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

A digital versatile disc (DVD) player capable of dynamically displaying digital images by coordinate conversion on a virtual plane, comprising:

• an image output interface connected to a display unit;
• a storage unit storing at least a digital image;
• and
• a processing unit, wherein the processing unit establishes a virtual plane comprising a display region in the center, the display region and the digital image are of the same dimension, and the processing unit projects the digital image in the storage unit on the virtual plane to form an image region, decides a moving trace of the image region on the virtual plane, determines whether the image region and the display region overlap, and, if so, outputs a corresponding part of the digital image to the image output interface.

A digital still camera (DSC) capable of dynamically displaying digital images by coordinate conversion on a virtual plane, comprising:

• a display unit comprising a screen;
• an image capture unit generating at least a digital image by capturing an external image;
• a storage unit storing the digital image;
• and
• a processing unit, wherein the processing unit establishes a virtual plane comprising a display region in the center, the display region corresponds to the screen of the display unit in a one-to-one pixel style, the display region and the digital image are of the same dimension, and the processing unit projects the digital image in the storage unit on the virtual plane to form an image region, decides a moving trace of the image region on the virtual plane, determines whether the image region and the display region overlap, and, if so, displays a corresponding part of the digital image on a corresponding part of the screen.
