Abstract:
A technology of acquiring and processing light field data for images is provided. A light field data acquisition apparatus includes a modulator with an attenuation pattern to spatially modulate a 4D light field for an image, and a sensor to acquire 2D signals of the spatially modulated 4D light field. By utilizing the attenuation pattern of the modulator, more spatial data may be acquired in a low angular frequency region than that acquired in a high angular frequency region.
