As shown in fig. 8, as the reflecting member 120 rotates, the image acquisition module 110 may acquire image information of different areas; as shown in fig. 9, the image acquisition module 110 may include a zoom lens, and the image in the region may be enlarged or reduced by controlling the image acquisition module 110, for example, image information of any region abc in fig. 9 may be acquired; as shown in fig. 10, the zoom lens and the reflector 120 are combined to rotate, so that local enlargement or reduction of any area in the view field range of the image acquisition device can be realized, if the focal length can be increased, the market angle becomes smaller, the image becomes clear, when the remote image needs to be acquired more clearly, the focal length needs to be increased, the market angle becomes smaller, the market range before the situation can not be fully displayed, especially the image (such as a human face) of interest can not be fully displayed, and at this time, the acquisition angle of the image acquisition module 110 is further adjusted by adjusting the angle of the reflector, so that complete and clear image information can be acquired.

In one possible embodiment, the optical axis 111 of the image acquisition module 110 is offset from the midline of the reflector 120. Such an arrangement may reduce the size of the reflector 120.

As shown in fig. 11 and 12, the image acquisition module 110 formed by drawing the solid line in fig. 12 represents the position of the image acquisition module 110 before the optical axis 111 is deviated, and the image acquisition module drawn by the broken line represents the position of the image acquisition module 110 after the optical axis 111 is deviated. It will be appreciated that in designing the position of the reflecting member 120, the field angle of the image capturing module 110 is already determined, L1, L2 are the sizes of the reflecting surfaces of the reflecting member 120 at different angles,l1=l1' +l1″ is obtainable by the sine theorem:similarly available->Due to-> Obtaining the product α is a known fixed value, so that when L2 is unchanged, ω is larger, L1 is smaller, and when ω is 90 °, L1 is smallest, and the L2 size is determined by L, so that the mirror surface dimension rotation center of the reflecting member 120 is determined by the module distance L and the angle between the reflecting member 120 and the module optical axis 111. The smaller L, the smaller the angle ω is closer to the 90 ° reflector 120.

From the following componentsIt can be seen that when ω is smaller than 90 °, L1' > L1 ", the angle of the reflector 120 is typically between 0 ° and 90 °, and the rotation center is asymmetric due to L1' > L1", and the module optical axis 111 and the rotation center are on the same horizontal line, and L1' =l1″ only when ω=90°. We can also obtain L1' =l1″ by translating the center of the optical axis 111, while also ensuring that the mirror surface of the reflecting element 120 is minimized at this angle. Because the optical axis 111 of the image capturing module 110 is offset from the center line of the reflecting member 120, that is, the optical axis 111 of the image capturing module 110 does not pass through the center line of the reflecting member 120, but the optical axis 111 is parallel to the center, the size of the reflecting member 120 can be reduced, which is more beneficial to miniaturization of the image capturing device.

In one possible embodiment, the centerline offset distance of the optical axis 111 from the reflector 120 is determined based on the field angle of the image acquisition module 110 and the tilt angle of the reflector 120 relative to the optical axis 111.

In this technical solution, a manner of determining the paranoid location of the optical axis 111 is further provided, and the offset distance is determined based on the field angle of the image acquisition module 110 and the inclination angle of the reflecting member 120 with respect to the optical axis 111, so that the paranoid of the optical axis 111 can be adapted to the performance of the image acquisition module 110 and the working state of the reflecting member 120, and the acquisition efficiency of image acquisition can be improved while the size of the reflecting member 120 is reduced.

It is understood that the inclination angle of the reflecting member 120 with respect to the optical axis 111 is an angle at which the reflecting member 120 is inclined with respect to the optical axis 111 at the extreme position.

As shown in fig. 11 and 12, in one possible embodiment, the optical axis 111 and the reflecting member 120 satisfy the following formula:

L1′-L1″＝X1+X2；

wherein L1 'is the distance between the intersection of the optical axis 111 and the reflecting member 120 and one end of the reflecting member 120, L1 "is the distance between the intersection of the optical axis 111 and the reflecting member 120 and the other end of the reflecting member 120, and L1' is greater than L1"; alpha is the angle of view; ω is the tilt angle of the reflector 120 with respect to the optical axis 111; x is the offset distance of the optical axis.

As shown in fig. 11 and 12, in this technical solution, a specific determination manner of the positional relationship between the optical axis 111 and the reflecting member 120 is further provided, so that the production and processing of the image capturing device are facilitated, the design parameters of the image capturing device are clarified, and the capturing effect of the image is improved while the size of the reflecting member 120 can be further reduced.

It will be appreciated that the mirror size when the optical axis 111 is not translatedFor L1 '+L1', when the optical axis 111 is shifted by X, the mirror size is L1 '-x1+L1' +X2. When l1' -x1=l1+x2, ω+.90°, only by translating the optical axis 111 by X. When l1 '-x1=l1 "+x2, the mirror size of l1' -l1" =x1+x2 is the smallest.

Wherein,

based on this, the positional relationship between the image capturing module 110 and the reflecting member 120 of the image capturing apparatus can be clarified.

In some examples, the driving assembly 130 may include a first electromagnetic driving member for driving the reflective member 120 to rotate in a first direction and a second electromagnetic driving member for driving the reflective member 120 to rotate in a second direction, and the first direction and the second direction are different, based on which multi-angle adjustment of the reflective member 120 may be achieved such that the image capturing direction of the image capturing module 110 may cover the field of view range of the image capturing system after being reflected by the reflective member 120 such that the image capturing device may capture close-up image information for any area within the field of view range.
