Abstract
An image processing system includes a memory configured to store a plurality of reference images used for image quality tuning, an image signal processor configured to receive a plurality of captured images corresponding to the plurality of reference images and configured to generate a plurality of corrected images by being configured to perform a corresponding image processing operation among a plurality of image processing operations, and a tuning module configured to set parameters of the plurality of image processing operations based on the plurality of corrected images and the plurality of reference images.
Claims19
An image processing system comprising:
- a memory configured to store a plurality of reference images used for image quality tuning;
- and
- processing circuitry configured to receive a plurality of captured images corresponding to the plurality of reference images, configured to generate a plurality of corrected images by being configured to perform a corresponding image processing operation among a plurality of image processing operations, and configured to set parameters of the plurality of image processing operations based on the plurality of corrected images and the plurality of reference images,
- wherein the processing circuitry is configured to
- generate a first corrected image by performing a first image processing operation corresponding to a first reference image on a first captured image corresponding to the first reference image, and configured to set at least one first parameter of the first image processing operation based on a correlation between the first corrected image and the first reference image, the at least one first parameter corresponding to at least one of a defect pixel correction operation and an offset correction operation, and
- generate a second corrected image by performing a second image processing operation on the first corrected image and set a second parameter of the second image processing operation based on the second corrected image and a reference image, from among the plurality of reference images, corresponding to the second image processing operation.
