Title:
動き情報処理装置及び方法
Document Type and Number:
Japanese Patent JP4217543
Kind Code:
B2
Abstract:
A method for processing motion information in an input interlace-scanned pixel signal is disclosed. The motion information processing method includes the steps of detecting motion information of a target pixel based on difference information of a pixel signal at the same location between two fields, outputting the motion information of the target pixel by determining the motion information of the target pixel based on the detected motion information of the target pixel in the target field and the motion information of the target pixel in a past field prior to the target field, and determining whether moving pixels of at least a predetermined number are present within an area containing a plurality of adjacent pixels containing the target pixel in the target field, wherein the moving pixel has motion information indicating a moving picture. The motion information of the target pixel is determined in the outputting step with the motion information of the target pixel in the past field disregarded if the number of the moving pixels is not larger than the predetermined number.
