摘要： A reference block is divided in the horizontal direction into small blocks, and is also divided in the vertical direction into small blocks. Feature values representing each of the small blocks formed from the reference block are obtained. Similarly, a check block is divided in the horizontal and vertical directions into small blocks and feature values representing the small blocks formed from the check block are obtained. The feature values in the horizontal direction of the reference and check blocks are compared, and the feature values in the vertical direction of the reference and check blocks are compared. The results of the two comparisons comprise an evaluation value by which the degree of matching of the reference and check blocks is evaluated. The check block is moved throughout a predetermined search range, and the process is repeated for each position of the check block. A motion vector is produced between the reference block and the check block position at which the check block best matches the reference block.

摘要： In step S1, the capacity of the area (remaining quantity) of a disk in which information can be recorded is read, and the remaining quantity is displayed in step S2. After a user inputs the recording time of information to be recorded and the recording capacity w for the recording, an average transmission rate R.sub.1 is calculated from expression R.sub.1 =w/t-.alpha. in step S4. The rate .alpha. is the transmission rate for transmitting signals other than a video signal, such as an audio signal, attached to the video signal. Data obtained by applying a DCT treatment to the video data is quantized with a quantization width corresponding to the average transmission rate R.sub.1 and this data is intermittently recorded on the disk.
