Abstract:

Increasing pixel resolutions on displays are a current trend of consumer products. Lower resolution images can be input to these kinds of products. In this case, we have to enlarge the input images. Usually, large scale integration (LSI) and an application specified chip (ASIC) for consumer products enlarge input images by linear processes. However a linear process cannot generate a higher frequency component than the Nyquist Frequency of the input image and outputs a blurred image. In this paper, we present an image enlargement method that generates the higher frequency component and is suitable for hardware implementation.
