Image sensors having pixel-binning with configurable shared floating diffusion

A method comprising:

• enabling a pixel binning configuration in an image sensor;
• measuring a sampled indication of charge at one or more enabled floating diffusion regions;
• comparing the sampled indication of charge to a threshold;
• and
• responsive to determining the sampled charge exceeds the threshold, enabling one or more bridges associated with one or more of the enabled floating diffusion regions.

A non-transitory computer-readable medium comprising processor-executable instructions configured to cause a processor to:

• enabling a pixel binning configuration in an image sensor;
• measuring a sampled indication of charge at one or more enabled floating diffusion regions;
• comparing the sampled indication of charge to a threshold;
• and
• responsive to determining the sampled indication of charge exceeds the threshold, enabling one or more bridges associated with one or more of the enabled floating diffusion regions.

An image sensor system comprising:

• a plurality of means for receiving light;
• means for releasing electrons in response to receiving photons coupled to the means for receiving light;
• a plurality of means for accumulating electric charge coupled to the means for releasing electrons;
• and
• means for selectively electrically coupling two means for accumulating electric charge to allow a transfer of charge between the two means for accumulating electric charge.
