Further, the present invention provides a computer-readable storage medium storing a program for causing a computer to execute each step of the image display method.

In the present invention, the "image of the entire image" refers to an image of the entire image data read from a scanner or a file displayed on a window of a computer screen.

In the present invention, the "enlarged view of the image" means a part of the "entire view of the image" enlarged and displayed on another window of the computer screen.

In the present invention, "decrease in moving speed of the display position of the pointing device" is detected, for example, as follows. That is, when it is detected that the moving speed of the cursor of the pointing device is, for example, less than 10 mm / s in logical coordinates, it is determined that “the moving speed has decreased”. Note that if the moving speed falls to such a range during the general view operation state, the state may immediately transition to the partial enlarged view operation state. However, once it is detected that the cursor moving speed has decreased, The moving speed and acceleration of the pointing device may be halved while the pointing device cursor is positioned within a certain area from the very slow movement start position. After this, or directly without entering the very low-speed movement state, the operation may transit to the partial enlarged view operation state by operating a key on the keyboard or the like. As a result, it may be possible to prevent the operation speed of the pointing device by the operator in the entire image from being amplified and transmitted to the partially enlarged view of the image, thereby preventing the instruction in the partially enlarged view from becoming difficult.

The pointing device used in the present apparatus is optimally a mouse, but may be a tablet.

In the present invention, the transition of the image display state by the instruction input means is performed, for example, as follows. When the pointing device cursor is moved to an enlarged image portion by an instruction of an arbitrary keyboard key instruction input means when the image feature point position is designated, the image portion of the pointing device cursor position in the entire image of the image where the keyboard is designated is enlarged. The display is fixed on the figure, and the pointing device cursor is moved to the position of the enlarged image portion corresponding to the position of the pointing device cursor in the entire image. And again any keyboard
When the key is instructed, the pointing device cursor is moved to the original position in the entire image, and the display of the enlarged partial image following the position of the pointing device cursor is restarted. Instead of the keyboard keys, a pointing device such as a button attached to a mouse may be used as the instruction input means.
