Imaging device for producing high resolution images using subpixel shifts and method of using same
First Claim
1. A method, comprising:
- determining, from a target size, resolution requirements of an image to be produced;
capturing multiple individual lower resolution images of a target, a number of individual images captured being based upon the determined resolution requirements;
moving an optical image stabilization (OIS) module to specific positions between the capturing of the individual lower resolution images, the specific positions being based upon the determined resolution requirements; and
processing the multiple lower resolution images to produce a higher resolution image.

Abstract
An imaging device for producing a high resolution image of a target with an imaging sensor and a method using the same is provided. The method is comprised of the steps of: determining, from the target size, resolution requirements of the image to be produced; capturing multiple individual low resolution images of the target, a minimum number of individual images captured being based upon the resolution requirements determined in the determining resolution requirements step; moving the OIS module to specific positions between the capturing of the individual low resolution images in the capturing multiple low resolution images step, the specific positions being based upon the resolution requirements in the determining resolution requirements step; and processing the multiple low resolution images to produce a high resolution image.

12. A device, comprising:
-
an imaging sensor; an optical image stabilization (OIS) module, the imaging sensor and the OIS module being associated; and a processor communicatively linked to the OIS module and the imaging sensor; the processor being configured to; determine resolution requirements of an image to be produced from a target size; instruct the imaging sensor how many lower resolution images should be captured based upon the resolution requirements; capture multiple images of the target based upon the instructions from the processor; determine movement of the OIS module to specific positions while the imaging sensor is capturing multiple images based upon the determined resolution requirements of the image and to communicate the determined movement to the OIS module; the OIS module being configured to move to the specific determined positions based upon the communications from the processor while the imaging sensor is capturing multiple images of the target, the OIS module moving between the determined positions between image captures by the imaging sensor; and the processor is configured to process the multiple lower resolution images to produce a higher resolution image. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
