Abstract: A communication terminal includes circuitry. The circuitry is configured to calculate, for each of a plurality of captured-image data items that are obtained by continuous image capturing, a center point of an object detection area of the captured-image data item. The circuitry is further configured to render a heat map image having a gradation of color, the gradation of color of the heat map image being determined based on weighting of colors of the heat map image with the calculated center points of the captured-image data items. The circuitry is further configured to map the heat map image on a captured-image represented by one of the plurality of captured-image data items. The circuitry is further configured to display the captured-image on which the heat map image is mapped.

Abstract: An image management apparatus controls a display of a captured image, the apparatus being connected to a communication terminal through a network. The apparatus includes a receiver and circuitry. The receiver receives, from the communication terminal, an instruction for displaying a drawn image drawn by a user on a captured image while the captured image is being displayed to the user, the captured image being a full spherical panoramic image. The circuitry generates an attachment image containing the drawn image, and attaches the attachment image containing the drawn image to the captured image, the attachment image containing the drawn image being a planar image.

Abstract: An output system is provided that includes at least one output apparatus configured to output content information. The output system includes a determination part configured to determine, based on the content information, whether to generate first control information for switching the output apparatus to a power-saving mode, the first control information being generated with respect to the output apparatus that does not have to output the content information. The output system further includes a control information generation part configured to generate the first control information when the determination part determines that the first control information has to be generated and a power control part configured to switch the output apparatus to the power-saving mode based on the first control information.
