Quantitative Comparison of Commercial CCD and Custom-Designed CMOS Camera for Biological Applications

Giovanni De Micheli, Sandro Carrara, René Beuchat, Yusuf Leblebici, Gözen Köklü, Julien Michel Ghaye

In biological applications and systems where even the smallest details have a meaning, CCD cameras are mostly preferred and they hold most of the market share despite their high costs. In this paper, we propose a custom-designed CMOS camera to compete with ...
