PURPOSE:To display surely a required image even if how to display is not set by providing a displaying means dividing a displaying region into displaying regions for a component image and a synthetic image and control means displaying the component image on a synthetic image displaying region and forming thereby a multi-screen dividing and displaying means. CONSTITUTION:When an image display dividing a work region is started, a CPU checks if an image data exists in a No.1 storing part R1 (for an image of a component R) of a fixed magnetic disc and if it exists, a reduced image data of the image data is transferred to a memory part F1 of an plane-R 19R of a frame memory 19 and it is also transferred to a memory part F4. Then, a reduced image data of a No.1 storing part G1 is transferred to a memory part F2 of a plane-G 19G of the frame memory 19 and it is transferred to the memory part F4. Then, a reduced image data of an image data of a No.1 storing part B1 is transferred to a memory part F3 of a plane-B 19B of the frame memory 19 and it is transferred to the memory part F4 and the procedure is shifted to the next process. Data which have been completely transferred to the frame memory 19 are displayed thus on a monitor 20 and the component image and the synthetic image are displayed as a pair. |
