Phase-detect Pixel
Sensors & Digital Capture
count
A photosite masked on one side, or split in two, so it sees the scene through only part of the lens and can contribute to focus measurement.
Photodiode
Sensors & Digital Capture
e⁻ (electrons)
The semiconductor junction within a photosite that converts arriving photons into electrical charge.
Photosite
Sensors & Digital Capture
µm
A single light-collecting element on a sensor, corresponding to one pixel in the final image.
Pixel Binning
Sensors & Digital Capture
× (2×2, 4×4)
Combining the signal from several adjacent photosites into one output pixel to improve signal-to-noise ratio.
SNR gain ≈ √n
Pixel Pitch
Sensors & Digital Capture
µm
The centre-to-centre distance between adjacent photosites on a sensor.
Pitch = sensor width / horizontal pixels
Pixel Shift Multi-shot
Sensors & Digital Capture
count (4, 8, 16 frames)
A mode that moves the sensor by precise sub-pixel amounts between exposures and combines the frames into one higher-quality image.
