74‐1: Image Restoration for Display‐Integrated Camera

Under‐display camera is of great interest in the display industry potentially eliminating the display bezel and camera notch/hole in mobile devices. However, display panels cause complex signal modulation in the camera aperture which results in obscuration, attenuation and diffraction of the inciden...

Zusammenfassung:	Under‐display camera is of great interest in the display industry potentially eliminating the display bezel and camera notch/hole in mobile devices. However, display panels cause complex signal modulation in the camera aperture which results in obscuration, attenuation and diffraction of the incident light. We propose a learning‐based image restoration approach to enable a camera to operate underneath the display without affecting the display contrast and color gamut.
