Resource Overview

Using simulation to acquire four low-resolution images with half-pixel mutual offsets, and reconstructing a high-resolution image through inverse analytical algorithms - categorized as sub-pixel or super-resolution technology. The implementation typically involves pixel shifting simulations and iterative reconstruction algorithms to enhance image resolution beyond sensor limitations.

Detailed Documentation

This document discusses a methodology known as sub-pixel technology or super-resolution technology. The approach involves generating four simulated low-resolution images with mutual half-pixel offsets through controlled pixel shifting operations. These images are then processed using inverse analytical reconstruction algorithms, such as maximum likelihood estimation or iterative back-projection methods, to synthesize a single high-resolution image. The core technical implementation typically includes pixel registration, interpolation optimization, and frequency domain transformation to enhance image clarity and detail resolution. The primary objective of this technology is to improve image sharpness and visual detail through advanced image processing algorithms, ultimately achieving superior visual quality that exceeds the native resolution capabilities of the imaging system.
