Patent Images

1. A camera array configured to simulate reduction in depth of field in images captured by the camera array, comprising:

  • a plurality of cameras configured to capture images of a scene, where each camera comprises;

    optics comprising at least one lens element and at least one aperture; and

    a sensor comprising a two dimensional array of pixels and control circuitry for controlling imaging parameters; and

    at least one spectral filter located within the camera, where each spectral filter is configured to pass a specific spectral band of light;

    a controller configured to control operation parameters of the plurality of cameras; and

    an image processing pipeline module;

    wherein the image processing pipeline module comprises a parallax confirmation and measurement module configured to measure parallax using images captured by the plurality of cameras and generate a depth map using the measured parallax;

    wherein the image processing pipeline is configured to select at least one distance as an “

    in best focus”

    distance and blur an image produced by the camera array based upon estimated distance information.
