Filed: 2002-10-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a display controller which can give image data with which directions of images become identical at high speed and stably even when the display screen of the device is in either a vertically long state or a horizontally long state.  <P>SOLUTION: Image data are divided into memory-width data and the memory-width data are written in a data frame memory 11 by specifying addresses.

Moreover, vertical and horizontal converted image data can be prepared by converting the arrangement position of the pixel data in a pixel data group according to the predetermined rule. In writing the image data in the frame memory 11, since the image data are converted in the memory-width data, the data can be efficiently stored in the memory 11 with respect to a limited memory capacity. Furthermore, since a display controller can be realized by hardware, the arrangement converting operation of the pixel data can be stabilized and also it can be performed at high speed.  <P>COPYRIGHT: (C)2004,JPO
