Abstract:
Signals representative of total photocharge integrated within respective image-sensor pixels are read out of the pixels after a first exposure interval that constitutes a first fraction of a frame interval. Signals in excess of a threshold level are read out of the pixels after an ensuing second exposure interval that constitutes a second fraction of the frame interval, leaving residual photocharge within the pixels. After a third exposure interval that constitutes a third fraction of the frame interval, signals representative of a combination of at least the residual photocharge and photocharge integrated within the pixels during the third exposure interval are read out of the pixels.

Claim (Index 13):
An integrated-circuit image sensor comprising:\n a pixel array; a transfer-gate signal line coupled to transfer gates of respective pixels within the pixel array and constituting the sole signal line that controls charge transfer between respective photodiodes of the pixels and respective floating diffusion nodes; and control circuitry to assert on the transfer-gate signal line during an image frame interval:\n a first control signal pulse having a first magnitude to enable photocharge integrated within respective photodiodes of the pixels since the start of the image frame interval to be transferred in its entirety to the respective floating diffusion nodes; \n a second control signal pulse having a magnitude less than the first magnitude to enable transfer, from the photodiodes of the pixels to the respective floating diffusion nodes, of photocharge integrated within the photodiodes in excess of a threshold photocharge level after assertion of the first control pulse; and \n a third control signal pulse having the first magnitude to enable further photocharge to be transferred from the photodiodes to the respective floating diffusion nodes.
