Patent ID: 8379065

Claim:
A mobile communication terminal configured to display a high resolution picture, comprising: a wireless transmitting/receiving unit configured to receive high resolution picture data through a mobile communication network; a memory; a format converting unit configured to convert the high resolution picture data from the wireless transmitting/receiving unit into picture file formatted data including a plurality of unit blocks of high resolution picture data and indexes for providing access to each block of high resolution picture data, and configured to store the picture file formatted data in the memory, the format converting unit including: a picture dividing unit configured to divide the high resolution picture data into the plurality of unit blocks of high resolution picture data; and a storing unit configured to generate the indexes for each of the divided unit blocks of the high resolution picture data and to store the file formatted picture including the index information and each unit block of the high resolution picture data based on the index information in the memory; a picture data processing unit configured to select, and extract a minimum number of unit blocks using the index information of the picture file formatted data and output a high resolution partial picture of only a portion of the high resolution picture based upon the selected and extracted minimum number of unit blocks, the picture data processing unit including: a decoding block selecting unit; and a decoding frame generating unit; and a display unit configured to display the partial picture, wherein a scroll action operates to change a position of the partial picture within the high resolution picture by selecting and extracting only those unit blocks which need to be additionally decoded; wherein the size of each unit block of picture data is less than a size of the partial picture; and wherein the partial picture has the same resolution as the high resolution picture.
