PURPOSE:To remove failure in photographing by lying in wait and to photograph an object which should be photographed only when the object exists in a screen by calculating the similitude between the data of the object outputted from an image sensor in a 1st time and the data of the object in a 2nd time. CONSTITUTION:The image sensor 14 receives light concerning the object and a focusing state is detected in a focusing state detection means 15 based on the output from the image sensor 14 so as to store the data of the object outputted from the image sensor in the 1st time in a storage means 16. And the similitude between the stored data of the object and the data of the object outputted from the image sensor 14 in the 2nd time latter than the 1st time is calculated. When the similitude exceeds a specified value, a similitude arithmetic means 17 generates an output signal to execute photographing actions in a photographing means 18 based on the signal. Since the sequence of photographing is executed after conforming the existence of the object, probability that the object, which is not a target, is photographed by mistake can be decreased. |
