Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a display device that displays a plurality of windows.

(Prior art) When a specific part of an original image is enlarged and displayed, the enlarged display part becomes easier to see and operate, but as the enlargement ratio increases, it becomes difficult to understand which part of the entire original image the enlarged display part is. It becomes difficult to understand. For this reason, conventionally, it has been done to display which part of the original image is being enlarged (for example, ``Image display method'' in Japanese Patent Application Laid-Open No. 61-248185, ``Image Display Method'' in Japanese Patent Application Laid-Open No. 82-143093, (See “Works Scene”). However, in such conventional techniques, the enlarged display portion cannot be moved, and it takes time and effort to set the position of the enlarged display portion. Another problem is that although the enlarged image is displayed over the entire screen, the original image itself is displayed small.

In addition, some existing software can be displayed in multiple windows by dividing the window screen, but in this case, it is not possible to specify any part of the original image to partially display, and the display I couldn't change the magnification either.

(Problems to be Solved by the Invention) The present invention is capable of displaying and enlarging a specified partial area in one window in another window (partial display window) in a display device that displays multiple windows. It is an object of the present invention to provide a display device that can control changes to the partial area in the partial display window after opening the partial display window.

(Means for Solving the Problems) The present invention provides an apparatus for displaying a plurality of windows on a display screen, etc., by specifying a partial display area of an image in a certain window (full display window). This display device displays an image in another window (partial display window) and is provided with partial display control means for controlling scrolling of the display portion, change of display magnification, and display range within the partial display window.

(Operation) A part of the image data is extracted from the original image and displayed in another window (partial display window).

At this time, by performing a scroll operation from this partial display window, the portion (partial display area) on the original image that is being partially displayed can be moved, and the displayed content can be changed. This partial display area is displayed as a frame or the like on the original image, and its position in the entire image can be easily identified. Also, if you change the display magnification of the partial display window or change the size of the partial display window, the shape of the partial display area on this original image will change to correspond to the display image of that partial display window. .
