  This paper is the report of the first Under-Display Camera (UDC) image
restoration challenge in conjunction with the RLQ workshop at ECCV 2020. The
challenge is based on a newly-collected database of Under-Display Camera. The
challenge tracks correspond to two types of display: a 4k Transparent OLED
(T-OLED) and a phone Pentile OLED (P-OLED). Along with about 150 teams
registered the challenge, eight and nine teams submitted the results during the
testing phase for each track. The results in the paper are state-of-the-art
restoration performance of Under-Display Camera Restoration. Datasets and paper
are available at https://yzhouas.github.io/projects/UDC/udc.html.
