TermDescription
Analog-to-Digital Converter (ADC) The circuit that converts analog sensor voltage to a digital number
Auto White Balance A camera mode that re-balances every frame on the assumption that the scene averages to gray; wrong for stained tissue.
Binning Combining adjacent pixels to increase sensitivity at the cost of spatial resolution
Bit Depth The number of bits used to represent each pixel intensity value
Clipping A pixel or channel at the camera's maximum value; anything brighter is recorded as the same number, so the information i...
Dark Frame An image taken with no light reaching the camera, at the same exposure; it records the camera's offset so it can be subt...
Dynamic Range The span from dimmest to brightest
Frame Rate Images per second
Full Well Capacity Maximum electrons per pixel
Pixel Size The physical dimension of each sensor element
Quantization The process of mapping continuous intensity values to discrete digital levels
Quantum Efficiency Photon to electron conversion
Read Noise The electronic noise floor
sCMOS Camera The modern standard for fluorescence imaging
Sensor Area How big is the 'film'
White Balance Scaling a color camera's red, green and blue gains so that blank glass records as neutral gray under your lamp.
