Abstract: A plenoptic camera device and a shading correction method thereof are provided. The plenoptic camera device includes a processor including a shading correction block configured to determine a four-dimensional axis with respect in a raw image, generate a four-dimensional profile by applying a polynomial fit with respect to the plurality of pixels in the raw image based on the four-dimensional axis, and calculate a gain using the four-dimensional profile and a non-volatile memory device configured to store the gain. Accordingly, the plenoptic camera device can remove a vignetting effect using the gain.
