AI Technical Summary

Problems solved by technology

[0005] However, in conventional optical systems, complex aspheric lenses are required to improve imaging performance and shorten the total optical length.
At this time, reflected light and stray light generated on the lens surface of complex shape appear, causing ghost or flare

Abstract

The invention provides an imaging optical system, an imaging device having the system, and an information processing device. The imaging optical system is composed of at least five lenses, the aperture is arranged on the side closest to the object, and the first lenses with positive refractive power are arranged sequentially from the object side. A lens, a second lens with negative refractive power, a third lens with positive refractive power, a meniscus-shaped fourth lens with positive refractive power and a convex surface facing the image side, and a fifth lens with negative refractive power satisfy a predetermined conditional expression .

Description

Technical field [0001] The present invention relates to an imaging optical system, an imaging device having the imaging optical system, and an information processing device. Background technique [0002] In recent years, as mobile phones, portable terminals, notebook computers, and the like have become thinner, there is a demand for a camera module that reduces the length of the optical system in these devices to the limit in the optical axis direction. In addition, due to the technological advancement of imaging components and the increase in market demand, imaging components with high pixel counts are used, and high resolution imaging lenses are required. [0003] To meet these demands, many single-focus optical systems composed of five aspheric lenses have been proposed. [0004] The configuration in which the number of lenses is 5 can improve the imaging performance while reducing the total length of the optical system. As such optical systems, Japanese Patent Application Public...
