Abstract:
1. A mobile terminal scaling a back image and a front image each with a predetermined scaling factor and overlaying the front image on the back image to display a composite image, the mobile terminal comprising: an input image storage storing input image data of a front image and a back image; an image attribute storage storing a scaling factor, a display image position and a display image size of the front image and the back image; an internal working memory used when performing composition processing of the image data of the front image and the back image stored in the input image storage; an output image storage storing processed image data; a processing unit block calculator dynamically determining a processing unit block according to capacity of the internal working memory, the scaling factor, the display image position and the display image size of the front image and the back image stored in the image attribute storage, and an amount of processed image data updated dynamically each time composition processing in each processing unit block ends; and an image processor producing composite image data by repeating dynamically obtaining the processing unit block determined by the processing unit block calculator, partially obtaining data from the image data of the front image and the back image stored in the input image storage based on the processing unit block, the scaling factor, the display image position and the display image size of the front image and the back image stored in the image attribute storage, and the amount of processed image data updated dynamically each time composition processing in each processing unit block ends, generating partial composite image data by composition processing within the processing unit block using the internal working memory, and outputting the data to the output image storage.
