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.

Abstract
A mobile communications device. includes a communication unit for communicating with another device. The mobile communications device further has a communication unit for communicating with another device and at least one other component. A controller is connected to the communication unit and the component. The controller can control the component, during at least a part of time the communication unit is in a communicating mode, based on an operation of the communication unit.

18. A light source controller for a mobile communications device comprising a communication unit for communicating with another device in a communicating mode;
- a camera for capturing an image of an object;
a camera controller for controlling said camera, and a light source for illuminating an object in order to enable said camera to capture an amount of light sufficient to capture the image, said light source controller comprising;a controller output connectable to a light source a communication unit for communicating with another device in a communicating mode; the light source controller being connectable to said communication unit and said camera controller, for controlling an emission of light be said light source during at least a part of time said communication unit is in a communicating mode, based on an operation of said communication unit and on an operation of said camera, wherein said light source controller is arranged to control, 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.
- a camera for capturing an image of an object;

19. A method for controlling a mobile communications device, including:
-
communicating by a communication unit in the mobile communication device with another device; capturing an image of an object with a camera in the mobile communications device while illuminating said object by a light source with an amount of light sufficient to capture the image; controlling said light source, when said camera is capturing an image of an object and said communication unit is in said communicating mode, 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; determining a state of said communication unit; 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.
