To solve the problem that a nurse has to select a standby image of a liquid crystal corridor lamp of a nurse call installed in the corridor of a sickroom only from the ones set beforehand and customizability is low.

An input part for image selection is provided in a bedside terminal installed at each bedside of a patient so that the patient can select an image that he/she likes. Also, a display part for operating software for drawing for image processing is provided in the bedside terminal so that the patient himself/herself can produce the image of a corridor lamp.
