1. A camera comprising:
- a vibration detecting portion for detecting a vibration state of the camera;
a first operating member for setting a camera mode to a vibration detecting mode for operating the vibration detecting portion;
a second operating member for setting a strobe light emitting mode of the camera; and
a control portion for controlling implementation and termination of operation of the vibration detecting portion in accordance with a type of the strobe light emitting mode set by the second operating member when the vibration detecting mode is set.

Abstract
A camera having a camera-blur warning function which is adapted to switch between executing a camera-blur detecting mode and stopping the camera-blur detecting mode by the setting of a camera strobe mode. In a photographing scene where occurrence of a camera-blur is on a user'"'"'s mind, a camera-blur detecting mode is set, thereby to detect vibration. In case any camera-blur occurs, warning is made so that the user may recognize it. Furthermore, at the time of determining holding, a conventional optical sensor which is already mounted as a sensor for measuring distance is utilized for determining the camera-blur.
