PORTABLE DEVICE WITH IMAGE SENSOR AND QUAD-CORE PROCESSOR FOR MULTI-POINT FOCUS IMAGE CAPTURE
First Claim
1. A portable device comprising:
- an image sensor with adjustable focal length for sensing a scene; and
,a quad-core processor with four processing units and an image sensor interface incorporated onto a single chip;
wherein,the image sensor interface is configured to provide the four processing units with image data from the image sensor, and the four processing units are configured to divide the image data into selected regions of the scene and simultaneously derive an image sharpness metric for each of the regions, such that an optimal focal length for each of the selected regions is determined when the image sharpness metric for that region of the scene is above a threshold, and an image of the scene is captured at each of the optimal focal lengths.

Abstract
A multi-core processor is used in a portable device that has first and second image sensors spaced from each other for capturing images of a scene from slightly different perspectives. The multi-core processor has a first image sensor interface for receiving data from the image sensor, a second image sensor interface for receiving data from the second image sensor, multiple processing units and, the four processing units and the first and second sensor interfaces being integrated onto a single chip. The processing units are configured to simultaneously process the data from the first and second image interfaces to generate stereoscopic image data.
