Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
A display control device (100) for controlling a display unit (D) according to a control signal, which is given from an external device to indicate a fade-in/fade-out process to be performed, characterized in that said display control device comprises: a control means (101) for receiving the control signal and for generating a data change signal on the basis of the control signal; a picture data storage means (102) for storing picture data to be displayed; a color pallet means (103), to which the picture data is inputted from said picture data storage means, for storing pallet data corresponding to displayable colors of the display unit and for outputting the pallet data on the basis of the inputted picture data; a pallet data updating means (104), coupled to said control means and said color pallet means, for gradually updating at least a part of the pallet data in said color pallet means on the basis of the data change signal; and a signal conversion means (105), coupled to said color pallet means, for converting the updated pallet data into display signals and for outputting the display signals to the display unit.
Claim 2
Dependent Claim
50 words
A display control device as claimed in claim 1, characterized in that said pallet data updating means (104) is adapted to gradually change values indicated by the pallet data for each of the displayable colors so that a picture plane on the display unit (D) fades out or fades in.
Claim 3
Dependent Claim
56 words
A display control device as claimed in claim 1, characterized in that said pallet data updating means (104) is adapted to gradually decrease, a predetermined number of times, values indicated by the pallet data for each of the displayable colors by a predetermined value so that a picture plane on the display unit (D) fades out.
Claim 4
Dependent Claim
56 words
A display control device as claimed in claim 1, characterized in that said pallet data updating means (104) is adapted to gradually increase, a predetermined number of times, values indicated by the pallet data for each of the displayable colors by a predetermined value so that a picture plane on the display unit (D) fades in.
Claim 5
Dependent Claim
61 words
A display control device as claimed in claim 1, characterized in that said pallet data updating means (104) is adapted to gradually multiply, a predetermined number of times, values indicated by the pallet data for each of the displayable colors by a predetermined value so that pictures of all the displayable colors on the display unit (D) simultaneously finishes fading out.
Claim 6
Dependent Claim
61 words
A display control device as claimed in claim 1, characterized in that said pallet data updating means (104) is adapted to gradually multiply, a predetermined number of times, values indicated by the pallet data for each of the displayable colors by a predetermined value so that pictures of all the displayable colors on the display unit (D) simultaneously finishes fading in.
Claim 7
Dependent Claim
62 words
A display control device as claimed in claim 1, characterized in that: the data change signal shows a specified color; and said pallet data updating means (104) is adapted to gradually change values indicated by the pallet data for each of the displayable colors so that a picture plane on the display unit (D) fades out and finally has the specified color.
Claim 8
Dependent Claim
61 words
A display control device as claimed in claim 1, characterized in that: the data change signal shows a specified color; and said pallet data updating means (104) is adapted to gradually change values indicated by the pallet data for each of the displayable colors so that a picture plane on the display unit (D) initially having the specified color fades in.
Claim 9
Dependent Claim
65 words
A display control device as claimed in claim 1, characterized in that: the data change signal shows specified colors; and said pallet data updating means (104) is adapted to gradually change values indicated by the pallet data for each of the specified colors so that a picture plane on the display unit (D) fades out or fades in with respect to only the specified colors.
Claim 10
Dependent Claim
59 words
A display control device as claimed in claim 1, characterized in that said pallet data updating means (104) is adapted to replace the pallet data for each of the displayable colors with new pallet data so that a picture plane on the display unit (D) fades out or fades in sequentially with respect to each of the displayable colors.
