IMAGE CONVERSION DEVICE AND IMAGE CONVERSION METHOD

摘要

According to an interlace video signal which has been input, a plurality of interlace video signals corresponding to a plurality of continuous fields are generated by a first, a second, and a third one-field delay circuit. According to a plurality of interlace video signals, a first progressive video field signal is generated by a first progressive video generation circuit. According to a plurality of interlace video signals, a second progressive video field signal is generated by a second progressive video generation circuit. According to the first progressive video field signal and the second progressive video field signal, image vertical-direction motion amount information is calculated by a comparison circuit.
