Digital still cameras (DSCs) are overtaking conventional film cameras in popularity, ease of use, and level of performance. Nakamura, an engineering scientist with a major Japanese digital technology company, introduces 11 chapters focusing on the optical system design process and other technical facets of DSCs. Japanese and US contributors treat issues in image sensor functions and evaluation, reducing signaling noise, and other technical challenges. The last chapter treats future directions in this technology, e.g., high-end digital SLR cameras, HDTV-compatible movie modes, and personal continuously recording devices. Color and b&w images illustrate aspects of resolution and other image variables. Appendices provide further technical details. Annotation ©2005 Book News, Inc., Portland, OR (booknews.com)
