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.
Claims20
A digital image capture device, comprising:
- a first image sensor and a first lens system having a first geometric distortion that distorts a first portion of a first field of view more than a second portion of the first field of view and that is configured to direct light from a scene onto the first image sensor;
- a second image sensor and a second lens system having a second geometric distortion that distorts a first portion of a second field of view more than a second portion of the second field of view and that is configured to direct light from the scene onto the second image sensor;
- and
- memory coupled to the first and second image sensors;
- wherein the digital image capture device is configured to:
- capture a first image of the scene with the first geometric distortion using the first image sensor and the first lens system;
- capture a second image of the scene with the second geometric distortion using the second image sensor and the second lens system;
- combine the first and the second images to generate a third image with a higher resolution than both the first and the second images, wherein the third image includes the first portion of the first field of view from the first image and the first portion of the second field of view from the second image;
- and
- store the third image in the memory.
A multi-lens camera system, comprising:
- a first lens system associated with a first geometric distortion that distorts a first portion of a first field of view more than a second portion of the first field of view and that is coupled to a first image sensor;
- and
- a second lens system associated with a second geometric distortion that distorts a first portion of a second field of view more than a second portion of the second field of view and that is coupled to a second image sensor;
- wherein the multi-lens camera system is adapted to
- capture a first image of a scene using the first image sensor and the first geometric distortion of the first lens system;
- capture a second image of the scene using the second image sensor and the second geometric distortion of the second lens system;
- combine the first and the second images to construct a third image with a higher resolution than both the first and the second images, wherein the third image includes the first portion of the first field of view from the first image and the first portion of the second field of view from the second image;
- and
- store the third image into a memory.
A multi-lens image capture method, comprising:
- capturing first image of a scene using a first lens system that includes:
- a first geometric distortion that distorts a first portion of a first field of view more than a second portion of the first field of view;
- and a corresponding first image sensor;
- capturing a second image of the scene using a second lens system that includes:
- a second geometric distortion that distorts a first portion of a second field of view more than a second portion of the second field of view;
- and a corresponding second image sensor;
- combining the first and the second images to generate a third image with a higher resolution than both the first and the second images, wherein the third image includes the first portion of the first field of view from the first image and the first portion of the second field of view from the second image;
- and
- storing the third image into a memory.
