To suppress omissions of attached matter detection.SOLUTION: An attached matter detector pertaining to an embodiment comprises a first extraction unit, a second extraction unit, and a detection unit. The first extraction unit extracts a first pixel group in which the luminance gradient of each pixel included in a captured image captured by an imaging device faces outward from a prescribed center region. The second extraction unit extracts a second pixel group in which the luminance gradient of each pixel faces inward toward the center region. The detection unit combines the first pixel group extracted by the first extraction unit and the second pixel group extracted by the second extraction unit and detects attached matter that adheres to the imaging device.SELECTED DRAWING: Figure 1B
【課題】付着物の検出漏れを抑制すること。【解決手段】実施形態に係る付着物検出装置は、第1抽出部と、第2抽出部と、検出部とを備える。第1抽出部は、撮像装置によって撮像された撮像画像に含まれる各画素の輝度勾配が所定の中心領域から外向きの第1画素群を抽出する。第2抽出部は、各画素の輝度勾配が中心領域に向かって内向きの第2画素群を抽出する。検出部は、第1抽出部によって抽出された第1画素群と第2抽出部によって抽出された第2画素群とを組み合わせて撮像装置に付着した付着物を検出する。【選択図】図1B
