PROBLEM TO BE SOLVED: To provide a display controller which suppresses the degradation in system performance and the deterioration of image quality, and to provide an electronic equipment and a supply method of image data. SOLUTION: The display controller 20 includes: a first memory 22 which memorizes the image data and is accessed by a sequential access operation shorter in access time than the random access operation time; a second memory 24 which is smaller in the electric power consumption during the access operation than the first memory 22 and memorizes the image data; and a data transfer controller 30 performs the transfer control of the image data from the first memory 22 to the second memory 24. The data transfer controller 30 performs the transfer control of the image data from the first memory 22 to the second memory 24, and performs the control to transfer the image data obtained after the image processing to the image data written to the second memory 24, from the second memory 24 to the first memory 22. The display controller 20 supplies the image data of the first memory 22 to a display driver 30. COPYRIGHT: (C)2009,JPO&INPIT
