Where do Sony Android phones store deleted pictures? I was thinking to copy the specific file to my PC and scan it with third party application. Is this possible?
Like Death Mask Salesman said, there is not an Android recycle bin. However, there are apps you can download on your PC to scan your phone and potentially recover a deleted photo. Here are a few (note: I haven't tried any of these and am not affiliated with any of them):

Good luck!
