Abstract:
1. A semiconductor imaging device, comprising: a sensing array having a plurality of sensing pixels; at least one analog-to-digital converter coupled to said sensing array and configured to convert said analog pixel signals received from said sensing array into respective digital pixel signals, each of said digital pixel signals having a plurality of bits; and a first storage location and a second storage location, each location coupled alternatively to said analog-to-digital converter and operable to store digital pixel signals from said analog-to-digital converter, said first and second storage locations being coupled to read a first digital pixel signal generated from a first sensing pixel into one of said first and second storage locations while the other of said first and second storage locations outputs a second digital pixel signal that is generated from a second different sensing pixel which was converted by said analog-to-digital converter before conversion of said first digital pixel signal.
