Abstract:
Smartphones appeared on the market only a decade ago. However, the market has since grown rapidly, and people of all ages now use smartphones. In many cases, people read text on their smartphones, but depending on the design of a website, it may be difficult to read its text. By improving the resolution of the text, the readability of text can be improved. One research area for increasing the resolution is super resolution (SR), which includes nonlinear signal processing super- resolution SR (NLSP), a method that can be implemented on smartphones. However, NLSP has never been applied to text in order to improve readability. We applied NLSP for text displayed on liquid crystal display (LCD), and verified its effectiveness. Thus, in this paper, the assessment results for text on LCD are discussed.
