Übersetzung für "Helligkeitsmessung" in Englisch

Lux is a unit for measuring brightness.

The color and lightness measurement can be carried out with conventional color measuring devices.

The color and lightness measurement is preferably carried out with an online color measuring device.

This is possible thanks to thePrema's integrated, calibratable brightness measurement function.

Every master controls its lighting group according to its own brightness measurements.

We disabled the ambient light sensor via FN+F11 for the measurements.

The brightness measurement can be calibrated automatically by entering the measured lux value.

Turn off a black brightness measurement from the calculation of gamma, to minimize error.

In this manner, the additional information ZI is recovered by measurement of brightness and introduced in digital form into a second register 24.

If this is the case, in an additional interrogation step (21) an interrogation is conducted to determine whether a brightness measurement performed with controllable switch (6) open produces undershooting of the preset brightness limit.

Up to five standard sensors for air pressure measurements, temperature monitoring, humidity sensing, light level measurement and acceleration/motion detection are internally available with the MSR145.

After controlling the LEDs with the new dimming factors, an anew brightness measurement is effected for detecting the actual value Y Ist individually for each LED color group with the aid of the light sensor or V(?) sensor.

Thus, detection of the brightness can be performed especially efficiently, wherein the brightness measurement can be realized even in strongly brightened states/areas, as merely the exposure time has to be adapted.

Thus, it is also useful when an exposure time value of the camera is or can be fixedly set, which equally allows implementation of a brightness measurement to be more efficient.

In an advantageous variant the brightness measurement is performed multiple times in order to detect and/or compensate for fluctuations as they occur, for instance, due to periodic or steady physiological changes.

Samples of the sink units are soiled with and without abrasive pretreatment (see above) and then cleaned under defined conditions (see above), and the residual soil remaining on the surface is determined by photoelectric photometry. Residual soil without abrasive pretreatment:

Samples of the sink units are soiled with a synthetic model dirt batch with and without abrasive pretreatment, and the residual soil on the surface is determined by photoelectric photometry.

Panels of pure PTFE (Hostaflon, sold by Dyneon, Germany) are soiled with a synthetic model dirt batch with and without abrasive pretreatment and cleaned under defined conditions and the residual soil remaining on the surface is determined by photoelectric photometry.

Following addition of the peroxides (40 g of Peroxan BCC and 80 g of Peroxan LP in each case sold by Pergan, Germany), thermal curing of the molding composition is carried out in suitable (kitchen sink unit) molds in a manner similar to that described in Example 1. Samples of the sink units are soiled with a synthetic model dirt batch with and without abrasive pretreatment, and the residual soil on the surface is determined by photoelectric photometry.

An optical device according to claim 6, wherein the control signal of the diameter of the pupil can be obtained by a sensor designed to detect the movement of the iris muscle (71), and the luminance can be determined by a photodiode (74) designed to measure the brightness.
