Title: Display controller
Inventor: SASAKI SUSUMU
IPC: G09G5/395
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a display controller in which color pallet rewriting time is reduced. SOLUTION: Header data read from a CD-ROM 4, pallet data and bit map data are written into a VRAM 11. A VRAM controller 12 reads the pallet data based on the header data and rewrites a color pallet 13 based on the read data. Then, the bit data are read and outputted to the color pallet 13. The pallet 13 converts the supplied data into RGB color data and outputs the data. Display is conducted at a display device 8 based on the output data of the pallet 13. In the above processes, the controller 12 does not conduct a rewriting of the pallet 13 when the address of previous pallet data and the address of current pallet data agree with each other. By conducting the above processes, the rewriting time of the pallet 13 is reduced.
