CURSOR DISPLAY CONTROL SYSTEM OF CARD IMAGE PROCESSING DATA PROCESSOR

摘要

PURPOSE:To perform a correct display of a cursor by converting the relative coordinate value of the cursor on a card image into the absolute coordinate value on a display screen and displaying the real cursor at the position on the screen corresponding to the absolute coordinate value. CONSTITUTION:The coordinate position of a cursor is displayed with correspodence to a card image 1 for each box 2 that corresponds to the image displayed in each frame. This coordinate position is held by the relative coordinate value in the image 1. Then the relative coordinate value of the cursor on the image 1 is converted into the absolute coordinate value on a display screen in correspondence to an actually active frame. The screen is controlled so that the real cursor is displayed at the position on the screen corresponding to the absolute coordinate value. Furthermore the control is given to the relative coordinate value which is changed to the absolute coordinate value in response to the switching of the active frame.
