Sensors and camera systems
Tutorials on the sensor object (photodetector array, color filter array, pixel electronics, and noise) and on camera-level effects that depend on the sensor. See Sensor for the conceptual page and Tutorials for the full topic index.
Sensor basics
-
t_sensorColorFilters (source) Create, save, load, and attach a set of color filters to a sensor.
-
t_sensorSpatialResolution (source) Illustrates how pixel size (sensor spatial resolution) relates to aliasing.
-
t_sensorReadRaw (source) Reads a camera raw (DNG) file and places the data into a sensor structure.
Exposure, noise, and color
-
t_sensorExposureColor (source) Shows how over-exposure introduces color errors in the rendered image.
-
t_sensorFPN (source) Illustrates control of fixed-pattern noise (DSNU/PRNU) in the sensor computation.
-
t_sensorInputRefer (source) Calculates the mean photon absorption rate at a detector.
-
t_sensorEstimation (source) Reviews sensor spectral quantum-efficiency estimation (Psych 221).
Camera-level effects
-
t_cameraNoise (source) Uses the camera object to compare images rendered with different sensor noise and light levels.
-
t_cameraAntiAliasing (source) Illustrates the effect of the sensor's anti-aliasing filter on a high-frequency scene.
-
t_cameraCompute (source) Illustrates camera-object creation and computation as a compact alternative to separate oi/sensor/ip calls.
