摘要

In order to display an image based on image file data, such as that stored on a recording medium (6), originally generated from moving images for example from a VTR (1), the number of pixels is changed in the horizontal or vertical direction of a display screen by a signal processing operation in a controller (4). 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) may therefore be displayed on the computer screen (9) with the correct aspect ratio.
