In the last two decades multimedia, and in particular imaging devices (camcorders, tablets, mobile phones, etc.) have been dramatically diffused. Moreover the increasing of their computational performances, combined with an higher storage capability, allows them to process large amount of data. In this paper an overview of the current trends of consumer cameras market and technology will be given, providing also some details about the recent past (from Digital Still Camera up today) and forthcoming key issues.
Computational Aesthetics applied on digital photography is becoming an interesting issue in different frameworks
(e.g., photo album summarization, imaging acquisition devices). Although it is widely believed and can often be
experimentally demonstrated that aesthetics is mainly subjective, we aim to find some formal or mathematical
explanations of aesthetics in photographs. We propose a scoring function to give an aesthetic evaluation of
digital portraits and group pictures, taking into account faces aspect ratio, their perceptual goodness in terms
of lighting of the skin and their position. Also well-known composition rules (e.g., rule of thirds) are considered
especially for single portrait. Both subjective and quantitatively experiments have confirmed the effectiveness of
the proposed methodology.
