Patent number: 11393128Abstract: An adhered substance detection apparatus of an embodiment includes a calculator and a determiner. The calculator calculates an edge feature for each cell based on edge vectors of pixels within the cell in a captured image, and further calculates a region feature for each unit region based on the calculated edge features of the cells within the unit region. The determiner determines an adherence state of an adhered substance on a lens of a camera based on the region feature. The calculator calculates, as the region feature, number of the cells having an edge strength of zero. When the number of the cells having the zero edge strength is equal to or greater than a predetermined number in a predetermined attention area in the captured image, the determiner determines not to perform a determination for detecting whether the lens of the camera is entirely covered by the adhered substance.Type: GrantFiled: September 11, 2020Date of Patent: July 19, 2022Assignee: DENSO TEN LimitedInventors: Daisuke Yamamoto, Nobunori Asayama, Nobuhisa Ikeda, Yasushi Tani, Takashi Kono, Daisuke Shiota, Teruhiko Kamibayashi
