Abstract
An encoding preprocessing partextracts the amount of image feature relative to image data and passes the amount of image feature to a control partas image feature amount informationand also sends image datato an encoding partThe control partdetermines whether there is a dissolve image or not based on the image feature amount informationand if it is determined that the image datais the dissolve image, an encoding parameteris set so that a configuration of GOP which is normally M=3 is changed into the configuration of GOP of M=2, and the encoding partperforms encoding based on the encoding parameterAs a result of that, a prediction error of a B-picture frame in a dissolve interval becomes substantially zero and on encoding in the dissolve interval, the amount of information occurrence in frames except I-picture and P-picture frames can be reduced and thus the amount of information occurrence as a whole can be reduced.
