A screen editor and screen editing method for extracting part of one screen to insert it into another screen includes first and second memories for storing input screen data, an output selection switch for transmitting either of the screen data read out from the first or second memories, a coordinates designator for designating an extracted region of the second memory and an inserting reference point of the first memory, a controller for calculating editing data containing the addresses of the inserting reference point, extracting reference point and region increments, and controlling the memories and coordinates designator, and an address generator for generating the read addresses of the first and second memories and controlling the output selection switch.
