Abstract:
There is provided a camera apparatus including: a capturing unit that includes a lens to which light, from a capturing area including IR light and visible light is incident, and that performs capturing based on the light; an IR lighting unit that irradiates the capturing area with IR light; and a controller that generates an instruction to change a focal position of the lens and an instruction to adjust a quantity of the IR light, in which the controller calculates an IR light ratio which indicates a ratio of the quantity of the IR light to the light included in a captured image of the capturing area, and selects and performs any one of a first focusing processing to change the focal position of the lens corresponding to the IR light, a second focusing processing to change the focal position of the lens corresponding to the visible light, and an IR light quantity adjustment determination processing to determine whether or not to adjust the quantity of the IR light, based on the IR light ratio.
