Title:
LCDパネルにおける画像表示に適したDWTに基づくアップサンプリング・アルゴリズム
Document Type and Number:
Japanese Patent JP4465112
Kind Code:
B2
Abstract:
A method comprising constructing virtual (Discrete Wavelet Transform) DWT sub-bands; from an image without performing the DWT and then applying an inverse DWT upon the virtual sub-bands, the result of the inverse DWT representing an up-sampled version of the image. Alternatively, an apparatus comprising an interface configured to communicate image data, and an up-sampling unit, the up-sampling unit coupled to the interface to receive the image data, the up-sampling unit configured to construct virtual sub-band input data from the image data, the up-sampling unit configured to perform an inverse DWT upon the input data generating an up-sampled image therefrom. In an alternate embodiment, an apparatus comprising a computer readable medium having instructions which when executed perform constructing virtual (Discrete Wavelet Transform) DWT sub-bands from an image without performing the DWT, applying an inverse DWT upon the virtual sub-bands, the result of the inverse DWT representing an up-sampled version of the image.
