  • Publication number: 20210337102
    Abstract: The present invention makes it possible to perform good illumination and obtain a good captured image when a plurality of users each having a camera-equipped portable information terminal device gather in the same place. A camera-equipped portable information terminal device is provided with: an imaging unit that captures an image of a subject; a first illumination means for illuminating the subject; a first communication unit that communicates with other portable information terminal devices; and a first control unit that controls the imaging unit and the first communication unit. The first control unit transmits a light emission instruction signal to the other portable information terminal devices via the first communication unit, and causes a second illumination means of each of the other portable information terminal devices to emit light in tandem with an imaging operation of the imaging unit.
