Abstract
Apparatus for use with a focus detecting device arranged to repeatedly detect a state of focus, or for use with a camera having such a focus detecting device includes a processor for determining whether the state of focus detected by the focus detecting device is an in-focus state or an out-of-focus state. An indicator provides an indication of the in-focus state in response to the processor determining that the in-focus state has been detected. The processor causes the indication provided by the indicator to vary on the basis of a number of times that the in-focus state has been determined by the processor.
