Patent number: 5453764Abstract: In a video editing apparatus, picture-representing data are stored in an area of a RAM, with a section of the data being selected to be transferred to form a display picture. When a command is supplied for cutting-out a region of the display picture, to replace the cut-out region with other data, the corresponding data region of the RAM area is stored in memory. If the user subsequently designates that the original data of the cut-out region are to be temporarily replaced in the display picture, the position of the cut-out region is calculated with respect to the data region that is currently being selected from the RAM area, the position with respect to the display picture is thereby obtained, and the cut-out data region is then read out of memory and inserted into the display picture at the obtained position.Type: GrantFiled: August 27, 1992Date of Patent: September 26, 1995Assignee: Matsushita Graphic Communication Systems, Inc.Inventor: Tomoki Inagaki
