DRIVING ASSISTANCE DEVICE, DRIVING ASSISTANCE METHOD, AND RECORDING MEDIUM

A driving assistance device includes a processor connected to a memory. The processor detects a latent recognition region that is unconsciously recognized by a human in an entire imaging region of a captured image. The captured image is captured by an external camera that is provided in a mobile body. The captured image is an image of at least a traveling direction in which the mobile body travels. The latent recognition region is detected based on a predetermined feature value included in the captured image. The processor presents predetermined driving assistance information in a region on a display device. The region is estimated in accordance with the detected latent recognition region.
