Patent ID: 7729425

Claim:
An image processing apparatus for performing at least part of coding processing on image data, comprising: data conversion means for performing at least part of the coding processing on the image data; detection means for detecting an editing point of the image data, the editing point detected based on at least one factor indicating discontinuity between frames of the image data, wherein the at least one factor includes additional coding information added to the image data; and control means for determining, based on the editing point detected by the detection means, a reuse disable period in which information concerning previous coding processing performed on the image data is not reusable when the data conversion means performs at least part of the coding processing, wherein the control means: detects first image data corresponding to a P picture which is positioned temporally after the frame at the editing point detected by the detection means for a predetermined number of frames, and detects second image data corresponding to a frame which is positioned temporally after the first image data by a predetermined number of frames, and controls third image data corresponding to a frame one frame before an I picture positioned after and closest to the frame corresponding to the second image data to be an end position of the reuse disable period.
