File execution method and system for a portable device

Abstract

A file execution method and system for a portable device for expediting an execution of files is provided. A method for executing an audio file including at least one track associated with a cover image includes displaying a first cover image associated with a track that is playing and displaying a first track list on the first cover image in response to a first key input signal, the first track list listing tracks associated with the first cover image. The portable device implemented with the file execution method and system of the present invention enables a track list to be displayed together with a cover image shared by a set of tracks listed on the track list, thereby expediting execution of files.

What is claimed is: 
     
         1 . A method for executing an audio file including at least one track associated with a cover image, comprising:
 displaying a first cover image associated with a track that is playing; and   displaying a first track list on the first cover image in response to a first key input signal, the first track list listing tracks associated with the first cover image.   
     
     
         2 . The method of  claim 1 , wherein the displaying of the first track list comprises:
 displaying the first cover image on a bottom layer; and   displaying the first track list on a top layer.   
     
     
         3 . The method of  claim 2 , wherein the first cover image is displayed more dimly than the first track list. 
     
     
         4 . The method of  claim 3 , wherein the first cover is displayed at one or more of a low saturation level, a low brightness level and a low resolution level, in comparison with the first track list. 
     
     
         5 . The method of  claim 1 , further comprising:
 selecting a track from the first track list displayed on the first cover image; and   displaying track information of the selected track on the first cover image.   
     
     
         6 . The method of  claim 5 , wherein the displaying of the track information comprises:
 displaying the first cover image on a bottom layer; and   displaying the track information on a top layer which comprises a smaller size than the bottom layer.   
     
     
         7 . The method of  claim 6 , wherein a portion of the first cover image that is overlapped with the track information is displayed more dimly than a portion of the first cover image that is not overlapped with the track information. 
     
     
         8 . The method of  claim 6 , wherein the first cover image is displayed at one or more of a saturation level, brightness level and resolution level that is identical with that of the track information. 
     
     
         9 . The method of  claim 6 , wherein the displaying of the track information discontinues after a preset time period. 
     
     
         10 . The method of  claim 1 , further comprising receiving a second key input signal and displaying a second track list on a second cover image in response to the second key input signal. 
     
     
         11 . The method of  claim 10 , wherein the second track list is displayed more clearly than the second cover image. 
     
     
         12 . The method of  claim 11 , wherein the displaying of the second track list on the second cover image comprises:
 displaying the second track list on a top layer; and   displaying the second cover image on a bottom layer disposed below the top layer, the second track list being displayed at one or more of a high saturation level, a high brightness level and a high resolution level, in comparison with the second cover image.   
     
     
         13 . The method of  claim 10 , further comprising:
 selecting a track from the second track list; and   displaying track information of the selected track on the second cover image.   
     
     
         14 . The method of  claim 13 , wherein the track information is displayed on a portion of the second cover image, and the portion of the second cover image, on which the track information is displayed, is displayed at one or more of a low saturation level, a low brightness level and a low resolution level. 
     
     
         15 . The method of  claim 13 , wherein the displaying of the track information discontinues after at least one of a discontinuation of a playing of the track and a preset time period from the initiation of the playing of the track. 
     
     
         16 . The method of  claim 15 , wherein the displaying of the second cover image is restored to one or more of a normal saturation level, a normal brightness level and a normal resolution level on the portion on which the track information is displayed, after the displaying of the track information has discontinued. 
     
     
         17 . A portable device displaying a cover image associated with a track, comprising:
 a display unit for displaying a cover image;   an audio processing unit for playing a track associated with the cover image;   a memory unit for storing the cover image and the track; and   a control unit for controlling the display unit to display the cover image and to display a first track list on the cover image in response to a first input signal, the track list listing tracks associated with the cover image.   
     
     
         18 . The portable device of  claim 17 , wherein the control unit controls the display unit to display a second cover image and display a second track list on the second cover image in response to a second input signal. 
     
     
         19 . The portable device of  claim 18 , wherein the control unit detects a selection to a track from one of the first and second track lists and controls the display unit to display track information with a cover image corresponding to the selected track. 
     
     
         20 . The portable device of  claim 19 , wherein the control unit controls the display of the track information to be discontinued after a preset time has elapsed from a start of a playback of the selected track.
