1. An imaging control circuit for collecting object image data for an object presented on a portion of a surface of a display panel, the imaging control circuit comprising:
a first circuit, adapted to receive touch sensing signals from a set of touch sensors located in the display panel;
a second circuit, adapted to receive object image sensing signals from a set of imaging sensors, wherein the object image sensing signals are associated with the object detected on the surface of the display panel; and
a third circuit, adapted:
to determine a location of the object from the touch sensing signals; and
to generate a variable sized object imaging zone based on a location and a size of an object image, wherein the variable sized object imaging zone comprises a variable subset of the imaging sensors, wherein the third circuit is adapted to perform a remapping operation when object spans adjacent logical image sensing channels.
