If an object were dependent on only one mind for its existence and were not perceived by that mind would it then exist?

the truth is we have the so-called subjective reality and objective reality. if one say that an object owes its existence in the mind of the subject or the person, then this is what we call subjective truth. on the other hand, we have the objective reality of knowing the truth of an object, meaning basing on an objective truth of the object's existence it will still exist even if not perceived by the mind because it has its own objective reality of existence. the example for this will be "man". we can still conceive the idea of man even if we don't see a man.
