A diagnosis assisting apparatus includes a display, imaging units (202 and 204) for imaging a subject, a line of sight detecting unit (351) for detecting a line of sight direction of the subject from a picked-up image imaged by the imaging units (202 and 204), a point of view detecting unit (352) for detecting a point of view of the subject in a display region on the display based on the line of sight direction, an output controller (354) for displaying a diagnostic image including a natural image and a geometrical image similar to the natural image on the display, and an evaluation unit (359) for evaluating a degree of developmental disorder of the subject based on the point of view detected by the point of view detecting unit (352) when the diagnostic image is displayed.
