Fig. 4: Super-resolution imaging by array images.
From: Biologically inspired ultrathin arrayed camera for high-contrast and high-resolution imaging
a “Dice” array images captured by the ultrathin arrayed camera. The “dice” test image was displayed on an LED panel at the far-field plane to observe the same figure in each channel. b Image reconstructions according to the number of array images by super-resolution imaging. c MTF50 graph for the number of merged images. The calculated results show that the combination of array images enhances the image resolution. d The captured array images of a red parrot to measure the colour differences between a target object and acquired images. e An image captured by a single channel of the ultrathin camera before image reconstruction. f A reconstructed image by super-resolution imaging. Photographs of g a commercialised compact camera (Raspberry pi camera V2) and h the ultrathin arrayed camera. Radial star images acquired by i the commercialised camera and j the single channel of the ultrathin arrayed camera. k Reconstructed image from several channels. l Comparison of MTF curves measured by the commercialised compact camera image, the single channel image of ultrathin arrayed camera, and the reconstructed image
