Image processing device and image processing method for encoding a block of an image

摘要

Provided is an image processing apparatus including a prediction section that generates a predicted value of a color difference component of a pixel of an image to be decoded by using a function of a value of a corresponding luminance component, a coefficient calculation section that calculates a coefficient of the function used by the prediction section by referencing a pixel around a block to which the pixel belongs, and a controller that controls a ratio of a number of reference pixels used by the coefficient calculation section to a block size of the block.

主权项

1. An image processing device comprising:
an assigning unit configured to assign an encoding order for a current coding block including first block, second block, third block, and fourth block to the current coding block as a first luma block in the first block, a first chroma block in the first block, a second luma block in the second block, a second chroma block in the second block, a third luma block in the third block, a third chroma block in the third block, a fourth luma block in the fourth block, a fourth chroma block in the fourth block; and an encoding unit configured to encode the current block according to the assigned encoding order, wherein the assigning unit and the encoding unit are each implemented via at least one processor.
