ABSTRACT:
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 inputting reference images for coding images for a bidirectional prediction to a spatial region as data and blocking the data, coding the blocked data, writing the coded data to a memory, reading reference regions for calculating a motion vector for prediction or data of the reference regions for calculating a prediction value from the memory, decoding the read data, and calculating the motion vector or means for calculating the prediction value by using the decoded data.
