1. A circuit, comprising:
a threshold circuit configured to:
receive a block of pixels corresponding to a first location of an image in a raw image format, wherein the block of pixels comprises a plurality of mosaiced color channels, and
for each pixel of the block of pixels, compare a value of the pixel of the block of pixels with a threshold value corresponding to a mosaiced color channel of the plurality of mosaiced color channels to generate a comparison result; and
a logic circuit coupled to the threshold circuit, and configured to generate light information by processing the comparison result generated for each pixel of the block of pixels, the light information indicating whether an artifact is likely to be present at a second location of the image that is diagonally opposite to the first location relative to an optical center of an image sensor that captured the image.
