In this paper, we present a system for enhancing digital photography on mobile displays. The system is using adaptive filtering and display specific methods for maximizing the subjective quality of images. Because mobile platforms have a limited amount of memory and processing power, we describe computationally efficient scaling and enhancement algorithms that are especially suitable for mobile devices and displays. We also show how a proper arrangement of these algorithms forms an image processing chain that is optimized for mobile use.
The developed image enhancement system has been implemented using the Nokia Series60 platform and tested on imaging phones. Tests and results show that significant improvement of quality can be achieved with this solution within the processing power and memory limitations that mobile platforms set.
