In this paper, an inter-frame adaptive prediction encoding system was proposed to prevent the deterioration of picture quality without deteriorating prediction efficiency even if movement changes and the correlation of interframe changes and which can reduce an operation amount required for prediction.
Abstract
PURPOSE: To supply an inter-frame adaptive prediction encoding system which can prevent the deterioration of picture quality without deteriorating prediction efficiency even if movement changes and the correlation of inter-frame changes and which can reduce an operation amount required for prediction. CONSTITUTION: An encoding part 3 encodes a key frame at a prescribed interval as against a picture signal 1 which is continuously inputted, and a predictor 17 predicts an interpolation frame between the previously encoded key frames by using a preceding frame by two, the preceding frame and subsequent frame.
