Noise Reduction in Multi-Aperture Cameras

Shizuoka University publishes PhD Thesis "A study on low-noise high-sensitivity multiaperture camera with selective averaging" by Bo Zhang. From the abstract: "a prototype 3×3-aperture camera is developed. Under a low-light condition, in which the maximum average signal per aperture is 11e-, the RTS noise and dark current white defects are removed and the peak signal-to-noise ratio (PSNR) of the image is increased by 6.3dB."
