reset
The leakage of charge from a saturated pixel into neighboring pixels.
A constant that converts the number of electrons collected by a pixel into digital output (in DN). It can be
extracted from photon transfer curves.
Variation of column mean signal strengths. The human eye is sensitive to line patterns so this noise is
analyzed separately.
A constant that converts the number of electrons collected by a pixel into the voltage swing of the pixel.
Conversion gain = q/C where q is the charge of an electron (1.602E 19 Coulomb) and C is the capacitance
of the photodiode or sense node.
Correlated double sampling. This is a method for sampling a pixel where the pixel voltage after reset is
sampled and subtracted from the voltage after exposure to light.
Color filter array. The materials deposited on top of pixels that selectively transmit color.
The leakage of signal from one color channel into another when the imager is NOT saturated. The signal
can leak through either optical means, in which a photon enters a pixel of the wrong color, or electrical
means, in which a charge carrier generated within one pixel diffuses into a neighboring pixel.
Chief ray angle. Oblique rays that pass through the center of a lens system aperture stop. Color filter ar-
ray, metal, and micro lens shifts are determined by the chief ray angle of the optical system. In general,
optical systems with smaller CRA are desired to minimize color artifacts
Digital number. The number of bits (8, 12, 14, … ) should also be specified.
Differential nonlinearity (for ADCs)
Dark signal nonuniformity. This parameter characterizes the degree of nonuniformity in dark leakage cur-
rents, which can be a major source of fixed pattern noise.
A parameter that characterizes the optically active percentage of a pixel. In theory, it is the ratio of the
actual QE of a pixel divided by the QE of a photodiode of equal area. In practice, it is never measured.
An instrument that produces a monochromatic beam of light. It typically consists of a broadband light
source such as a tungsten lamp and a diffraction grating for selecting a particular wavelength.
Integral nonlinearity (for ADCs)
Light flux per unit area in photometric units (lux)
Infrared. IR light has wavelengths in the approximate range 750 nm to 1 mm.
Light flux per unit area in radiometric units (W/m 2 )
The persistence of signal after pixel reset when the irradiance changes from high to low values. In a video
stream, lag appears as ‘ghost’ images that persist for one or more frames.
Photometric unit of luminance (at 550 nm, 1 lux = 1 lumen/m 2 = 1/683 W/m 2 )
Near Infrared. NIR is part of the infrared portion of the spectrum and has wavelengths in the approximate
range 750 nm to 1400 nm.
Variation of pixel signals within a region of interest (ROI). The ROI typically is a rectangular portion of the
pixel array and may be limited to a single color plane.
Units for light measurement that take into account human physiology.
Measurement in which a bare imager (no external lens) is irradiated with uniform light from dark to satura-
tion levels. Typically the source is collimated, monochromatic 550 nm light. Chapter 2 of J. Janesick’s
book, Scientific Charge Coupled Devices, describes the technique in detail.
Parasitic light sensitivity. Parasitic discharge of sampled information in pixels that have storage nodes.
Photo-response nonuniformity. This parameter characterizes the spread in response of pixels, which is a
source of FPN under illumination.
Quantum efficiency. This parameter characterizes the effectiveness of a pixel in capturing photons and
converting them into electrons. It is photon wavelength and pixel color dependent.
Units for light measurement based on physics.
Noise associated with all circuitry that measures and converts the voltage on a sense node or photodiode
into an output signal.
The process by which a pixel photodiode or sense node is cleared of electrons. Soft reset occurs when the
reset transistor is operated below the threshold. Hard reset occurs when the reset transistor is operated
above threshold.
