1. A mobile communications device, comprising:

  • a communication unit for communicating with another device;

    a camera for capturing an image of an object;

    a camera controller for controlling said camera; and

    a light source for illuminating said object in order to enable the camera to capture an amount of light sufficient to capture the image;

    a light source controller having a controller output connected to said light source, for controlling said light source,wherein the light source controller is connected to said communication unit and said camera controller, for controlling, when said camera is capturing an image of an object and said communication unit is in said communicating mode, said light source to emit light having an intensity which is sufficient to provide an effective illumination of the object and which depends on the power consumption of the communication unit; and

    wherein said light source controller is connected to an control output of said communication unit, for determining a state of said communication unit and to a control input of said light source for changing a state of said light source from a first state to a second state at which said light source has a lower energy consumption than in said first state when said communication unit enters into a predetermined state during at least a part of said communicating mode.
