SYSTEM AND METHOD TO IMPROVE QUALITY IN UNDER-DISPLAY CAMERA SYSTEM WITH RADIALLY-INCREASING DISTORTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18354409 titled 'SYSTEM AND METHOD TO IMPROVE QUALITY IN UNDER-DISPLAY CAMERA SYSTEM WITH RADIALLY-INCREASING DISTORTION
Simplified Explanation
The patent application describes a method for processing images to improve their quality and reduce noise.
- Obtaining an image with one or more frames.
- Performing multi-frame processing and image signal processing on the image to enhance its quality.
- Performing image restoration on the processed image to further improve its quality.
- Generating a dither signal and applying a corner attenuation to it to reduce noise in the image.
- Combining the attenuated dither signal with a sharpened denoised signal to create a combined signal.
- Applying halo suppression on the combined signal to reduce artifacts in the image.
Original Abstract Submitted
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.
