隨著科技的進步,影像感測器已不像之前那樣有著體積較大、像素較差、影像品質不夠清晰等缺點,現在不論是尺寸、規格、品質都已有很大的進步,並且也開始大量運用在許多各視各樣的產品上,例如手機及平板電腦的相機、保全相關之監視設備、互動式玩具,甚至連觸控式螢幕等等。本文旨在設計規劃整個系統並利用影像感測器來擷取影像,再針對所擷取影像的品質加以提升,最後使其能轉換成文字並提高辨識率。
With the advances in technology, the image sensor has been unlike before and no longer having the shortcomings of large dimension, low resolution and etc. Now there has been great improvement on quality, dimension and specification in image sensor which would be used of various as kinds of products such as the cameras on mobile phones and tablet PCs, surveillance systems, interactive toys, and even touch screens. This article aims to design and plan the entire system by taking advantage of image captured via image sensor for further processing and then finally be converted into text.
