Title:
IMAGE RECORDING DEVICE AND IMAGE REPRODUCING DEVICE, AND METHOD AND PROGRAM FOR SAME
Document Type and Number:
WIPO Patent Application WO/2016/158466
Kind Code:
A1
Abstract:
Provided are an image recording device, an image recording method, an image reproducing device, an image reproducing method, and programs for the same, with which redundancy in recorded data is eliminated. First sampling data are obtained by sampling original image data. The first sampling data and the original image data are divided into a plurality of blocks and are each subjected to an orthogonal transformation, yielding first frequency component data and second frequency component data. Difference data between the first frequency component data and the second frequency component data, and the first frequency component data, are recorded. The difference data and the first frequency component data are not duplicated, and redundancy is eliminated therefrom. Images are reproduced rapidly by reproducing only the first frequency component data, and images having a high image quality are reproduced by reproducing the first frequency component data and the difference data.
