A remote imaging method for carrying out imaging by a camera placed at an imaging spot, the method comprising: imaging a plurality of images of a person having an operating terminal in the imaging spot by the camera; obtaining a display content displayed on a display of the operating terminal from the plurality of taken images; determining whether or not the operating terminal has imaging authority; and sending a specified image taken by the camera at a time for imaging specified by the operating terminal determined to have the imaging authority to the operating terminal, wherein the determining further includes assessing whether or not the obtained display content and temporal transition of the obtained display content make a predetermined pattern, and when an assessment result is positive, the determining determines that the operating terminal has the imaging authority; the predetermined pattern is to display each of a plurality of authentication images on the display of the operating terminal for display time defined in advance in an order defined in advance; wherein the camera has a clock and a storage unit, the operating terminal has a clock, and wherein the remote imaging method further comprises receiving, from the operating terminal, a start display time and date measured by the clock belonging to the operating terminal at a start of displaying each of the plurality of authentication images by the operating terminal; storing in the storage unit of the camera the plurality of taken images in association with taken time and date measured by the clock belonging to the camera when taking each of the plurality of taken images; and calculating a clock time difference indicating a gap between a time and date measured by the clock belonging to the camera and a time and date measured by the clock belonging to the operating terminal using the start display time and date of one image and the taken time and date of the one image. imaging a plurality of images of a person having an operating terminal in the imaging spot by the camera; obtaining a display content displayed on a display of the operating terminal from the plurality of taken images; determining whether or not the operating terminal has imaging authority; and sending a specified image taken by the camera at a time for imaging specified by the operating terminal determined to have the imaging authority to the operating terminal, wherein the determining further includes assessing whether or not the obtained display content and temporal transition of the obtained display content make a predetermined pattern, and when an assessment result is positive, the determining determines that the operating terminal has the imaging authority; the predetermined pattern is to display each of a plurality of authentication images on the display of the operating terminal for display time defined in advance in an order defined in advance; wherein the camera has a clock and a storage unit, the operating terminal has a clock, and wherein the remote imaging method further comprises receiving, from the operating terminal, a start display time and date measured by the clock belonging to the operating terminal at a start of displaying each of the plurality of authentication images by the operating terminal; storing in the storage unit of the camera the plurality of taken images in association with taken time and date measured by the clock belonging to the camera when taking each of the plurality of taken images; and calculating a clock time difference indicating a gap between a time and date measured by the clock belonging to the camera and a time and date measured by the clock belonging to the operating terminal using the start display time and date of one image and the taken time and date of the one image.
