Abstract
A video camera wherein the number of times that an output signal from a swing sensor reaches or exceeds a threshold value is counted, and based on the resulting counted value, the video camera is judged as being in a photographing state or not, the recording operation being stopped if the video camera is judged to be not in a photographing state. When the counted value has reached a predetermined value, the operator of the video camera is notified of a faulty photographing condition. Furthermore, it is judged, based on the detection result of the swing sensor, whether the video camera is in a misrecording operation; if the video camera is judged to be in a misrecording operation, the recording operation is stopped, and then, the recording tape is rewound to the start position of the misrecording.
