发明名称 Image display apparatus and method having virtual cursor
摘要 Image display equipment has a memory element for storing a selected combinatorial function of a cursor pattern and image field existing at an addressed cursor position, and has a controllable selector for displaying, at the cursor field, either the image field or the combined cursor field and image pattern. A single display memory can store the image field, the cursor pattern, and the selected combination of cursor pattern and image field. Selection logic addresses the stored combination pattern in lieu of the image field to provide the desired cursor display at the addressed cursor position.
