenery that can shoot is just farther. After obtaining the regional size of telescopic display screen expansion, discernment expansion region is for predetermineeing the size, if do not reach the default size, then do not adjust the focus of current camera module, also keep the distance between a plurality of lenses in the camera module to the focus that makes the camera module keeps being current first focus.
For example, when the telescopic display screen is in the shrink state, the size of the expansion region of telescopic display screen is fixed display area, and the display area of extension is all accomodate inside electronic equipment, and the focus of the camera module that corresponds this moment is first focus, and wherein, first focus can be the default focus of camera module, for example can be 1 times focus.
In the shooting process of a user, the telescopic display screen of the electronic equipment is stretched, and whether the size of the expansion area reaches the preset size or not is identified. For example, the preset size may be the size of the extended display area obtained by adding 1 half to the size of the fixed display area, and when it is recognized that the size of the extended display area outside the electronic device does not reach half, it is considered that the size of the extended display area does not reach the preset size, and at this time, the distance between the plurality of lenses in the camera module is maintained, so that the focal length of the camera module is maintained as the current first focal length.
In 205, if the size of the expansion area reaches the predetermined size, the distance between the plurality of lenses in the camera module is adjusted, so that the focal length of the camera module is the second focal length, and the second focal length is not equal to the first focal length.
For example, the size of the expansion area of the telescopic display screen is a fixed display area, and the focal length of the corresponding camera module is the first focal length.
In the shooting process of a user, the telescopic display screen of the electronic equipment is stretched, and whether the size of the expansion area reaches the preset size or not is identified. For example, the preset size may be the size of the extended display area obtained by adding 1 half to the size of the fixed display area, and when the size of the extended display area outside the electronic device is identified to reach half, the size of the extended area is considered to reach the preset size, and the distances between the plurality of lenses in the camera module are adjusted according to a mapping table between the preset size and the focal length of the camera module, so that the focal length of the camera module is changed from the first focal length to the second focal length. For example, the second focal length may be 2 times the first focal length. When the telescopic display screen continues to be stretched, and the extended display area is recognized to be in the stretching state, the distance between the plurality of lenses in the camera module is adjusted according to the mapping table so that the focal length of the camera module is changed from the second focal length to the third focal length. For example, the third focal length may be 10 times the first focal length.
For another example, when the size of the expansion area of the retractable display screen is the fixed display area plus the entire expansion display area, the focal length of the corresponding camera module is the first focal length.
During shooting, a user retracts the retractable display screen of the electronic device and identifies whether the size of the expansion area reaches a preset size. For example, the preset size may be the size of the extended display area obtained by adding 1 half to the size of the fixed display area, and when the size of the extended display area outside the electronic device shrinks to half, the size of the extended area is considered to reach the preset size, and then the distance between the plurality of lenses in the camera module is adjusted according to a mapping table between the preset size and the focal length of the camera module, so that the focal length of the camera module is changed to the second focal length. For example, the second focal length may be 1/2 the first focal length. When the telescopic display screen continues to be contracted, and the expanded display area is identified to be in a contracted state, the distance between the plurality of lenses in the camera module is adjusted according to the mapping table so that the focal length of the camera module is changed from the second focal length to the third focal length. For example, the third focal length may be 1/10 times the first focal length.
The predetermined size may be one or more. When the preset size is multiple, the judgment can be carried out in sequence to obtain the corresponding focal length.
For example, the preset sizes may include a first preset size, a second preset size, and a third preset size. The first preset size can be the size of a fixed display area, and the focal length of the corresponding camera module is a first focal length; the second preset size can be the size of the extended display area obtained by adding 1 half to the size of the fixed display area, and the focal length of the corresponding camera module is the second focal length; the third preset size can be the size of the fixed display area plus the size of the whole extended display area, and the focal length of the corresponding camera module is the third focal length.
The size of the current expansion area is a first preset size, the focal length of the corresponding camera module is a first focal length, a telescopic display screen is stretched in the shooting process of a user, whether the size of the expansion area reaches a third preset size or not can be judged firstly, and if the size reaches the third preset size, the distance between a plurality of lenses in the camera module is adjusted, so that the focal length of the camera module is a third focal length; if the size of the expansion area does not reach the third preset size, judging whether the size of the expansion area reaches the second preset size, and if the size of the expansion area reaches the second preset size, adjusting the distance between a plurality of lenses in the camera module to enable the focal length of the camera module to be the second focal length; if the size of the expansion area does not reach the second preset size, the distance between the plurality of lenses in the camera module is kept, so that the focal length of the camera module is kept as the first focal length. The second focal length is 2 times of the first focal length, and the third focal length is 10 times of the first focal length. The first focal length may be a default focal length of the camera module, such as 1-fold focal length.
It should be noted that the numerical values in the above embodiments are only examples, and in other embodiments, the number and the size of the preset sizes may be adjusted as needed, or corresponding focal length data may be set as needed, and the relationship between the multiple of the back focal length and the first focal length is adjusted.
In one embodiment, if the size of the expansion area reaches a preset size, adjusting the distance between the plurality of lenses in the camera module to make the focal length of the camera module be the second focal length includes: determining a preset lens from a plurality of lenses; obtaining the moving distance of the preset lens according to the corresponding relation between the preset size of the preset expansion area and the position of the preset lens; the preset lens is driven to move the moving distance relative to other lenses so as to change the focal length of the camera module.
The camera module comprises a plurality of lenses, and the camera module can adjust the focal length by changing the positions of one or more preset lenses.

Then the preset lens is driven to move the moving distance relative to other lenses so as to change the focal length of the camera module.
For example, the camera module has photoelectric sensor and 5 lenses, 2 nd and 3 rd lens can move as predetermineeing the lens wholly, obtain telescopic display screen expansion area's size after, obtain according to the mapping table and predetermine the position that the lens will be located, thereby calculate 2 nd and 3 rd lens and need the distance that removes at present, then correspond 2 nd and 3 rd lens of drive and remove, change the distance of 2 nd and 3 rd lens and other lenses, thereby change the focus of camera module. Wherein, the 2 nd lens and the 3 rd lens are lenses which are close to the 2 nd lens and the 3 rd lens of the photoelectric sensor. If necessary, only the 2 nd lens or the 3 rd lens may be adjusted, or other lenses such as the 1 st lens, the 4 th lens or the 5 th lens may be adjusted.
In an embodiment, the camera module may also include other numbers of lenses, such as 7 lenses, 9 lenses, etc., and the preset lenses may also be multiple, such as 3 preset lenses, 4 preset lenses, etc. The embodiment of the application can preset the corresponding relation between the preset size of the expansion area and the positions of a plurality of preset lenses. When the preset lens is a plurality of, and when the size of the expansion area reaches the preset size, the preset lens is driven to move relative to other lenses by the movement distance including: obtaining the moving distance and the moving direction corresponding to the preset lenses respectively according to the corresponding relation between the preset size of the preset expansion area and the positions of the preset lenses; and driving the plurality of preset lenses to move towards the corresponding moving directions respectively by the moving distance so as to enable the focal length of the camera module to be the second focal length. It can be understood that, when the preset lenses are multiple, based on the current positions of the multiple preset lenses, the corresponding directions and distances to be moved of the different preset lenses can be obtained according to the corresponding relationship between the preset size of the expansion area and the positions of the multiple preset lenses, and the moving directions and distances of the different preset lenses can be different from each other or can be different from each other as required.
In an embodiment, the photosensor and the lens, such as the 1 st lens and the photosensor, can be adjusted according to needs, and the function of adjusting the focal length of the camera module can also be realized.
It can be understood that the moving distance of the lens is very small, the moving distance of the telescopic display screen is far greater than that of the lens, the moving distance of the telescopic display screen is converted into the moving distance of the lens according to a preset proportion, the moving distance of the lens is adjusted by adjusting the size of the expansion area, the adjusting precision is high, the moving distance of the lens is adjusted more accurately, and a user can easily adjust the focal length to be wanted. In one embodiment, driving the preset lens to move the moving distance relative to the other lens when the size of the expansion area reaches a preset size comprises: identifying a trend of change in the size of the deployment area; if the variation trend is larger, adjusting the distance between a plurality of lenses in the camera module to increase the focal length of the camera module; if the variation trend is smaller, adjusting the distance between a plurality of lenses in the camera module to reduce the focal length of the camera module. And acquiring the variation trend of the size of the expansion area, namely acquiring whether the telescopic display screen is stretched or contracted, wherein if the variation trend is larger, the telescopic display screen is stretched, and if the variation trend is smaller, the telescopic display screen is contracted.
The camera module comprises a plurality of lenses, and the camera module can further realize the adjustment of the focal length by changing the positions of one or more preset lenses. When the telescopic display screen is stretched, can adjust distance between a plurality of lenses in the camera module to increase the focus of camera module. When the telescopic display screen is contracted, the distance between a plurality of lenses in the camera module can be adjusted, and the focal length of the camera module is reduced.
For example, the size of the current expansion region is the fixed display region size, and the corresponding camera module focus is first focus, and when the user in shooting process, the telescopic display screen is stretched for the size of the current expansion region reaches the fixed display region size and adds 1 half the size of the expansion display region, and the trend of change of the size of the expansion region is the grow, and the focus of the corresponding camera module is the second focus. For example, the second focal length is 2 times the first focal length.
For example, the camera module has photoelectric sensor and 5 lenses, and the 2 nd lens and the 3 rd lens can wholly move as the preset lens to change the focal length of the camera module. According to the preset size of the preset expansion area and the corresponding relation between the positions of the preset lenses, when the size of the expansion area reaches the expansion display area with the size of the fixed display area plus 1 half, the positions of the 2 nd lens and the 3 rd lens to be located are obtained, the moving distance of the 2 nd lens and the 3 rd lens which need to move at present is calculated, then the motor drives the 2 nd lens and the 3 rd lens to move the moving distance, and the focal distance of the camera module is changed into the second focal distance.
For another example, the size of the current expansion area is larger than the size of the expansion display area obtained by adding 1 half to the size of the fixed display area, but the expansion display area is not fully extended, the focal length of the corresponding camera module is the first focal length, when the user takes a picture, the telescopic display screen is contracted, so that the size of the current expansion area is the size of the fixed display area, the variation trend of the size of the expansion area is reduced, and the focal length of the corresponding camera module is the second focal length. For example, the second focal length is 1/2 the first focal length.
Similarly, for example, the camera module has 5 lenses, and the 2 nd lens and the 3 rd lens can move as a whole to change the focus of camera module as presetting the lens. According to the preset size of the preset expansion area and the corresponding relation between the positions of the preset lenses, the positions where the 2 nd lens and the 3 rd lens are to be located when the size of the expansion area is the size of the fixed display area are obtained, so that the moving distance of the 2 nd lens and the 3 rd lens which need to move at present is calculated, then the 2 nd lens and the 3 rd lens are driven by the motor to move the moving distance, and the focal distance of the camera module is changed into the second focal distance. The 2 nd lens and the 3 rd lens can be a lens close to the 2 nd lens and a lens close to the 3 rd lens of the photoelectric sensor.
It is understood that, after identifying whether the size of the deployment region reaches the preset size, the method may further include: if the size of the expansion area does not reach the preset size, prompting a user to adjust the size of the expansion area so as to adjust the focal length of the camera module to be the second focal length.
If the size of the expansion area changes but does not reach the preset size, the focal length of the camera module cannot be adjusted at the moment, the electronic equipment can pop up a prompt box to prompt a user to adjust the size of the expansion area, for example, the expanded display area continues to be expanded, so that the size of the expansion area reaches the preset size, when the size of the expansion area reaches the preset size, the distance between a plurality of lenses in the camera module is adjusted, and the focal length of the camera module is adjusted to be the second focal length from the current first focal length.

Referring to fig. 8 to 9, fig. 8 is a schematic view of a scenario of an apparatus control method according to an embodiment of the present application, and fig. 9 is a schematic view of another scenario of the apparatus control method according to the embodiment of the present application. The electronic equipment provided by the embodiment comprises the telescopic display screen. The retractable display screen may be a display screen that is retractable. The retractable display screen may be a flexible display screen that may be extended and retracted, etc. On the electronic equipment provided with the telescopic display screen, the expansion size of the display screen can be increased by stretching the display screen, and the expansion size of the display screen can be reduced by contracting the display screen. As shown in fig. 8, fig. 8 shows the configuration of the display screen of the electronic device when the retractable display screen is in the retracted state, and the configuration of the display screen of the electronic device when the retractable display screen is in the extended state.
When the camera application of the electronic equipment is started, the electronic equipment is in a shooting state, the electronic equipment can enter the shooting state through the camera module, the live-action image can be obtained in real time through the camera module, and the live-action image is shot.
And if the electronic equipment is in a shooting state, identifying the size of the expansion area of the telescopic display screen. The retractable display screen may include a fixed display area and an extended display area. The fixed display area is a display area in which the retractable display screen is in a retracted state and is not accommodated in the electronic device. The extended display area is a display area that can be accommodated inside the electronic device and can be moved to the outside of the electronic device to be increased.
It will be appreciated that the size of the display area of the retractable display screen is adjustable, the size of the display area of the retractable display screen is at least the fixed display area size, the size of the display area of the retractable display screen is at most the fixed display area size plus the total extended display area size, and the extended display area is movable between the interior of the electronic device and the exterior of the electronic device.
And after the size of the expansion area of the telescopic display screen is obtained, judging whether the size of the expansion area reaches the preset size. The preset size can be set as required, and it can be understood that the preset size may be one or more.
In the embodiment of the application, the mapping table between the focal lengths of the preset sizes and the camera modules can be preset, and different preset sizes correspond to different focal lengths of the camera modules. For example, when the preset size is the size of the fixed display area, the focal length of the camera module is set to be 1 time of the focal length; when the preset size is the size of the extended display area which is obtained by adding 1 half to the size of the fixed display area, the focal length of the camera module is 2 times of the focal length; when the preset size is the fixed display area size plus the whole expanded display area size, the focal length of the camera module is 10 times of the focal length.
The camera module can move the lens to the designated position through the motor so as to adjust the focal length. After obtaining the regional size of telescopic display screen expansion, discernment expansion region is for predetermineeing the size, if do not reach the default size, then do not adjust the focus of current camera module, also keep the distance between a plurality of lenses in the camera module to the focus that makes the camera module keeps being current first focus.
If the size of the expansion area reaches the preset size, the distance between the plurality of lenses in the camera module is adjusted, so that the focal length of the camera module is the second focal length, and the second focal length is not equal to the first focal length.
For example, when the telescopic display screen is in the shrink state, the size of the expansion area of telescopic display screen is fixed display area, and the expanded display area is all accomodate inside electronic equipment, and first focus this moment can be the default focus of camera module, for example can be 1 times focus.
During shooting, a user stretches a retractable display screen of the electronic device, and then identifies whether the size of the expansion area is equal to a preset size, for example, the preset size may be the size of the expansion display area obtained by adding 1 half to the size of the fixed display area.
If the size of the expanded display area outside the electronic equipment does not reach half, the size of the expansion area is considered to not reach the preset size, and the distance between the plurality of lenses in the camera module is kept at the moment so that the focal length of the camera module is kept to be the current first focal length.
If the size of the expanded display area outside the electronic equipment reaches half, the size of the expanded display area is considered to reach the preset size, and the distances between the plurality of lenses in the camera module are adjusted according to a mapping table between the preset size and the focal length of the camera module, so that the focal length of the camera module is changed into the second focal length. For example, the second focal length may be 2 times the focal length.
If the retractable display screen of the electronic device continues to be stretched and the retractable display screen is in a fully extended state, the size of the expansion area of the retractable display screen is the size of the fixed display area plus the size of the full expansion display area, and at this time, the corresponding focal length of the camera may be the third focal length. For example, the third focal length may be 10 times the focal length.
Specifically, the camera module includes a plurality of lenses, and the camera module can adjust the focal length by changing the position of one or more preset lenses. The embodiment of the application can preset the preset size of the expansion area, the focal length of the camera module and the corresponding relation between the positions of the preset lenses, such as setting a mapping table and the like.
When the size of the expansion area reaches the preset size, the moving distance of the current preset lens to be moved can be calculated according to the preset size of the expansion area and the corresponding relation between the positions of the preset lens, and then the preset lens is driven to move the moving distance relative to other lenses so as to change the focal length of the camera module.
The electronic device can identify a trend of change in the size of the expansion area; if the variation trend is larger, adjusting the distance between a plurality of lenses in the camera module to increase the focal length of the camera module; if the variation trend is for diminishing, then adjust the distance between a plurality of lenses in the camera module to reduce the focus of camera module.
Referring to fig. 9, for example, the camera module has a prism 220, a photo sensor 280 and 5 lenses (the other 3 lenses are not shown). The 2 nd lens 240 and the 3 rd lens 260 can integrally move as a preset lens to change the focal length of the camera module. When the size of the currently expanded area of the display screen 290 of the electronic device is the fixed display area size, the corresponding focal length of the camera module is the first focal length, for example, 1-fold focal length. In the shooting process, a telescopic display screen is stretched, so that when the size of the current expansion area of the display screen 290 of the electronic device reaches the expansion display area with the size of the fixed display area plus 1 half, the positions where the 2 nd lens 240 and the 3 rd lens 260 are to be located are obtained according to the preset size of the expansion area and the corresponding relation between the positions of the preset lenses, the moving distance that the 2 nd lens 240 and the 3 rd lens 260 need to move at present is calculated, then the 2 nd lens 240 and the 3 rd lens 260 are driven by a motor to move the moving distance, and the focal length of the camera module is changed from the first focal length to the second focal length. For example, the second focal length may be 2 times the first focal length. When the telescopic display screen continues to be stretched and the currently expanded display area of the display screen 290 of the electronic device is recognized to be in the stretching state, the positions where the 2 nd lens 240 and the 3 rd lens 260 are to be located are obtained according to the corresponding relation between the preset size of the preset stretching area and the preset lens position, so that the moving distance that the 2 nd lens 240 and the 3 rd lens 260 need to move at present is calculated, then the motor drives the 2 nd lens 240 and the 3 rd lens 260 to move continuously for the moving distance, and therefore the focal length of the camera module is changed from the second focal length to the third focal length. For example, the third focal length may be 10 times the first focal length.
