Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2012/008389
Kind Code:
A1
Abstract:
Disclosed are an image processing device, image processing method, and program that can reduce the amount of processing required for a ROT and a DCT or an inverse DCT and an inverse ROT. By inverse-quantizing image information obtained by decoding an encoded image, low-frequency components of said image information, obtained via a first orthogonal transformation unit, and high-frequency components of said image information, obtained via a second orthogonal transformation unit, are obtained. Said high-frequency components are higher in frequency than said low-frequency components. Said low-frequency components and high-frequency components are then subjected to an inverse orthogonal transformation via a similar technique. This technology can be applied, for example, to image encoding and decoding.
