Problems solved by technology

But for the lens with continuous zoom function, the change of the lens from long focus to short focus will cause the chief ray angle (CRA) to gradually increase, but because the chief ray angle of the microlens on the image sensor is fixed at this time, it cannot be compared with The main ray angle after the lens change matches, so it is easy to cause shadows in the picture and affect the brightness uniformity of the image

Abstract

The invention relates to an image sensor, a camera module and terminal equipment. The image sensor comprises an optical array and a receiving array, wherein the optical array comprises a plurality ofoptical elements arranged in an array; each optical element comprises a shell, an electrode, a first liquid and a second liquid, wherein the electrode is fixedly opposite to the shell, the shell is provided with a cavity, the electrode can form an electric field in the cavity, the first liquid and the second liquid are arranged in the cavity in a mutually insoluble manner, the first liquid and thesecond liquid are transparent liquid respectively, a refracting interface is formed between the first liquid and the second liquid, and the electrode can drive at least one of the first liquid and the second liquid to change the curvature of the refracting interface; and the receiving array comprises a plurality of receiving units arranged in an array, wherein any optical element corresponds to at least one receiving unit in an optical axis direction, and the receiving unit is used for receiving light rays passing through the optical element. The optical elements can be used for adjusting a chief ray angle to be matched with a chief ray angle of a zoom lens group in order to improve the imaging quality.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to an image sensor, camera module and terminal equipment. Background technique [0002] For a traditional image sensor, a microlens array is arranged on the side of the receiving surface to focus the incident light, thereby improving the photoelectric conversion efficiency of the photodiode. But for the lens with continuous zoom function, the change of the lens from long focus to short focus will cause the chief ray angle (CRA) to gradually increase, but because the chief ray angle of the microlens on the image sensor is fixed at this time, it cannot be compared with The main ray angle after the lens change matches, so it is easy to cause shadows in the picture and affect the brightness uniformity of the image. Contents of the invention [0003] Embodiments of the present application provide an image sensor capable of adjusting a chief ray angle, a camera module, and...
