How it Works

To accurately generate a LUT, you must work from a calibrated and characterized display. A sensor, which you position on your display, measures the luminance and chromaticities of a series of color patches. You can also use the sensor to verify the calibration and characterization.

NOTE

To characterize a projector you must use a spectrophotometer or a colorimeter suitable for measuring screen reflectance.

Calibration

The automatic calibration process gathers information from a sensor and transfers it to the monitor via the enable cable (USB Cable ECC 1). Adjustments are automatically made to the monitor contrast, brightness, and individual RGB biases and gains via the enable cable, based on information gathered by the sensor.

The first time that you initiate automatic calibration, the system prompts you to perform a monitor evaluation to determine if your monitor is capable of being automatically calibrated.

When calibrating an HD/SD device, you must manually calibrate the device using standard SMPTE procedures. A colorbars target is supplied with the Display Manager System.

Manually calibrate your display to SMPTE standards if:

•You are using an IRIX system

•You have an HD/SD device

•The enable cable does not recognize your monitor

•You were unable to successfully calibrate your monitor using automatic calibration

Characterization

After you have calibrated your display, you must characterize it to determine the gamma response and to track the primaries. The result is a .chr file, which the system uses to create a LUT.

HD/SD displays and digital projectors must be characterized using the Manual Characterization Assistant. When characterizing these displays, you can:

•project display patches (provided on the Display Manager System CD or downloaded from http://www.kodak.com/US/en/motion/products/ dlmanage/kdmDown.jhtml) through a supported imaging application

•display patches from one of the KODAK Color Patch Set video tapes available from Kodak
