Abstract
Official abstract text for this publication.
An image data encoding apparatus and method and an image data decoding apparatus and method are provided. The image data encoding apparatus may perform at least one image prediction with respect to image data, and select a prediction mode for encoding. The image data encoding apparatus may simultaneously perform both intra prediction and color prediction, and thereby may efficiently perform encoding.
First claim
Opening claim text (preview).
What is claimed is: 1. An image data encoding apparatus, comprising: an image prediction unit comprising; a first prediction unit to perform intra prediction based on a spatial correlation of image data that is divided by a coding unit; a second prediction unit to perform color prediction based on a color correlation of the image data where the intra prediction is performed; and a mode selection unit to select a prediction mode for at least one coding unit based on a result o…
