The standard measure of photodiode performance (regardless of whether it is in an imager or not). Units
A measure of pixel performance that characterizes the rise of the photodiode or sense node signal in Volts
The photon wavelength dependence of sensitivity or responsivity.
Noise due to variation in the reset level of a pixel. In 3T pixel designs, this noise has a component (in units
of volts) proportionality constant depending on how the pixel is reset (such as hard and soft). In 4T pixel
designs, reset noise can be removed with CDS.
are typically A/W and are dependent on the incident light wavelength. Note that responsivity and sensitivity
are used interchangeably in image sensor characterization literature so it is best to check the units.
Phenomenon in which the signal level decreases with increasing light intensity. It typically occurs at irradi-
ance levels much higher than saturation, such as an image taken of the sun.
Region of interest. The area within a pixel array chosen to characterize noise, signal, crosstalk, and so on.
The ROI can be the entire array or a small subsection; it can be confined to a single color plane.
Variation of row mean signal strengths. The human eye is sensitive to line patterns, so this noise is ana-
lyzed separately.
In 4T pixel designs, a capacitor used to convert charge into voltage. In 3T pixel designs it is the photodi-
ode itself.
upon illumination with light. Units are typically V/(W/m
wavelength. Sensitivity measurements are often taken with 550 nm incident light. At this wavelength, 1
683 lux = 1 W/m
used interchangeably in image sensor characterization literature so it is best to check the units.
Noise that arises from measurements of discretised quanta (electrons or photons). It follows a Poisson
distribution with the strength of the noise increasing as the square root of the signal.
Signal-to-noise ratio. This number characterizes the ratio of the fundamental signal to the noise spectrum
up to half the Nyquist frequency.
Noise that varies from frame to frame. In a video stream, temporal noise is visible as twinkling pixels.
Integration time.
