Introduction
This guidance document covers the latest protocols for 10 types of metering systems (4 for a 2 ° field of view and 6 for a 10 ° field of view), which
These programs were submitted to Division 1 of the International Commission on Illumination (CIE) as a light-to-light relative to all ranges of human visual acuity
Brightness determination method. In order to quantitatively test these systems, a number of applications submitted by independent laboratories for different color brightness
Assay (HCBM) Data sets obtained using different stimulation combinations and experimental procedures. Also, six research groups are using the same color
Color samples were tested on each system using the data obtained from HCBM experiments under very similar conditions. These numerical tests are mainly
Instead of testing the absolute level of the brightness metric, in order to test the equality of the equivalent brightness of the brightness-matching stimulus. This instructional technical article
Describe the results of these quantitative tests and make no recommendations regarding the new CIE system.
Photometric aided measurement system
1 General
The current metering brightness, as defined by the CIE metering system, is not sufficiently correlated with the perceived brightness of colored objects or light sources.
The difference between brightness and brightness, itself manifested as a superposition missing problem; the superposition of two or more monochromatic light source table
Viewing brightness often differs from the sum of their brightness. In the bright vision, the superposition effect is usually less than the sum of brightness, then addability missing
Loss mainly in the sub-additivity. The current color theory accounts for this phenomenon based on the interaction between human eye cones
Helmholtz-Kohlrausch); the saturated color gives a "color contribution" to the physiological brightness signal.
Strong overdisappearances can also occur, in which case the effect of two or more monochromatic light sources superimposing is much greater than their brightness
Overlay effect. Since this phenomenon often occurs at intermediate visual levels, it is inferred that it is the interaction between the human eye's cones - the human eye's rod cells
The result of the action. Spectral sensitivity changes from human eye cones to human eye rod cells, accompanied by a reduction in apparent brightness,
In terms of shades of light, the brightness of blue light is enhanced. In dark vision, this purkinjeshift is complete, because
Here, the phenomenon of overlay loss tends to disappear.
Recognizing these differences in brightness and brightness, Division 1 of CIE has appointed several technical committees in the past 15 years
Will investigate the issue of Heterochromatic Brightness Matching (HCBM) and work hard to develop a new type of metering system for measuring brightness. The earliest
Several technical committees are shown below.
TC1-01 Intermediate Visual Photometry (by JAS Kinney)
TC1-02 luminous efficiency function (by M. Ikeda)
TC1-03 Heterogeneous luminance matching model (by PKKaiser)
TC1-01 provides an excellent summary of intermediate vision photometry systems that have emerged since the late 1980s
Ming Committee, 1989) laid the foundation for TC1-21. The TC1-02 is built for point light sources at 2 ° and 10 ° field-of-view, depending on the brightness of the light
Degree of spectral luminous efficiency function (International Commission on Illumination, 1988). These luminous efficiency functions can not only be used as a photometric reference data,
But also provides reference data for the further study of different color brightness matching test. TC1-03 investigated and studied the brightness matching test
Physiological model of the trial (International Commission on Illumination, 1986).
In response to these technical committee initiatives, some research groups have proposed photometric system solutions based on different color brightness matching tests.
Taking into account the future development of international standards, the standard required to provide a satisfactory, suitable for all brightness levels of brightness measurement
Volume 1, Division 1 evaluated these systems.
TC1-21, Testing of Auxiliary Metering Systems, at the 21st Annual International Lighting Convention, Venice, 1987
Set up The technical committee directly quantified the system by using the proposed system for data from HCBM experiments
test. Its mission is to report how well the system predicts these data. However, its terms of reference will not extend to recommending any one
System as an international lighting standard.
The current report provides numerical data and procedures for testing. Considering the predictability of the relationship between the brightness of colored objects or light sources is
One of the main functions of photometric measurement, the current test is designed to be used for each proposed system to verify that its description is from the HCBM test
The brightness of the test match the brightness of the same degree of the pros and cons.
Chapter 1 points out the problems with the current lighting system of the International Commission on Illumination and the setting of TC1-21 to solve these problems
aims. Chapter 2 outlines the currently proposed HCBM-based metering system, updated TC1-01 report (International Lighting Commission
Yes, 1989) and added some recently proposed systems. For each system, this chapter provides a calculation for "system equivalent brightness"
As well as a computational example, "System Equivalent Luminance" is used as a measure of apparent brightness for a particular reference stimulus. Chapter 3 describes it
System testing selected data sets and testing process. Chapter 4 reports on the application of the proposed metering system to these data sets
System equivalent brightness. Chapter 5 reports on the quantitative results obtained using these systems on a new dataset from
Tests carried out in six laboratories in four different countries under general stimulation and general test conditions are those of TC1-21 for.1991
