Interactive image display method and interactive device

An interactive image display method to be performed by an interactive device that includes an input module, a memory module, a processing module and a display module, the memory module storing an overlaying graphic image and a background graphic image, said interactive image display method comprising steps of:

• (a) rendering, using the processing module, a first interactive image that has the background graphic image overlaid with the overlaying graphic image in a manner that the background graphic image is hidden from view by the overlaying graphic image when the first interactive image is displayed on a screen of the display module;
• (b) generating, using the input module, a triggering instruction in response to user operation;
• (c) in response to receipt of the triggering instruction from the input module, rendering, using the processing module, a second interactive image in which a portion of the background graphic image hidden from view by the overlaying graphic image in the first interactive image is revealed when the second interactive image is displayed on the screen of the display module;
• and
• (d) after a predetermined time has elapsed subsequent to receipt of the triggering instruction, rendering, using the processing module, a third interactive image that has the background graphic image overlaid with the overlaying graphic image in a manner that the background graphic image is hidden from view by the overlaying graphic image when the third interactive image is displayed on the screen of the display module.
