PROBLEM TO BE SOLVED: To instantly obtain both information of picture and relative size on pictures having various sizes by determining a reduction factor with respect to original picture data having different sizes based on a difference between the maximum size and the minimum size and relatively grasping the picture size of a reduced image in addition to its pattern. SOLUTION: First, the original picture data is retrieved, and a figure (a) being the minimum original data and a figure (b) being the maximum original data are extracted therefrom. These extracted minimum original picture data figure (a) and maximum original picture data figure (b) are compared, and its size differs in twice or more than twice, it is decided that the original picture data are compressed by a prescribed logarithm factor. Then, all the original picture data retrieved at first is reductively displayed in accordance with the logarithm factor or a compression factor determined by a one-dimensional factor, and as a result, figures a' to d' are obtained. Then, in the case where the difference of the size between the maximum picture data and the minimum picture data is equal to below twice, its magnification can be set unlimitedly. |
