Abstract: An illuminator includes: a light emitter including a light-emitting diode; a temperature sensor configured to detect a current temperature of the light emitter; and an illumination controller configured to adjust a drive voltage being supplied to the light emitter in accordance with the current temperature. The illumination controller includes a reference temperature storage in which a reference temperature is stored in advance and is configured to adjust the drive voltage by detecting the current temperature from the temperature sensor on a constant time cycle and comparing the current temperature with the reference temperature.

Abstract: An information processing apparatus according to an embodiment of the present technology includes a detection unit, an estimation unit, and a prediction unit. The detection unit detects a target object from an input image. The estimation unit estimates a posture of the detected target object. The prediction unit predicts an action of the target object on a basis of the estimated posture.

Abstract: Disclosed is a multiprojection system in which an image can be freely projected by plural projectors so that projected images of the plural projectors are arranged in lines longitudinally and laterally and all of the projected images become one image; an entirely enlarged image or divided images can be projected; or an individual image can be projected, which comprises each of the plural projectors being provided independently with a pan driving device and a tilt driving device so that the direction of projection can be freely changed; and having at least one of functions of changing the direction of projection, the position of a projected image, the synthesis, shape or arrangement of an image and/or the size of an image and displaying each image in a flying state to constitute a screen image system harmonized with lighting in a representation space.
