Vorrichtung zur Codierung und Decodierung eines digitalen Bildsignales |
摘要 |
<p>A coding device of a digital image signal coding highly efficiently a digital image signal by using a bidirectional motion compensating prediction and a DCT (digital cosine transform) transformation thereby compressing information, including means for inputting reference images for coding images for a bidirectional prediction to a spatial region as data and blocking the data, means for coding the blocked data, means for writing the coded data to a memory, means for reading reference regions for calculating a motion vector for prediction or data of the reference regions for calculating a prediction value from the memory, means for decoding the read data, and means for calculating the motion vector or means for calculating the prediction value by using the decoded data. <IMAGE></p> |
