Sensor Cleaning

Removing dust from the sensor's cover glass, either by the camera's own vibrating filter or manually with a blower or swab.

Sensors & Digital Capture

Sensor Cover Glass

The protective glass stack in front of the sensor, incorporating the infrared cut and any low-pass filtering.

Sensors & Digital Capture

Sensor Dust

Particles settling on the sensor's cover glass, which appear as dark spots in the image at small apertures.

Sensors & Digital Capture

Sensor Saturation

The condition in which a photosite has reached its full-well capacity and can record no additional light.

Sensors & Digital Capture

Shot Noise

The unavoidable randomness in the arrival of photons, which produces grain even from a perfect sensor.

SNR = √N e⁻ (electrons)
Sensors & Digital Capture

Signal-to-noise Ratio

The ratio between the useful signal recorded and the noise accompanying it, which determines apparent image cleanliness.

SNR = signal / noise dB or ratio
Sensors & Digital Capture

Stacked Sensor

A design in which the sensor is bonded directly to a separate processing and memory layer beneath it.

Sensors & Digital Capture

Stuck Pixel

A photosite permanently reporting its maximum value, appearing as a fixed bright dot regardless of exposure.
