Using captured high and low resolution images
First Claim
1. A method for producing an improved high resolution image, the method comprising:
- capturing low resolution images and a high resolution image;
combining the low resolution images to provide an aggregate low resolution image;
reducing the resolution of the high resolution image to provide an image representative of a low resolution image at a low resolution setting of the image capture device;
interpolating the representative low resolution image to provide an interpolated high resolution image;
calculating a residual image from the high resolution image and the interpolated high resolution image; and
mapping matching pixels from the aggregate low resolution image and the representative low resolution image.

Abstract
A method produces an improved high resolution image. This method includes capturing low resolution images and a high resolution image and combining the low resolution images to provide an aggregate low resolution image. The method further includes reducing the resolution of the high resolution image to provide an image representative of a low resolution image at a low resolution setting of the image capture device; interpolating the representative low resolution image to provide an interpolated high resolution image; and calculating a residual image from the high resolution image and the interpolated high resolution image. The method also includes combining the representative low resolution image and the aggregate low resolution image to provide a final low resolution image and using the final low resolution image and the residual image to provide the improved high resolution image.

8. A system comprising:
-
an image capture device configured to capture a low resolution image of a scene and a high resolution image of the scene; a response filter coupled to the image capture device, wherein the response filter is configured to combine the low resolution image with other low resolution images to provide an aggregate low resolution image; and a processor configured to reduce the resolution of the high resolution image to provide an image representative of a low resolution image at a low resolution setting of the image capture device;
interpolate the representative low resolution image to provide an interpolated high resolution image;
calculate a residual image from the high resolution image and the interpolated high resolution image; and
map matching pixels from the aggregate low resolution image and the representative low resolution image. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium having instructions stored thereon for providing an improved high resolution image using low resolution images and at least one high resolution image of a scene captured by an image capture device, the instructions comprising:
-
instructions for capturing low resolution images of a scene and a high resolution image of the scene; instructions for combining the low resolution images to provide an aggregate low resolution image; instructions for reducing the resolution of the high resolution image to provide an image representative of a low resolution image at a low resolution setting of the image capture device; instructions for interpolating the representative low resolution image to provide an interpolated high resolution image; instructions for calculating a residual image from the high resolution image and the interpolated high resolution image; instructions for estimating motion between the aggregate low resolution image and the representative low resolution image; and instructions for mapping matching pixels from the aggregate low resolution image and the representative low resolution image. - View Dependent Claims (16, 17, 18, 19, 20)
