No it is NOT.The condition to end hiding is being clearly seen.
Hiding ends when you leave a hiding spot and enter a place you cannot Hide, at which point you are automatically detected unless your target is 'distracted'.
The rules expressly say so:
In combat, most creatures stay alert for signs of danger all around, so if you come out of hiding and approach a creature, it usually sees you. However, under certain circumstances, the DM might allow you to stay hidden as you approach a creature that is distracted, allowing you to gain advantage on an attack roll before you are seen.
Hiding also ends if you make an attack, or make a loud noise or otherwise reveal yourself.
