Sensors & Digital Capture

Phase-detect Pixel

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.

Sensors & Digital Capture

Photodiode

The semiconductor junction within a photosite that converts arriving photons into electrical charge.

e⁻ (electrons)
Sensors & Digital Capture

Photosite

A single light-collecting element on a sensor, corresponding to one pixel in the final image.

µm
Sensors & Digital Capture

Pixel Binning

Combining the signal from several adjacent photosites into one output pixel to improve signal-to-noise ratio.

SNR gain ≈ √n × (2×2, 4×4)
Sensors & Digital Capture

Pixel Pitch

The centre-to-centre distance between adjacent photosites on a sensor.

Pitch = sensor width / horizontal pixels µm
Sensors & Digital Capture

Pixel Shift Multi-shot

A mode that moves the sensor by precise sub-pixel amounts between exposures and combines the frames into one higher-quality image.
