A moving picture data editing device comprising: a command input unit that accepts an operation command entered by a user; a storage unit that stores moving picture data; a decoding means for decoding the moving picture data read from the storage unit into display image data; a thumbnail generating means for generating a thumbnail of a portion, appearing at every predetermined time, of an image formed from the moving picture data; a display image generation and output unit operable to: output the display image data from the decoding means to a display unit, and reproduce the image on the display unit so that the moving picture data is replayed to the user; generate image data so that a central thumbnail of the reproduced image being displayed on a screen of the display unit and a plurality of initial thumbnails of images earlier than the reproduced image are displayed superposed on the reproduced image when a first predetermined operation is made of the command input unit; and output the image data to the display unit; wherein the central thumbnail of the reproduced image being displayed on the screen is displayed in a horizontally central area of the screen, wherein the plurality of initial thumbnails of the images earlier than the reproduced image are displayed in a left area of the screen to the left of the central area, wherein the central thumbnail in the central area is displayed to be emphasized compared to the plurality of initial thumbnails in the left area, wherein the display image generation and output unit is operable to additionally display a plurality of additional thumbnails in a right area of the screen to the right of the central area after a command for a pause operation is entered to the command input unit, the plurality of additional thumbnails being for images later than the reproduced image being displayed, when a second predetermined operation is made of the command input unit to enter the command for a pause operation while the central thumbnail of the reproduced image is being displayed in the central area of the screen and the plurality of initial thumbnails of the images earlier than the reproduced image are being displayed in the left area of the screen, further comprising a means for adding, to the moving picture data, information on edit points indicating image data positions corresponding to one, designated by the command input unit, of the central thumbnail and the plurality of initial and additional thumbnails displayed on the screen of the display unit, and storing the data into the storage unit. a command input unit that accepts an operation command entered by a user;
