Abstract:	在當前科技迅速發展的背景下，數位相機的解析度仍然受限於感測器尺寸和像素密度，導致在影像解析度方面面臨諸多挑戰。本論文的宗旨在深入探討如何通過像素位移技術，突破這些傳統技術的侷限，實現數位相機影像解析度的提升，我們通過模擬相機進行隨機位移來拍攝物體，得到多張低解析度的照片後，合成一張高解析度的照片，透過一維和二維模擬結果，能夠明顯看出提升影像解析度，最後將此結果與市面上常見的影像內插法進行比較，展示像素位移技術在提升解析度方面的優勢，並證明此方法在影像解析度方面有著顯著的提升。;In the context of rapidly advancing technology, the resolution of digital cameras remains constrained by sensor size and pixel density, leading to numerous challenges in image resolution. This paper aims to explore how pixel shift technology can overcome these traditional limitations and enhance the resolution of digital camera images. By simulating random camera displacements to capture an object, multiple low-resolution photos are obtained and then synthesized into a high-resolution image. Through one-dimensional and two dimensional simulation results, a significant improvement in image resolution can be observed. Finally, the results are compared with common interpolation methods available on the market, demonstrating the advantages of pixel shift technology in enhancing resolution and proving its effectiveness in significantly improving image resolution.
