Abstract: An image sensing device including an image sensor configured to output a raw image by capturing an image of a subject and an image signal processor configured to perform a bad pixel correction process on the raw image on an image patch-by-image patch unit, compare pixels of an image patch of the raw image with a local saturation threshold value, determine a state of local saturation of the image patch based on a number of saturated pixels whose pixel values exceed the local saturation threshold value, and output a corrected image patch, which is obtained by correcting a pixel of the image patch with a corrected pixel value, with a replacement pixel value, or with a raw pixel value depending on the state of local saturation of the image patch.

Abstract: A system on chip and method for operating a system on chip are provided. A system on chip includes a shared memory configured to store image data and a processor configured to: generate a first correction value by performing first image processing for a first pixel value of a first pixel of the image data received from the shared memory, generate a second correction value by performing second image processing, which is different from the first image processing, for the first pixel value of the image data received from the shared memory, generate a third correction value by performing third image processing, which is different from the first image processing and the second image processing, for the first pixel value of the image data received from the shared memory, and output a first pixel correction value that is changed from the first pixel value by comparing the first to third correction values with the first pixel value and selecting one of the first to third correction values.
