Abstract
A super-resolution image is generated from a sequence of low resolution images. In one embodiment, the image shift information is measured for each of the low resolution images using an image stabilization component of an imaging device. The shift information is used to generate the super-resolution image. In another embodiment, the blurs are calculated for each of the low resolution images and are used to generate the super-resolution image.
Claims20
A computerized method comprising:
- acquiring a plurality of low resolution images, wherein the plurality of acquired low resolution images is acquired at different focus positions;
- calculating a blur for each of the plurality of acquired low resolution images using a blur difference between different ones of the plurality of acquired low resolution images;
- and
- generating a super-resolution image from the plurality of acquired low resolution images and the calculated blurs.
A non-transitory machine readable medium having executable instructions to cause a processor to perform a method comprising:
- acquiring a plurality of low resolution images, wherein the plurality of acquired low resolution images is acquired at different focus positions;
- calculating a blur for each of the plurality of acquired low resolution images using a blur difference between different ones of the plurality of acquired low resolution images;
- and
- generating a super-resolution image from the plurality of acquired low resolution images and the calculated blurs.
A system comprising:
- a processor;
- a memory coupled to the processor though a bus;
- and
- a process executed from the memory by the processor to cause the processor to acquire a plurality of low resolution images, wherein the plurality of acquired low resolution images is acquired at different focus positions, calculate a blur for each of the plurality of acquired low resolution images using a blur difference between different ones of the acquired plurality of low resolution images and to generate a super-resolution image from the acquired plurality of low resolution images and the calculated blurs.
