What They Say
Scientists from Peking University recognised that one of the limits on digital photography resolution, along with ccd pixel size, is that lenses are circular, while sensors are all rectangular. Sampling usually takes place in the horizontal or vertical direction The group found, after data analysis from different angles, that they can collect up to 1.4 times more pixels by sampling diagonally.
What We Think
The article describes this as a ‘Columbus egg’ problem – which led me down a rabbit hole. It means a problem the solution to which is obvious once it has been seen, but not before. The research group sees applications in telescope imaging, machine vision and spectroscopy. I wonder looking at things diagonally could improve image scaling? (BR)
