To understand the novel approach taken by the Canon optical designers to seek this particular aspect of a cine lens personality the simple illustration of Figure 5 should help set the stage. This shows a simple scene comprising a high and sharp brightness transition – between black barsand adjacent white bars.

CINEMA EOS LENSES

Studying how each of these lenses convoluted with the Canon CMOS image sensor and allied Canon CFA helped establish overall color reproduction benchmarks that guided the subsequent exploration of the new Canon cinema lens spectral response. Video processing – in the form of the digital linear matricing system – was also optimized. The judgment of color balance was made by Canon color scientists in concert with invited directors of photography studying the simulated imagery.

Upon confronting the term Modulation Transfer Function, the question immediately arises as to what is being modulated, what is being transferred, and how does all of this bear upon resolution? It will be shown that these terms help us provide a linkage between the resolution capability of an imaging component and the contribution that component makes to the perceived sharpness seen when we look at the final reproduced image.
