Abstract:
A method includes obtaining an image, where the image includes one or more frames. The method also includes performing multi-frame processing and image signal processing on the image to produce a processed image. The method further includes performing image restoration on the processed image to produce an output image. Performing the image restoration includes generating a dither signal, applying a dither signal corner attenuation to the dither signal in order to generate an attenuated dither signal, combining the attenuated dither signal with a sharpened denoised signal in order to generate a combine signal, and applying a halo suppression on the combined signal.
