Few decades ago, approach to character recognition was limited to desktop scanner. The usability of such system was limited as they were non portable because of large size. With the advent of technology and portable computing devices such as mobile phone, PDA, iPhone etc. new trends of research has emerged, where Mobile phones are the most commonly used electronic device, eliminating the need for bulky devices like scanners, desktops and laptops. The convergence of powerful processors and high resolution cameras on mobile devices has directed the focus of research to development of mobile applications, where image processing applications such as OCR’s are in demand. This paper present State-of-the-Art survey of Character Recognition systems for mobile devices and summarize some commercially available OCR applications.
