Patent ID: 10332269

Abstract:
In one aspect, a plenoptic imaging system includes imaging optics, a microlens array and a sensor array. A method for color correction of views captured by the plenoptic imaging system includes the following. A plenoptic image of an object captured by the plenoptic imaging system is accessed. The plenoptic image includes many superpixels. Each superpixel includes many subpixels corresponding to different views of the object. The subpixels are of at least two different colors. An initial color view of the object is generated from the plenoptic image. The initial color view includes color pixels. Pixel-wise color correction factors are applied to the color pixels in the initial color view, thereby generating a corrected color view. The pixel-wise color correction factors are determined based on an initial color view generated for a calibration object of known color, as captured by the plenoptic imaging system.
