    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.

    Abstract: A sequence of multiple subimages is captured by an imaging sensor organized in multiple subsets of pixels. Each of the subsets of pixels is assigned to capturing a corresponding one of the subimages. For each of the subsets of pixels, a noise level of an output of the pixels of the subset is measured. Depending on the measured noise level, an exposure time for capturing the corresponding subimage is controlled.

    Abstract: The solution disclosed herein reduces the amount of time and computational resources necessary to determine a dominant gradient direction of an image area comprising a plurality of pixels of an image. To that end, the dominant gradient direction of an image area is determined based on two gradient magnitudes determined from four sample points in the image area, where a direction of one of the gradient magnitudes is perpendicular to a direction of the other of the gradient magnitudes. The dominant gradient direction is then determined by taking the arctangent of the computed gradient magnitudes.

    Abstract: The invention is directed to systems, methods and computer program products for capturing an image using an array camera. 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.
