Information processing device, method and storage medium for reconstructing an image including an interference fringe image using local area information

A method of operating an information processing device that reconstructs an original image including an interference fringe image of at least one object to be observed, the method comprising:

• acquiring local area information representing a local area that is an area in the original image including the interference fringe image, wherein the local area information represents a position and size of the local area;
• generating a reconstructed image while changing a reconstruction position in the local area;
• calculating sharpness of the reconstructed image each time the reconstructed image is generated by the reconstruction processing to detect an in-focus position where the sharpness is maximized;
• outputting the reconstructed image at the in-focus position as an optimal reconstructed image;
• and
• in a case where the acquired local area information includes a plurality of the local areas, outputting the optimal reconstructed image for each of the local areas, and
• in a case where a plurality of the in-focus positions is detected for one local area, output a plurality of the optimal reconstructed images for the one local area.

A non-transitory storage medium storing an operation program that causes a computer to execute reconstruction processing of an original image including an interference fringe image of at least one object to be observed, the reconstruction processing comprising:

• acquiring local area information representing a local area that is an area in the original image including the interference fringe image, wherein the local area information represents a position and size of the local area;
• generating a reconstructed image while changing a reconstruction position in the local area;
• calculating sharpness of the reconstructed image each time the reconstructed image is generated by the reconstruction processing to detect an in-focus position where the sharpness is maximized;
• outputting the reconstructed image at the in-focus position as an optimal reconstructed image;
• and
• in a case where the acquired local area information includes a plurality of the local areas, outputting the optimal reconstructed image for each of the local areas, and
• in a case where a plurality of the in-focus positions is detected for one local area, output a plurality of the optimal reconstructed images for the one local area.
