Title:
IMAGE ENCODING DEVICE, IMAGE ENCODING METHOD, IMAGE ENCODING PROGRAM, IMAGE DECODING DEVICE, IMAGE DECODING METHOD, AND IMAGE DECODING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/108634
Kind Code:
A1
Abstract:
An image encoding device for encoding an image signal containing a brightness signal and a color-difference signal in block units, wherein an orthogonal transform/quantization unit (107) respectively sets an encoding block of the brightness signal and an encoding block of the color-difference signal as one or more transform blocks having a prescribed shape, and orthogonally transforms the transform blocks of the brightness signal and the transform blocks of the color-difference signal. A third encoding-bit-stream generation unit (114) encodes the orthogonally transformed transform blocks of the brightness and color-difference signals, and generates an encoding bit stream.
