Abstract
In cases when cellular phone 1a plays back a 96×80 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 128×96 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 1× (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.

2. A cellular phone with a digital camera comprising:
-
a shutter key; a still picture image pick-up means for recording still pictures when said shutter key is operated less than predetermined time; a video image pick-up means for recording video when said shutter key is operated more than predetermined time; a storage means for storing said recorded still pictures or video; an E-mail transceiver means for transmitting said still pictures or video stored in said storage means by E-mail attachment, and for receiving still pictures or video by E-mail attachment; a still picture display means for displaying still pictures stored in said storage means; and a video display means for displaying video stored in said storage means, wherein said video display means enlarges a periphery of video by a different ratio from a center section and performs video playback in a display size of a still picture.

3. The data communications device comprising:
-
a receiving means for receiving still pictures and video; an image pick-up means for recording still pictures and video; a storage means for storing said still pictures and video recorded by said image pick-up means, or said still pictures or video received by said receiving means; a display means for displaying still pictures or video stored in said storage means; a video playback means for selecting video stored in said storage means, for enlarging a video periphery of said selected video and for performing continuous playback in a display size of said still picture; a pause direction means for directing to suspend playback of the video; and a display control means for controlling said display means to suspend playback of the video, to enlarge a still picture at that instant uniformly, and to display on said display means when there are pause directions from said pause direction means.
