2. Description of the Related Art In recent years, various information processing apparatuses such as a desktop publishing (DTP) and a filling system have undergone remarkable technological development, and accordingly, various editing functions have been required and high operability has been required. There is a need for a device.

In particular, when creating a character pattern or editing an enlarged image, that is, when editing a dot on the display screen, it is necessary to perform an operation of moving the cursor in units of dots, and the user must pay close attention to the operation. Can be forced.

For example, in a so-called dot-editing operation of designating a desired dot on a display screen or designating an area surrounding the desired dot, the pointing device cursor is moved to move the editing object. It is necessary to specify a target dot or an area surrounding the target dot.

However, the movement of the pointing device / cursor is all-round and is not suitable for a detailed position designation operation. Therefore, a dot at a position next to a desired dot is designated, and the movement of the pointing device / cursor is larger than a desired area. In practice, the case of occupying a small area often occurs.

For this reason, the user needs to perform the editing operation on the dot target with a great deal of tension compared to the normal operation and must perform the operation with caution, and the operation efficiency is significantly reduced. Was.
