Abstract
A color preview image is generated, preferably in real-time, for a plenoptic imaging system. The raw plenoptic image has a structure containing superpixels and also contains different color channels. For a principal color channel, a center view is generated by determining the pixel value for a center view of the superpixel, i.e. at the centroid of the superpixel. For each of the other color channels, the ratio of that color channel to the principal color channel is calculated for each superpixel. A center view for each non-principal color channel is determined by multiplying the color ratios times the pixel values for the principal color center view. These center views for the principal and non-principal color channels are combined into a color preview image. The calculations preferably can be performed in real-time at video rates.
