Abstract:
1. An image sensor array comprising: a first CCD image sensor configured to output a plurality of first signal voltages from a first output terminal; a second CCD image sensor configured to output a plurality of second signal voltages from a second output terminal; a switch circuit selectively connecting one of said first and second output terminals to a signal voltage output terminal; and a timing generator circuit responsive to a basic clock for generating first and second control signals and switch control signals, said first and second control signals being used for controlling generation of said plurality of first and second signal voltages, respectively, and said switch control signals being used for controlling said switch circuit, wherein said timing generator circuit controls said first and second CCD image sensors so that said first and second CCD image sensors output said plurality of first signal voltages and said plurality of second signal voltages, alternately, wherein said timing generator circuit controls said switch circuit so that said switch circuit outputs from said signal voltage output terminal one of said plurality of first signal voltages and one of said plurality of second signal voltages, alternately, wherein said timing generator circuit further controls said first and second CCD image sensors and said switch circuit, so that said plurality of first signal voltages are successively outputted from said signal voltage output terminal and then said plurality of second signal voltages are successively outputted from said signal voltage output terminal, and wherein said image sensor array is adapted to selectively output signal voltages for an original resolution of said image sensor array and signal voltages for a resolution of one half of said original resolution.
