1. An image recording apparatus for assisting an observer who observes an observed person, comprising: an image-capturing section that captures the image of the observed person; an observation result input section that inputs a result of the observation done on the observed person by the observer; an observer's point of sight position judging section that judges whether the observer looks at the observed person when the image-capturing section captures the image of the observed person; an image extracting section that extracts an image of the observed person for which the observer's point of sight position judging section judges that the observer looks at the observed person; a physical status quantifying section that quantifies a physical status of the observed person by analyzing the image of the observed person which is extracted by the image extracting section, for an observation result which is input by the observation result input section and corresponds to the image of the observed person which is extracted by the image extracting section; and a physical status data storing section that stores thereon physical status quantified data which is generated by the quantification by the physical status quantifying section, in association with the corresponding observation result.
