VISUAL STATE DETECTION APPARATUS, VISUAL STATE DETECTION METHOD, AND VISUAL STATE DETECTION PROGRAM

摘要

To provide a visual recognition state detection apparatus capable of estimating the presence/absence of visual recognition based on target visual difficulty and gaze behavior characteristics.SOLUTION: A visual recognition state detection apparatus 1000 for detecting a visual recognition state of a target person 2, is provided with a camera 30 for capturing an image of an area including a visual target object 4 for the target person 2, a visual line detection unit 4004 for detecting a visual line direction of the target person 2, a visual recognition difficulty estimation unit 4006 for estimating the visual recognition difficulty of the target person 2 in the image captured by the camera 30 based on a relationship between a factor given to visual characteristics of object 4 and the visual recognition difficulty for the target object 4, and a visual recognition state determination unit 4010 for determining the visual recognition state by a discriminator for receiving, as inputs, the position of the target object 4 in the image captured by the camera 30 and the visual line direction detected by the visual line detection unit 4004.SELECTED DRAWING: Figure 1
