An image interpretation support apparatus comprising: a candidate lesion portion extracting unit configured to analyze an image to be interpreted and to extract a candidate lesion portion from the image to be interpreted; a display unit that is configured to display the image to be interpreted and support information indicating the candidate lesion portion; a line-of-sight detecting unit configured to detect a line of sight of a radiologist; a gaze determining unit that is configured to determine, in accordance with a detection result obtained by the line-of-sight detecting unit, whether the candidate lesion portion in the image to be interpreted that is displayed on the display unit has been gazed at by the radiologist; a completion detecting unit configured to detect completion of image interpretation, by the radiologist, of the image to be interpreted that is displayed on the display unit; a display control unit that, in a case where the completion detecting unit detects the completion of image interpretation and the gaze determining unit determines that the candidate lesion portion has not been gazed at, is configured to switch from a first display state in which the image to be interpreted is displayed on the display unit and the support information is not displayed to a second display state in which at least the support information is displayed on the display unit; a fatigue deducing unit configured to deduce whether the person who reads the image needs recovery from fatigue caused by the image interpretation; and a warning unit configured to output a warning in a case where the fatigue deducing unit deduces that the recovery from fatigue is needed, wherein the fatigue deducing unit is configured to deduce whether the recovery from fatigue is needed by using the number of switching operations from the first display state to the second display state, performed by the display control unit. a candidate lesion portion extracting unit configured to analyze an image to be interpreted and to extract a candidate lesion portion from the image to be interpreted; a display unit that is configured to display the image to be interpreted and support information indicating the candidate lesion portion; a line-of-sight detecting unit configured to detect a line of sight of a radiologist; a gaze determining unit that is configured to determine, in accordance with a detection result obtained by the line-of-sight detecting unit, whether the candidate lesion portion in the image to be interpreted that is displayed on the display unit has been gazed at by the radiologist; a completion detecting unit configured to detect completion of image interpretation, by the radiologist, of the image to be interpreted that is displayed on the display unit; a display control unit that, in a case where the completion detecting unit detects the completion of image interpretation and the gaze determining unit determines that the candidate lesion portion has not been gazed at, is configured to switch from a first display state in which the image to be interpreted is displayed on the display unit and the support information is not displayed to a second display state in which at least the support information is displayed on the display unit; a fatigue deducing unit configured to deduce whether the person who reads the image needs recovery from fatigue caused by the image interpretation; and a warning unit configured to output a warning in a case where the fatigue deducing unit deduces that the recovery from fatigue is needed, wherein the fatigue deducing unit is configured to deduce whether the recovery from fatigue is needed by using the number of switching operations from the first display state to the second display state, performed by the display control unit.
