A spectral characteristic correction device for correcting a spectral characteristic characterizing a color signal composed of a plurality of chrominance signals.
A method for preparing a speech signal for encoding comprises determining whether the spectral content of an input speech signal is representative of a defined spectral characteristic (e.g., a defined characteristic slope).
This optical module can effectively and rapidly measure a spectral characteristic of an object to be observed.
Further, the microcontroller provides tunability of the spectral characteristic and intensity of the white luminaire.
There are exclusively used the two colours "red violet" and "green" which present a well defined spectral characteristic.
A first group is disposed in frequency at the spectral feature of interest and serves to probe the spectral feature.
At least one spectral feature vector is computed for each frame.
The method also includes tracking the spectral parameters of the at least one spectral feature over time.
The CML adopted in the optical module of ONU has better spectrum characteristic, accordingly reducing channel interval and achieving the purposes of supplying more uplink channels and increasing system bandwidth.
The spectral characteristic of the illuminating light passing through the exciting light filter (24) and the transmittance characteristic of the excitation cut filter (11) have an overlap region.
Within each group the component sidebands are offset from one another by a characteristic offset frequency, which can be considerably less than the width of the spectral feature under investigation.
When using a spectral endoscope, it is possible to set a spectral characteristic appropriate for the use condition.
An imaging system estimates an unknown spectrum feature concerning an object or an illumination light according to video signals from a color imaging system.
The backlight luminaire (50) is employed in liquid-crystal display devices (51) in order to attain a light distribution having a uniform spectral characteristic.
A backlight luminaire (50) is provided with at least two tubular fluorescent lamps (44, 45), with portions of the lamps (44, 45) exhibiting a variation in spectral characteristic in the longitudinal direction.
The determination of the spectral characteristic could be done without using any measurement of light that has not interacted with the sample (106, 206, 306, 606, 706).
Each phosphor is of a type or configuration that when excited by energy in the 380-420 nm range, emits light of a different spectral characteristic.
The measurement could be used by an analyzer (112, 212, 312, 612, 712) to determine a spectral characteristic (such as a color) of the sample (106, 206, 306, 606, 706).
Accordingly, it is possible to change the light transmittance (reflectance) without changing the spectral characteristic or the RGB ratio of the incident light.
In this incorporated form, the photophysical characteristics of the dyes (spectral characteristic, luminescence quantum efficiency, luminescence fading time and polarization) remain unaffected by sample parameters that vary.
