This lens supports straight out of 48 million megapixel photos via hardware-level remosaic pixel rearrangement.

By comparison, we can see that the details of the 48 million pixel mode are significantly more prominent than the standard mode. The night scene mode is limited by the amount of light entering, and it is better to control the details to restore the picture. In the second set of proofs, the building whose standard mode has been blurred is well restored in the 48 megapixel mode. The brick texture details in the third set of proofs are still stronger under the resolution of 48 million pixels. Of course, for this 48-megapixel Sony IMX586, there is room for optimization in terms of resolution and noise.
