Removing diffraction image artifacts in under-display camera via dynamic skip connection network
Abstract Recent development of Under-Display Camera (UDC) systems provides a true
bezel-less and notch-free viewing experience on smartphones (and TV, laptops, tablets),
while allowing images to be captured from the selfie camera embedded underneath. In a
typical UDC system, the microstructure of the semi-transparent organic light-emitting diode
(OLED) pixel array attenuates and diffracts the incident light on the camera, resulting in
significant image quality degradation. Oftentimes, noise, flare, haze, and blur can be …

The light propagation model in the UDC system can be divided into following steps:
Propagation between the point source and the OLED display. The light emitted from the
point light source first hit on the front plane of the OLED display, where the optical field
UD−(p, q) can be expressed as
