Embodiment Construction

[0040] This specification includes references to "one embodiment" or "an embodiment." The appearances of the phrase "in one embodiment" or "in an embodiment" are not necessarily referring to the same embodiment. Particular features, structures or characteristics may be combined in any suitable way consistent with the disclosure.

[0041] "include". The term is open-ended. As used in the appended claims, the term does not exclude additional structure or steps. Consider a claim that states: "An apparatus comprising one or more processor units...". This claim does not preclude said apparatus from including additional components (eg network interface units, graphics circuits, etc.).

[0042] "is configured as". Each unit, circuit or other component may be described or claimed as being "configured to" perform one or more tasks. In these contexts, "configured to" is used to imply structure by indicating that the unit / circuit / component includes structure (eg, circuitry) that pe...

Abstract

A folded lens system may include multiple lenses with refractive power and a light path folding element. Light entering the camera through lens(es) on a first optical path or axis is refracted to the folding element, which changes direction of the light onto a second optical path or axis with lens(es) that refract the light to form an image plane at a photosensor. At least one of the object side and image side surfaces of at least one of the lens elements may be aspheric. Total track length (TTL) of the lens system may be 16.0 mm or less. The lens system may be configured so that the telephoto ration |TTL / f| is greater than 1.0. Materials, radii of curvature, shapes, sizes, spacing, and aspheric coefficients of the optical elements may be selected to achieve quality optical performance and high image resolution in a small form factor camera.

Description

[0001] priority information [0002] This application claims the benefit of priority to U.S. Provisional Application Serial No. 61 / 949,898, filed March 7, 2014, entitled "FOLDED LENS SYSTEMS," the contents of which are hereby incorporated by reference in their entirety . technical field [0003] The present disclosure relates generally to camera systems, and more particularly, to lens systems for small form factor cameras. Background technique [0004] The advent of small mobile multipurpose devices such as smartphones and tablets or tablet devices has led to a need for high resolution, small form factor cameras for integration in the devices. However, due to limitations of conventional camera technology, the traditional small cameras used in these devices tend to capture images at lower resolution and / or lower image quality than can be achieved using larger, higher quality cameras. Achieving higher resolution with a small package size camera generally requires the use of ...
