In cases when cellular phone 1a plays back a 96x80 pixel video while creating an E-mail with a video attachment or receiving an E-mail with a video attachment, the data communications device enlarges the video periphery and performs playback in 128x96 pixels. Even though the expansion method employed simply enlarges the video periphery, enlarges the scale factor ratio linearly from the center section extending to the periphery and enlarges the scale factor ratio exponentially from the video center section extending to the periphery, a reduction in video visibility by expansion is prevented as the center section is set to 1x (one fold). Consequently, in video playback the common problem of decreased visibility from image deterioration does not occur, resulting in the display area being utilized effectively with enhanced visual effects and image quality. |
