Optical imaging system

#The following description relates to an optical imaging system.

#In mobile terminals, camera modules have come to be provided as a standard component, enabling video calls and image capture. In addition, as the functionality of camera modules in portable terminals has gradually increased, demand for high-resolution, high-performance camera modules in portable terminals has also increased. However, because portable terminals are becoming miniaturized and lightweight, limitations in implementing high-resolution and high-performance camera modules have been encountered.

#In order to implement miniature high-performance modules, the lenses of camera modules have been formed of a plastic material lighter than glass, and optical imaging systems include five or more lenses to implement high resolution. Other considerations must also be factored into the design in the case of camera modules installed on the front surfaces of portable terminals. Such camera modules use a relatively wide angle of view to capture wide-range images.

#FIG. 1 is a lens configuration diagram illustrating an optical imaging system according to a first example.

#FIG. 2 is a set of graphs illustrating curves representing aberration characteristics of the optical imaging system illustrated in FIG. 1.

#FIG. 3 is a table listing lens characteristics of the optical imaging system illustrated in FIG. 1.

#Throughout the drawings and the detailed description, the same reference numerals refer to the same elements, where applicable. The drawings may not be to scale, and the relative size, proportions, and depiction of elements in the drawings may be exaggerated for clarity, illustration, or convenience.

#The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses, and/or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatuses, and/or systems described herein will be apparent after an understanding of the disclosure. The sequences of operations described herein are merely examples, and are not limited to those set forth herein, but may be changed, as will be apparent after an understanding of the disclosure, with the exception of operations necessarily occurring in a certain order. Also, descriptions of functions and constructions that are well known may be omitted for increased clarity and conciseness.

#The features described herein may be embodied in different forms, and should not be construed as being limited to the examples described herein.
