To provide an object information generation device, a processor and a data processing system capable of quickly generating information regarding the presence or absence of an object at a low load.SOLUTION: An object information generation device 1 includes a light source 11, a projection optical system 12 for projecting projection light emitted from the light source 11 to a target region, an imaging device 22 for receiving reflected light which is the projection light reflected from an object existing in the target region, a light receiving optical system 21 for condensing the reflected light on a light receiving surface 22a of the imaging device 22, a control unit 32, a reception unit 31 for accepting settings regarding a distance range for object detection, and a signal processing unit 35 for processing detection signals output from each pixel of the imaging device 22 and generating information on the presence or absence of an object existing in the distance range. After the projection light is projected to the light source 11, the control unit 32 sets each pixel on the imaging device 22 to the exposure state at a timing and a time width corresponding to the distance range set via the reception unit 31.SELECTED DRAWING: Figure 1 【課題】低負荷で迅速に物体の有無に関する情報の生成処理を行うことが可能な物体情報生成装置、処理装置およびデータ処理システムを提供する。【解決手段】物体情報生成装置１は、光源１１と、光源１１から出射された投射光を目標領域に投射する投射光学系１２と、目標領域に存在する物体に投射光が反射された反射光を受光する撮像素子２２と、撮像素子２２の受光面２２ａに反射光を集光させる受光光学系２１と、制御部３２と、物体検出の対象とされる距離範囲の設定を受け付ける受付部３１と、撮像素子２２の各画素から出力される検出信号を処理して距離範囲に存在する物体の有無に関する情報を生成する信号処理部３５と、を備える。制御部３２は、光源１１に投射光を投射させた後、受付部３１を介して設定された距離範囲に対応するタイミングおよび時間幅において、撮像素子２２上の各画素を露光状態に設定する。【選択図】図１
