Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
As shown in Figure 1, it is shown that a kind of smart phone manual focus method according to the present invention, comprising the following steps:
Step 1: obtaining user gesture, the moving range of lens driving motor is determined according to user gesture.
In this step, module is obtained by gesture and obtains the gesture of user apart from acquisition module.Then according to default
Rule by the gesture operation of user be converted to adjustment lens driving motor moving range instruction.Wherein, according to preset rule
The gesture operation of user is then converted to the instruction of adjustment lens driving motor moving range, comprising: detecting user gesture A
When, lens driving motor is mobile in remote burnt section；When detecting user gesture B, lens driving motor is mobile in middle burnt section；
When detecting user gesture C, lens driving motor is mobile in nearly burnt section.
It is to be appreciated that should also include: user using rear camera, and select manual focus before this step
Mode.After rear camera preview shooting picture, lens driving motor remains unchanged the quasi- focal position of rear camera,
Until user's operation gesture trigger manual focus, then lens driving motor is with the progress of the distance between user gesture and screen
It is mobile.
Step 2: acquiring the distance between user gesture and screen information in real time, and driven by mobile gesture control camera lens
Dynamic motor moves in moving range, to realize the focusing of camera lens.
In the step, module is obtained by distance and acquires the distance between user gesture and screen information.It is specific one
In embodiment, it can be range sensor that distance, which obtains module,.
In the embodiment shown in Figure 2, when detecting user gesture A, lens driving motor works in remote burnt section.It is first
First, lens driving motor is moved to the default location of remote coke, changes then as the distance between user gesture and screen and moves
Dynamic, when gesture A is to close to screen direction movement, distance obtains module and gets what the distance between gesture A and screen became smaller
Information, lens driving motor are pulled to remote coke, to complete to focus.When gesture A is to far from screen direction movement, distance obtains mould
Block gets the information that the distance between gesture A and screen become larger, and lens driving motor is pulled to nearly coke, to complete pair of camera lens
It is burnt.
When detecting user gesture B, lens driving motor works in middle burnt section.Firstly, lens driving motor is mobile
To the default location of middle coke, change then as the distance between user gesture and screen and move, when gesture B is to close to screen
When direction is mobile, distance obtains module and gets the information that the distance between gesture B and screen become smaller, and lens driving motor is pushed away
To remote coke, to complete to focus.When gesture B to it is mobile far from screen direction when, distance obtain module get gesture B and screen it
Between the information that becomes larger of distance, lens driving motor is pulled to nearly coke, to complete the focusing of camera lens.
When detecting user gesture C, lens driving motor works in nearly burnt section.Firstly, lens driving motor is mobile
To the default location of nearly coke, change then as the distance between user gesture and screen and move, when gesture C is to close to screen
When direction is mobile, distance obtains module and gets the information that the distance between gesture C and screen become smaller, and lens driving motor is pushed away
To remote coke, to complete to focus.When gesture C to it is mobile far from screen direction when, distance obtain module get gesture C and screen it
Between the information that becomes larger of distance, lens driving motor is pulled to nearly coke, to complete the focusing of camera lens.
Second aspect, this application provides at a kind of smart phone manual focus system, including gesture acquisition module, information
Manage module, distance obtains module and control module.Gesture obtains the gesture that module is used to obtain user；Message processing module is used for
Acquired gesture operation is converted to the instruction of adjustment lens driving motor moving range according to default rule；Distance obtains
Module is for acquiring the distance between user gesture and screen information；Control module is used to be controlled according to range information collected
Lens driving motor moves in moving range, to realize the focusing of camera lens.
Compared with the prior art, the advantages of the present invention are as follows:
The application, which passes through, obtains user gesture, and the moving range of lens driving motor is determined according to user gesture, then
Acquisition the distance between user gesture and screen information in real time, and by mobile gesture control lens driving motor in moving range
Interior mobile focusing.The mobile method of the control lens driving motor of this kind of segmented is able to use the more arbitrary control in family
