Abstract
Spatial resolution can be improved in multi-lens digital cameras. Each lens can have the same or similar field of view, but can be associated with different geometric distortions defining, for example, a magnification at various field of view portions. A final image can be generated based on an initial image captured by each lens. Luminance information from the magnified portions of the initial images can be combined to form final image luminance information. Chrominance information from the initial images can be combined to form final image chrominance information. The final image can be generated based on the final image luminance information and the final image chrominance information.
Claims18
A multi-lens camera system, comprising:
- a first lens configured to direct light collected from a field of view onto a first image sensor portion, the collected light comprising light from a first portion of the field of view that is geometrically distorted according to a first geometric distortion function;
- a second lens configured to direct light collected from the field of view onto a second image sensor portion, the collected light comprising light from a second portion of the field of view that is geometrically distorted according to second geometric distortion function;
- and
- an image sensor comprising the first image sensor portion and the second image sensor portion and configured to capture light incident upon the first image sensor portion and the second information sensor portion to form an image, the image sensor further configured to combine luminance information from the geometrically distorted light from the first portion of the field of view and luminance information from the geometrically distorted light from the second portion of the field of view to form combined luminance information for the image.
A method for improving image resolution, comprising:
- receiving, from a first lens configured to direct light collected from a field of view onto a first image sensor portion, collected light comprising geometrically distorted light from a first portion of the field of view;
- receiving, from a second lens configured to direct light collected from the field of view onto a second image sensor portion, collected light comprising geometrically distorted light from a second portion of the field of view;
- capturing the received light;
- and
- generating image luminance information based on the captured geometrically distorted light from the first portion of the field of view and the captured geometrically distorted light from the second portion of the field of view.
