System and method to selectively combine images

Abstract

Systems and methods to selectively combine images are disclosed. In a particular embodiment, an apparatus includes a registration circuit configured to generate a set of motion vector data based on first image data corresponding to a first image and second image data corresponding to a second image. The apparatus includes a combination circuit to selectively combine the first image data and adjusted second image data that corresponds to the second image data adjusted according to the motion vector data. The apparatus further includes a control circuit to control the combination circuit to generate third image data.

Description

I. FIELD [0001]The present disclosure is generally related to a system and method to selectively combine images.II. DESCRIPTION OF RELATED ART [0002]Advances in technology have resulted in smaller and more powerful computing devices. For example, there currently exist a variety of portable personal computing devices, including wireless computing devices, such as portable wireless telephones, personal digital assistants (PDAs), and paging devices that are small, lightweight, and easily carried by users. More specifically, portable wireless telephones, such as cellular telephones and internet protocol (IP) telephones, can communicate voice and data packets over wireless networks. Further, many such wireless telephones include other types of devices that are incorporated therein. For example, a wireless telephone can also include a digital still camera, a digital video camera, a digital recorder, and an audio file player. Such wireless telephones can process executable instructions, in...

AI Technical Summary

Benefits of technology

[0005]Multiple images may be combined using a configurable image processing architecture that performs registration and combination of images to overcome issues that may occur in individual images. A control unit may adjust operation of a hierarchical image registration and a hierarchical image combination to enable various effects of combining the input image data. For example, a first two sets of image data may be combined for hand jitter reduction with reduced ghosting, a next two sets of image data may be combined to generate an enhanced depth of field image, and other sets of images may be combined to generate a high dynamic range image.

Problems solved by technology

Captured image data may suffer from one or more issues such as shifting errors due to hand jitter, movement of objects in the image, overexposure, underexposure, poor focus in the near field or far field, lateral chromatic aberrations, and geometric distortions.
