PROBLEM TO BE SOLVED: To allow storing of older image data, without requiring a copying process of image data. SOLUTION: First, a life initial value STAMP [STP_NUM], represented by life number STP_NUM, is set to frame lifetime LIFE[EMPTY] of frame buffer of the number represented by the value of EMPTY (S108). Four kinds of lifetime initial values change as "19→7→11→7", and the value of life number STP_NUM changes between 1 and N_STAMP(=4). When the process S108 is repeated, a life initial value STAMP[1]="19" is set for the frame buffer in which an image is newly stored, if the life number STP_NUM is [1]. Likewise, the life initial value of STAMP [2]="7" is set, if [2]; STAMP[3]="11" is set, if [3]; and STAMP [4]="7" is set, if [4]. COPYRIGHT: (C)2009,JPO&INPIT |
