Referring to fig. 1, a flow chart of performing focusing on a computer-readable storage medium for focusing according to an embodiment of the present invention is shown. Wherein the computer readable storage medium has stored thereon a computer program. The computer program realizes the following steps when the processor executes focusing:
s001: acquiring a preview image through a lens of the computer-readable storage medium;
firstly, a shooting module in a computer readable storage medium is started, the shooting module opens a built-in image acquisition sensor according to a starting instruction, and the image acquisition sensor acquires a preview image through a lens arranged in the shooting module. The preview image acquired by the lens can be displayed on a screen of the computer storage medium through a display module in the computer readable storage medium.
S002: selecting at least one target to be focused in the preview image;
after the lens of the computer-readable storage medium acquires a preview image, the computer-readable storage medium can further sequentially select the targets to be focused in the image. The target to be focused is a focusing object which a user needs to be capable of clearly imaging. The target to be focused may be a person, an animal, a still object, or some point in an image. In this embodiment, the number of targets to be focused is not limited.
S003: judging the farthest target to be focused which is farthest away from the lens in the targets to be focused;
in order to execute the focusing instruction for the targets to be focused, the computer-readable storage medium firstly needs to judge the relative positions of all the targets to be focused, judge the target to be focused which is farthest away from the computer-readable storage medium in the plurality of targets to be focused, and take the farthest target to be focused as a reference object for executing the focusing instruction, so as to ensure that all the selected targets to be focused in the preview image can be clearly imaged in the same image.
S004: controlling the lens to deflect towards the farthest target to be focused so as to obtain the maximum deflection angle of the lens;
according to the judgment result obtained in step S003, the computer readable storage medium automatically deflects the lens of the photographing module toward the farthest object to be focused, and changes the position of the object plane to be focused, so as to ensure that the farthest object to be focused is within the depth of field, thereby obtaining a clear image. After the deflection is completed, the deflection angle is recorded and set to the maximum deflection angle.
S005: merging the targets to be focused into a merged focusing target;
preferably, the merged focusing target is a focusing area including each of the targets to be focused.
The computer-readable storage medium establishes a plane coordinate system of XY axes in the preview image displayed in the image preview interface, obtains the coordinate positions of the multiple targets to be focused selected in step S002 in the plane coordinate system, and defines a focusing area containing all the targets to be focused in the preview image according to each coordinate position, that is, the combined focusing target.
S006: receiving a focusing instruction for the combined focusing target;
after the selection of the target to be focused is completed, the user may further send a focusing instruction to the computer-readable storage medium through a preset gesture or operation to control the computer-readable storage medium to perform focusing on the combined focusing target combined by the targets to be focused in the acquired preview image. Wherein the preset gesture or operation may include: the user can set or modify the focus button by clicking the focus button, swiping the operation interface, pressing for a long time and the like according to personal habits of the user.
S007: executing the focusing instruction on the combined focusing target based on the maximum deflection angle.
And according to the focusing instruction, the computer readable storage medium controls the lens in the shooting module to focus the combined focusing target as a whole. The lens deflects based on the maximum deflection angle obtained in S005, the optical axis deflects along with the deflection of the lens, and at the same time, the position of the object plane also deflects, thereby enlarging the depth of field, so that a plurality of targets to be focused, which are not originally on the same object plane, can be on the same object plane, thereby obtaining a clear image.
Referring to fig. 2, a flowchart illustrating a process of performing focusing on a computer-readable storage medium for focusing according to an embodiment of the present invention is shown. In this embodiment, the step of determining the farthest target to be focused, which is farthest from the lens, of the targets to be focused further includes:
s301: sequentially focusing each target to be focused, and simultaneously recording the moving steps of the lens on each target to be focused when focusing;
after the computer readable storage medium selects a plurality of targets to be focused in a preview image, the computer readable storage medium sequentially focuses on each target to be focused by changing the relative position of the lens so as to ensure that the target to be focused is imaged clearly. Generally, the focusing adopted in the present embodiment will continuously generate a new preview image during the focusing process. When focusing is started, the computer readable storage medium sends the frame of preview image acquired when the lens is at the initial position to an image processor (ISP) for processing to obtain the statistical information of the preview image, and then sends the statistical information to a focusing algorithm library (which can be executed on ISP hardware or driver software), and the focusing algorithm library calculates the distance to which the lens moves in the next step according to the hardware specification and the statistical information and drives the lens to reach the position; and then obtaining a new preview image at the position, further calculating statistical information of the new preview image, further calculating the lens position of the next step, and repeating the steps until the definition of the target to be focused in the preview image gradually changes to a certain degree, thereby completing focusing.
S302: and judging the distance between the target to be focused and the lens corresponding to the moving step number according to the moving step number.
Aiming at different targets to be focused in the same preview image, the distance between the actual position of the targets to be focused and the lens is different, so that the moving steps of the lens for each target to be focused are different in the focusing process. Therefore, the relative position of the target to be focused can be judged according to the moving steps of the lens in the focusing process. In this embodiment, the target to be focused with the least number of moving steps is the farthest target to be focused.
Referring to fig. 3, a flowchart illustrating a process of performing focusing on a computer-readable storage medium for focusing according to an embodiment of the present invention is shown. In this embodiment, the step of controlling the lens to deflect towards the farthest target to be focused to obtain the maximum deflection angle of the lens further includes:
s401: controlling the lens to deflect towards the farthest target to be focused through a tilting actuator;
the computer readable storage medium controls the lens deflection in the shooting module to change the focused object plane through the built-in tilting actuator so as to ensure that clear imaging of a target to be focused can be obtained.
S402: adjusting the deflection angle of the lens to control the farthest target to be focused to be within the depth of field range of the lens;
and adjusting the deflection angle of a lens in the shooting module, so that the farthest target to be focused which is originally positioned in the front and back of the object plane and exceeds the depth of field range is positioned in the depth of field range. The depth of field range is a range of distances between the front and rear of the subject measured at the front edge of the camera lens or other imager, where a sharp image can be obtained.
S403: setting the adjusted deflection angle as a maximum deflection angle.
When the tilt actuator controls the lens to deflect to a deflection angle, the farthest target to be focused can be controlled to be within the depth of field range of the lens, a clear image is obtained, the deflection angle is recorded, the deflection angle is set as a maximum deflection angle, and when a subsequent computer readable storage medium focuses on a combined focusing target comprising a plurality of targets to be focused, the lens is controlled to deflect within the deflection angle range, so that all the targets to be focused are all within the depth of field range, and therefore focusing and clear imaging of the plurality of targets to be focused in the same preview image are achieved.
In a preferred embodiment, the step of executing the focusing instruction on the merged focusing target based on the maximum deflection angle further includes:
and calling a focusing algorithm to execute the focusing instruction on the combined focusing target.
The focusing principle is basically the same as the focusing principle provided in step S301, when a focusing instruction is executed on a combined focusing target, the combined focusing target is regarded as a focusing target, and a new preview image is continuously generated for the change of the imaging definition of the focusing target in the focusing process. When focusing is started, the computer readable storage medium sends the frame of preview image acquired when the lens is at the initial position to an image processor (ISP) for processing to obtain the statistical information of the preview image, and then sends the statistical information to a focusing algorithm library (which can be executed on ISP hardware or driver software), and the focusing algorithm library calculates the distance to which the lens moves in the next step according to the hardware specification and the statistical information and drives the lens to reach the position; and then obtaining a new preview image at the position, further calculating statistical information of the new preview image, further calculating the lens position of the next step, and repeating the steps until the definition of the combined focusing target in the preview image gradually changes to a certain degree to finish focusing.
