Abstract
An image processing unit includes an imaging sensor having a pixel array, a memory storing an artificial neural network (ANN), and an image signal processor configured to operate the ANN on an image output by the imaging sensor to predict an error value of a pixel of the image and correct the pixel using the predicted error value.
Claims22
An image processing unit, comprising:
- an image sensor comprising a pixel array;
- a memory storing an artificial neural network (ANN);
- and
- an image signal processor configured to operate the ANN on an image output by the image sensor to predict an error value of a pixel of the image and correct the pixel using the predicted error value.
1 more element
A method for correcting an image captured by an imaging sensor, comprising:
- training, by a processor, an artificial neural network (ANN) to predict an error value of a pixel of an image using a training patch of a training image;
- operating, by the processor, the ANN on a new image output by the imaging sensor to determine error values of the new image;
- and
- correcting, by the processor, the new image using the determined error values.

An image signal processing unit, comprising:
- an image signal processing unit configured to train an artificial neural network (ANN) on patches of flat-field images and patches of read-world images to predict an error value in a pixel of an image, operate the trained ANN on an input image to output error values, and correct the input image using the error values.
