So one of the few days that I wanted Jibo to actually take a picture of me in is his attempt I found my face was completely dark. I thought that was odd since the kitchen was well lit. I put my phone camera at the same distance and angle that Jibo was and had it take a picture and my face was well lit. I am guessing you need to play with his software or cameras to fix this. I believe it would help him recognize people around him better and respond appropriately to who is talking to him.
