Camera lens and image pick-up module set comprising lens

Abstract

The present invention relates to a camera lens. The camera lens comprises an independent first lens unit and at least one independent second lens unit fixedly connected with the first lens unit, the first lens unit and the second lens unit are sequentially arranged, and the first lens unit or the second lens unit is provided with a variable-focal length lens. According to the camera lens, the variable-focal length lens is adopted, the close-range imaging of the camera lens is achieved, additional lenses or redundant components are not required, hardware costs can be saved, and the quantity ofhardware can be decreased; the lens achieves fast and convenient focal length variation; the design requirements of the camera lens are lowered, and the imaging of the image pick-up module set is moreclear; the lens is adopted, so that the continuous focal length variation of the image pick-up module set can be realized, and the imaging quality of the image pick-up module set is good; and the useof the lens is equivalent to the replacement of a corresponding fixed-focus lens in the camera lens, so that the increase of the number of lenses in the camera lens can be avoided, and therefore, theincrease of the overall height or size of the camera lens can be avoided.

Description

technical field [0001] The invention relates to a lens, in particular to a lens with a variable focal length lens; and a camera module including the lens. Background technique [0002] The camera module of the current mobile phone realizes the optical zoom function, and generally adopts the periscope method. This method uses two or more groups of long and short focal length lenses to achieve optical zoom of a specific magnification. At the same time, the digital zoom is integrated through a certain algorithm to achieve the purpose of zooming. In the prior art, the zooming of individual camera modules achieves the zoom function of a single lens through the movement of the lens inside the lens to achieve the focal length change. However, due to the size limitation of mobile phones, this solution is difficult to be widely used, and the market value is not high. In addition, when shooting close range, it mainly depends on the design strength of the lens. Due to the limitation...
