Abstract
A camera capable of automatic focusing operation includes a picture-taking lens, photoelectric detector elements for photoelectrically detecting the light from an object to be photographed, a picture-taking lens driving device for driving the picture-taking lens to the in-focus position on the basis of the output of the photoelectric detector elements, a drive blocking device for detecting that the object is unsuitable for automatic focusing operation, thereby blocking the driving of the picture-taking lens by the picture-taking lens driving device, information detecting apparatus for detecting the information of the object, a memory for storing the output of the information detecting apparatus when the object is unsuitable for automatic focusing operation, and a releasing device for comparing the output of the information detecting apparatus with the output of the memory and releasing said blocking by the drive blocking device when the two outputs differ from each other.
