Optical design of camera optics for mobile phones - ZEISS

Adv. Opt. Techn., Vol. 1 (2012), pp. 51 58 Copyright 2012 THOSS Media and De Gruyter. DOI Article Optical design of camera optics for mobile phones Thomas Steinich and Vladan Blahnik * Carl ZEISS AG , Carl- ZEISS -Strasse 22, 73447 Oberkochen , Germany * Corresponding author e-mail: Received January 9, 2012; accepted February 20, 2012 Abstract At present, compact camera modules are included in many mobile electronic devices such as mobile phones , personal digital assistants or tablet computers. They have various uses, from snapshots of everyday situations to capturing barcodes for product information. This paper presents an overview of the key design challenges and some typical solutions. A lens design for a mobile phone camera is compared to a down-scaled 35 mm format lens to demonstrate the main differ-ences in Optical design .

The distance between the image plane and the pinhole Ois the focal length f. Sometimes, the retinal plane is placed between Oand the 3D object at a distance f from O.

image formation by plane mirrors (Fig. 1), and spherical mirrors (concave and convex) as shown in Fig. 2. When parallel rays (could be from a distant object) incident on a concave mirror, the reflected rays converge to a focal point (F), hence also called converging mirror. In case of convex mirror, parallel rays are diverged
