Summary: | The invention discloses a lossless full-focusing method and device for a light field camera, and the method comprises the steps: determining a central pixel point of each macro pixel in an original light field image, calculating a parallax value between the central pixel point of each macro pixel and a corresponding non-central pixel point, calculating the displacement step length of each macro pixel, then converting the non-central pixel point to a frequency domain, moving each non-central pixel point in the frequency domain according to a displacement step length, converting the moved non-central pixel point to a spatial domain, reconstructing the moved non-central pixel point and a corresponding central pixel point to form a new macro pixel so as to obtain a new light field image, and finally, carrying out dimension reduction processing on the new light field image to obtain a two-dimensional lossless full-focusing image, thereby improving the focusing effect.
