Abstract (en)
[origin: EP0526989A2] In a display control device for controlling a display unit (D), a controller (101) receives a control signal from an external device and generates a data change signal from the control signal. A picture data storage unit (102) stores picture data to be displayed. A color pallet unit (103) stores pallet data corresponding to displayable colors of the display unit and outputs the pallet data on the basis of the picture data stored in the picture data storage unit. A pallet data updating unit (104) gradually updates a part or all of the pallet data in the color pallet unit on the basis of the data change signal. A signal conversion circuit (105) converts the updated pallet data into display signals and outputs the display signals to the display unit. <IMAGE>
