ABSTRACT:
An information processing apparatus uses an information memory for storing image information and first and second controllers for controlling the storage of image information associated with a generated graphics event into the memory based on a display request from a pointing device. In addition, image information for one frame of the display is stored into the image information memory by a first storer, and image information for a window display is stored into the image information memory by a second storer. An image transfer controller controls an image transfer from the image information memory such that when, during storing of the image information for one frame of the display, without the display request for the window display, the display request from the pointing device is generated, and the first controller controls the start of storage of image information when, during storing of the image information by the first storer, the display request of the window display and the display request from the pointing device are produced, the display request of the window display is met by the second storer for storing image information for the window display, and the display request from the pointing device is met by the second controller. A matrix electrode with scanning lines and information lines can also be provided, along with a driver for driving the matrix electrode.
