Abstract
The present invention provides a pixel circuit comprising a pinned photodiode, at least one first transfer gate for electrically connecting the pinned photodiode to at least one storage node and at least one further transfer gate. The at least one further gate can connect the at least one storage node with at least one floating diffusion node. At least one merging switch is included for allowing connection between the at least one floating diffusion node with one or more capacitor nodes, which can accept charge that exceeds the maximum storage capacity of the storage node.
