Abstract: A mobile terminal device with a camera is provided which can secure emitted light brightness of a camera light unit and save power consumption of the device. During photographing, when the driving power of the camera light unit is increased, driving power for an illumination unit is decreased so that the increase of the total power consumption of the camera light unit and illumination unit can be minimized. In addition, the camera lamp unit and illumination unit are driven by respective driving circuits that share a power supply unit.

Abstract: A repeater amplifier apparatus is provided in which an operator is able to change an operation program of a slave station device without actually visiting to an installation site of the slave station device, thus enabling the operation program to be changed in an efficient manner. The repeater amplifier apparatus includes a master station device for communicating with a base station device, and a slave station device connected to the master station and adapted to communicate with a mobile station device. The master station device comprises a first down repeater for receiving a signal from the base station device to amplify and send it to the slave station device, a first up repeater for receiving a signal from the slave station device and amplify and send it to the base station device, and a first control unit for controlling the master station device.
