A detecting device compares, with a threshold value, a difference or ratio between values of information on distances or defocused states of two distributed points in a distribution of distances or defocused states in an object space and determines whether two areas corresponding to the two distributed points represent one and the same object according to the result of comparison. The detecting device sets the threshold value at a value based on the information on distances or defocused states of the two distributed points subjected to determination, so that fluctuations of the determination taking place depending on distances or defocused states can be lessened.

[ I claim:] [1.] A distance detecting device which makes a comparison between a difference or ratio between values of information on distances of two distributed points and a threshold value on the basis of information on a distribution of distances in an object space and determines, in accordance with a result of the comparison, whether two areas corresponding to the two distributed points represent one and the same object, said distance detecting device being characterized in that:said threshold value is set at a value based on the information on distances of the two distributed points subjected to determination.
