<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus which can learn a graph shape represented by an object, an event or the like in an image, in association with a graph expression expressed by real size of the graph shape. <P>SOLUTION: A scientific calculator 1 comprises: a display 3 for displaying an image; a CPU 11 for detecting a graph figure corresponding to a predetermined graph shape in the image to draw a graph on the graph figure in a superposed manner; and an input unit 14 for specifying an optional line segment in the image as a line segment of a length input target and also inputting length of the line segment of the length input target. The CPU 11 sets origin coordinates in the image according to a position and a shape of the graph, and calculates a display coordinate range which is to be set on the image based on the length of the line segment of the length input target. Also, the CPU 11 calculates a graph expression of the graph based on the display range to display the graph expression on the display 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
