PROBLEM TO BE SOLVED: To provide a camera with a camera shake determining function capable of accurately determining a camera shake at a low cost and with a simple constitution. SOLUTION: The camera is provided with an image signal detecting means for detecting an object image signal, a vibration detecting means for receiving the detection results of the object image signal detected by the image signal detecting means at every prescribed cycle and then detecting the vibrated state of the camera in accordance with a time change of the object image signal, a photometry means for measuring luminance required to calculate a shutter speed at the exposure, an allowable vibration quantity calculating means for calculating the allowable vibration quantity at the exposure in accordance with the focal distance and the shutter speed of the camera, a camera shake determining means for determining the camera shake based on the output of the vibration detecting means and the output of the allowable quantity calculating means, and a warning means for giving a warning when the occurrence of the camera shake is decided by the camera shake determining means, and the determining method by the camera shake determining means is changed in accordance with the output of the vibration detecting means.
