Snippet: Samsung ‘Fake’ Moon Shots Controversy Puts Computational Photography in the Spotlight ☇

Shared on March 13, 2023

Hartley Charlton for MacRumors:

Samsung introduced a 100x zoom feature with the Galaxy S20 Ultra in 2020, becoming a mainstay on recent flagship handsets from the company. Since its debut, Samsung has touted its devices’ ability to take impressive pictures of the moon. Unlike brands such as Huawei, which simply overlay a PNG of the moon on such images, Samsung says that no overlays or texture effects are applied.

Yet on Friday, a Samsung user on the subreddit r/Android shared a detailed post purporting to “prove” that Samsung’s moon shots are “fake.” Their methodology involved downloading a high-resolution image of the moon, downsizing it to just 170 by 170 pixels, clipping the highlights, and applying a gaussian blur to heavily obscure the moon’s surface details. This low-resolution image was then displayed on a monitor and captured at a distance from a Samsung Galaxy device. The resulting image has considerably more detail than its source.

I’d be interested to see more tests to prove/disprove how computational photography might be “eager” to help.
