detailed description

In order to make the objects, technical solutions, and advantages of the present application more comprehensible, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the application and are not intended to be limiting.

1 is a flow chart of an anti-shake stroke adjustment method in one embodiment. As shown in FIG. 1, an anti-shake stroke adjustment method includes steps 102 to 106. among them:

Step 102: Detect a jitter direction of the mobile device.

The mobile device can be a device with a shooting function. The mobile device can be a mobile phone, a tablet, a wearable device, a personal digital assistant, or the like. When the mobile device is placed on the stand or the user's hand, it will produce some jitter. The direction of the camera's jitter can be detected by a gyroscope in the mobile device. Specifically, the acceleration of the mobile device on the XYZ axis can be detected by a gyroscope, and the direction of the jitter is determined according to the direction in which the acceleration is increased. The direction in which the acceleration is increased can be used as the direction of the jitter.

For example, the gyroscope detects that the initial acceleration of the mobile device on the XYZ axis is 0. When the jitter occurs, it is detected that the acceleration of the mobile device on the XY axis is 0, and the acceleration on the Z axis is 3, then the Z axis is The direction is the direction of the jitter.

In one embodiment, a plurality of images may be taken by the mobile device to be photographed, a shift between successive images may be calculated, and a wobble direction may be calculated based on the offset.

Step 104: Generate an adjustment instruction according to the shaking direction.

Specifically, the generated adjustment instruction may be an instruction that controls the movement of the lens in the same direction as the shaking direction by default, or an instruction that controls the movement of the lens.

Step 106: Control the lens to move in the same direction or in the opposite direction as the shaking direction according to the adjustment instruction to increase the movable stroke of the lens when the camera is anti-shake.

A lens is an optical device consisting of a lens in an image acquisition device of a mobile device for imaging on an imaging sensor. The movable stroke of the lens anti-shake refers to the distance that the lens can move in the same plane when photographing. The movable stroke of the lens anti-shake is the anti-shake stroke, which refers to the distance that the lens can move in the upper and lower, left and right planes.

The control lens may be in the same direction as the dithering direction along the same direction as the dithering direction, that is, the direction of the dithering is not limited to be completely identical. The opposite direction to the dithering direction may be a converging direction opposite to the dithering direction, that is, the direction opposite to the dithering direction is not limited to being completely identical.

During the photographing process, by controlling the motor of the anti-shake device, the lens can be moved to compensate the jitter, so that the optical path remains stable, the larger the movable stroke of the lens, the larger the space for the camera to compensate for the jitter, and the better the anti-shake effect.

The anti-shake stroke adjustment method detects a shaking direction of the mobile device, generates an adjustment command, and controls the lens to move in the same or opposite direction to the shaking direction according to the adjustment instruction, so as to increase the movable stroke of the lens when photographing, thereby improving Anti-shake effect.

In one embodiment, the controlling the movement of the lens in the same direction or in the opposite direction as the shaking direction according to the adjustment instruction to increase the movable stroke of the lens when photographing comprises:

Controlling the lens to move in the same direction as the shaking direction according to the adjustment instruction;

Determining whether the movable stroke of the lens is increased, and if so, continuing to control the lens to move in the same direction as the shaking direction, and if not, controlling the lens to move in a direction opposite to the shaking direction .

After the lens is controlled to move in the same direction as the shaking direction according to the adjustment command, the movable stroke of the lens is acquired, and the movable stroke of the moving lens is compared with the movable stroke of the moving lens, and if the movable stroke of the lens is moved The movable stroke larger than the moving lens indicates that the movable stroke of the lens is increased. If the movable stroke of the lens after moving is smaller than the movable stroke of the moving lens, it indicates that the movable stroke of the lens is reduced, and the moving direction is Error, stop moving, and control the lens to move in the opposite direction to the shaking direction.

The movable stroke of the lens can be detected by the distance sensor.

By controlling the lens to move in the same direction of the shaking direction firstly, if it is detected that the movable stroke is reduced, the lens is controlled to move in the opposite direction of the shaking direction in time to ensure that the movable stroke of the lens is increased to ensure the anti-shake effect is improved.

In one embodiment, the controlling the lens to move in the same direction or in the opposite direction as the shaking direction according to the adjustment instruction to increase the movable stroke of the lens when photographing comprises: according to the adjustment instruction The control lens is moved by a preset distance in the same direction or in the opposite direction as the shaking direction to increase the movable stroke of the lens when photographing.

Specifically, the preset distance may be a preset distance. The preset distance is less than or equal to the maximum distance the lens can move. The maximum distance that the lens can be moved is limited by the specific space structure of the image acquisition device in the mobile device, and the space range available for the lens to move. The lens of a mobile device usually moves on the optical axis, that is, in a spatial dimension. It can control the distance of each movement and the control is more precise.

In one embodiment, the controlling the lens to move in the same direction or in the opposite direction as the shaking direction according to the adjustment instruction to increase the movable stroke of the lens when photographing comprises: a processor of the mobile device And controlling, according to the adjustment instruction, the lens to move according to a preset amplification in the same direction or opposite direction as the shaking direction to increase the movable stroke of the lens when photographing.

Specifically, the preset increase may be a preset increased range, such as 5%, 10%, and the like. The preset increase can also be the proportional value of the jitter amplitude. The jitter amplitude is the amplitude of the jitter that can be obtained by the acceleration gain. The acceleration increase can be obtained by the ratio of the acceleration increase value to the acceleration before the increase.

The movement according to the preset increase can be moved according to the preset increase of the current movable stroke, or according to the preset increase of the maximum distance that the lens can move. The current movable stroke refers to the movable stroke of the lens before each movement.

By setting the preset increase, you can control the movement of the lens more finely.
