Problems solved by technology

However, with the continuous development of portable electronic products such as smartphones, higher requirements are put forward for imaging lenses, especially for situations such as insufficient light (such as rainy days, dusk, etc.), hand shake, etc., so the F number of 2.0 or above Can no longer meet higher-level imaging requirements

Abstract

The lens and the seventh lens have light focusing. The third lens and the sixth lens have positive light focus. The side of the sixth lens is concave surface, and the image side of the third lens is convex surface., Surface type, curvature radius, the center thickness of the light shaft, the axis spacing between each lens, etc., so that the camera optical lens group is suitable for each electronic imaging module device, and the seven -lens imaging system of the camera optical lens group.The combination of the optimization range of the facial shape of the lens and the optical parameters. This imaging system can effectively shorten the total length of the imaging lens when improving imaging quality, with high resolution of high pixels, providing small portable portable electronic imaging imagingModule device is higher in imaging quality.

Description

technical field [0001] The invention relates to the technical field of imaging equipment production, in particular to an imaging optical lens group. Background technique [0002] In recent years, with the continuous advancement of technology, mobile electronic devices such as smart phones, tablet computers, driving recorders, and sports cameras have become more popular. While mobile electronic devices bring great convenience, people have higher and higher requirements for mobile electronic device terminals, that is, electronic imaging module devices, such as electronic products with photography functions, and are constantly pursuing thinner, lighter, more portable, and more efficient. and a better user experience. [0003] For example, in the process of taking pictures with electronic products with photography functions, people hope to take pictures with high resolution and high final color reproduction, preferably without any deviation from the actual scene. Driven by thi...
