Default Cofusing problem with my rear-view camera

hi
I've installed an aftermarket rearview camera and I've been faced with a confusing problem
sometimes it's ok but when i park in outdoor camera dose not work properly and LCD showes a black and white picture (picture flickering)
when camera is ok I have checked it's signal and it's about 1.2V but when it doesn't work properly signal is changing from .3V to 1.2V
I found the solution by chance:
when car is in reverse-gear if someone put his hands or somthing near the rear camera problem will be fixed and LCD will show the correct picture!!!
Does anyone know the problem?

Appears to be related to the ambient light sensor? That might be why it is affected by indoor vs. outdoor and why blocking the light helps. Seems that would be a wiring issue, maybe internally.

It was about gain control problem and camera should be changed as it was water proof
