The control unit receives an input of the identification information or information for designating the identification from an external apparatus, an external memory, or an inner memory of the camera, and displays, on the electric paper display unit, the identification information or synthesized information including the identification information and additional information. Further, an electric paper display module includes a secure memory in which an option key for defining a process that is executable in the camera apparatus is stored.

Display apparatus, camera apparatus, and method

A detection apparatus includes a first acquisition part that acquires information about a suppliable electric power of a power supply apparatus that supplies an electric power to a power reception apparatus via a transmission path; a second acquisition part that acquires information about a supply electric power output from the power supply apparatus, including information about a supply voltage output from power supply apparatus; a third acquisition part that acquires information about a voltage applied to the power reception apparatus after a voltage drop in the transmission path; and a margin information calculation part that calculates first margin information about a margin of a supply electric power, and calculates second margin information about a margin of the voltage drop.
