COMPUTING APPARATUS FOR CONVERTING IMAGE AND METHOD FOR OPERATING SAME

Title:

COMPUTING APPARATUS FOR CONVERTING IMAGE AND METHOD FOR OPERATING SAME

Document Type and Number:

WIPO Patent Application WO/2021/029719

Kind Code:

A1

Abstract:

A method for converting an image by using a computing apparatus is disclosed. The method comprises the steps of: acquiring a first standard red-green-blue (sRGB) image having an sRGB color gamut for a content; acquiring a first converted image obtained by converting the color gamut of the first sRGB image into a color gamut of a digital cinema initiative-P3 (DCI-P3) by using a neural network; and on the basis of a second converted image, generated by applying a first color conversion matrix to the first sRGB image, and the first converted image, generating a final converted image obtained by converting the color gamut of the first sRGB image into the DCI-P3 color gamut.
