Abstract: A first content image and a second content image is acquired, a first content image has first color information, a first pattern image having a first color scheme is determined based on the first color information, the first content image is displayed on a screen, the first pattern image is displayed on the screen after displaying the first content image, and the second content image is displayed on the screen after displaying the first pattern image.

Abstract: [Problem] To provide a new way for fixing carbon dioxide under mild conditions and with high efficiency. [Solution] The material for carbon dioxide fixation according to the present invention contains a metal ion donor and an amine as a precursor of a bridging ligand. The amine is configured to react with a gaseous carbon dioxide to form the bridging ligand having at least one carbamate anion moiety. The bridging ligand is configured to react with the metal ion donor to form a coordination polymer in which a plurality of the metal ions is linked by the bridging ligand.

Abstract: A method for controlling a projection system including a projector and a portable apparatus including a camera includes causing the projector to project light representing a pattern image, acquiring image data from the camera that captures the light, determining a path in the pattern image based on a change in the image data according to displacement of the camera, and generating a filter that changes a portion of an image projected by the projector in the range defined by the path.
