Title:
【発明の名称】オフセットサブサンプリングデコード装置
Document Type and Number:
Japanese Patent JP3285892
Kind Code:
B2
Abstract:
PURPOSE:To process the signal, which is subjected to offset sampling, in accordance with the motion of a frame unit and a field unit. CONSTITUTION:This decoder is provided with a partial detection circuit 101 which detects the extent of motion of a high definition television signal subjected to offset sampling to obtain a motion detection signal, an inter-frame interpolation circuit 102 which obtains an inter-frame motion detection signal by inter- frame interpolation of the motion detection signal, a switching circuit 106 which switches the outputs of a inter-frame interpolation circuit 104 and an intra-field interpolation circuit 105 based on the inter-frame motion detection signal, a field delay circuit 103 which delays the inter-frame motion detection signal by one field to obtain an inter-field motion detection signal, and a switching circuit 109 which switches the outputs of the inter-field interpolation circuit 107 and the intra-field interpolation circuit 108 based on the inter-field interpolation circuit 108 based on the inter-field motion detection signal.
