Human Factors
The problem arose after being switched to VFR from Approach on approach to JNX.  I then listened to ATIS and while I received most of the information I missed the fallout of the UNICOM frequency change from what is listed on the VFR sectional.  Wind was out of 070 so I entered 45 to left downwind for Runway 03.  There was also a helicopter inbound on the same frequency as me.  After turning final and configuring for landing I visually checked the runway and noticed a small aircraft departing Runway 21.  At that moment the traffic and I both deviated right leaving ample safe distance between planes.  Both returned for landing and exchanged information.The main factors that caused this on my end were distractions in the airplane.  While I was listening to the ATIS my passengers were training on our camera system obstructing the ATIS at times.  Another factor that came into play is the flexible nature of aerial survey flying and frequent diversions.I have taken away the importance of mitigating distractions and careful preflight planning from this event.
Pilot reports that during transition to VFR from Approach; pilot felt rushed and missed JNX airport ATIS information; resulting in a conflict.
