IMAGE ACQUISITION METHOD AND APPARATUS WITH MEMS OPTICAL IMAGE STABILIZATION (OIS)

摘要

An image acquisition sensor of a digital image acquisition apparatus is coupled to imaging optics for acquiring a sequence of images. Images acquired by the sensor are stored. A motion detector causes the sensor to cease capture of an image when the degree of movement in acquiring the image exceeds a threshold. A controller selectively transfers acquired images for storage. A motion extractor determines motion parameters of a selected, stored image. An image re-constructor corrects the selected image with associated motion parameters. A selected plurality of images nominally of the same scene are merged and corrected by the image re-constructor to produce a high quality image of the scene.

主权项

1. A digital image acquisition apparatus, comprising:
an image acquisition sensor coupled to imaging optics for acquiring a sequence of images; an image store for storing images acquired by said sensor; an optical image stabilization sub-system to optically compensate for device motion during image acquisition up to a pre-determined motion threshold; a motion detector for causing said sensor to cease capture of an image when a degree of movement in acquiring said image exceeds a threshold; a controller for selectively transferring said image acquired by said sensor to said image store and resetting said image sensor and re-aligning the imaging optics with a main optical axis; and an image merger for merging a selected plurality of images nominally of a same scene to produce a high quality image of said scene.
