H04N 25/571

Definition

(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)

Definition

• Controlling the sensor dynamic range using image sensors with pixel circuits having a non-linear response;
• Driving and control thereof.

The non-linear response can be achieved in different ways, for example, by using a specific photodetector, by controlling the reset or the transfer gate driving signals, by controlling the gain, or by using non-linear amplifiers.

Beziehungen zu anderen Klassifikationsstellen

Details of control of the charge storable in the pixel are classified in group H04N 25/59.

While group H04N 25/58 covers extending the dynamic range by using multiple exposures, group H04N 25/571 covers defining the response characteristic (or the Opto Electronic Conversion Function) of the sensor during a single exposure.
