ABSTRACT:
This invention provides a display illuminating apparatus for use in a camera, which is operable without generating great noise and hence permits at least the AF and AE operations of the camera to be performed without the influence of noise, and which enables the operator of the camera to confirm the present operation. Information on photography by the camera is displayed on an LCD lit by an EL that is driven by an EL driving circuit. Further, a remote control switch incorporated in a switch input section of the camera sets the camera in a state in which it can receive a remote control signal. Where the camera is set in a remote control mode by the remote control switch, the operation of the EL driving circuit is stopped by an instruction from a CPU, thereby inhibiting lighting of the EL.
