SIGNAL PROCESSING METHOD AND SIGNAL PROCESSING DEVICE

Title:

SIGNAL PROCESSING METHOD AND SIGNAL PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/043009

Kind Code:

A1

Abstract:

This signal processing method, which is executed using a computer, includes: acquiring a compressed image that includes compressed information pertaining to a subject; acquiring a first parameter group and a restoration matrix that are used in a first restoration process for generating a restoration target image from the compressed image; generating the restoration target image on the basis of the compressed image, the first parameter group, and the restoration matrix; acquiring a second parameter group that is used in a second restoration process for generating a restored image from the compressed image; generating the restored image on the basis of the compressed image, the second parameter group, and the restoration matrix; and correcting the second parameter group on the basis of the restoration target image and the restored image.
