Spezielle Klassifizierungsregeln

Where the solid state image sensor function is classified in groups H04N 25/00-H04N 25/683, classification should also be made in the group corresponding to the sensor technology, i.e. H04N 25/71, H04N 25/76 or H04N 25/79. For example, dark current correction for CCDs should be classified in both H04N 25/63 and H04N 25/71.

Glossar

Image sensor

Sensor that detects and conveys the information that constitutes an image. An image sensor may do so by producing a signal that represents location-dependent attenuation of light (as the light passes through or reflects off a medium). The signal is an electric signal such as an electric voltage or current. The light an image sensor may detect is not limited to visible light but can be electromagnetic radiation in other wavelengths (e.g. infrared, ultraviolet, X-rays, gamma rays).
