Patent ID: 7471327

Claim:
A method of operating an imaging apparatus, the apparatus including a plurality of groups of photosensors, wherein a first subset of groups of photosensors is substantially evenly distributed along a linear array and is substantially interleaved with the second subset of groups of photosensors along the linear array, a first output line, and a second output line, comprising: in a first mode, transferring signals from a first subset of groups of photosensors to the first output line, and transferring signals from a second subset of groups of photosensors to the second output line; and in a second mode, for each of a plurality of groups of photosensors, transferring signals from a first photosensor in the group to the first output line, and transferring signals from a second photosensor in the group to the second output line; wherein, in the first mode or the second mode, signals from adjacent photosensors or groups of photosensors on the first and second output lines overlap over time.
