If the police take a camera as evidence, do they use all illegal things on the camera as evidence or just the ones pertaining to the case?

I got into trouble a while ago, and I have court tomorrow. I had my camera with me and they took it as evidence against me. they put in the police report the things on it pertaining to the case, but there are other videos on the camera of illegal things that have nothing to do with the case, or anything I can be charged with, but will they bring up the other videos as a kind of like a addition to my profile? I will have family there and if they see the videos it will be bad. keep in mind I’m a minor and the charge is criminal mischief.
