  • Patent number: 11409282
    Abstract: A control system for a movable body is mountable on the movable body. The control system includes controllers and a detector. The controllers are configured to control functional systems of the movable body. The detector is configured to detect a movement situation of the movable body. Priorities corresponding to movement situations of the movable body are in advance assigned to each of the plurality of functional systems. When at least one of the plurality of controllers malfunctions, control resources of normal controllers, among the plurality of controllers, which do not malfunction are preferentially distributed to one or more of the functional systems having a high priority according to the movement situation of the movable body at that time.

  • Patent number: 10921701
    Abstract: An image projection apparatus includes: a projector; a projection control apparatus; and a color tone sensor. The projector projects an image. The projection control apparatus causes the projector to perform a projection on a surface of a target serving as a projection target. The color tone sensor detects a color tone of the surface of the target on which an image is projected. The projection control apparatus adjusts a color tone of an image to be projected on a basis of a detection result of the color tone sensor such that the color tone detected by the color tone sensor has a predetermined value.
