ABSTRACT:
An image data processing apparatus obtains a first absolute address of a frame by reading marks which are provided on a recording medium for the purpose of setting absolute addresses. Divisions which separate the frames on the recording medium into blocks are input, together with the relative addresses of the frames within the divisions. The apparatus stores frame data in such a manner that the divisions, the relative addresses of the frames of each of the divisions, and the absolute addresses of the frames are arranged so as to correspond to each other. The apparatus obtains a second absolute address of a frame to be processed which address corresponds to the input division and the input relative address of the frame within the division. An amount of feed of the recording medium which is needed to move the frame to be processed to the processing position is calculated from the difference between the first and second absolute addresses, and the frame to be processed is moved to the processing position in accordance with the calculated amount of feed. Thus, the image of the frame present at the processing position is processed. Accordingly, frame images can be readily put in order, and retrieval thereof is facilitated.
