Decoding method, decoding apparatus, storage medium in which decoding program is stored, and electronic camera

摘要

In a decoding method for decoding coded light ray information, coded first image information and coded second image information different from the first image information are decoded. The first image information and the second image information are obtained in taking a subject. The light ray information is generated based on the decoded first and second image information. Image information corresponding to a first focus value is generated and stored in a storage medium, based on the generated light ray information. An image is displayed based on the image information corresponding to the first focus value. Image information corresponding to a second focus value different from the first focus value is generated and stored in the storage medium, based on the generated light ray information. The image information corresponding to the second focus value is generated and stored, while the image is displayed or before the image is displayed.
