Abstract
Camera systems and methods for gigapixel computational imaging are provided. In some embodiments, the camera system comprises: a ball lens, an array of image sensors disposed at a distance from the ball lens, the array of image sensors configured to acquire images from light that passes through the ball lens; and a processor configured to deblur and stitch the images captured by the array of image sensors to generate a gigapixel image.
Claims20
A camera system for high resolution imaging, the camera system comprising:
- a ball lens;
- an array of image sensors disposed at a distance from the ball lens, the array of image sensors configured to acquire images from light that passes through the ball lens;
- and
- a processor configured to deblur and stitch the images captured by the array of image sensors to generate a gigapixel image.
A camera system for high resolution imaging, the camera system comprising:
- a ball lens having a spherical image plane, wherein the spherical image place is approximated by a tessellated regular polyhedron;
- a plurality of image sensors disposed on surfaces of the tessellated regular polyhedron, wherein the plurality of image sensors acquire images from light that passes through the ball lens;
- and
- a processor configured to deblur and stitch the images captured by the plurality of image sensors to generate a gigapixel image.
A method for high resolution imaging, the method comprising:
- detecting a plurality of images from an array of image sensors, wherein each of the plurality of image sensors captures light that passes through a ball lens and an array of relay lenses;
- deblurring, using a processor, the plurality of images detected by the array of image sensors;
- and
- stitching, using the processor, the plurality of deblurred images to generate a gigapixel image.
