Title:
【発明の名称】画像の境界にまたがる画素値間の相違を減少させるための画像処理回路及び方法
Document Type and Number:
Japanese Patent JP2002531971
Kind Code:
A
Abstract:
An image processing circuit includes a processor that receives at least a portion of an image including a boundary and first and second contiguous pixels disposed on opposite sides of the boundary, the first and second pixels having respective first and second pixel values. The processor generates a boundary value from the first and second pixel values, compares the boundary value to a comparison value, and reduces the difference between the first and second values if the boundary value has a specified relationship to the comparison value. For example, such a processing circuit can be used to reduce blockiness in an image that has undergone block-based digital compression.
