Apparatus for camera module of electronic equipment and associated method

Abstract

A camera module is provided for an electronic device, such as a wireless mobile station or standalone device. The camera module includes a low F-stop lens assembly that is translatable into a desired position. An image of a subject is provided to an EDOF assembly, including a sensor assembly, and an extended-depth-of-field processor. The extended-depth-of-field processor provides for formation of a resultant, recorded image that exhibits improved depth of field characteristics.

Description

technical field [0001] The present disclosure generally relates to the manner in which an image of a subject is recorded by a camera module, such as that of a portable mobile station or other wireless device. More specifically, the present disclosure relates to apparatus and associated methods by which an image of an object focused to a focus position by a translatable camera lens is recorded at an extended depth-of-field element using extended depth-of-field image portion selection. [0002] Low F-stop panning camera lens used with extended depth-of-field image formation, where low F-stop panning camera lens allows for improved performance in low-light environments, relative to conventional digital cameras The depth-of-field characteristics of the resulting recorded image are improved for the recording element. Background technique [0003] Recent years have witnessed many changes brought about by technological advancements. As a result of such technological advances, for...

Problems solved by technology

This limitation is especially problematic in low-light environments, where lesser amounts of light energy are incident on the available pixels, and the resulting recorded image quality is degraded

[0010] The size constraints on the camera module also limit the size of the allowed camera lens

And, because of this limitation, the use of low f-stop camera lenses is limited for a lens of a given focal length

[0011] Accordingly, existing size-limited camera modules, such as those used in portable wireless devices, suffer from various deficiencies that limit the quality of recorded images that can be obtained
