Abstract
According to an embodiment of the present inventive concept, an image sensor includes a sensor including a plurality of pixels and configured to capture incident light and generate raw image data; a pre-processing processor configured to generate first image data by applying a first function to the raw image data; an image processor configured to receive the first image data and generate second image data using a machine learning model; and a post-processing processor configured to generate third image data by applying a second function to the second image data, wherein the first function is a non-linear function.
Claims20
An image sensor comprising:
- a sensor including a plurality of pixels and configured to capture incident light and generate raw image data;
- a pre-processing processor configured to generate first image data by applying a first function to the raw image data;
- an image processor configured to receive the first image data and generate second image data using a machine learning model;
- and
- a post-processing processor configured to generate third image data by applying a second function to the second image data,
- wherein the first function is a non-linear function, and, when applied to the raw image data, amplifies luminance in low-luminance portions of the raw image data, and reduces luminance in high-luminance portions of the raw image data.
An image processing system comprising:
- an image sensor including a plurality of pixels;
- a pre-processing processor configured to generate first image data by applying a first function to raw image data generated from the plurality of pixels,
- an image processor configured to receive the first image data and generate second image data by applying a machine learning model to the first image data, and
- a post-processing processor configured to generate third image data by applying a second function to the second image data;
- and
- an image signal processor configured to receive the third image data as input image data and generate output image data by applying a third function to the input image data,
- wherein the third function is a non-linear function.
An image processing system comprising:
- an image sensor including a pre-processing processor configured to generate first image data by applying a first function to raw image data generated from a plurality of pixels,
- an image processor configured to receive the first image data and generate second image data by applying a deep learning model to the first image data, and
- a post-processing processor configured to generate third image data by applying a second function to the second image data;
- and
- an image signal processor configured to receive the third image data as input image data and generate output image data by applying a third function to the input image data,
- wherein the first function, the second function, and the third function are non-linear functions.
