H04N 25/583

Definition

Diese Klassifikationsstelle umfasst:

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

Controlling sensor dynamic range using two or more simultaneously acquired exposures with different integration times, including

• providing pixels for multiple exposures, such as long and short exposure time pixels;

• providing pixels that are read out several times non-destructively during a single exposure period, wherein the readout signals are combined to generate a high dynamic range signal;
• providing pixels that have charge partially transferred to a storage node (charge skimming) during the exposure period, wherein the signals from the partial readout and from the end of exposure are combined to generate a high dynamic range signal.

Beziehungen zu anderen Klassifikationsstellen

While group H04N 25/533 covers control of exposure time in different regions of the image sensor, group H04N 25/583 provides for the simultaneous acquisition of two or more exposures using different integration times which are combined in such a way that a new high dynamic range image signal is generated. If a partial or non-destructive readout is used only for setting the exposure period of the pixel, classification should be made in H04N 25/533.
