Patent ID: 8243132

Claim:
An image output apparatus for assisting an observer who observes an observed person, comprising: an image-capturing section that captures an image of the observed person; an observer's point of sight measuring section that measures a point of sight of the observer when the image-capturing section captures the image of the observed person; an output section that outputs the image of the observed person which is captured by the image-capturing section; and a point of sight output control section that causes the output section to output information indicating the point of sight of the observer which is measured by the observer's point of sight measuring section, together with the image of the observed person which is captured by the image-capturing section; and further comprising: an observed person's information storing section that stores the image of the observed person which is captured by the image-capturing section in association with the observed person; and a previous image output control section that, when the image-capturing section captures a new image of the observed person, causes the output section to output a previous image of the observed person which is stored on the observed person's information storing section in association with the observed person, together with the new image of the observed person which is captured by the image-capturing section, while the observer observes the observed person, wherein the observed person's information storing section further stores the point of sight of the observer which is measured by the observer's point of sight measuring section in association with the observed person, and the previous image output control section causes the output section to output, side by side, both the new image of the observed person with information indicating the observer's point of sight when the new image was captured and the previous image of the observed person with information indicating the point of sight of the observer when the previous image of the observed person was captured.
