Abstract: The purpose of the present invention is to provide a novel anthraquinone compound, and to provide: a dichroic dye constituted of the novel anthraquinone compound; a liquid crystal composition which contains the dichroic dye; and preferably a dimming element having excellent contrast and light resistance and containing said composition. The present invention discloses an anthraquinone compound represented by formula A below (wherein R1 represents a C3-16 branched alkyl group, and R2 represents a hydrogen atom, a C1-8 straight-chain or branched alkyl group, or a C1-8 straight-chain or branched alkoxy group). In addition, the present invention discloses a liquid crystal composition including the anthraquinone compound and a liquid crystal material, and a dimming element containing said composition.

Abstract: A video processing device includes a state memory storing a plurality of setting states of each setting related to video processing; a state applying processor configured to apply the setting states to the settings related to the video processing; a history memory setting a series of changes in the settings related to the video processing as a change history of one group and store a plurality of change histories of the one group; a history reproduction processor reproducing the series of changes of the settings; an execution sequence memory configured to store a sequence of the setting states to be applied among the plurality of setting states and the change histories; and a sequencer configured to execute the application of the setting states by the state applying processor and the reproduction of the change histories by the history reproduction processor in the sequence stored in the execution sequence memory.
