Patent Description:
Periscope cameras have become a necessary configuration for mobile devices. A periscope camera deflects an incident light via a mirror, so that the lens of the periscope camera does not need to face the incident light directly. In the case where the periscope camera is applied to a terminal such as a mobile phone, the lens may be set parallel to the body of the terminal, thereby avoiding a situation that the lens protrudes from the body.

The periscope camera is capable of achieving large-magnification optical zoom. It may cooperate with the main camera and ultra-wide-angle matrix camera to achieve higher magnification optical zoom, providing an excellent experience for image shooting. Related technologies are known from <CIT>, <CIT>, <CIT> and <CIT>.

As shown in <FIG>, the first magnetic sensing component and the second magnetic sensing component are coupled to the movement control component <NUM>, and the movement control component <NUM> receives sensing data of the first magnetic sensing component and the second magnetic sensing component.

The magnetic field generated by the first coil attracts or repels the first magnetic component to drive the lens <NUM> to move, and a moving position of the lens <NUM> may be detected by the first magnetic sensing component provided corresponding to the first magnetic component.

In some embodiments, the image acquisition module <NUM> further includes:
a motion detection unit <NUM>, coupled to the movement control component <NUM> and configured to detect a motion of the image acquisition module <NUM> and output a motion detection signal.

The movement control component <NUM> is configured to calculate corresponding motion correction amount according to the motion detection signal, and adjust the first driving signal and/or the second driving signal based on the motion correction amount.

As shown in <FIG>, the motion detection unit <NUM> is coupled to the movement control component <NUM>, and the movement control component <NUM> receives sensing data of the motion detection unit <NUM>.

The motion detection unit <NUM> may be an acceleration sensor or the like. The motion detection unit <NUM> may be used for detecting a motion state of the image acquisition module <NUM>. For example, the motion detection unit <NUM> may detect accelerations of the image acquisition module <NUM> in different directions.

During the use of the image acquisition module <NUM>, the motion state such as shaking may occur, which affects the imaging quality of the image acquisition module <NUM>. Here, the motion detection unit <NUM> may adjust the first driving signal and/or the second driving signal to drive the lens <NUM> and/or the light transmission component <NUM> to offset the motion of the image acquisition module <NUM>. In this way, the imaging quality may be improved.

In some embodiments, as shown in <FIG>, the image acquisition module <NUM> further includes:.

The image sensor component <NUM> may be a complementary metal oxide semiconductor (CMOS) image sensor chip or the like, and is used for performing photoelectric conversion on the ambient light acquired by the lens <NUM> to convert it into a digital signal to form a digital image.

The image processing component <NUM> may perform image processing and analysis on the digital image acquired by the image sensing component <NUM> to determine the image quality parameter of the image. The image quality parameter may characterize the imaging quality of the image acquired by the image acquisition module <NUM>. The image quality parameter may include resolution, color depth, image distortion, and anti-shake effect.

Due to a change of a focal length of the lens <NUM> and the shake that occurs when the image acquisition module <NUM> acquires the image, image quality parameters of digital images formed by the image sensing component <NUM> are different. Different image quality parameters have different image qualities. For example, an edge peak contrast of an object on the image acquired by the image sensing component <NUM> when the lens <NUM> is successfully focused is higher than that of the object on the image acquired by the image sensing component <NUM> when the lens <NUM> fails to focus.

The image processing component <NUM> may instruct the movement control component <NUM> to adjust positions of the lens <NUM> and the light transmission component <NUM> based on the image quality parameter until the image quality parameter meets a predetermined condition.

In some embodiments, the image quality parameter includes: an image suppression ratio.

The image suppression ratio may characterize the image quality of the image when the image acquisition module <NUM> occurs the shake. As shown in <FIG>, when the image acquisition modules <NUM> are in different states, imaging distances between two pixels are different, that is, actual ambient light that each pixel can distinguish is different. Here, the different states may include: the image acquisition module <NUM> is in a static state, the image acquisition module <NUM> is in a dynamic state without an anti-shake function, the image acquisition module <NUM> is in the dynamic state with the anti-shake function, or the like. The image suppression ratio may be used for characterizing the effect of the anti-shake function. When a maximum image suppression ratio is detected, it indicates that the lens <NUM> and/or the light transmission component <NUM> are in a better imaging position at this time.

The image suppression ratio may be expressed by formula (<NUM>): <MAT>
where D-OISon represents an imaging distance between two pixels when the optical image stabilization (OIS) function is on, D-OISoff represents an imaging distance between two pixels when the OIS function is off, and D-static represents an imaging distance between two pixels in a static state (e.g., when the mobile phone is in the static state).

In some embodiments, there are two first moving components <NUM>, and these two first moving components <NUM> are distributed on both sides of the lens <NUM> with the optical axis of the lens <NUM> as a symmetry axis.

Here, there may be two first moving components <NUM> distributed on both sides of the lens <NUM> with the optical axis as the symmetry axis. In this way, when the first moving component <NUM> moves the lens <NUM>, pushing forces may be applied from both sides of the lens <NUM> to keep the lens <NUM> moving linearly along the optical axis, which reduces the shaking of the lens <NUM> caused by an displacement in an non-optical axis direction generated due to an unilateral force of the lens <NUM>, thereby improving the imaging quality.

In some embodiments, there are three second moving components <NUM>, and these three second moving components <NUM> are located on a first side, a second side, and a third side of the light transmission component <NUM>, respectively. The first side and the second side are distributed with the optical axis of the lens <NUM> as the symmetry axis, and the third side is perpendicular to the optical axis.

Here, there may be three second moving components <NUM>, and in this case, two second moving components <NUM> are arranged on both sides of the light transmission component <NUM> parallel to the optical axis with the optical axis as the symmetry axis, and the remaining second moving component is arranged on a side perpendicular to the optical axis. In this way, when the second moving component <NUM> moves the light transmission component <NUM>, the forces applied to the light transmission component <NUM> may be kept uniform when the light transmission component <NUM> is rotating, which reduces the shaking of the light transmission component <NUM> caused by the displacement in the non-optical axis direction generated due to the uneven forces applied to the light transmission component <NUM>, thereby improving the imaging quality.

In some embodiment, the light transmission component <NUM> includes: at least one mirror.

The light transmission component <NUM> may deflect the ambient light via the mirror. The mirror here may be a flat mirror or a reflective prism.

Here, the image acquisition module <NUM> may be a periscope camera module inside the terminal such as the mobile phone. In the image acquisition module <NUM>, the lens <NUM> is used for acquiring the ambient light transmitted by the light transmission component <NUM> for optical imaging. The lens <NUM> may include a plurality of optical lenses.

The first moving component <NUM> includes at least one first coil and at least one first magnetic component (not shown in the figure). The first magnetic component may be a magnet, and the at least one first magnetic component is located on the lens <NUM>. The first magnetic component may include an S pole and an N pole, and the S pole and the N pole may be arranged parallel to the optical axis X. The first coil may be arranged on the housing of the image acquisition module <NUM>. A driving signal of the first coil may be provided by an internal circuit of the image acquisition module <NUM> or may be provided by an external circuit of the image acquisition module <NUM>. The first coil may drive the first magnetic component and the lens <NUM> to move by generating a magnetic field that attracts or repels the magnetic field of the first magnetic component.

Exemplarily, a wire of the first coil may be wound with a twisted pair to avoid an influence of a stray magnetic field on a main magnetic field (e.g., a direction of the main magnetic field). The first coil may adopt a series structure, and the first coil may control a current of the image acquisition module <NUM> through wiring of a soft circuit board around the image acquisition module <NUM>.

In this way, the lens <NUM> and the light transmission component <NUM> are provided with moving components that may move the lens <NUM> and the light transmission component <NUM>, respectively, which may realize, so that the lens <NUM> and the light transmission component <NUM> may move, thereby realizing the zooming and anti-shake functions of the image acquisition module <NUM>, improving the imaging quality and improving user shooting experience.

In some embodiments, the image acquisition module <NUM> further includes:
a motion detection unit <NUM>, coupled to the movement control component <NUM> and is configured to detect a motion of the image acquisition module <NUM> and output a motion detection signal.

During the use of the image acquisition module <NUM>, the motion state such as shaking may occur, which affects the imaging quality of the image acquisition module <NUM>. Here, the motion detection unit <NUM> may adjust the first driving signal and/or the second driving signal to drive the lens <NUM> and/or the light transmission component <NUM> to offset the motion of the image acquisition module <NUM>. In this way, the anti-shake function may be achieved, and the imaging quality may be improved.

In this way, the lens and/or the light transmission component are adjusted based on the image quality parameter, thereby improving the imaging quality.

Here, there may be three second moving components <NUM>, and in this case two second moving components <NUM> are arranged on both sides of the light transmission component <NUM> parallel to the optical axis with the optical axis as the symmetry axis, and the remaining second moving component is arranged on a side perpendicular to the optical axis. In this way, when the second moving component <NUM> moves the light transmission component <NUM>, the forces applied to the light transmission component <NUM> may be kept uniform when the light transmission component <NUM> is rotating, which reduces the shaking of the light transmission component <NUM> caused by the displacement in the non-optical axis direction generated due to the uneven forces applied to the light transmission component <NUM>, thereby improving the imaging quality.

A specific example is provided below in conjunction with any of the above embodiments:.

The periscope camera module has become an inevitable trend in devices. The magnet is arranged on the lens. North and south poles of each magnet is distributed left and right. Each magnet corresponds to a copper wire coil. The copper wire is wound with the twisted pair to avoid the influence of the stray magnetic field on the main magnetic direction. The multiple copper wire coils belong to the series structure. A current of the coil is controlled by the wiring of the soft circuit board around the lens, and a pulse width modulation method (PWM) is used to achieve different current adjustments. Different current modulations may achieve desired displacement by driving. Displacement compensation of the lens is achieved according to the cooperation of the left and right magnets and upper and lower magnets with the magnetic fields generated by the corresponding coils. Whether the driving is in place at the moment is determined according to the image suppression ratio acquired by the image sensing component as a closed-loop control.

As shown in <FIG>, the light passes through the lens, the lens is designed with the magnet, and there are coils that generate magnetic fields in multiple directions X, Y, and Z around the lens. When the movement in a certain direction is needed, the current is applied to two coils in the certain direction to generate the magnetic field by the coils. The magnetic field generated by the coil attracts or repels the magnetic field of the magnet to drive the lens to move. The moving position of the lens is detected by a hall sensor, and an displacement of the movement is in a linear relationship with the change of the magnetic field, as shown in <FIG>. After the adjustment of the lens, the imaging is performed through the image sensing component. According to the image suppression ratio as shown in <FIG>, when the movement of the lens is adjusted, the image suppression ratio will change. When the maximum image suppression ratio is detected, the lens position is adjusted in place.
