Patent ID: 7741589

Claim:
An imager comprising: a pixel array comprising: a plurality of pixels arranged in rows and columns, each of said pixels comprising a photosensor for generating charge in response to light and a transfer transistor for transferring said charge from said photosensor to an associated floating diffusing region; and first and second transfer transistor control lines associated with at least one row of pixels, at least one pixel in said at least one row having a transfer transistor gate connected to the first transfer transistor control line and a plurality of other pixels in said at least one row having respective transfer transistor gates connected to the second transfer transistor control line, a control circuit coupled to said first and second transfer transistor control lines for providing at least one first transfer control signal to said first transfer transistor control line during an integration period of said plurality of other pixels to transfer charges generated by said at least one pixel to an output circuit; and a light control circuit responsive to charges transferred to said output circuit for controlling a duration of said integration period of said plurality of other pixels, wherein said control circuit is configured to provide at least one second transfer control signal to the second transfer transistor control line at an end of said first integration period to transfer charges generated by the photosensors of said plurality of other pixels during said first integration period.
