Embodiment Construction

[0033] The present invention encompasses a method of producing a high resolution image of a target using an imaging sensor associated with an OIS module.

[0034] is depicted as figure 1 In the exemplary embodiment of the flowchart in , the method (100) includes the steps of: (120) determining the resolution requirements of the image to be generated from the target size; (140) capturing a plurality of individual low-resolution images of the target, the The minimum number of individual images captured is based on the resolution requirements determined in the step of determining resolution requirements; (150) moving the OIS module to a specific A location, the particular location is based on the resolution requirement in the step of determining resolution requirement; and (160) processing the plurality of low resolution images to generate a high resolution image.

[0035] In another exemplary embodiment of the method (100), the resolution requirement includes a resolution magni...

Abstract

An imaging device for producing a high-resolution image of a target using an imaging sensor and a method of using the imaging device are provided. The method consists of the steps of: determining a resolution requirement of an image to be produced from the size of the object; capturing a plurality of individual low-resolution images of the object, the minimum number of individual images captured being based on the determined resolution requirement step a resolution requirement; moving the OIS module to a specific position between captures of the individual low resolution images in the step of capturing the plurality of low resolution images, the specific position being based on the resolution requirement in the step of determining the resolution requirement; and processing The plurality of low-resolution images is used to generate a high-resolution image.

Description

technical field [0001] The present invention relates to image-based sensing, and in particular to the use of imaging sensors to produce high-resolution images. Background technique [0002] In general, image-based data entry, including optical character recognition and barcode scanning, and image-based sensing for process control and security, for example, suffer from limitations imposed by the quality of the input image. While every application will have different sensitivities to input image quality, common image quality issues include blur, insufficient lighting, and insufficient resolution. To reduce blur in poorly lit photos, optical image stabilization (OIS) is an increasingly common feature of mobile phone cameras. [0003] High resolution image sensors are useful in consistently obtaining quality images. However, a high-resolution sensor includes the cost of adding a camera to the camera and is not always necessary for imaging applications. [0004] Therefore, the...
