To display an image based on image file data generated from moving images, the number of pixels is changed in the horizontal or vertical direction of a display screen by a signal processing operation. Various television broadcast standards and display modes are supported. For example, in the NTSC system, a signal processing operation subjects frame data (720 by 480 pixels) to 8:9 pixel count conversion for converting the number of pixels in the horizontal direction from 720 to 640. An image based on the image file data (i.e., still picture) is therefore displayed on the computer screen with the correct aspect ratio. |

DETAILED DESCRIPTION These and other objects, features and advantages are accomplished by an apparatus and method for displaying an image based on coded digital moving image data.
In accordance with the present invention, image data, represented by frame data, is extracted from the coded digital moving image data.
The extracted image data, defined by a predetermined number of pixels, is then decoded.
Thereafter, the decoded image data is converted by selectively changing the predetermined number of pixels in a horizontal or vertical direction of the image.
As a result, the image represented by the converted image data is displayed with a correct aspect ratio.
In accordance with one aspect of the present invention, a television system format corresponding to the image data is determined.
Consequently, the predetermined number of pixels is changed on the basis of the television system format.
In accordance with another aspect of the present invention, a display mode corresponding to the image data is determined.
The predetermined number of pixels is changed on the basis of the display mode.
