True-color and super-resolution imaging using an optical axis shiftable liquid crystal lens

This study explores the utilization of a liquid crystal lens with a shiftable axis for true-color and super-resolution imaging. By maintaining the optical power and shifting the axis of the liquid crystal lens, precise sub-pixel level shifts are applied to the images formed on the sensor, enabling the construction of true-color and super-resolution images. A comparative analysis with the traditional interpolation-based demosaicing method reveals that true-color imaging not only enhances clarity and effective pixel count, but also significantly reduces occurrences of false color, edge aliasing, and color moiré artifacts.
