A tentative proposal for integrated photometric system,and its application to luminous colors

A new proposal tentatively called “integrated photometric system” is given together with a detailed explanation of its structure. The proposal gives the following procedures: step 1 can determine CIE photometric quantities, step 2 can determine their perceived‐photometric correlates by applying the correction to the quantities derived in step 1. The present proposal solves the problem of coexistence of the two kinds of expected requirements in photometry suggested by Judd. In the present article, the formulas used in the step 2 are given only for luminous colors. The formulas for object colors will be given in a future article. Five applications of luminous colors are given for the step 2 of the proposed system. These applications will make it possible to promote the use of the proposed photometric system. © 2007 Wiley Periodicals, Inc. Col Res Appl, 32, 440–448, 2007
