The Admesy Hyperion & Prometheus colourimeters work in combination with ColourSpace to enable accurate calibration to be achieved for both projection as well as monitors, with a large range of lens options, etc.
- ColourSpace INF/XPT/PRO & HTX/HTP
As with all probes, operation and function is controlled via the Probe Options menu, accessed via the Profiling window, with the left-hand side of the menu providing generic probes settings, and the right-hand side settings specific to the Admesy colourimeters.
Admesy Colourimeter Settings
The Settings options provide specific Admesy colourimeter configurations. Full details for all options can be found within Admesy's own documentation.
Note: ColourSpace only uses colourimeter mode, as Flicker, Response Time, etc., are not valid for display calibration.
Integration Time sets the maximum time taken for any given single measurement, in micro-seconds.
The default setting is as shown, although different values will likely be required depending on the display being profiled, with longer values generating more accurate and stable readings.
Num. To Average
The number of readings to average over.
The drop-down sets the probe sensitivity, with Low(1) being most sensitive.
The drop-down menu provides access to any pre-set matrices held within the Admesy probe.
The Matrix presets match the probe to different display technologies - specifically the backlight/illumination spectral response.
The Drop-down menu sets Auto Range to Off or On.
See Auto Range Parameters
Note: Intelligent Integration is disabled when Auto Range is set to On.
The Drop-down menu sets Auto Mode to Fast, Normal, Slow, Hi-Sensitivity, or Manual.
The Drop-down menu sets Dark Mode to Off or On.
Auto Range Parameters
Manually setting probe values can be complex as the optimal settings depend on the luminance of the screen being measured. The Auto Range function can be used to define optimum settings during measurement, and can be fine-tuned for better stability levels by manually setting parameters the available parameters.
Frame Frequency (Hz)
The frame rate of the display being measured, in the range 1 to 255 Hz.
The minimum level to adjust to, based on the scale of the ADC expressed in %. The higher this level is set, the more stable the measurement, as well as being slower.
Sets the number of frames to measurer during Auto Range configuration.
Max Int. Time
Sets a clip point beyond which integration will cease to operate, to prevent excessively long readings.
Used for real readings after the Auto Range has been automatically defined, setting the the number of readings to average.
Intelligent Integration sets the nits level under which Intelligent Integration will be used.
This provides the best possible low-light measurements, without impacting reading speeds at luma levels above the set value, so maintaining overall speed of profiling.
Average Low Light
Average Low Light is a probe generic option, that averages multiple readings in low-light situations using an advanced algorithm built into ColourSpace. The algorithm varies based on the probe in use to provide the best possible results.
Average Low Light should not need to be used when Intelligent Integration is active.
Probe Adjustments are generic probes settings, with consistent operation regardless of the probe in use.
Probe Matching is used to match a Tristimulus to a Spectroradiometer, increasing the profile accuracy.
There are three different methods available for probe matching - ColourSpace's unique 4 Colour Volumetric Matching (FCVM), and Multi-point Volumetric Matching (MPVM), with the option to force the use of the traditional simple matrix method (FCMM).
Probe Offset enables a user to manually enter offset values for different probes/display combinations.
Perceptual Colour Match is a preferable approach.
Extra Delay sets a delay time after the patch has changed before probe measurement starts, and can be set automatically via the Auto button, and manages signal path delays in the image pipeline.
When using the Auto option, Average Low Light should not be enabled.
