A method comprises determining an application associated with capturing an image using an array camera, wherein the array camera comprises a first sensor and at least one second sensor, wherein the first sensor comprises a red filter, a green filter, and a blue filter, and wherein each second sensor comprises a red filter, a green filter, or a blue filter; determining whether the application requires the image to have a first resolution equal to or greater than a predetermined resolution; determining whether the application requires depth information associated with the image; and in response to determining the application does not require the image to have the first resolution and does not require depth information, activating the first sensor, and capturing the image using the first sensor.

Abstract: The invention is directed to determining compensation distance for capturing an image in a zoom mode using a camera. An exemplary method comprises determining the camera is in a non-zoom mode; receiving first depth information associated with an object in the image when the camera is in the non-zoom mode; receiving first angle information associated with the object in the image when the camera is in the non-zoom mode; switching from the non-zoom mode to a zoom mode; receiving second angle information associated with the object in the image when the camera is in the zoom mode; determining a compensation distance for capturing the image of the object in the zoom mode based on the first depth information, the first angle information, and the second angle information; and generate an image based on the compensated distance.

Abstract: On the basis of a first configuration of one or more imaging sensors, first video data is captured at a first frame rate and a first resolution and second video data is captured at a second frame rate and a second resolution. The second frame rate is higher than the first frame rate and the second resolution is lower than the first resolution. Further, an amount of motion is detected in the captured second video data. On the basis of the detected amount of motion, the at least one imaging sensor is switched to a second configuration. On the basis of the second configuration, third video data is captured at a third frame rate and a third resolution. The third frame rate is higher than the first frame rate and the third resolution is higher than the second resolution.

Abstract: A method and apparatus for recording a composite image from a lens array are disclosed. A first composite image is recorded using a first lens providing imaging data in a first color, a second lens providing imaging data in a second color, and a third lens providing imaging data in a third color, wherein the first, second, and third colors are different colors. A second composite image is recorded using the first lens, a fourth lens providing imaging data in the second color, and a fifth lens providing imaging data in the third color. The first and second composite images are compared to identify color fringed areas. Based on the relative size and location of the color fringed areas in the first and second composite images, a de-fringing algorithm is applied to at least one of the composite images to mitigate the color fringing in the color fringed areas.
