Method and device for dynamically displaying image by virtual plane coordinate conversion

摘要

Device and method capable of dynamically displaying digital images by coordinate conversion on a virtual plane are provided. The device includes a display unit, a storage unit, and a processing unit. The display unit includes a screen. The storage unit stores a digital image. The processing unit establishes a virtual plane including a display region corresponding to the screen of the display unit, projects the digital image on the virtual plane to form an image region, and decides a moving trace of the image region on the virtual plane. When the image region and the display region overlap, the processing unit calculates the overlap and displays a corresponding part of the digital image by reading from the storage unit on a corresponding part of the screen.
