BIDIRECTIONAL DISPLAY METHOD AND BIDIRECTIONAL DISPLAY DEVICE

摘要

A bidirectional display method includes: having an image signal inputted from an external device; displaying an image on an image screen on the basis of a display signal; detecting an operation to the image screen; drawing an operation input object corresponding to the operation to the image screen; outputting the display signal for displaying a combined image formed by combining an external image based on the image signal and the operation input object; detecting a change in an attribute of the image signal or in the image signal; and link-editing the operation input object so as to correspond to a change in the external image when a change in the attribute of the image signal or in the image signal is detected.
