Abstract: Provided is a camera optical lens including seven lenses sequentially from object side to image side: first lens having negative refractive power, second lens having positive refractive power, third lens having positive refractive power, fourth lens having positive refractive power, fifth lens having negative refractive power, sixth lens having positive refractive power, seventh lens having negative refractive power and with object and image side surfaces being free-form surfaces. Focal length of camera optical lens is f; focal length of first lens is f1, focal length of third lens is f3, focal length of fourth lens is f4; refractive index of third lens is nd3; refractive index of sixth lens is nd6; refractive index of seventh lens is nd7, and following relational expressions are satisfied: ?1.52?f1/f??1.38; 1.56?nd3?1.59; 1.53?nd6?1.81; 1.61?nd7?1.67; 2.04?f3/f4?2.27.

Abstract: An image processing system and an imaging device are provided. The image processing system includes a circuit board, an ambient light sensor, a light guide, a camera sensor and a camera lens. The ambient light sensor is integrated on the circuit board. An output end of the light guide is connected to the ambient light sensor to guide light to a detecting part of the ambient light sensor. The camera sensor is integrated on the circuit board. The camera lens is connected to the camera sensor. In the present disclosure, light guide is optically coupled with the ambient light sensor, such that a field of view of the ambient light sensor can be controlled to enhance color performance. Further, the light guide can provide spatial selectivity for the ambient light sensor while improving system integration and minimizing impact on appearance of the imaging device.

Abstract: A camera module includes a circuit board; an image sensor mounted on the circuit board and electrically connected with the circuit boards, the image sensor comprising an array of focal planes; a barrel mounted on the circuit board with a cavity formed between the barrel and the circuit board, the image sensor being received in the cavity; and a lens stack array mounted to the barrel and spaced from the image sensor, the lens stack array comprising a plurality of first lens stacks, second lens stacks, third lens stacks, each of the lens stacks corresponding to one of the focal planes. The first lens stacks, the second lens stacks and the third lens stacks have different field of view and are combined in a single camera module, which enables a compact solution in a form of single camera module that traditionally requires multiple camera modules.
