|Revamped Subcommittee on Image Based Color Measurement Launching Two New Standards Activities |
Subcommittee E12.06, part of ASTM Committee E12 on Color and Appearance, has undergone a change of both its title and its scope. The subcommittee, which was previously known as Appearance of Displays, is now Subcommittee E12.06 on Image Based Color Measurement. The new scope of the subcommittee is to create standards that prescribe the measurement characterization, calibration and methodologies of digital color devices such as: displays, digital cameras, monitors, scanners, printers, projectors, and machine vision systems.
The scope is being changed to encompass the changes in the broadening technology of digital imaging, says Jack Ladson, president and CEO of Color Science Consultancy and chair of E12.06. While color has been measured during the last 50 years using instruments such as spectrophotometers and colorimeters, Ladson says that digital imaging technology is creating different opportunities and needs for the quantification and measurement of color and color appearance phenomena.
While the standards that had previously been under the jurisdiction of E12.06 will remain, the subcommittee is also beginning work on two new standards, one on digital camera colorimetry and one on digital camera colorimetry for the measurement of teeth. Ladson says the new standards are being developed because there are currently no standards that prescribe methods for the measurement of color and color appearance using digital technology. With the role that ASTM plays in the international standardization community, says Ladson, the development of standards, methodologies and tools for these devices is of utmost importance.

E12 meets May 17-19 at the National Institute of Standards and Technology, Gaithersburg, Md. For membership or meeting details, contact Kevin Shanahan, ASTM International (phone: 610/832-9737). //
