Active Technical Committees
TC1-30 (V) Luminous Efficiency Functions
Year Established: 1990
Terms of Reference:
To prepare a Technical Report on luminous efficiency functions which classifies and specifies
the existing functions Vb,point(λ), V(λ), Vb,2(λ), VM(λ) and Vb,10(λ), and the color matching
function y - 10(λ) if appropriate, in their photometric use.
Chairman: Y Nakano JP
Members: M Ikeda JP, P K Kaiser CA, JA Kinney US, S Kokoschka DE, P Trezona GB, K
Sagawa JP, H Yaguchi JP, F Viénot FR
Report:
This committee was closed at the Beijing meeting of 2007 with the work being transferred to a
new reportership, R1-45.
TC1-36 (V) Fundamental Chromaticity Diagram with Physiologically
Significant Axes
Year Established: 1991
Terms of Reference:
To establish a chromaticity diagram of which the coordinates correspond to physiologically
significant axes.
Chairman: F Viénot FR
Members: D MacLeod US, JD Mollon GB, JD Moreland GB, Y Nakano JP, J Pokorny US,
LT Sharpe DE, A Stockman US, A Valberg NO, PL Walraven NL, J Wold NO
Consultants: H Scheibner DE, P Trezona GB, and H Yaguchi JP
Working Program:
Write a report with a clear statement on the choice of a set of color-matching functions and
estimates of cone fundamentals for the normal observer. The committee will take into account the
variability among normal and dichromatic observers.
1. Agreement should be reached on the following points:
a. Choice of a set of color-matching functions and evaluation of the consequence of this
choice, compared to other possibilities.
b. Accordance with the 1988 VM(λ) luminous efficiency function.
