Abstract
Operation situations of a plurality of functions of the camera can be checked from a front of the camera without adding any new hardware. A self-timer LED which is previously provided on a front of the camera is also used as an indicating device which indicates operation situations of other functions of the camera. That is, operation situations such as charging a rechargeable battery or communicating with a personal computer are indicated by lighting, blinking, or the like of the self-timer LED. Especially, when a digital camera is mounted to a cradle used in charging the battery or communicating with the personal computer, the operation situations such as charging or communicating can be effectively checked from the front of the camera. Further, for a digital camera which has a moving image-capturing function or a voice recording function, moving image recording or voice recording is indicated by lighting, blinking, or the like of the self-timer LED.
