Abstract: An image processing device for a projection system includes an image generation unit and a brightness acquisition unit, and the image generation unit generates data for projecting the specific image, as a first portion in the first data for display, which corresponds to the first superimposed region, generates a second portion in the first data for display, which corresponds to the first non-superimposed region based on first input image data in the data of the projection target image, which corresponds to the first non-superimposed region, and the second brightness, and generates a third portion in the second data for display, which corresponds to the second superimposed region based on second input image data in the data of the projection target image, which corresponds to the second superimposed region, and the first brightness.

Abstract: An image forming apparatus includes: an image forming section that forms an image on a document; a first ejection section that ejects the document on which the image has been formed; an exterior portion which is movable and a part of which constitutes an exterior of the apparatus; an entrance portion that is exposed by movement of the exterior portion and that constitutes an entrance for the document to be transported to an image reading section that reads the image formed on the document; the image reading section that reads the image formed on the document transported after the entrance portion is exposed; and a second ejection section that ejects the document which has been read by the image reading section. An ejecting direction of the first ejection section, an ejecting direction of the second ejection section, and a moving direction of the exterior portion coincide with each other.

Abstract: A projection apparatus includes a projection portion that performs irradiation with projection light, and a moving mechanism that moves a projection range of the projection light. In a state where the projection range is maintained, the projection apparatus displays an image showing a movement destination of the projection range in response to a first operation by the projection portion. The projection apparatus moves the projection range to the movement destination by the moving mechanism.

Abstract: A node is included in a communication control system including a plurality of nodes 31, and a master device 30 for performing flow control of multihop communication in a network including the plurality of nodes 31. To the node 31 in use of second service, a time obtained by subtracting, from a frame period of the network, a total one frame transmission time of each node, used for first service is allocated as one frame transmission time used for second service having a priority set lower than that of the first service.
