静电可变光阑和摄像模组以及控制摄像模组的进光量的方法Electrostatic variable aperture, camera module and method for controlling the amount of light entering the camera module

技术领域technical field

本发明涉及光学成像装置，特别涉及一静电可变光阑和摄像模组以及控制摄像模组的进光量的方法。The invention relates to an optical imaging device, in particular to an electrostatic variable aperture, a camera module and a method for controlling the amount of light entering the camera module.

背景技术Background technique

便携式电子设备的轻薄化的发展趋势对作为便携式电子设备的标准配置之一的摄像模组的尺寸提高了苛刻的要求，同时随着人们对于便携式电子设备的拍照质量的要求越来越高，便携式电子设备对于摄像模组的成像品质的要求也随之提高。可以理解的是，摄像模组的成像品质受到诸多因素的影响，例如像素大小、可变光圈等。现有的摄像模组的可变光圈采用多个金属片或者孔状光栅等制作的机械结构，通过复杂的机械运动或者重叠等方式实现控制遮挡光线的面积大小，从而实现进光量的调节。例如，虹膜型的可变光圈，其是由多个相互重叠的弧形薄金属片组成的具有中心圆孔的圆形结构，通过机械操作各金属片的离合能够改变虹膜型的可变光圈的中心圆孔的孔径尺寸，使得光线能够通过可变的中心圆孔射入摄像模组的光学镜头，从而实现进光量的控制。不可避免的是，一方面，由于虹膜型的可变光圈具有复杂的机械结构，另一方面，需要为机械结构的运动预留空间，故，虹膜型的可变光圈需要占用摄像模组的较大空间而导致摄像模组的尺寸无法被进一步缩小，进而导致摄像模组无法满足轻薄化的便携式电子设备的需求。为了适应便携式电子设备的轻薄化的发展趋势，摄像模组的尺寸必须被严格控制，这导致摄像模组不得不抛弃可变光圈的结构，从而导致摄像模组无法通过控制进光量来调节摄像模组拍摄的图像的明暗度和景深，更无法呈现背景虚化的图像效果。The development trend of thinner and lighter portable electronic devices imposes strict requirements on the size of the camera module, which is one of the standard configurations of portable electronic devices. The requirements of electronic devices for the imaging quality of camera modules are also increasing accordingly. It can be understood that the imaging quality of the camera module is affected by many factors, such as pixel size, variable aperture and so on. The variable aperture of the existing camera module adopts a mechanical structure made of multiple metal sheets or perforated gratings, and controls the size of the area that blocks light through complex mechanical movements or overlapping, thereby realizing the adjustment of the amount of light entering. For example, the iris-type variable aperture is a circular structure with a central hole formed by a plurality of overlapping arc-shaped thin metal sheets, and the function of the iris-type variable aperture can be changed by mechanically operating the clutch of each metal sheet. The aperture size of the central circular hole enables the light to enter the optical lens of the camera module through the variable central circular hole, thereby realizing the control of the amount of incoming light. It is unavoidable that, on the one hand, since the iris-type variable aperture has a complex mechanical structure, and on the other hand, it needs to reserve space for the movement of the mechanical structure, the iris-type variable aperture needs to occupy a relatively large area of the camera module. Due to the large space, the size of the camera module cannot be further reduced, which in turn makes the camera module unable to meet the requirements of thinner and lighter portable electronic devices. In order to adapt to the development trend of thinner and lighter portable electronic devices, the size of the camera module must be strictly controlled, which leads to the camera module having to abandon the structure of the variable aperture, which makes the camera module unable to adjust the camera module The brightness and depth of field of the image taken by the group cannot present the image effect of blurred background.

(b) When positive electricity or negative electricity is respectively applied to each blade of the blade set and a lens electrode positioned below the inner side end of each blade, the inner side end of each blade of the blade set is respectively bent and deformed upwards so as to enlarge the area of the light inlet channel, and more light is allowed to pass through the light inlet channel and then reach a photosensitive chip through an optical lens of the camera module; or when positive electricity or negative electricity is applied to each blade of the blade group, and meanwhile, when negative electricity or positive electricity is applied to the lens electrode, the inner side end of each blade of the blade group is respectively bent and deformed downwards so as to enlarge the area of the light inlet channel, and more light rays are allowed to pass through the light inlet channel and then reach the photosensitive chip through the optical lens of the camera module.

14. The light intake amount control method according to claim 13, wherein in the step (a), the light intake passage is defined by two of the blade groups, respectively an outer blade group and an inner blade group, wherein light passing through a gap formed between adjacent blades of the outer blade group enters the optical lens after being allowed to pass through a light-transmitting inner fixing ring for supporting the inner blade group.
