1. An imaging device, comprising:
- an array of pixels arranged in columns comprising signal means which serve to enable any given pixel within any given column; and
an integration period selection circuit associated with each column, wherein said integration period selection circuit is configured to receive a first signal from a first transistor within an enabled pixel indicating when said enabled pixel within said column is currently selected and output a signal with at least in part initiates a selected integration period for said enabled pixel, wherein an integration period for each pixel within said array of pixels is dynamically determined within a corresponding image acquisition sequence, and said image acquisition sequence being a period for acquiring a single frame.
