Halogen Lighting
| A type of incandescent lamp containing a small amount of halogen | HDR Mode
| HDR = high dynamic range | HID
| High-intensity discharge lamps | High dynamic range | In the high dynamic range mode various nonlinearity points, the so-called
knee-points (and integration time as a second parameter) can be freely
adjusted, leading to increased dynamic range. This enables the high
dynamic range of the sensor to be compressed into 8 bit, preserving
interesting details of the image. This mode is also known as multiple
slope. | Histogram | Displays the total number of pixels in each grayscale value. From the
histogram, you can discern if the image contains distinct regions of a
certain grayscale value, and you can select grayscale pixel regions of
the image by sliding the white and black | Horizontal binning | In horizontal binning adjacent horizontal pixels in a line are combined
in pairs. This means that in horizontal binning the light sensitivity of
the camera is also increased by a factor of two (6 dB). Signal-to-noise
separation improves by approx. 3 dB. Horizontal resolution is lowered,
depending on the model. See also: vertical binning and full binning | Host computer | Host computer is the primary or controlling computer for a digital camera. | HSV Color Space
| The HSV (hue, saturation, value) model, also called HSB (hue,
saturation, brightness), defines a color space in terms of three
constituent components: • Hue, the color type (such as red, blue, or
yellow). • Saturation, the vibrancy of the color and colorimetric
purity. • Value, the brightness of the color | Hue | A hue refers to the gradation of color within the optical spectrum, or
visible spectrum, of light. Hue may also refer to a particular color
within this spectrum, as defined by its dominant wavelength, or the
central tendency of its combined wavelengths. For example, a light wave
with a central tendency within 565-590 nm will be yellow. In an RGB
color space, hue can be thought of as an angle P in standard position.
The other coordinates are saturation and brightness. |
