IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

WIPO Patent Application WO/2020/039838

A1

The present invention realizes an image processing device that can improve preceding-target tracking accuracy by appropriately performing switching processing of a template in accordance with changes in a light source state of a preceding target at night. The present invention performs usual template processing (step S210) without performing template exchanging processing if light spot information of a tracking vehicle does not change (step S204). If the light spot information has changed, confirmation is made as to whether a template image corresponding to present light spot information exists in a template storage unit or not (step S205), a template image according to the light spot is selected when the template image corresponding to present light spot information exists (S206), and template exchange is performed (step S207). In Step S205, when the template corresponding to the light spot does not exist in the template storage unit, a template image corresponding to the light spot is newly created (step S208), and the new template image and the light spot information are associated together and stored in the template storage unit (step S209).
