System and method to improve quality in under-display camera system with radially increasing distortion

A system and method are provided to improve quality in an under-display camera (UDC) system with radially-increasing distortion. At least one processor receives an image and performs multi-frame processing, image signal processing, and a point spread function inversion (PSFI) on the image to produce a processed image. A PSFI radial coring is applied on the processed image to reduce noise in the processed image resulting from the PSFI. The at least one processor can apply a chroma suppression to the processing of the image to reduce brightness and color saturation is select areas in the processed image. Image restoration can be performed on the processed image to produce an output image. The image restoration may include generating a dither signal, applying a dither signal corner attenuation to the dither signal, combining the attenuated dither signal with a sharpened denoised signal, and applying a halo suppression on the combined signals.
