System on chip and method for operating system on chip

A method for operating a system on chip, the method comprising:

• generating a first correction value by performing first image processing for a first pixel value of a first pixel of first image data provided from a shared memory;
• generating a second correction value by performing second image processing, which is different from the first image processing, for the first pixel value of the first image data provided from the shared memory;
• generating 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 first image data provided from the shared memory;
• outputting 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;
• generating a fourth correction value by performing the first image processing for a second pixel value of a second pixel of second image data that is different from the first image data and provided from the shared memory;
• generating a fifth correction value by performing the second image processing, which is different from the first image processing, for the second pixel value of the second image data provided from the shared memory;
• generating a sixth correction value by performing the third image processing, which is different from the first image processing and the second image processing, for the second pixel value of the second image data provided from the shared memory;
• and
• outputting a second pixel correction value that is changed from the second pixel value by comparing the fourth to sixth correction values with the second pixel value and selecting one of the fourth to sixth correction values.
