Patent ID: 11948279
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 20:
21. The computing device of claim 14,
wherein the neural network is trained iteratively, and
wherein the processor is further configured to:
feed an image with a higher ISO value from a pair of training images to an input of the neural network for joint denoising and demosaicing to generate a first output image in which performed a denoising and demosaicing jointly,
process another image with a lower ISO value with the ISP algorithm, wherein the ISP algorithm including separately performing denoising and demosaicing to generate a second output image in which performed denoising and demosaicing separately,
obtain a loss function for the first output image and the second output image and obtain a gradient based on the loss function, and
update parameters of the neural network based on the obtained gradient.
