Abstract
The present invention relates, in a camera including multiple points type focus detecting means, to the camera for carrying out the proper control for a time for accumulation when detecting a focus by adopting fill-in light. In particular, the invention provides a camera which is designed in such a way that in the control for the time for accumulation for the focus detection without the emission of the fill-in light, the maximum time for the accumulation is determined in accordance with the accumulation time in a sensor in which the accumulation operation control has been most early completed, while for the focus detection in a state in which the fill-in light is being applied to an object, the maximum time for the accumulation is determined irrespective of the accumulation time in a sensor in which the accumulation operation control has been most early completed.
