Abstract
In a method for designing a binary phase filter to expand depth of field and for reconstructing images performed by an electronic device according to an embodiment of the present disclosure, the method includes: obtaining images for each depth for a test image based on a binary phase structure set in the binary phase filter; obtaining reconstructed images for each depth by reconstructing the images for each depth based on a model trained to reconstruct an input image; calculating a loss value of the reconstructed images for each depth by comparing the reconstructed images for each depth with the test image; and updating the binary phase structure until the loss value becomes less than or equal to a predefined value.
