A diagnosis supporting device comprising: a display; an imaging unit (202, 204) configured to capture a subject; an eye gaze detector configured to detect an eye gaze direction of the subject from a captured image captured by the imaging unit (202, 204); a gaze point detector configured to detect a gaze point of the subject in a display region of the display, based on the eye gaze direction; an output controller configured to display, on the display, any of a plurality of diagnosis images, grouped into different groups such that similar diagnosis images belong to the same group, to diagnose developmental disorder, select a diagnosis image to be displayed next from the plurality of diagnosis images according to positions of the gaze point detected when the diagnosis image is displayed; and an evaluator configured to calculate an evaluation value of the subject indicating the degree of the developmental disorder of the subject, wherein the evaluation value is obtained by the number of gaze points detected in the predetermined region to the total number of the detected gaze points, or by a total time in which the gaze point is detected within the predetermined region to a total time in which the gaze point is detected, and wherein the degree of developmental disorder is higher as the evaluation value is lower, characterized in that the output controller is configured to, i) select a different diagnosis image to be displayed next from the same group as the currently displayed image, when the evaluation value is less than a predetermined threshold and the degree of developmental disorder of the subject is high, ii) select a different diagnosis image to be displayed next from a different group as the currently displayed image, when the evaluation value is equal to or more than the predetermined threshold and the degree of developmental disorder of the subject is low. a display; an imaging unit (202, 204) configured to capture a subject; an eye gaze detector configured to detect an eye gaze direction of the subject from a captured image captured by the imaging unit (202, 204); a gaze point detector configured to detect a gaze point of the subject in a display region of the display, based on the eye gaze direction; an output controller configured to display, on the display, any of a plurality of diagnosis images, grouped into different groups such that similar diagnosis images belong to the same group, to diagnose developmental disorder, select a diagnosis image to be displayed next from the plurality of diagnosis images according to positions of the gaze point detected when the diagnosis image is displayed; and display, on the display, any of a plurality of diagnosis images, grouped into different groups such that similar diagnosis images belong to the same group, to diagnose developmental disorder, select a diagnosis image to be displayed next from the plurality of diagnosis images according to positions of the gaze point detected when the diagnosis image is displayed; and an evaluator configured to calculate an evaluation value of the subject indicating the degree of the developmental disorder of the subject, wherein the evaluation value is obtained by the number of gaze points detected in the predetermined region to the total number of the detected gaze points, or by a total time in which the gaze point is detected within the predetermined region to a total time in which the gaze point is detected, and wherein the degree of developmental disorder is higher as the evaluation value is lower, characterized in that the output controller is configured to, i) select a different diagnosis image to be displayed next from the same group as the currently displayed image, when the evaluation value is less than a predetermined threshold and the degree of developmental disorder of the subject is high, ii) select a different diagnosis image to be displayed next from a different group as the currently displayed image, when the evaluation value is equal to or more than the predetermined threshold and the degree of developmental disorder of the subject is low. i) select a different diagnosis image to be displayed next from the same group as the currently displayed image, when the evaluation value is less than a predetermined threshold and the degree of developmental disorder of the subject is high, ii) select a different diagnosis image to be displayed next from a different group as the currently displayed image, when the evaluation value is equal to or more than the predetermined threshold and the degree of developmental disorder of the subject is low.
