PROBLEM TO BE SOLVED: To display an image of an image data file onto a screen with a proper aspect ratio by converting number of picture element samples of the image data file in the case that an aspect ratio of an occupied area of a unit picture element sample differs from a display screen of a computer system and from image data of an image data file. SOLUTION: A decode block 21 applies decode processing to received image file data in the unit of a digital interface blocks and converts the data into sample data of a luminance signal component and a color difference signal component and provides an output of the result with a normal/wide identification signal of an image file to be displayed. A picture element number conversion block 22 converts, e.g. number of picture elements in the horizontal direction based on the received component signal data by one frame, an NTSC/PAL identification signal and the normal/wide identification signal. Thus, the image file is displayed with a proper aspect ratio even on a display screen of a monitor of a computer. |
