PROBLEM TO BE SOLVED: To provide a light distribution device for distributing incident illumination light.SOLUTION: The present invention provides a light distribution device for distributing illumination light to a light distribution target region in a light distribution target, the device comprising: an information acquisition part that acquires the information indicating a light distribution target region a controller that calculates a hologram according to the information and a spatial light modulator into which illumination light enters and which distributes the illumination light to the light distribution target region by the hologram. The light distribution device also has an image processing part which acquires an extracted image acquired by extracting the light distribution target region from a photographed image of the light distribution target photographed by the information acquisition part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】入射された照明光を配光する配光装置を提供する。【解決手段】配光対象における配光対象領域に照明光を配光する配光装置であって、配光対象領域を示す情報を取得する情報取得部と、情報に応じたホログラムを計算する制御部と、照明光が入射され、ホログラムにより照明光を配光対象領域に配光する空間光変調器とを備える配光装置を提供する。また、当該情報取得部は、配光対象を撮影し、撮影した画像から配光対象領域を抽出した抽出画像を取得する画像処理部を更に備える配光装置を提供する。【選択図】図1
