Abstract

Abstract An image data editing apparatus edits image data coded based on inter-image prediction. Outputted are number data for specifying image data read from a recording medium and edition point data indicative of edition points of the read image data. The image data is read from the recording medium based on the number data. The image data is separated into inter-image prediction method data and prediction residual data. Discontinuity of the image data is discriminated based on the edition point data to change the inter-image prediction extending over before and after the edition points into an inter-image prediction to be conducted within two of the edition points, and outputting changed inter-image prediction method data. The changed inter-image prediction method data and the prediction residual data are multiplexed. An image data decoding apparatus decodes image data coded based on inter-image prediction. The image data is separated into inter-image prediction data indicative of inter-image prediction method, prediction residual data, and edition point data indicative of image data edition timings. The inter-image prediction extending over before and after the edition points is changed into an inter-image prediction to be conducted within two of the edition points according to the edition point data, outputting changed inter-image prediction method data. The image data is predicted based on the changed inter-image prediction data.
