Abstract
A positioning apparatus capable of making a position of a pointer on a screen stand out and be prominent at appropriate timing for the user when the user uses a pointing device, such as a mouse. A color of an image within a first region on a screen and a color of an image within a second region, a size of which differs from the size of the first region, are alternately displayed by inverting the image data of the image within the region around a mouse cursor, during the simultaneous depression of a right button of the mouse and a shift key of a keyboard by the user. The use of a rectangular area as the first region in which the center of the area aligns to the coordinate values (MX, MY) of the mouse cursor, and the coordinate values of a top right corner are represented by (MX+L1,MY+L1) and the coordinate values of a bottom left corner are represented by (MX−L1MY−L1), and a rectangular area as the second region in which the center of the area aligns to the coordinate values (MX,MY) of the mouse cursor, and the coordinate values of the top right corner are represented by (MX+L2,MY+L2) and the coordinate values of a bottom left corner are represented by (MX−L2,MY…
