Abstract
An apparatus includes an optical sensor configured to capture a plurality of input images. The apparatus also includes an analog circuit configured to produce a difference of Gaussians image for each of the input images. The apparatus further includes at least one processor configured to (i) determine motion error in the input images based on comparing the difference of Gaussians image and (ii) adjust at least some of the input images based on the determined motion error.
Claims20
An apparatus comprising:
- an optical sensor configured to capture a plurality of input images;
- an analog circuit configured to produce a difference of Gaussians image for each of the input images;
- and
- at least one processor configured to (i) determine motion error in the input images based on comparing the difference of Gaussians images and (ii) adjust at least some of the input images based on the determined motion error.
A method comprising:
- capturing, using an optical sensor, a plurality of input images;
- producing, using an analog circuit, a difference of Gaussians image for each of the input images;
- determining, using at least one processor, motion error in the input images based on comparing the difference of Gaussians images;
- and
- adjusting, using the at least one processor, at least some of the input images based on the determined motion error.
A non-transitory computer readable medium containing instructions that when executed cause a signal processor to:
- obtain, using an optical sensor and an analog circuit, a difference of Gaussians image for each of a plurality of input images;
- determine motion error in the input images based on comparing the difference of Gaussians images;
- and
- adjust at least some of the input images based on the determined motion error.
