The relation formula of the lens visual angle and the telescopic quantity is as follows:
d＝r-l(cotθ+secθ)
Wherein d is the telescopic amount of the lens module, theta is the lens visual angle, and r and l are constant term coefficients.
In another embodiment proposed by the present disclosure, as shown in fig. 6, the electronic device further includes a screen 60, a viewing angle adjusting tool 61 is displayed on the screen 60, and the control chip 40 further includes:

In the present embodiment, when the user starts the image capturing function of the electronic apparatus, the viewing angle adjusting unit 430 of the control chip 40 controls the screen 60 to display the viewing angle adjusting tool 61 in response to the start of the image capturing function. Then, the user can select a required lens angle through the angle-of-view adjustment tool 61, and after the user has selected the lens angle, the control chip 40 controls and drives the panoramic lens module 20 to extend and retract through the extension amount determination unit 410 and the extension control unit 420, so that the lens angle of the panoramic lens 21 reaches the lens angle selected by the user.
The viewing angle adjusting tool 61 may include a slide bar or a digital input box, and in one embodiment, the viewing angle adjusting tool includes a digital input box. A user inputs a required lens angle to the input box in a digital form (for example, 110 °) through the digital input box, and then, after receiving the lens angle input by the user, the control chip 40 performs subsequent data processing to control and drive the panoramic lens module 20 to extend and retract, so that the lens angle of the panoramic lens 21 reaches the lens angle (110 °) selected by the user.

A lens angle of view determining unit 440, configured to calculate the selected lens angle of view according to a sliding distance and a sliding direction of the sliding operation on the slider, and an angle of increase or decrease of the lens angle of view by a unit length of sliding on the slider.
the screen of the electronic equipment is directly displayed in a sliding mode through the sliding strip, for example, the screen can be displayed on a viewing interface in the shooting process, so that redundant keys do not need to be arranged in the electronic equipment, the structure of the electronic equipment is simplified, the fatigue of fingers caused by the fact that a user operates physical keys for many times is avoided, and the user can operate the electronic equipment more conveniently and more comfortably.
For example, in one embodiment, if the unit length of the sliding on the sliding bar is such that the increase and decrease angle of the lens angle is 10 degrees per centimeter, after the user slides 1.5 centimeters in the positive direction of the sliding bar 611, the lens angle selected by the user is increased by 15 degrees based on the existing lens angle of the panoramic lens 21. When the user slides 1.1 cm in the negative direction of the slide bar, the view angle selected by the user is reduced by 11 degrees based on the existing view angle of the panoramic lens 21. The negative direction is a reverse direction of the positive direction, and the positive direction may be from left to right, or from top to bottom, or from bottom to top, which is not limited herein.
Referring to fig. 8, in another embodiment of the present disclosure, the sliding bar includes a plurality of sliding bars, and the unit length of the sliding bar makes the angle of increasing or decreasing the angle of the lens viewing angle different, and the control chip 40 further includes:

In the using process, a user can select one of the sliding bars to activate, and then slide on the selected sliding bar to select the lens view angle.
in one embodiment, the manner of activating the sliding bars may be that, after the user starts the image capturing function of the electronic device, the viewing angle adjusting unit 430 of the control chip 40 responds to the start of the image capturing function, the control screen 60 displays a plurality of sliding bars and displays an angle at which the sliding unit length increases or decreases the lens viewing angle, after the user selects one of the sliding bars, the other sliding bars disappear, and only the sliding bar selected by the user is left to be displayed on the screen, so that the user can slide on the sliding bar selected by the user to select the lens viewing angle.
In another embodiment, after the user starts the image capturing function of the electronic device, the view angle adjusting unit 430 of the control chip 40 may control the screen 60 to display a plurality of sliders and display an angle at which the unit length of the slider increases or decreases the lens view angle in response to the start of the image capturing function, and after the user selects one of the sliders, the user directly slides on the selected slider to select the lens view angle, and simultaneously other sliders that are not selected are still displayed on the screen to wait for the activation of the user. In this way, when the user can firstly slide the unit length to make the slide bar with the larger increase/decrease angle of the lens angle roughly adjust the lens angle of the panoramic lens 21 to the lens angle that the user wants to select, and then slide the unit length to make the slide bar with the smaller increase/decrease angle of the lens angle accurately adjust to the lens angle that the user wants to select.
make like this through slip unit length the different slide bars of angle of increase and decrease of camera lens visual angle can be in quick adjustment in the camera lens visual angle, realize accurate the regulation, convenience of customers carries out the switching of camera lens visual angle fast accurately, is favorable to the user to take a candid photograph the operation that needs quick completion such as wait.
In some shooting scenes, the requirement of a user on the angle of view of a lens is not accurate, but the requirement is met for a scene needing to be shot clearly, but due to the limitation of the adjustable angle of the depth of field of the panoramic lens, the distance between the panoramic lens and the shot scene needs to be controlled, so that the scene needing to be shot clearly by the user is all located within the range of the depth of field of the panoramic lens. Generally, in an adjustment manner in the prior art, the distance between the panoramic lens and the photographed scene is controlled by moving the whole electronic device, but when a user has a relatively precise requirement on the distance between the panoramic lens and the photographed scene, the manner of moving the electronic device obviously causes a relatively large error, and at this time, the above-mentioned purpose can be achieved by driving the panoramic lens to extend and retract.
Therefore, referring to fig. 9, in another embodiment of the present disclosure, the sliding bar includes at least one view angle adjusting sliding bar and one distance adjusting sliding bar, and the control chip 40 further includes:

Therefore, in this embodiment, the user can directly select the amount of expansion of the panoramic lens to control the expansion of the panoramic lens 21, so that the panoramic lens 21 expands to the required lens angle.
