Sensors & Digital Capture
60 terms · page 3 of 3
Rolling Shutter Artefact
Distortion caused by a sensor being read out progressively, so different parts of the frame record at slightly different times.
Sensors & Digital CaptureSensor 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 CaptureSensor Cover Glass
The protective glass stack in front of the sensor, incorporating the infrared cut and any low-pass filtering.
Sensors & Digital CaptureSensor Crop Mode
A setting that records only part of the sensor's area, producing a smaller file with a narrower angle of view.
Sensors & Digital CaptureSensor Dust
Particles settling on the sensor's cover glass, which appear as dark spots in the image at small apertures.
Sensors & Digital CaptureSensor Saturation
The condition in which a photosite has reached its full-well capacity and can record no additional light.
Sensors & Digital CaptureShot Noise
The unavoidable randomness in the arrival of photons, which produces grain even from a perfect sensor.
Sensors & Digital CaptureSignal-to-noise Ratio
The ratio between the useful signal recorded and the noise accompanying it, which determines apparent image cleanliness.
Sensors & Digital CaptureStacked Sensor
A design in which the sensor is bonded directly to a separate processing and memory layer beneath it.
Sensors & Digital CaptureStuck Pixel
A photosite permanently reporting its maximum value, appearing as a fixed bright dot regardless of exposure.
Sensors & Digital CaptureWhite Level
The numerical value at which a sensor's photosites are considered saturated, defining the clipping point of a raw file.
Sensors & Digital CaptureX-Trans Filter
An alternative colour filter array using a six-by-six pattern with green in every row and column.
